The axillary brachial plexus block is a very safe, but sometimes unreliable technique for anaesthesia of the upper extremities. Alternative methods like the infraclavicular block offer a higher success rate, but also the possibility of severe complications. We suggest a modified axillary technique with an injection site medial to the artery, evaluated by clinical experience and anatomical investigations, which could solve the problem of high failure rate, especially in the area of the radial nerve while still maintaining patient safety.

To achieve profound dental local anesthesia, it is necessary for the dentist to have a thorough knowledge of the details of sensory innervation to the maxilla and mandible. Since the early 1970s, dentistry has experienced a resurgence of interest in the neuroanatomical basis of local anesthesia, resulting in numerous scientific reports on the subject. ⋯ An understanding of the potential variations in innervation should help the dentist improve his or her ability to induce profound local anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of the parasacral approach and the posterior approach, with single- and double-injection techniques, to block the sciatic nerve.
The purpose of this study was to compare parasacral and Winnie's single- or double-injection approaches for sciatic nerve block. ⋯ Time to perform a parasacral block was short, and the parasacral approach had a high success rate and a short onset time. Therefore, this block might be a useful alternative to Winnie's modification for sciatic nerve block.
