Abstract: Objective To identify the risk factors for shortterm adverse events in infants with congenital heart diseases receiving open heart surgical correction with cardiopulmonary bypass (CPB), in order to improve the outcome by adopting appropriate treatment measures. Methods We retrospectively analyzed the clinical data of 98 consecutive children with congenital heart diseases who underwent surgical correction with CPB in Beijing Fu Wai Hospital from November 2009 to December 2009. The patients were divided into two groups according to the postoperative complications. Among the patients without complications(n=40): there were 24 males and 16 females with an age of 7.60±0.40 months and a weight of 7.80±0.30 kg. In the patients with complications (n=58): there were 42 males and 16 females with an age of 6.20±0.40 months and a weight of 6.70±0.20 kg. In both groups, perioperative data were recorded, including preoperative fast blood glucose, creatinine, time of aortic crossclamp, modified or zerobalanced ultrafiltration, postoperative glucose level, concentration of lactate, notrope score and complications. Risk stratification was performed by Risk Adjusted Classification for Congenital Heart Surgery (RACHS-1). Univariate analysis and logistic regression analysis were used to identify the risk factors for shortterm adverse events. Results One patient(1.02%) died of circulatory failure during the perioperative period. Thirtyseven patients [CM(159mm]were supported by at least 2 vasoactive drugs for more than 48hours,29 by mechanical ventilation for more than 24 hours, 5 needed reintubation, 1 experienced tracheotomy, 31 suffered from noscomial infection, 4 had wound infection, 3 developed renal failure, and 1 developed hepatic dysfunction. By logistic regression analysis, age (OR=0.750, P=0.012), percutaneous oxygen saturation (OR=0.840,P=0.005), aortic crossclamp time (OR=1.040, P=0.008), postoperative glucose level (patients with a mean glucose level lower or equal to 8.33 mmol/L had a probability of developing adverse outcomes five times higher; OR=5.051, P=0.011) were found to be the risk factors for shortterm adverse outcomes. Conclusion Age, percutaneous oxygen saturation and aortic crossclamp time are associated with the shortterm adverse outcome of infants undergoing congenital heart disease correction with CPB. The present results do not support perioperative hyperglycemia as a risk factor for adverse outcome.
