Tissue levels of cephradine in ischaemic limbs following a single intravenous injection.
A single dose of 2g cephradine was administered intravenously at the time of anaesthetic induction to 20 patients with occlusive arterial disease. Concentrations of cephradine were measured in serum, subcutaneous fat from the groins of 10 patients underdoing arterial reconstruction and in the subcutaneous fat and skeletal muscle of 10 legs amputated for severe arterial ischaemia. Concentrations of cephradine were adequate for antibacterial prophylaxis at the time of operation in all serum samples, 9 out of 10 samples of subcutaneous fat from reconstruction cases, all muscle and 8 of 10 fat samples from the level of section of amputated limbs, and in 8 of 10 muscle and fat samples from the distal parts of amputated limbs. These results confirm that a single intravenous dose of 2 g cephradine given with anaesthetic provides adequate serum and tissue concentrations for antibacterial prophylaxis during vascular surgery.
