A randomised, double-blind study was performed in two groups of 15 patients undergoing total hip replacements, using antibiotic-loaded acrylic cement containing 0.5 g and 1.0 g gentamicin base respectively per 40 g pack of powdered polymer. Postoperatively, the gentamicin levels in the blood, in the urine and in the wound drainage fluid were measured. In both groups of patients, the serum gentamicin concentrations were low whereas the wound drainage fluid contained highly effective antibacterial concentrations. Serum, urine and wound secretion levels showed approximately two-fold higher concentrations in the group of patients receiving the higher gentamicin load.
