Risk factors for airway management after tracheal extubation in old patients

Abstract

Objective To investigate the risk factors for airway management after tracheal extubation in old patients. Methods 280 patients underwent general anesthesia were enrolled in the study. The procedure of anesthesia induction and maintenance were in the routine method. The patients were with tracheal extubation under clinical standards after operation. Dyspnea was recorded after tracheal extubation. They were divided into dyspnea group and general group. Twelve perioperative variables, ten variables in operation and six post-operative variables of two groups were compared respectively. Results The incidence of dyspnea after tracheal extubation was 8.6％. Analysis identified that obesity( BMI ≥25kg/m2 ), preoperative lung disease and without postoperative neostigmine were the significant risk factors for dyspnea. Conclusion BMI≥25kg/m2 ,preoperative lung disease and without antagonist muscular relaxant were the main risk factors for dyspnea after tracheal extubation in old patients.
