目的 :为提高临床麻醉科研设计水平 ,对中国有关麻醉的临床研究状况进行初步调查。方法 :选择国内 2种麻醉领域核心期刊中华麻醉学杂志、临床麻醉学杂志 ,用手工检索调查 1994～ 1998年间临床研究论文。结果 :84期共载临床研究论文 2 5 2 8篇 ,RCT6 5 0篇 (占 2 5 7% )。采用盲法 2 9篇 (占 4 46 % ) ,392篇 (6 0 3% )比较组间可比性 ,对试验结果进行统计学处理共 387篇 (占 5 9 5 % ) ,其中 119篇 (占 30 7% )统计方法有错。结论 :国内近年来临床麻醉领域RCT数量不断增多 ,以中、小样本试验为主 ,盲法采用率较低。RCT质量仍有待提高。
OBJECTIVE: To investigate the clinical design of anesthesia in clinical practice and conduct a preliminary investigation on the clinical research of anesthesia in China. Methods: To select the 2 core journals of anesthesia field of Chinese Journal of Anesthesiology, Journal of Clinical Anesthesiology, manual retrieval of clinical research papers from 1994 to 1998. Results: A total of 858 clinical papers were published in 84 phases, and 50 articles were RCT6 (25.7%). A total of 387 (accounting for 59.5%) of the test results were comparied with 29 (46%) and 392 (603%) blinded methods, of which 119 (accounting for 30 7%) The statistical method is wrong. CONCLUSION: The number of RCTs in clinical anesthesia in China has been continuously increasing in recent years. The medium and small sample trials are the main ones, and the blind adoption rate is low. RCT quality still needs to be improved.
