Background : Local anesthesia for eye surgery is increasingly popular, but there will always be a need for general anesthesia. Cough during emergence from general anesthesia is considered critical event as it may lead to surgical bleeding laryngospasm hemodynamic instability and could be life threatening in patients who are at risk of complications related to increase in intracranial or intraocular pressure. Objectives: To detect the effect of intratracheal lidocaine on cough reflex in eye surgery. Study design: Prospective randomized double blind controlled study will be conducted on 80 adult patients. Methods: This study involved 80 patients who are undergoing general anesthesia for elective keratoplasty and retinal detachment. The patients will be allocated into 2 groups (40 patients on each group). 40 patients Received (5ml) 2% of lidocaine was sprayed down the intratracheal tube of patients while 40 patients Received 5ml saline in medical spray bottle was sprayed down intratracheal tube of patients. observed variables included hemodynamic parameters, intraocular pressure, postoperative cough, surgeon satisfaction and complications related to drugs. Results: The results have shown that lidocaine was more effective in attenuating cough in eye surgery, and provide satisfactory analgesic effect after surgery. Conclusion: lidocaine was more effective in attenuating cough in eye surgery, and provide satisfactory analgesic effect after surgery
