Abstract:
Objective To compare the effect of passive humidification and active humidification on artificial airway. Methods We collected all related RCTs from CNKI, Wangfang database, VIP database for the information of passive and active humidification of artificial airways, and its effects, rate of tube plugging, rate of pulmonary infection as outcome indicator by computer. Results We included 11 RCTs involved 1531 participants. The 95% CI were 0. 47(0. 3—0. 73,P =0. 000 9),1. 32(1. 01—1. 73,P =0. 04) and 0. 88 (0. 43—1. 78, P=0. 71 ) for passive and active humidification, satisfaction of humidification, inadequate humidification, and rate of tube plugging 0. 88 (0. 43—1. 78,P =0. 71), rate of pulmonary infection 0. 57 (0. 50—0. 90,P=0. 008). Conclusions Based on present RCTs in China, there is a significant increase in the humidifier′s performances in patients humidified with passive humidification during the upper airway, but this finding is limited by pediatric, neonatal and high-risk tube plugging groups. Further RCTs are necessary to examine the wider applicability of heat and moisture exchangers and their extended use.
