title: Comparative study between two prophylactic antibiotic regimens of cefamandole during coronary artery bypass surgery.
abstract: 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.
