M R Keighley, M Gannon, J Warlow

    British Medical Journal
    |September 27, 1980
    PubMed
    Summary

    Pre-operative hypnotics like triazolam and flurazepam significantly improve patient sleep before surgery. Triazolam demonstrated superior benefits over flurazepam in enhancing sleep quality and reducing awakenings.

    Area of Science:

    • Anesthesiology
    • Pharmacology
    • Sleep Medicine

    Background:

    • Pre-operative anxiety and sleep disturbances are common in patients undergoing elective surgery.
    • Poor sleep quality can negatively impact patient recovery and surgical outcomes.
    • The efficacy of short-term hypnotic use for improving pre-operative sleep is an area of interest.

    Purpose of the Study:

    • To evaluate the effectiveness of a single dose of triazolam, flurazepam, or placebo on sleep quality before elective surgery.
    • To compare the effects of triazolam and flurazepam in improving sleep onset, duration, and reducing awakenings.

    Main Methods:

    • Prospective, randomized, double-blind, controlled trial involving 96 patients.
    • Administration of a single dose of triazolam, flurazepam, or placebo on the night before surgery.

  • Sleep parameters (onset, duration, awakenings) were assessed using patient and nurse questionnaires.

    • Main Results:

    • Placebo significantly disrupted sleep, delaying onset and reducing duration in two-thirds of patients.
    • Both triazolam and flurazepam significantly improved sleep onset, duration, and reduced awakenings compared to placebo.
    • Triazolam showed a faster sleep onset and fewer awakenings than flurazepam, with additional pre-operative advantages noted.

    Conclusions:

    • A single pre-operative dose of a hypnotic agent effectively improves sleep for patients undergoing elective surgery.
    • Triazolam appears to offer greater benefits in sleep enhancement compared to flurazepam for the pre-operative period.
    • Hypnotic administration the night before surgery can positively impact patient sleep and potentially perioperative well-being.
