Development of a novel reference nomogram for endotracheal intubation in neonatal emergency transport setting.

AIM: Neonatal endotracheal intubation is a challenging procedure during transport. The aim of this study was to evaluate the effectiveness of the emergency intubation guidelines followed by our Neonatal Emergency Transport Service (NETS).
METHODS: Our transport intubation guidelines follows a weight-based nomogram for nasal intubation, and the tube position is clinically verified after intubation, while the postintubation chest X-ray is postponed to Neonatal Intensive Care Unit (NICU) admission. Data on postnatal age, weight and tube insertion depth were obtained from the online NETS clinical database, and the postintubation chest X-ray images were assessed.
RESULTS: During the study period, 161 newborn infants were nasally intubated during transport, and received a postintubation radiograph at NICU admission. A total of 130 neonates (80.7%) had the endotracheal tube (ETT) correctly positioned between T1 and T2 vertebrae, while 12 (7.5%) was at C7 vertebrae level and 19 (11.8%) at T3. No patients had ETT tip positioned at T4 vertebrae level or below. No adverse events related to intubation were observed.
CONCLUSION: Our intubation procedure showed a good reliability and safety in neonatal critical care transport, although chest X-ray to confirm the tube placement is postponed to NICU arrival. Based on our results, we suggest a revised version of weight-based nomogram for nasal intubation. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.
