[Penetration activities of cefoxitin into different human tissues. An experimental study (author's transl)]

Subject of the following study was the penetration activity of cefoxitin into different human tissues. The authors obtained material of the cutis, subcutis, fascia, muscle, spongy bone and compact bone during orthopedic surgery on 20 patients. Cefoxitin was administered by means of a continual infusion of a dose of 45 mg per kg body weight per hour. Tissue and serum levels were studied after infusions lasting 15, 60, 90 and 120 minutes. Altogether the results of 215 specimens of serum and 132 specimens of tissue are recorded. The evaluation showed the following mean tissue levels of cefoxitin: 6.6 micrograms/g in compact bone; 14.4 micrograms/g in spongy bone; 23.3 micrograms/g in muscle; 64.2 micrograms/g in fascia, 69.9 micrograms/g in cutis and 21.7 micrograms/g in subcutis.
