The Efficacy of Acupuncture in Post-Operative Pain Management: A Systematic Review and Meta-Analysis. PLoS One. 2016;11:e0150367. [PMID: 26959661 PMCID: PMC4784927 DOI: 10.1371/journal.pone.0150367]

A randomized controlled study on acupuncture for peri-operative pain after open radical prostatectomy

OBJECTIVES

To evaluate the advantages of adding acupuncture to standard postoperative pain management for open radical prostatectomy (RP).

MATERIALS AND METHODS

A randomized controlled trial (1:1:1) comparing routine postoperative analgesic care (control [CON]) vs the addition of press tack needle acupuncture (ACU) or press tack placebo acupressure (SHAM) for pain management after open RP was performed. A total of 126 patients were enrolled between February 2020 and April 2021. After open RP, the CON group received standard postoperative analgesia, the ACU group received long-term acupuncture with press tacks at specific points (P-6, Shenmen and SP-6) along with standard analgesia, and the SHAM group received placebo press tacks at the same acupuncture points alongside standard analgesia. The primary endpoint was postoperative pain measured on a numeric rating scale, the NRS-11, calculated as the area under the curve. The cumulative use of routine postoperative analgesics, time to first defaecation, and quality of life were analysed using the Kruskal-Wallis rank sum test, Fisher's exact test, and Pearson's chi-squared test.

RESULTS

The ACU group reported significantly less postoperative pain compared to the SHAM (P = 0.007) and CON groups (P = 0.02). There were no significant difference in median (interquartile range) cumulative pain medication usage, time to first defaecation (CON: 37 [33, 44] h; SHAM: 37 [33, 42] h; ACU: 37 [33, 41] h; P > 0.9), or health status at discharge (EuroQol five-dimension, five-level general health assessment questionnaire: CON: 70 [65-83]; SHAM: 70 [60-80]; ACU: 70 [50-80]).

CONCLUSION

Incorporating acupuncture into postoperative pain management can improve patient postoperative outcomes.

Efficacy of different strategies for reducing labor pain: A Bayesian analysis

BACKGROUND

The effectiveness of different medical interventions in managing labor pain has yielded mixed results. Therefore, this systematic review and network meta-analysis aimed to provide a comprehensive summary of the available evidence on the impact of different strategies for reducing labor pain.

METHODS

We systematically searched 3 English databases (Pubmed, Embase and the Cochrane Library) from inception to January 2023. Randomized controlled trials (RCTs) or controlled clinical trials that investigating the effects of different strategies for reducing labor pain were included in this network meta-analysis. Risk of bias (ROB) was assessed using the Cochrane ROB tools. Network meta-analysis was performed using the R software (version 4.2.1) with gemtc package.

RESULTS

A total of 9 studies involving 823 patients, including 9 treatments (acupressure, birth ball exercise, Bonapace method, distraction techniques, ice pressure, LI4 acupressure, lidocaine spray, smartphone-based music intervention and placebo). The surface under the cumulative ranking (SUCRA) shows that Bonapace method ranked first (SUCRA, 79.5%), LI4 acupressure ranked second (SUCRA, 65.6%), distraction technique ranked third (SUCRA, 57.6%), birth ball exercise ranked fourth (SUCRA, 51.8%).

CONCLUSIONS

According to the results of the network meta-analysis, among the different strategies examined, the Bonapace Method stands out as the most effective nonpharmacological intervention for reducing labor pain. The results of this meta-analysis can aid both patients and healthcare professionals in choosing the most effective techniques to reduce labor pain.

Efficacy of acupuncture on cancer pain: A systematic review and meta-analysis

BACKGROUND

Pain associated with cancer is one of the greatest causes of reduced quality of life in patients. Acupuncture is one of the treatments used to address this issue, with the great advantage of having little or no side effects, especially when compared with pharmacological pain-killers.

OBJECTIVE

The aim of this systematic review and meta-analysis was to evaluate the current evidence regarding the efficacy of acupuncture for cancer pain.

SEARCH STRATEGY

Six electronic databases (PubMed, EBSCO, Cochrane Library, Scielo, b-On and Scopus) were searched for relevant articles about pain relief in cancer patients from their beginning until 2022 using MeSH terms such as "acupuncture," "electroacupuncture," "ear acupuncture," "acupuncture analgesia," ''oncological pain," and "cancer pain."

INCLUSION CRITERIA

Studies included were randomized controlled trials (RCTs) where acupuncture was compared with no treatment, placebo acupuncture or usual care.

DATA EXTRACTION AND ANALYSIS

Three independent reviewers participated in data extraction and evaluation of risk of bias, and a meta-analysis was conducted. The primary outcome was pain intensity, measured with the visual analog scale, numeric rating scale, or brief pain inventory. Secondary outcomes also assessed were quality of life, functionality, xerostomia, pain interference, and analgesic consumption. Results were expressed as standardized mean difference (SMD) with 95% confidence interval (CI).

RESULTS

Sixteen RCTs with a total of 1124 participants were included in the meta-analysis, with the majority of the studies presenting a low or unclear risk of bias. Acupuncture was more effective in reducing pain than no treatment (SMD = -0.90, 95 % CI [-1.68, -0.12]), sham acupuncture (SMD = -1.10, 95 % CI [-1.59, -0.61]) or usual care (SMD = -1.16, 95 % CI [-1.38, -0.93]).

CONCLUSION

The results of this study suggest that acupuncture may be an effective intervention to reduce pain associated with cancer. Despite some limitations due to the low quality and small sample size of some included studies, as well as the different types and stages of cancer, acupuncture might provide an effective and safe treatment to reduce cancer pain.

Effects of transcutaneous electrical acupoint stimulation on early postoperative pain and recovery: a comprehensive systematic review and meta-analysis of randomized controlled trials

Background

Previous studies have indicated beneficial outcomes of transcutaneous electrical acupoint stimulation (TEAS), but high-quality and comprehensive meta-analyses are lacking. The aim was to quantitatively analyze the efficacy and safety of perioperative TEAS on postoperative pain and recovery.

Methods

PubMed, Web of Science, EMBASE, and the Cochrane Library were searched through July 2022. Randomized controlled trials (RCTs) that examined the perioperative application of TEAS in adults compared with sham-TEAS and/or non-TEAS were eligible. Cumulative analgesic consumption within 24 h and rest pain scores at 2, 6, 12, and 24 h postoperatively were the two co-primary outcomes.

Results

Seventy-six RCTs (n = 9,665 patients) were included. Patients treated with TEAS experienced a reduction in clinical importance in cumulative analgesic (morphine equivalent) consumption (WMD: -14.60 mg, 97.5% CI: -23.60 to -5.60; p < 0.001) and a reduction in statistical importance in rest pain scores at multiple time points within the first 24 postoperative hours. The secondary outcome analysis also identified clinically significant recovery benefits to TEAS during the first 24 h after surgery. Furthermore, TEAS could effectively reduce opioid-related side effects and did not increase serious side effects.

Conclusion

This article describes current evidence about TEAS intervention on early postoperative pain and recovery. The results support the effectiveness of TEAS, but more high-quality evidence of clinical applicability is also needed.

Combined rectus sheath block with transverse abdominis plane block by one puncture for analgesia after laparoscopic upper abdominal surgery: a randomized controlled prospective study

BACKGROUND

Rectus sheath block (RSB) and transversus abdominis plane block (TAPB) have been shown to reduce opioid consumption and decrease postoperative pain scores in abdominal surgeries. However, there are no reports about the one-puncture technique of RSB combined with TAPB for perioperative pain management during laparoscopic upper abdominal surgery.

METHODS

A total of 58 patients were randomly assigned to the control group (C), the TAP group (T), and the one-puncture technique of RSB combined with TAPB group (RT). The patients in group C did not receive any regional block. The patients in group T received ultrasound-guided subcostal TAPB with 30 mL of 0.33% ropivacaine on each side. The patients in the RT group received a combination of RSB and TAPB with 15 mL of 0.33% ropivacaine in each plane by one puncture technique. All patients received postoperative patient-controlled intravenous analgesia (PCIA) after surgeries. The range of blocks was recorded 20 min after the completion of the regional block. The postoperative opioid consumption, pain scores, and recovery data were recorded, including the incidence of emergence agitation (EA), the times of first exhaust and off-bed activity, the incidence of postoperative nausea and vomiting, dizziness.

RESULTS

The range of the one-puncture technique in group RT covered all areas of surgical incisions. The visual analogue scale (VAS) score of the RT group is significantly lower at rest and during coughing compared to groups T and C at 4, 8, 12, and 24 h after surgery, respectively (P < 0.05). The consumption of sufentanil and the number of postoperative compressions of the analgesic pumps at 24 and 48 h in the RT group are significantly lower than those in groups T and C (P < 0.05). The incidence of EA in the RT group is significantly lower than that in groups T and C (P < 0.05).

CONCLUSION

The one-puncture technique of RSB combined with TAPB provides effective postoperative analgesia for laparoscopic upper abdominal surgery, reduces the incidence of EA during PACU, and promotes early recovery.

BACKGROUND

The objective of this study is to study the pain relief effects of angiopuncture therapy in patients with postoperative pain.

