Aims To compare the safety and efficacy of 1 and 3 mg of granisetron in the prevention of postoperative nausea and vomiting (PONV) in strabismus surgeries under general anesthesia.
Settings and design This single-blinded, randomized, controlled trial was conducted at the ophthalmology operating theater of Kasr Al-Ainy Hospitals.
Patients and methods We recruited 210 patients and allocated them randomly to receive either granisetron 1 mg (n=105) or 3 mg (n=105). The two groups were compared regarding demographic data, hemodynamic parameters, and percentage of patients with no complaints of PONV during the first 24 h.
Results There was no statistically significant difference upon comparison of the two groups regarding PONV (P>0.05). The two doses (1 and 3 mg) provided total control of nausea and vomiting in 46.7 and 43.8% of patients during the first 24 h postoperatively, respectively. Moreover, we found no significant difference between the two groups regarding mean values of the heart rate or mean arterial pressure both preoperatively and intraoperatively (P>0.05). However, during the postoperative 24 h, both groups had significant differences regarding mean values of heart rate and mean arterial pressure at 2–4 h, 8–12 h, and 12–24 h postoperatively.
Conclusions The comparison between two doses of granisetron (1 and 3 mg) showed no statistical difference regarding the total control of nausea and vomiting for 24 h postoperatively but showed a statistical difference regarding some postoperative vital sign readings.
