Rocuronium and Fentanyl for Neonatal Intubation: A Randomized Clinical Trial (NEORIN) (NEORIN)

10 de junio de 2026 actualizado por: Jefferson Pereira Guilherme, UEA - Universidade Do Estado Do Amazonas

Effect of the Association of Fentanyl and Rocuronium on First-Attempt Success Rate of Tracheal Intubation in Newborns: A Randomized Clinical Trial

Tracheal intubation is a common and critical procedure in neonatal intensive care units (NICU). Despite its clinical importance, first-attempt success rates remain low (approximately 50%), and adverse events - including oxygen desaturation, bradycardia, and airway trauma - are frequent. Premedication with neuromuscular blocking agents has been associated with improved intubation conditions and fewer adverse events in neonates.

This randomized, double-blind, parallel-group clinical trial (NEORIN) aims to evaluate whether the addition of rocuronium (0,6 mg/kg IV) to standard fentanyl premedication (1 mcg/kg IV) improves first-attempt success rates of tracheal intubation in newborns admitted to the NICU of Maternidade Ana Braga, Manaus, Brazil. The control group will receive fentanyl plus saline placebo. Sugammadex (16 mg/kg IV) is available as a reversal agent in case of prolonged neuromuscular blockade.

A secondary aim is to assess neonatologists' and residents' knowledge of and barriers to the use of neuromuscular blocking agents in neonatal intubation.

Descripción general del estudio

Descripción detallada

Neonatal tracheal intubation is performed in approximately 15-20% of NICU admissions. First-attempt success rates are approximately 49%, and adverse tracheal intubation-associated events (TIAEs) occur in up to 18% of procedures, with severe oxygen desaturation in up to 48% (NEAR4NEOS registry, Foglia et al., 2019). Premedication with neuromuscular blocking agents has been independently associated with a 62% reduction in adverse events (aOR 0.38; 95% CI 0.25-0.57).

Rocuronium is a non-depolarizing neuromuscular blocking agent with rapid onset, stable hemodynamic profile, and full reversibility with sugammadex, making it a safe choice for neonatal premedication.

The NEORIN trial will enroll 102 newborns (51 per group) with postnatal age ≤28 days or corrected gestational age <44 weeks, requiring non-emergent tracheal intubation. Randomization will be performed in variable-sized permuted blocks (4 and 6), with allocation concealment through sequential opaque sealed envelopes.

Intervention group: fentanyl 1 mcg/kg IV + rocuronium 0.6 mg/kg IV. Control group: fentanyl 1 mcg/kg IV + saline placebo (equivalent volume). Sugammadex is available at the bedside throughout the study as a mandatory safety requirement.

The primary composite outcome is first-attempt intubation success without physiological instability, defined as correct tube placement on the first laryngoscopy attempt confirmed by colorimetric CO2 detection, with no SpO2 drop >20% from baseline and no bradycardia (HR <100 bpm). All procedures will be video-recorded for blinded outcome assessment.

A secondary descriptive study will assess neonatologists' and residents' knowledge of and barriers to neuromuscular blocking agent use in neonatal intubation, using a structured questionnaire applied before the start of the clinical trial.
