Infections associated with subclavian Uldall catheters

Area of Science:

• Nephrology
• Infectious Diseases
• Vascular Access

Background:

• Vascular access is crucial for hemodialysis and plasmapheresis.
• Subclavian vein Uldall catheters (UC) are used for temporary vascular access.
• Infection rates associated with different vascular access types vary.

Purpose of the Study:

• To prospectively evaluate the incidence of infection and bacteremia associated with Uldall catheter (UC) use.
• To compare the infection rates of UC with other temporary vascular access methods.

Main Methods:

• Prospective study over 12 months.
• Involved 27 patients requiring hemodialysis or plasmapheresis.
• Monitored UC site infections and associated bacteremias.

Main Results:

• Ten out of 27 patients developed UC site infections.
• Common pathogens included Staphylococcus epidermidis and Staphylococcus aureus.
• Five patients experienced bacteremia, with one fatality linked to bacteremia.
• UC demonstrated a higher incidence of infection and bacteremia compared to other vascular access methods.

Conclusions:

• The Uldall catheter (UC) is associated with a high incidence of site infections and bacteremia.
• Current data suggest UC may have a higher risk profile than other temporary vascular access options.
• Further investigation is required to establish the safety and efficacy of UC for routine temporary vascular access.
