Abstract:
We report 16 orthopaedic patients who had antibiotic-associated diarrhoea (pseudomembranous colitis) after operation. There was an association with the use of cephradine and with the prolongation of prophylaxis for more than three peri-operative doses. Five cases occurred as a cluster, suggesting that the causative agent, Clostridium difficile, may be infectious in some situations.
Insights
Antibiotic-associated diarrhea, or pseudomembranous colitis, occurred in 16 orthopedic patients post-operation. This condition was linked to cephradine use and extended prophylactic antibiotic durations, with some cases suggesting Clostridium difficile infection transmission.
Area of Science:
- Orthopaedic Surgery
- Infectious Diseases
- Gastroenterology
Background:
- Antibiotic-associated diarrhea (AAD) is a significant complication following surgical procedures.
- Pseudomembranous colitis, a severe form of AAD, is often linked to Clostridium difficile.
- Orthopaedic surgery patients may be at increased risk due to prolonged antibiotic prophylaxis.
Purpose of the Study:
- To investigate the incidence and potential risk factors for antibiotic-associated diarrhea in post-operative orthopaedic patients.
- To identify specific antibiotics or treatment durations associated with the development of pseudomembranous colitis.
- To explore the possibility of Clostridium difficile transmission in a clinical setting.
Main Methods:
- Retrospective case review of 16 orthopaedic patients diagnosed with antibiotic-associated diarrhea post-operation.
- Analysis of antibiotic regimens, focusing on cephradine and duration of peri-operative prophylaxis.
- Clinical observation for clustered cases suggestive of infectious transmission.
Main Results:
- Sixteen orthopaedic patients developed antibiotic-associated diarrhea (pseudomembranous colitis) after surgery.
- A significant association was observed between cephradine use and AAD.
- Prolongation of prophylactic antibiotic therapy beyond three peri-operative doses was also linked to AAD.
- Five cases presented as a cluster, indicating potential infectious spread.
Conclusions:
- Cephradine and extended peri-operative antibiotic prophylaxis are risk factors for AAD in orthopaedic patients.
- Clostridium difficile, the causative agent, may be transmitted between patients in certain healthcare settings.
- Judicious antibiotic use and prophylaxis duration are crucial in preventing AAD post-orthopaedic surgery.
