Ketamine for procedural sedation and analgesia by nonanesthesiologists in the field: a review for military health care providers.

Military health care providers located in field environments frequently face situations in which procedural sedation and analgesia are necessary, without the advantage of sophisticated monitoring equipment. Ketamine is a unique agent that can be administered either intravenously or intramuscularly to produce predictable and profound analgesia, with an exceptional safety profile. We review the issues unique to ketamine and provide a practical guide for the use of ketamine for adult and pediatric patients in a field environment.
