Prevalence of Bacterial infections in subclavian double lumen catheter for haemodialysis in Najaf governorate, Iraq

Abstract

Abstract Background and objectives: The insertion of a subclavian dialysis catheter is a common invasive procedure used in patients with chronic renal failure in Iraqi hospital. our aim was to evaluate the risk factors for infection associated with insertion of a double lumen haemodailysis catheter.Patients and methods: 322 patients with chronic renal failure attending Alsader teaching Hospital in Najaf Governorate from January 2009 to January 2010. Patients divided into three groups the first group those with subclavain double lumen dialysis catheter inserted for the first time ,second group catheter inserted for the second time and third group those with the catheter inserted for third time. Culture was done from swab of skin around the catheter ,clot from catheter and blood. Also blood urea and serum creatinin was done to each patients.Results:130 isolates were recovered from different specimens the common bacterial isolates(51.5%) were Aeromonas hydrophila from skin of patients followed by Staphylococccus aerueus (30.7%), Staphylococccus epidermidis (22.3%) and Pseudomonas aeruginosa (9.2%).Conclusions: More frequent changing of subclavain double lumen dialysis catheter and advanced stage with chronic renal failure are common cause of increase infection in subclavian double lumen haemodialysis catheter. Aeromonas hydrophilia is the most common bacteria encountered in subclavian double lumen haemodialysis catheter.
