Acupuncture versus titrated morphine in acute renal colic: a randomized controlled trial

Acupuncture for response and complete pain relief time of acute renal colic: Secondary analysis of a randomized controlled trial

Background

The integration of acupuncture with intramuscular injection of diclofenac sodium can expedite the onset of analgesia in treating acute renal colic caused by urolithiasis. However, it remains unclear whether acupuncture can accelerate pain relief constantly until complete remission. This study aimed to explore the extent to which acupuncture can expedite the onset time of response or complete pain relief in treating acute renal colic, and the predictive value of patient characteristics for treatment efficacy.

Methods

This secondary analysis utilized data from a prior randomized controlled trial. Eighty patients with acute renal colic were randomly assigned 1:1 to the acupuncture group or the sham acupuncture group. After intramuscular injection of diclofenac sodium, acupuncture or sham acupuncture was delivered to patients. The outcomes included time to response (at least a 50 % reduction in pain) and complete pain relief. Between-group comparison under the 2 events was estimated by Kaplan-Meier methodology. Subgroup analysis was performed utilizing the Cox proportional hazards model.

Results

The median response time and complete pain relief time in the acupuncture group were lower than those in the sham acupuncture group (5 vs 30 min, Log Rank P < 0.001; 20 min vs not observed, Log Rank P < 0.001, respectively). Hazard Ratios (HRs) for response across all subgroups favored the acupuncture group. All HRs for complete pain relief favored acupuncture, expect large stone and moderate pain at baseline. No interaction was found in either event.

Conclusion

Acupuncture can accelerate the response time and complete pain relief time for patients with acute renal colic, with the efficacy universally.

Methodology and findings of randomized clinical trials on pharmacologic and non-pharmacologic interventions to treat renal colic pain - a review

Introduction

Renal colic pain is considered one of the most excruciating pains ever experienced and ranks as one of the most common urological emergencies. Despite existing established recommendations, new therapies and their combinations are continuously being tested. The aim of this systematic review is to analyze and compare studies involving pharmacologic and non-pharmacologic interventions used in the treatment of renal colic pain.

Material and methods

This systematic review was conducted following the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Medline, Scopus, Cochrane Library, and Google Scholar were searched for relevant randomized controlled trials (RCTs) involving adult patients. The quality and results of the included studies were assessed and discussed.

Results

This review provides an extensive analysis of 71 identified RCTs. Opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, and dipyrone/metamizole have demonstrated effectiveness as single medications. Some evidence points to opioids having a potential disadvantage compared to others when used as a first-line single medication. Among the 63 studies exploring pharmacological therapy, 51 reported opioids utilization for rescue therapy in significant proportion of patients. Promising combination therapies involve the administration of an NSAID alongside opioids, ketamine, desmopressin, steroids, or nitric oxide. Conversely, spasmolytics, magnesium, and lidocaine exhibited limited or no additional effect. Noteworthy methodological shortcomings encompass a low pain threshold during participant recruitment and the reliance on pain reduction rather than complete pain elimination as an endpoint.

Conclusions

Frequent use of opioids as rescue medications in RCTs undermine their conclusions on effectiness of other therapeutics. Combination therapies should be considered as first choice in renal colic pain management. RCTs should define success of therapy as achieving complete or near-complete pain relief rather than pain reduction.

Clinical efficacy of acupuncture for pain relief from renal colic: A meta-analysis and trial sequence analysis

Background

This meta-analysis aimed at investigating the efficacy of acupuncture for relieving renal colic and reducing the risk of analgesic-related complications.

Methods

Randomized controlled trials (RCTs) comparing the efficacy of acupuncture (acupuncture group) with conventional interventions (control group) were screened from MEDLINE, EMBASE, Cochrane library databases, China Knowledge Network (CNKI), and Airiti Library till July 15, 2022. The primary outcome was the rate of effective pain relief (response rate), while secondary outcomes included the time of onset of pain relief, visual analog scale (VAS) at 30-60 min and risk of side effects.

Results

Thirteen eligible studies involving 1,212 participants published between 1992 and 2021 were analyzed. Compared with the control group, patients receiving acupuncture had a higher overall response rate [risk ratio (RR) = 1.12, 95% CI: 1.05-1.19, p = 0.0002, I ² = 41%, 1,136 patients] (primary outcome) and a faster pain relief [MD = -10.74 min, 95% CI: -12.65 to -8.82, p < 0.00001, I ² = 87%, 839 patients]. Patients receiving acupuncture had a lower pain score [MD = -0.65, 95% CI: -1.09 to -0.21, p = 0.21, I ² = 55%, 327 patients] and risk of side effects (RR = 0.11, 95% CI: 0.04-0.26, p < 0.00001, I ² = 0, 314 patients) compared to those receiving conventional interventions. Results from trial sequence analysis revealed sufficient evidence supporting the beneficial effects of acupuncture on response rate, time to pain relief, and pain score at 30-60 min.

