Insights

Surgical site infections (SSIs) are common after perforation peritonitis. Cultures of peritoneal fluid and surgical wounds show consistent pathogens, justifying routine fluid cultures to guide antibiotic therapy.

Area of Science:

  • Infectious Diseases
  • Surgical Infections
  • Microbiology

Background:

  • Surgical site infection (SSI) is a significant complication following perforation peritonitis.
  • SSIs contribute to increased patient morbidity and mortality.

Purpose of the Study:

  • To investigate the consistency of microbial pathogens and their antibiotic sensitivity between intra-peritoneal fluid and post-operative wound cultures in patients with perforation peritonitis.
  • To determine if routine peritoneal fluid cultures can guide empirical antimicrobial therapy.

Main Methods:

  • Collected intra-peritoneal fluid and post-operative wound samples from patients undergoing surgery for perforation peritonitis.
  • Performed microbial culture and antibiotic sensitivity testing on all collected samples.
  • Compared the results of pathogen identification and sensitivity patterns between paired samples.

Main Results:

  • A high degree of consistency (80.6%) was observed in both the type of pathogen and its antibiotic sensitivity between intra-peritoneal fluid and post-operative wound cultures in 25 cases.
  • This consistency suggests that peritoneal fluid accurately reflects the microbial environment influencing wound infections.

Conclusions:

  • Routine culture and sensitivity testing of peritoneal fluid in cases of perforation peritonitis is clinically justified.
  • Adjusting empirical antimicrobial therapy based on peritoneal fluid culture results can optimize treatment and potentially reduce SSI rates.
