Effects of Acupuncture in Anesthesia for Craniotomy: A Meta-Analysis

Research hotspots and trends on acupuncture therapy on vomiting from 1990 to 2022: A bibliometric analysis

OBJECTIVES

Acupuncture treatment (AT) is commonly utilized for vomiting; however, limited bibliometric analyses exist in this area. Employing a bibliometric approach, we conducted a comprehensive review spanning three decades to assess the research landscape, advancements, and emerging trends in AT for vomiting.

METHODS

We collected the related literature data from the Web of Science Core Collection (WOSCC) from 1990 to 2022. VOSviewer and R studio were used to perform the bibliometric analysis of AT on vomiting. The status of authors, countries, affiliations, annual publications, keywords, and journals were analyzed accordingly.

RESULTS

The earliest relevant paper was published in 1990. Streitberger, K was the most productive author (7 records) and had significant influence (225 reference times, H-Index = 7). The United States had the highest publication count (224 records) and received the most recognition (9719 reference times, H-Index = 52). MEDICINE had the highest number of outputs (34 records), while ANESTHESIA AND ANALGESIA was the most cited journal (1045 reference times). The institution with the most works was Chengdu University of Traditional Chinese Medicine (CDUTCM) (13 records), and the University of California, Los Angeles received the most citations (1252 reference times). Recent and future research hotspots included AT for postoperative vomiting and post-chemotherapy vomiting. Systematic reviews and meta-analyses were the predominant study types.

CONCLUSIONS

The current status and development prospects of AT for vomiting are shown in this study. In addition, this article provides valuable ideas and potential directions for future research activities.

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.

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.

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.

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.

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.

Transcutaneous Electrical Acupoint Stimulation for the Prevention of Postoperative Cognitive Dysfunction: A Systematic Review and Meta-Analysis

Background: No specific treatment is available for postoperative cognitive dysfunction (POCD). Recently, interest in the prevention of POCD during the perioperative period has increased. Although some studies suggest that transcutaneous electrical acupoint stimulation (TEAS) may be beneficial, the relevant evidence remains uncertain. Objective: To evaluate the preventive effects of TEAS on POCD. Methods: Seven databases including PubMed, EMBASE, CENTRAL, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), Wanfang Database, and Chinese Biomedical Literature Database (CBM) were electronically searched up to April 2021. Two reviewers independently selected the studies, collected data, and assessed the risks of bias and grading of recommendations, assessment, development, and evaluations certainty of the evidence. A meta-analysis of the incidence of POCD, cognitive function score, pain, adverse reactions, and length of hospital stay after surgery was also performed. Results: Twenty-nine randomized controlled trials with 1,994 participants were included. The results of the meta-analysis showed that the TEAS group has a significantly lower incidence of POCD compared with the control group on postoperative days 1 [OR = 0.33 (95%CI: 0.23, 0.47); p < 0.001, I ² = 0%, moderate certainty], 3 [OR = 0.38 (95%CI: 0.29, 0.50); p < 0.001, I ² = 0%, low certainty], and 7 [OR = 0.51 (95%CI: 0.32, 0.81); p = 0.005, I ² = 0%, low certainty] but not on day 5 (p > 0.05, low certainty). Moreover, TEAS improved the Mini-Mental State Examination scores on postoperative days 1, 3, and 7 [MD = 2.44 (95%CI: 1.61, 3.27); p < 0.001, I ² = 93%, low certainty]; [MD = 2.07 (95%CI: 1.53, 2.62); p < 0.001, I ² = 87%, low certainty]; and [MD = 0.49 (95%CI: 0.18, 0.79); p = 0.002, I ² = 21%, low certainty], respectively, but not on day 5 (p > 0.05, very low certainty). TEAS promoted a postoperative analgesic effect within 24 h after surgery. Furthermore, patients receiving TEAS showed a lower incidence of postoperative nausea and vomiting and a shorter hospital stay. Conclusions: Limited evidence suggests that the application of TEAS in the perioperative period is associated with a reduced POCD rate and a protected early postoperative cognitive function.

Transcutaneous electrical acupoint stimulation combined with electroacupuncture for rapid recovery of patients after laparotomy for gastrointestinal surgery: a study protocol for a randomised controlled trial

INTRODUCTION

Abdominal surgery is associated with common complications, including decreased or poor appetite, abdominal distension, abdominal pain caused by decreased or absent gastrointestinal motility, anal arrest with flatus and defecation, and nausea and vomiting resulting from the use of anaesthetics and opioid analgesics. These complications seriously affect postoperative recovery, prolong hospital stay and aggravate patient burden. This study aims to investigate for the first time the efficacy of transcutaneous electrical acupoint stimulation (TEAS) combined with electroacupuncture (EA) therapy for rapid recovery after laparotomy for gastrointestinal surgery. There have been no clinical studies of this combination therapy.

