Ultrasound optic nerve sheath diameter evaluation in patients undergoing robot-assisted laparoscopic pelvic surgery

Abstract

Following the interesting reading of the article “A randomised trial to compare the increase in intracranial pressure as correlated with the optic nerve sheath diameter during propofol versus sevoflurane-maintained anesthesia in robot-assisted laparoscopic pelvic surgery”, the authors comment some aspects about ocular ultrasonography to measure optic nerve sheath diameter as a tool to detect potential intracranial hypertension, pointing out the utility of Standardized A Scan technique for this purpose.
