Editorial Review Comparative Study
Ambulatory blood pressure monitoring is a useful clinical tool in nephrology.
Hypertension is a key factor in the genesis and deterioration of many renal diseases and is also a risk factor for death in patients with end-stage renal disease. However, the standard methods of measurement are prone to variability, especially in patients undergoing dialysis. The technique of ambulatory blood pressure monitoring allows a better assessment of overall blood pressure levels and promises to assume a bigger role in the care of renal patients. ⋯ The available evidence suggests that ambulatory blood pressure compared with blood pressure measured in the physician's office is better correlated to left ventricular mass in subjects with chronic renal disease. Furthermore, studies in subjects with chronic renal disease and those undergoing renal replacement therapy show that blood pressure control is suboptimal in many patients and that nocturnal blood pressure is generally higher than in control subjects. Further insights into overall blood pressure behavior in this population will certainly emerge in the future.

Continuous renal replacement therapy (CRRT) is performed in critical care units around the world with various levels of involvement from critical care and nephrology nurses. In this article, factors affecting the delivery of nursing care and the particular expertise nephrology and critical care nurses have in the area of CRRT are examined. ⋯ Based on related research findings and a comparison of the models, the Collaborative Model is the preferred one, as it brings the highest level of expertise directly to the patient. For the Collaborative Model to work, a framework for collaboration and a high degree of commitment from both specialties must be maintained.

The arrival of continuous renal replacement therapy (CRRT) has given the intensivist and the intensive care nurse the opportunity to treat acute renal failure (ARF) independently by giving them the necessary technology and taking CRRT away from absolute nephrological control. This structural shift has created a controversy between those countries where control of CRRT has completely shifted to the intensivist and those countries where nephrological input is still dominant. The argument in favor of intensivist-driven CRRT rests upon several observations, including the fact that therapy is continuous, as is the presence of the intensivist in the intensive care unit (ICU). ⋯ Intensivists are successfully performing more and more procedures that were previously seen as part of other specialties and, last but not least, "closed" models of ICU care appear to work best. Australian intensivists have taken up CRRT from the start and now control it. Patient outcomes under such a system, as reported here, are above average, and confirm the effectiveness of such an approach.