METHODS

Forty-one patients were randomly selected based on the inclusion and exclusion criteria. Doppler imaging was performed to locate the cutaneous perforator. Angiopuncture was performed on the first postoperative day. A Numerical Rating Scale was used to evaluate the degree of pain before and after angiopuncture. Utilizing the paired t test or Wilcoxon signed rank test, all pre- and post-data were examined, and further subgroup analysis based on time was performed.

RESULTS

Variance analysis revealed a significant difference before and after angiopuncture (P < .05). The results of the subgroup analysis showed the pain-relieving effect of angiopuncture for postoperative pain patients at the time points of 6 hours, 12 hours, 24 hours, 48 hours, and 72 hours was apparent (P < .05).

CONCLUSION

The angiopuncture therapy approach may assist in pain relief in patients with postoperative pain.

Acupuncture as a Complementary Treatment Modality in the Post-Anesthesia Care Setting: A Feasibility Study

Introduction: Postoperative pain management and postoperative nausea and vomiting are a persistent challenge for both health care providers and patients. Acupuncture is an effective and safe modality for the management of pain and nausea, and has the potential to play a key role in postoperative pain management. This study explores the utility and feasibility of acupuncture in the immediate postoperative setting. Methods: In a retrospective case-control study, 22 patients who underwent elective surgeries and received acupuncture in the post-anesthesia care unit (PACU) were compared with 88 case controls. Indications for acupuncture therapy included persistent pain, nausea, or anxiety. Patient satisfaction and symptom improvement after acupuncture were assessed. PACU nurses and patients were queried on their perspectives on using this therapy. Demographic data, perioperative opioid consumption, pain score in the PACU, incidence of postoperative nausea, PACU length of stay, and unintended hospital admission were assessed. The groups with/without acupuncture were compared using Wilcoxon rank sum test or Fisher's exact test as appropriate. Results: A total of 78.9% of patients receiving acupuncture felt improvement in their symptoms. 94.7% of recovery nurses who cared for patients who received acupuncture felt that it was helpful and 78.9% did not believe it was disruptive. Patients who opted for acupuncture had a statistically significant higher overall median (interquartile range) pain score in the PACU (7.0 [5.2, 9.5] vs. 5.0 [3.0, 7.0], p = 0.009) and higher postoperative opioid consumption (22.5 [9.8, 44.8] vs. 15.0 [0.0, 30.0], p = 0. 03). There was no difference between total perioperative opioid consumption between groups (p = 0.94). Conclusions: Most patients who received acupuncture therapy in the PACU were satisfied with their therapy and would recommend it to future patients undergoing surgery. Most recovery nurses felt it was helpful, was not disruptive, and would like to see it utilized in the PACU.

Risk Factors for Severe Pain and Impairment of Daily Life Activities after Cesarean Section-A Prospective Multi-Center Study of 11,932 Patients

Cesarean section (CS) is the most widely performed and one of the most painful surgeries. This study investigated postoperative pain after CS using patient-related outcomes (PROs) to identify risk factors for severe pain. The secondary outcome was to evaluate the influence of surgery indication (primary CS (PCS) vs. urgent CS (UCS)). This multi-center, prospective cohort study included data submitted to the pain registry "quality improvement in postoperative pain treatment" (QUIPS) between 2010 and 2020. In total, 11,932 patients were evaluated. Median of maximal pain was 7.0 (numeric rating scale (NRS) 0 to 10); 53.9% suffered from severe pain (NRS ≥ 7), this being related to impairment of mood, ambulation, deep breathing and sleep, as well as more vertigo, nausea and tiredness (p < 0.001). Distraction, relaxation, mobilization, having conversations, patient-controlled analgesia (PCA) and pain monitoring were shown to be protective for severe pain (p < 0.001). Maximal pain in PCS and UCS was similar, but UCS obtained more analgesics (p < 0.001), and experienced more impairment of ambulation (p < 0.001) and deep breathing (p < 0.05). Severe pain has a major effect on daily-life activities and recovery after CS, and depends on modifiable factors. More effort is needed to improve the quality of care after CS.

Hotspots and Trends in Research on Treating Pain with Electroacupuncture: A Bibliometric and Visualization Analysis from 1994 to 2022

Purpose

Electroacupuncture is widely used to pain management. A bibliometric analysis was conducted to identify the hotspots and trends in research on electroacupuncture for pain.

Methods

We retrieved studies published from 1994-2022 on the topic of pain relief by electroacupuncture from the Web of Science Core Collection database. We comprehensively analysed the data with VOSviewer, CiteSpace, and bibliometrix. Seven aspects of the data were analysed separately: annual publication outputs, countries, institutions, authors, journals, keywords and references.

Results

A total of 2030 papers were analysed, and the number of worldwide publications continuously increased over the period of interest. The most productive country and institution in this field were China and KyungHee University. Evidence-Based Complementary and Alternative Medicine was the most productive journal, and Pain was the most co-cited journal. Han Jisheng, Fang Jianqiao, and Lao Lixing were the most representative authors. Based on keywords and references, three active areas of research on EA for pain were mechanisms, randomized controlled trials, and perioperative applications. Three emerging trends were functional magnetic resonance imaging (fMRI), systematic reviews, and knee osteoarthritis.

Conclusion

This study comprehensively analysed the research published over the past 28 years on electroacupuncture for pain treatment, using bibliometrics and science mapping analysis. This work presents the current status and landscape of the field and may serve as a valuable resource for researchers. Chronic pain, fMRI-based mechanistic research, and the perioperative application of electroacupuncture are among the likely foci of future research in this area.

Electroacupuncture for Pain Relief After Endoscopic Sinus Surgery: A Randomized Controlled Trial

Postoperative pain is a common problem after endoscopic sinus surgery (ESS). Electroacupuncture (EA) is proven to be effective in relieving postoperative pain. However, EA has not been studied in patients undergoing ESS. This study was designed to evaluate the efficacy and safety of EA compared to a sham control in relieving pain after ESS. A total of 62 patients were randomly allocated to receive either EA (n = 31) or sham EA (n = 31) for 5 sessions, 30 minutes per session for 4 days (2 hours before and 2 hours after surgery, and 3 sessions daily for the following 3 days). There were no significant differences between the 2 groups with regard to demographic characteristics. Compared to the sham EA group, the EA group showed a significantly greater reduction in the pain intensity of single daily scoring with a numerical rating scale at the day following surgery (postoperative day 1, POD1) (-1.35; 95% confidence interval [CI], -1.74 to -0.97; P < .001) and POD2 (-1.16; 95% CI, -1.55 to -0.77; P < .001), whereas no significant between-group difference was detected at the day of surgery (POD0), POD3 or POD6. Intraoperative heart rate and mean blood pressure in the EA group showed a more stable trend. A significant improvement was found for an actigraphy-measured average time of night wakings, recovery time from anesthesia, and quality of recovery-15 in the EA group. No severe adverse events occurred during the trial. Our results demonstrate that EA can serve as an effective adjuvant therapeutic tool for pain relief after ESS. PERSPECTIVE: This randomized sham-controlled, patient-and-assessor blinded trial provided evidence for the first time that EA can relieve postoperative pain and other symptom management in patients after ESS.

Research trends of acupuncture therapy on postoperative nausea and vomiting from 2011 to 2023: A bibliometric analysis

BACKGROUND

The utilization of acupuncture as a therapeutic intervention for the management of postoperative nausea and vomiting has experienced a notable increase in its popularity, and the purpose of this analysis is to provide a comprehensive understanding of the level of concern within the academic discipline and the main contributors and their partnership, as well as to identify research focal points and trends.

METHODS

A comprehensive search was carried out to identify relevant articles on the topic of acupuncture therapy for PONV in the Web of Science and China National Knowledge Internet. The search spanned from January 1, 2011, to June 6, 2023. The annual publications were count to see the degree of scholarly attention devoted to the discipline and how it has changed over time. A statistical analysis of article distribution across various journals was conducted to serve a rough indicator for assessing the quality of articles. And a bibliometric analysis was conducted using the software CiteSpace to visually analyze various aspects of the literature. Analyze authors, institutions and countries to identify the main contributors and their collaborative relationship; and analyze keywords and references to explore research hotspots and trends.

RESULTS

This study examined a comprehensive collection of 819 articles focused on acupuncture therapy for PONV, demonstrating a varying upward trend in the quantity of publications. Notably, the most productive author and institution were identified as Zheng Man and Guangzhou University of Traditional Chinese Medicine, respectively. While China had the highest number of publications, the United States held a greater prominence in this specific field. Collaboration among contributors was found to be weak. High-frequency keywords in the publications included "transcutaneous electrical acupoint stimulation," "electroacupuncture," "pain," and so forth. The literature with the highest citation count pertained to "Stimulation of the wrist acupuncture point PC6 for preventing postoperative nausea and vomiting," while the article with the highest centrality was "Consensus Guidelines for the Management of Postoperative Nausea and Vomiting." Several large clusters obtained from the references are also included "postoperative pain," "transcutaneous electrical acupoint stimulation". Nothing pertaining to mechanism study was found in the analysis results.

