Definition

An anesthesiologist is trained to provide pain relief and maintenance, or restoration, of a stable condition during and immediately following an operation or an obstetric or diagnostic procedure. The anesthesiologist assesses the risk of the patient undergoing surgery and optimizes the patient's condition prior to, during and after surgery. In addition to these management responsibilities, the anesthesiologist provides medical management and consultation in pain management and critical care medicine. Anesthesiologists diagnose and treat acute, long-standing and cancer pain problems; diagnose and treat patients with critical illnesses or severe injuries; direct resuscitation in the care of patients with cardiac or respiratory emergencies, including the need for artificial ventilation; and supervise post-anesthesia recovery.

5/5

I had Dr. Pieterick as my anesthesiologist for LRTI surgery. He is very thorough in explaining what he will be doing, how he will manage any health concerns. He went over all my health conditions, listening patiently and answering all my questions. I felt very confident in his abilities and very comforted in going into the operating room. He did a fabulous job; I highly recommend him!