METHODS AND ANALYSIS

This will be a prospective, single-centre, three-arm, randomised controlled trial. A total of 480 patients undergoing abdominal surgery will be stratified according to surgery type (ie, gastric or colorectal procedure) and randomised into three groups; namely, the EA, TEAS +EA and control groups. The control group will receive enhanced recovery after surgery (ERAS)-standardised perioperative management, including preoperative education, optimising the anaesthesia scheme, avoiding intraoperative hypothermia, restrictive fluid infusion and reducing surgical trauma. The EA group will receive EA stimulation at LI4, PC6, ST36, ST37 and ST39 based on the ERAS-standardised perioperative management. Moreover, the TEAS +EA group will receive ERAS-standardised perioperative management; EA stimulation at the LI4, PC6, ST36, ST37 and ST39; and TEAS stimulation at ST21 and SP15. The primary outcome will be the GI-2 (composite outcome of time to first defaecation and time to tolerance of a solid diet). Secondary outcomes will include the time of first passage of flatus, time to first defaecation, time to tolerance of a solid diet, time to first ambulation, hospital duration from operation to discharge, pain and nausea vomiting scores on the Visual Analogue Scale, medication use, incidence of postoperative complications and evaluation of treatment modality acceptability. All statistical analyses will be performed based on the intention-to-treat principle.

ETHICS AND DISSEMINATION

Ethics approval has been granted by the Ethics Committee on Biomedical Research, West China Hospital of Sichuan University (approval number: 2021; number 52). The results are expected to be published in peer-reviewed journals.

Postoperative Nausea and Vomiting After Craniotomy: An Evidence-based Review of General Considerations, Risk Factors, and Management

One of the most common and distressing symptoms after craniotomy is postoperative nausea and vomiting (PONV). PONV could generate delayed postanesthesia care and hospitalization discharge, lower patient satisfaction, and an increase in overall hospitalization costs. The incidence of reported PONV after craniotomy is 22% to 70% without prophylaxis, and a multimodal regimen of medication has been recommended. We conducted a comprehensive literature review of the clinical evidence related to PONV prevention and management after craniotomy. All clinical trials in adult populations relevant to PONV after craniotomy available in English language and indexed in PubMed, Google Scholar and Cochrane Library databases from January 1997 up to September 2018 were retrieved using a combination of free-text words related to PONV in craniotomy. After screening manuscripts identified in the initial search, 23 clinical trials investigating systemic pharmacological intervention versus placebo or active control in patients undergoing craniotomy under general anesthesia met the criteria for inclusion in this comprehensive narrative review. The pathophysiology and mechanisms of PONV after craniotomy could be multifactorial in etiology. Therefore, based on current evidence, PONV management after craniotomy should focus on perioperative patient assessment, surgical, and anesthesia-related risk factors and the selection of systemic pharmacological considerations to reduce its incidence and complications. A multimodal regimen of medication targeting different chemoreceptors in the vomiting center is recommended. Ondansetron and dexamethasone, or their combination, are the most frequently used and effective agents. Further randomized clinical trials comparing different regimens that significantly reduce the incidence of PONV in craniotomy would provide relevant evidence-based data for PONV management in this patient population.

Acupuncture therapy strategy options in postoperative management after laparoscopic cholecystectomy: A protocol for systematic review and Bayesian meta-analysis

BACKGROUND

Laparoscopic cholecystectomy (LC) is a common surgery accompanied by some unpleasant adverse effects. Clinical trials indicated that acupuncture therapy may help reduce complications in LC. However, no systematic reviews have been conducted on the topic. Therefore, we will evaluate the current evidence and provide a rank for the efficacy of acupuncture therapy in LC by performing Bayesian network meta-analysis.

METHODS

A total of 9 databases will be searched from inception to 10 December 2020. Randomized control trails met the criterion will be included. Quality evaluation of included studies will be performed using Cochrane risk-of-bias tool. STATA 14.0, Addis 1.16.8, R 3.6.3, and OpenBUGS 3.2.3 will be used to conduct pairwise meta-analysis and network meta-analysis. The evidence will be assessed by the Grades of Recommendations Assessment Development and Evaluation.

