Abstract
In patients presenting for pyloromyotomy, most practitioners prioritize rapid securement of the airway due to concern for aspiration. However, there is a lack of consensus and limited evidence on the choice between rapid sequence induction (RSI) and modified RSI (mRSI). The medical records of all patients presenting for pyloromyotomy from May 2012 to December 2018 were reviewed. The risk of hypoxemia (peripheral oxygen saturation [Spo2], <90%) during induction was compared between RSI and mRSI cohorts for all patients identified as well as in the neonate subgroup by univariate and multivariable logistic regression analysis. Complications (aspiration, intensive care unit admission, bradycardia, postoperative stridor, and hypotension) and initial intubation success for both cohorts were also compared. A total of 296 patients were identified: 181 in the RSI and 115 in the mRSI cohorts. RSI was associated with significantly higher rates of hypoxemia than mRSI (RSI, 30% [23%-37%]; mRSI, 17% [10%-24%]; P = .016). In multivariable logistic regression analysis of all patients, the adjusted odds ratio (OR) of hypoxemia for RSI versus mRSI was 2.8 (95% confidence interval [CI], 1.5-5.3; P = .003) and the OR of hypoxemia for multiple vers...Continue Reading
