Randomized Controlled Trial Comparative StudyComparison of A-line autoregressive index and observer assessment of alertness/sedation scale for monitored anesthesia care with target-controlled infusion of propofol in patients undergoing percutaneous vertebroplasty.
Percutaneous vertebroplasty (PV) with monitored anesthesia care (MAC) is a growing trend. Without adequate sedation, patient movement can affect and even interrupt the procedure during MAC. The aim of this study was to compare the performance of the auditory-evoked potential (AEP) index and the Observer Assessment of Alertness/Sedation (OAA/S) scale as indicators of depth of sedation in patients undergoing PV. ⋯ TCI propofol with AEP monitoring can provide less patient movement, better sedation, and higher surgeon satisfaction in patients during prone-position PV procedures than can TCI propofol with OAA/S monitoring.

Randomized Controlled TrialThe intermittent sequential compression device on the lower extremities attenuates the decrease in regional cerebral oxygen saturation during sitting position under sevoflurane anesthesia.
The sitting position has potential for serious complications such as cerebral ischemia and venous air embolism. This study investigated the effects of intermittent sequential compression device (SCD) on the changes in regional cerebral oxygen saturation (rSO2) during the sitting position. ⋯ The application of SCD to the lower extremities during sitting position under sevoflurane anesthesia was a simple and effective method to attenuate the decrease in cerebral oxygen saturation.

Randomized Controlled Trial Comparative StudyDeeper total intravenous anesthesia reduced the incidence of early postoperative cognitive dysfunction after microvascular decompression for facial spasm.
To investigate whether the depth of total intravenous anesthesia affects postoperative cognitive dysfunction. ⋯ Deeper total intravenous anesthesia can decrease the incidence of cognitive dysfunction in the early postoperative period.

Serial measurement of static and dynamic cerebrovascular autoregulation after brain injury.
In patients with neuronal injury, the knowledge of the status of cerebrovascular autoregulation can help to optimize the management of the cerebral perfusion pressure. This study characterizes dynamic and static cerebrovascular autoregulation during the first 7 days after severe traumatic brain injury or intracranial hemorrhage. ⋯ Daily measured dAR and sAR were impaired after brain injury with a nadir on day 4 and consecutive incomplete recovery over time.
