Abstract
Introduction: This study aimed to evaluate the treatment results, complications, and the factors affecting mortality in cases who were followed up postoperatively in the pediatric intensive care unit (PICU) after the Glenn shunt procedure.
Materials and Methods: The duration of the patients on the pump during surgery, transition times to feeding, blood gas and other laboratory parameters, complications developed during follow-up in the intensive care unit, and exitus rates were evaluated retrospectively.
Results: BDG was performed due to tricuspid atresia, the most common diagnosis (30.2%). In the evaluation of the relationship between postoperative patient findings and exitus, a positive correlation was found between the duration of inotropic support, early extubation, and the duration of HFNC therapy in all patients (p<0.05); and a negative correlation was found in terms of the fluid the patients received on the first day after surgery (p<0.05). In patients who developed complications, a negative correlation was observed only in terms of the fluid they received on the first day after surgery (p<0.05)
Conclusions: In terms of all patients, it was observed that mortality increased with early extubation and prolonged duration of inotropic support and HFNC therapy, and it decreased as the fluid the patients received on the first day after surgery decreased. In patients who developed complications, it was only observed that mortality decreased as the fluid the patients received on the first day after surgery decreased.
