Controlling mental tension during sinonasal surgery is crucial for managing hypertension and reducing bleeding. Effective sedation and anesthesia techniques can limit blood loss to under 10 ml in most patients.

Area of Science:

  • Otolaryngology
  • Surgical Oncology
  • Anesthesiology

Context:

  • Sinonasal surgeries, including ethmoidectomy and polyp removal, can be associated with significant intraoperative bleeding.
  • Hypertension, often exacerbated by mental tension during surgery, is a key factor influencing blood loss.
  • Previous operations and specific anatomical types (e.g., Type III) may present unique challenges for bleeding control.

Purpose:

  • To investigate the impact of mental tension and blood pressure control on bleeding during sinonasal surgery.
  • To evaluate the effectiveness of sedation, topical anesthesia, and reduced operative time in minimizing blood loss.
  • To compare bleeding amounts in hypertensive patients with and without controlled blood pressure.

Summary:

  • A study of 82 patients undergoing sinonasal surgery found that mental tension can induce hypertension and increase bleeding.

Related Experiment Videos

  • Controlling blood pressure and reducing operative time were associated with significantly less blood loss.
  • The study demonstrated that 69% of patients had bleeding limited to 10 ml with appropriate anesthetic and surgical techniques.

    • Impact:

    • Findings highlight the importance of managing patient anxiety and blood pressure for safer sinonasal procedures.
    • The study provides evidence for optimizing anesthetic and surgical strategies to minimize complications like excessive bleeding.
    • Successful bleeding control contributes to improved patient outcomes, with 72% of patients cured and 22% improved after 6 months.
