The Effects of Lateral 45° Downward Position on the Optic Nerve Sheath Diameter

NCT05185908 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 26

No results posted yet for this study

Summary

Trendelenburg position and carbon dioxide (CO2) pneumoperitoneum are in association with increased intracranial pressure (ICP) reflected by the optic nerve sheath diameter (ONSD). Measurement of ONSD by ultrasound (US) guidance can be used in the diagnosis of ICP. The investigators interrogated the effects of lateral 45° downward position and CO2 insufflation on ONSD in patients undergoing laparoscopic transperitoneal nephrectomy.
