The branch of medicine that is focused on the relief of pain in the perioperative period (i.e. before, during or after a surgical procedure) is known as anesthesiology. The medicaments administered are termed anesthesia and the doctor who is trained in this specialty is referred to as an anesthesiologist

Study looks at intraoperative awareness

In some cases a patient might lie on the operating table conscious and aware of the surgeon's knife despite general anesthesia and this is worrisome say experts.