CONCLUSION

The utilization of acupuncture for the treatment of postoperative nausea and vomiting has been gaining increasing recognition, although there remains room for improvement in the quality of research conducted in this area. Chinese authors and institutions have emerged as significant contributors to this field, while the United States has demonstrated greater proficiency in fostering collaborative efforts. It is imperative to enhance collaboration among these contributors. The current focal points of acupuncture for PONV encompass pain management, electroacupuncture, auricular acupuncture, and transcutaneous electrical acupoint stimulation. Additionally, TEA and enhanced recovery after surgery have been identified as the forefronts of research in this particular domain. In addition, there is still much room for research in the aspect of mechanism and insurance coverage. This study provides an in-depth perspective on acupuncture for PONV, which offers reference material for clinicians with rational choice of therapeutic scheme, educators with hot topics, and researchers with valuable research directions.

Meta-analysis of the traditional Chinese medicine care model in relieving postoperative pain in patients with anorectal diseases

Objective

To explore the effect of traditional Chinese medicine (TCM) nursing on relieving postoperative pain in patients with anorectal diseases.

Method

Three English and three Chinese databases (PubMed, Embase, the Cochrane Library, the China National Knowledge Internet, Wanfang Data and the China Science and Technology Journal Database) were systematically searched for case-controlled or prospective studies evaluating the impact of TCM nursing on postoperative pain in patients with anorectal diseases from the date of library construction until June 20, 2022. The Newcastle-Ottawa Scale was adopted to evaluate the quality of the observational studies. The effect of TCM care on pain based on the Visual Analogue Scale (VAS), the effective pain relief rate, the wound healing time and the length of hospital stay were systematically analysed.

Result

After a systematic search and screening, a total of 15 documents were included in this study. The systematic evaluation showed that TCM care reduced the VAS score (mean difference (MD): 1.15（95 % Confidence Interval (CI): 1.96, -1.06; P < 0.00001) compared with conventional postoperative care methods. As TCM nursing time increased, there was a trend towards decreased VAS scores. Furthermore, TCM care was effective in providing pain relief (OR: 4.78; 95 % CI: 2.93,7.79; P < 0.00001) and reducing wound healing time (MD: 4.44; 95 % CI: 5.60, -3.27; P < 0.00001) and length of hospital stay (MD: 4.87; 95 % CI: 5.93, -3.82; P < 0.00001).

Conclusion

Traditional Chinese medicine nursing has a positive effect on the postoperative clinical results of patients with anorectal diseases, especially in relieving postoperative pain. The effect of traditional Chinese medicine nursing in relieving short-term postoperative pain in patients with anorectal diseases is obvious. However, there is no uniform standard for TCM nursing projects, which may lead to heterogeneity.

Analgesic effects of perioperative acupuncture methods: A narrative review

Postoperative pain occurs immediately after surgery. The most common perioperative analgesic methods are nerve block, patient-controlled intravenous analgesia, and patient-controlled epidural analgesia. However, overuse of opioid analgesics can cause many adverse reactions including excessive sedation, respiratory inhibition, postoperative nausea, and vomiting. In recent years, many clinical trials have shown that perioperative acupuncture has unique advantages in patients. Perioperative acupuncture can relieve intraoperative pain, improve postoperative pain management, reduce postoperative nausea and vomiting, and shorten the length of hospital stay. This study aimed to confirm the analgesic effect of perioperative acupuncture by reviewing studies on the different methods of perioperative acupuncture and their analgesic effects. The cited literature was searched in English and Chinese from PubMed, China National Knowledge Infrastructure, and Wanfang data, using the following keywords: "perioperative pain," "acupuncture," "electroacupuncture," and "perioperative analgesia." Studies published from 2005 to 2023 were included. All retrieved papers were read in detail. Perioperative acupuncture has benefits in reducing postoperative pain and opioid need. Although analgesic drugs are still the primary means of postoperative pain control, acupuncture provides a safe analgesic supplement or alternative. This review aimed to assist practitioners in choosing appropriate perioperative acupuncture methods by summarizing the recent literature on the role of different acupuncture approaches for perioperative pain management.

Analgesic effects of LI4 acupuncture during intrauterine device insertion: a randomized controlled clinical trial

PURPOSE

Intrauterine device (IUD) is one the most effective contraceptive methods with reversible long-term effects. However, the major drawback of IUD use is pain perception during the insertion of the device. The aim of this study is to investigate the effects of bilateral LI4 acupuncture, administered before IUD insertion, on pain perception.

METHODS

This is a prospective randomized controlled study. It was held in Community Health Center in Niğde, Turkiye. Individuals enrolled in the study were randomized into the acupuncture group and non-intervention group. Acupuncture group received bilateral LI4 acupuncture prior to IUD insertion while others received no interventions. After IUD insertion, 10 cm visual analog scale (VAS) score was evaluated at 3rd minute and at 10th minute. Health care provider performing the IUD insertion and VAS evaluation was blind to randomization.

RESULTS

In total 72 participants were included in the study. The VAS scores were significantly lower in the acupuncture group both at 3rd minute and at 10th minute (1.93 ± 1.68; 3.81 ± 1.95; p < 0.001 and 0.53 ± 0.84; 1.64 ± 1.10; p < 0.001 respectively). Linear regression analysis showed that acupuncture was a significant predictor for lowering VAS both at 3rd minutes and 10th minutes following IUD insertion (p < 0.001).

CONCLUSION

This is the first randomized controlled clinical study investigating the effects of acupuncture on pain control during IUD insertion. The results demonstrated that bilateral LI4 acupuncture provides significant pain relief at both cervical and fundal components. Acupuncture prior to IUD insertion is a significant predictor of lowering overall VAS scores of individuals.

Transcutaneous electrical acupoint stimulation in adult patients receiving gastrectomy/colorectal resection: A randomized controlled trial

BACKGROUND

Acupuncture promotes the recovery of gastrointestinal function and provides analgesia after major abdominal surgery. The effects of transcutaneous electrical acupoint stimulation (TEAS) remain unclear.

AIM

To explore the potential effects of TEAS on the recovery of gastrointestinal function after gastrectomy and colorectal resection.

METHODS

Patients scheduled for gastrectomy or colorectal resection were randomized at a 2:3:3:2 ratio to receive: (1) TEAS at maximum tolerable current for 30 min immediately prior to anesthesia induction and for the entire duration of surgery, plus two 30-min daily sessions for 3 consecutive days after surgery (perioperative TEAS group); (2) Preoperative and intraoperative TEAS only; (3) Preoperative and postoperative TEAS only; or (4) Sham stimulation. The primary outcome was the time from the end of surgery to the first bowel sound.

RESULTS

In total, 441 patients were randomized; 405 patients (58.4 ± 10.2 years of age; 247 males) received the planned surgery. The time to the first bowel sounds did not differ among the four groups (P = 0.90; log-rank test). On postoperative day 1, the rest pain scores differed significantly among the four groups (P = 0.04; Kruskal-Wallis test). Post hoc comparison using the Bonferroni test showed lower pain scores in the perioperative TEAS group (1.4 ± 1.2) than in the sham stimulation group (1.7 ± 1.1; P = 0.04). Surgical complications did not differ among the four groups.

CONCLUSION

TEAS provided analgesic effects in adult patients undergoing major abdominal surgery, and it can be added to clinical practice as a means of accelerating postoperative rehabilitation of these patients.

Research trends from 1992 to 2022 of acupuncture anesthesia: a bibliometric analysis

Background

Acupuncture anesthesia is a significant technical development that originated in China in 1958 and was introduced to the West in the early 1970s. Due to its relative novelty, it has been the subject of intense scrutiny and contestation. Since the early 1970s, the use of acupuncture as a complementary treatment for opioid analgesics has been accepted. Research on acupuncture anesthesia has helped to reduce clinical opioid abuse. However, only a few articles have focused on previous publications that reflect the trend of the study, the main investigators, reciprocal collaboration, and other information in this field. In view of this, we utilized bibliographic analysis methods to objectively analyze current trends and research hotspots in this field, aiming to provide a foundation and reference for future studies.

Methods

The Web of Science database was searched for publications related to acupuncture anesthesia between 1992 and 2022. The CiteSpace and VOSviewer were used to analyze the annual publications, authors, Co-cited authors, and their countries (regions) and institutions, co-occurrence keywords, burst keywords, Co-citation references and Co-citation journals.

Results

A total of 746 eligible publications were retrieved from the database for the analysis, including 637 articles and 109 reviews. And the trend of annual publications continued to grow. Aashish J. Kumar, Daniel I. Sessler, Baoguo Wang, and Paul F. White published the most papers in this field (7), and all authors, had a very low centrality (<0.01). China (252) and the University of California System (21) were the most productive country (region) and institution, respectively, while the United States (0.62) and University of California System (0.16) had the highest centrality. After removing keywords related to the search strategy, the three most frequent were pain (115), electroacupuncture (109), and stimulation (91). The six most recent burst keywords were recovery, transcutaneous electrical acupoint stimulation, systematic review, quality, general anesthesia, and surgery. Wang et al.'s article had the highest co-citation count (20), whereas Zhang et al.'s articles had the highest centrality (0.25). The Journal of Anesthesia and Analgesia was the most influential one (408 co-citations).

Conclusion

This research provides valuable information for the study of acupuncture anesthesia. In recent years, frontier topics in acupuncture anesthesia research have been the promotion of perioperative rehabilitation, anesthesia management, and quality improvement.

