[The risk of sepsis induced via the deep venous approach]
Abstract:
In order to determine the sepsis induced by the practice of canalizing the deep venous sector in revascularized patients, 43 catheters removed from 43 patients were cultured; no sepsis induced by this practice was found and 13 catheters had positive cultures, which amounted to 30.3% of the sample under study; five catheters (38.4%) with positive cultures belonged to patients who showed no sepsis; eight catheters (61.5%) with positive cultures corresponded to patients who showed septic focci. The average stay was 4.07 days. The germ most frequently found was negative coagulase staphylococcus.
Insights
Deep venous catheterization in revascularized patients did not cause sepsis. While 30.3% of catheters showed positive cultures, most belonged to patients without sepsis, with coagulase-negative staphylococcus being the most common germ.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Vascular Surgery
Context:
- Deep venous catheterization is a common practice in revascularized patients.
- Catheter-related infections pose a significant risk in healthcare settings.
- Understanding infection sources is crucial for patient safety.
Purpose:
- To investigate the incidence of sepsis directly induced by deep venous catheterization in revascularized patients.
- To determine the rate of catheter colonization and its correlation with sepsis in this patient population.
Summary:
- A study cultured 43 catheters from 43 revascularized patients to assess sepsis risk from deep venous catheterization.
- No sepsis cases were directly attributed to this practice.
- Positive cultures were found in 30.3% of catheters; 61.5% of these were from patients with existing septic foci, while 38.4% were from patients without sepsis.
- Coagulase-negative staphylococcus was the most frequently identified microorganism.
- The average patient stay was 4.07 days.
Impact:
- This study suggests that deep venous catheterization itself may not be a primary cause of sepsis in revascularized patients.
- Findings highlight the importance of differentiating catheter colonization from true catheter-related bloodstream infections.
- Results can inform clinical guidelines regarding catheter management and infection control protocols in vascular surgery patients.