Conclusion

Compared with conventional analgesic-based interventions, acupuncture can more efficiently relieve renal colic with fewer adverse effects. The limited number and quality of included studies warrant more clinical RCTs to support our findings.

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.

Efficacy and Safety of Acupuncture in Renal Colic Caused by Urinary Calculi in Adults: A Systematic Review and Meta-Analysis

Background

Acute renal colic caused by urinary calculi has a considerable impact on the quality of life. Pain relief is the primary goal in the management of patients with acute renal colic caused by urinary calculi. At present, there is no systematic evaluation of the efficacy and safety of manual acupuncture in the treatment of acute renal colic caused by urinary calculi in adults.

Objective

To evaluate the efficacy and safety of manual acupuncture in the treatment of acute renal colic caused by urinary calculi in adults.

Methods

Databases of PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Medical, VIP Database for Chinese Technical Periodicals (VIP), and China Biomedical Literature (SinoMed) were searched for literature and other randomized controlled registration platforms. We searched to identify the relevant randomized controlled trials from the establishment of the database to February 9, 2022. Only randomized controlled trials (RCTs) of manual acupuncture as the therapy for acute renal colic caused by urinary calculi in adults were included, whether or not the blind method is used. The patients were adults diagnosed with urinary calculi and renal colic. The control group was treated with commonly used analgesics and antispasmodics. The experimental group was treated with acupuncture as a monotherapy or as an adjuvant therapy (manual acupuncture combined with analgesics and antispasmodics). Two review authors independently assessed titles and abstracts for relevance and extracted data on study design, participants, interventions, and outcomes from potentially relevant articles. Cochrane risk bias assessment tool was used to evaluate the quality of the included study, and RevMan5.4 software was used for meta-analysis. Our primary outcomes were response rate and time duration before pain remission. Secondary outcomes were the time of complete pain relief, pain variation, need for rescue analgesia, and adverse events.

Results

Out of 1123 records identified, 15 were found to be of relevance to this study, and 1210 participants were included in the meta-analysis. The meta-analysis of the results shows that, in terms of response rate, compared with the control group, acupuncture as a monotherapy seems to have a slight advantage (RR = 1.10 (95% CI: 1.03, 1.18), I² = 28%, P=0.004), while acupuncture as an adjuvant therapy has no advantage (RR = 1.06 (95% CI: 0.95, 1.20), I² = 77%, P=0.30). In terms of duration before pain relief, acupuncture as a monotherapy had an advantage over the control group (MD = −10.28(95% CI: −14.40, −6.17), I² = 93%, P < 0.00001). Acupuncture as a monotherapy was similar to positive medication in terms of complete pain relief (MD = −7.13 (95% CI: −20.19, 5.94), I² = 95%, P=0.28). Pain variation: VAS scores at 10 min, acupuncture as a monotherapy (MD = −2.47 (95% CI: −3.40, −1.53), I² = 84%, P < 0.00001) or as an adjuvant therapy (MD = −3.38 (95% CI: −4.33, −2.43), I² = 60%, P < 0.00001) was better than the control group. VAS scores at 30 min, compared with the control group, there was no difference between acupuncture as a monotherapy (MD = −0.27 (95% CI: −1.43, 0.88), I² = 88%, P=0.64) and acupuncture as an adjuvant therapy (MD = −1.17 (95% CI: −3.15, 0.81), I² = 96%, P=0.25). VAS scores at 60 min, compared with the control group, there was no difference in the acupuncture as a monotherapy (MD = 0.58 (95% CI: −0.28, 1.45), I² = 77%, P=0.19), while acupuncture as an adjuvant therapy was better (MD = −1.22 (95% CI: −1.93, −0.51), I² = 72%, P=0.0007). VAS scores at 120 min, there was no difference in acupuncture as a monotherapy compared to the control group (MD = −0.24 (95% CI:−1.22, 0.75), I² = 0, P=0.64). One study reported on rescue analgesia. Fewer adverse events occurred in the experimental group compared to the control group.

