AI Article Synopsis
- The study aimed to compare the safety and effectiveness of etomidate and ketamine for rapid sequence intubation (RSI) in acutely ill patients, focusing on incidents of hypotension and success of first-pass intubation.
- A systematic review of 87 records yielded 9 eligible studies, showing that etomidate reduced the risk of post-induction hypotension compared to ketamine, but there was no significant difference in first-pass intubation success rates between the two drugs.
- Overall, etomidate may be a safer option for induction in RSI due to its lower risk of hypotension, while both agents perform similarly in intubation success.
Article Abstract
Aims And Objectives: The objective of the study was to compare the safety and efficacy of etomidate and ketamine as induction agents for rapid sequence intubation (RSI) in acutely ill patients in emergency department and prehospital settings with respect to post-induction hypotension and first-pass intubation success during RSI.
Materials And Methods: For this systematic review and meta-analysis, we searched PubMed, Embase, Cochrane, and ClinicalTrials.gov between database inception and June 1, 2021. Articles were included if they compared safety and efficacy of etomidate vs ketamine as induction agents, in patients undergoing RSI in emergency department and prehospital settings, without any restrictions on study design. The outcome measures were incidence of post-induction hypotension and first-pass intubation success. The dichotomous outcomes were assessed for odds ratio (OR) with 95% confidence interval (CI) using random-effects meta-analysis.
Results: Of 87 records identified, 9 were eligible, all assessed as having a low to moderate risk of overall bias. Six studies, including 12,060 patients from prehospital emergency medical services, air medical transport, and emergency department settings, compared post-induction hypotension incidence between etomidate and ketamine groups. The meta-analysis showed that etomidate was associated with decreased risk of post-induction hypotension compared to ketamine (OR: 0.53; 95% CI: 0.31-0.91; = 68%). Seven studies, including 15,574 patients, reported on the rate of first-pass intubation success with etomidate vs ketamine. In the pooled analysis, no differences were seen in first-pass intubation success during RSI using etomidate vs ketamine as the induction agent (OR: 1.13; 95% CI: 0.95-1.36; = 16%).
Conclusion: The use of etomidate for induction during RSI is associated with a decreased risk of post-induction hypotension as compared to the use of ketamine, without an impact on the first-pass intubation success rate.

Prevention of sufentanil-induced cough during induction of general anesthesia by low-dose esketamine.
BMC Anesthesiol
January 2025
Department of Anesthesiology, Air Force Medical Center, No.30 Fucheng Road, Haidian District, Beijing, 100142, China.
Background: Sufentanil is commonly used to induce general anaesthesia due to its rapid onset of action, strong analgesic effect, long-lasting effect, and stable haemodynamics; however, it often induces cough, increasing the risk of anaesthesia. This study aimed to investigate the preventive effect of low-dose esketamine on sufentanil-induced cough.
Methods: This randomised, double-blind, placebo-controlled clinical study was conducted at the Air Force Medical Center between September 2023 and May 2024.

Background: The limited and detailed literature on total intravenous anesthesia (TIVA), as well as the clinical indications for unilateral ovariectomy in llamas, are not well-defined. Therefore, it is necessary to understand the anesthetic events and the surgical intervention in this species.
Aim: The objective of this study was to evaluate the intraoperative physiological and clinical parameters in llamas undergoing unilateral ovariectomy, under three protocols of TIVA.
