Comparative evaluation of the results of cardiosurgical treatment of infants born with low and normal body weigh

Despite advances in surgical technique, anesthesiology and intensive care, low birth weight remains to be a risk factor for adverse outcome in children after cardiac surgery.

The aim of the study is to compare perioperative parameters, postoperative complications and outcomes in low and normal birth weight infants undergoing cardiac surgery.

Materials and methods. A retrospective single-center study of the course of the perioperative period in children after operations on the open heart and vessels. 103 patients were selected for the study. The patients were divided into two groups: group 1 — infant with a body weight at the time of surgery less than 2.5 kg. and group 2 — infant with body weight from 2.5 to 3.5 kg. Preoperative clinical and demographic data, intraoperative parameters, postoperative complications and outcomes were assessed.

Results. Comparative analysis of perioperative parameters, postoperative complications and mortality did not show statistically significant differences between the two groups. Regressing analysis did not show a statistically significant effect of LBW on mortality. A significant risk of death was revealed during repeated unplanned surgical intervention and the duration of the child stay in the ICU.

Conclusion. LBW at birth in children with CHD did not lead to an increase in the incidence of postoperative complications and mortality.
