845: TRANSITION FROM DIRECT TO VIDEO LARYNGOSCOPY IN A PEDIATRIC ICU

Abstract

Introduction: As an infection control measure for COVID-19, our PICU transitioned to near universal video laryngoscopy (VL). In 2019, 24% of intubations used VL; this increased to 96% in 2021. Comparing these two cohorts elucidates the effect of transitioning from direct laryngoscopy (DL) to VL on first time success rate (FTSR), Cormack-Lehane (C-L) grade view and successful trainee intubation. First time intubation success is associated with fewer complications and is therefore an important marker of intubation safety. Methods: Single Center retrospective case control. Data for 2019 were identified via chart review. Data from 2021 were obtained through a dedicated form introduced in the Fall of 2020. Each comparison group was limited to a full calendar year (Jan-Dec) to account for progression in trainee skill. A comparison was made between all patients in cohort groups with additional stratification of patients above and below the age of one. Included intubations were those in the PICU as well as those in the pediatric floor or ED performed by PICU staff. Statistics via Fischer Exact test. Results: 75 patients met criteria for 2019 and 73 in 2021. The age range in both groups was 2 days to 23 years. C-L view was documented in 72 of 75 patients in 2019 and all patients in 2021. 2019 had a 69.4% grade 1 C-L view rate, while 2021 had a 79.5% grade 1 C-L view rate (p=0.19). The overall FTSR in 2019 was 57.3% vs 65.7% in 2021 (p=0.31). 26 children under the age of one were intubated in both years, with a FTSR of 53.8% and 50% respectively. The FTSR in children above one year was 59.2% and 74.5% respectively (p=0.13). Additionally, an airway provider was documented in all but two cases in 2019. Of these, 75.3% were managed successfully by pediatric subspecialty fellows (PICU or rotating PEM). In 2021 this number increased to 84.9% (p=0.21). Conclusions: FTSR did not improve with transition to VL. In the 2021 cohort, children above age one had a 15.3% increased FTSR and trainees had a 9.6% increase in completed intubations. While not significant, these findings would benefit from reanalysis with a larger sample. First time success is an important marker for safe intubation practice, however there may be other benefits to either approach such as set up time and assistance from a second viewer.
