Comparative Study
[Relationship between postoperative neurological complications and regional cerebral oxygen saturation during retrograde cerebral perfusion].
Transient postoperative neurological disorders are common in patients undergoing aortic surgery with retrograde cerebral perfusion (RCP). We evaluated the relationship between transient postoperative neurological disorders and regional cerebral oxygen saturation (rSO2) during RCP. ⋯ The rSO2 monitor could detect the decrease of cerebral perfusion during RCP. The wide asymmetry of rSO2 was associated with transient neurological disorders, although the lowest rSO2 value and the rate of decline did not relate.

Comparative Study
[Basic study on the mechanism of postanesthetic recovery acceleration caused by infusion of bicarbonated Ringer's solution].
Effect of bicarbonated Ringer's solution (BRS) on the liver function of rats with metabolic acidosis was compared with that of lactated Ringer's solution (LRS) and Ringer's solutions (RS). Furthermore, the effect of acidosis on the plasma protein binding ratio of propofol was examined. ⋯ These results suggest that metabolic acidosis induced the delay of awakening from anesthesia, suggesting that BRS accelerates recovery from anesthesia through amelioration of acidosis.

Case Reports
[Complications of internal jugular vein cannulation under ultrasound guidance: report of three].
Internal jugular cannulation with ultrasound guidance has been advocated to decrease its complications. However, there can be serious complications by in-experienced physicians in even ultrasound-guided internal jugular vein cannulation. We report three cases of complications associated with ultrasound-guided internal jugular vein cannulation: puncture of the common carotid artery in two patients and pneumothorax in one.

Co-administration of ketamine and remifentanil may offer preemptive analgesia and prevention of opioid-induced hyperalgesia, resulting in reduction of postoperative pain. ⋯ Results in this study suggest that anesthetic management using ketamine and remifentanil may be useful for postoperative pain management, probably by preemptive analgesic effects of both agents and preventive effects of ketamine against opioid-induced hyperalgesia.
