The objective was to investigate the plasma levels and to compare the pharmacokinetics of cefuroxime during and after surgery in adult patients with elective indication for coronary artery bypass grafting. ⋯ The kinetic disposition of cefuroxime remains unaltered in patients undergoing coronary artery bypass grafting; to reduce the fluctuation in plasma concentrations so that the antibiotic prophylaxis in the peri-operative period is guaranteed, the dose regimen should be reviewed.

Trauma caused by traffic accidents is among the main etiologies involved in the occurrence of facial fractures throughout the world. However, the trauma mechanisms involved are different according to the location where the study was performed, due to different conditions of development, legislation, and culture. A retrospective study was done between February 2001 and July 2006, with the purpose of determining the epidemiology and the mechanisms involved in the occurrence of facial fractures among car occupants in the metropolitan area of São Paulo. ⋯ The data collected indicate that the driver position shows a high incidence of facial fractures, not being effectively protected by the seat belt, although the wearing of seat belts seems to have a protective role against the occurrence of facial fractures in front-seat passengers. It was not possible to evaluate the wearing of seat belts among rear-seat passengers, even though the high incidence of fractures in this group showed its high susceptibility to the occurrence of facial fractures, which highlights the need of taking protective measures against this situation.
