Case Reports[Multitruncular block at the elbow for a major hand trauma for prehospital care].
Upper limb peripheral nerve blocks offer many advantages but they are not widely used in prehospital care. We report the case of a multitroncular block at the elbow made by the emergency department team out of the hospital after a major hand trauma. A successful axillary brachial plexus block was done two hours later, without any problem. This case report allows us to discuss about different analgesia techniques useful in prehospital care.

Most local anaesthetic blocks are placed blindly, based on a sound knowledge of anatomy. Very often the relationship between the site of deposition of local anaesthetic and the nerve to be blocked is unknown. Large motor neurons may be stimulated with the aid of an electrical current. ⋯ The accuracy of local anaesthetic blocks can be improved by this technique. By using the lowest possible current a needle could be positioned with in 2-5 mm of a nerve. The correct duration of stimulation ensures that stimulation of sensory nerves does not occur The use of electrical nerve stimulation in veterinary medicine is a novel technique that requires further evaluation.

ReviewTension pneumothorax: a pulmonary complication secondary to regional anesthesia from brachial plexus interscalene nerve block.
Interscalene brachial plexus anesthesia is often used for surgeries involving the shoulder and upper arm. This method of regional anesthesia decreases pain, nausea, and vomiting associated with general anesthesia. ⋯ Recognition of early signs and symptoms of tension pneumothorax and expeditious treatment for rapid decompression before physiologic decompensation is mandatory. This article discusses the interscalene brachial plexus block procedure leading to the pathogenesis, clinical presentation, diagnosis, and treatment of tension pneumothorax.
