Insights
A granisetron-droperidol combination effectively prevents postoperative vomiting in children undergoing tonsillectomy. This combination therapy showed superior results compared to individual antiemetics, with no significant adverse events observed.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Pharmacology
Background:
- Postoperative vomiting (POV) is a common complication in children following tonsillectomy.
- Effective antiemetic strategies are crucial for improving pediatric surgical outcomes.
Purpose of the Study:
- To compare the efficacy of a granisetron-droperidol combination versus individual antiemetics for preventing POV in pediatric tonsillectomy patients.
- To evaluate the safety and effectiveness of combined granisetron and droperidol in this specific surgical context.
Main Methods:
- Prospective, randomized, double-blind study involving 180 pediatric patients (4-10 years old).
- Patients received either granisetron, droperidol, or a combination intravenously after inhaled induction.
- Complete response was defined as no emesis and no need for rescue antiemetics within 24 hours post-anesthesia.
Main Results:
- The granisetron-droperidol group achieved a significantly higher complete response rate (97%) compared to granisetron alone (83%) and droperidol alone (60%) at 0-3 hours post-anesthesia.
- Similar superior efficacy was observed between 3-24 hours post-anesthesia, with the combination group at 97% complete response.
- No clinically significant adverse events were reported in any treatment group.
Conclusions:
- The combination of granisetron and droperidol is superior to monotherapy with either agent for preventing postoperative vomiting in children undergoing tonsillectomy.
- This combination offers a highly effective and safe antiemetic strategy for pediatric patients in this setting.
Unlabelled:
This study was performed to compare the efficacy of a granisetron-droperidol combination with each antiemetic alone to prevent postoperative vomiting after tonsillectomy with or without adenoidectomy in children. One hundred eighty pediatric patients, ASA physical status I, aged 4-10 yr, were enrolled in a prospective, randomized, double-blind investigation and assigned to one of three treatment regimens: granisetron 40 microg/kg (Group G), droperidol 50 microg/kg (Group D), or granisetron 40 microg/kg plus droperidol 50 microg/kg (Group GD) (n = 60 in each group). These drugs were administered i.v. after an inhaled induction. The same standard general anesthetic technique and postoperative analgesia were used throughout. The rate of complete response, defined as no emesis and no need for rescue antiemetic, 0-3 h after anesthesia was 83% in Group G, 60% in Group D, and 97% in Group GD (P = 0.029 versus Group G, P = 0.001 versus Group D). The corresponding rates 3-24 h after anesthesia were 83%, 55%, and 97% (P = 0.029 versus Group G, P = 0.001 versus Group D). No clinically important adverse events were observed in any of the groups. In conclusion, a granisetron-droperidol combination is superior to each antiemetic alone in complete response in children undergoing general anesthesia for tonsillectomy.
Implications:
We compared the efficacy of granisetron plus droperidol with each antiemetic alone for the prevention of postoperative vomiting in children. The granisetron-droperidol combination was highly effective against postoperative emesis.