Efficacy of acupuncture for pain relief in patients receiving extracorporeal shock wave lithotripsy: a meta-analysis of randomized controlled studies

Background

This meta-analysis aimed at investigating the efficacy of acupuncture for pain relief in patients receiving extracorporeal shock wave lithotripsy (ESWL).

Methods

Randomized controlled trials comparing the efficacy of acupuncture with conventional treatments were retrieved from major electronic databases (e.g., MEDLINE, EMBASE, and Cochrane Library) until August 28, 2022. The primary outcome was the response rate (i.e., rate of pain relief), while secondary outcomes included stone-free rate, satisfaction rate, duration of ESWL, peri-/post-procedural pain score, and risk of adverse events.

Results

Thirteen eligible studies involving 1,220 participants published between 1993 and 2022 were analyzed. Pooled results indicated that acupuncture had a better response rate compared to conventional treatments (RR = 1.17, 95% CI: 1.06-1.3, p = 0.003, seven trials, n = 832). Despite no difference in ESWL duration (MD = 0.02 min, 95% CI: -1.53 to 1.57, p = 0.98, three trials, n = 141), stone-free rate (RR = 1.11, 95% CI: 1-1.25, p = 0.06, six trials, n = 498), and satisfaction rate (RR = 1.51, 95% CI: 0.92-2.47, p = 0.1, three trials, n = 334) between the two groups, the acupuncture group had a lower risk of adverse events (RR = 0.51, 95% CI: 0.33-0.79, p = 0.003, five trials, n = 327), peri- (MD = -1.91 points, 94% CI: -3.53 to -0.28, p = 0.02, four trials, n = 258 patient) and post-procedural (MD = -1.07, 95% CI: -1.77 to -0.36, p = 0.003, four trials, n = 335) pain score.

Conclusion

The results of this meta-analysis showed that the use of acupuncture in patients receiving ESWL was associated with a higher pain relief rate and a lower risk of adverse events, suggesting feasibility of its use in this clinical setting.

Electroacupuncture for Pain Outcomes in a Trauma Center's Acute Pain Service: A Retrospective Observational Study

Background

Evidence for acupuncture to treat pain is growing. Electrostimulation of acupuncture needles (electroacupuncture) is common for pain and is thought to augment the therapeutic effect.

Objectives

To examine the association of pain outcomes after a single acupuncture session with electrostimulation included (EA) compared with no electrostimulation included (NEA).

Methods

A retrospective observational study was conducted using electronic health records of acupuncture sessions for adults with acute pain under the care of an acute pain service. Paired t-test and linear regression were used to report pain intensity changes after a single acupuncture session and by including EA. Ordered logistic regression was used to report categorical pain relief. Logistic regression was used to explore the odds of adding EA and the patient's age, gender, and pretreatment pain.

Results

From July 24, 2017, through November 9, 2020, 465 acupuncture sessions recorded EA (n = 194), or NEA (n = 271). Acupuncture, independent of EA status, reduced pain intensity by a mean 2.5 points. EA was associated with a mean 0.38-point reduction in pain intensity more than NEA (confidence interval [95% CI]: -0.75 to -0.01). Among sessions reporting categorical pain relief (n = 415), higher relief was more likely with EA (odds ratio = 2.16, 95% CI: 1.52-3.08). There was no association between EA and the patient's age, gender, and pretreatment pain intensity.

Conclusions

After a single acupuncture session, both EA and NEA reduced pain intensity. Higher categorical pain relief was reported with EA, though the clinical meaning is uncertain. Future research should focus on well-defined populations for electroacupuncture and factors for including electrostimulation.

The Opioid-Sparing Effect of Acupuncture After Abdominal Surgery: A Systematic Review and Meta-Analysis Protocol

Purpose

Routine overprescribing of postoperative opioid analgesics may induce side effects and correlate with chronic opioid use following surgery. This review aims to evaluate the effectiveness and safety of acupuncture for opioid-sparing effects in patients who underwent abdominal surgery.

Methods

Eleven databases in different languages, including English (Ovid MEDLINE, CENTRAL, EMBASE, CINAHL), Chinese, Korean, and Japanese, will be searched. Randomized controlled trials using acupuncture for postoperative pain control in adult patients undergoing abdominal surgery will be screened. All randomized controlled trials comparing acupuncture with no treatment, sham acupuncture, and conventional treatments will be included. The Cochrane risk of bias tool will be used to assess the risk of bias. The primary outcome will consist of a cumulative opioid consumption. Additionally, the number of cumulative opioid analgesic demands/requests, the time to initial opioid analgesic usage, postoperative pain, opioid-related side effects, and adverse events of acupuncture will be assessed. The mean differences or risk ratios with a 95% confidence interval will be calculated to estimate the pooled effect of acupuncture when it is possible to conduct a meta-analysis.

Results

This study could confirm the effect of opioid-sparing on acupuncture after abdominal surgery.

Conclusion

This study would evaluate the evidence on the effectiveness of acupuncture after abdominal surgery with a focus on opioid intake. It provides evidence to support decision-making on applying acupuncture for postoperative management.

Efficacy and safety of transcutaneous electrical acupoints stimulation for preoperative anxiety in thoracoscopic surgery: study protocol for a randomised controlled trial

INTRODUCTION

Preoperative anxiety occurs at a very high rate in patients undergoing video-assisted thoracoscopic surgery (VATS). Moreover, it will result in poor mental state, more analgesic consumptions, rehabilitation delay and extra hospitalisation costs. Transcutaneous electrical acupoints stimulation (TEAS) is a convenient intervention for pain control and anxiety reduction. Nevertheless, TEAS efficacy of preoperative anxiety in VATS is unknown.

METHODS AND ANALYSIS

This single-centre randomised sham-controlled trial will be conducted in cardiothoracic surgery department of the Yueyang Hospital of Integrated Traditional Chinese and Western Medicine in China. A total of 92 eligible participants with pulmonary nodules (size ≥8 mm) who are arranged for VATS will be randomly assigned to a TEAS group and a sham TEAS (STEAS) group in a 1:1 ratio. Daily TEAS/STEAS intervention will be administered starting on 3 days before the VATS and continued once per day for three consecutive days. The primary outcome will be the generalised anxiety disorder scale score change between the day before surgery with the baseline. The secondary outcomes will include serum concentrations of 5-hydroxytryptamine, norepinephrine and gamma-aminobutyric acid, intraoperative anaesthetic consumption, time to postoperative chest tube removal, postoperative pain, and length of postoperative hospital stay. The adverse events will be recorded for safety evaluation. All data in this trial will be analysed by the SPSS V.21.0 statistical software package.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Ethics Committee of the Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine (approval number: 2021-023). The results of this study will be distributed through peer-reviewed journals.

Integrative Surgery: Embedding Complementary and Nonpharmacologic Therapies into Surgical Pain Management Strategies

There has been a growing interest in the use of complementary and alternative medicine in modern pain management strategies on behalf of both patients and clinicians. Nonpharmacologic modalities such as cryotherapy, acupuncture, music, and mind-body therapies have been shown to aid in symptom control and improve quality of life in patients suffering from acute and chronic pain, and there is a growing body of literature demonstrating their feasibility, acceptability, and efficacy in the perioperative period. Here, we provide a brief review of the current evidence supporting the use of complementary therapies within existing perioperative pain management strategies and highlight evidence-based protocols to facilitate implementation into modern surgical practice.

[Reflexology in patient rehabilitation with postoperative pain. (Literature review)]

Postoperative pain is a pressing medical problem, as it significantly reduces the quality of life of patients after surgical treatment. Chronic postoperative pain further disables patients and impairs their functional activity. Being a widespread interdisciplinary problem, postoperative pain requires the integration of various pain management methods in complex multimodal pain management in the acute period and treatment programs for its chronicity. The paper examines the possibilities of reflexology methods for the relief of acute and treatment of chronic postoperative pain. Integration of reflex effects from the first days after surgery makes it possible to more effectively and safely solve the problems of acute and chronic postoperative pain.

Transcutaneous Electrical Acupoint Stimulation Accelerates the Recovery of Patients Undergoing Laparoscopic Myomectomy: A Randomized Controlled Trial

Purpose

To evaluate transcutaneous electrical acupoint stimulation (TEAS) on the perioperative rehabilitation of patients undergoing laparoscopic myomectomy.

Patients and Methods

One hundred and five women undergoing laparoscopic hysteromyomectomy were randomly divided into TEAS group (Group T) and control group (Group C). Propofol and remifentanil were used to stabilize patient blood pressure and keep BIS between 40 and 60. Group T patients received TEAS at LI4/PC6 30 minutes before the operation and lasting until the end of anesthesia, followed by TEAS at ST36/SP6 for 30 minutes in PACU. All required indicators were recorded.

Results

Group T patients required lower dosages of remifentanil and vasoactive drugs, and had a reduced incidence of propofol injection pain and intraoperative hypotension compared to Group C. Group T also had a lower maximum NRS score in PACU, lower NRS scores at 1 hour and 24 hours, and a lower incidence of vomiting within 24 hours. In addition, the QoR-40 score for Group T at 24 hours after operation was higher in terms of physical comfort, emotional state, pain and total score.

Conclusion

TEAS can reduce the amount of anesthetic, maintain hemodynamic stability, reduce postoperative pain, reduce postoperative vomiting, enhance the recovery of gastrointestinal function, increase the quality of postoperative recovery and thus accelerate overall patient recovery.

