Patient-controlled intravenous diazepam effectively reduced preoperative anxiety in a study of 50 patients. This self-administered anxiolysis proved valuable for managing patient anxiety before surgery.

Area of Science:

  • Anesthesiology
  • Psychopharmacology
  • Patient Safety

Background:

  • Preoperative anxiety significantly impacts patient experience and recovery.
  • Current premedication strategies may not adequately address individual patient anxiety levels.
  • Exploring patient-controlled methods for anxiolysis offers potential for personalized care.

Purpose of the Study:

  • To assess the feasibility and efficacy of self-premedication with intravenous diazepam using patient-controlled analgesia (PCA) devices.
  • To determine the relationship between patient-reported anxiety and administered diazepam dose.
  • To evaluate the safety and effectiveness of patient-administered anxiolysis in a preoperative setting.

Main Methods:

  • An open study involving 50 preoperative patients utilizing a PCA system for diazepam self-administration.

  • Patients received 2 mg aliquots of diazepam on demand, up to a maximum of 20 mg over 30 minutes.
  • Anxiety levels were assessed by both patients and anesthesiologists before and after premedication.

    • Main Results:

    • A mean dose of 8.1 mg of diazepam was administered, significantly reducing anxiety ratings for both patients and anesthesiologists.
    • Patient's own preoperative anxiety level was a poor predictor of self-administered dose; anesthesiologist's assessment did not correlate.
    • No instances of excessive sedation were reported, indicating a favorable safety profile.

    Conclusions:

    • Self-premedication with intravenous diazepam via PCA is a feasible and effective method for reducing preoperative anxiety.
    • Patient-administered anxiolysis can be a valuable tool for managing anxiety, particularly in patients with high preoperative anxiety levels.
    • This approach offers a promising avenue for further research into anxiety management and personalized patient care.
