Anesthesia Awareness During Surgery

In extremely rare cases, a patient can become conscious during surgery and subsequently recall what occurred. This experience, referred to as “intraoperative awareness,” or anesthesia awareness, is estimated to occur about 1 to 2 times per every 1,000 uses of general anesthesia. Most patients do not experience any pain due to intraoperative awareness, but it can be disturbing and some patients may need counseling following surgery to ease their anxiety.

Founded in 1905, the American Society of Anesthesiologists (ASA) is an educational, research and scientific society with more than 52,000 members organized to raise and maintain the standards of the medical practice of anesthesiology. ASA is committed to ensuring physician anesthesiologists evaluate and supervise the medical care of patients before, during and after surgery to provide the highest quality and safest care every patient deserves.
