Enlarged Brachial Plexus Nerve Found During Ultrasound-Guided Peripheral Nerve Block Diagnosed as Charcot-Marie-Tooth Disease: A Case Report.

Ultrasound-guided peripheral nerve block (PNB) has become a popular anesthetic procedure. We report a case of an enlarged brachial plexus nerve noted on ultrasonographic images, as part of PNB, which was diagnosed postoperatively as Charcot-Marie-Tooth disease (CMTD), an inherited neurological disorder of the peripheral nerves. Although nerve enlargement is characteristic of demyelinating diseases such as CMTD, the use of ultrasonography in the diagnosis of neurological disorders is a developing area for neurologists and anesthesiologists can lack knowledge in this emerging field.

[Recovery from propofol anesthesia is delayed in hepatectomy patients due to altered pharmacodynamics].

Background: Liver dysfunction has major impacts on the pharmacokinetics and pharmacodynamics of anesthetics. This study was designed to evaluate propofol concentrations during and at the end of total intravenous anesthesia (TIVA) for hepatectomy.

Methods: Fifty patients receiving hepatectomy (n = 25) or other epigastric surgeries (controls, n = 25) were anesthetized with TIVA.

[Transient increase of bispectral index in a patient with bronchoconstriction after endotracheal intubation].

A 62-year-old woman (148 cm, 48.5 kg) with a history of bronchial asthma underwent an emergency appendectomy. Ten days before the operation she developed symptoms of wheezing while under asthma medication.
