Effect of Intravenous Hydrocortisone on Preventing Postoperative Sore Throat Followed by Laryngeal Mask Airway Use in patients Undergoing Urogenital Surgeries.

Abstract

Postoperative sore throat is a common complication which can lead to discomfort after operation and delay in patients' returning to normal daily activities. The present study was carried out to evaluate the influence of intravenous hydrocortisone on preventing postoperative sore throat followed by laryngeal mask airway use. Sixty patients who were scheduled to undergo urogenital surgery were divided into two groups. Five minutes before anesthesia induction, 100 mg of intravenous hydrocortisone or placebo with the same volume were given to the patients randomly. At the end of the operation and after LMAs were removed, patients were asked about having sore throat at hours 2, 4 and 24 after operation. There were three and six cases of sore throat after operation in hydrocortisone and in placebo groups respectively which showed no significant statistical difference (P=0.472). No cases of moderate or severe pain were reported in any of the patients in both groups and no statistically significant difference was observed regarding pain severity in recovery, hours 2, 4 or 24 after operation. Based on the statistical data obtained from this research, administrating intravenous hydrocortisone five minutes before anesthesia induction has no effect on postoperative sore throat severity and degree in urogenital surgeries.
