Spinal anesthesia is a regional anesthesia technique used to numb the lower part of the body during certain surgical procedures. A small dose of local anesthetic is injected into the fluid surrounding the spinal cord in the lower back. This temporarily blocks pain and sensation, while you may remain awake or receive mild sedation.
When Is Spinal Anesthesia Used?
Spinal anesthesia is commonly considered for surgeries below the waist, including selected orthopedic, urological, gynecological, vascular, and general surgical procedures. Your anesthesiologist will assess your medical history, medications, planned surgery, and overall health before recommending the most appropriate anesthesia.
Benefits of Spinal Anesthesia
Depending on your procedure and individual health, potential benefits may include effective pain control during surgery, less nausea and vomiting, reduced need for strong pain medicines, and an earlier return to eating and drinking. It may also have less impact on breathing than general anesthesia.
Procedure and Recovery
Before the procedure, your anesthesiologist will explain the process and provide instructions about fasting and medications. After the injection, your legs may feel warm, numb, or heavy for several hours. You will be monitored until sensation and movement return safely. Temporary low blood pressure, difficulty passing urine, itching, or headache can occur. Serious complications such as nerve injury are rare.
