Abstract

Endotracheal intubation is an essential component within the skill set of anesthesia providers. Rapid arterial desaturation remains a primary risk factor during laryngoscopy and intubation. The risk for hypoxemia exists because during endotracheal intubation, patients are apneic or hypo-ventilating (Wong et al., 2017). Apneic oxygenation (AO) has been advocated to attenuate hypoxemia during endotracheal intubation (Pavlov et al., 2017).

The aim of this project was to assess for any knowledge deficits regarding AO among anesthesia providers and assess the willingness of these providers to include AO into their current practice. The project investigator conducted an education session involving the evidence-based literature findings of AO and its implementation during endotracheal intubation. A pre and post-teaching tool survey was administered to each participant to assess for any knowledge expansion regarding AO. Both the pre and post-teaching tool surveys were scored and given a quantitative value. These values were then computed into a mean, standard deviation, and variance. An “expansion of knowledge” regarding AO in this project was defined as a statistically significant improvement in the mean scores between both the pre and post-teaching tool surveys. A paired t-test was performed to determine the presence of any statistical significance. Statistical significance was considered using a p-value of 0.05.

A total of 12 anesthesia providers participated and were evaluated in this project. The mean, standard deviation, and variance for the pre-teaching tool surveys were: 81.6, 19.1, and 363.9, respectively. The mean, standard deviation, and variance for the post-teaching tool surveys were: 93.3, 16.9, and 288.9, respectively. The post-teaching tool survey mean score reflected expansion of AO knowledge when compared to the pre-teaching tool mean survey score (standard error of the mean [SEM]: 5.751; test statistic: 2.028; critical value: 1.795; p-value: 0.05). Fifty-eight percent of participants expressed a willingness to incorporate AO into their current practice.
