Protocol summary

Summary
This study was performed to evaluate the efficacy of intravenous dexamethasone plus ketamine gargle for reducing the incidence and severity of post operative sore throat and hoarseness. The main Inclusion criteria were : Patients between 18 and 65 years of age,with American society of anesthesiologists physical status (ASA) I–II, who were scheduled for elective surgery under general anesthesia in Kashni hospital of Isfahan city that requiring one-lung ventilation and the main exclusion criteria was; those who required more than one attempt for tracheal intubation.This double blind clinical trial was performed on140 patients. Patients were randomly allocated into four groups of 35 subjects each: before induction of anesthesia,Group K, gargled 40mg ketamine in 30 ml saline; Group D, were infused 0.2 mg/kg intravenous (IV) dexamethasone; Group KD, gargled 40mg ketamine in 30ml saline plus 0.2mg/kg intravenous dexamethasone; Group P (placebo) that received saline (gargle and IV). Post operative sore throat and hoarseness were graded at 0, 2, 4,8,16 and 24 h after operation on a four-point scale.
