Anesthesia is only given to patients who undergo surgery to relieve pain or to put these patients to sleep for the duration of the surgery. An anaesthesiologist provides care to their patient before, during and after a surgery.

An anesthesiologist monitors a patients’ vital functions like the heart rate, breathing and blood pressure and regulates anesthesia at all times of the surgery to ensure it maintains at the same level as before the surgery. If there are any medical problems that arise during surgery, anesthesiologists are the ones that immediately respond, diagnose and treat it.
