Official title
Cefazolin Antibiotic Prophylaxis in Ventricular Shunt Surgery: Determination of Cerebrospinal Fluid(CSF) Concentration During Valve Implantation
Overview
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.
Interventions
- Other Cefazolin antibiotic prophylaxis
Determination of cerebrospinal fluid concentration
Primary outcome measures
- Cefazolin concentration in the cerebrospinal fluid [Time frame: The measure is made when the dura mater is opened just before the valve implantation.]
Secondary outcome measures (4)
- blood cefazolin concentration [Time frame: Blood samples are made before injection]
- blood cefazolin concentration [Time frame: Blood samples are made 30 minutes , after injection]
- blood cefazolin concentration [Time frame: Blood samples are made 1hour after injection]
- blood cefazolin concentration [Time frame: Blood samples are made 2 hours after injection]
