Insights
Anaerobic bacteria are increasingly recognized in pediatric infections, particularly in post-surgical wounds (PSW). Wound flora often correlates with nearby mucous membranes, guiding antimicrobial selection for effective treatment.
Area of Science:
- Microbiology
- Infectious Diseases
- Pediatric Surgery
Background:
- Anaerobic bacteria are increasingly implicated in pediatric infections.
- Post-surgical wounds (PSW) in children can harbor complex polymicrobial flora.
- Understanding the specific microbial profiles of PSW is crucial for effective management.
Purpose of the Study:
- To investigate the microbial composition of pediatric post-surgical wounds.
- To correlate wound flora with anatomical location and adjacent mucosal sites.
- To inform antimicrobial strategies for managing pediatric PSW.
Main Methods:
- Utilized adequate methods for aerobic and anaerobic bacterial recovery.
- Analyzed wound swabs from pediatric patients undergoing various surgeries.
- Correlated isolated microorganisms with surgical site and proximity to mucous membranes.
Main Results:
- Polymicrobial aerobic and anaerobic bacteria were isolated from over half of PSW patients.
- Staphylococcus aureus and aerobic gram-negative bacilli were common across all sites.
- Wound flora composition correlated with anatomical location: gut flora organisms (e.g., Enteric Gram-negative rods, Bacteroides fragilis) in gut-related wounds, and oral flora organisms (e.g., Streptococcus spp., Fusobacterium spp.) in oral-proximal wounds.
Conclusions:
- Pediatric post-surgical wound infections involve diverse polymicrobial flora.
- Microbial composition is site-specific, reflecting adjacent mucosal flora.
- Antimicrobial therapy for PSW should target polymicrobial organisms based on wound location.
Abstract:
The recent increased recovery of anaerobic bacteria from children has led to greater appreciation of their role in paediatric infections at all body sites, including post-surgical wounds (PSW). In studies that employed adequate method for recovery of aerobic and anaerobic bacteria polymicrobial, aerobic and anaerobes were isolated from over half of the patients with PSW. The wounds studied were those that developed following these surgical procedures: head and neck surgery for malignancies, post-thoracotomy, spinal fusion and gastrostomy tube insertion. Staphylococcus aureus and aerobic gram-negative bacilli were found at all sites. However, a correlation was generally found between the site of the wounds and microbial flora recovered from the wound. Organisms that resided in the mucous membranes close to the surgical site predominated in the wound next to these areas. Enteric Gram-negative rods, Group D enterococcus and Bacteroides fragilis group predominated in wounds relating to the gut flora, while Streptococcus spp., pigmented Prevotella and Porphyromonas spp. and Fusobacterium spp. were most frequently recovered in wounds proximal to the oral area. Management of PSW should include administration of antimicrobials effective against the polymicrobial bacterial flora adjacent to the anatomic site of the wound.
