Intraoperative awareness, a rare event affecting 0.1-0.2% of patients, can lead to psychological distress. Anesthesiologists should address patient recall to mitigate potential negative outcomes.

Area of Science:

  • Anesthesiology
  • Neuroscience
  • Patient Safety

Context:

  • Intraoperative awareness (IA) remains a concern in general anesthesia, with documented cases since its inception.
  • Published reports likely represent a fraction of actual IA events, as many patients do not report postoperative recall.
  • The incidence of IA with recall is estimated between 0.1% and 0.2%, with higher risks in specific patient populations.

Purpose:

  • To review the incidence, consequences, and management strategies for intraoperative awareness.
  • To evaluate the impact of implicit memory and psychological sequelae following IA.
  • To provide recommendations for preventing and managing IA and postoperative recall.

Summary:

  • IA can occur even without explicit memory, potentially leading to implicit memory and conditions like post-traumatic stress disorder.

  • Risk factors for IA include reduced anesthetic doses, hemodynamic instability, cesarean sections, and cardiac surgery.
  • Neuromuscular blockade should be used judiciously, and patients suspected of IA require specific communication and psychological support.

    • Impact:

    • Reconsidering the routine use of benzodiazepines for IA prevention is suggested.
    • Avoiding complete neuromuscular blockade can reduce IA risk.
    • Implementing postoperative inquiries about recall and providing psychological support can decrease severe sequelae.