RESULTS

This review will be based on clinical evidence to choose the best choice of acupuncture treatment for LC. And the results will be submitted to a peer-reviewed journal for publication.

CONCLUSION

Through this systematic review, we will summarize the best available evidence of acupuncture therapy in LC and help to improve the clinical decision-making ability in LC domain.

Inhaled anesthesia in neurosurgery: Still a role?

In patients undergoing craniotomy, general anesthesia should be addressed to warrant good hypnosis, immobility, and analgesia, to ensure systemic and cerebral physiological status and provide the best possible surgical field. Regarding craniotomies, it is unclear if there are substantial differences in providing general anesthesia using total intravenous anesthesia (TIVA) or balanced anesthesia (BA) accomplished using the third generation halogenates. New evidence highlighted that the last generation of halogenated agents has possible advantages compared with intravenous drugs: rapid induction, minimal absorption and metabolization, reproducible pharmacokinetic, faster recovery, cardioprotective effect, and opioid spare analgesia. This review aims to report evidence related to the use of the latest halogenated agents in patients undergoing craniotomy and to present available clinical evidence on their effects: cerebral and systemic hemodynamic, neurophysiological monitoring, and timing and quality of recovery after anesthesia.

A Malaysian retrospective study of acupuncture-assisted anesthesia in breast lump excision

INTRODUCTION

The objective of this retrospective study was to evaluate the effectiveness and safety of acupuncture-assisted anesthesia (AAA) in breast lump excision.

METHODS

The medical records of all patients who underwent breast lump excision under AAA in combination with electrical stimulation at traditional acupuncture points in 2016 were examined. All of them (n = 17) received electrostimulation (2-4 Hz) using single needles inserted at bilateral LI4 and PC6. They also underwent insertion of four acupuncture needles at the lump site, which were electrically stimulated at 30 Hz frequency.

RESULTS

All surgical procedures were successful with minimal use of analgesics and local anesthetic. The median pain score reported was 1/10 (interquartile range (IQR) = 2/10) at the first hour, and slightly increased to 2/10 (IQR = 2/10) between 24 and 48 h of the surgery. No major postoperative adverse events were documented, except for drowsiness in one case.

CONCLUSION

AAA was found to be generally safe and effective for anaesthesia and analgesia in breast lump excision. However, a large-scale randomized controlled study is required to verify the findings.

Integrating complementary medicine in the perioperative period: a simple, opioid-sparing addition to your multimodal analgesia strategy?

The current US opioid health-related crisis underscores the importance for perioperative physicians to optimize various approaches to pain management. Multimodal techniques and enhanced recovery after surgery (ERAS) protocols are frequently cited as the most effective strategies for improving the experience of pain and reducing opioid exposure. Complementary medicine (CM) techniques, while frequently shown to be effective at reducing opioid and other pharmacologic agent use, are rarely discussed as part of these multimodal strategies. In general, CM therapies are low-cost with minimal associated risk, making them an ideal choice for incorporation into ERAS and other opioid-sparing protocols. In this Daring Discourse, we discuss the benefits and challenges of incorporating CM therapy into anesthetic practice. We hope that anesthesiologists can become more familiar with the current evidence regarding perioperative CM therapy, and begin incorporating these therapies as part of their comprehensive multimodal approach to perioperative pain management.

Acupuncture attenuates postoperative inflammation in patients after craniotomy: A prospective, open-label, controlled trial

BACKGROUND

It is important to manage inflammation after craniotomy. It may be prudent to reduce the excessive usage of antibiotics and to add supplementary treatments like acupuncture, which would be effective and safe. However, there are only a few studies available to date on the effects of acupuncture on anti-inflammatory response after craniotomy. The aim of this study was to explore the anti-inflammatory effects of acupuncture in patients after a craniotomy.

METHODS

This study was a single-center, prospective, open-label, controlled trial. Forty-four subjects who underwent craniotomy for an unruptured aneurysm, facial spasm, or brain tumor were allocated to either an acupuncture group or a control group. Both groups received postoperative routine care in the Department of Neurosurgery. The subjects in the acupuncture group also received a total of 6 acupuncture treatments sessions within 8 days after craniotomy. Acupuncture treatments included acupuncture, electroacupuncture, and intradermal acupuncture. The serum interleukin (IL)-1β and IL-6, tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and erythrocyte sedimentation rate levels were assessed four times within 7 days after surgery. The presence of fever, use of additional antibiotics, presence of infection including pneumonia or urinary tract infection, and safety were also reviewed.

