Modafinil (200 mg) significantly reduced fatigue and improved alertness in patients recovering from general anesthesia. This wakefulness-promoting drug offers substantial benefits for postoperative recovery, enhancing energy levels and reducing exhaustion.

Area of Science:

  • Anesthesiology
  • Pharmacology
  • Postoperative Care

Background:

  • General anesthesia recovery is often complicated by prolonged sedation, drowsiness, and fatigue.
  • Modafinil is an FDA-approved wakefulness-promoting agent for narcolepsy-related daytime sleepiness.

Purpose of the Study:

  • To evaluate the efficacy of a single 200 mg dose of modafinil in mitigating postoperative fatigue and improving recovery from general anesthesia.
  • To assess the impact of modafinil on patient-reported outcomes of alertness and energy levels post-discharge.

Main Methods:

  • Prospective, randomized, double-blind, placebo-controlled study involving 34 subjects recovering from general anesthesia.
  • Patients received either modafinil (200 mg) or placebo postoperatively after meeting discharge criteria.

  • Symptom severity (fatigue, exhaustion) and overall feelings of alertness and energy were assessed using verbal analog scales (VAS) 24 hours post-dosing.

    • Main Results:

    • Patients receiving modafinil reported significantly less postoperative fatigue (1.4 vs. 4.8 on VAS), exhaustion (2.4 vs. 4.3), and feeling worn out (2.9 vs. 4.7) compared to placebo.
    • A significantly lower percentage of modafinil recipients experienced moderate to severe fatigue (12% vs. 65%).
    • Improved "alertness" and "energy" were reported by 71% of modafinil patients versus 18% of placebo patients.

    Conclusions:

    • Single-dose modafinil administration significantly alleviates fatigue and enhances feelings of alertness and energy in patients recovering from general anesthesia.
    • Modafinil represents a beneficial therapeutic option for improving the quality of recovery and reducing residual sedation effects post-anesthesia.
