Background: Laryngeal mask airway (LMA) is using for control of breathing during short-period operation. The patients may experience hemodynamic changes during cuffing or cough, nausea, and vomiting after driving out the mask. This randomized double-blind study was performed to compare postoperative hemodynamic changes and emergence reactin frequencies with preoperative topical lidocaine jelly and lubricant gel in patients.

Materials and methods: Two groups of the patients consisted of 40 male in each group were candidate for elective varicocelectomy under general anesthesia. They were randomly assigned into two groups. The first group was received preoprative topical lidocaine jelly on LMA and the second group received preoperative lubricant jelly during LMA insertion. Gathered data was analyzed with SPSS-18 software using Chi – square and T-Student tests.

Results: Two groups were similar with demographic parameres as age and weight.

In the lidocaine jelly group hemodynamic changes and emergence reactions were lower than the lubricant jelly group.

Conclusion: Usage of preoperative lidocaine jelly during LMA insertion can decrease hemodynamic changes and emergence reactions frequencies.
