摘要
Abstract
Objective To evaluate the clinical risk factors of prolonged mechanical ventilation after valve replacement surgery. Methods A total of 518 patients who underwent valve replacement between Jan 2010 and Aug 2011 were studied retrospectively. And the risk factors of prolonged mechanical ventilation ( ≥48 h) after valve replacement surgery were e-valuated. Results Prolonged mechanical ventilation occurred in 13.9% patients after valve replacement surgery. Univari-ate analysis showed that, patients' age, cardiac function, BNP level, ejection fraction, pulmonary artery pressure, concomitant CABG surgery, 1ABP usage, cardiopulmonary bypass time, aortic cross-clamp time, number of valve replacement, use of dopamine ≥10 ( kg·min) and use of epinephrine are related to prolonged mechanical ventilation after valve replacement surgery (P <0.05 orP<0. 01). Binary logistic regression analysis showed that, cardiac function, pulmonary artery pressure and use of dopamine ≥10 μg/( kg·min) are independently associated with prolonged mechanical ventilation after valve replacement surgery (P <0.05 or P <0.01). Conclusion Patients' cardiac function, pulmonary artery pressure and use of dopamine ≥10μg/( kg·min) are risk factors of prolonged mechanical ventilation after valve replacement surgery.关键词
