Although the use of cuffed tracheal tubes (CTT) in children less than 8 years of age has increased, the criteria for selecting CTTs of appropriate sizes have not been determined. ⋯ We recommend the pediatric use of CTTs because of the very low tube-exchange ratio and the acceptable incidence of stridor. However, the protocol may require modification.

It is known that blood concentration of rocuronium increases after administration of sugammadex, but this is not clear in the case of vecuronium. We report a pediatric case in which serum vecuronium concentration increased following sugammadex administration after prolonged sedation using vecuronium. A 19-month-old girl weighing 7.8 kg had a history of aortic valvuloplasty at 4 months of age due to truncus arteriosus. ⋯ Recurarization might occur after sugammadex reversal in patients after long-term administration of vecuronium, especially if relatively smaller doses of sugammadex were given. We experienced a pediatric case in which serum vecuronium concentration increased following sugammadex administration after prolonged sedation using vecuronium. There is a risk of recurarization after sugammadex reversal in patients after long-term administration of vecuronium.

[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.
