Application of Video Laryngoscopy for Minimally Invasive Surfactant Therapy: A Retrospective Comparative Cohort Study.

Minimally invasive surfactant therapy (MIST) has emerged as a preferred method of surfactant delivery. Pioneers of this technique have described the use of direct laryngoscopy (DL) for MIST. With the increasing application of video laryngoscopy (VL) for neonatal airway management, it is speculated that MIST techniques can be adapted for use with VL.

objectiveTo compare procedural success, operator ease of use, and complication of MIST using VL vs. MIST using DL.

methodsThis was a retrospective, observational cohort study conducted at a tertiary-level neonatal intensive care unit after obtaining ethical approval. We included neonates who received MIST between 1 October 2020 and 31 October 2022. Baseline demographic characteristics, along with procedural data, were collected. Primary outcome measures included the overall procedural success rate, the need for multiple attempts, and the total number of attempts. Secondary outcome measures included the occurrence of adverse events, the need for a second dose of surfactant, and the need for intubation within 7 days of the procedure. Means and SDs, independent

resultsOf the 79 neonates included, 37 neonates received MIST via VL, while 42 received MIST via DL. The median gestational age was lower in the VL group at 29.0 weeks vs. 30.5 weeks (

conclusionOverall, in our cohort, despite VL being a more recently adapted technology used more in smaller, sicker, and more premature neonates, procedural success, complications, and operator ease of use for MIST using VL and DL were comparable. Our findings show the successful application of VL for MIST and suggest procedural advantages that might facilitate universal adoption.
