Clinical outcome following the use of inadequate solutions for continuous veno-venous hemodiofiltration

Backgrounds. A short time ago, commercially available diafiltration and replacement fluids could be found o n the hospital in Turkey. Instead, peritoneal dialysis solution (PDS) for continue veno-venous hemodiafiltration (CVVHDF) therapy and normal saline as replacement fluid are used. In this retrospective study, we investigated the effects of PDS and bicarbonate-buffered hemofiltration solution (Bic-HFS). Methods. We did a retrospective chart review of 24 patients treated with continue renal replacement therapy (CRRT) between January 2004 and February 2008. Peritoneal dialysis solution (PDS) was used in 14 patients, and bicarbonate-buffered hemodialysis solution (bic-HFS) was used in 10 patients. Results. Demographic data, laboratory findings, and mortality rate were similar both groups. Blood glucose and lactate levels were higher in the PD group than the bic-HFS group (p < 0.05). Hyperglycemia occurred more frequent in the PDS group than in the bic-HFS group (64% versus 30%, respectively; p < 0.05). Metabolic acidosis occurred in eight patients (57%) in the PDS group and three patients (30%) in the bic-HFS group (p < 0.05). Hypotension was higher in the PDS group (10, 71%) than in the bic-HFS group (3, 30%; p < 0.05). Conclusion. Using PDS fluid as dialysate for CVVHDF therapy is not a preferable solution because of the metabolic disturbances that it can cause. Copyright © Informa Healthcare USA, Inc.
