Abstract:
Objective To study the risk factors of prolonged postoperative recovery after the total cavopulmonary connection(TCPC) in the current era.Methods Data on all patients admitted to the cardiac intensive care unit (CICU) after a TCPC between January 2013 and March 2014 were retrospectively analyzed.We excluded all patients who died and required TCPC takedown.The study cohort was further divided into a prolonged recovery group that included patients with 75％ ile for duration of mechanical ventilation or pleural drainage,and a standard recovery group which included all other patients.A multivariable logistic regression model was used to compare demographic,anatomic,and physiological variables between the prolonged and standard recovery groups.Then,the cohort was separated into a high volume resuscitation group and a low volume resuscitation based on the 75％ ile for volume resuscitation(ml/kg) administered on the first three days after the TCPC.Results Totally 118 TCPC operations were performed.Of the study population (n =118),the median age was 3.8 years (3.1 to 4.8 years) and median weight was 14.8 kg(13.3 to 17.1 kg).The most common diagnosis was double outlet of right ventricle (n =47,39.8％).The extracardiac conduit fenestrated TCPC was the most common surgery(n =79,66.9％).Within the study population,43 (39.8％) patients met criteria for prolonged recovery.Univariate risk factors for prolonged recovery included higher preoperative mPAP(P =0.022),atrioventricular valve regurgitation (P =0.000),longer total bypass time (P =0.044),higher postoperative central venous pressure (P =0.000),AST (P =0.001),ALT (P =0.010),NT-proBNP (P =0.000),SaO2 (P =0.012),I n-otropic score (P =0.001),higher incidence of arrhythmia (P =0.000),low cardiac output syndrome (P =0.000),need for peritoneal dialysis (P =0.000),and requirement for greater volume resuscitation during the 72 postoperative hours(75％ for the entire group,P =0.000).In a multivariable Logistic model,need for greater volume resuscitation (OR 10.860,95 ％ CI 2.681,43.987) and the higher postoperative central venous pressure (OR 1.446,95 ％ C I 1.113,1.879) were the only two independent risk factors for prolonged outcome after the TCPC.Conclusion The need for high volume expansion and higher central venous pressure were the risk factors of mediate prolonged recovery.