Conclusion

In the course of manual acupuncture treatment of acute renal colic caused by urinary calculi in adults, available evidence suggests that manual acupuncture is as effective as positive treatment drugs, either as a monotherapy or as an adjunctive therapy, with the advantage of acupuncture being its rapid onset of action. However, the number of existing clinical studies is small, and the quality of evidence is generally low, so it is recommended to use it with caution. In order to further verify the above conclusions, more high-quality clinical RCTs need to be carried out. Trial Registration. The present review protocol was registered with the International Prospective Register of Systematic Reviews (CRD42019134900).

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.

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.

Acupuncture in the emergency department for pain management: A BraveNet multi-center feasibility study

PURPOSE

Pain accounts for up to 78% of emergency department (ED) patient visits and opioids remain a primary method of treatment despite risks of addiction and adverse effects. While prior acupuncture studies are promising as an alternative opioid-sparing approach to pain reduction, successful conduct of a multi-center pilot study is needed to prepare for a future definitive randomized control trial (RCT).

METHODS

Acupuncture in the Emergency Department for Pain Management (ACUITY) is funded by the National Center for Complementary and Integrative Health. The objectives are to: conduct a multi-center feasibility RCT, examine feasibility of data collection, develop/deploy a manualized acupuncture intervention and assess feasibility/implementation (barrier/facilitators) in 3 EDs affiliated with the BraveNet Practice Based Research Network.Adults presenting to a recruiting ED with acute non-emergent pain (e.g., musculoskeletal, back, pelvic, noncardiac chest, abdominal, flank or head) of ≥4 on a 0-10-point Numeric Rating Scale will be eligible. ED participants (n = 165) will be equally randomized to Acupuncture or Usual Care.At pre-, post-, and discharge time-points, patients will self-assess pain and anxiety using the Numeric Rating Scale. Pain, anxiety, post-ED opioid use and adverse events will be assessed at 1 and 4 weeks. Opioid utilization in the ED and discharge prescriptions will be extracted from patients' electronic medical records.Acupuncture recipients will asked to participate in a brief qualitative interview about 3 weeks after their discharge. ED providers and staff will also be interviewed about their general perspectives/experiences related to acupuncture in the ED and implementation of acupuncture in ACUITY.

RESULTS

Recruitment began on 5/3/21. As of 12/7/21: 84 patients have enrolled, the responsive acupuncture intervention has been developed and deployed, and 26 qualitative interviews have been conducted.

CONCLUSION

Successful conduct of ACUITY will provide the necessary framework for conducting a future, multi-center, definitive RCT of acupuncture in the ED.

Immediate acupuncture with GB34 for biliary colic: protocol for a randomised controlled neuroimaging trial

INTRODUCTION

As the main manifestation of gallstone disease, biliary colic (BC) is an episodic attack that brings patients severe pain in the right upper abdominal quadrant. Although acupuncture has been documented with significance to lead to pain relief, the immediate analgesia of acupuncture for BC still needs to be verified, and the underlying mechanism has yet to be covered. Therefore, this trial aims first to verify the immediate pain-alleviation characteristic of acupuncture for BC, then to explore its influence on the peripheral sensitised acupoint and central brain activity.

METHODS AND ANALYSIS

This is a randomised controlled, paralleled clinical trial, with patients and outcome assessors blinded. Seventy-two patients with gallbladder stone disease presenting with BC will be randomised into a verum acupuncture group and the sham acupuncture group. Both groups will receive one session of immediate acupuncture treatment. Improvements in patients' BC will be evaluated by the Numeric Rating Scale, and the pain threshold of acupoints will also be detected before and after treatment. During treatment, brain neural activity will be monitored with functional near-infrared spectroscopy (fNIRS), and the needle sensation will be rated. Clinical and fNIRS data will be analysed, respectively, to validate the acupuncture effect, and correlation analysis will be conducted to investigate the relationship between pain relief and peripheral-cerebral functional changes.

ETHICS AND DISSEMINATION

This trial has been approved by the institutional review boards and ethics committees of the First Teaching Hospital of Chengdu University of Traditional Chinese Medicine, with the ethical approval identifier 2019 KL-029, and the institutional review boards and ethics committees of the First People's Hospital of Longquanyi District, with the ethical approval identifier AF-KY-2020071. The results of this trial will be disseminated through peer-reviewed publications and conference abstracts or posters.

¿Qué es la medicina alternativa, complementaria e integrativa?

