| Scientific title | An evaluation of ciprofloxacin pharmacokinetics in critically ill patients undergoing continuous veno-venous haemodiafiltration |
| Study objectives | Under dosing of antibiotics has enabled the genesis of resistant strains and this is particularly an issue with fluoroquinolones. Altered drug pharmacokinetics, due to disease, results in variable antimicrobial drug clearance in critically ill patients (antibiotic regimens are often developed on the basis of drug disposition in non-critically ill volunteers) and further complicates the selection of appropriate dosing schedules for these patients. The goal of ciprofloxacin therapy is to maximise the 24 hour Area Under the Curve/Minimum Inhibitory Concentration and the peak/MIC ratios. A number of papers have highlighted the requirement for a re-evaluation of currently recommended antimicrobial dosage regimens for critically ill patients. |

| Health condition(s) or problem(s) studied | Patients on dialysis |
| Intervention | 1. Timed serum samples were collected during each dosage interval and ultrafiltrate during 7 dosage intervals (1 per patient) 2. Effluent fluid was collected for the entire dosage interval 3. The volume of each hourly batch was recorded and a 40ml sample was taken for analysis 4. Aliquots from each sample were analysed for ciprofloxacin concentration and for creatinine determination 5. Total ciprofloxacin concentrations in serum and effluent were measured by a HPLC method 6. Serum concentrations, from an indwelling arterial cannula, were measured immediately before the infusion was started, immediately after the infusion finished and at 2,3,4,6,8 and 12 hours post infusion where the dosage interval was 12 hours 7. When the prescribed dosage interval was 24hr samples were also taken at 18 and 24hrs 8. Exact sampling times were recorded |
| Intervention type | Other |
| Primary outcome measure | To obtain reliable estimates of ciprofloxacin pharmacokinetic parameters for patients in intensive care unit (ICU) on Continuous veno-venous hemodiafiltration (CVVHDF) |
| Secondary outcome measures | To describe achieved pharmacodynamic parameters in these patients |
