Effect of Acupuncture Combined with Blood-letting by a Three-edged Needle on 50 cases of Bell's Palsy at the Acute Stage

Objective:To observe clinical effects of acupuncture combined with blood-letting by a three-edged needle for treating Bell's palsy of wind-heat syndrome at the acute stage.Methods:One hundred patients were randomly divided into a treatment group(50 cases) treated by acupuncture plus blood-letting and a control group(50 cases) treated by simple acupuncture.Four courses of treatments were given in both groups.The main symptoms and signs were observed and clinical effects evaluated with scores after one week,2 weeks and one month of treatments respectively.Results:After treatment,the scores for symptoms and signs were significantly different from those before treatment in both groups(P<0.05 or P<0.01).After one month of treatment,the improvement of the symptoms and signs in the treatment group was more than that in the control group with a significant difference(P<0.05).Conclusion:Acupuncture plus blood-letting can produce good therapeutic effects on Bell's palsy of wind-heat syndrome at the acute stage.

Clinical Practice Guideline of Acupuncture for Bell's Palsy

Backgroud: Acupuncture is common used for Bell's palsy in clinic, however, recent systematic reviews all shows that there is no sufficient evidence to support the effectiveness of acupuncture for Bell's palsy because ofthe poor quality and heterogeneity. It's urgently necessary to develop a guideline of acupuncture for Bell's palsy based on principles of evidence-based medicine to optimize acupuncture treating,standardize outcomes evaluating and to improve the quality of acupuncture for patients with Bell's palsy under general circumstances.Objective: To improve the accuracy of diagnosing and managing Bell's palsy, optimize acupuncture treating and outcomes evaluating for patients with Bell's palsy, and to improve the quality of acupuncture for patients with Bell's palsy in most instances.Methods: This guideline was developed using an explicit and transparent a priori protocol based on supporting evidences and experts' consensus. The guideline developing Group followed the protocol through all stages of the development process: proposed clinical questions,searched clinical evidences, evaluated levels of evidences, developed recommendations, peer reviewed and consummated, and finally formed the draft of this guideline.Results:(1)The guideline development group made a Grade A recommendation that ①With a course of Bell's palsy within 3 months, the patients with mild facial palsy may be treated with any one of acupuncture, western drugs, or acupuncture combing with western drugs,whereas the patients with severe facial palsy may be treated with acupuncture or acupuncture combing with western drugs. With a course of more than 3 months, acupuncture is more suitable.②Acupuncture should be applied as early as possible for Bell's palsy.③The principle of selecting acupoints for Bell's palsy is to select local points, points of corresponding meridians and those according to differentiation. Generally,the points of yangming meridians are the main ones. ④The various methods of acupuncture and moxibustion are adopted for Bell's palsy,including filiform needling, moxibustion, electro-acupuncture, etc. Two or more methods are usually used together in clinical practice.(2) The development group formed expert consensus on the principles of acupuncture treatment for Bell' palsy. Bell's palsy is suitably treated according to the stages, differentiation and symptoms.
