胃管置入深度对胃肠减压疗效的Meta分析

目的：根据现有临床研究评价增加胃管插入深度对胃肠减压的有效性。方法检索CBM、CNKI、万方数据库、Cochrane、EMBASE、CINAHL、PubMed等数据库中的有关胃管插入深度对胃肠减压效果影响的中英文随机对照试验（RCT），提取数据并进行质量评价，数据分析采用RevMan5.2软件。结果共纳入20篇文献，共3507例患者。Meta分析结果显示：增加胃管置入深度可以降低中重度腹胀的发生率[OR=0.28，95%CI（0.24，0.33）]、增加置管后24 h引流液量[WMD=200.36，95%CI （95.37，305.35）]、缩短肠鸣音恢复时间[WMD=-23.98，95%CI （-30.09，-17.86）]。结论增加胃管的置入深度可以有效减轻腹胀、增加引流量、缩短肠鸣音的恢复时间。

A meta-analysis of the therapeutic effects of increasing insertion depth of nasogastric tube on gastrointestinal de-compression

Objective To evaluate the efficacy of increasing insertion depth of nasogastric tube in the treatment of gas-trointestinal decompression. Methods The randomized clinical trials（RCT） that compared the efficacy of increasing inser-tion depth of nasogastric tube in treatment of gastrointestinal decompression were researched from CBM,CNKI,Wangfang data,Cochrane,EMBASE,CINAHL,PubMed. After extracting data and assessing the quality of the included studies, meta-analysis was conducted using RevMan 5.2 software. Results Twenty RCTs including 3507 cases were included. Meta-analysis showed that increasing insertion depth of nasogastric tube significantly decreased occurring rate of moderate-severe abdominal distention[OR=0.28, 95%CI（0.24, 0.33）],significantly increased the 24 hours volume of drainage after nasogas-tric tube place [WMD=200.36, 95%CI （95.37, 305.35）] and significantly shortened the recovery time of bowel sounds [WMD=-23.98, 95%CI （-30.09,-17.86）]. Conclusions Increasing insertion depth of nasogastric tube can decrease oc-curring rate of moderate-severe abdominal distention, increase 24 hours volume of drainage after nasogastric tube place and shorten recovery time of bowel sounds.
