“…Access was via internal jugular 6.5-French (Fr) hemodialysis catheters. Mean filter life was 51.1 h. Similar to other studies in pediatric CRRT patients [2-4, 5], fluid overload (FO), defined by the percentage weight gain over weight at admission to the neonatal intensive care unit (NICU), was independently associated with mortality [6]. Neonatal studies have reported an FO of >15-20 % to be associated with poor outcome defined as need for CRRT, prolonged NICU stay, time to extubation or death within 30 days postcardiothoracic surgery [7,8].…”

Neonatal extracorporeal renal replacement therapy—a routine renal support modality?

Peritoneal dialysis (PD) is generally considered the preferred extracorporeal therapy for neonates with acute kidney injury (AKI). However, there are situations when PD is not suitable, such as in patients with previous abdominal surgery, hyperammonemia and significant ascites or anasarca. Additionally, with a need to start PD soon after catheter placement, there is increased risk of PD catheter leak and infection. Extracorporeal continuous renal replacement therapy (CRRT) is challenging in severely ill neonates as it requires obtaining adequately sized central venous access to accommodate adequate blood flow rates and also adaptation of a CRRT machine meant for older children and adults. In addition, ultrafiltration often cannot be set in sufficiently small increments to be suitable for neonates. Although CRRT practices can be modified to fit the needs of infants and neonates, there is a need for a device designed specifically for this population. Until that becomes available, providing the highest level of care for neonates with AKI is dependent on the shared experiences of members of the pediatric nephrology community.Keywords Extracorporeal continuous renal replacement therapy . Acute kidney injury . Neonates . nRIFLE . Continuous venovenous hemodiafiltrationIn a recent article in Pediatric Nephrology, Lee and Cho review their continuous renal replacement therapy (CRRT) experience in 34 neonates with acute kidney injury (AKI) [1]. Although single center and retrospective, there are several noteworthy characteristics of this study. The authors standardize neonatal AKI using the neonatal RIFLE (nRIFLE) criteria to define and stratify severity of AKI. Of the 34 neonates included in the study, 44 % were born preterm (25-36 weeks), with 60 % of these preterm infants being either extremely or very low birth weight. All patients had AKI, and 24 patients met the nRIFLE class F (Failure) criterion. Survival was 50 %. Continuous venovenous hemodiafiltration (CVVHDF) with Prisma or Prismaflex (Gambro/Baxter Int., Lund, Sweden) dialysis machines and M10 (50 ml) or HF20 (55 ml) filters was used for all CRRT treatments. Access was via internal jugular 6.5-French (Fr) hemodialysis catheters. Mean filter life was 51.1 h. Similar to other studies in pediatric CRRT patients [2-4, 5], fluid overload (FO), defined by the percentage weight gain over weight at admission to the neonatal intensive care unit (NICU), was independently associated with mortality [6]. Neonatal studies have reported an FO of >15-20 % to be associated with poor outcome defined as need for CRRT, prolonged NICU stay, time to extubation or death within 30 days postcardiothoracic surgery [7,8]. Interestingly, this study by Lee and Cho [1] reports a much higher FO cut-off of 30 % being associated with poor outcomes, including 100 % mortality for patients reaching an FO of >30 %. The authors propose higher body surface area, calorie consumption and insensible water loss in neonates as a possible explanation. They address this issue by using actual weig...

“…28,29 Numerous observational studies of pediatric patients demonstrated fluid overload was associated with higher mortality. [30][31][32][33] In these studies, fluid overload >10% was associated with higher mortality when controlling for severity of illness. Data from the Prospective Pediatric CRRT Registry Group demonstrated again that % fluid overload was associated with mortality, and that survival was improved (76%) if dry weight was attained during CRRT as compared to those who did not attain dry weight (36%).…”

“…Pediatricians have been at the forefront of identifying fluid overload as a risk factor for mortality in critically ill patients. 80 This is highlighted by the findings of the prospective pediatric continuous renal replacement therapy (CRRT) registry. Sutherland et al 81 showed in a prospective registry of 227 children who were on CRRT that those with a percentage fluid overload ,20% at initiation of renal replacement therapy had improved rates of survival compared with those with a cumulative fluid balance .20% (46% vs 68%, P , .01).…”

In recent years, there have been significant advancements in our understanding of acute kidney injury (AKI) and its impact on outcomes across medicine. Research based on single-center cohorts suggests that neonatal AKI is very common and associated with poor outcomes. In this state-of-the-art review on neonatal AKI, we highlight the unique aspects of neonatal renal physiology, definition, risk factors, epidemiology, outcomes, evaluation, and management of AKI in neonates. The changes in renal function with gestational and chronologic age are described. We put forth and describe the neonatal modified Kidney Diseases: Improving Global Outcomes AKI criteria and provide the rationale for its use as the standardized definition of neonatal AKI. We discuss risk factors for neonatal AKI and suggest which patient populations may warrant closer surveillance, including neonates ,1500 g, infants who experience perinatal asphyxia, near term/ term infants with low Apgar scores, those treated with extracorporeal membrane oxygenation, and those requiring cardiac surgery. We provide recommendations for the evaluation and treatment of these patients, including medications and renal replacement therapies. We discuss the need for long-term follow-up of neonates with AKI to identify those children who will go on to develop chronic kidney disease. This review highlights the deficits in our understanding of neonatal AKI that require further investigation. In an effort to begin to address these needs, the Neonatal Kidney Collaborative was formed in 2014 with the goal of better understanding neonatal AKI, beginning to answer critical questions, and improving outcomes in these vulnerable populations.
