Perioperative period

The perioperative period is a period of a patient's surgical procedure. The period may include the three phases of surgery (preoperative, intraoperative, and postoperative), though it is a term most often used for the first and third of these only. It commonly includes ward admission, anesthesia, surgery, and recovery. Perioperative care is the care that is given before and after surgery. The primary concern of perioperative care is to provide better conditions for patients before an operation (sometimes construed as during operation) and after an operation.
