The role of acupuncture and transcutaneous-electrical nerve stimulation for postoperative pain control

Integrating complementary and alternative medicine in surgical care: A narrative review

Complementary and integrative medicine (CIM) is increasingly being integrated into preoperative, intraoperative, and postoperative phases to enhance patient outcomes, manage symptoms, and improve overall well-being. CIM encompasses a broad range of therapies and practices that are not typically part of conventional medical care, such as herbal and non-herbal medicine, yoga, acupuncture, meditation, chiropractic care, and dietary supplements. This review explores the existing evidence on the application, benefits, and challenges of CIM therapies and practices in surgical settings, highlighting the importance of integrating these therapies and approaches with conventional medical practices to enhance patient outcomes.

Manual therapies in cystic fibrosis care: a scoping review

OBJECTIVES

To review the use of manual therapies (MT) for pain, respiratory muscle strength and pulmonary function in cystic fibrosis (CF) care.

METHODS

A search with a systematic approach was conducted by two independent reviewers, using the databases Medline, PubMed, Scopus and Cinahl from their respective inception dates to March 2021.

RESULTS

A total of 199 publications were initially screened by title and abstract, after which 190 were excluded. Following a full-text review of the remaining articles, six studies with a total of 234 participants were included. Decreased pain levels following MT were observed in two studies and, in three studies, patient reports on improvement in ease of breathing and peak airflow were presented. No significant effects on spirometry measures were observed and none of the included studies investigated respiratory muscle strength.

CONCLUSION

Current research on MT in CF care indicates positive trends based on subjective measures. However, research in this context is sparse and disparate in terms of both interventions and methodology. Further investigations including MT as part of multimodal interventions are therefore suggested before any specific recommendations for clinical implementation of MT in CF can be provided.

Opioid sparing strategies for perioperative pain management other than regional anaesthesia: A narrative review

Opioids play a crucial role in pain management in spite of causing increased hospital morbidity and related costs. It may also cause significant risks such as postoperative nausea and vomiting (PONV), sedation, sleep disturbances, urinary retention and respiratory depression (commonly referred to as opioid related adverse effects) in postoperative patients. In order to evade these opioid related side effects and also improve pain management, multimodal analgesia i.e., combination of different analgesics, was introduced more than a decade ago. Both pharmacological and non-pharmacological techniques are available as opioid sparing analgesia. Research from around the world have proved pharmacological techniques ranging from acetaminophen, NSAIDs (non-steroidal anti-inflammatory drugs), N-methyl-D-aspartate receptor antagonists (NDMA), alpha-2 agonists, anticonvulsants such as gamma aminobutyric acid analogues, beta-blockers, capsaicin, lignocaine infusion to glucocorticoids to be effective. On the other hand, non-pharmacological methods include techniques such as cognitive behavioral therapy, transcutaneous electrical nerve stimulation (TENS), electroanalgesia, acupuncture and hypnosis. However, research regarding the effect of these non-pharmacological techniques on pain management is still needed.

Effect of intracutaneous pyonex on analgesia and sedation in critically ill patients with mechanical ventilation

The purpose of this study was to evaluate the effect of intracutaneous pyonex on analgesia and sedation in critically ill patients who underwent mechanical ventilation. A total of 88 critically ill patients were divided into a control group and an intervention group. Critical Care Pain Observation Tool (CPOT) and Richmond Agitation and Sedation Scale (RASS) were used to evaluate pain and agitation. The dosage and treatment period of sedative and analgesic drugs in the intervention group were notably lower than the control group (p < 0.05). Analgesia compliance time in the intervention group was superior to control group (p < 0.05). The shallow sedation compliance rate in the intervention group was significantly higher than the control group (p < 0.01). There was significant difference in blood gas analysis before and after treatment between the two groups (p < 0.05). After 2 h of sedation and analgesia, heart rate in the intervention group was lower than control group, but respiratory rate was higher than the control group (p < 0.05). The traditional analgesia and sedation combined with intracutaneous pyonex reduced the total amount and treatment period of sedative and analgesic drugs in critically ill patients throughout the treatment process, and it also decreased the adverse reactions such as blood pressure drops and respiratory depression.

