Abstract
60 minutes after i.v. injection tissue levels of 7 different cephalosporins were obtained using biological assay. The following concentrations were measured: cephalothn 1.4 micrograms/g; cepharin 4.7 micrograms/g; cephacetrile 11.2 micrograms/g; cephradine 15.4 micrograms/g; cefazedone 26.9 micrograms/g; cefamandole 40.3 micrograms/g, and finally cefoxitin 43 micrograms/g. The high tissue levels of cefamandole and cefoxitin are especially remarkable as i.v. doses of both antibiotics had been 50 mg/kg body weight ( doses of all other cephalosporins 100 mg/kg body weight). Except cephalothin, all cephalosporins tested were suitable for antibiotic prophylaxis in cardiac surgery.
