Acupuncture-Associated Vasovagal Response: Revised Terminology and Hospital Experience

Practice recommendations for physiotherapists in Canada managing adverse events associated with acupuncture

In Canada, acupuncture is a regulated medical practice that involves inserting thin needles at specific points on the body to alleviate pain and other health conditions. Acupuncture is a controlled act in physiotherapy practice. Therefore, physiotherapists who incorporate acupuncture into their practice should have the necessary education and roster this controlled act with the regulatory college in their province. Although acupuncture can be helpful, potential complications can arise, ranging from minor bruising to life-threatening conditions such as pneumothorax and cardiac tamponade. This article provides information on the potential adverse effects of acupuncture and provides recommendations for physiotherapists regarding prevention and management of any incidents that may arise during treatment.

A Biophysical Model for Cardiovascular Effects of Acupuncture-Underlying Mechanisms Based on First Principles

According to recent translations by medical professionals of the foundational texts of Chinese Medicine, the acupuncture channel system can be reconciled with the neurovasculature. From there, the underlying mechanisms of the effects of acupuncture can be drawn from established physiology and known physical laws. A large body of research has been carried out using cardiovascular markers to measure the effects of acupuncture. Three of these parameters are re-viewed and explored anew in detail. The focus is on changes in microcirculation, blood pressure, and heart rate variability. The physiological mechanisms accounting for the observed changes are proposed to be ascending vasodilatation, resetting of the baroreceptor reflex, and re-organization of heart beating patterns around intrinsically assigned attractor sets.

Management strategies for the treatment and prevention of postoperative/postdischarge nausea and vomiting: an updated review

Postoperative nausea and vomiting (PONV) and postdischarge nausea and vomiting (PDNV) remain common and distressing complications following surgery. The routine use of opioid analgesics for perioperative pain management is a major contributing factor to both PONV and PDNV after surgery. PONV and PDNV can delay discharge from the hospital or surgicenter, delay the return to normal activities of daily living after discharge home, and increase medical costs. The high incidence of PONV and PDNV has persisted despite the introduction of many new antiemetic drugs (and more aggressive use of antiemetic prophylaxis) over the last two decades as a result of growth in minimally invasive ambulatory surgery and the increased emphasis on earlier mobilization and discharge after both minor and major surgical procedures (e.g. enhanced recovery protocols). Pharmacologic management of PONV should be tailored to the patient’s risk level using the validated PONV and PDNV risk-scoring systems to encourage cost-effective practices and minimize the potential for adverse side effects due to drug interactions in the perioperative period. A combination of prophylactic antiemetic drugs with different mechanisms of action should be administered to patients with moderate to high risk of developing PONV. In addition to utilizing prophylactic antiemetic drugs, the management of perioperative pain using opioid-sparing multimodal analgesic techniques is critically important for achieving an enhanced recovery after surgery. In conclusion, the utilization of strategies to reduce the baseline risk of PONV (e.g. adequate hydration and the use of nonpharmacologic antiemetic and opioid-sparing analgesic techniques) and implementing multimodal antiemetic and analgesic regimens will reduce the likelihood of patients developing PONV and PDNV after surgery.

Auricular Acupuncture Associated with Reduced Waist Circumference in Overweight Women-A Randomized Controlled Trial

Obesity and subsequent ill health have reached epidemic proportions in developed countries, and many developing countries are on the same trajectory. Weight loss and sustaining a healthy weight have posed a significant challenge for individuals, patients, health-care providers, and public health experts. The literature suggests that dietary advice and lifestyle changes alone have limited sustainable impact for those who are seeking to achieve a healthy weight. Supplementary techniques to control weight, such as acupuncture and auricular acupuncture (AA), have shown mixed results and failed to clearly demonstrate a conclusive impact. This study aimed to provide clarity about the impact of AA on weight loss via a randomized controlled trial. Data were collected from patients to identify measurable girth reduction, weight loss, dietary choices, and mood changes over seven weekly sessions of AA (n = 30) versus sham needle as control (n = 28). Results demonstrated a large and highly significant AA treatment effect for reduced waist circumference over the course of the seven-week intervention. While the treatment effect for weight loss and BMI was not significant, this negative result may have been mediated by the relatively short duration of the study. Results also demonstrated a significant mood improvement across participants in both the AA intervention and control group as the intervention progressed. Further studies are required to determine if the reduction in waist circumference is driven specifically by the AA alone or in conjunction with improved mood. The results also have potentially significant implications for healthcare delivery in the fight against overweight and obesity.

