Insights
Intramuscular ondansetron significantly reduced vomiting in children receiving ketamine for procedural sedation. This finding supports ondansetron as an effective antiemetic for managing ketamine-associated nausea and vomiting.
Area of Science:
- Pediatric Emergency Medicine
- Pharmacology
- Clinical Trials
Background:
- Procedural sedation with ketamine is common in pediatric emergency departments.
- Ketamine administration can lead to significant nausea and vomiting, impacting patient recovery.
- Effective antiemetic strategies are needed to mitigate ketamine-associated gastrointestinal side effects.
Purpose of the Study:
- To evaluate the efficacy of intramuscular ondansetron in preventing ketamine-associated vomiting in children.
- To compare the incidence of vomiting between children receiving ketamine alone versus ketamine with intramuscular ondansetron.
Main Methods:
- A randomized, double-blind, placebo-controlled, parallel-group clinical trial was conducted.
- Participants included children aged 6 months to 16 years receiving ketamine for procedural sedation.
- Patients received either ketamine alone or ketamine plus intramuscular ondansetron.
Main Results:
- Vomiting occurred in 12.5% of patients receiving ondansetron versus 21.5% in the control group during recovery (P=0.03).
- Vomiting before discharge was significantly lower in the ondansetron group (1.8%) compared to the control group (9.2%) (P<0.001).
- Intramuscular ondansetron demonstrated a statistically significant reduction in ketamine-associated vomiting.
Conclusions:
- Intramuscular ondansetron is an effective intervention for controlling ketamine-associated vomiting in pediatric procedural sedation.
- The findings support the routine use of intramuscular ondansetron to improve outcomes for children receiving ketamine sedation.
Objective:
This study was conducted to determine the effect of intramuscular ondansetron on ketamine-associated vomiting in children undergoing procedural sedation.
Methods:
This randomized, double-blind, placebo-controlled, parallel-group clinical trial was conducted at the emergency departments of two university-affiliated tertiary care hospitals. Eligible participants included all 6-month to 16-year-old children who received IM ketamine for PSA in the ED. A convenience sampling approach was used and a block randomization method was applied (blocks of four) using a computer-generated random sequence. Patients received ketamine 4 mg/kg or ketamine 4 mg/kg plus ondansetron 0.1 mg/kg intramuscularly. All findings including the occurrence of vomiting and its frequency were then recorded in the data collection sheets.
Results:
Of 56 patients who received ondansetron plus ketamin, 7 (12.5%) and 1 (1.8%) experienced vomiting during recovery and before discharge and Of 65 patients in the control group, 14 (21.5%) and 6 (9.2%) experienced vomiting during recovery and before discharge, respectively. The observed differences in the rates of vomiting during recovery and at discharge were statistically significant between the two groups (P-value of 0.03 and <0.001, respectively).
Conclusion:
Intramuscular ondansetron is effective in controlling ketamine-associated vomiting.
