Effect of Atropine With Propofol vs Atropine With Atracurium and Sufentanil on Oxygen Desaturation in Neonates Requiring Nonemergency Intubation: A Randomized Clinical Trial.

Importance: Propofol or a combination of a synthetic opioid and muscle relaxant are both recommended for premedication before neonatal intubation but have yet to be compared. Objective: To compare prolonged desaturation during neonatal nasotracheal intubation after premedication with atropine-propofol vs atropine-atracurium-sufentanil treatment. Design, Setting, and Participants: Multicenter, double-blind, randomized clinical trial (2012-2016) in 6 NICUs in France that included 173 neonates requiring nonemergency intubation. The study was interrupted due to expired study kits and lack of funding. Interventions: Eighty-nine participants were randomly assigned to the atropine-propofol group and 82 to the atropine-atracurium-sufentanil group before nasotracheal intubation. Main Outcomes and Measures: The primary outcome was prolonged desaturation (Spo2 <80% lasting > 60 seconds), using intention-to-treat analysis using mixed models. Secondary outcomes assessed the characteristics of the procedure and its tolerance. Results: Of 173 neonates randomized (mean gestational age, 30.6 weeks; mean birth weight, 1502 g; 71 girls), 171 (99%) completed the trial. Of 89 infants, 53 (59.6%) in the atropine-propofol group vs 54 of 82 (65.9%) in the atropine-atracurium-sufentanil group achieved the primary outcome (adjusted RD, -6.4; 95% CI, -21.0 to 8.1; P = .38). The atropine-propofol group had a longer mean procedure duration than did the atropine-atracurium-sufentanil group (adjusted RD, 1.7 minutes; 95% CI, 0.1-3.3 minutes; P = .04); a less frequent excellent quality of sedation rate, 51.7% (45 of 87) vs 92.6% (75 of 81; P < .001); a shorter median time to respiratory recovery, 14 minutes (IQR, 8-34 minutes) vs 33 minutes (IQR, 15-56 minutes; P = .002), and shorter median time to limb movement recovery, 18 minutes (IQR, 10-43 minutes) vs 36 minutes (IQR, 19-65 minutes; P = .003). In the 60 minutes after inclusion, Spo2 was preserved significantly better in the atropine-propofol group (time × treatment interaction P  = .02). Of the atropine-propofol group 20.6% had head ultrasound scans that showed worsening intracranial hemorrhaging (any or increased intraventricular hemorrhage) in the 7 days after randomization vs 17.6% in the atropine-atracurium-sufentanil group (adjusted RD, 1.2; 95% CI, -13.1 to 15.5, P = .87). Severe adverse events occurred in 11% of the atropine-propofol group and in 20% of the atropine-atracurium-sufentanil group. Conclusions and Relevance: Among neonates undergoing nonemergency nasotracheal intubation, the frequency of prolonged desaturation did not differ significantly between atropine used with propofol or atropine used with atracurium and sufentanil. However, the study may have been underpowered to detect a clinically important difference, and further research may be warranted.
