What is the difference between epidural anesthesia and spinal anesthesia?

The difference between epidural anesthesia and spinal anesthesia is as follows: 1. Epidural anesthesia and spinal anesthesia are both half-body anesthesia. The biggest difference between them is that the site of injection of local anesthesia is different. There are many layers from the spinal canal to the spinal cord. The outermost layer is called the epidural space, which is between the spinal canal and the dura mater. Epidural anesthesia is to be injected into the epidural space. 2. There is also a big difference in the amount of anesthetic injected. The local anesthetic used in epidural anesthesia is several times to 10 times that of spinal anesthesia. Generally, the onset time of spinal anesthesia will be faster and the effect will be more perfect, but the probability of hypotension may be higher than that of epidural anesthesia. 3. Spinal anesthesia is generally limited to the waist, and the epidural can reach a higher position, mainly for operations on the lower abdomen and lower limbs. 4, epidural anesthesia can do some pain in the chest.
