Background and Goal of Study: This work is a retrospective descriptive and analytical study of
documented infections related to the central venous catheters, spread over a period of one year,
from January 2015 to December 2015, carried out in the medical resuscitation department of the Ibn
Rochd Hospital in Casablanca, Morocco.
Materials and Methods: Included were all patients with central venous catheterization, with or
without bacteraemia, after hospitalization in the medical resuscitation unit of Ibn Rushd Hospital for
more than 48 hours.
Results and Discussion: Gramnegative
bacilli were isolated from the culture of central venous
catheters in 40.5% of cases. Grampositive
cocci represented a rate of 35.1%, coagulasenegative
staphylococcus is the most frequently isolated with a rate of 84.61 %. Grampositive
bacilli represent
a rate of 8.2%.
Acinetobacter baumannii is found to be 26.6%, is resistant to 100% Imipenem, sensitive to Amikacin,
Gentamycin, Cefepime and Netilmycin Klebsiella pneumoniae is found 26.6%, it is resistant to 75%
Ampicillin and Cefotaxime, and sensitive to 75% at Imipeneme, Amikacin and Cefoxitin.
For Proteus mirabilis, 50% were resistant to ampicillin, cefalotine and imipeneme.
The rate of enteric bacteria producing ESBL was 62.5%. For Pseudomonas aeruginosa, 100% were
resistant to imipenem, ceftazidime, gentamycin and Netilmycin.
Staphylococcus coagulase negative was resistant to Penicillin G with a rate of 72.7% and 63.6% to
kanamycin with a sensitivity of 100% to teicoplanin.
Conclusion(s): The main problem in intensive units are nosocomial infections .The infections
related to central venous catheters are a risk and they can be due to multiresistant bacterias .In our
study, Acinetobacter baumanii is the main germ and it is resistant to imipenem in 100%. A strategy of
managing antibiotherapy is essential in intensive care so are preventive measures in nursing and
catheters cares.