RESULTS

The IL-1β levels of subjects who underwent aneurysmal clipping were significantly lower in the acupuncture group (P = .02). TNF-α levels of subjects who underwent aneurysmal clipping at the seventh postoperative day were also significantly lower in the acupuncture group (P = .03). Six cases of fever of unknown origin were observed in the control group, while none were seen in the acupuncture group, revealing that the incidence of fever was significantly lower in the acupuncture group (P = .02). No adverse events occurred during the trial.

CONCLUSION

Acupuncture showed a possibility of alleviating inflammation by attenuating the levels of proinflammatory cytokines and significantly reduced the incidence of fever of unknown origin in patients after craniotomy. Acupuncture would be suitable as an adjunctive therapy to alleviate inflammation after craniotomy.

Application of Acupuncture to Attenuate Immune Responses and Oxidative Stress in Postoperative Cognitive Dysfunction: What Do We Know So Far?

Postoperative cognitive dysfunction (POCD) is a common sequela following surgery and hospitalization. The prevention and management of POCD are important during clinical practice. POCD more commonly affects elderly patients who have undergone major surgery and can result in major decline in quality of life for both patients and their families. Acupuncture has been suggested as an effective intervention for many neurological disorders. In recent years, there are increasing interest in the use of acupuncture to prevent and treat POCD. In this review, we summarized the clinical and preclinical evidence of acupuncture on POCD using a narrative approach and discussed the potential mechanisms involved. The experimental details and findings of studies were summarized in tables and analyzed. Most of the clinical studies suggested that acupuncture before surgery could reduce the incidence of POCD and reduce the levels of systematic inflammatory markers. However, their reliability is limited by methodological flaws. Animal studies showed that acupuncture reduced cognitive impairment and the associated pathology after various types of surgery. It is possible that acupuncture modulates inflammation, oxidative stress, synaptic changes, and other cellular events to mitigate POCD. In conclusion, acupuncture is a potential intervention for POCD. More clinical studies with good research design are required to confirm its effectiveness. At the same time, findings from animal studies will help reveal the protective mechanisms, in which systematic inflammation is likely to play a major role.

Effects of Transcutaneous Electrical Acupoint Stimulation on the Postoperative Sleep Quality and Pain of Patients After Video-Assisted Thoracoscopic Surgery: A Prospective, Randomized Controlled Trial

OBJECTIVE

Postoperative sleep disturbances have serious adverse effects on postoperative outcomes. Our paper aimed to observe the effect of using transcutaneous electrical acupoint stimulation (TEAS) on sleep quality and complications after surgery in patients undergoing selective video-assisted thoracoscopic surgery.

PATIENTS AND METHODS

Eighty-five patients were divided into the TEAS group or the control group randomly. Thirty minutes of TEAS treatment was performed on TEAS group at the following time points: the first night before surgery, at the end of surgery, and before sleeping on the second and third nights after surgery. The Portable Sleep Monitor (PSM) was performed to determine the sleep quality of the two nights before the operation (Sleep preop 2 and Sleep preop 1) and the first and third night after surgery (Sleep POD 1 and Sleep POD 3). The visual analog scale (VAS) was performed to evaluate pain scores after surgery and the Athens Insomnia Scale (AIS) was used for evaluating subjective sleep quality.

RESULTS

Participants in the TEAS group had a lower AIS score and higher sleep efficiency at each time point except Sleep preop 2. Participants in the TEAS group showed significantly higher proportion of each sleep stage during Sleep-preop 1, Sleep POD 1, and Sleep POD 3. Patients in the TEAS group had significantly lower VAS scores at 2, 4, and 6 h during the first 24 h after surgery. The incidence of nausea and vomiting and dizziness in the control group was statistically higher than in the TEAS group.

CONCLUSION

Patients usually have sleep disturbances after video-assisted thoracoscopic surgery, such as decreased distribution of each sleep stage, lower sleep efficiency, and higher AIS score. Undergoing TEAS treatment perioperatively can improve sleep quality, and effectively promote the postoperative analgesic effect and alleviate postoperative complications.

Intradermal thumbtack needle buried Neiguan (P6) point for prevention of postoperative nausea and vomiting in patients undergoing craniotomy: study protocol for a randomised controlled trial

INTRODUCTION

Postoperative nausea and vomiting (PONV) is among the most common adverse reactions following anaesthesia and surgery. Recent clinical studies have reported that the average incidence is about 30%, while in patients specifically undergoing neurosurgery, the incidence can be as great as 73%. Studies also suggest that its occurrence increases the risk of intracranial haematoma and haemorrhage. The objective of this study is to evaluate the effectiveness of intradermal thumbtack needle buried Neiguan (pericardium 6 (P6)) point therapy in the prevention of PONV in patients undergoing craniotomy under general anaesthesia.

