title: Treatment of twelve burn wound infections and eight other serious infections with cefazolin and tobramycin: in vitro and in vivo evaluation.
abstract: 20 patients with serious infections were treated with cefazolin and tobramycin for 9--64 days. Minimal inhibitory concentration (MIC) values and minimal bactericidal concentration (MBC) values were determined for each of the 112 clinical bacterial isolates. The median cefazolin MIC/MBC was 1.56/12.5 micrograms/ml, and the median tobramycin MIC/MBC was 6.25/25.0 micrograms/ml for all organisms studied. Median cefazolin doses of 49.0 mg/kg/day gave median peak/trough serum levels of 43.0/11.0 micrograms/ml. Median tobramycin doses of 4.3 mg/kg/day gave median peak/trough serum levels of 5.0/1.4 micrograms/ml. Checkerboard studies revealed synergy with 65% of strains. Bacteriologic and clinical success was obtained in 17 of 20 patients.
