Optic Nerve Sheath Diameter Changes During Laparoscopic Cholecystectomy in the Reverse Trendelenburg Position: Total Intravenous Anesthesia vs. Desflurane

What is known on this subject?Sonographically determined optic nerve sheath diameter (ONSD) has been proposed as a straightforward and non-invasive technique for detecting elevated intracranial pressure (ICP).Several studies have measured ONSD in different positions by comparing other anesthesia methods.However, studies on the reverse Trendelenburg position are limited. What this study adds?Ultrasonographically assessed ONSD as a representative metric for ICP is evaluated to assess the effects of desflurane and propofol-based total intravenous anesthesia in patients undergoing elective laparoscopic procedures in the reverse Trendelenburg position.