METHODS AND ANALYSIS

This is a single-centre, three-arm, randomised controlled trial. 180 participants are randomly assigned to either an acupuncture, intradermal thumbtack needle or control group in a 1:1:1 ratio. The P6 of the acupuncture group is punctured at both sides perpendicularly to a depth of 20 mm. Needles are retained for 30 min and stimulated every 10 min to maintain the de qi. The therapy includes two treatments; the acupuncture is administered immediately after and 24 hours after surgery. For the intradermal thumbtack needle group, the intradermal thumbtack needle is quickly inserted into the skin and embedded at P6 acupoints bilaterally. Patients and their families are asked to press the needlepoint with the onset of nausea, vomiting, bloating, pain and other reported discomforts. The needle is replaced after 24 hours. The therapy is administered immediately after and 24 hours after surgery. For the control group, no intervention is carried out. The incidence of PONV within 48 hours after craniotomy across the three groups is observed. Other observations include: (1) assessment of nausea score (severity of nausea) and pain score (visual analogue scale) 0-2, 2-6, 6-24 and 24-48 hours after craniotomy under general anaesthesia; (2) assessment of total rescue antiemetic dosage 0-48 hours after craniotomy under general anaesthesia; (3) length of hospital stay and (4) patient satisfaction score with PONV management. We will perform all statistical analysis following the intention-to-treat principle.

ETHICS AND DISSEMINATION

Ethics approval has been granted by the Bioethics Subcommittee of the West China Hospital, Sichuan University: the approval number is 2018 (number 231). Results will be expected to be published in peer-reviewed journals.

Narrative review of acute post-craniotomy pain. Concept and strategies for prevention and treatment of pain

The aim of this narrative review is to confirm that acute pain after craniotomy is frequent and presents with moderate to severe intensity. We also highlight the importance of not only treating post-craniotomy pain, but also of preventing it in order to reduce the incidence of chronic pain. Physicians should be aware that conventional postoperative analgesics (non-steroidal anti-inflammatory, paracetamol, cyclooxygenase inhibitors 2, opioids) are not the only options available. Performing a scalp block prior to surgical incision or after surgery, the use of intraoperative dexmedetomidine, and the perioperative administration of pregabalin are just some alternatives that are gaining ground. The management of post-craniotomy pain should be based on perioperative multimodal analgesia in the framework of an "enhaced recovery after surgery" (ERAS) approach.

Naturopathic Treatment and Complementary Medicine in Surgical Practice

BACKGROUND

Many patients in Germany use naturopathic treatments and complementary medicine. Surveys have shown that many also use them as a concomitant treatment to surgery.

METHODS

Multiple databases were systematically searched for systematic reviews, controlled trials, and experimental studies concerning the use of naturopathic treatments and complementary medicine in the management of typical post-operative problems (PROSPERO CRD42018095330).

RESULTS

Of the 387 publications identified by the search, 76 fulfilled the inclusion criteria. In patients with abnormal gastrointestinal activity, acupuncture can improve motility, ease the passing of flatus, and lead to earlier defecation. Acupuncture and acupressure can reduce postoperative nausea and vomiting, as well as pain. More-over,aromatherapy and music therapy seem to reduce pain, stress and anxiety and to improve sleep. Further studies are needed to determine whether phytotherapeutic treatments are effective for the improvement of gastrointestinal function or the reduction of stress. It also remains unclear whether surgical patients can benefit from the methods of mind body medicine.

CONCLUSION

Certain naturopathic treatments and complementary medical methods may be useful in postoperative care and deserve more intensive study. In the publications consulted for this review, no serious side effects were reported.

Acupuncture could relieve anxiety and stress during the preoperative stage. It reduces the usage of narcotics and stress response, and maintains the respiratory stability and homeostasis during surgery. It also exerts a protective effect on vital organs, and during the postoperative stages, enhances the recovery while effectively alleviating the postoperative pain. This phenomenon prevents common postoperative discomforts such as nausea and vomiting. In addition, it might improve the patients’ long-term prognosis.

Conclusions:

The novel concept “perioperative acupuncture medicine” is to focus on the optimal treatment in the perioperative period of surgical patients. The review reveals the important role of acupuncture in enhancing rapid recovery of patients during the perioperative period.

