Abstract

Background: The effects of total intravenous anaesthesia (TIVA) on cerebral oxygenation in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP) have not been investigated. We examined the changes in jugular venous oxygen saturation (SjvO₂ ) and regional cerebral tissue oxygen saturation (rSO₂ ) during RALP under TIVA. Whether rSO₂ could reflect SjvO₂ was also examined.

Methods: Forty patients (ASA 1-2) undergoing RALP were enrolled. Measurements were obtained at eight time points during the operation.

Results: SjvO₂ did not decrease at any measurement point, whereas rSO₂ fell significantly 120 min after pneumoperitoneum in a steep Trendelenburg position (p <0.01). There was a weak correlation between SjvO₂ and rSO₂ (Pearson correlation coefficient =0.34; p <0.01). Bland-Altman analysis showed a wide interval for the limit of agreement (47%) between the two measurements.

Conclusions: These findings suggested that TIVA could be safely used for RALP. It was also demonstrated that rSO₂ did not accurately reflect SjvO₂ during RALP. Copyright © 2014 John Wiley & Sons, Ltd.