Ultrasound-Guided Quadratus Lumborum Block Versus Transversus Abdominis Plane Block for Laparoscopic Inguinal Hernia Repair and Appendicectomy Using Ropivacaine With Dexmedetomidine

Background The present study aims to investigate the efficacy of ultrasound-guided quadratus lumborum (QL) block versus transversus abdominis plane (TAP) block for laparoscopic inguinal hernia repair and appendicectomy using ropivacaine with dexmedetomidine for quality and duration of postoperative analgesia. Settings and design This was a prospective, randomized, single-blind study conducted for one year (September 2020-August 2021) in the Department of Anesthesiology and Critical Care, King George's Medical University, Lucknow, after obtaining ethical clearance from the institutional ethics committee. Methods A total of 64 patients of American Society of Anesthesiologists (ASA) grades I-II and ages between 20 and 50 years undergoing laparoscopic inguinal hernia repair and appendicectomy were randomly allocated into two groups of 32 each; group A received ultrasonography (USG)-guided quadratus lumborum block using 0.5% ropivacaine 20 ml with dexmedetomidine 0.5 mcg/kg of body weight, and group B was given USG-guided transversus abdominis plane block using 0.5% ropivacaine 20 ml with dexmedetomidine 0.5 mcg/kg of body weight after the induction of general anesthesia and before surgical incision. Data were analyzed using Student's t-test, Mann-Whitney U test, and chi-square test as applicable. Results The duration of analgesia was statistically higher (P<0.001) in group A (21.00±3.73 hours) as compared to group B (14.44±2.99 hours). Group A had significantly less analgesic (P<0.001) at 12, 18, and 24 hours postoperatively. The visual analog scale (VAS) was significantly decreased in group A at rest and movement. The range of percentage changes in heart rate (HR) was significantly higher in group B as compared to group A at 12, 18, and 24 hours (group A: 7.23%-14.70%; group B: 6.41%-28.01%). The mean blood pressure (MBP) was significantly increased in group B at 12, 18, and 24 hours as compared to group A. The range of changes in baseline MBP in group A was less than in group B (group A: 0.73%-8.34%; group B: 0.73%-18.20%). Conclusion Quadratus lumborum block is effective and better than transversus abdominis plane block for providing postoperative analgesia during laparoscopic inguinal hernia repair and appendicectomy.

Transcutaneous electrical acupoint stimulation to reduce opioid consumption in patients undergoing inguinal hernia repair: protocol for a randomized controlled trial

BACKGROUND

The purpose of this study is to evaluate the efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) in the postoperative treatment of patients undergoing inguinal hernia repair compared with sham and no treatment group.

METHODS

This study is a protocol for a three-armed, single-blinded, placebo-controlled randomized controlled trial. Ninety participants scheduled for inguinal hernia repair will be randomly assigned to the TEAS group (n = 30), sham group (n = 30), and control group (n = 30). The TEAS group will receive treatment using four portable coin-sized electro-stimulators at both local and distal acupuncture points. The sham group will receive sham treatment with mock electrostimulation. The treatment groups will receive mixed frequency stimulation (alternating at 2 and 100 Hz every 3 s) in continuous mode for 30 min at intervals of 2 h for 24 h postoperatively. The control group will receive postoperative pain control using patient-controlled analgesia (PCA) device. The primary outcome is the total morphine dose received in the postoperative period (mg) using PCA 24 h after surgery. The number of PCA demands (i.e., times the button will be pressed) and delivered bolus doses, score on the Visual Analogue Scale, opioid-related side effects, the requirement for supplemental medications, score on the Hospital Anxiety and Depression Scale (HADS), and blood levels of stress hormones cortisol and prolactin.

DISCUSSION

The results of this trial will determine whether TEAS with intensified stimulation protocol is a safe and effective option for reducing analgesic consumption and postoperative pain.

Acute Pain Management Pearls: A Focused Review for the Hospital Clinician

Acute pain management is a challenging area encountered by inpatient clinicians every day. While patient care is increasingly complex and costly in this realm, the availability of applicable specialists is waning. This narrative review seeks to support diverse hospital-based healthcare providers in refining and updating their acute pain management knowledge base through clinical pearls and point-of-care resources. Practical guidance is provided for the design and adjustment of inpatient multimodal analgesic regimens, including conventional and burgeoning non-opioid and opioid therapies. The importance of customized care plans for patients with preexisting opioid tolerance, chronic pain, or opioid use disorder is emphasized, and current recommendations for inpatient management of associated chronic therapies are discussed. References to best available guidelines and literature are offered for further exploration. Improved clinician attention and more developed skill sets related to acute pain management could significantly benefit hospitalized patient outcomes and healthcare resource utilization.

Acupuncture therapy for radiotherapy-induced adverse effect: A systematic review and network meta-analysis

Objective

To evaluate the efficacy of different acupuncture therapies for radiotherapy-induced adverse effects (RIAEs) and find out the optimal scheme.

Methods

Eligible randomized controlled trials (RCTs) were collected from inception to June 2020 from 9 bibliographic databases. The risk of bias evaluation of the analyzed literature was carried out using the Cochrane risk-of-bias tool. Network meta-analysis was mainly performed using STATA 14.2 and OpenBUGS 3.2.3 by figuring out the network diagrams, league figures, and SUCRA values.

Results

A total of 41 studies with 3,011 participants reported data suitable for network meta-analysis. There was a low to moderate risk of bias in twenty of the articles. ST36 was the most widely prescribed acupoint. Based on network meta-analysis, four outcome indicators were described, namely, acupuncture + medication ranked first in treating radiation enteritis, moxibustion + medication ranked first in preventing radiotherapy-induced leukopenia, acupuncture + medication ranked first in preventing radioactive oral mucositis, and acupuncture ranked first in improving the stimulated salivary flow rate of radioactive xerostomia.

Conclusion

The findings of the network meta-analysis manifested that acupuncture therapy combined with medication has superiority in most RIAEs, both reducing incidence and relieving symptoms. However, high-quality studies are still needed to provide conclusive evidence.

Acupuncture and Spinal Stenosis: Considerations for Treatment

Acupuncture has been a staple of Eastern medicine for thousands of years. Recent evidence has shown that benefits for spinal stenosis are strong. In this comprehensive review, we overview the history and available literature. We discuss how the techniques have evolved and the clinical utility. The process and progression of spinal stenosis is addressed. We discuss mechanism of action for acupuncture as well as relevant treatment implications. This is important in alleviating pain and providing strong quality of life. We highlight both the findings in the pre-operative, peri-operative, and post-operative periods. Finally, the pre-clinical data provides compelling evidence in terms of novel pathways being targeted. This resource will serve as a user-friendly guide for the clinician and scientist regarding this important topic. It will be the catalyst of ongoing investigation from both the clinical and pre-clinical side.

Non-pharmaceutical treatments to relieve pain or reduce opioid analgesic intake and improve quality of life after total hip replacement: a meta analysis

To reduce pain after total hip replacement (THR), researchers are interested in drug-free interventions. However, there is still a lack of consensus on their prevention efficacy. We performed a meta-analysis to evaluate the use of nonpharmaceutical interventions for postoperative pain management after THR. We searched the Cochrane Library, MEDLINE, EMBASE, Web of Science, PEDRO, and ClinicalTrials.gov databases for articles published between and 1991 and 2020. The main outcome measures were postoperative pain, opioid consumption, and quality of life (QoL). In total, 1,942 patients were studied. We found moderate evidence indicating postoperative pain relief measured by the Western Ontario and McMaster Universities Arthritis Index Scale, with mean differences (MDs) of -0.28 (95% confidence interval [CI], -0.49 to -0.07; P=0.01; I² =0%) within three months, -0.19 (95% CI, -0.40 to 0.02; P=0.07; I² =0%) between 3-6 months, and -0.13 (95% CI, -0.35 to 0.08; P=0.21; I² =0%) between 6-12 months. Additionally, we found that acupuncture therapy could reduce opioid analgesic consumption (MD, -0.98; 95% CI, -1.18 to -0.79; fentanyl [mg/h]; P<0.01; I² =72.2%) and significantly improve pain relief with an MD of 0.90 (95% CI, 0.47 to 1.33; P<0.01; I² =0%) measured using the visual analog scale. Electrotherapy slightly improved perceived pain with an MD of 0.22 (95% CI, -0.27 to 0.70; P=0.37; I² =0%). Moreover, moderate evidence has shown that preoperative exercises improve QoL. This meta-analysis suggested that continuous passive motion did not improve pain or QoL. Postoperative exercise was associated with pain relief and improved QoL. Acupuncture therapy after THR has been shown to reduce opioid analgesic consumption.

Complementary medicine usage in surgery: a cross-sectional survey in Germany

Background

Complementary medicine (CM) is frequently used by patients, but little is known about the usage of CM in surgical patients. The study aimed to elucidate the relevance of CM in surgery.

Methods

This cross-sectional, multi-center survey utilized a paper-based questionnaire consisting of 21 questions to capture CM usage and interest as well as CM communication in visceral and thoracic surgical patients being hospitalized at the corresponding departments of surgery at the University Medical Centers in Freiburg, Heidelberg und Ulm, Germany.

