U.S., June 24 -- ClinicalTrials.gov registry received information related to the study (NCT07662538) titled 'Optic Nerve Sheath Diameter Changes During Bariatric Surgery' on June 16.
Brief Summary: This prospective clinical study aimed to evaluate the effects of pneumoperitoneum and patient positioning on intracranial pressure in patients undergoing bariatric surgery. Intracranial pressure was assessed noninvasively using ultrasonographic optic nerve sheath diameter (ONSD) measurements. ONSD measurements were performed before anesthesia induction in the supine position (T0), 5 minutes after anesthesia induction (T1), 5 minutes after creation of pneumoperitoneum and placement in the reverse Trendelenburg position (T2), at the 20th minute of...
