Cold dissection versus bipolar cauterizing tonsillectomy for bacteriemia.

Area of Science:

• Otolaryngology
• Surgical Infection Control
• Microbiology

Background:

• Tonsillectomy is a common surgical procedure.
• Transient bacteriemia can occur post-tonsillectomy, posing infection risks.
• Different tonsillectomy techniques may influence bacteriemia rates.

Purpose of the Study:

• To compare the incidence of transient bacteriemia between cold dissection tonsillectomy and bipolar cauterizing tonsillectomy.
• To identify and analyze bacteria present in tonsillar cultures.
• To evaluate the clinical implications of bacteriemia in tonsillectomy patients.

Main Methods:

• A comparative study involving 86 patients undergoing tonsillectomy (46 cold dissection, 40 bipolar cauterization).
• Collection of preoperative surface swabs, intraoperative central tonsil swabs, and blood cultures (pre- and post-operative).
• Statistical analysis using Fischer exact chi-squared test to compare bacteriemia rates.

Main Results:

• Postoperative bacteriemia occurred in 13% of the cold dissection group, with microorganisms identified in blood and tonsil cultures.
• Penicillin resistance was noted in isolated microorganisms from the cold dissection group.
• No postoperative bacteriemia was observed in the bipolar cauterizing tonsillectomy group (P=.028).

Conclusions:

• Bipolar cauterizing tonsillectomy demonstrates a significantly lower rate of postoperative bacteriemia.
• The technique appears safer in terms of reducing bloodstream infections post-procedure.
• Bipolar cauterizing tonsillectomy is recommended for patients considered high-risk for surgical site infections.
