We aimed to describe the ultrasound appearance of the radial nerve in the lateral aspect of the distal upper arm. This procedure was done to identify potential novel sites for ultrasound-guided radial-nerve block. ⋯ Points B and C may represent convenient, novel sites for ultrasound-guided radial-nerve block. The nerve is clearly visualized and has not yet divided into superficial and deep branches. Point C may be the optimal site for radial-nerve block because of the smaller risk of vessel puncture. Our observations also demonstrate the ability of ultrasound to identify nerves at sites not clearly defined by surface anatomic landmarks.

Ultrasound-guided and CT-navigation-assisted periradicular and facet joint injections in the lumbar and cervical spine: a new teaching tool to recognize the sonoanatomic pattern.
The aim of this study is to provide a teaching tool to facilitate the acquirement of periradicular and facet-joint infiltration techniques in the cervical and lumbar spine. ⋯ This teaching tool provides immediate CT-verification of sonographically identified structures and helps in the identification of bony landmarks, which are necessary for facet-joint and periradicular injections.

Randomized Controlled TrialA randomized controlled trial of the anticatabolic effect of epidural analgesia and hypocaloric glucose.
The goal of the present study was to investigate whether epidural analgesia exerts a protein-sparing effect after colorectal surgery in the presence of hypocaloric glucose supply initiated with surgical skin incision. ⋯ Epidural analgesia inhibits the increase in whole-body protein breakdown in patients receiving perioperative hypocaloric glucose infusion initiated with surgical skin incision. However, oxidative protein loss, protein synthesis, and glucose metabolism are not affected by epidural analgesia.
