The purpose of this study is to conduct a double blinded randomized control trial to determine the safety and efficacy of using IV fentanyl and atropine prior to Less Invasive Surfactant Administration (LISA) procedure in preterm infants with Respiratory Distress Syndrome compared to the local standard of care to perform this procedure without any premedication.

Hypothesis: In infants greater than or equal to 29 weeks gestational age requiring the Less Invasive Surfactant Administration procedure, premedication with a combination of IV atropine and IV fentanyl will be associated with fewer combined bradycardia events, defined as heartrate less than 100 beats per minute for longer than 10 seconds, and hypoxemia events, defined as saturations less than or equal to 80% for longer than 30 seconds, during the procedure compared with placebo.

Specific Aims:

  • To determine if infants receiving IV fentanyl and atropine prior to LISA will have a decrease in hypoxemia and bradycardia events during the procedure compared to infants receiving placebo
  • To determine if infants receiving premedication prior to Less Invasive Surfactant Administration will have higher procedure first attempt success rate compared with infants receiving placebo
  • To determine the effect of premedication on cerebral oxygenation compared to placebo during and for 12 hours after Less Invasive Surfactant Administration using cerebral Near Infrared Spectroscopy
  • To determine the effect of premedication prior to Less Invasive Surfactant Administration on the need for mechanical ventilation for 24 hours after the procedure
