The peripheral nerve blockade is central to “Fast Track Surgery” which aims to facilitate an early discharge from the hospital and more rapid resumption of normal activities of daily living after surgery. The anatomical basis for the peripheral nerve blockade is one that conceives of the nerves to be enclosed by a tubular fascia sheath into which local anaesthetic solution is injected. The nerve fascial sheath has three layers called endoneurium, perineurium and epineurium. The precise nature and architecture of these fascial layers remain unclear. For instance, it is generally believed that perineurium extends from the meninges and serves as the blood-nerve barrier to protect the axons from mechanical and chemical attacks. However, our recent findings indicate that both arachnoid and dura maters do not extend beyond the skull base in the human1-3. The aim of this project is to identify and map the nature and configuration of the fascial coverings of the peripheral nerve using a combination of microdissection, histology, immunohistochemistry, epoxy sheet plastination, and confocal microscopy. The results may provide new perspective for a precise needle tip placement for successful peripheral nerve blockade and understanding of mechanisms for periphery nerve protection.
