Tracheal Intubation Practice and Safety Across International PICUs: A Report From National Emergency Airway Registry for Children.

OBJECTIVES

It is unknown if variation in tracheal intubation practice and outcomes exist across PICUs in different geographical regions. We hypothesized there would be differences in the process of care and adverse outcomes for tracheal intubation across PICUs in six different geographical regions (New Zealand, Japan, Singapore, Germany, India, and North America).

DESIGN

Prospective multicenter pediatric tracheal intubation database (National Emergency Airway Registry for Children) SETTING:: Six non-North American (International) and 36 North American PICUs.

EVENTS

All PICU tracheal intubation encounters from July 2014 to June 2017 MEASUREMENTS AND MAIN RESULTS:: Adverse tracheal intubation-associated events and desaturation occurrence (oxygen saturation < 80%) were evaluated. A total of 1,134 and 9,376 TIs from International and North American PICUs were reported, respectively: primary tracheal intubation 9,060, endotracheal tube change 1,450. The proportion of tracheal intubations for endotracheal tube change was greater in International PICUs (37% vs 11%; p < 0.001). Median age for International tracheal intubations was younger compared with North America (0 yr [interquartile range, 0-2 yr] vs 1 yr (0-7 yr); p < 0.001). Among primary tracheal intubations, the most common indication was respiratory (International 67%, North American 63%; p = 0.049). Direct laryngoscopy was the most common device in both International (86%) and North American (74%) tracheal intubations. Occurrence of any adverse tracheal intubation-associated event was New Zealand 8%, Japan 17%, Singapore 9%, Germany 17%, and India 6%; International 11% versus North American 14%; p value equals to 0.003. Desaturation was reported less commonly in International PICUs: 13% versus North American 17%; p equals to 0.001. International PICUs used cuffed endotracheal tube less often (52% vs 95%; p < 0.001). Proportion of cuffed endotracheal tube use per PICU was inversely correlated with the rate of tube change (r = -0.67; p < 0.001).

CONCLUSIONS

There were both similarities and differences in tracheal intubation practice and outcomes across international PICUs. Fewer adverse tracheal intubation-associated events were reported from International versus North American PICUs. International PICUs used cuffed endotracheal tube less often and had higher proportion of endotracheal tube change.
