Feasibility study of early blood pressure management in extremely preterm infants.

ABSTRACT: OBJECTIVE:To assess the feasibility of a randomized placebo controlled trial (RCT) of blood pressure (BP) management for extremely preterm infants. STUDY DESIGN:This was a prospective pilot RCT of infants 23-0/7 to 26-6/7 weeks gestation who had protocol-defined low BP in the first 24 postnatal hours. Enrolled infants were administered a study infusion (dopamine or placebo) and a study syringe medication (hydrocortisone or placebo). RESULTS:Of the 366 infants screened, 119 (33%) had low BP, 58 (16%) met all entry criteria, and 10 (3%) were enrolled. A total of 161 infants (44%) were ineligible because they received early indomethacin. Only 17% of eligible infants were enrolled. Problems with consent included insufficient time, parent unavailability, and physician unwillingness to enroll critically ill infants. Two infants were withdrawn from the study because of the potential risk of intestinal perforation with simultaneous administration of hydrocortisone and indomethacin. CONCLUSIONS:This pilot RCT was not feasible because of low eligibility and consent rates. An RCT of BP management for extremely preterm infants may require a waiver of consent for research in emergency care. The frequent use of early indomethacin and the associated risk of intestinal perforation when used with hydrocortisone may limit future investigations to only inotropic medications.

Project description:BACKGROUND:There are limited data to inform the choice between early treatment with continuous positive airway pressure (CPAP) and early surfactant treatment as the initial support for extremely-low-birth-weight infants. METHODS:We performed a randomized, multicenter trial, with a 2-by-2 factorial design, involving infants who were born between 24 weeks 0 days and 27 weeks 6 days of gestation. Infants were randomly assigned to intubation and surfactant treatment (within 1 hour after birth) or to CPAP treatment initiated in the delivery room, with subsequent use of a protocol-driven limited ventilation strategy. Infants were also randomly assigned to one of two target ranges of oxygen saturation. The primary outcome was death or bronchopulmonary dysplasia as defined by the requirement for supplemental oxygen at 36 weeks (with an attempt at withdrawal of supplemental oxygen in neonates who were receiving less than 30% oxygen). RESULTS:A total of 1316 infants were enrolled in the study. The rates of the primary outcome did not differ significantly between the CPAP group and the surfactant group (47.8% and 51.0%, respectively; relative risk with CPAP, 0.95; 95% confidence interval [CI], 0.85 to 1.05) after adjustment for gestational age, center, and familial clustering. The results were similar when bronchopulmonary dysplasia was defined according to the need for any supplemental oxygen at 36 weeks (rates of primary outcome, 48.7% and 54.1%, respectively; relative risk with CPAP, 0.91; 95% CI, 0.83 to 1.01). Infants who received CPAP treatment, as compared with infants who received surfactant treatment, less frequently required intubation or postnatal corticosteroids for bronchopulmonary dysplasia (P<0.001), required fewer days of mechanical ventilation (P=0.03), and were more likely to be alive and free from the need for mechanical ventilation by day 7 (P=0.01). The rates of other adverse neonatal outcomes did not differ significantly between the two groups. CONCLUSIONS:The results of this study support consideration of CPAP as an alternative to intubation and surfactant in preterm infants. (ClinicalTrials.gov number, NCT00233324.)

Project description:BackgroundDue to insufficient evidence, extremely preterm infants (≤28 wk of gestation) rarely receive early progressive feeding (small increments of feeding volumes between 1 and 4 d after birth). We hypothesized that early progressive feeding increases the number of full enteral feeding days in the first month after birth.ObjectiveThe aim of this study was to determine the feasibility and efficacy of early progressive feeding in extremely preterm infants.DesignIn this single-center randomized trial, extremely preterm infants born between September 2016 and June 2017 were randomly assigned to receive either early progressive feeding without trophic feeding (early feeding group) or delayed progressive feeding after a 4-d course of trophic feeding (delayed feeding group). Treatment allocation occurred before or on feeding day 1. The primary outcome was the number of full enteral feeding days in the first month after birth. Secondary outcomes were death, necrotizing enterocolitis (NEC), culture-proven sepsis, growth percentiles at 36 wk postmenstrual age, use of parenteral nutrition, and need for central venous access.ResultsSixty infants were included (median gestational age: 26 wk; mean ± SD birth weight: 832 ± 253 g). The primary outcome differed between groups (median difference favoring the early feeding group: +2 d; 95% CI: 0, 3 d; P = 0.02). Early progressive feeding reduced the use of parenteral nutrition (4 compared with 8 d; P ≤ 0.01) and the need for central venous access (9 compared with 13 d; P ≤ 0.01). The outcome of culture-proven sepsis (10% compared with 27%; P = 0.18), restricted growth (weight, length, and head circumference <10th percentile) at 36 wk postmenstrual age (25% compared with 50%; P = 0.07), and the composite outcome of NEC or death (27% compared with 20%; P = 0.74) did not differ between groups.ConclusionEarly progressive feeding increases the number of full enteral feeding days in extremely preterm infants. This trial was registered at www.clinicaltrials.gov as NCT02915549.
