Abstract
Introduction :
Hemodialysis catheters are prone to infectious complications. The aim was to determine the frequency of infections related to central venous catheters in hemodialysis patients at the Niamey reference hospital, the associated risk factors and the germs involved.
Materials and methods :
This is a prospective and descriptive study of catheter infections for 37 months, in the hemodialysis and bacteriology unit. We systematically cultured the tips of the catheters without performing blood cultures.
Results :
53 catheters were placed in 41 patients with a frequency of 56.66% of infected catheters. The average age is 47.05 +/- 15.68. The M/F sex ratio was 1.9. Catheters in the femoral position were the most infected in 47.16% (25 cases). Catheter infection was more frequent in patients with CKD in (22 cases) 41.51%. Twenty-one catheters or 70% were infected within two weeks and the non-tunneled catheters were more infected (28 cases). Catheters were removed in patients with systemic inflammatory response syndrome (18 cases) 33.96%. The germs isolated were gram-positive cocci (staphylococcus 56.52% (13 cases) including staphylococcus aureus in 18.87%) and gram-negative bacilli in 43.48% (pseudomonas aeruginosa (8 cases) 15.09%, Eschrichia coli (4 cases) 17.39%, Klebsiella pneumoniae (2 cases) 3.77%, Klebsielle oyxtoca (1 case), acinobacter baumannii (1 case) and Proteus mirabilis (1 case).
Conclusion :
The frequency of infections related to hemodialysis catheters is high. A study on adherence to prevention protocols when handling catheters by the dialysis care team should be conducted to identify the factors involved.