The Role of Acupuncture in Postoperative Pain Management of Patients Undergoing Knee Arthroplasty Surgery: A Systematic Review and Meta-Analysis

»

Acupuncture after total knee arthroplasty (TKA) may decrease the incidence of postoperative nausea and vomiting (PONV).

»

Acupuncture did not decrease visual analog scale (VAS) scores in the 0 to 48-hour interval but did decrease VAS scores at >48 hours after TKA.

»

The heterogeneity of the studies prevented meta-analysis of opioid use with acupuncture after TKA; a systematic review demonstrated mixed results.

»

Additional studies are needed to investigate opioid reduction with acupuncture after TKA.

[Is supplemental ear acupuncture for surgical tooth removal with local anesthesia effective? : A pilot study]

BACKGROUND

The application of ear acupuncture can contribute to a reduction of acute pain. Data on the application of ear acupuncture following oral surgery in odontology is insufficient.

OBJECTIVE

This study investigated the effectiveness of ear acupuncture as an auxiliary analgesic treatment in addition to local anesthesia for operative tooth removal.

METHODS

In this prospective open non-randomized pilot study (in accordance with the CONSORT publication) 2 cohorts of 50 patients each with the indications for an operative tooth removal either with or without the application of ear acupuncture in addition to local anesthesia with articain were observed. Patients were allocated to the groups according to their preference. Pain intensity while resting and while chewing was recorded as the primary parameter for a period of 10 days. The secondary parameters were the subjective experience of anxiety and symptoms, such as headaches, dizziness and nausea.

RESULTS

The two groups did not differ significantly with respect to demographic variables or the use of local anesthetics. At the various measurement intervals, pain intensity while resting or chewing differed significantly between the two groups (ANOVA, p = 0.004, p = 0.007, respectively). Furthermore, the experience of anxiety (ANOVA, p = 0.0001), the number of patients taking analgesics (χ²-test, p = 0.017) and the total postoperative consumption of analgesics (t-test, 0.001) revealed significant differences. In both groups the numerical rating scales (NRS) for postoperative headaches, dizziness and nausea were low.

DISCUSSION AND CONCLUSION

Despite a potential bias and methodological limitations of the study design, the results of this investigation suggest that ear acupuncture influences the experience of pain and anxiety in the postoperative period after tooth removal. As a treatment method with low adverse effects ear acupuncture can contribute to postoperative pain control, especially in patients with preoperative anxiety.

Acupuncture for pain control after Caesarean section: a prospective observational pilot study

OBJECTIVE

Options for pharmacological analgesia in patients who have undergone Caesarean section (CS) are often restricted. Acupuncture is a promising tool for treating postoperative pain. We aimed to study the feasibility and acceptability of acupuncture as an additional method of analgesia in CS patients in a prospective observational pilot investigation.

METHODS

Twenty-two patients scheduled for elective CS under spinal anaesthesia were enrolled according to set inclusion criteria. Each patient received auricular and body acupuncture with 20 indwelling fixed needles according to previously validated protocols of acupuncture for postoperative analgesia. Pain intensity on an 11-point verbal rating scale (VRS-11, where 0=no pain and 10=maximal pain), analgesia-related side effects, time to mobilisation and Foley catheter removal after CS, and patients' compliance and satisfaction with treatment of pain on a 5-point VRS (VRS-5, where 1=excellent; 5=bad) were recorded.

RESULTS

Twenty patients were included in the final analysis. One patient was disturbed by paraesthesia at the site of needling. All other patients tolerated acupuncture well. Pain intensity on movement on the first postoperative day was 4.3±2.4 (mean±SD; VRS-11) and decreased to 2.2±1.2 on the day of discharge. Patient satisfaction was 1.9±0.8 (mean±SD; VRS-5) and compliance (rated by their nurses) was 1.5±0.5 (mean±SD; VRS-5).

