Coronary arterial bypass operations without antibiotic coverage

Area of Science:

• Cardiovascular Surgery
• Infectious Disease Prevention
• Surgical Site Infections

Background:

• Surgical site infections (SSIs) are a concern in myocardial revascularization procedures.
• Prophylactic antibiotic strategies aim to minimize infection risk.

Purpose of the Study:

• To report the incidence of clean wound infection after myocardial revascularization without systemic antibiotics.
• To identify effective prevention methods for mediastinal wound infections in this patient group.

Main Methods:

• Retrospective analysis of 693 consecutive patients undergoing myocardial revascularization.
• Exclusion of patients receiving prophylactic systemic antibiotics.
• Documentation of clean wound infection rates and prevention strategies.

Main Results:

• Six infections (0.86%) occurred among 693 patients.
• This incidence is the lowest reported in the literature for this procedure.
• Preoperative skin preparation and local antibiotic wound irrigation were associated with prevention.

Conclusions:

• Myocardial revascularization can be performed with a very low infection rate without systemic antibiotics.
• Effective prevention relies on meticulous preoperative skin preparation and local antibiotic irrigation.
• Systemic antibiotic prophylaxis may not be necessary for preventing clean wound infections in these specific cases.
