Continuous renal replacement therapy. Keeping pace with changes in technology and technique.
The rapidly changing nature of new technologies and techniques in acute health care means it can be difficult keeping pace. Most facilities, large or small, are usually in continuous evaluation of a new technology. Published reviews and professional group guidelines can assist the process of change for continuous renal replacement therapy (CRRT) technologies and techniques. The current techniques and technologies are a mixed application of old and new technologies providing a combination of convective and diffusive solute clearance methods. There are a variety of anticoagulation approaches. New, purpose-built CRRT machines offer many advantages over old technology but their costs can be prohibitive and users do not always meet them with rapid behavioral change. Reading journal publications and texts, scientific meetings, education and training, Internet web site review/participation, quality improvement activities and an accurate local data base are the keys to keeping pace with changes and identifying whether a benefit can be anticipated and demonstrated. Possible changes for the future of techniques and technologies may be in the areas of modified approaches to continuous therapy with tailored approaches for specific patient care settings. Improved membrane characteristics for wider indications and the bio-artificial kidney are emerging along with blood pump and circuit design improvements, with new machine/operator interfaces.
