Brief Summary: IntroductionConditions
Numerous drugs and combinations of drugs are used for procedural sedation and analgesia (PSA) in Emergency Departments, including propofol, ketamine, benzodiazepines, narcotics, barbiturates, and others, but propofol has gained popularity despite its potential to cause cardiac and respiratory depression. Obviously the optimal agent or combination of agents has not been identified. There are reasons to believe that a combination of ketamine and propofol may have advantages over other agents/combinations. These include better hemodynamic stability at equal depth of anesthesia with a combination of ketamine/propofol than with propofol alone, less respiratory depression with the combination in comparison to propofol alone, and preservation of respiratory drive with the combination. There is one study of ketamine/propofol in Emergency Department (ED) procedural sedation which demonstrated the safety and effectiveness of the combination, but did not compare it to any other agents or combinations. The investigators designed a randomized, placebo controlled study to compare propofol to propofol and ketamine for adequacy of sedation and respiratory depression in Emergency Department procedural sedation and analgesia. The investigators hypothesis was that the combination of propofol/ketamine would produce better sedation and/or less respiratory depression than propofol alone.
The investigators conducted a randomized, prospective, double-blinded study of all patients receiving procedural sedation. From April 2007 until July 2009 in the ED of a 274 bed university teaching hospital. The study was approved by the University of Missouri's Institutional Review Board and informed consent was obtained from all participants.
