Caffeine intake may negatively impact microsurgical skill, particularly for novice surgeons. This study found improved performance when caffeine was consumed in the morning, suggesting a detrimental effect when taken later.

Area of Science:

  • Microsurgery
  • Surgical Skill Assessment
  • Pharmacology

Background:

  • Microsurgeons often avoid caffeine due to concerns about tremor.
  • Empirical evidence demonstrating caffeine's adverse effects on surgical skills is lacking.
  • Understanding caffeine's impact is crucial for optimizing surgical performance.

Purpose of the Study:

  • To investigate the effect of moderate caffeine intake on microsurgical ability.
  • To determine if caffeine consumption influences performance in microsurgical tasks.
  • To evaluate the relationship between caffeine timing and microsurgical skill.

Main Methods:

  • Double-blind, placebo-controlled, crossover study design.
  • Participants were randomized to receive caffeine or placebo in the morning/afternoon.

  • Microsurgical skill assessed via end-to-end vessel anastomosis and global rating scale.

    • Main Results:

    • Subjects showed improved microsurgical scores from morning to afternoon when caffeine was consumed in the morning.
    • No significant improvement was observed when caffeine was consumed in the afternoon.
    • Results suggest a detrimental effect of caffeine on microsurgical ability in novice surgeons.

    Conclusions:

    • Caffeine may have a detrimental effect on microsurgical ability, especially in novice surgeons.
    • The timing of caffeine intake appears to influence its impact on surgical performance.
    • Findings support the avoidance of caffeine by microsurgeons to prevent potential skill impairment.
