Questions and Answers

What are the main factors influencing the choice of anesthesia for Endoscopic Sinus Surgery?

  • Extent of surgery, patient factors, and anesthesiologist's expertise (correct)
  • Surgical field visualization, hemodynamic response, and blood pressure
  • Surgeon experience, patient cooperation, and recovery time
  • Preoperative steroids, navigation systems, and anesthesia type

    • What are the pros of using Local Anesthesia with Sedation for ESS?

  • Provides airway control, ideal for long procedures
  • Reduces hemodynamic response compared to intubation
  • Shorter operative and recovery times, less nausea and vomiting (correct)
  • May improve surgical field visualization compared to inhalational anesthesia

    • What is a specific use of Laryngeal Mask Airway (LMA) in ESS?

  • May improve surgical field visualization
  • Shortens recovery time and reduces complications
  • Ideal for anxious patients or those using navigation systems
  • Reduces hemodynamic response compared to endotracheal intubation (correct)

    • Which technique can help lower blood pressure without affecting blood flow during ESS?
