Anesthesia is a medical treatment that prevents patients from feeling pain during surgery. It allows people to have procedures that lead to healthier and longer lives. During surgery, the physician anesthesiologist will monitor your vital signs to make sure they are normal and steady while you remain unconscious and free of pain. Once your surgery is complete, our physician anesthesiologist will reverse the medication and be with you as you return to consciousness, continually monitoring your breathing, circulation and oxygen levels.
