Common anesthetics such as isoflurane and sevoflurane rapidly reach sedative levels in the body, but they are also rapidly eliminated, allowing for quick recovery. These agents have minimal impact on the liver and kidneys, which makes them attractive options when compared to other agents including opioids, benzodiazepines, ketamine, and propofol. Use of delivery systems like AnaConDa\u00ae (Anaesthetic Conserving Device; Sedana Medical AB, Danderyd, Sweden) has enabled providers to easily use these agents in the Intensive Care Unit (ICU). In this regard, they have recently provided additional beneficial consideration during intravenous drug shortages seen during the COVID-19 pandemic and at other times. These agents have shown organ-protective effects in the kidneys and lungs, which may even reduce the total time spent in the ICU. Pharmacodynamically, these anesthetics mediate their effects through central nervous system ion channels to exert analgesic and anxiolytic actions, thereby minimizing effects in the kidneys and lungs. These agents are primarily eliminated via exhalation, which makes them potential options for those with liver or kidney failure. This narrative review examines current efficacy and risks of using volatile anesthetics for sedation in the ICU setting and clinical roles for the future.<\/jats:p>","DOI":"10.3390\/diseases14040117","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T12:05:49Z","timestamp":1775563549000},"page":"117","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Critical Care Sedation: Emerging Clinical Considerations and Risks of Volatile Anesthetics for Sedation: A Narrative Review"],"prefix":"10.3390","volume":"14","author":[{"given":"Austin M.","family":"Breaux","sequence":"first","affiliation":[{"name":"School of Medicine, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Garret R.","family":"Miller","sequence":"additional","affiliation":[{"name":"School of Medicine, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6995-891X","authenticated-orcid":false,"given":"Harrison D.","family":"Cooper","sequence":"additional","affiliation":[{"name":"School of Medicine, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristin Nicole","family":"Bembenick","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aishwarya","family":"Reddy","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shahab","family":"Ahmadzadeh","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4545-4523","authenticated-orcid":false,"given":"Sahar","family":"Shekoohi","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2464-0187","authenticated-orcid":false,"given":"Alan D.","family":"Kaye","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA 71103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"90746","DOI":"10.5492\/wjccm.v13.i1.90746","article-title":"Inhaled volatile anesthetics in the intensive care unit","volume":"13","author":"Wieruszewski","year":"2023","journal-title":"World J.
