What is post-operative care for someone who had spinal anesthesia?

Follow instructions: We used to tell patients to lie flat for 6 hours after spinal anesthesia, but now we know that doesn't help prevent a headache. You may resume activity according to the surgeon's instructions, depending on what type of surgery you had. No need to lie flat; just rest when you feel tired, and lie in whatever position is most comfortable for you. Drink plenty of liquids.
