NCT07067736

Brief Summary

The objective is to determine the concentration of cefazolin in the cerebrospinal fluid after a recommended antiobiotic prophylaxis by 2g of cefazolin. Our main hypothesis is that the concentration is insufficient to protect the valve from infections. The secondary objective is to compare our results to known pharmacokinetic models of cefazolin diffusion in the literature. If differences are found we would like to search clinical features that could explain it.

Outcome Measures

Primary Outcomes (1)

  • Cefazolin concentration in the cerebrospinal fluid

    Cefazolin concentration in the cerebrospinal fluid.

    The measure is made when the dura mater is opened just before the valve implantation.

Secondary Outcomes (4)

  • blood cefazolin concentration

    Blood samples are made before injection

  • blood cefazolin concentration

    Blood samples are made 30 minutes , after injection

  • blood cefazolin concentration

    Blood samples are made 1hour after injection

  • blood cefazolin concentration

    Blood samples are made 2 hours after injection
