Abstract
Fluid overload is common among pediatric cardiac patients receiving extracorporeal membrane oxygenation (ECMO) and is often treated with in-line ultrafiltration (UF) or continuous renal replacement therapy (CRRT). We assessed whether CRRT was associated with poor outcomes versus UF alone. Additionally, we identified characteristics associated with progression from UF to CRRT. Retrospective chart review of 131 patients age ≤18 years treated with ECMO at a single quaternary center. Data were collected to compare patient demographics, characteristics, and outcomes. A receiver operator curve (ROC) was used to create a tool predictive of the need for CRRT at the time of UF initiation. Patients who required CRRT had a higher creatinine and blood urea nitrogen at time of UF initiation ( p = 0.03 and p < 0.01), longer total ECMO duration ( p < 0.01), lower renal recovery incidence ( p = 0.02), and higher mortality ( p ≤ 0.01). Using ROC analysis, presence of ≤3 of 7 risk variables had a positive predictive value of 87.5% and negative predictive value of 50.0% for use of UF alone (area under the curve 0.801; 95% CI: 0.638-0.965, p = 0.002). Pediatric cardiac patients treated with ECMO and UF who require CRRT demonstrate worse outcomes versus UF alone. A novel clinical tool may assist in stratifying patients at UF initiation.

Effect of a standardized fluid management algorithm on acute kidney injury and mortality in pediatric patients on extracorporeal support. Eur J Pediatr 2023; 182:581-590. [PMID: 36394647 DOI: 10.1007/s00431-022-04699-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 11/03/2022] [Accepted: 11/05/2022] [Indexed: 11/18/2022]
Abstract
Acute kidney injury (AKI), fluid overload (FO), and mortality are common in pediatric patients supported by extracorporeal membrane oxygenation (ECMO). The aim of this study is to evaluate if using a fluid management algorithm reduced AKI and mortality in children supported by ECMO. We performed a retrospective study of pediatric patients aged birth to 25 years requiring ECMO at a quaternary level children's hospital from 2007 to 2019 In October 2017, a fluid management algorithm was implemented for protocolized fluid removal after deriving a daily fluid goal using a combination of diuretics and ultrafiltration. Daily algorithm compliance was defined as ≥ 12 h on the algorithm each day. The primary and secondary outcomes were AKI and mortality, respectively, and were assessed in the entire cohort and the sub-analysis of children from the era in which the algorithm was implemented. Two hundred and ninety-nine (median age 5.3 months; IQR: 0.2, 62.3; 45% male) children required ECMO (venoarterial in 85%). The fluid algorithm was applied in 74 patients. The overall AKI rate during ECMO was 38% (26% severe-stage 2/3). Both AKI incidence and mortality were significantly lower in patients managed on the algorithm (p = 0.02 and p = 0.05). After adjusting for confounders, utilization of the algorithm was associated with lower odds of AKI (aOR: 0.40, 95%CI: 0.21, 0.76; p = 0.005) but was not associated with a reduction in mortality. In the sub-analysis, algorithm compliance of 80-100% was associated with a 54% reduction in mortality (ref: < 60% compliant; aOR:0.46, 95%CI:0.22-1.00; p = 0.05). Conclusion: Among the entire cohort, the use of a fluid management algorithm reduced the odds of AKI. Better compliance on the algorithm was associated with lower mortality. Multicenter studies that implement systematic fluid removal may represent an opportunity for improving ECMO-related outcomes. What is Known: • Acute kidney injury and fluid overload are associated with morbidity and mortality in children supported by extracorporeal membrane oxygenation. What is New: • A systematic and protocolized approach to fluid removal in children supported by extracorporeal membrane oxygenation reduces acute kidney injury incidence. • Greater adherence to a protocolized fluid removal algorithm is associated with a reduction in mortality.

