Analysis Of The Associated Risk Factors For Lung Infection After The Surgery Under The Cardio-Pulmonary Bypass

Objectives:To retrospectively explore the associated risk factors for lung infection after the surgery under the Cardio-pulmonary Bypass.Methods:From January 2016 to December 2017,a total of 770 congenital heart disease(CHD)who were confirmed and underwent the surgery under the Cardio-pulmonary Bypass,there were 405 males and 365 females included in the study and the mean follow-up period was 32.63±33.05 months.Univariate comparisons and binary logistic regression analysis were applied to explore risk factors,including gender,weight,the classification of CHD,age of surgery,preoperative hospital stay,operation time,anesthesia time,the time of the Cardio-pulmonary Bypass,aortic occlusion time,number of intubation,ventilator assisted ventilation time,preoperative serum total protein level,preoperative serum albumin level,pulmonary hypertension severity.Results:There were 34.68(267/770)patients fell lung infection after the surgery.Weight,the classification of CHD,age of surgery,preoperativehospital stay,operation time,anesthesia time,the time of the Cardio-pulmonary Bypass,aortic occlusion time,number of intubation,ventilator assisted ventilation time,pulmonary hypertension severity were susceptible to deformity relapse.Moreover,the binary logistic analysis also showed that the weight,ventilator assisted ventilation time,preoperative hospital stay,the time of the Cardio-pulmonary Bypass,were independent risk factors of recurrence.Conclusion: Appropriate nutritional supported,shortened the time of the Cardio-pulmonary Bypass and early extraction of tracheal intubation are effective ways to reduce pulmonary infection after surgery under the Cardio-pulmonary Bypass for children with congenital heart disease.
