Effect of intravenous hydrocortisone in preventing post operative sore throat followed by using laryngeal mask airway in patients undergoing urogenital surgeries

Post-operative sore throat is one of the unpleasant side effects due to air way management method durig anesthesia. The aim of this study is to evaluate the effect of intravenous hydrocortisone to preventing post operative sore throat followed by using laryngeal mask airway during urogenital surgery. To do this 60 patients who undergoing urogenital surgery randomly divided to 2 groups (each group n=30). First group recieved 100 mg of intravenous hydrocortisone and second (control) group recieved placebo with the same volume five minutes before anesthesia induction. At the end of the operation and after LMAs removal, patients will be asked about having sore throat, hours 2, 4 and 24 after operation. Sore throat degree will be measured using a four score rating scale by an anesthesiologist who will be unaware of the type of the solution injected before operation. Inclusion Criteria: Elective urogenital surgery, ASA physical status class I-II Exclusion Criteria: Patients refuse to participate into study, Upper respiratory tract abnormalities or infection, sore throat, abdominal surgery, first unsuccessful LMA insertion, patients with full stomach, emergency conditions, pregnancy and smoking. To compare the mean of the normal quantity variables t-test and to compare the abnormal variables Mann-Whitney test were used. Qualitive variables were compared in both groups using Fisher’s exact test. Analyses were done using SPSS 15.
