NeurologicalProcedure

 A Spinal Needles is a specialized, hollow-bore needle used to access the cerebrospinal fluid in the subarachnoid space for anesthesia, diagnosis, or therapy. Its design is critical: modern pencil-point tips (e.g., Whitacre) minimize the risk of post-dural puncture headache compared to older cutting bevels. Needle gauge (22G-27G) balances procedural ease with complication risk. Its use demands absolute aseptic technique, precise anatomical knowledge, and careful management of potentially life-threatening complications such as high spinal anesthesia or neurological injury. It is a fundamental, high-risk/high-reward tool in anesthesiology, neurology, and emergency medicine.
