Case Reports
[The efficacy of ultrasound-guided infraorbital nerve block with hockey stick typed probe].
We report a case of ultrasound-guided infraorbital nerve block with a hockey stick typed probe in plane approach. Individual difference of infraorbital anatomy makes it difficult to puncture the infraorbital for a man, and the risks include bleeding, double vision and paranasal sinus puncture. ⋯ Compared with conventional land mark method approach, ultrasound technique is thought to be easy to perform, more quickly and safely without any complications. From our results, we have demonstrated that ultrasound-guided infraorbital nerve block assisted by hockey stick typed probe could become one of the safe methods for this purpose.

In an animal model, neonatal exposure to sevoflurane induces neuroapoptosis, leading to memory deficits in adulthood. A recent study showed that resveratrol (20 mg x kg(-1)) prevent alcohol-induced cognitive deficits and neural apotosis in rat pups postnatally exposed to ethanol. We investigated if resveratorol prevent sevoflurane induced neuroapotosis. ⋯ Resveratrol did not prevent sevoflurane-induced neuroapoptosis in the neonatal mice brain.

A 63-year-man with lung cancer underwent right upper lobectomy under general anesthesia combined with thoracic epidural anesthesia. The surgical course was uneventfully completed. On the second postoperative day, he developed complete paralysis below T4 level 1 hour after removal of the epidural catheter. ⋯ Surgical removal of hematoma was scheduled. However, his neurological condition improved rapidly within a couple of hours, and the surgery was not carried out. The time course of recovery from complete paralysis suggests that extradural hematoma diffused into the extradural space, resulting in a decrease in the epidural pressure.

Case Reports
[A case of rocuronium-induced anaphylactic shock successfully treated with sugammadex].
We report a case of a 19-year-old male with rocuronium-induced anaphylactic shock. He was scheduled for endoscopic sinus surgery for chronic sinusitis under general anesthesia. Induction of anesthesia was done with fentanyl, propofol and sevoflurane. ⋯ The plasma beta-tryptase increased to 46 microg x l(-1) during the shock state and returned to 14.1 microg x l(-1) 8 hrs after the event. The blood hemoglobin level also increased to 21.3 g x dl(-1) during the shock state and returned to 17.2 g x dl(-1) during the recovery phase. The laboratory data showed a marked increase in vascular permeability caused by rocuronium-induced anaphylactic shock.

Randomized Controlled Trial Comparative Study
[Comparison of the efficacy of ropivacaine and that of levobupivacaine for postoperative epidural analgesia in patients undergoing gynecological open abdominal surgery].
Postoperative analgesia is important in patients undergoing open abdominal surgery. We prospectively compared the efficacy of ropivacaine and that of levobupivacaine for postoperative epidural analgesia in patients undergoing gynecological open abdominal surgery. ⋯ Both 0.187% ropivacaine and levobupivacaine similarly provide appropriate postoperative epidural analgesia for patients undergoing gynecological open abdominal surgery.
