Detection of Elevated Intracranial Pressure in Robot-assisted Laparoscopic Radical Prostatectomy Using Ultrasonography of Optic Nerve Sheath Diameter

摘要

Background: Robot-assisted laparoscopic radical prostatectomy (RALRP) is becoming an increasingly frequent procedure. Pneumoperitoneum and steep trendelenburg positioning associated with this surgery may increase patient's risk for elevated intracranial pressure (ICP). We conducted a prospective observational trial using ultrasonographic analysis of optic nerve sheath diameter (ONSD) to determine if ICP increased to levels >20 mm Hg during RALRP surgery.
