Bacteriological aspects of catheters related infections linked at Dalal Jamm hospital in Guédiawaye (Senegal).

Abstract

Introduction : Objective : The use of catheters is frequent in hospital but catheter related infections are the main complications, and those infections are major sources of bacteremia. The aim of this study is to determine the epidemiological and bacteriological profiles of venous catheter-related infections at the Dalal Jamm Hospital in Guédiawaye. Methodoly : During 18 months, a retrospective prospective study is conducted at the laboratory of the Dalal Jamm National Hospital Center. Tips of central, umbilical and peripheral venous catheters were received. After reception, culture on broth, isolation on agar, identification of the biochemical and antigenic characters if necessary and antimicrobial sensibility tests (AST) on the strain(s) identified were performed. Results : A total of 41 catheters were received from patients aged 0 to 78 years: 29% aged 0 to 18 months and 29% over 40 years old. The sex ratio was 1.05. The 26 were central venous catheters which mainly came from intensive care unit (46.15%) and nephrology (38.46%); and 11 were umbilical catheters.
The 32 isolated germs were distributed as follows: 37.5% (n = 12) were enterobacteria, mainly Klebsiella pneumoniae, 7 strains of Pseudomonas aeruginosa and 4 strains of Staphylococci. These were mainly multi-resistant bacteria: all strains of Staphylococci were meti-R and 58.3% of enterobacteria were eESBL. Conclusion : Catheter-related infections constitute a particular form of healthcare-associated infection and it is real a public health problem. It is important to monitor and prevent their occurrence because they are associated with an increase in the risk of mortality and morbidity, cost and long stay in hospital.
