Background Endotracheal intubation of very low birth weight infants (VLBWI) is an essential procedure in NICUs, but intubation experience is often limited. Video laryngoscopy (VL) has been described as a tool to improve intubation skills, but studies in high-risk neonatal populations are limited. Objective The aim of this study was to investigate whether VL is a useful tool to support airway management in high-risk premature infants with inexperienced operators. Methods In this crossover study predominantly inexperienced participants were exposed in random sequence to VL and conventional direct laryngoscopy (DL) for endotracheal intubation of a VLBWI simulation manikin to measure total time, number of attempts, success rate on first attempt, view of the vocal cords and perceived subjective safety until successful intubation. Results In our study group of 94 participants there was no significant difference in the total time (mean VL: 34 s (±24 s); DL: 37 s (±28 s), p = 0.246), while the number of intubation attempts using VL was significantly lower (mean VL: 1.22 (±0.53); DL: 1.37 (±0.60), p = 0.023). Success rate of VL during the first attempt was significantly higher (VL: 84%; DL 69%, p = 0.016), view of the vocal cords was significantly better and perceived subjective safety was increased using VL. Conclusions Our study results suggest that with rather inexperienced operators, VL can be a useful tool to increase rate of successful endotracheal intubation of VLBWI and to improve their perceived safety during the procedure, which may have an impact on mortality and/or morbidity.
