[Antibiotic prophylaxis and reconstructive operations in patients with burn sequelae]
Summary
Antibiotic prophylaxis is recommended for reconstructive surgery on burn scars, particularly for high-risk patients. Cefazolin and carbenicillin show good penetration and efficacy against scar microflora, reducing infection risk.
Area of Science:
- Plastic surgery
- Infectious disease
- Pharmacology
Context:
- Reconstructive operations for postburn scars carry a risk of infection.
- Microflora, primarily Staphylococcus aureus and S. epidermidis, is present in approximately half of postburn scars.
- Ulcerated scars exhibit higher bacterial contamination levels.
Purpose:
- To evaluate the efficacy of antibiotic prophylaxis in patients undergoing reconstructive surgery for postburn scars.
- To assess the penetration and activity of cefazolin, carbenicillin, aztreonam, and gentamicin in scar tissues.
- To identify risk factors associated with purulent inflammatory complications.
Summary:
- Clinicolaboratory investigation of 215 patients undergoing reconstructive surgery for postburn scars.
- Biological investigation revealed microflora in half of the patients, mainly Staphylococcus aureus and S. epidermidis, with higher contamination in ulcerated scars.
- Pharmacokinetic studies showed good tissue release for cefazolin, carbenicillin, and aztreonam.
- Clinical observations indicated purulent inflammatory complications in high-risk patients not treated with effective antibiotics.
- Antibiotic prophylaxis is recommended for high-risk patients, with cefazolin and carbenicillin advised due to their penetration and activity against scar microflora.
Impact:
- Recommends targeted antibiotic prophylaxis for reconstructive surgery in high-risk burn scar patients.
- Identifies cefazolin and carbenicillin as effective agents for preventing post-operative infections in this population.
- Highlights the importance of considering scar characteristics and patient risk factors in antibiotic selection.
