The procedure for administering a spinal block involves several steps:
1. Positioning: The patient is usually positioned sitting up or lying on their side with their back curved. 2. Preparation: The injection site is cleaned and sterilized to reduce the risk of infection. 3. Insertion: A fine needle is inserted into the lower back to reach the subarachnoid space. 4. Injection: The local anesthetic is injected through the needle. 5. Monitoring: The patient's vital signs are closely monitored throughout the procedure.
