Abstract:
A high incidence of vomiting after tonsillectomy is consistently reported in the literature. Multiple trials with different pharmacological agents and alternative anesthetic techniques have been used in an attempt to decrease this, but results have been inconclusive and adverse effects occur frequently. The purpose of this study was to examine the safety and efficacy of granisetron (Kytril) in the prevention of postoperative vomiting in children undergoing tonsillectomy. Fifty-four patients were included in this study. The study population was divided into an experimental (n = 28) and control group (n = 26) using a randomized double-blinded technique. The experimental group was treated with granisetron 10 micrograms/kg intravenously (IV) and the control group received saline solution IV. Episodes of vomiting were recorded throughout the hospital stay and for the 24 hours after surgery. A reduction in the incidence and severity of vomiting was shown to be significant in the experimental group, both in the hospital and at 24 hours postoperatively. High patient satisfaction was also reported in this group. Clinically, the prophylactic administration of granisetron intraoperatively in pediatric tonsillectomy patients should be considered to reduce the incidence and severity of postoperative vomiting.
Insights
Granisetron significantly reduced postoperative vomiting in children after tonsillectomy. This study shows granisetron (Kytril) is safe and effective for preventing nausea and vomiting in pediatric patients.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Pharmacology
Background:
- Post-tonsillectomy nausea and vomiting (PONV) is a common complication.
- Previous interventions for PONV have yielded inconclusive results and frequent adverse effects.
Purpose of the Study:
- To evaluate the safety and efficacy of granisetron for preventing PONV in pediatric tonsillectomy patients.
- To assess the impact of granisetron on patient satisfaction.
Main Methods:
- A randomized, double-blinded study involving 54 pediatric patients undergoing tonsillectomy.
- Patients received either granisetron (10 mcg/kg IV) or a saline placebo intravenously.
- Vomiting episodes were monitored during hospitalization and for 24 hours post-surgery.
Main Results:
- Granisetron significantly reduced the incidence and severity of vomiting in the hospital and at 24 hours postoperatively.
- The granisetron group reported higher patient satisfaction.
- No significant adverse effects were noted with granisetron administration.
Conclusions:
- Prophylactic intraoperative granisetron is a safe and effective strategy for reducing PONV in pediatric tonsillectomy patients.
- Granisetron administration should be considered for routine use in this patient population.
- Improved patient outcomes and satisfaction can be achieved with granisetron prophylaxis.
