A small percentage of patients (0.1-0.2%) experience awareness during general anesthesia, which can lead to significant psychological distress, including anxiety and posttraumatic stress symptoms.

Area of Science:

  • Anesthesiology
  • Psychology

Background:

  • Intraoperative awareness during general anesthesia affects a small but significant patient group.
  • Awareness can lead to adverse psychological outcomes, including anxiety and posttraumatic stress symptoms.

Purpose of the Study:

  • To summarize the incidence and consequences of intraoperative awareness.
  • To discuss the potential for developing anxiety and posttraumatic stress symptoms post-awareness.

Main Methods:

  • Review of existing literature on intraoperative awareness.
  • Analysis of retrospective studies on patient experiences.

Main Results:

  • 0.1% to 0.2% of patients undergoing general anesthesia report awareness.
  • Some patients experience pain and/or anxiety during awareness.

  • Risk of developing persistent anxiety and posttraumatic stress symptoms exists.
  • Conclusions:

    • Intraoperative awareness is a rare but serious complication of general anesthesia.
    • Psychological sequelae, including anxiety and PTSD, are significant concerns.
    • Retrospective study designs necessitate caution regarding reported incidence and severity.
