Area of Science:

  • Robotic surgery
  • Neuroscience
  • Surgical education

Background:

  • Robot-assisted surgery demands high cognitive function.
  • Understanding surgeon's cognitive load is crucial for performance.
  • Expertise may alter cognitive resource allocation.

Purpose of the Study:

  • To investigate cognitive function in expert surgeons during robot-assisted surgery.
  • To correlate brain activity with performance metrics.
  • To analyze cognitive load during specific surgical tasks.

Main Methods:

  • Simultaneous use of electroencephalography (EEG) and NASA-Task Load Index (NASA-TLX).
  • Monitoring brain activity during lysis of adhesions, lymph node dissection, and urethro-vesical anastomosis (UVA).
  • Extraction of cognitive metrics: distraction, mental workload, and mental state.

Main Results:

  • Better performance linked to mental state and resource utilization.
  • Reduced distraction correlated with lower perceived demand.
  • Workload during UVA was primarily motor, relying on muscle memory.

Conclusions:

  • Expert surgeons dynamically adjust cognitive resource allocation based on task demands.
  • Cognitive function significantly impacts surgical outcomes.
  • Motor skills and muscle memory are critical for complex procedures like UVA.
