Anesthesiology, anesthesia or anesthetics is the medical specialty concerned with the total perioperative care of patients before, during and after surgery. It encompasses anesthesia, intensive care medicine, critical emergency medicine, and pain medicine.
General anesthesia: The patient “goes to sleep” while the operation lasts.
Sedation: Intravenous drugs calm the patient or make them unaware of the procedure.
Regional anesthesia: Local anesthetic is injected near the nerves to numb the area that will be operated. These may be nerve blocks or spinal or epidural injections.
During the procedure, the surgeon carries out the surgical work, but the anesthesiologist will continue to be responsible for the medical management of the patient.
