Effect of Paraesthesia in Spinal Anaesthesia into the cerebrospinal fluid

Wang Nicholas

Small amounts of local anaesthetic are injected into the cerebrospinal fluid (CSF) to cause spinal anaesthesia. This solution needs to be able to block nerve pathways and be non-toxic, meaning it shouldn't impair the bulbar centres' ability to function or affect the metabolism of the more vital organs. Typically, the injection is performed in the lumbar spine below the point where the spinal cord terminates (L2). Recent magnetic resonance imaging (RMI) studies on 19 and 50 individuals' thoracic spinal architecture have shown the safety of segmental spinal anaesthesia at T10 when performed using either the combined spinal-epidural method or single puncture.
