articleOBJECTIVE: Volatile anesthetics (VAs) are gaining renewed interest as a sedation strategy in the intensive care, offering an alternative to traditional IV agents. VAs provide several pharmacologic advantages, including rapid onset and offset, minimal systemic metabolism, and favorable recovery profiles. Advances in delivery systems enabled the safe and practical administration of volatile agents in the ICU. Thus, we aimed to describe the pharmacology and safety aspects of inhaled agents as well as the systems designed to deliver VAs in the ICU. DATA SOURCES: Relevant literature was identified through PubMed and MEDLINE databases. STUDY SELECTION: Original research, review articles, commentaries, and guidelines addressing safety, efficacy, and use of VAs in adult ICU patients were included. DATA EXTRACTION: Studies were reviewed by the authors, with key findings summarized and organized by pharmacologic properties, delivery systems, and safety domains. DATA SYNTHESIS: VAs are halogenated hydrocarbons whose mechanism of action is not fully understood. Although the CNS is the primary site of action, the end-tidal concentration of exhaled anesthetic is used to monitor clinical effects such as immobility to a noxious stimulus. Inhaled agents have unique pharmacokinetics, minimal metabolisms, and distinct recovery. The side effect profile is also unique, with malignant hyperthermia being the most feared, yet rare complication. Two systems for inhalational sedation delivery are available internationally, with one currently under evaluation in the United States. The systems are composed of a miniature vaporizer, delivery controller, and a monitor. The systems have distinct safety considerations, such as tidal volume limits. CONCLUSIONS: VAs can be used as sedative agents in the ICU. This article comprehensively reviews the pharmacology of VAs along with their safety profile and describes the structure and function of miniature vaporizers currently available on the world market.

preprintOpen access1st authorCorrespondingA patient suffered a non-fatal wet drowning in a freshwater lake and developed bacteremia several days later. Blood culture grew a Gram-negative rod that could not be identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). 16S ribosomal RNA sequencing of the isolate identified the microbe as Hydrogenophaga laconesensis––an environmental microbe commonly found in freshwater. The recovery of multiple pathogenic microorganisms (although not H. laconesensis) from culture of respiratory specimens prompted the initiation of antibiotic therapy with cefepime and, later, vancomycin. The patient’s clinical course gradually improved over the course of two weeks and she was ultimately discharged home with minimal sequelae. To our knowledge, this is the first evidence of human infection with bacteria in the Hydrogenophaga genus. Hydrogenophaga may be considered in cases of freshwater near-drowning, and MALDI-TOF MS databases should be updated to include H.laconesensis.
