水胶体敷料预防压疮的Meta分析

Hydrocolloid dressings for preventing pressure ulcers： A Meta-analysis

目的评价使用水胶体敷料联合常规护理预防压疮的有效性。方法检索中英文可及数据库中关于评价水胶体敷料用于压疮预防的随机对照实验（RCT）和类实验研究。提取资料用Revman5．0软件进行数据处理和分析。结果共纳入17篇文献，1371例患者。Meta分析结果显示：存在压疮风险的患者，预防性使用水胶体敷料联合常规护理组比常规护理组压疮发生率低，RR=0．29，95％CI（0．18,0．46）；使用无创正压通气的患者，预防性使用水胶体敷料联合常规护理组比常规护理组压疮发生率低，RR=O．30，95％CI（0．18，0．52）。结论存在压疮风险的患者和使用无创正压通气的患者，预防性使用水胶体敷料联合常规护理能更有效的预防压疮。

Objective To evaluate the effects of hydrocolloid dressings with conventional care in the prevention of pressure ulcers. Methods Randomised controlled trials and quasi-randomised trials, which assessed the effects of hydrocolloid dressings in preventing pressure ulcers compared to conventional care were sought. Data were pooled using RevMan 5.0. Results 17 eligible trials were identified with a total of 1 371 study participants. Meta-analysis showed that：Compared to conventional care, conventional care and hydrocolloid dressings were effective for preventing pressure ulcers for patients at risk of pressure ulcers [RR=0.29,95%CI （0.18,0.46）] and using noninvasive positive pressure ventilator [RR=0.30,95%CI （0.18,0.52）. Conclusions Hydrocolloid dressings and conventional care can reduce the pressure ulcer incidence of patients at risk of pressure ulcer or using noninvasive positive pressure ventilator.
