Endotracheal intubation is frequently performed in the intensive care unit (ICU). It can be life-saving for many patients who present with acute respiratory distress. However, it is equally associated with complications that may lead to unwanted effects in this patient population. ⋯ This leaves the critical care clinician with uncertainty regarding the best sedative to administer in this patient population. The following editorial discusses current evidence regarding etomidate use for endotracheal intubation and mortality. In particular, we highlight a recent article with the largest population to date that found no association between etomidate and mortality in the critically ill and illustrate important findings that the reader should be aware of regarding this article.

Transfemoral transcatheter aortic valve implantation (TAVI) is nowadays a routine therapy for elderly patients with severe aortic stenosis (AS) and high perioperative risk. With growing experience, further development of the devices, and the expansion to "intermediate-risk" patients, there is increasing interest in performing this procedure under conscious sedation (TAVI-S) rather than the previously favoured approach of general anesthesia (TAVI-GA). The proposed benefits of TAVI-S include; reduced procedure time, shorter intensive care unit (ICU) length of stay, reduced need for intraprocedural vasopressor support, and the potential to perform the procedure without the direct presence of an anesthetist for cost-saving reasons. ⋯ General anesthesia and conscious sedation have both been used successfully to treat patients with severe AS undergoing TAVI with similar reported short and long-term mortality outcomes. The authors believe that the significant incidence of complications and unplanned conversion to general anesthesia during TAVI-S mandates the start-to-finish presence of an experienced cardiac anesthetist in order to optimize patient outcomes. Good quality randomized data is needed to determine the optimal anesthetic regimen for patients undergoing TAVI.
