RESUMEN
Acute kidney injury (AKI) commonly occurs in the intensive care unit and is associated with significant morbidity and mortality. Patients with AKI often require initiation of dialysis to control electrolytes, metabolic abnormalities, and volume status. This review will discuss controversies in renal replacement therapy (RRT), including timing of dialysis initiation, dialysis modality and dose, nonrenal indications for dialysis, and the patient population best suited for RRT therapy.

Rapid response teams (RRTs) were implemented to provide critical care services for deteriorating patients outside of intensive care units. To date, research on RRT has been conflicting, with some studies showing significant mortality benefit and reduction in cardiac arrest events and others showing no benefit. However, studies have consistently showed improved outcomes when RRTs work closely with primary services. Baseline data analysis at our institution found that primary services were present only on 50% of RRT activations. This quality improvement project aimed to improve the presence of primary services during RRT activations by 25%. With a survey, the main barrier that prevented primary services to be present was identified as the primary services' failure to recognize them as a crucial part of the RRT. Education tools and in-person sessions were implemented reinforcing the importance of primary services presence during RRT activations. The intervention leads to increasing presence of primary services at RRT activations, transfers to higher level of care, and changes in code status. However, there was no difference in hospital or intensive care unit length of stay or in survival.

BACKGROUND: Given the known deleterious effects seen with bicarbonate supplementation for acidemia, we hypothesized that utilizing high bicarbonate concentration replacement solution in continuous venovenous hemofiltration (CVVH) would be independently associated with higher mortality. METHODS: In a propensity score-matched historical cohort study conducted at a single tertiary care center from December 9, 2006, through December 31, 2009, a total of 287consecutive adult critically ill patients with Stage III acute kidney injury (AKI) requiring CVVH were enrolled. We excluded patients on maintenance dialysis, those who received other modalities of continuous renal replacement therapies, and patients that received a mixed of 22 and 32 mEq/L bicarbonate solution pre- and post-filter. The primary outcome was in-hospital and 90-day mortality rates. RESULTS: Among enrollees, 68 were used 32 mEq/L bicarbonate solution, and 219 received 22mEq/L bicarbonate solution for CVVH. Patients on 32 mEq/L bicarbonate solution were more often non-surgical, had lower pH and bicarbonate level but had higher blood potassium and phosphorus levels in comparison with those on 22 mEq/L bicarbonate solution. After adjustment for the baseline characteristics, the use of 32 bicarbonate solution was significantly associated with increased in-hospital (HR = 1.94; 95% CI 1.02-3.79) and 90-day mortality (HR = 1.50; 95% CI 1.03-2.14). There was a significant increase in the hospital (p = .03) and 90-day (p = .04) mortality between the 22 vs. 32 mEq/L bicarbonate solution groups following propensity matching. CONCLUSION: Our data showed there is a strong association between using high bicarbonate solution and mortality independent of severity of illness and comorbid conditions. These findings need to be evaluated further in prospective studies.
