Comparing the effect of positioning on cerebral autoregulation during radical prostatectomy: a prospective observational study.

Purpose: Surgery in the prolonged extreme Trendelenburg position may lead to elevated intracranial pressure and compromise cerebral hemodynamic regulation. We hypothesized that robot-assisted radical prostatectomy with head-down tilt causes impairment of cerebral autoregulation compared with open retropubic radical prostatectomy in the supine position.

Methods: Patients scheduled for elective radical prostatectomy were included at a tertiary care prostate cancer clinic.

Postanesthesia care unit delirium following robot-assisted vs open retropubic radical prostatectomy: A prospective observational study.

Background: The aim of this study was to compare the incidence of early postoperative delirium in the postanesthesia care unit (PACU) between robot-assisted radical prostatectomy (RARP) in the extreme Trendelenburg position and open retropubic radical prostatectomy (ORP) in supine position.

Methods: Patients were screened for delirium signs 15, 30, 45, and 60 minutes following extubation.

Results: PACU delirium was present in 39.
