Ketamine Versus Co-administration of Ketamine and Propofol for Procedural Sedation in a Pediatric Emergency Department
- Conditions
- Procedural Sedation and Analgesia
- Interventions
- Registration Number
- NCT01387139
- Lead Sponsor
- University of Colorado, Denver
- Brief Summary
The purpose of this study is to compare the effectiveness of the co-administration of intravenous ketamine and propofol to intravenous ketamine as a single agent for procedural sedation in the pediatric emergency department. The investigators hypothesize that patients receiving co-administration of ketamine and propofol will have a lower rate of adverse events, compared to patients receiving ketamine for procedural sedation.
- Detailed Description
Procedural sedation and analgesia (PSA) is a frequent occurrence in pediatric emergency departments. The goals of PSA include maximizing analgesia and amnesia, and minimizing adverse events while ensuring stable cardiopulmonary function. For decades, ketamine has been the main pharmacologic agent used for pediatric PSA. Numerous studies support the use of ketamine for sedation, amnesia, and analgesia on children undergoing painful procedures in the emergency department setting. Research has continually shown ketamine to cause emergence phenomenon, laryngospasm and vomiting.
Propofol is a sedative-hypnotic widely used for procedural sedation in adult emergency departments. The advantages of propofol include rapid onset, with quick and predictable recovery time, and antiemetic effects. Disadvantages include dose-dependent hypotension, bradycardia, respiratory depression, as well as pain with injection. In addition, propofol does not provide any analgesia.
Ketamine and propofol administered together have been successfully utilized in a variety of settings, including dermatologic, cardiovascular, and interventional radiological procedures in children. The co-administration of ketamine and propofol has been shown to preserve sedation while minimizing the respective adverse events. When used in combination, doses administered of each can be reduced, while producing a more stable hemodynamic and respiratory profile. Furthermore, this combination may reduce the frequency of emergence reactions, vomiting, and the pain of propofol injection.
To date, there are no randomized controlled trials evaluating the co-administration of ketamine and propofol versus ketamine monotherapy for PSA in the Pediatric Emergency Department.

Group Intervention Description Ketamine Co-Administered with Propofol Ketamine Co-administered with Propofol 0.5 mg/kg ketamine and 0.5 mg/kg propofol with additional doses of 0.25 mg/kg ketamine and 0.25 mg/kg propofol as needed (maximum single dose based on 100 kg person) Ketamine Alone Ketamine 1.0 milligrams/kilogram (mg/kg) ketamine with additional doses of 0.5 mg/kg ketamine as needed (maximum single dose based on 100 kilogram (kg) person)
- Primary Outcome Measures
Name Time Method Frequency of Adverse Events From enrollment through completion of follow-up, up to 7 days We will record all adverse events during the sedation, and then perform a follow-up call to determine if any additional adverse events occured after discharge.
- Secondary Outcome Measures
Name Time Method Recovery Time Once Vancouver Sedation Recovery Scale Score reaches 18 or greater, on average less than 1 hour Time until the patient has a Vancouver Sedation Recovery Scale Score of 18 or greater.
Parent Satisfaction After procedure is completed, on average less than 1 hour Measured on a 10-point scale (1= least satisfied, 10= most satisfied)
Physician Performing Procedure Satisfaction After procedure is completed, on average less than 1 hour Measured on a 10-point scale (1= least satisfied, 10= most satisfied)
Nurse Satisfaction After procedure is completed, on average less than 1 hour Measured on a 10-point scale (1= least satisfied, 10= most satisfied)
Efficacy of Sedation After procedure is completed, on average less than 1 hour Efficacy is defined as:
1. The patient does not have unpleasant recall of the procedure.
2. The patient did not experience sedation-related adverse events resulting in abandonment of the procedure or a permanent complication or an unplanned admission to the hospital or prolonged emergency department (ED) observation
3. The patient did not actively resist or require physical restraint for completion of the procedure. The need for minimal redirection of movements should not be considered as active resistance or physical restraint.
4. The procedure was successful
