Abstract:
Objective:To evaluate the effect of aerosol inhalation and airway dripping for airway humidification of patients with tracheotomy, and explore airway humidification methods suitable for China's national conditions.Methods:The documents published from January 2010 to October 2020 in The Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI) , Wanfang Data and VIP were searched by computer, including randomized controlled trials (RCTs) on the application of aerosol inhalation and airway dripping as a method of airway humidification in patients with tracheotomy. Two researchers used the quality evaluation method of Cochrane Handbook (5.1.0.) to rigorously evaluate the quality of the documents and extract data, and conducted a meta-analysis of the documents that met the quality standards.Results:A total of12 RCTs were included, with a total of 1 010 patients. The results of meta-analysis showed that the sputum viscosity in the aerosol inhalation group was lower than that in the airway dripping group [ RR=0.29, 95% CI (0.21, 0.40) , P<0.01], the incidences of airway mucosal injury, irritating dry cough and lung infection also decreased [ RR=0.34, 95% CI (0.23, 0.51) , P<0.01; RR=0.24, 95% CI (0.16, 0.38) , P<0.01; RR=0.48, 95% CI (0.38, 0.61) , P<0.01], the airway humidification effect was better than that of the airway dripping group [ RR=0.1.34, 95% CI (1.23, 1.45) , P<0.01]. Conclusions:The application of aerosol inhalation to humidify the airway in patients with tracheotomy can significantly reduce the sputum viscosity, airway mucosal injury, irritating dry cough, and the lung infection, and achieve a good airway humidification effect.
