<unk>  under<unk> , also referred to as intraoperative<unk>  or accidental<unk>  during general<unk>  (AAGA), is a rare complication of general<unk>  where patients regain varying levels of consciousness during their surgical procedures. While<unk>  is possible without resulting in any long-term memory, the more clinically significant complication is<unk>  with explicit recall, where patients can remember the events related to their surgery (intraoperative<unk>  with explicit recall). Intraoperative<unk>  with explicit recall is an infrequent condition with potentially devastating psychological consequences. While it has gained popular recognition in media, research shows that it only occurs at an incidence rate of 0.1-0.2%. Patients report a variety of experiences ranging from vague, dreamlike states to being fully awake, immobilized, and in pain from the surgery. This is usually caused by the delivery of inadequate anesthetics relative to the patient's requirements. Risk factors for intraoperative<unk>  include anesthetic factors (i.e. use of neuromuscular blockade drugs, use of intravenous anesthetics, technical/mechanical errors), surgical factors (i.e. cardiac surgery, trauma/emergency, C-sections), and patient factors (i.e. reduced cardiovascular reserve, history of substance use, history of<unk>  under<unk> . Currently, the mechanism behind consciousness and memory as related to<unk>  is unknown, although there are many working hypotheses. However, intraoperative monitoring of anesthetic level with bispectral index (BIS) or end-tidal anesthetic concentration (ETAC) can help to reduce the incidence of intraoperative<unk> . There are also many preventative techniques considered for high-risk patients, such as pre-medicating with benzodiazepines, avoiding complete muscle paralysis, and managing patients' expectations. Diagnosis is made postoperatively by asking patients about potential<unk>  episodes and can be aided by the modified Brice interview questionnaire. A common but devastating complication of intraoperative<unk>  with recall is the development of post-traumatic stress disorder (PTSD) from the events experienced during surgery. Prompt diagnosis and referral to counseling and psychiatric treatment are crucial to the treatment of intraoperative<unk>  and the prevention of PTSD.
