Antibiotic concentrations in the groin wound after vascular prosthetic implantation

The kinetics of systemically and locally administered cefuroxime or ceftazidime in wound fluid were investigated in the period after vascular prosthetic implantation. Cefuroxime or ceftazidime was administered intravenously in patients. Simultaneously 250 mg ceftazidime or cefuroxime was added to preclotted blood. Locally administered antibiotics could not be detected in our samples. In groin fluid samples 24–48 h after the operation the average concentration of cefuroxime was 8.3 and of ceftazidime 5.0 mg/l. The decline of the concentration of cefuroxime or ceftazidime in groin fluid seems to be much slower than one would expect from the half-lives of the antibiotics. We conclude that cefuroxime and to a lesser extent ceftazidime are suitable as prophylactic agents in arterial reconstruction.