Results

Overall, 151 patients consented to the survey. On average, current CM usage was stated by 44% of patients. Most frequently used CM approaches were physical exercise (63%), nutritional supplements (59%) and herbal medicine (56%). Strong interest in CM counselling was stated by 51% of patients. Almost 80% of patients wanted to be treated in a holistic manner and desired for reliable information about CM as well as CM informed physicians. Only 12% of patients communicated CM usage and interest with their attending physician. Review of literature revealed similar results showing an overall CM usage of 43%, preferring nutritional supplements and herbal medicine.

Conclusion

The results of our cross-sectional study indicate a high percentage of CM users and a strong interest in CM among surgical patients. Indeed, the current communication about CM between patients and surgeons is poor. With respect to safety and quality reasons, but also to pay attention to patients’ demands, physicians should be aware of patients’ CM usage in surgery.

Acupuncture for pain control after degenerative lumbar spine surgery

Background

Wound pain after surgery for lumbar spine disease may interfere with patients’ recovery. Acupuncture is commonly used for pain management, but its efficacy for postoperative pain control is unclear. This study aimed to evaluate the effectiveness of acupuncture for adjuvant pain control after surgery for degenerative lumbar spine disease.

Methods

We retrospectively reviewed the records of consecutive patients who received surgery for degenerative lumbar spine disease at our institution from 2013 to 2014. Surgical procedures included open laminectomy, discectomy, and trans-pedicle screw instrumentation with posterior-lateral fusion. Patients were grouped by pain control methods, including routine analgesia, patient-controlled analgesia (PCA), and acupuncture. The routine analgesia group received oral acetaminophen/non-steroidal anti-inflammatory drugs with meperidine as needed for immediate pain control. The PCA group received a basal dose of morphine and subsequent user-demand doses. The acupuncture group received acupuncture every other day after surgery.

Results

Ninety-six patients were included, of whom 37 received acupuncture, 27 received PCA, and 32 received routine analgesics for pain control. Visual analog scale (VAS) pain scores in all 3 groups decreased significantly, and to the same degree, from the first postoperative day to the second day. No significant differences were found in VAS scores over the next 6 postoperative days; however, the scores of patients treated with PCA were slightly but still significantly higher (p = 0.026) on postoperative day 4 than scores of patients treated with acupuncture and traditional analgesia, a difference likely due to PCA being discontinued on postoperative day 3. No major complications were noted in the acupuncture group, but 2 patients dropped out because of fear of needle insertion.

Conclusions

Acupuncture may be as effective as traditional analgesia and PCA for adjuvant pain control after surgery for degenerative lumbar spine disease.

Acupuncture Analgesia in Patients with Postoperative Neck Pain: A Protocol for Systematic Review and Meta-Analysis

Background. There is a yearly increase in pain after neck surgery, which is accompanied by high consumption of opioids. However, the opioid addiction epidemic is one of the most serious public health problems worldwide. Therefore, it is important to find suitable alternatives for opioids. Acupuncture therapy has been found effective for some types of pain control. This protocol aims to evaluate the efficacy and safety of acupuncture therapy in the treatment of pain after neck surgery. Methods and Analysis. We will search eight electronic databases from their inception to April 2022. Only randomized controlled trials (RCTs) using manual acupuncture, auricular acupuncture, or electroacupuncture as major therapy will be included, regardless of whether the study was published in Chinese or English. The selection of studies and data extraction will be independently completed by at least two experienced reviewers with a master's degree. The methodological quality of the included studies will be assessed by the Cochrane risk-of-bias tool. For the meta-analysis, Review Manager Statistical (RevMan V.5.3) software will be used. The results will be presented as the risk ratio (RR) for the binary data and the mean difference (MD) or standardized mean difference (SMD) for the continuous data. Ethics and Dissemination. This protocol for a systematic review will be submitted to a peer-reviewed journal for publication and presented at a relevant conference, and there is no need to obtain formal ethical approval.

Acupuncture intervention for acute pain in the Emergency Department trial: a consensus process

PURPOSE

This document describes the consensus process and intervention for a National Institutes of Health (NIH)-funded multi-site feasibility study utilizing acupuncture for ACUte paIn in The EmergencY Department (ACUITY). The acupuncture intervention is designed to be flexible and responsive to the most common Emergency Department (ED) scenarios, including trauma, acute pain of the low back, abdomen and/or musculoskeletal system, renal colic and headache.

BACKGROUND

Opioids remain a primary treatment for acute ED pain with attendant risk of adverse effects, addiction liability, diversion and death. Effective/safer options for acute pain are needed. Although acupuncture therapy has shown promise for acute pain in the ED alone or in conjunction with usual care, pragmatic trials are needed to obtain definitive and generalizable evidence.

METHODS

An Acupuncture Advisory Panel was convened that included nine acupuncture experts with 5-44 years of experience in practice and 2-16 years of experience in the acute pain care setting. A modified Delphi process was used with provision of a literature review, surveys of our panel members, three online discussions and email discussion as needed. The STandards for Reporting Interventions in Controlled Trials (STRICTA) checklist was used as a guide.

RESULTS

A responsive acupuncture intervention was agreed on for ACUITY. Session forms were fashioned in REDCap (Research Electronic Data Capture program to capture essential treatment data, assess fidelity and inform our design for a future pragmatic multi-site randomized controlled trial (RCT) of acupuncture in the ED, and for use by other future researchers.

CONCLUSION

Development of a responsive manualization intervention provides the appropriate framework for conducting a future, pragmatic, multi-site, definitive RCT of acupuncture in the ED.

The effectiveness of acupuncture point stimulation for the prevention of postoperative sore throat: A meta-analysis

BACKGROUND

Enhanced recovery pathways can be further improved for postoperative sore throat (POST) that occurs after surgery under general anesthesia. Medications have shown some effectiveness in preventing POST, but acupuncture or related techniques with better safety and lower cost can be used as an alternative or adjuvant therapy to treat perioperative symptoms by stimulating acupuncture point (acupoint). Therefore, we aimed to conduct a meta-analysis to assess whether acupoint stimulation helps patients prevent POST in adults undergoing tracheal intubation for general anesthesia.

METHODS

Publications in PubMed, the Cochrane Central Register, ScienceDirect, and ClinicalTrial.gov were surveyed from January 2000 through August 2020. Studies that compared interventions between true acupoint stimulation and no or sham acupoint stimulation were included. The primary outcomes were the incidence and severity of POST at 24h.

RESULTS

Four randomized control trials and 1 comparative study involving 1478 participants were included. Compared with the no or sham acupoint stimulation, the true acupoint stimulation was associated with a reduced incidence (risk ratio, 0.32; 95% confidence interval (CI), 0.18-0.55; P < .001) and decreased severity (standardized mean difference, -2.79; 95% CI, -4.59 to - 0.99; P = .002) of POST. There were no significant adverse events related to acupoint stimulation. The finding for POST was assured by subgroup, sensitivity, and trial sequential analyses.

CONCLUSIONS

Acupoint stimulation may reduce the occurrence of POST. It can be considered as one of nonpharmacological methods to prevent POST in enhanced recovery pathways. Further rigorous studies are needed to determine the effectiveness of acupoint stimulation.

Low-level laser acupuncture reduces postoperative pain and morphine consumption in older patients with total knee arthroplasty: A randomized placebo-controlled trial

BACKGROUND

Patients commonly develop postoperative pain after total knee arthroplasty (TKA). Acupuncture-related techniques and low-level laser therapy could be beneficial for pain management for older individuals.

OBJECTIVE

To examine the effect of low-level laser acupuncture (LA) in reducing postoperative pain, pain-related interference in daily life, morphine consumption, and morphine-related side effects in older patients with knee osteoarthritis who underwent TKA.

DESIGN, SETTING, PARTICIPANTS AND INTERVENTION

A single-blind randomized placebo-controlled trial was conducted. Patients (N = 82) were recruited and randomly assigned via a computer-generated list to the LA group or a placebo group. The LA group received low-level laser therapy at Sanyinjiao (SP6), Taixi (KI3), Kunlun (BL60), Fengshi (GB31), Futu (ST32) and Neiguan (PC6) after TKA, while the placebo acupuncture group received the same treatment procedure without laser energy output.

MAIN OUTCOME MEASURES

The primary outcome was postoperative pain intensity, and it was measured at baseline and hours 2, 6, 10, 24, 48 and 72 after TKA. The secondary outcomes, including relative pain, postoperative pain-related interference in daily life and morphine consumption, were measured at hours 24, 48 and 72 after TKA.

RESULTS

Generalized estimating equations revealed significant between-group differences in pain intensity (P = 0.01), and trend differences in pain intensity for the LA group starting at hours 10 to 72 (P < 0.05) and morphine consumption at hours 48 and 72 (P < 0.05). The changes in pain-related interference in daily life were significant (P < 0.05) at 72 h, with the exception of the parameters for worst pain, mood, and sleep. Nausea and vomiting side effects from morphine had significant between-group differences at hours 10 and 24 (P < 0.05).

CONCLUSION

Low-level LA gradually reduced older patients' postoperative pain intensity and morphine consumption within the first 72 h after their TKA for osteoarthritis. Low-level LA may have benefits as an adjuvant pain management technique for clinical care.

