Insights
Ondansetron effectively reduced postanesthesia shivering in children who received caudal anesthesia. This study confirms ondansetron
Area of Science:
- Anesthesiology
- Pediatric Anesthesia
- Pharmacology
Background:
- Postanesthesia shivering is a common complication in children.
- Ondansetron's efficacy in reducing shivering in adults is known.
- Limited research exists on ondansetron for pediatric postanesthesia shivering.
Purpose of the Study:
- To investigate the effectiveness of ondansetron in preventing postanesthesia shivering in children undergoing caudal anesthesia.
- To evaluate ondansetron's impact on shivering severity and incidence in pediatric patients.
Main Methods:
- A randomized controlled trial involving 59 children aged 8-13 years.
- Children received either ondansetron (4 mg IV) or normal saline post-anesthesia.
- Physiological parameters and shivering scores were monitored.
Main Results:
- Ondansetron significantly decreased the likelihood of postanesthesia shivering.
- A notable reduction in shivering score over time was observed in the ondansetron group.
- No adverse effects were mentioned in the abstract.
Conclusions:
- Ondansetron is effective in reducing postanesthesia shivering in children.
- This finding supports the use of ondansetron for pediatric patients receiving caudal and intravenous anesthesia.
- Further research may explore optimal dosing and long-term effects.
Background:
Ondansetron has been shown to decrease postanesthesia shivering in adults, but this effect has never been studied in children. This study aimed to determine whether ondansetron decreases postanesthesia shivering in children undergoing caudal anesthesia.
Methods:
Fifty-nine 8- to 13-y-old children undergoing both intravenous and caudal anesthesia were included. As soon as anesthetization and caudal block were complete, children were given intravenous injections of 4 mg ondansetron or an equal volume of normal saline. Heart rate, blood pressure, oxygen saturation (SpO2), and body temperature were recorded just before application of general anesthesia to children and immediately upon entry into the recovery room after awakening from anesthesia. The shivering score was assessed, using a 4-point scale of severity, immediately upon entry into the recovery room after awakening from anesthesia, 15 min after entry into the recovery room, and 30 min after entry into the recovery room.
Results:
Treatment with ondansetron was associated with decreased odds of postanesthesia shivering symptoms compared to the control group. There was also a significant decrease in shivering score with time after anesthesia.
Conclusion:
Ondansetron decreases postanesthesia shivering in children receiving caudal block after intravenous anesthesia.