Acupuncture in Inflammatory Bowel Disease

Scientific research into the effects and mechanisms of acupuncture for gastrointestinal diseases including inflammatory bowel disease has been rapidly growing in the past several decades. In this review, we discuss the history, theory, and methodology of acupuncture and review potentially beneficial mechanisms of action of acupuncture for managing inflammatory bowel disease. Acupuncture has been shown to decrease disease activity and inflammation via increase of vagal activity in inflammatory bowel disease. Acupuncture has demonstrated beneficial roles in the regulation of gut dysbiosis, intestinal barrier function, visceral hypersensitivity, gut motor dysfunction, depression/anxiety, and pain, all of which are factors that can significantly impact quality of life in patients with inflammatory bowel disease. A number of clinical trials have been performed to investigate the therapeutic effects of acupuncture in ulcerative colitis and Crohn's disease. Although the data from these trials are promising, more studies are needed given the heterogeneous and multifactorial aspects of inflammatory bowel disease. There is also an important need to standardize acupuncture methodology, study designs, and outcome measurements.

Effects of Transcutaneous Electrical Acupoint Stimulation on the Stress Response During Extubation After General Anesthesia in Elderly Patients Undergoing Elective Supratentorial Craniotomy: A Prospective Randomized Controlled Trial

BACKGROUND

Elderly patients have an increased risk of a stress response during extubation after general anesthesia. In this study, we aimed to investigate whether transcutaneous electrical acupoint stimulation (TEAS) might decrease the stress response and improve the quality of recovery in elderly patients after elective supratentorial craniotomy.

MATERIALS AND METHODS

In this prospective randomized controlled study, patients were randomly assigned to either a TEAS group (n=37) or a control group (n=38). The primary outcomes were the hemodynamic parameters and plasma concentrations of epinephrine, norepinephrine, and cortisol. The secondary outcome included the consumption of remifentanil and propofol, time to extubation and reorientation, extubation quality score, postoperative quality of recovery, and postoperative complications.

RESULTS

Compared with the control group, hemodynamic parameters and plasma concentrations of epinephrine, norepinephrine, and cortisol during extubation were decreased in the TEAS group. TEAS reduced the consumption of remifentanil (P<0.01), as well as incidence of postoperative complications. The extubation quality score was lower (P<0.01) and the quality of recovery score was higher (P<0.01) in the TEAS group than in the control group. However, the time to extubation and reorientation, and the consumption of propofol were not significantly different between the 2 groups.

CONCLUSIONS

TEAS may decrease the stress response during extubation, improve quality of postoperative recovery, and decrease incidence of postoperative complications in elderly patients undergoing elective supratentorial craniotomy.

[Open heart surgery under acupuncture ? Decrypting a program broadcast on France 2]

OBJECTIVES

To analyze a clip from the program ? Acupuncture, osteopathy, hypnosis: do complementary medicines have superpowers ? about acupuncture as an anesthetic for surgical procedures in China. To propose a rational explanation for the phenomena observed. To describe the processes leading a public service broadcasting channel to offer this type of content at prime time and the potential consequences in terms of public health.

METHOD

Analysis using critical thinking attitudes and skills, along with a bibliographical search of Medline, Google Scholar and Cochrane Library databases.

RESULTS

The information delivered in the television clip is ambiguous. It does not allow the viewer to form an informed opinion on the relevance of acupuncture as an anesthetic for surgical procedures. It is reasonable to assume that the clip shows surgery performed with undisclosed epidural anesthesia coupled with mild intravenous anesthesia, sometimes performed in other countries. What needs to be highlighted here is the overestimation of acupuncture added to the protocol. The media tend to exaggerate the risks and expected effects of the treatments they report on, which can lead patients to turn to unproven therapies.

CONCLUSION

Broadcasting such a clip at prime time underlines the urgent need for the public and all health professionals to be trained in sorting and critically analyzing health information.

Integrative care of the patient with head and neck cancer

Objective

To review the literature on integrative care of the patient with head and neck cancer.

Methods

A review of the English language literature for articles relating to integrative care of patients with head and neck cancer, focusing on treatment of sequelae of surgery and chemoradiation.

Results

Many studies show a significant utilization of nontraditional (complementary/integrative) treatments by patients in dealing with head and neck cancer. Treatment of head and neck cancer entails potentially debilitating consequences of surgery and/or chemoradiation on cosmesis, speech, swallowing, breathing, and quality of life. While complementary/integrative treatments for head and neck cancer are not established as effective therapies, their use for relieving sequelae of treatment, improving quality of life, and providing potential chemoprevention is well documented.

