On-line continuous venovenous hemodiafiltration: a technique for the control of ultrafiltration and convection during continuous renal replacement therapy.

Continuous renal replacement therapies have been used increasingly in critically ill patients in nephrologic and intensive care units. These techniques are nevertheless time consuming and lack an easy control of ultrafiltration. We conducted continuous venovenous hemodialysis (CVVHD) on a dialysate delivery machine which ensures a volumetric control of ultrafiltration, and which produces both dialysate and infusate with the on-line technique.

[Three-and-a-half years' experience with hemodialysis using 37 Permcaths without infection or definitive thrombosis].

34 patients had 37 Quinton Permcath (PKT), surgically implanted in jugular vein (internal: 29, or external: 8). The first 20 were used for a temporary vascular access (mean: 21 weeks). Then, the next 17 were used for permanent vascular access.

[Influence of dialysis and kidney transplantation on the survival of patients with end-stage chronic kidney failure. A multifactorial analysis].

In a series of 296 patients treated in our centre by dialysis and/or renal transplantation over the last 15 years, the actuarial survival rates at 5, 10 and 15 years were 79, 68 and 57 percent respectively. Comparing the influence on survival of each of these two treatments separately should avoid two methodological biases represented by the sequential risk due to the succession of treatments and by different pretherapeutic situations. We therefore analysed these patients' survivals by the unbiased Mantel-Byar method, using a comparison of multiple survival factors (Cox's technique).

[Development of renal function in the transplanted patient with renal hypertension treated with enalapril].

We report our experience with a converting-enzyme inhibitor, enalapril, as antihypertensive agent in eighteen patients with hypertension after renal transplantation. Renal function was prospectively followed up. Six patients demonstrated an acute renal failure episode (defined by a 25% increase of serum creatinine during enalapril therapy).
