چکیده

STUDY OBJECTIVE The primary objective is to compare total sedation time when ketamine/propofol is used compared with ketamine alone for pediatric procedural sedation and analgesia. Secondary objectives include time to recovery, adverse events, efficacy, and satisfaction scores. METHODS Children (aged 2 to 17 years) requiring procedural sedation and analgesia for management of an isolated orthopedic extremity injury were randomized to receive either ketamine/propofol or ketamine. Physicians, nurses, research assistants, and patients were blinded. Ketamine/propofol patients received an initial intravenous bolus dose of ketamine 0.5 mg/kg and propofol 0.5 mg/kg, followed by propofol 0.5 mg/kg and saline solution placebo every 2 minutes, titrated to deep sedation. Ketamine patients received an initial intravenous bolus dose of ketamine 1.0 mg/kg and Intralipid placebo, followed by ketamine 0.25 mg/kg and Intralipid placebo every 2 minutes, as required. RESULTS One hundred thirty-six patients (67 ketamine/propofol, 69 ketamine) completed the trial. Median total sedation time was shorter (P=0.04) with ketamine/propofol (13 minutes) than with ketamine (16 minutes) alone (Δ -3 minutes; 95% confidence interval [CI] -5 to -2 minutes). Median recovery time was faster with ketamine/propofol (10 minutes) than with ketamine (12 minutes) alone (Δ -2 minutes; 95% CI -4 to -1 minute). There was less vomiting in the ketamine/propofol (2%) group compared with the ketamine (12%) group (Δ -10%; 95% CI -18% to -2%). All satisfaction scores were higher (P<0.05) with ketamine/propofol. CONCLUSION When compared with ketamine alone for pediatric orthopedic reductions, the combination of ketamine and propofol produced slightly faster recoveries while also demonstrating less vomiting, higher satisfaction scores, and similar efficacy and airway complications.

Effect of Ondansetron on the Incidence of Ketamine Associated Vomiting in Procedural Sedation and Analgesia in Children: A Double-Blind, Randomized, Placebo-Controlled Trial

Background Vomiting is a common side effect of ketamine in children's sedation and there is still controversy about the use of an anti-emetic drug along with ketamine to reduce this complication. The aim of this study was to evaluate the effectiveness of ondansetron in controlling vomiting induced by intramuscular (IM), and intravenous (IV) ketamine for procedural sedation and analgesia in chil...

Effect of two Different Concentrations of Propofol and Ketamine Combinations (Ketofol) in Pediatric Patients under Lumbar Puncture or Bone Marrow Aspiration

Abstract Background Ketamine is an anesthetic drug that is importantly analgesic without respiratory depression. Ketamine increases blood pressure and heart rate. Propofol is an anesthetic drug with good sedation, rapid recovery, but it causes respiratory depression, low heart rate and low blood pressure. Combination of Ketamine and Propofol provides sedation, analgesia and rapid recovery wit...
