Randomized Controlled Trial Clinical Trial
Evaluation of propofol-ketamine anesthesia for children undergoing cardiac catheterization procedures.
The aim of this study was to assess the safety and efficacy of the continuous intravenous administration of a combination of propofol and ketamine for children undergoing cardiac catheterization procedures (CCP). Thirty-two children scheduled for CCP in a university teaching hospital were included in this prospective randomized study. Patients in group 1 (n = 15) were given a combination of propofol (25 microg/kg per minute) and ketamine (25 microg/kg per minute), whereas patients in group 2 (n = 17) received a combination of propofol (25 microg/kg per minute) and ketamine (12.5 microg/kg per minute) for the maintenance of anesthesia. ⋯ The time to awakening was significantly less in group 2 (P < 0.05). We conclude that a combination of propofol (25 microg/kg per minute) and two different doses of ketamine (25 and 12.5 microg/kg per minute, respectively) are safe and efficacious for CCP in children. Although the time to awaken was more in patients receiving 25 microg/kg per minute of ketamine compared to those receiving 12.5 microg/kg per minute of ketamine, it was well within acceptable limits.
