Hydrocortisone Treatment In Systemic Low Blood Pressure During Hypothermia in Asphyxiated Newborns

Summary

This is a prospective, randomized, double-blind, placebo controlled, single center study to compare low dose hydrocortisone vs placebo in systemic low blood pressure during hypothermia treatment in asphyxiated newborns. Patients will be allocated to one of the treatment arms (hydrocortisone or placebo) while receiving conventional inotropic therapy as needed. The hypothesis is that cooled asphyxiated neonates develop relative adrenal insufficiency that may contribute to hypotension and lower efficacy of inotropic therapy in this patient population. Thus, the investigators are planning to measure initial serum cortisol levels and investigate the cardiovascular effects of low dose hydrocortisone supplementation besides conventional inotropic therapy in a placebo-controlled fashion.
