Predicting the outcomes of intensive care for congenital malformations (CM) in newborns is one of the most serious problems in neonatology.
OBJECTIVE
To identify predictors of intensive care outcomes in CM children requiring surgery in early neonatal period according to endocrine status.
MATERIAL AND METHODS
There were 34 newborns with CM and gestation period 39.23 (38—40) weeks. Diaphragmatic hernia (25%), esophageal atresia with tracheoesophageal fistula (20%), Ledd syndrome (10%) and omphalocele (15%) were the most common. Mean age of children was 2.5 (1—4) days.
RESULTS
A new prediction model for ventilation time includes serum cortisone and cholecalciferol after surgery, concentration of dehydroepiandrosterone a day after surgery and SpO2 immediately after surgery. Sensitivity was 0.832, specificity — 0.956, AUC — 0.958. To assess the probability of long-term ICU-stay (> 5 days) in patients with favorable outcomes, appropriate model involves concentration of 17-OH pregnenolone immediately after surgery, gradients of 17-OH pregnenolone and progesterone, as well as the ratio of 17-OH pregnenolone and aldosterone immediately after surgery and one day later (sensitivity — 0.842; specificity — 0.9; AUC — 0.942). The only independent predictor of adverse outcomes in CM newborns is lactate concentration. Its concentration was significantly higher in deceased children immediately after surgery (5.6 vs 2.2 mmol/L; p< 0.05) and a day later (6.1 vs 1.8 mmol/L; p< 0.05). The probability of unfavorable outcome is significantly higher in case of the ratio of 17-hydroxypregnenolone/corticosterone and 17-hydroxypregnenolone/cortisone equal to zero on the first day after surgery.
CONCLUSION
Depletion of hormone precursors immediately after surgery and on the first day after surgery is a risk factor for unfavorable outcomes.
