Intensity of continuous renal replacement therapy in acute kidney injury

The intensity of continuous renal replacement therapy (CRRT) is generally assessed on the basis of small solute clearance with dosing usually expressed in terms of total effluent volume per unit time (e.g., ml/kg/hour). Although several clinical trials have suggested an improvement in survival with higher doses of CRRT, results have not been consistent across all studies. The results of recent trials of intensity of CRRT are reviewed. The largest and most recent trials suggest that there is no additional benefit to using effluent flow rates in excess of 20 ml/kg/hour, although earlier studies suggested improved survival with doses of 35 to 45 ml/kg/hour.

Enfermería de cuidados críticos y técnicas continuas de reemplazo renal en la Comunidad de Madrid

The continuous renal replacement techniques (CRRT) aim to substitute the altered renal function during a period of time, presenting advantages compared to conventional hemodialysis (CH). This study aims to determine the situation of the CRRT in the Intensive care units (ICU) of the Madrid Community (MC) using a survey distributed to nurses (n = 131) of 14 ICU. It evaluates four aspects of the CRRT: management model, knowledge, problems and degree of satisfaction. It identified four models, the most frequent is that in which ICU nurse and intensivist participate (60%). Self-evaluation of knowledge was fair in 55.7% of the cases and the mean of correct responses in an evaluation of 10 questions was 4.19 and 5.45 in those with previous courses. A total of 84.7% think that CRRT significantly increases the workloads and 62.6% believe that they should be done by the ICU nurses. The main problem is the lack of knowledge to resolve complications during the technique. We conclude that the ICU nursing can handle the CRRT, adapting the nurse/patient ratio; training programs should be established and the role of the teaching nurse defined in critical renal cares.
