Spinal Anesthesia is a medical procedure used to provide pain relief during surgeries, particularly in the lower body. It involves injecting a local anesthetic into the spinal canal, which numbs the nerves that control sensation and movement in the lower half of the body. This technique is commonly used for procedures like cesarean sections and knee surgeries. The procedure is typically performed in a hospital setting by an anesthesiologist or nurse anesthetist. Patients are usually awake during the surgery but do not feel pain. Spinal Anesthesia is considered safe, but like any medical procedure, it carries some risks, including headaches or infection.
