At the time of the operation, the surgeon will have already discussed with the patient the type of anesthesia that is expected to be used in his intervention. Depending on this and each patient, it can be:
✓ Local anesthesia: only the area where the incision will be made is anesthetized.
✓ Regional anesthesia: epidural or spinal anesthesia, the lower half of the body is anesthetized, approximately from the waist down.
✓ General anesthesia: the patient falls asleep completely, and it is usually necessary to maintain breathing through endotracheal intubation and mechanical ventilation.