Conclusion

Given the landscape of increasing use of nontraditional methodologies by patients with head and neck cancer and the complexity of care, the head and neck cancer surgeon should be aware of the uses and abuses of complementary/integrative medicine by patients as they navigate their care.

Effect of acupuncture on post-hemorrhoidectomy pain: a randomized controlled trial

Objectives

To observe the clinical efficacy and safety of electroacupuncture (EA) in relieving pain after hemorrhoidectomy treatment for mixed hemorrhoids.

Design

This was a randomized controlled trial.

Methods

We conducted a single-center, single-blind, and randomized controlled clinical trial. Seventy-two patients with mixed hemorrhoids who had undergone hemorrhoidectomy were randomly assigned to the following 2 groups: the EA treatment group (EA) received surround needling with EA (n=36), and the control group received sham acupuncture (SA) treatment (n=36). The treatment was conducted within 15 min after the completion of the surgery and lasted for 30 min. The pain intensity was recorded by using the visual analog scale as the primary outcome. Secondary outcomes were verbal rating scale and Wong-Baker Faces Pain Rating. These measurements were evaluated at 11 time points: once every hour in the first 8 h after the treatment, 24 and 48 h after the treatment, and at the first defecation. Besides, quality of life was measured by Symptom Checklist-90 Scale at 24 and 48 h follow-ups.

Results

The EA group had significantly lower visual analog scale scores at the 3 time points of 6, 24 h, and during the defecation (p<0.05). Verbal rating scale showed a significantly lower score in the treatment group compared to the SA group at 4 h after the treatment as well as during defecation (p<0.05). The Wong-Baker Faces Pain Rating scores of EA group were significantly lower at 5, 7, and 8 h after treatment and during defecation (p<0.05) compared with those of SA group.

Conclusion

Acupuncture is effective in alleviating postoperative pain in patients who have undergone hemorrhoidectomy.

Acupuncture's Role in Solving the Opioid Epidemic: Evidence, Cost-Effectiveness, and Care Availability for Acupuncture as a Primary, Non-Pharmacologic Method for Pain Relief and Management-White Paper 2017

The United States (U.S.) is facing a national opioid epidemic, and medical systems are in need of non-pharmacologic strategies that can be employed to decrease the public's opioid dependence. Acupuncture has emerged as a powerful, evidence-based, safe, cost-effective, and available treatment modality suitable to meeting this need. Acupuncture has been shown to be effective for the management of numerous types of pain conditions, and mechanisms of action for acupuncture have been described and are understandable from biomedical, physiologic perspectives. Further, acupuncture's cost-effectiveness can dramatically decrease health care expenditures, both from the standpoint of treating acute pain and through avoiding addiction to opioids that requires costly care, destroys quality of life, and can lead to fatal overdose. Numerous federal regulatory agencies have advised or mandated that healthcare systems and providers offer non-pharmacologic treatment options for pain. Acupuncture stands out as the most evidence-based, immediately available choice to fulfil these calls. Acupuncture can safely, easily, and cost-effectively be incorporated into hospital settings as diverse as the emergency department, labor and delivery suites, and neonatal intensive care units to treat a variety of commonly seen pain conditions. Acupuncture is already being successfully and meaningfully utilized by the Veterans Administration and various branches of the U.S. Military, in some studies demonstrably decreasing the volume of opioids prescribed when included in care.

Prophylaxis of postoperative complications after craniotomy

PURPOSE OF REVIEW

This review reports an update of the evidence on practices applied for the prevention and management of the most common complications after craniotomy surgery.

RECENT FINDINGS

Latest guidelines support the combined thromboprophylaxis with the use of both mechanical and chemical modalities, preferably applied within 24 h after craniotomy. Nevertheless, a heightened risk of minor hemorrhagic events remains an issue of concern. Postoperative nausea and vomiting (PONV) and pain constitute the complications most commonly encountered during the first 24 h postcraniotomy. Recently, neurokinin type-1 receptor antagonists have been tested as adjuncts for PONV prophylaxis with encouraging results, whereas dexmedetomidine and gabapentinoids emerge as promising alternatives for postcraniotomy pain management. The available data for seizure prophylaxis following craniotomy lacks scientific quality; thus, this remains still a debatable issue. Significantly, a growing body of evidence supports the superiority of levetiracetam over the older antiepileptic drugs (AEDs), in terms of efficacy and safety.

SUMMARY

Optimum management of postoperative complications is incorporated as an integral part of the augmented quality of care in patients undergoing craniotomy surgery, aiming to improve outcomes. This review may serve as a benchmark for neuroanesthetists for heightened clinical awareness and prompt institution of well-documented practices.

