A 77-year-old man scheduled for coronary artery bypass grafting underwent left superficial temporal artery-middle cerebral artery anastomosis (STA MCA). Before anesthesia, we planned to insert an intraaortic balloon pump as a perioperative circulatory assist. In addition, a fiberoptic catheter was inserted in the proximity of the right jugular bulb to monitor jugular venous oxygen saturation (Sjv(O2)) as an index of the balance between cerebral blood flow (CBF) and cerebral metabolic rate for oxygen (CMRO2). ⋯ Sjv(O2) is normally approximately 55-75%. If Sjv(O2) is < 50%, therapy (s) directed at increasing CBF and/or decreasing CMRO2 should be initiated. Sjv(O2) monitoring can be used to determine the minimal blood pressure that should be maintained to avoid cerebral ischemia in the case of STA-MCA.

Femoral nerve block and sciatic nerve block are used to provide intraoperative and postoperative analgesia for total knee arthroplasty. Sciatic nerve block is contraindicated in our hospital, because orthopedists want to assess peroneal nerve function after the surgery. We retrospectively assessed postoperative analgesic effect and complications of the continuous femoral nerve block for total knee arthroplasty. ⋯ Femoral nerve separation with 5% glucose solution using in-palne method and catheter placement with out-of-plane method could be useful for perineural catheter placement. Perineural infusion of 0.15% ropivacaine at 4 ml x hr(-1) combined with IV-PCA provided a good postoperative analgesia in patients receiving total knee arthroplasty.

Previous reports indicate that Prader-Willi syndrome may present various problems during anesthesia and the perioperative period. We retrospectively investigated anesthesia records of 10 patients (2 adults and 8 children) who were diagnosed to have Prader-Willi syndrome, and who had an operation under anesthesia. Three patients had small mouths, small jaws or both. ⋯ Difficult tracheal intubation occurred in one patient. No other major problems occurred. We conclude that the incidence of problems during anesthesia and postoperative period in patients with Prader-Willi syndrome would be less than previously considered.

A 31-year-old female, with 22 weeks of pregnancy, presented with sudden onset of severe headache. CT scan showed diffuse subarachnoid hemorrhage. A cerebral angiogram showed dissecting aneurysm of right cerebral artery. ⋯ The patient underwent percutaneous tansluminalangioplasty coil and intraarterial injection of fasudil hydrochloride under local anesthesia. The consciousness recovered fully and the paralysis was improved. The patient delivered the baby by Caesarean sections under combined spinal and epidural anesthesia at 36 weeks without any problems with both the mother and baby.

There is an increasing number of patients scheduled for abdominal aortic aneurysm resection in whom epidural anesthesia cannot be performed because of concomitant antiplatelet/anticoagulant therapy. Instead of epidural anesthesia for postoperative analgesia in such patients it is possible to use repeated bilateral subcostal transversus abdominis plane (TAP) blocks. ⋯ These findings suggest that repeated bilateral subcostal TAP blocks with 0.2% lidocaine performed via 18-gauge intravenous catheters provide good postoperative analgesia after abdominal aortic aneurysm resection.
