title: Elimination of meropenem during continuous veno-venous haemofiltration and haemodiafiltration in patients with acute renal failure.
abstract: Meropenem elimination was studied in six patients with acute renal failure on continuous venovenous haemofiltration (CVVH) or continuous veno-venous haemodiafiltration (CVVHDF) 1 L/h and 2 L/h for 12 h. Meropenem 1 g was given iv over three dialysis periods, and plasma, ultrafiltrate/dialysate and urine concentrations of meropenem were determined. The half-life of meropenem was significantly longer (P < 0.05) during CVVH (7.5 +/- 2.0 h; mean +/- S.D.) than during CVVHDF 1 L/h (5.6 +/- 1.4 h) or 2 L/h (4.8 +/- 1.2 h). Meropenem clearance was 3.27 +/- 2.30 L/h, 4.72 +/- 2.69 L/h and 5.71 +/- 3.58 L/h in CVVH, CVVHDF 1 L/h and CVVHDF 2 L/h, respectively (P < 0.05 between CVVH and CVVHDF). Patients with renal failure on CVVHDF 1 or 2 L/h should be treated with meropenem 1 g bid; 500 mg tid may be enough for patients on CVVH.
