Final answer:
The suitable spinal/epidural level for labor analgesia is the Lumbar level.
Step-by-step explanation:
The suitable spinal/epidural level for labor analgesia is the Lumbar level.
During labor, pain relief can be provided by injecting analgesic medication into the epidural space which surrounds the spinal cord. This is known as epidural anesthesia. In order to administer labor analgesia, a needle is inserted into the lower back and advanced until it reaches the lumbar region, specifically between the third and fourth or fourth and fifth lumbar vertebral level.
