Impact of mannitol on intracranial pressure assessed by optic nerve sheath ultrasonography during video-laparoscopic prostatectomy: a randomized clinical trial

Mannitol administration during video-laparoscopic prostatectomy did not result in significant differences in ONSD trajectory or extubation time compared with the control group. At the dose and timing used, mannitol did not modify intraoperative surrogate measures of intracranial pressure.
