Comparison of the efficacy of "Trisdine" and kanamycin-colistin bladder instillations in reducing bacteriuria during intermittent catheterisation of patients with acute spinal cord trauma.
An open, prospective, randomised, comparative study of "Trisdine" and kanamycin-colistin bladder instillations in reducing significant bacteriuria during intermittent urethral catheterisation was conducted. Trisdine is an aqueous solution of chlorhexidine gluconate 0.01% with added ethylenediaminetetra-acetic acid disodium salt and TRIS buffer at final concentrations of 1.34 mMoles and 0.01 Molar respectively. All patients (15 males and 3 females) admitted with acute spinal cord trauma and bladder involvement requiring intermittent catheterisation for more than 5 days during a 12-month period were studied. There was no significant difference in the mean incidence of significant bacteriuria during intermittent catheterisation in the 7 males who had kanamycin-colistin bladder instillations compared with the 8 males who had Trisdine instillations. A comparison could not be made in the females because there were only 3 patients. Because Trisdine is more stable at ambient temperatures, is less likely to select antibiotic-resistant bacteria and is less expensive, it is concluded that Trisdine is preferable to kanamycin-colistin solution for bladder instillations during intermittent catheterisation.