Enhanced recovery after surgery: Neuroanaesthetic perspective

Enhanced recovery after surgery (ERAS) is a systematic multimodal perioperative care aimed at reducing the immense surgical stress of the patient and thereby facilitating early recovery. This is basically a multidiscipline, multimodal integrated approach in patient care and it integrates the basic knowledge in a more streamlined fashion, which ultimately improves the outcome of surgery. This article reviews the various aspects of ERAS, and its implementation in neurosurgical practice as some concepts of ERAS may not be applicable in the setting of neurosurgery.

Meta-Analysis of Electroacupuncture in Cardiac Anesthesia and Intensive Care

BACKGROUND

Acupuncture treatment has been employed in China for over 2500 years and it is used worldwide as analgesia in acute and chronic pain. Acupuncture is also used in general anesthesia (GA). The aim of this systematic review and meta-analysis was to assess the efficacy of electroacupuncture (EA) in addition to GA in patients undergoing cardiac surgery.

METHODS

We searched 3 databases (Pubmed, Cochrane Library, and Web of Science-from 1965 until January 31, 2017) for randomized controlled trials (RCTs) including patients undergoing cardiac surgery and receiving GA alone or GA + EA. As primary outcomes, we investigated the association between GA + EA approach and the dosage of intraoperative anesthetic drugs administered, the duration of mechanical ventilation (MV), the postoperative dose of vasoactive drugs, the length of intensive care unit (ICU) and hospital stay, and the levels of troponin I and cytokines.

RESULTS

The initial search yielded 477 citations, but only 7 prospective RCTs enrolling a total of 321 patients were included. The use of GA + EA reduced the dosage of intraoperative anesthetic drugs (P < .05), leading to shorter MV time (P < .01) and ICU stay (P < .05) as well as reduced postoperative dose of vasoactive drugs (P < .001). In addition, significantly lower levels of troponin I (P < .01) and tumor necrosis factor α (P < .01) were observed.

CONCLUSION

The complementary use of EA for open-heart surgery reduces the duration of MV and ICU stay, blunts the inflammatory response, and might have protective effects on the heart. Our findings stimulate future RCT to provide definitive recommendations.

Cost-effectiveness of acupuncture in an employee population: A retrospective analysis

OBJECTIVES

To determine whether acupuncture is a cost-effective adjunct to usual care for Mayo Clinic employees and their dependents experiencing pain symptoms.

DESIGN

Retrospective review of the medical and billing records of 466 employee-patients and their dependents who had received acupuncture as part of their care and 466 propensity score-matched control patients.

INTERVENTIONS

Usual care in combination with acupuncture compared with usual care alone.

MAIN OUTCOME MEASURES

The primary outcome measure was the total costs of care for all medical care and pharmacy services incurred from 1year before the index visit to 14 months after the index date. Secondary outcomes included the number of hospital visits, total inpatient days, emergency department visits, primary care or general medicine office visits, specialty office visits, and physical therapy services. Pain scores (patient-rated scores from 0 to 10) were extracted from the medical record, if available.

RESULTS

Costs of care were similar between the 2 groups. No cost savings were noted for the acupuncture group.

CONCLUSIONS

Several limitations to the study may have precluded a finding of cost-effectiveness. Future studies should include prospective evaluation of costs and other outcomes in a comparison between acupuncture and usual care in a randomized control trial.

Cardioprotection of Electroacupuncture for Enhanced Recovery after Surgery on Patients Undergoing Heart Valve Replacement with Cardiopulmonary Bypass: A Randomized Control Clinical Trial

We attempted to investigate cardioprotection of electroacupuncture (EA) for enhanced recovery after surgery on patients undergoing heart valve replacement with cardiopulmonary bypass. Forty-four patients with acquired heart valve replacement were randomly allocated to the EA group or the control group. Patients in the EA group received EA stimulus at bilateral Neiguan (PC6), Ximen (PC4), Shenting (GV24), and Baihui (GV20) acupoints twenty minutes before anesthesia induction to the end of surgery. The primary end point was cardioprotection effect of electroacupuncture postoperatively and the secondary endpoints were quality of recovery and cognitive functioning postoperatively. The present study demonstrated that electroacupuncture reduced the occurrence of complications and played a role of cardioprotective effect on patients after heart valve replacement surgery with cardiopulmonary bypass, and it benefits patients more comfortable and contributes to recovery after surgery. This trial is registered with ChiCTR-IOC-16009123.
