Effect of Anesthetic Method on Optic Nerve Sheath Diameter in Patients Undergoing RALP

Effect of Anesthetic Method on Optic Nerve Sheath Diameter in Patients Undergoing Robot-assisted Laparoscopic Prostatectomy: Comparison of Sevoflurane-remifentanil and Sevoflurane-remifentanil-dexmedetomidine

The purpose of this study was to evaluate the effect of anesthetic method on the optic nerve sheath diameter in patients undergoing robot-assisted laparoscopic prostatectomy.

The purpose of this study was to evaluate the difference between the optic nerve sheath diameter measured during anesthesia with sevoflurane-remifentanil-dexmedetomidine and the optic nerve sheath diameter measured during anesthesia with sevoflurane-remifentanil in patients undergoing robot-assisted laparoscopic prostatectomy.

Inclusion Criteria:

• History of cerebral hemorrhage or cerebral infarction
• < 20 years of age
• ≥ 80 years of age