Purpose

The purpose of this study is to analyze and visualize the research trends on acupuncture therapy for postoperative pain over the past 20 years to identify hotspots and frontiers, and provide new research ideas.

Methods

A search of the Web of Science database, with a time frame of 2001–01-01 to 2022–02-28, was conducted to collect literatures related to acupuncture therapy for postoperative pain. A bibliometric analysis and visualization of results was performed using CiteSpace software for the volume of annual publications, journals, countries, institutions, authors, keywords, and references.

Results

A total of 840 literatures were eventually included in the analysis. The number of publications has fluctuated upwards each year over the past 20 years and reached a peak in the latest three years. Evidence-Based Complementary and Alternative Medicine was the journal with the most relevant publications and Pain was the most frequently cited journal. The country with the highest volume of publications was China, and the USA contributed most to the international collaboration. The most prolific and influential authors were Inhyunk Ha and Han JS respectively. The most frequent keyword was “acupuncture”. References with highest frequency or centrality were both systematic evaluations focusing on different acupuncture therapies for postoperative pain relief.

Conclusion

The field of acupuncture therapy for postoperative pain is currently in a period of high growth. China and the USA have made the largest contribution to the volume of publications. The most influential institutions and authors are mainly from China and South Korea. The overall collaborative network needs to be strengthened. Electroacupuncture and auricular acupuncture (therapeutic techniques), low back surgery (types of surgery), and “postoperative pain, nausea and vomiting” are research hotspots in this field. Improvement of postoperative life quality, proof of clinical efficacy and evidence-based evaluation are the current research trends and frontiers.

Using a consensus acupoints regimen to explore the relationship between acupuncture sensation and lumbar spinal postoperative analgesia: A retrospective analysis of prospective clinical cooperation

OBJECTIVE

This study evaluated the effectiveness of acupuncture treatment on postoperative pain in patients with degenerative lumbar spine disease, and explored the relationship between the postoperative analgesic effect of acupuncture and the sensation of acupuncture experienced by the patients.

METHODS

This retrospective study analyzed the medical records of 97 patients who had undergone an operation by the same surgeon due to degenerative lumbar disease. These patients were divided into acupuncture group (n = 32), patient-controlled analgesia (PCA) group (n = 27), and oral analgesia group (n = 38) according to the different postoperative analgesic methods. During their hospitalization, patients completed daily evaluations of their pain using a visual analogue scale (VAS), and injection times of supplemental meperidine were recorded. Also, the Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) was used in the acupuncture group.

RESULTS

Each of the three treatment groups showed significant reductions in postoperative pain, as shown by reduced VAS scores. The acupuncture group, however, had less rebound pain (P < 0.05) than the other two groups. Both the acupuncture and PCA groups experienced acute analgesic effects that were superior to those in the oral analgesia group. In addition, the higher the C-MASS index on the second day after surgery, the lower the VAS score on the fourth day after surgery. There was also a significant difference in the "dull pain" in the acupuncture sensation.

CONCLUSION

The results demonstrated that acupuncture was beneficial for postoperative pain and discomfort after simple surgery for degenerative spinal disease. It is worth noting that there was a disproportionate relevance between the patient's acupuncture sensation and the improvement of pain VAS score.

Acupuncture Analgesia in Patients With Traumatic Rib Fractures: A Randomized-Controlled Trial

Pain management for traumatic rib fracture is important to prevent complications and reduce associated comorbidities. This trial investigated the analgesic efficacy of acupuncture on traumatic rib fracture. Patients with traumatic rib fracture were randomly assigned to traditional acupuncture (TA), laser acupuncture (LA) or sham laser acupuncture (SLA) groups in a 1:1:1 ratio. The intervention was performed on days 1 to 3 after treatment allocation. The acupoints included bilateral LI4 (Hegu), SJ6 (Zhigou), ST36 (Zusanli) and GB34 (Yanglingquan). The primary outcome was Numeric Rating Scale (NRS) scores for pain after the intervention. Secondary outcomes included sustained maximal inspiration (SMI) lung volume, stress responses, the use of analgesics, and associated complications. Data were analyzed via one-way analysis of variance (ANOVA) with Scheffé's post hoc testing or chi-squared testing. Of the 120 study participants, 109 completed all interventions and measurements. The primary outcomes, which indicated average pain intensity levels and pain while deep breathing, were both significantly lower in the TA and LA groups than in the SLA group after 2 treatments. No between-group differences were observed in SMI lung volume, stress response, analgesics use or associated complications. These findings suggest that TA and LA are safe and effective analgesic modalities for pain management for traumatic rib fracture.

Additional Benefit of Intraoperative Electroacupuncture in Improving Tolerance of Deep Brain Stimulation Surgical Procedure in Parkinsonian Patients

Background: Deep brain stimulation (DBS) is an effective technique to treat patients with advanced Parkinson’s disease. The surgical procedure of DBS implantation is generally performed under local anesthesia due to the need for intraoperative clinical testing. However, this procedure is long (5–7 h on average) and, therefore, the objective that the patient remains co-operative and tolerates the intervention well is a real challenge. Objective: To evaluate the additional benefit of electroacupuncture (EA) performed intraoperatively to improve the comfort of parkinsonian patients during surgical DBS implantation. Methods: This single-center randomized study compared two groups of patients. In the first group, DBS implantation was performed under local anesthesia alone, while the second group received EA in addition. The patients were evaluated preoperatively, during the different stages of the surgery, and 2 days after surgery, using the 9-item Edmonton Symptom Assessment System (ESAS), including a total sum score and physical and emotional subscores. Results: The data of nine patients were analyzed in each group. Although pain and tiredness increased in both groups after placement of the stereotactic frame, the ESAS item “lack of appetite”, as well as the ESAS total score and physical subscore increased after completion of the first burr hole until the end of the surgical procedure in the control group only. ESAS total score and physical subscore were significantly higher at the end of the intervention in the control group compared to the EA group. After the surgical intervention (D2), anxiety and ESAS emotional subscore were improved in both groups, but the feeling of wellbeing improved in the EA group only. Finally, one patient developed delirium during the intervention and none in the EA group. Discussion: This study shows that intraoperative electroacupuncture significantly improves the tolerance of DBS surgery in parkinsonian patients. This easy-to-perform procedure could be fruitfully added in clinical practice.

Acupuncture and Postoperative Pain Reduction

PURPOSE OF REVIEW

Acupuncture is an analgesic technique that has long been utilized in Eastern medicine. In recent times, various acupuncture techniques have been used in integrated pain management approaches in Western medicine. It has even been adopted as an analgesic method in surgical patients. Currently, no review exists regarding various acupuncture techniques used in perioperative pain management and data describing the utility of these techniques. This paper synthesizes the latest literature regarding the role of acupuncture in perioperative pain management. The authors sought to describe various acupuncture modalities used to help manage surgical pain and synthesize the current body of literature to help readers make informed judgements on the topic.

RECENT FINDINGS

Patients undergoing abdominal, spine/neuro, and gynecologic pelvic surgery generally benefit from acupuncture. Out of the various acupuncture techniques, electroacupuncture, transcutaneous electric acupoint stimulation, and traditional total body acupuncture seem to be most promising as adjuncts to multimodal perioperative analgesia. Benefits include improved analgesia and/or reduced narcotic requirements, decrease in PONV, and shorter time to return of bowel function. Acupuncture is a low-risk method that has the potential to enhance perioperative analgesia, decrease opioid requirement, and reduce unwanted side effects of anesthesia, surgery, and opioid administration such as nausea/vomiting. Given the variety of patient populations, various acupuncture techniques, and small patient populations for most current studies; it remains difficult to determine which acupuncture method would most benefit specific patients. Future studies with more robust sample sizes and prospective comparison on acupuncture technique would help better characterize acupuncture's role in perioperative pain management.

Effect of electroacupuncture on discomfort during gastroscopy: a study protocol for a randomized controlled trial

Background

Gastroscopy procedures are frequently performed under general sedation to minimize discomfort. Patients who refuse a sedative injection may experience more discomfort and adverse reactions such as pain and nausea. These instances reduce patient compliance and willingness to participate in future procedures. Acupuncture has been shown to have an anti-nausea and analgesic effect; however, there is limited data available that demonstrates the efficacy of acupuncture when applied before gastroscopy.

Methods

A total of 60 participants will be randomly assigned to the electroacupuncture (EA) group and the sham electroacupuncture (SEA) group at a ratio of 1:1. Acupuncture treatment will be performed before gastroscopy for a duration of 30 min. All patients will complete detailed questionnaires at 30 min and 7 days post-procedure to record the severity of their symptoms. The primary outcome will be the average of 4 standard visual analogue scale (VAS) scores in the categories of nausea, vomiting, throat discomfort, and agitation as reported by the patient. The secondary outcomes will be patient’s anxiety level as recorded by the 6-item short form of the State-Trait Anxiety Inventory (STAI-S6) and Amsterdam Pre-Operative Anxiety and Information Scale (APAIS), preference in a future endoscopy, pulse oxygen saturation (SpO2), heart rate (HR), and blood pressure (BP). Anxiety scales will be assessed before and after acupuncture; others will be completed at 30 min and 7 days post-procedure. The duration of the gastroscopy and the number of biopsies will be recorded after operation.

