Adrenal Insufficiency in Hemodynamically Unstable Neonatesafter Open-Heart Surgery

Abstract: The low dose (1 µg) ACTH stimulation test is a valid test to assess adrenal responsiveness among neonates after open heart surgery requiring CPB. Traditionally used basal serum cortisol level cutoff of <20 µg/dL used to define relative adrenal insufficiency may not be applicable in neonates undergoing open heart surgery on CPB thus indicating the need for re-defining adrenal insufficiency in this patient population.

“…Depending on definition, AI may occur in up to 45.7% of infants after cardiac surgery (13); 33% of subjects in our trial developed AI after CPB. Low serum total or free cortisol, inadequate response to adrenocorticotropic hormone (ACTH) stimulation test, high ACTH/cortisol ratio, and improvement in hemodynamics after corticosteroid administration have all been proposed for AI diagnosis in other studies, with inconsistent incidence and correlation with outcomes (4,5,14). Of these definitions, we found only post-CPB ACTH stimulation testing (1 mcg) was associated with clinical outcomes in the immediate postoperative period.…”

“…SIRS may disrupt the hypothalamic–pituitary–adrenal (HPA) axis leading to relative adrenal insufficiency (AI) after neonatal CPB . Emerging evidence supports the association of AI with morbidity after cardiac surgery , and that prophylactic postoperative steroid supplementation may improve hemodynamic outcomes via modulation of post‐CPB SIRS, prevention of AI, and/or supplementation of endogenous cortisol levels. However, AI lacks a clear definition and controversy still surrounds the utility of steroid administration in the critically ill neonate .…”

“…The patients that had a significant serum cortisol increase after ACTH test (>50 mg/dL) also had a higher mean arterial blood pressure at 48 h postoperatively. All patients included in the study had dexamethasone 0.5 mg/kg midnight before surgery and at induction [ 54 ]. In 38 neonates undergoing complex heart surgery, Mackie et al measured serum cortisol at 3 time-points: preoperatively, at 24 and 48 h postoperatively.…”