El concepto de medicina alternativa fue creado por la medicina occidental para identificar prácticas médicas diferentes a la medicina convencional, tales como la medicina tradicional china y acupuntura, homeopatía, terapia neural, medicina osteopática y quiropráctica, medicina ayurveda y la medicina tradicional indígena, que también tienen fundamentos filosóficos, científicos y terapéuticos. Desafortunadamente, con el tiempo se estableció la creencia de que la medicina alternativa comprende todas las prácticas médicas que no son parte de la medicina convencional, lo que ha causado muchas inexactitudes y controversias. La medicina surgió como necesidad de auto preservación del ser humano y que considera a la salud como bienestar completo y a la enfermedad, como pérdida de esta condición. A lo largo de su evolución han emergido diversas racionalidades y algunas de ellas se han convertido en sistemas médicos. La medicina convencional se estructuró en Occidente, fundamentada en racionalidades médicas existentes para la época y enfocada en modificar la enfermedad, lo que resultó en marcadas diferencias conceptuales con sistemas de tratamiento ya existentes que se centraban en el individuo y en modificar los procesos de la enfermedad. Todos los sistemas médicos han generado un impacto en diversos campos sociales. Asimismo, han surgido tendencias y estrategias de integración de la medicina convencional con otros sistemas médicos comoLa electroacupuntura de Voll, la homotoxicología, el balance polar electromagnético, la antroposofía, la sintergética y la biofotónica. Actualmente se considera que el objetivo de la medicina es integrar y complementar conocimientos de diferentes racionalidades médicas dentro del concepto de una sola medicina. Teniendo en cuenta lo anterior, el objetivo del presente artículo es clarificar los conceptos de las diferentes formas de medicina, plantear algunas definiciones al respecto, y proponer una definición de medicina alternativa, complementaria e integrativa.

Acupuncture versus Lornoxicam in the Treatment of Acute Renal Colic: A Randomized Controlled Trial

Objective

To compare the analgesic efficacy and safety of acupuncture and lornoxicam in acute renal colic (ARC).

Design, Setting, Participant

A randomized, double-blind, parallel-controlled, single-centered trial was conducted at Susong County People’s Hospital from October 2019 to November 2020. Eighty-four patients with ARC were randomly divided into lornoxicam group (Group L) and acupuncture group (Group A). Group A was treated with acupuncture at Sanyinjiao (SP6), Yinlingquan (SP9) and normal saline, and Group L was treated with sham acupuncture at SP6, SP9 and lornoxicam.

Main Outcome Measures

Visual analogue scale (VAS) scores and adverse reactions such as nausea and dizziness were recorded within 5, 10, 15, 20 and 40 minutes after treatment. The main outcome of this study was the short-term effective (STE) rate, the secondary outcome was the onset time, and the safety index was incidence of adverse reactions.

Results

A total of 80 patients completed this study, including 41 patients (21 males and 20 females) in Group L and 39 patients (21 males and 18 females) in Group A. Group A exhibited lower scores versus group L after treatment (P < 0.05). The overall STE of group L was 61.00% (25/41), significantly lower than group A [84.62% (33/39)] (P < 0.001). There was no difference in the incidence of adverse reactions between group A [2.6% (1/39)] and group L [7.3% (3/41)] (P = 0.616). The ordered logistic regression analysis showed patients receiving acupuncture therapy are more likely to be cured [OR = 2.887, 95% CI: (1.190, 7.000), P = 0.019].

Conclusion

Acupuncture at SP6, SP9 and intramuscular injection of lornoxicam can effectively and safely relieve ARC, but the former has faster and better analgesic effect. Moreover, the incidence of adverse reactions was similar between the two treatments. This acupuncture therapy is recommended as a complementary therapy for ARC.

Lessons Learned in Teaching Battlefield (Ear) Acupuncture to Emergency Medicine Clinicians

Background: Acupuncture, in general, is being proclaimed as an alternative analgesic amid the opioid crisis, and along with this, within emergency departments (EDs) there is a specific interest in a form of ear acupuncture called Battlefield Acupuncture (BFA). It is expected that BFA will be used more widely in emergency medicine as it is easy to learn and can be applied both promptly and easily. Teaching programs will be required to sustain this increased demand and upskill emergency clinicians in this skill. Objectives: This article provides experiences and recommendations, based on faculty experiences from teaching BFA in Australia to ED clinicians combined with formal participant feedback. Main Points: BFA courses were adjusted to suit ED doctors and nurses, along with their unique case mix and associated challenging environment. The content of the BFA courses included evidence, pain indications, contraindications, application, safety, mechanism of action, and how to negotiate barriers of credentialing. Workshops used the latest and most effective teaching methods that encompassed problem-based learning, infotainment, simulation, "four stage skills teaching," and "teaching on the run." Conclusion: It is hoped that the experiences gained, and lessons learned in educating this new frontier of BFA to emergency clinicians will assist others in teaching BFA and its related techniques as a viable analgesic alternative in emergency medicine.
