Abstract

Purpose/Background

The induction of anesthesia using hypnotic sedatives, such as etomidate and midazolam, is common practice. Etomidate and midazolam are commonly employed in the induction of anesthesia in the septic patient population, each with its unique advantages and drawbacks. This scoping review aims to synthesize evidence on the effects of anesthetic induction with etomidate versus midazolam in adult septic patients, focusing on the incidence of mortality and associated adverse effects during hospitalization. The purpose is to establish a standard of care for anesthetic induction in this population.

Methods

A literature review was conducted from September 2022 to March 2023 utilizing CINAHL Complete, SCOPUS, Access Medicine, Cochrane Library, and PubMed databases. Over 100 articles were found utilizing our keywords, which included induction agent, etomidate, midazolam, critical illness, sepsis, septic shock, severe sepsis, mortality, and hospital length of stay. Of these, 25 articles met the author’s inclusion criteria and underwent Rapid Critical Appraisal (RCA) to assess the quality and validity of the studies. This appraisal yielded ten articles that were further synthesized and classified by their level of evidence table.

Results

Ten studies were examined to assess the effects of etomidate and midazolam on septic patients. The results showed that when etomidate is used to induce anesthesia in septic patients, it can lead to increased in-hospital mortality rates and longer ICU and hospital lengths of stay. Additionally, six studies found that etomidate can cause adrenal gland suppression. On the other hand, midazolam was associated with lower mortality rates when used to induce anesthesia in septic patients. However, there is insufficient data concerning its ability to produce profound anesthesia in septic patients without causing undesirable hemodynamic changes. Based on the available data, midazolam is considered to be the safer option for inducing anesthesia in septic patients.

Implications for Nursing Practice

The results of the scoping review support that etomidate usage is linked to longer stays in the ICU and hospital and higher hospital-wide mortality compared to midazolam. These findings indicate that the use of midazolam to induce anesthesia in septic patients is preferred but not without risks to patients. Anesthesia personnel should be educated when utilizing midazolam, blood pressure should be monitored closely, and timely intervention should be conducted to prevent hemodynamic changes. The results of this scoping review highlight the need for a standard of care to be established on what medications to use during the induction of anesthesia in septic patients. Further research is needed to guide nurse anesthesia practice for improved septic patient outcomes.
