Introduction:
The aim of this study was estimate correlation between catheter clotting and catheter-related injection in haemodialysis (HD) patients with temporary double lumen catheters (TDLC).
Methods:
We analysed 128 TDLC where we had exact microbiological result from catheter tip. There were 107 patients, mean age 54.70 +/- 15.02 years (15.80); 52 (48.60%) male ad 55 (51.40%) female, which were on haemodialysis 1162.62 +/- 183,424 (6-7200) days.
Results:
Major reasons for application TDLC were acute HD in 56 (43.75%), a function of A-V fistula in 40 (31.25%) patients, and a function of previous TDLC in 32 (25%) patients. The primary causes of chronic renal disease were diabetes mellitus in 34 (27%), pyelonephritis in 31 (24%), glomerulonephritis in 24 (19%), polycistic kidney disease in 14 (11%), nephropathia endemic in 10 (8%) and others disease in 15 (12%) of patients. The analysed TDLC remained in place for an average of 51.34 +/- 64.03 (range 2-518) days. In case of 92 (71.88%) we got positive microbiological result (Staphylococcus coagulasa negative 33%, Staphylococcus aureus 16%, Bacillus species 9%). In 38 of these catheters (41.30%) we diagnosed problems with blood flow. Totally, we had 50 TDLC with obstruction, but in 12 of them we did not have microbiological confirmation of infection.
Conclusion:
Catheter clotting is one of the important factors that increase risk for developing catheter-related infection.
Insights
Catheter clotting is a significant risk factor for catheter-related infections in haemodialysis patients. This study found a correlation between blocked temporary double lumen catheters (TDLC) and infection development.
Area of Science:
- Nephrology
- Infectious Diseases
- Medical Devices
Context:
- Haemodialysis (HD) patients often require temporary double lumen catheters (TDLC) for vascular access.
- Catheter-related complications, including clotting and infection, can impact treatment efficacy and patient safety.
Purpose:
- To investigate the correlation between catheter clotting and the incidence of catheter-related infections in patients undergoing haemodialysis with TDLC.
Summary:
- A study analyzed 128 TDLCs in 107 haemodialysis patients, finding that 50 catheters experienced obstruction.
- Microbiological analysis revealed positive results in 71.88% of catheters, with Staphylococcus species being common pathogens.
- Catheter clotting was diagnosed in 41.30% of cases with blood flow issues, highlighting its association with infection risk.
Impact:
- Findings suggest that catheter clotting is a critical factor contributing to the development of catheter-related infections.
- Understanding this relationship can inform strategies to prevent complications and improve outcomes for haemodialysis patients.
