Abstract: | Awareness during general anesthesia occurs when patients recall events or sensations during their surgeries, although the
patients should have been unconscious at the time. Anesthesiologists are cognizant of this phenomenon, but few discussions
occur outside the discipline. This narrative review summarizes the patient recollections, psychological sequelae, treatment
and follow-up of psychological consequences, as well as incidence and etiology of awareness during general anesthesia. Recalled
memories include noises, conversations, images, mental processes, feelings of pain and/or paralysis. Psychological consequences
include anxiety, flashbacks, and posttraumatic stress disorder diagnosis. Limited discussion for therapeutic treatment after
an anesthesia awareness experience exists. The incidence of anesthesia awareness ranges from 0.1 to 0.2% (e.g., 1–2/1000 patients).
Increased recognition of awareness during general anesthesia within the psychological/counseling community, with additional
research focusing on optimal therapeutic treatment, will improve the care of these patients. |
