Overview

Peri-intubation complications are important sequelae of airway management in the emergency department (ED). Our objective was to quantify the increased risk of complications with multiple attempts at emergency airway intubation in the ED. This is a secondary analysis of a prospectively collected multicenter registry (National Emergency Airway Registry) consisting of attempted ED intubations among subjects aged >14 years. The primary exposure variable was the number of intubation attempts. The primary outcome measure was the occurrence of peri-intubation major complications within 15 min of intubation including hypotension, hypoxemia, vomiting, dysrhythmias, cardiac arrest, esophageal intubation, and failed airway with cricothyrotomy. We constructed multivariable logistic regression models to determine the associations between complications and the number of intubation attempts while controlling for measured pre-exposure variables. There were 19,071 intubations in the NEAR database, of which 15,079 met inclusion for this analysis. Of these, 13,459 were successfully intubated on the first attempt, 1,268 on the second attempt, 269 on the third attempt, 61 on the fourth attempt, and 22 on the fifth or more attempt. A complication occurred in 2,137 encounters (14 %). Major complications accompanied 1,968 encounters (13 %) whereas minor complications affected 315 encounters (2 %). The most common major complication was hypoxia. In our multivariable logistic regression model, odds ratios with 95 % confidence intervals for the occurrence of major complications for multiple attempts compared to first-pass success were 4.4 (3.6–5.3), 7.4 (5.0–10.7), 13.9 (5.6–34.3), and 9.3 (2.1–41.7) for attempts 2–5+ (reference attempt 1), respectively. We found an independent association between the number of intubation attempts among ED patients undergoing emergency airway intubation and the risk of complications.
