comparison of the use of two methods of lidocaine and lubricant gel on reactions coming out of anesthesia with two methods of using laryngeal mask and endotracheal tube in patients undergoing cataract surgery: a randomized double-blind clinical trial study

Background: cataract surgery should have the least stimulation reactions after anesthesia due to high sensitivity. the results of studies on the severity and duration of hemodynamic changes caused by endotracheal intubation and laryngeal mask have not yet reached definitive results, so the study aims to compare lma and ett using two methods of lidocaine and lubricant gel on the reactions exit from anesthesia was performed in patients undergoing cataract surgery.methods: this randomized clinical trial study was conducted on 90 patients undergoing cataract surgery. patients were randomly divided in two groups and three subgroups receiving lidocaine gel, lubricant gel or normal saline. episodes of cough, sore throat, and nausea and vomiting were recorded in the ophthalmology department during recovery 1, 6, 12, and 24 hours after surgery.results: the findings of the present study show that the groups have no significant differences in terms of demographic characteristics. in the lubricant, lidocaine and normal saline groups, there was no significant difference between the lma and ett groups in terms of complications after leaving anesthesia.conclusion:in the lubricant, lidocaine and normal saline groups, there was no significant difference between the lma and ett groups in terms of complications after coming out of anesthesia. it is suggested to investigate this issue in different surgeries with more patients in future studies.
