Abstract: Objective To select and obtain relevant evidence on airway management of critically-ill adults at home and abroad, and to provide reference for clinical management. Methods Evidence-based issues in accordance with the PIPOST model were identified and we searched UpToDate, Cochrane library, BMJ, NGC, PubMed, SCCM, NICE, JBI, CINAHL, Medline, CNKI, CBM Database and Wanfang Database for eligible literature. Two evidence-based researchers independently evaluated the quality of the included literature, extracted and synthesized evidence. Results There were 25 articles including 1 advanced clinical decision support, 7 guidelines, 8 systematic evaluations, 5 evidence summaries and 4 expert consensus. A total of 44 pieces of best evidence was summarized from 7 aspects of airway evaluation, airway attraction timing, cuff pressure management, airway humidification, airway suctioning, tracheostomy stoma care, and oral nursing. Conclusion In clinical practice, medical staff should strengthen the training of evidence-based knowledge of airway management. Dynamical assessment of airway conditions, the timing of airway suction, cuff pressure management and airway humidification, precautions for airway suction, and standardized tracheostomy care process, and oral care of patients are conducive to the recovery of patients.