CONCLUSIONS

Acupuncture for additional analgesia after CS was well accepted. The primary outcome measurement was feasible and allowed the sample size to be calculated for a future randomised controlled trial.

Electroacupuncture for bladder function recovery in patients undergoing spinal anesthesia

Purpose. To determine the efficacy of electroacupuncture on recovering postanesthetic bladder function. Materials and Methods. Sixty-one patients undergoing spinal anaesthesia were recruited and allocated into electroacupuncture or control group randomly. Patients in electroacupuncture group received electroacupuncture therapy whereas ones in control group were not given any intervention. Primary endpoint was incidence of bladder overdistension and postoperative urinary retention. Secondary endpoints included time to spontaneous micturition, voided volume, and adverse events. Results. All patients (31 in electroacupuncture group and 30 in control group) completed the evaluation. During postoperative follow-up, patients in electroacupuncture group presented a significant lower proportion of bladder overdistension than counterparts in control group (16.1% versus 53.3%, P < 0.01). However, no significant difference was found in incidence of postoperative urinary retention between the two groups (0% versus 6.7%, P > 0.05). Furthermore, a shorter time to spontaneous micturition was found in electroacupuncture group compared to control group (228 min versus 313 min, P < 0.001), whereas urine volume and adverse events had no significant difference between the two groups. Conclusions. Electroacupuncture reduced the proportion of bladder overdistension and shortened the time to spontaneous micturition in patients undergoing spinal anesthesia. Electroacupuncture may be a therapeutic strategy for postanesthetic bladder dysfunction.

Comparison of electroacupuncture and morphine-mediated analgesic patterns in a plantar incision-induced pain model

Electroacupuncture (EA) is a complementary therapy to improve morphine analgesia for postoperative pain, but underlying mechanism is not well-known. Herein, we investigated EA-induced analgesic effect in a plantar incision (PI) model in male Sprague-Dawley rats. PI was performed at the left hind paw. EA of 4 Hz and high intensity or sham needling was conducted at right ST36 prior to PI and repeated for another 2 days. Behavioral responses to mechanical and thermal stimuli, spinal phospho-ERK, and Fos expression were all analyzed. In additional groups, naloxone and morphine were administered to elucidate involvement of opioid receptors and for comparison with EA. EA pretreatment significantly reduced post-PI tactile allodynia for over 1 day; repeated treatments maintained analgesic effect. Intraperitoneal naloxone could reverse EA analgesia. Low-dose subcutaneous morphine (1 mg/kg) had stronger inhibitory effect on PI-induced allodynia than EA for 1 h. However, analgesic tolerance appeared after repeated morphine injections. Both EA and morphine could equally inhibit PI-induced p-ERK and Fos inductions. We conclude that though EA and morphine attenuate postincision pain through opioid receptor activations, daily EA treatments result in analgesic accumulation whereas daily morphine injections develop analgesic tolerance. Discrepant pathways and mechanisms underlying two analgesic means may account for the results.

Acupuncture with manual and electrical stimulation for labour pain: a longitudinal randomised controlled trial

Background

Acupuncture is commonly used to reduce pain during labour despite contradictory results. The aim of this study is to evaluate the effectiveness of acupuncture with manual stimulation and acupuncture with combined manual and electrical stimulation (electro-acupuncture) compared with standard care in reducing labour pain. Our hypothesis was that both acupuncture stimulation techniques were more effective than standard care, and that electro-acupuncture was most effective.

Methods

A longitudinal randomised controlled trial. The recruitment of participants took place at the admission to the labour ward between November 2008 and October 2011 at two Swedish hospitals . 303 nulliparous women with normal pregnancies were randomised to: 40 minutes of manual acupuncture (MA), electro-acupuncture (EA), or standard care without acupuncture (SC). Primary outcome: labour pain, assessed by Visual Analogue Scale (VAS). Secondary outcomes: relaxation, use of obstetric pain relief during labour and post-partum assessments of labour pain. The sample size calculation was based on the primary outcome and a difference of 15 mm on VAS was regarded as clinically relevant, this gave 101 in each group, including a total of 303 women.

