体外循环术后患者ICU停留时间延长及危险因素的调查研究
Risk factors for prolonged intensive care unit stays in patients after cardiac surgery with cardiopulmonary bypass:A retrospective observational study
摘要
Abstract
Objectives:Patients after cardiac surgery with cardiopulmonary bypass(CPB)require a stay in the ICU postoperatively.This study aimed to investigate the incidence of prolonged length of stay(LOS)in the ICU after cardiac surgery with CPB and identify associated risk factors.Methods:The current investigation was an observational,retrospective study that included 395 ICU patients who underwent cardiac surgery with CPB at a tertiary hospital in Guangzhou from June 2015 to June 2017.Data were obtained from the hospital database.Binary logistic regression modeling was used to analyze risk factors for prolonged ICU LOS.Results:Of 395 patients,137(34.7％)had a prolonged ICU LOS(＞72.0 h),and the median ICU LOS was 50.9 h.Several variables were found associated with prolonged ICU LOS:duration of CPB,prolonged mechanical ventilation and non-invasive assisted ventilation use,Pa02/Fi02 ratios within 6 h after sur-gery,type of surgery,red blood cell infusion during surgery,postoperative atrial arrhythmia,post-operative ventricular arrhythmia(all P＜0.05).Conclusions:These findings are clinically relevant for identifying patients with an estimated prolonged ICU LOS,enabling clinicians to facilitate earlier intervention to reduce the risk and prevent resulting delayed recovery.关键词
