Abstract |
Objective |
The purpose of this retrospective study was to describe a tertiary care center experience with different antibiotic strategies that include cloxacillin (C) in patients with severe septic bursitis (SB).
Methods |
A severe SB was considered when the patient needed hospitalization and/or intravenous (i.v.) antibiotics. Patients were treated with bursal aspiration and one of these antibiotic options: C, 2 g/4 h per day i.v. until improvement, and afterwards 1 g/6 h per day v.o. until resolution; (C+G), gentamicin i.v. was added to C for 5 to 7 days (initial dose 240mg/d); (C+R), rifampicin was added at a dose of 600mg/d v.o.
Results |
The study comprised 82 patients with severe SB. The mean delay to diagnosis was 6.1±6.9 days, and the most frequent location was the prepatellar bursa. In 67%, the bursal fluid culture yield a positive result, being Staphylococcus aureus the most frequent bacteria isolated (94.4%). At admission, fever and extensive cellulites were more frequent in the C+G group. Patients in the C+G had a longer duration of i.v. antibiotics compared with the C group (p=0.008), although the total duration of antibiotics was not different. There was a tendency in the C+R group to need more surgery. All patients except one had a complete resolution and there were no differences in side effects.
Conclusion |
In patients with severe SB without extensive cellulites i.v., C alone may be sufficient. In patients with a more severe presentation, C plus gentamicin seems to be an appropriate option in the majority of them.
