A spinal block is a medical procedure used to provide anesthesia by injecting medication into the spinal canal. This technique numbs the lower part of the body, making it useful for surgeries such as cesarean sections or orthopedic procedures. The medication works by blocking nerve signals, allowing patients to remain awake and pain-free during the operation. The procedure is typically performed by an anesthesiologist, who carefully administers the anesthetic near the spinal cord. While generally safe, potential risks include headaches, infection, or nerve damage. Patients are monitored closely to ensure a smooth recovery after the procedure.