Results

Mean estimated pain scores on VAS (SC: 69.0, MA: 66.4 and EA: 68.5), adjusted for: treatment, age, education, and time from baseline, with no interactions did not differ between the groups (SC vs MA: mean difference 2.6, 95% confidence interval [CI] -1.7-6.9 and SC vs EA: mean difference 0.6 [95% CI] -3.6-4.8). Fewer number of women in the EA group used epidural analgesia (46%) than women in the MA group (61%) and SC group (70%) (EA vs SC: odds ratio [OR] 0.35; [95% CI] 0.19-0.67).

Conclusions

Acupuncture does not reduce women’s experience of labour pain, neither with manual stimulation nor with combined manual and electrical stimulation. However, fewer women in the EA group used epidural analgesia thus indicating that the effect of acupuncture with electrical stimulation may be underestimated. These findings were obtained in a context with free access to other forms of pain relief.

Trial registration

[Pain management in urology]

This article reviews aspects of postoperative and chronic pain management in urology patients. Continuous epidural techniques are recommended for extensive retroperitoneal und transperitoneal surgery due to its excellent analgesia and facilitation of enhanced recovery. In patients without regional analgesia techniques, intravenous or oral non-opioid analgesics should be combined with titration of fast acting opioids on an as-needed basis. Oral slow-release opioids are increasingly being used as part of systemic pain management although little evidence exists. Local wound infiltration and transcutaneous electrical nerve stimulation (TENS) treatment are simple and effective supplements for postoperative pain management. In 70-90% of urological cancer patients pain can be adequately relieved by consistent adherence to the WHO cancer pain recommendations. Additional pain relief approaches, such as radiation as well as psychosocial and spiritual needs of these patients have to be considered. In long-term treatment of non-cancer pain, effective use of opioids is not evidence-based. These patients often benefit from multimodal, interdisciplinary pain management comprising psychological and educational approaches as well as activating physiotherapy.

The evolution and practice of acute pain medicine

BACKGROUND

In recent years, the field of acute pain medicine (APM) has witnessed a surge in its development, and pain has begun to be recognized not merely as a symptom, but as an actual disease process. This development warrants increased education of residents both in the performance of regional anesthesia as well as in the disease course of acute pain and the biopsychosocial mechanisms that define interindividual variability.

REVIEW SUMMARY

We reviewed the organization and function of the modern APM program. Following a discussion of the nomenclature of acute pain-related practices, we discuss the historical evolution and modern role of APM teams, including the use of traditional, as well as complementary and alternative, therapies for treating acute pain. Staffing and equipment requirements are also evaluated, in addition to the training requirements for achieving expertise in APM. Lastly, we briefly explore future considerations related to the essential role and development of APM.

CONCLUSION

The scope and practice of APM must be expanded to include pre-pain/pre-intervention risk stratification and extended through the phase of subacute pain.

Acupuncture for postoperative pain in day surgery patients undergoing arthroscopic shoulder surgery

The purpose of this quasi-experimental study was to examine the effect of acupuncture on postoperative pain in day surgery patients undergoing arthroscopic shoulder surgery. Twenty-two participants scheduled to undergo arthroscopic shoulder surgery were included. The results showed that on postoperative day one pain decreased (-1.1) in patients receiving acupuncture compared to the control group in which pain increased (2.0), p=.014. Sleep quality was also significantly higher in the acupuncture group compared to the control group, p=.042. In conclusions, acupuncture seems to have a reducing effect on postoperative pain as well as increase sleep quality in day surgery patients undergoing arthroscopic shoulder surgery. In regards to application, nurses should be encouraged to use additional nonpharmacologic approaches like acupuncture in postoperative pain management, as this can be a part of the multimodal analgesic regimes to improve patients care.
