The effect of Gunn's intramuscular stimulation for postherpetic neuralgia -A report of 4 cases-.
Herpes zoster is the consequence of reactivation of latent varicella zoster virus from dorsal root ganglia. Postherpetic neuralgia (PHN) may be diagnosed when pain persists in a dermatomal pattern long after the vesicular erruption has healed. PHN is a kind of neuropathic pain. ⋯ We tried Gunn's IMS for treatment of PHN patients affecting thoracic dermatomes. As a result, the visual analogue scale (VAS) was decreased from 7-8 to 2-3 and the result were satisfactory. The purpose of this case report is to introduce the Gunn's IMS and review our experience for the treatment of PHN.

A comparison of infraclavicular and supraclavicular approaches to the brachial plexus using neurostimulation.
A prospective, double blind study was performed to compare the clinical effect of vertical infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. ⋯ Both infraclavicular and supraclavicular brachial plexus block had similar effects. The infraclavicular approach may be preferred to the supraclavicular approach when considering the complications.

A complication of subclavian venous catheterization: extravascular kinking, knotting, and entrapment of the guidewire -A case report-.
Various complications of central venous catheterization have been reported, some of which are well-known, while others are described as a sporadic events. We experienced a case of left subclavian venous catheterization complicated by extravascular knotting, kinking, and entrapment of the guidewire and the guidewire was removed surgically. Although minimal resistance was encountered during guidewire insertion, the guidewire was advanced approximately 30 cm. Physicians should be aware of these rare potential complications when a guidewire is advanced if any resistance is encountered.

Cases series: ultrasound-guided supraclavicular block in 105 patients.
Multiple needle attempts to gain a muscle twitch or a paresthesia for a classical supraclavicular brachial plexus block can increase the risks of nerve damage or pain. The aims of this study were to obtain reliable clinical data on ultrasound-guided supraclavicular blocks, demonstrate the higher success rate and fewer complications, and design an injection method for patients whose brachial plexus can not be located. ⋯ An ultrasound-guided supraclavicular block is very effective in even patients whose brachial plexus can not be located.

The influence of age and gender on remifentanil EC(50) for preventing rocuronium induced withdrawal movements.
Rocuronium-induced withdrawal movements can be harmful to patients during the induction period. Remifentanil has been reported to reduce these movements effectively. In this study, we determined the EC(50) of remifentanil for the prevention of rocuronium induced withdrawal movements in male, female, old and child group. ⋯ The EC(50) of remifentanil for preventing rocuronium induced withdrawal movements was lowest in the elderly and higher in children than male adult patients. No difference in the EC(50) of remifentanil was seen between male and female adult patients.
