Analysis Of Related Factors Of Complications After Cardiac Valve Replacement

Objective: A retrospective analysis of perioperative data of patients in Suining area who underwent cardiac valve replacement was conducted to learn the occurrence of postoperative complications as well as risk factors attribute to these complications,to further improve the level of perioperative management and to prevent or reduce the postoperative complications of cardiac valve replacement,by which means we can provide some reference basis and promote the rapid recovery of patients after cardiac valve replacement.Methods: The clinical data of patients underwent heart valve replacement in Suining Central Hospital from January 2014 to December 2017 were collected.t-test was used for measuring data,Chi-square test was used forcategorical measure,rank sum test was used for ordered counting data,and the indexes with statistical significance of single factor analysis were analyzed by binary Logistic multi-factor analysis.Results: In a total of 184 patients,47 cases of pulmonary infection,25.54% of the incidence rate,25 cases of AKI,9.24% of LCOS,17 cases of low-heart-displacement syndrome,9.24% of the patients with LCOS,and 5.98% of postoperative bleeding.The incidence of arrhythmia in 10 cases was 5.43%,and the incidence rate was 4.35% in 8 cases after operation.One-factor analysis suggested that the time of cardiopulmonary bypass,the time of the aortic cross-blocking,the mode of operation,the time of operation,the amount of red suspended,the amount of the input plasma,the sex,the auxiliary time of the ventilator were the procedure.Potential risk factors of pulmonary infection(P <0.05);sex,pre-operative myocardiac value,combined hypertension,in vitrothe time of the loop,the time of the aortic cross-blocking,the time of operation,the potential risk factors of the acute renal failure(P <0.05),the time of the extracorporeal circulation,the time of the aortic cross-blocking,the auxiliary time of the ventilator,The post-operative arrhythmia(ventricular arrhythmia)is a potential risk for low-heart-displacement syndrome.(P <0.05).Multi-factor analysis: pre-operative combined with COPD(OR = 9.724,95% CI 1.370-69.037,P = 0.023),cardiopulmonary bypass time(OR = 8.920,95% CI 1.424-55.873,P = 0.019),operative time(OR = 4.874,95% CI 1.462-16.252,P = 0.010),ventilator-assisted time(OR = 16.639,95% CI 3.144-88.056,P = 0.001)The stay time of),ICU(OR=1.032,95%CI 1.031,1.052,P < 0.001)was an independent risk factor for postoperative pulmonary infection(P < 0.05).The independent risk factors of acute renal function injury were the input of red suspension(OR=1.001,95%CI 1.000,1.002,P < 0.001).Extracorporeal circulation time(OR=1.026,95%CI 1.001-1.052,P0.042),ventilator-assisted time(OR=1.030,95%CI 1.010 / 1).051,P = 0.003)was an independent risk factor for postoperative low cardiac output syndrome.Conclusion: These findings suggest that Lung infection,acute renal function injury,low-heart-displacement syndrome are the main complications that affect the recovery after heart valve replacement;the pre-operative combined COPD is an independent risk factor for postoperative pulmonary infection;and the time of extracorporeal circulation,the time of operation,The auxiliary time of the ventilator increases the risk of pulmonary infection after the operation.The amount of red suspended was related to the occurrence of acute renal function after operation.The time of cardiopulmonary bypass and the extension of the auxiliary time of the ventilator are related to the occurrence of low-heart-displacement syndrome after operation.
