Objective: To observe the prophylactic effect of granisetron on postoperative nausea and vomiting (PONV) after supratentorial craniotomy.
Methods: Seventy ASA I-II patients undergoing elective supratentorial craniotomy were randomly and double-bindly divided into two groups: control group (Group C, n = 35) and granisetron group (Group G, n = 35). All the patients received either 0.9% NS (Group C) or granisetron 3 mg (Group G) via intravenous injection. The incidences of postoperative nausea and vomiting were recorded at 24 h, 48 h, 72 h after supratentorial craniotomy.
Results: The incidence of PONV in Group G was lower than that in Group C (25.7% vs 57.1%, P < 0.01). The incidence of server nausea with vomiting or vomiting in Group G was lower than that in Group C (17.2% vs 48.6%, P < 0.01).
Conclusion: Granisetron can be used effectively and safely to prevent PONV in supratentorial craniotomy.