Discussion

This randomized controlled trial will explore the feasibility of the further clinical application of electroacupuncture for the improvement of patient discomfort during gastroscopy without systemic sedation.

Acupuncture therapy as an Evidence-Based Nonpharmacologic Strategy for Comprehensive Acute Pain Care: the Academic Consortium Pain Task Force White Paper Update

Background

A crisis in pain management persists, as does the epidemic of opioid overdose deaths, addiction, and diversion. Pain medicine is meeting these challenges by returning to its origins: the Bonica model of multidisciplinary pain care. The 2018 Academic Consortium White Paper detailed the historical context and magnitude of the pain crisis and the evidence base for nonpharmacologic strategies. More than 50% of chronic opioid use begins in the acute pain care setting. Acupuncture may be able to reduce this risk.

Objective

This article updates the evidence base for acupuncture therapy for acute pain with a review of systematic reviews and meta-analyses on postsurgical/perioperative pain with opioid sparing and acute nonsurgical/trauma pain, including acute pain in the emergency department.

Methods

To update reviews cited in the 2018 White Paper, electronic searches were conducted in PubMed, MEDLINE, CINAHL, and the Cochrane Central Register of Controlled Trials for “acupuncture” and “acupuncture therapy” and “acute pain,” “surgery,” “peri-operative,” “trauma,” “emergency department,” “urgent care,” “review(s) ,” “systematic review,” “meta-analysis,” with additional manual review of titles, links, and reference lists.

Results

There are 22 systematic reviews, 17 with meta-analyses of acupuncture in acute pain settings, and a review for acute pain in the intensive care unit. There are additional studies of acupuncture in acute pain settings.

Conclusion

The majority of reviews found acupuncture therapy to be an efficacious strategy for acute pain, with potential to avoid or reduce opioid reliance. Future multicenter trials are needed to clarify the dosage and generalizability of acupuncture for acute pain in the emergency department. With an extremely low risk profile, acupuncture therapy is an important strategy in comprehensive acute pain care.

Patient Attitudes Toward Acupuncture in the Perioperative Setting

Introduction: Acupuncture is a potential treatment option for pain, nausea, vomiting, anxiety, and agitation in the perioperative period. Patient preference for participating in acupuncture in the perioperative period is not well understood. The aim of this study was to quantify patient interest in perioperative acupuncture, explore the relationship between acupuncture interest, insurance coverage and patient cost, and identify clinical factors associated with patient interest in acupuncture. Materials and Methods: Adult patients evaluated in the Preoperative Evaluation Clinic at the Mayo Clinic in Phoenix, AZ, between June 2019 and July 2019, received a voluntary survey to assess their attitudes toward receiving acupuncture in the perioperative period. Patient interest in acupuncture to help treat pain, anxiety, and postoperative nausea and vomiting, as well as their willingness to pay for such services, were assessed. Demographic data, American Society of Anesthesiologists (ASA) physical class, scheduled procedure, and insurance coverage were extracted from the medical record. Univariate analysis was performed to estimate interest in acupuncture. Results: Three hundred and seven respondents were included in this study with a response rate of 60.4%. A total of 68.4% of study participants were interested in receiving perioperative acupuncture. Of those interested in acupuncture, 86.7% were interested if acupuncture was offered at no cost (either free or fully covered by insurance). A total of 47.1% of those patients interested in acupuncture would be interested if the cost of acupuncture was between 20 and 50 U.S. dollars. A total of 8.6% would be interested in acupuncture if patients were expected to pay the full cost of treatment (estimated 175 U.S. dollars). Age, sex, ASA status, type of surgery, risk of procedure, and Medicare/Medicaid coverage were not statistically associated with interest in acupuncture. Conclusions: When there is little to no direct cost to the patient, the majority of patients are interested in acupuncture in the perioperative period.

The Role of Acupuncture in Relieving Post-Hemorrhoidectomy Pain: A Systematic Review of Randomized Controlled Trials

Background

Post-hemorrhoidectomy pain (PHP) remains one of the complications of hemorrhoidectomy and can delay patient's recovery. Current clinical guideline on PHP remains skeptical on the effectiveness of acupuncture, which has been applied for PHP in practice with inconsistent evidence.

Objectives

This systematic review aimed to evaluate the effectiveness of acupuncture on PHP by reviewing existing evidence.

Methods

Nine databases such as PubMed and Embase were searched for randomized controlled trials (RCTs) from inception to 30th September 2021. The outcome measures on pain level after hemorrhoidectomy, dose of rescue analgesic drug used, quality of life, adverse events, etc., were extracted and analyzed in a narrative approach.

Results

Four RCTs involving 275 patients were included in the analysis. One study showed that the visual analog scale (VAS) score was significantly lower in the electro-acupuncture (EA) group compared to that in the sham acupuncture (SA) group at 6, 24 h after surgery and during the first defecation (p < 0.05). Similar trends were found in the verbal rating scale (VRS) and Wong-Baker Faces scale (WBS) score but at different time points. Another study also found EA was effective on relieving pain during defecation up to 7 days after surgery when compared with local anesthetics (p < 0.05). However, two studies evaluating manual acupuncture (MA) compared with active medications for PHP showed inconsistent results on effectiveness. Variability was found in the quality of included studies.

Conclusions

Although benefit of acupuncture on PHP, especially EA on defecation after surgery, was observed at some time points, evidence on effectiveness of acupuncture on PHP was not conclusive.

Understandings of acupuncture application and mechanisms

Acupuncture involves the stimulation of acupoints, which are located at specific sites of the human body, by insertion of fine metal needles, followed by manipulation. Acupuncture has been proven to be an effective treatment in pain relief. Available evidence showed that acupuncture alleviates acute pain in conditions such as postoperative pain, acute back pain, labour pain, primary dysmenorrhea, tension-type headaches and migraines. In addition, acupuncture relieves chronic pain, for example, low back pain (LBP), knee osteoarthritis (KOA), headache, shoulder pain, and neck pain. For other diseases like insomnia, drug addiction and stroke, more high-quality randomized control trials (RCTs) are needed to confirm the efficacy of acupuncture, although there are particular difficulties surrounding adequate blinding and control group designs. Recent biomedical technology unveils the mechanisms of acupuncture. Studies have found that adenosine triphosphate (ATP) and transient receptor potential vanilloid (TRPV) channels are involved in the stimulation of acupuncture at the acupoint area. In the central nervous system (CNS), neurotransmissions including opioids, serotonin, norepinephrine, orexin and endocannabinoid are modulated by acupuncture to induce analgesia. Moreover, acupuncture reduces cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) levels on the peripheral level by acting on the hypothalamic-pituitary-adrenal (HPA) axis, mediating peripheral opioid release. Acupuncture helps to treat insomnia by inhibiting sympathetic activity and down-regulating the HPA axis. Additionally, acupuncture reduces the effects of positive and negative reinforcements by modulating dopamine release in the nucleus accumbens. Recently, i-needles have been developed to allow for the analysis of metagenomics, meta-transcriptomics, and host-microbiome relationships following acupuncture, while skin implantable microsensors or needle-shaped microsensors are feasible for monitoring real-time microenvironmental changes in acupoints and even target organs. These studies may further accelerate the understanding of acupuncture's action mechanism.

Effect of Inpatient Integrative Medicine Consultation on 30-Day Readmission Rates: A Retrospective Observational Study at a Major U.S. Academic Hospital

Objectives: The prevalence of inpatient integrative medicine (IM) consult services is increasing among academic health care institutions. The diversity of services between institutions, as well as the novel nature of such interventions, makes it challenging for health care administrators to determine the cost/benefit of adding such a program to their institution. The main purpose of this study was to examine the performance of the new University of California, Los Angeles (UCLA) East-West (EW) consult service as measured by 30-day readmission rates and lengths of stay. Design: This is a retrospective observational case-control study with participants matched to themselves. Setting: UCLA Santa Monica Hospital, a 281-bed academic tertiary care hospital near Los Angeles, California. Subjects: Patients who had received an EW consultation during the inaugural 20 months of the program (2018-2020), and who had been hospitalized in the prior 2 years from the date of their first EW consult. Intervention: Inpatient East-West consultation, which may include counseling, acupuncture and/or trigger point injections depending on medical necessity. Outcome Measures: Thirty-day readmission rates and lengths of hospital admission were compared between the hospitalization that included an EW consult (which included the use of acupuncture and/or trigger point injections when appropriate) and any prior admissions during the 2 years before that EW consult. Secondary outcomes included quantitative analysis of average number of treatments and qualitative assessment of integrative treatment(s) received, conditions treated, and reasons that EW treatment may have been deferred during a consult. Results: One hundred sixty-five unique patients met the study criteria. The EW consultation was associated with clinically relevant, statistically significant decreased 30-day readmission rates (33.0% vs. 4.6%, p < 0.001, odds ratio [OR] 0.10, 95% confidence interval [CI] 0.06-0.17). This effect was similar when limiting the analysis to pain-related admissions (32.3% vs. 3.4%, p < 0.001, OR = 0.07, 95% CI 0.03-0.16). Hospital admissions with EW consults were found to have a statistically significant increased length of stay (7.03 days vs. 5.40 days, p < 0.001). Conclusion: The EW medicine, an example of IM, correlates with a reduced risk of 30-day readmission and with modestly increased lengths of stay.
