ABSTRACT
Objective To analyze the risk factors leading to prolonged mechanical ventilation following valve replacement surgery with the purpose of improving the management of these patients.Methods The risk factors of prolonged mechanical ventilation at preoperative,operative and postoperative clinical data of 307 patients who underwent valve replacement surgery were retrospectively analyzed.Binary Logistic regression model was used to assess the factors.Results The time of mechanical ventilation after valve replacement surgery was (15 ± 35) h,and 31.6% (97/307) of these patients underwent prolonged mechanical ventilation (> 8 h).Age ≥ 65 years (P =0.003),smoker (P =0.024),left ventricular ejection fraction (LVEF) preoperative (P =0.002),duration of operation (P =0.000),aortic block time (P =0.046),cardiopulmonary bypass time (P =0.030),number of replaced valve (P =0.001),volume of postoperative chest drainage (P =0.000) and postoperative complications (P =0.010) were risk factors of prolonged mechanical ventilation.Logistic regression analysis showed that LVEF (P =0.026),duration of operation(P =0.037),aortic block time (P =0.001),cardiopulmonary bypass time (P =0.013),number of replaced valve (P =0.017),volume of postoperative chest drainage (P =0.020) and postoperative complications (P =0.014) had extremely affection.Conclusions Greater importance should be attached to healthcare education,early treatment to avoid multivalvular involvement,preoperative heart function regulation,lower duration of operation especially aortic block time and cardiopulmonary bypass time,lower postoperative chest drainage and better preservation of organs during operation to decrease the rate of prolonged mechanical ventilation and optimize the clinical quality.
