ABSTRACT
@#Objective To summarize the early clinical features and perioperative management strategies for patients with transposition of the great arteries (TGA) after one-stage arterial switch operation (ASO), and investigate the risk factors for prolonged recovery in ICU, with a focus on the age structure and deformity complexity. Methods The clinical data of 231 consecutive TGA patients who underwent one-stage ASO were retrospectively analyzed. There were 165 males and 66 females, aged from 3 d to 10 years. The patients were sequenced by the length of ICU stay. The time at the 75th percentile was defined as the critical value for grouping. Patients with an ICU stay time over this point were allocated to a prolonged recovery group (n=54), while the rest were allocated to a normal recovery group (n=177). The perioperative clinical data were compared between the two groups, and the risk factors for prolonged recovery were evaluated. Results About half (49.6%) of the patients received late operation. The mean ICU stay time was 23.9±15.6 d in the prolonged recovery group, and 4.9±2.3 d in the normal recovery group. Complication of aortic arch lesion, delayed chest closure and postoperative pulmonary infection were independent risk factors for prolonged recovery after ASO in ICU. However, late operation had no significant effect on the overall recovery. Conclusion With strict surgery indications and excellent postoperative management, most patients can have satisfactory early-stage outcomes, but are confronted with increased complications, which is associated with prolonged recovery. Complication of aortic arch lesion, delayed chest closure and postoperative pulmonary infection are independent factors for delayed recovery of ASO.
ABSTRACT
Objective: To explore the relationship between thyroid hormone levels and prolonged recovery after cardiac surgery with cardiopulmonary bypass (CPB) in congenital heart disease (CHD) children younger than 1 year of age. Methods: A total of 186 CHD children younger than 1 year treated in our hospital from 2014-01 to 2015-01 were retrospectively summarized. According to the pediatric intensive care unit (PICU) stay time, the patients were divided into 2 groups: Prolonged recovery group, the patients stated in PICU≥5 days,n=39 and Non-prolonged recovery group, the patients stayed in PICU0.05. Multivariable logistical regression analysis presented that low level of FT3 within 24 hours of operation was the independent risk factor for prolonged recovery (OR= 0.32, 95% CI 0.12-0.84,P=0.02); linear regression analysis indicated that post-operative reduction of thyroid hormone was related to low body weight of the patients (r=0.11,P<0.001). Conclusion: Lower body weight was usually having lower level of FT3 within 24 hours of operation, which was the independent predictor for prolonged recovery in CHD children younger than 1 year after cardiac surgery.
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.
