Spinal anaesthesia is a commonly used regional anaesthesia technique that temporarily numbs the lower part of the body during selected surgical procedures. It is administered by an anaesthesiologist through a small injection into the lower back, allowing the patient to remain awake or lightly sedated while the procedure is performed.
How Spinal Anaesthesia Works
The anaesthetic medicine is injected into the fluid surrounding the spinal nerves, temporarily blocking pain and sensation below the injection level. The anaesthesia team carefully monitors blood pressure, heart rate, oxygen levels, and overall comfort throughout the procedure.
When Is Spinal Anaesthesia Used?
Spinal anaesthesia may be considered for certain procedures involving the lower abdomen, pelvis, hips, and legs. The appropriate type of anaesthesia depends on the surgical procedure, medical history, medications, allergies, and the anaesthesiologist's assessment.
Benefits and Recovery
Potential benefits include effective pain control during surgery, reduced awareness of surgical pain, and avoidance of general anaesthesia in suitable patients. Temporary numbness or weakness in the legs is expected and gradually wears off as the anaesthetic effect decreases.
Before surgery, patients may be advised about fasting, medications, and other preparation requirements. After the procedure, the medical team monitors recovery and provides guidance on movement, eating, drinking, and discharge.
