Abstract

Background: sore throat as one of the common postoperative challenges, with a prevalence of 65%, mandates more attention. Many therapeutic approaches have been tested; including ketamine gargle. This study compares the effect dexmedetomidine versus ketamine, both used as preoperative gargle, on the incidence and severity of postoperative sore throat in emergency surgical procedures. Materials and Methods: All patients undergoing emergency surgical procedures who referred to Shohadaye-Tajrish Hospital and needed anesthesia using succinylcholine for rapid sequence induction were considered as the target population and patients with ASA class 1-2, who aged 18-64 years, were enrolled. Inside the operating theatre, patients’ vital signs recorded and they were divided into ketamine and dexmedetomidine groups, each including 20 patients, receiving 0.5 mg/kg ketamine or 0.25µg/kg dexmedetomidine in 100cc water to gargle before induction of anesthesia. Standard similar anesthesia protocols were applied for all patients. In PACU sore throat was assessed using a visual analog scale (VAS) scoring. Results: in the ketamine group, 8 cases and in the dexmedetomidine group, 12 had dry throat (p= 0.150). The mean severity of the postoperative sore throat was 2.10± (minimum score of one and a maximum of 3) without significant difference between the two groups (p=0.344). mean diastolic pressure and SpO2 were significantly lower in the dexmedetomidine group compared with the ketamine group (p=0.047 and 0.001). Conclusion: both dexmedetomidine and ketamine gargle could be equally useful and effective in reducing postoperative sore throat.
