Pharmacologic Adjuncts for Neonatal Tracheal Intubation: The Evidence Behind Premedication

Premedication such as analgesia, sedation, vagolytics, and paralytics may improve neonatal tracheal intubation success, reduce intubation-associated adverse events, and create optimal conditions for performing this high-risk and challenging procedure. Although rapid sequence induction including a paralytic agent has been adopted for intubations in pediatric and adult critical care, neonatal clinical practice varies. This review aims to summarize details of common classes of neonatal intubation premedication including indications for use, medication route, dosage, potential adverse effects in term and preterm infants, and reversal agents. In addition, this review shares the literature on national and international practice variations; explores evidence in support of establishing premedication guidelines; and discusses unique circumstances in which premedication use has not been established, such as during catheter-based or minimally invasive surfactant delivery. With increasing survival of extremely preterm infants, clear guidance for premedication use in this population will be necessary, particularly considering potential short- and long-term side effects of procedural sedation on the developing brain.
