Vancomycin is commonly added to acrylic bone cement during revision
arthroplasty surgery. Proprietary cement preparations containing
vancomycin are available, but are significantly more expensive.
We investigated whether the elution of antibiotic from ‘home-made’
cement containing vancomycin was comparable with more expensive
commercially available vancomycin impregnated cement. A total of 18 cement discs containing either proprietary CopalG+V;
or ‘home-made’ CopalR+G with vancomycin added by hand, were made.
Each disc contained the same amount of antibiotic (0.5 g gentamycin,
2 g vancomycin) and was immersed in ammonium acetate buffer in a
sealed container. Fluid from each container was sampled at eight
time points over a two-week period. The concentrations of gentamicin
and vancomycin in the fluid were analysed using high performance
liquid chromatography mass spectrometry.Aims
Materials and Methods
Patient warming significantly decreases the risk
of surgical site infection. Recently there have been concerns that forced
air warming may interfere with unidirectional airflow, potentially
posing an increased risk of infection. Our null hypothesis was that
forced air and radiant warming devices do not increase the temperature
and the number of particles over the surgical site when compared
with no warming device. A forced air warming device was compared with
a radiant warming device and no warming device as a control. The
temperature and number of particles were measured over the surgical
site. The theatre was prepared as for a routine lower-limb arthroplasty
operation, and the same volunteer was used throughout the study. Forced air warming resulted in a significant mean increase in
the temperature (1.1°C
