Problems and advantages of continuous renal replacement therapy*
Authors:Merlin C THOMAS  David CH HARRIS
Abstract:SUMMARY: The continuous replacement of renal function must facilitate fluid and solute homeostasis, nutrition and vital organ function, and, where possible, hasten the recovery of renal function. Difficulties with anticoagulation, biocompatibility, mobility and cost remain obstacles to be overcome. the use of continuous renal replacement therapy (CRRT) to remove systemic inflammatory mediators is yet to be confirmed. Although survival benefits of CRRT over intermittent dialysis remain controversial, the slow continuous removal of fluid, acid and solute has a number of advantages, especially where patients are haemodynamically unstable.
Keywords:acute renal failure  continuous renal replacement therapy  haemofiltration  heamodialysis  ultrafiltration
