ABSTRACT
Cardiopulmonary bypass and hypothermia (HCPB) is a procedure commonly used during heart surgery, representing a risk factor for the patient by promoting extensive haemodilution and profound physiological changes. Cefuroxime is used for the prevention of infection following heart surgery, and several dose schemes have been suggested for prophylaxis with cefuroxime. The objective of the present study was to assess, in a comparative manner, the systemic availability of cefuroxime administered intravascularly as a bolus dose of 1.5 g to 17 patients having heart surgery with or without HCPB. Plasma cefuroxime concentrations were determined by high-pressure liquid chromatography-UV, and the following values, expressed as medians, were obtained for the study group compared with controls 69.1 vs. 62.7 mg/L (1st h), 35.8 vs. 26.0mg/L (3rd h), 14.6 vs. 8.7 mg/L (6th h, P<0.05), 6.1 vs. 3.0mg/L (9th h, P<0.05) and 2.6 vs. 1.0mg/L (12th h, P<0.05). Despite the differences recorded during the study period as a consequence of HCPB, low antibiotic concentrations were found as early as 6h post dose for both groups investigated. Thus, the low systemic availability of cefuroxime after the administration of a 1.5-g dose may not protect against postoperative infections. The data obtained permit us to recommend a change in the dose scheme in order to maintain adequate plasma levels of cefuroxime.
