What this Trial Is About
Objective: To compare the effects of volatile and intravenous anesthetics on pupillary function after general anesthesia using a portable infrared pupillometer. Design: A monocentric, prospective, double blinded randomized study. Patients: Patients who require elective Ear, Nose and Throat (ENT) surgery under general anesthesia. Interventions: Patients undergoing elective ENT surgery will be assigned to intravenous versus inhalative anesthesia and pupillometric parameters monitored postoperative, using an infrared pupillometer. Outcomes measures: Reported pupillometric parameters after intravenous and inhalative anesthesia. The purpose of this study is to compare general anesthesia techniques (volatile, intravenous) on postoperative changes in pupillary reactivity by using infrared pupillometry.
