Perioperative nerve injury and regional anaesthesia
Keywords:perioperative nerve injury, regional anaesthesia
Peripheral nerves consist of axons and dendrites which make up the parenchyma, as well as stroma consisting of connective tissue.1 The parenchyma is thus the conducting and neurologically functional element.2 Each axon is covered by an endoneurium. Axons are grouped together into fascicles which are surrounded by a perineurium. The perineurium forms a physical and chemical barrier and protects the peripheral nerve fascicles.2 Between the fascicles is stromal or connective tissue and blood vessels. The fascicles, connective tissue and blood vessels are held together into a unit by the epineurium.
