No results posted yet for this study

Summary

Laparoscopic surgery is a widely used alternative to open surgery; Advantages include reduced bleeding and pain intensity, shorter hospital stay, and improved cosmetic results.

Laparoscopic surgery involves the creation of a carbon dioxide (CO2) pneumoperitoneum to facilitate a clear surgical view, which can result in increased intracranial pressure (ICP).

Ultrasonographic measurement of optic nerve sheath diameter (ONSD) is a simple, non-invasive, yet reliable technique for ICP assessment.Ultrasonographic assessment of optic nerve sheath diameter (ONSD) has been proposed as a non-invasive measurement of intracranial pressure.

Conditions