TA pharmacopuncture as a primary and independent treatment for frequent sprains occurring over 9 months in a patient with needle sickness: Case report

RATIONALE

Sprains, stretching or tearing of ligaments are common injuries. Clinicians should try to prevent acupuncture-associated vasovagal responses (AAVR) when treating patients with such injuries. In this study, we report the treatment of frequent sprains of various body parts in a patient with a history of AAVR using only TA (a 7-herb extract consisting of Scutellaria baicalensis, Phellodendron amurense, Pulsatilla koreana, Sophora tonkinensis, Aucklandia lappa, Aquilaria agallocha, and Carthamus tinctorius L.) pharmacopuncture.

PATIENT CONCERNS

The patient was a 47-year-old woman who was injured 23 times in 9 months. The injuries occurred in the knees, thumb, wrist, ankle, and low back region due to overextension during physical activity or frequent exercise. This patient had great fear of acupuncture after fainting due to her experience with a previous fire needling on an ankle sprain 18 years ago. Therefore, she did not want to undergo conventional acupuncture, including needle retention.

DIAGNOSES

With the exception of the bruising and sprain of a knee occurring over 1 week after onset at the initial visit, the injuries were diagnosed as acute sprains of grade 1 with pain without range of movement limitation in various parts of the knee, ankle, thumb, and lower back. Time to onset of these injuries was within 3 days.

INTERVENTIONS

The patients received only TA pharmacopuncture at 4 to 6 ouch points (ashi points). The patient returned to work immediately after the conclusion of treatment without any posttreatment such as infrared and hot pack which can help absorbing the extract and calming the injection site.

OUTCOME

The treatment was usually completed within 4 sessions, and led to a reduction in pain (visual analog scale [VAS] score of 1). In the absence of mild swelling and warmth or when there was mild pain (VAS score <3) in the affected area, the patient reported reduced pain and smoother joint movement immediately after 1 to 2 sessions.

LESSONS

Although our report is a single case study, our results indicate that TA pharmacopuncture can be effective in treating various acute sprains and is a potential acupuncture method for the treatment of patients with AAVR.

Oriental herbal medicine and moxibustion for polycystic ovary syndrome: A meta-analysis

BACKGROUND

Polycystic ovary syndrome (PCOS) is one of the most common disorders of reproductive endocrinology in women of reproductive age. Lifestyle intervention and oral contraceptives are the first-line treatments for PCOS. Recent studies have suggested that complementary and alternative medicine (CAM) therapies including acupuncture, herbal medicine, and mind-body therapy have the potential to alleviate the symptoms and/or pathology of PCOS and to improve the quality of life of women with PCOS. This meta-analysis aimed to quantitatively summarize the efficacy and safety of moxibustion combined with oriental herbal medicine (OHM), common CAM therapies, for treating PCOS.

METHODS

Four databases were searched from their inception to June 22, 2018. Randomized controlled trials (RCTs) and quasi-RCTs using both OHM and moxibustion as experimental intervention, and western medication (WM) as control intervention were included. Studies involving OHM plus moxibustion combined with WM as the experimental intervention were also included. The quality of included studies was assessed using risk of bias tool.

RESULTS

Owing to the heterogeneity of reporting, meta-analysis was only performed for pregnancy rate, rate of normal biphasic basal body temperature (BBT), and total effective rate (TER). The results showed that compared to the WM group, the OHM combined with moxibustion group was associated with significantly higher pregnancy rate (risk ratio [RR] 1.95, 95% confidence interval [CI] 1.55-2.47; I = 0%), normal biphasic BBT rate (RR 1.66, 95% CI 1.34-2.05; I = 0%), and TER (RR 1.19, 95% CI 1.08-1.31; I = 0%). When OHM combined with moxibustion was used as an adjunctive therapy to WM, pregnancy rate (RR 1.65, 95% CI 1.29-2.11; I = 0%), and TER (RR 1.35, 95% CI 1.13-1.61; I = 43%) were significantly higher than those of the WM group.

CONCLUSION

According to current evidence, OHM combined with moxibustion might be beneficial for treating PCOS. Moreover, the treatment might improve the therapeutic effects of conventional WMs including clomiphene citrate, oral contraceptives, and/or metformin. However, the findings should be interpreted with caution, owing to poor methodological quality of the included studies. Further larger, high-quality, rigorous RCTs should be conducted in this regard.
