Glass Spine Demonstration Spread of Local Anesthetic in the Subarachnoid space. Influence of baricity and Postures

Description

Glass spine is a glass tube curved in the same way as the vertebral column, dural sac and subarachnoid space. The vertebral column curves along with gravity, baricity, patient position, influence the spread of local anesthetics in the subarachnoid space. Lidocaine, tetracaine and bupivacaine are most commonly used local anesthetic agents for spinal anesthesia. Spread of local anesthesia with cerebrospinal fluid determines the extent of altered neuronal function. This video demonstrates in detail about the hyperbaric, isobaric spread of local anesthesia using glass spine instrument.
