Intranasal ketamine is very attractive in austere and alpine environments, where monitoring capabilities slow transport and IV access is difficult. Previous case reports suggest that IN ketamine provides a rapid, easily administered and effective method of analgesia in the pre-hospital setting (7). However, there is no data on the feasibility of conducting a medical trial in a large busy commercial ski area, nor to calculate an appropriate sample size. The investigators propose a pilot study to investigate the feasibility of conducting a study of IN ketamine (INK) prior to a larger study to determine if INK provides an effective and safe method of analgesia for patients presenting to ski patrol with acute injuries. In addition, although the current body of literature shows minimal adverse events, the investigators will continue to study the safety of INK and monitor for any negative side effects. The purpose is to provide insight and information on the potential utility of IN ketamine in this setting, and to assess feasibility of future clinical trials powered to demonstrate efficacy and safety.
