Randomized Controlled Trial
Comparison of the effects of desflurane and total intravenous anesthesia on the optic nerve sheath diameter in robot assisted laparoscopic radical prostatectomy: A randomized controlled trial.
Medicine (Baltimore) 2018 October
BACKGROUND: Optic nerve sheath diameter (ONSD) is a well-known surrogate marker for intracranial pressure during robot-assisted laparoscopic radical prostatectomies (RALP). ONSD during RALP is known to increase due to elevated intracranial pressure as a result of the steep Trendelenburg position and carbon dioxide pneumoperitoneum. We aimed to compare the effects of total intravenous anesthesia (TIVA) and desflurane anesthesia (DES) on ONSD during RALP.
METHODS: Patients scheduled for RALP were enrolled and randomly assigned to the TIVA (propofol and remifentanil) or DES (desflurane and remifentanil) group in this randomized trial. Ultrasonographic measurements of ONSD were conducted before administration of anesthesia (T0), 10 minutes after the Trendelenburg position (T1), 1 hour after the Trendelenburg position (T2), 2 hours after the Trendelenburg position (T3), 10 minutes after resuming the supine position (T4), and at the time of arrival in the post-anaesthetic care unit (T5). The primary outcome measure was the mean ONSD at T2 of the TIVA and DES group during RALP.
RESULTS: A total of 56 patients were analysed in this study. The mean ONSD at T1, T2, T3, and T4 were significantly lower for patients in the TIVA group compared with those in the DES group (P = .023, .000, .000, and .003, respectively).
CONCLUSION: The mean ONSD for patients in the TIVA group was significantly lower than that in the DES group during the RALP procedure. Our findings suggest that TIVA may be a more suitable anesthetic option for patients at risk of cerebral hypoperfusion.
