Antimicrobial prophylaxis in minor and major surgery

Area of Science:

• Infectious Diseases
• Surgical Sciences
• Pharmacology

Background:

• Surgical site infections (SSIs) are a common cause of patient morbidity after surgery.
• Gram-positive and Gram-negative bacteria are the primary pathogens responsible for SSIs.
• Patient and procedure-related factors influence SSI risk.

Purpose of the Study:

• To review antimicrobial prophylaxis (AP) strategies for reducing SSIs.
• To highlight key components of effective AP: timing, drug choice, duration, and cost.
• To provide guidance on appropriate AP regimens for various surgical procedures.

Main Methods:

• Review of existing literature on antimicrobial prophylaxis for SSIs.
• Analysis of factors influencing SSI development and prevention.
• Examination of recommended practices for AP administration, including timing and duration.

Main Results:

• Antimicrobial prophylaxis is effective in reducing SSIs, particularly when risk factors are present.
• Ideal AP administration starts within 30 minutes of incision and generally does not exceed 24 hours.
• Single-dose regimens are as effective as multiple doses, and post-surgical administration is unnecessary.
• Broad-spectrum antibiotics should be avoided to prevent resistance; cephalosporins like cefazolin/cefuroxime are common choices.

Conclusions:

• Adherence to established AP principles can significantly decrease SSI incidence.
• Appropriate selection and administration of prophylactic antibiotics are vital for patient safety and outcomes.
• Specific AP regimens, often involving cephalosporins, are recommended for various surgical specialties.
