Randomized Controlled Trial
[Optimal analgesic effect of continuous supraclavicular brachial plexus block with ropivacaine after shoulder surgery].
Optimal dose of local anesthetics for supraclavicular brachial plexus block (BPB) is still unknown. We prospectively investigated the analgesic effect of ultrasound-guided continuous supraclavicular BPB with ropivacaine at different infusion rates. ⋯ Continuous supraclavicular BPB with 0.2% ropivacaine at 6 ml x hr(-1) is effective for the pain management after shoulder surgery and is not an excess dose.

The i-gel (Intersurgical Ltd., Wokingham, Berkshire, UK) is a new single-use noninflatable supraglottic airway device. It is composed of a soft, gel-like, transparent, thermoplastic elastomer, which provides a perilaryngeal seal without cuff inflation. In this case report, we describe the airway management using i-gel in two patients scheduled for awake craniotomy. ⋯ The i-gel was reinserted before the closure of the dura without difficulties despite the fact that necks were rotated about 30 degrees rightward, and remained in place until the end of surgery. All procedures finished uneventfully and without adverse events. We conclude that i-gel is effective in asleep-awake-asleep technique because of its easiness in reinsertion under condition of rotated neck.

Varicella-zoster virus (VZV) causes two clinically distinct diseases: varicella and herpes zoster. Herpes zoster, recurrent infection of VZV occurs when the cell-mediated immunity to VZV declines. Since the cell-medicated immunity to VZV declines with aging, herpes zoster occurs more frequently in the elderly. ⋯ They rather aggravate PHN with time. Recent research with a live attenuated varicella vaccine to prevent herpes zoster indicated that the vaccine decreased the occurrence of herpes zoster and postherpetic neuralgia by almost half as compared with placebo. Vaccination of high risk subjects with the varicella vaccine seems to be the most effective measure for the prevention of postherpetic neuralgia.

To prevent peripheral nerve injury and neuropathic pain resulting from venipuncture, medical students and medical workers should be educated about the following points in clinical practice. First, the medial aspect of the antecubital fossa should not be punctured, to prevent injury to the median and medial anterobrachial cutaneous nerves. Second, the symptoms and signs of neuropathic pain resulting from venipuncture should be taught, to recognize the onset of neuropathic pain. Third, pharmacotherapy for the management of neuropathic pain should be taught to treat neuropathic pain resulting from venipuncture.
