The Evaluation of Optic Nerve Sheath Diameter in Patients Underwent Laparoscopic Colon and Gynecologic Surgeries During Trendelenburg Position.

Medipol University·observational·Posted Jun 11, 2020·Updated May 20, 2021

In Brief

An observational study evaluating Optic nerve sheath diameter for Colon Disease and Gynecologic Disease. Completed, enrolled 40 participants across 1 site.

Detailed Summary

It is difficult to measure the several levels of intracranial pressure during abdominal surgery, and direct monitoring with intracranial devices is often impossible. Measurement of optic nerve sheath diameter (ONSD) via ultrasonography has been developed as an alternative method for evaluating intracranial pressure. Increased intracranial pressure may cause in expanding of the optic nerve sheath and may increase the diameter. Therefore, measuring the diameter of the optic nerve sheath via ultrasonography is considered as a non-invasive, easy-to-apply and reliable method to evaluate intracranial pressure.
