Network meta-analysis of airway humidification in patients with non-mechanical ventilation after domestic gastrectomy

Abstract

Objective To evaluate the therapeutic effects of various airway humidification methods to prevent pulmonary infection in non-mechanical ventilation patients by network meta-analysis. Methods The Pubmed, Embase, Web of Science, Wanfang data, and CNKI databases were searched and a randomized controlled trial (RCT) was developed for the method of humidification in non-mechanical ventilation patients after domestic air-surgery. The staff independently screened the literature, extracted the data, and used the stata14.0 software for network meta-analysis. Results In the 3 342 articles, 25 of them were included in the Meta-analysis, involving 6 methods of airway humidification. The order of effectiveness: first place in artificial nose, second in venturi humidification device, third in continuous atomization, Intermittent atomization ranked fourth, continued to drop into the fifth place, intermittently dropped into the sixth position of humidification. Conclusion The effectiveness of artificial nose device and venturi humidification device has been gradually recognized by domestic counterparts. Meta analysis shows that it is effective in preventing lung infection and worth promoting.
