Abstract:
Objective:To explore the risk factors of early delayed recovery after right ventricular-extrapulmonary arterial(RV-PA)conduit reconstruction.Methods:From 2017 to 2021, the children with RV-PA conduit reconstruction, who were treated in our hospital were retrospectively analyzed.The demographic data and peri-operative clinical data of the patients were collected for statistical analysis.Results:Fifty-five patients were included in the study.The patients were sequenced by the length of ICU stay.The time at the 75th percentile was defined as the critical value for grouping.According to the ICU stay time of the children, they were divided into normal recovery group(ICU stay ≤7 days, n=40)and delayed recovery group(ICU stay>7 days, n=15).The mechanical ventilator time in the whole group was 24(0, 1 408)h, and the ICU stay time was 4(1, 67)d.Six cases required extracorporeal membrane oxygenation (ECMO) support, and two cases died.In the multivariate Logistic regression analysis of two groups, long cardiopulmonary bypass(CPB) time( OR=1.034, 95% CI 1.009-1.061, P=0.009)and poor right ventricular function( OR=9.536, 95% CI 1.010-90.037, P=0.049)were independent risk factors for early delayed recovery. Conclusion:The risk of RV-PA conduit reconstruction is high.The proportion of ECMO support is increased.The mortality rate is higher.Right heart dysfunction and prolonged CPB time are risk factors for delayed postoperative recovery.
