激光针灸治疗儿童哮喘:对随机对照试验的系统性综述
2012/10/11
摘要
背景和目的:激光针灸已经被推荐作为哮喘的一种治疗手段。该技术具有无创性,尤其适合儿童哮喘的治疗。然而,数项临床试验的结果存在不一致。本文对有关激光针灸治疗儿童期哮喘的有效性进行系统性综述。
方法:对2012年2月之前的Cochrane Library、Medline、EMBASE、AMED、CINAHL和2个中文数据库(CNKI和VIP)进行检索。入选研究激光针灸治疗儿童哮喘的随机对照试验(RCT)。无语言限制。3名作者独立对研究进行筛选、提取数据并对试验的质量进行评价。
结果:共找到13项研究,其中3项包含有176名患者的研究满足入选标准。入选的RCT质量较低。一项平行分组设计的RCT显示正面结果,而两项交叉设计的RCT结果为负面。不同研究在患者类型、干预措施和转归指标上存在一定差异。由于临床和方法学上存在明显异质性,因而未对其进行荟萃分析。
结论:RCT数量和总体的样本量还很小;方法学质量较低。因此,可以认为目前尚未有充分的证据显示,激光针灸对儿童哮喘无效。有必要进行更为严格设计的临床试验,对激光针灸治疗儿童哮喘的疗效进行研究。

Abstract
BACKGROUND AND OBJECTIVES:Laser acupuncture has often been recommended as a treatment of asthma. The technique is noninvasive, and seems particularly suitable for children. However, the results from several clinical trials are contradictory. The objective of this review was to assess the effectiveness of laser acupuncture in the treatment of childhood asthma.
METHODS:Literature searches of electronic database were conducted in The Cochrane Library, Medline, EMBASE, AMED, CINAHL, and two Chinese literature databases (CNKI and VIP) up to February 2012. Randomized controlled trials (RCTs) testing laser acupuncture for asthma in children were included. No language restrictions were applied. Three authors independently selected articles, extracted data, and assessed trial quality.
RESULTS:Our searches identified 13 potential eligible studies, of which three with a total number of 176 patients met our inclusion criteria. The quality of included RCTs were low. One RCT with a parallel group design showed positive results, while two crossover RCTs generated negative results. There was variation in the type of patients, the interventions, and outcome measures. Because of the significant clinical and methodological heterogeneity, no meta-analysis was performed.
CONCLUSIONS:The number of RCTs and their total sample sizes are small; and their methodological quality is low. Therefore, no compelling evidence exists to suggest that laser acupuncture is not an effective treatment for childhood asthma. Further rigorous studies are warranted.
