Risk factors for airway management after tracheal extubation in old patients / 中国基层医药

ABSTRACT

ObjectiveTo investigate the risk factors for airway management after tracheal extubation in old patients. Methods280 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. ResultsThe 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. ConclusionBMI≥25kg/m2 ,preoperative lung disease and without antagonist muscular relaxant were the main risk factors for dyspnea after tracheal extubation in old patients.
