A large percentage of patients on extracorporeal membrane oxygenation (ECMO) require continuous renal replacement therapy (CRRT) usually performed through a different venous access or by introducing a filter into the ECMO circuit. Here, we evaluated the efficacy and safety of including a CRRT machine in the circuit by connecting its inlet line after the centrifugal pump and its outlet line before the oxygenator. We tested the function of the combined system initially in a closed circuit, followed by an experimental animal study, and, finally, in a clinical trial with six children. Both machines functioned adequately and there were no significant changes in the pressures of the ECMO circuit after the introduction of the CRRT device, thus achieving the preset negative balances and normalization of the serum urea and creatinine concentrations. The mean life of the filters was about 138 h, and only one filter needed changing due to clotting. Our study shows that the introduction of a CRRT device into the ECMO circuit is a safe and effective technique that improves fluid balance, increases filter life, and does not cause complications. For these reasons, this may be a good method for performing CRRT in patients on ECMO.

The Pediatric Task Force reviewed all questions submitted by the International Liaison Committee on Resuscitation (ILCOR) member councils in 2010, reviewed all council training materials and resuscitation guidelines and algorithms, and conferred on recent areas of interest and controversy. We identified a few areas where there were key differences in council-specific guidelines based on historical recommendations, such as the A-B-C (Airway, Breathing, Circulation) versus C-A-B (Circulation, Airway, Breathing) sequence of provision of cardiopulmonary resuscitation (CPR), initial back blows versus abdominal thrusts for foreign-body airway obstruction, an upper limit for recommended chest compression rate, and initial defibrillation dose for shockable rhythms (2 versus 4 J/kg). We produced a working list of prioritized questions and topics, which was adjusted with the advent of new research evidence. This led to a prioritized palate of 21 PICO (population, intervention, comparator, outcome) questions for ILCOR task force focus.The 2015 process was supported by information specialists who performed in-depth systematic searches, liaising with pediatric content experts so that the most appropriate terms and outcomes and the most relevant publications were identified. Relevant adult literature was considered (extrapolated) in those PICO questions that overlapped with other task forces, or when there were insufficient pediatric data. In rare circumstances (in the absence of sufficient human data), appropriate animal studies were incorporated into reviews of the literature. However, these data were considered only when higher levels of evidence were not available and the topic was deemed critical.When formulating the PICO questions, the task force felt it important to evaluate patient outcomes that extend beyond return of spontaneous circulation (ROSC) or discharge from the pediatric intensive care unit (PICU). In recognition that the measures must have meaning, not only to clinicians but also to parents and caregivers, longer-term outcomes at 30 days, 60 days, 180 days, and 1 year with favorable neurologic status were included in the relevant PICO questions.Each task force performed a detailed systematic review based on the recommendations of the Institute of Medicine of the National Academies 1 and using the methodological approach proposed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) working group.2 After identifying and prioritizing the questions to be addressed (by using the PICO format) 3 with the assistance of information specialists, a detailed search for relevant articles was performed in each of 3 online databases (PubMed, Embase, and the Cochrane Library).By using detailed inclusion and exclusion criteria, articles were screened for further evaluation. The reviewers for each question created a reconciled risk-of-bias assessment for each of the included studies, using state-of-the-art tools: Cochrane for randomized controlled trials (RCTs), 4 Quality Assessment of Diagnosti...
