Background: The incidence of propofol injection pain during induction of general anesthesia varies from 28% to 90%. This prospective, randomized, double-blind, placebo-controlled study evaluated the effect of dexamethasone and granisetron for reducing the incidence and severity of propofol injection pain. Materials and Methods: A total of 227 female subjects received 5 mL of preservative-free saline, 1 mg granisetron (5 ml), or 0.15 mg/kg of dexamethasone (5 ml), intravenously, following exsanguination and occlusion of the veins of the arm. This was followed by a 0.5 mg/kg injection of propofol. Pain scores and intensity of pain recorded immediately following the injection of propofol. Hemodynamic parameters and O2sat were recorded 1, 3, 5, and 10 min after propofol injection. Results: The incidence pain following the injection of propofol was significantly decreased with both granisetron and dexamethasone (50.7% and 49.4%). Mean pain score in granisetron group was 3.16 ± 1.23, dexamethasone was 2.73 ± 1.03, and in saline group was 4.82 ± 1.73 (P = 0.001). Mean pain intensity in granisetron group was 1.16 ± 0.18, dexamethasone was 1.26 ± 0.14, and in saline group was 2.2 ± 0.99 (P = 0.001). There were no differences in either mean arterial pressure or O2Sate at any time point after drugs injection among the groups. There was a significant difference in pulse rate in third minutes between three groups and in the group who received granisetron was lesser (P = 0.04). Conclusion: Pretreatment with intravenous granisetron (1 mg) and dexamethasone (0.15 mg/kg) before injection of propofol is effective and safe in reducing the incidence and severity of pain due to propofol injection.
