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.
