　Subarachnoidal anaesthesia, also known as spinal anesthesia or spinal anaesthesia, is the injection of an anesthetic into the subarachnoid space of the lumbar spine to numb the spinal nerve roots in that area. First the sympathetic fibers are blocked, then the sensory fibers, and finally the motor fibers. It is often used in lower abdominal and lower limb surgery. Common drugs are lidocaine, tetracaine and procaine. The diffusion of the drug through the spinal canal is affected by the patient's position, posture, dosage, injection force, and specific gravity of the solution. Procaine solution is usually more specific than cerebrospinal fluid. In order to control the diffusion of the drug, it is usually mixed into a solution of high or low specific gravity. If dissolved with released CEREBROspinal fluid or added to local anesthetics with 10% glucose solution, its specific gravity is higher than the cerebrospinal fluid, distilled water preparation of the specific gravity can be lower than the cerebrospinal fluid. A high specific gravity solution may diffuse to the lowest part of the dural space when the patient is in a sitting position or head position. Conversely, a low specific gravity solution is at risk of diffusion into the cranial space.
