“What are the disadvantages of spinal anesthesia?”

There are some advantages of spinal anesthesia such as less blood loss, no need to have a breathing tube in the throat, less stress on the heart and lungs, and prolonged pain relief after the surgery if the anesthesiologist adds long-acting morphine to the mixture. A few disadvantages are postural spinal headaches, however, if a spinal anesthetic is done with a smaller Guage spinal needle, then chances are minimal.
