Objective To compare early routine pharmacologic treatment of moderate-to-large patent ductus arteriosus (PDA) at the end of week 1 with a conservative approach that requires prespecified respiratory and hemodynamic criteria before treatment can be given. Study design A total of 202 neonates of <28 weeks of gestation age (mean, 25.8 ± 1.1 weeks) with moderate-to-large PDA shunts were enrolled between age 6 and 14 days (mean, 8.1 ± 2.2 days) into an exploratory randomized controlled trial. Results At enrollment, 49% of the patients were intubated and 48% required nasal ventilation or continuous positive airway pressure. There were no differences between the groups in either our primary outcome of ligation or presence of a PDA at discharge (early routine treatment [ERT], 32%; conservative treatment [CT], 39%) or any of our prespecified secondary outcomes of necrotizing enterocolitis (ERT, 16%; CT, 19%), bronchopulmonary dysplasia (BPD) (ERT, 49%; CT, 53%), BPD/death (ERT, 58%; CT, 57%), death (ERT,19%; CT, 10%), and weekly need for respiratory support. Fewer infants in the ERT group met the rescue criteria (ERT, 31%; CT, 62%). In secondary exploratory analyses, infants receiving ERT had significantly less need for inotropic support (ERT, 13%; CT, 25%). However, among infants who were ≥26 weeks gestational age, those receiving ERT took significantly longer to achieve enteral feeding of 120 mL/kg/day (median: ERT, 14 days [range, 4.5-19 days]; CT, 6 days [range, 3-14 days]), and had significantly higher incidences of late-onset non-coagulase-negative Staphylococcus bacteremia (ERT, 24%; CT,6%) and death (ERT, 16%; CT, 2%). Conclusions In preterm infants age <28 weeks with moderate-to-large PDAs who were receiving respiratory support after the first week, ERT did not reduce PDA ligations or the presence of a PDA at discharge and did not improve any of the prespecified secondary outcomes, but delayed full feeding and was associated with higher rates of late-onset sepsis and death in infants born at ≥26 weeks of gestation. Trial registration ClinicalTrials.gov: NCT01958320.

Resuscitation with room air failed to achieve our target oxygen saturation by 3 minutes of life, and we recommend that it not be used for preterm neonates.

Airway obstruction occurs in the majority of the very low birth weight infants who receive ventilation with a face mask during resuscitation and the use of a colorimetric detector can facilitate its recognition and management.

OBJECTIVE. The purpose of this work was to investigate whether using a muscle relaxant would improve intubation conditions in infants, thereby decreasing the incidence and duration of hypoxia and time and number of attempts needed to successfully complete the intubation procedure. PATIENTS/METHODS. This was a prospective, randomized, controlled, 2-center trial. Infants requiring nonemergent intubation were randomly assigned to receive atropine and fentanyl or atropine, fentanyl, and mivacurium before intubation. Incidence and duration of hypoxia were determined at oxygen saturation thresholds of ≤85%, ≤75%, ≤60%, and ≤40%. Videotape was reviewed to determine the time and number of intubation attempts and duration of action of mivacurium. RESULTS. Analysis of 41 infants showed that incidence of oxygen saturation ≤60% of any duration was significantly less in the mivacurium group (55% vs 24%). The incidence of saturation level of any duration ≤85%, 75%, and 40%; cumulative time ≥30 seconds; and time below the thresholds were not significantly different. Total procedure time (472 vs 144 seconds) and total laryngoscope time (148 vs 61 seconds) were shorter in the mivacurium group. Successful intubation was achieved in ≤2 attempts significantly more often in the mivacurium group (35% vs 71%). CONCLUSIONS. Premedication with atropine, fentanyl, and mivacurium compared with atropine and fentanyl without a muscle relaxant decreases the time and number of attempts needed to successfully intubate while significantly reducing the incidence of severe desaturation. Premedication including a short-acting muscle relaxant should be considered for all nonemergent intubations in the NICU.
