In two groups of patients undergoing coronary artery bypass grafting
(CABG), two different regimens of antibiotic prophylaxis with cefamandole
nafate were compared. In Group 1, 30 mg per kilogram of body weight was
administered intravenously during induction of anesthesia. In Group 2, a
second dose of 15 mg/kg was administered intravenously shortly before
cannulation. Serum and tissue levels in the right atrium, the pericardium,
and the sternum were determined using high-pressure liquid chromatography.
The results showed that in Group 2 the serum levels were significantly
higher from 48 minutes onward after induction and remained at an acceptable
level during CABG. The tissue levels in the sternum and pericardium were
also significantly higher in Group 2 compared with Group 1. It is concluded
that a second dose of cefamandole (15 mg/kg) shortly before the beginning
of cardiopulmonary bypass is recommended, particularly for high-risk
patients.
