The aim of this study was to assess the impact of intravenous general anesthesia and controlled hypotension on cerebral saturation (rScO2), cerebral blood flow measured as middle cerebral artery blood flow velocity (Vmax MCA) and neurobehavioral outcome in patients scheduled for shoulder surgery in beach chair position. ⋯ In ASA I-II patients intravenous general anesthesia and controlled hypotension in the beach chair position affects cerebral blood flow and cerebral oxygenation with impact on the neurobehavioral outcome.

Intravenous patient-controlled opioid analgesia (IVPCA), epidural analgesia and transversus abdominis plane (TAP) infiltrations are frequently used postoperative pain management modalities. The aim of this study was to conduct a cost-effectiveness analysis comparing the use of epidural, IVPCA, and TAP infiltrations with liposomal bupivacaine for analgesia in the first 72 h postoperatively in patients undergoing major lower abdominal surgery. ⋯ This is the first study in the literature to compare the cost-effectiveness of epidural, IVPCA, and TAP infiltrations with LB. Within reasonable WTP values, there is little differentiation in cost-effectiveness between IVPCA and TAP infiltration with LB. Epidural does not become a cost-effective strategy even at much higher WTP values.
