Abstrakt: Objectives: To determine whether a prophylactic second dose of antibiotics is justified when severe blood loss and/or prolonged operation time occurs during aortoiliac reconstructions.
Methods: We measured the cefuroxime concentration in venous blood serum and subcutaneous fat tissue of 30 patients who underwent elective aortoiliac reconstruction after a single intravenous dose of 1500 mg cefuroxime.
Results: The mean blood loss was 1912 ml (range 200-7000). The mean operation time was 212 min (range 70-330). The cefuroxime concentration in blood serum 30 min after the gift varied from 53.7-561.6 mg/l and during closure of the abdominal incision from 13.2-90.0 mg/l. Taking the minimum inhibitory concentration for Staphylococcus species as 1.0 mg/l, we found an adequate prophylactic serum cefuroxime concentration in all patients. There was a statistically significant correlation between serum cefuroxime concentration and blood loss (p = 0.01) and operation time (p = 0.0001).
Conclusions: Although serum concentration of cefuroxime is greatly influenced by blood loss and operation time, a second dose of cefuroxime in aortoiliac reconstructions is not necessary if the operation is completed within 5.5 h and if perioperative blood loss does not exceed 7000 ml.
