Objective To investigate clinical features and risk factors of prolonged postoperative recovery of pediatric patients in ICU after total cavopulmonary connection（TCPC），provide evidence for risk stratification management strategy， and enhance their postoperative recovery. Methods We conducted a retrospective analysis of clinical data of 81 patients undergoing TCPC in Fu Wai Hospital from January 2010 to July 2012. Three patients who died postoperatively were excluded from analysis. Prolonged postoperative recovery was defined as patients whose postoperative mechanical ventilation time was longer than that of 75% of all the patients. A total of 78 patients were divided into normal recovery group and prolonged recovery group. There were 59 patients in the normal recovery group including 34 male and 25 female patients with their age of 62.5±20.7 months，and 19 patients in the prolonged recovery group including 11 male and 8 female patients with their age of 64.8±29.8 months. Perioperative variables were compared between the two groups. Results The average cardiopulmonary bypass time of all the 81 patients was 107.6±54.1 （33-350） minutes. The average aortic cross-clamping time of 17 patients was 46.4±31.5 （22-143） minutes. Three patients （3.7%） died postoperatively because of severe low cardiac output syndrome and thrombosis in the extracardiac conduit. The mechanical ventilation time and ICU stay were 7.5 hours and 1.6 days respectively in the normal recovery group，which were both significantly prolonged in the prolonged recovery group. Preoperative high hemoglobin level，coexistence of intracardiac anomalies，longer cardiopulmonary bypass time，and non-fenestrated procedure were the main risk factors of prolonged postoperative recovery. Conclusion Early extubation and fast track recovery can be achieved in most of TCPC patients. Risk stratification management strategies may contribute to successful postoperative recovery of critical patients after TCPC.
ObjectiveTo analyze risk factors contributing to prolonged postoperative recovery after Fontan operation. MethodsClinical data of 60 patients undergoing Fontan operation between January 2012 and June 2013 in Beijing Fu Wai Hospital were retrospectively analyzed, including their demographic data, preoperative angiography and echocardiogram, and preoperative, intraoperative and postoperative hemodynamic data and blood test results. According to different length of hospital stay (LOS), all the 60 patients were divided into 2 groups. In the normal recovery group, there were 45 patients including 33 males and 12 females with their age of 5.7±1.7 years, whose LOS was shorter than 32.5 days. In the prolonged recovery group, there were 15 patients including 10 males and 5 females with their age of 4.9±1.6 years, whose LOS was longer than 32.5 days (over 75th percentile of LOS). LOS of the 60 patients ranged from 12 to 53 days, and 75th percentile of LOS was 32.5 days. Clinical results were compared between the 2 groups, and risk factors for prolonged postoperative recovery were analyzed. ResultsPreoperatively, their oxygen saturation by pulse oximetry was 80.5%±7.4%, ejection fraction (EF)was 64.1%±6.6%, Nakata index was 370.6±234.2 mm2/m2, Mcgoon ratio was 2.2±0.7, and pulmonary arterial pressure (PAP)was 12.4±4.0 mm Hg. Twenty-seven patients (45.0%)received Glenn procedure before Fontan operation at the age of 0.9-4.0 years, and the duration from Glenn procedure to Fontan operation was 1.0-5.1 years. Two patients (3.3%)died after Fontan operation. Cardiopulmonary bypass time of 55 patients who received Fontan operation under parallel circulation was 112.0±52.4 minutes. Aortic cross-clamping time of 5 patients who received concomitant repair of intracardiac anomalies under circulatory arrest was 44.8±9.2 minutes. The duration of mechanical ventilation was 18.8±6.4 hours, and ICU stay was 5.1±2.1 days. Univariate analysis showed that risk factors for prolonged postoperative recovery included higher preoperative PAP (P < 0.05), lower preoperative EF (P < 0.05), right ventricle as functional single ventricle (P < 0.05), previous Glenn procedure history (P < 0.05), concomitant total anomalous venous connection (P < 0.05), higher postoperative lactate level (P < 0.05), higher postoperative central venous pressure (P < 0.05), the need for greater volume of fluid resuscitation during the first 24 hours postoperatively (P < 0.05), long duration of chest drainage (P < 0.05)and postoperative infection (P < 0.05). ConclusionShort-term clinical results of Fontan operation for the treatment of functional single ventricle are satisfactory. Careful assessment and appropriate management of risk factors are helpful to improve postoperative recovery after Fontan operation.
