Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Till date, no studies are available that have evaluated the incidence of relative adrenal insufficiency in preterm very low birth weight (VLBW) infants with shock. The focus had been on stable preterm and critically ill preterm infants. Given that steroid treatment improves blood pressure and stabilizes cardiovascular status in preterm infants with volume and pressor-resistant hypotension,it becomes essential to examine the incidence of adrenal insufficiency in this cohort (rather than a broad group of critically ill preterm infants). Moreover, there are no studies on adrenal function in Indian neonates.

The purpose of this study is to compare the levels of basal and stimulated (using low dose \[1µg/k\] ACTH) cortisol levels in preterm (28-34 weeks gestation) very low birth weight (birth weight 750 gm to 1500 gm) infants with shock in the first week of life requiring vasopressor therapy and matched (gestation, birth weight, postnatal age-matched) hemodynamically stable infants ('control group').

Shock

Preterm VLBW infants with shock (BP \<3rd centile for gestation and birth weight with at least one of the following:

1. Prolonged capillary refill time (\>3sec)
2. Reduced urine output (\<1 mL/kg/hr)
3. Metabolic acidosis (Base deficit \>5)

No interventions assigned to this group

No shock

Hemodynamically stable infant with normal blood pressure, capillary refill time, and urine output
