Abstract:
The authors pointed out that contamination may be exogenous, as a result of invasive diagnostic techniques, patient preparation, surgery, catheter insertion and wound dressing, or endogenous, especially in patients with specific risk factors (age, metabolic disorder, malnutrition, immunodeficiency) and aspecific risk factors (anesthesia, blood transfusion, surgery). Pharmacologic prophylaxis of infection may be unspecific (artificial nutrients, anticoagulants, immunomodulators) or specific (antibiotics). Prophylaxis is indicated in clean-contaminated and contaminated surgery; antibiotic chemoprophylaxis is also indicated in risk patients and permanent prosthesis surgery. The authors emphasized that antibiotics are no substitution for careful surgery.
Insights
Surgical site infections can arise from external sources or internal patient factors. Effective infection prevention involves appropriate prophylaxis, but careful surgical technique remains paramount.
Area of Science:
- Infectious Disease
- Surgical Science
- Pharmacology
Background:
- Surgical site infections (SSIs) pose a significant risk to patient outcomes.
- Infection sources can be exogenous (e.g., surgical procedures, devices) or endogenous (patient-specific risk factors).
- Existing literature highlights various risk factors contributing to SSIs.
Purpose of the Study:
- To delineate the sources of surgical contamination.
- To review current pharmacologic prophylaxis strategies for infections.
- To emphasize the importance of surgical technique in infection prevention.
Main Methods:
- Literature review of exogenous and endogenous contamination sources.
- Analysis of pharmacologic prophylaxis (non-specific and specific).
- Review of indications for prophylaxis in different surgical settings.
Main Results:
- Exogenous contamination stems from procedures and devices; endogenous factors include age, metabolic disorders, and immunodeficiency.
- Pharmacologic prophylaxis can be non-specific (nutrients, immunomodulators) or specific (antibiotics).
- Prophylaxis is recommended for clean-contaminated/contaminated surgery, high-risk patients, and permanent prosthesis implantation.
Conclusions:
- Antibiotic chemoprophylaxis is crucial in specific surgical contexts and for at-risk patients.
- Non-specific prophylaxis strategies also play a role in infection management.
- The study underscores that antibiotics cannot replace meticulous surgical practice for preventing infections.
