[Bacterial studies of wound and drainage systems and their correlation with clinical findings]
Abstract:
The wound secretions of the 1st and 2nd postoperative day as well as the drain tip of the 2nd postoperative day were examined bacteriologically. As a result it was found that with the increasing duration of drainage there was also an increase of the contamination rate. The exchange of the suction flasks, which seldom is performed in a hygienically unobjectionable way, was found to be especially problematical. If several bacteriological data are available, the bacteriology of the wound drainage is a simple, but informative way to diagnose the situation of wound healing. It was possible in the present study on 103 Redon drainages to show at the 2 wound infections occurred that the bacteria and/or bacterial combinations ascertained in the wound secretion and at the drain tip were the very same as were found later when the wound infection application became manifest. The systematic application of antibiotics have influence upon the identification of germs and may be responsible for any falsely negative result. The correlation with clinical data, such as body temperature and wound infection, makes evident that in many cases the identification of germs in the drainage system is of clinical importance.
Insights
Bacteriological analysis of wound drainage and drain tips can predict wound infections. Increased drainage duration correlates with higher contamination rates, highlighting the importance of sterile techniques.
Area of Science:
- Microbiology
- Surgical Pathology
Context:
- Postoperative wound care involves managing surgical drains to prevent complications.
- Assessing wound healing often requires monitoring for signs of infection.
Purpose:
- To evaluate the diagnostic value of bacteriologic examination of wound secretions and drain tips in predicting postoperative wound infections.
- To investigate the correlation between drainage duration, contamination rates, and the occurrence of wound infections.
Summary:
- Bacteriological examination of wound secretions and Redon drain tips was performed on 103 patients.
- A rising contamination rate was observed with increased drainage duration.
- Identical bacteria were identified in wound secretions/drain tips and subsequent wound infections, confirming diagnostic utility.
- Antibiotic use can affect germ identification, potentially leading to false negatives.
Impact:
- Wound drainage bacteriology offers a simple yet informative method for diagnosing wound healing status.
- Findings underscore the clinical significance of identifying pathogens in drainage systems for timely intervention.
- Highlights the need for strict hygienic practices during suction flask exchange to minimize contamination.
