Summary

Disposable bipolar diathermy increases surgeon eye contamination risk during tonsillectomy compared to reusable monopolar diathermy. This finding is crucial for surgical safety protocols in ENT procedures.

Area of Science:

  • Otolaryngology
  • Surgical Safety
  • Ophthalmology

Background:

  • Tonsillectomy is a common surgical procedure.
  • Surgeon eye contamination is a potential risk during tonsillectomy.
  • Different diathermy devices may pose varying risks.

Purpose of the Study:

  • To compare the risk of conjunctival contamination for surgeons using disposable bipolar diathermy versus reusable monopolar diathermy during tonsillectomy.
  • To evaluate the efficacy of protective eyewear in preventing contamination.

Main Methods:

  • Prospective, single-blind, randomized controlled trial.
  • 168 patients undergoing elective tonsillectomy.
  • Surgeons wore protective eyewear, later examined for blood spots.

Main Results:

  • Disposable bipolar diathermy was associated with a 2.8 times higher relative risk of conjunctival contamination compared to reusable monopolar diathermy (p < 0.0005).
  • History of peritonsillar abscess and concurrent adenoidectomy increased blood splatter.
  • The protective eyewear was examined for blood spots.

Conclusions:

  • Disposable bipolar diathermy presents a significantly greater risk of conjunctival contamination for surgeons during tonsillectomy.
  • Reusable monopolar diathermy appears safer regarding surgeon ocular exposure.
  • Findings emphasize the need for enhanced safety measures when using disposable bipolar diathermy.
