ABSTRACT

@#Objective    To analyze the effect of modified Blalock-Taussig shunt on the treatment of cyanotic congenital heart diseases in neonates. Methods    The clinical data of 33 neonates undergoing modified Blalock-Taussig shunt between January 1, 2013 and December 31, 2017 were reviewed, including 28 males and 5 females with the age of 3.0-28.0 (18.0±6.1) d and weight of 1.9-3.7 (2.9±0.5) kg. Results    There were 3 (9.1%) in-hospital deaths. Ten (30.3%) patients required early unplanned reoperations after surgery. Five (15.2%) patients were lost to follow-up. In the multivariate analysis, preoperative acidosis, emergency operation and postoperative bedside thoracotomy were independent risk factors of early death. During the follow-up of 18.0-93.0 (40.2±22.5) months, there was no death and 9 (36.0%) survival patients underwent corrective surgery and stage-two palliative surgery. In the multivariate analysis, preoperative hyperhemoglobinemia was an independent risk factor of nonadministration of the corrective surgery and stage-two palliative surgery. Receiver operating characteristic curve showed that preoperative hyperhemoglobinemia was significant in determining whether secondary surgery was possible. Conclusion    The modified Blalock-Taussig shunt is effective in promoting development of pulmonary arteries and preparing for the secondary surgery. The rate of mortality and postoperative complications after the neonatal modified Blalock-Taussig shunt remains high. The rate of secondary surgery is still low during follow-up.

ABSTRACT

Objective: The aim was to compare various pre-and post-operative parameters and to identify the predictors of mortality in neonates, infants, and older children undergoing Modifi ed Blalock Taussig shunt (MBTS). Materials and Methods: Medical records of 134 children who underwent MBTS over a period of 2 years through thoracotomy were reviewed. Children were divided into three groups-neonates, infants, and older children. For analysis, various pre-and post-operative variables were recorded, including complications and mortality. Results: The increase in PaO2 and SaO2 levels after surgery was similar and statistically signifi cant in all the three groups. The requirement of adrenaline, duration of ventilation and mortality was signifi cantly higher in neonates. The overall mortality and infant mortality was 4.5% and 8%, respectively. Conclusion: Neonates are at increased risk of complications and mortality compared with older children. Age (<30 days), weight (<3 kg), packed red blood cells transfusion >6 ml/kg, mechanical ventilation >24 h and post shunt increase in PaO2 (PDiff) <25% of baseline PaO2 are independent predictors of mortality in children undergoing MBTS.