Abstract
Extracorporeal membrane oxygenation (ECMO) is a form of cardiopulmonary support primarily used in cardiothoracic and intensive care unit (ICU) settings. The purpose of this review is to familiarise radiologists with the imaging features of ECMO devices, their associated complications and appropriate imaging protocols for contrast-enhanced CT imaging of ECMO patients. This paper will provide a brief introduction to ECMO and the imaging modalities utilised in ECMO patients, followed by a description of the types of ECMO available and cannula positioning. Indications and contraindications for ECMO will be outlined followed by a description of the complications associated with ECMO, which radiologists should recognise. Finally, the imaging protocol and interpretation of contrast-enhanced CT imaging in ECMO patients will be discussed. In the current clinical climate with millions of COVID-19 cases around the world and tens of thousands of critically ill patients, many requiring cardiopulmonary support in intensive care units, the use of ECMO in adults has increased, and thus so has the volume of imaging. Radiologists need to be familiar with the types of ECMO available, the correct positioning of the catheters depending on the type of ECMO being utilised, and the associated complications and imaging artefacts.

Fluid overload and fluid removal in pediatric patients on extracorporeal membrane oxygenation requiring continuous renal replacement therapy: a multicenter retrospective cohort study. Pediatr Nephrol 2020; 35:871-882.

Abstract
OBJECTIVE The aim of this study was to characterize continuous renal replacement therapy (CRRT) utilization on extracorporeal membrane oxygenation (ECMO) and to determine the association of both fluid overload (FO) at CRRT initiation and fluid removal during CRRT with mortality in a large multicenter cohort. METHODS Retrospective chart review of all children < 18 years of age concurrently treated with ECMO and CRRT from January 1, 2007, to December 31, 2011, at six tertiary care children's hospital. Children treated with hemodialysis or peritoneal dialysis were excluded from the FO analysis. MEASUREMENTS AND MAIN RESULTS A total of 756 of the 1009 children supported with ECMO during the study period had complete FO data. Of these, 357 (47.2%) received either CRRT or were treated with an in-line filter and thus entered into the final analysis. Survival to ECMO decannulation was 66.4% and survival to hospital discharge was 44.3%. CRRT initiation occurred at median of 1 day (IQR 0, 2) after ECMO initiation. Median FO at CRRT initiation was 20.1% (IQR 5, 40) and was significantly lower in ECMO survivors vs. non-survivors (15.3% vs. 30.5% p = 0.005) and in hospital survivors vs. non-survivors (13.5% vs. 25.9%, p = 0.004). Median FO at CRRT discontinuation was significantly lower in ECMO survivors (23% vs. 37.6% p = 0.002) and hospital survivors vs. non-survivors (22.6% vs. 36.1%, p = 0.002). In ECMO survivors, after adjusting for pH at CRRT initiation, non-renal complications, ECMO mode, support type, center, patient age and AKI, FO at CRRT initiation (p = 0.01), and FO at CRRT discontinuation (p = 0.0002) were independently associated with duration of ECMO. In a similar multivariable analysis, FO at CRRT initiation (adjusted adds ratio [aOR] 1.09, 95% CI 1.00-1.18, p = 0.045) and at CRRT discontinuation (aOR 1.11, 95% CI 1.03-1.19, p = 0.01) were independently associated with hospital mortality. CONCLUSIONS In a multicenter pediatric ECMO cohort, this study demonstrates that severe FO was very common at CRRT initiation. We found an independent association between the degree of FO at CRRT initiation with adverse outcomes including mortality and increased duration of ECMO support. The results suggest that intervening prior to the development of significant FO may be a clinical therapeutic target and warrants further evaluation.

Abstract
Oxidative stress is a frequent condition in critically ill patients, especially if exposed to extracorporeal circulation, and it is associated with worse outcomes and increased mortality. The inflammation triggered by the contact of blood with a non-endogenous surface, the use of high volumes of packed red blood cells and platelets transfusion, the risk of hyperoxia and the impairment of antioxidation systems contribute to the increase of reactive oxygen species and the imbalance of the redox system. This is responsible for the increased production of superoxide anion, hydrogen peroxide, hydroxyl radicals, and peroxynitrite resulting in increased lipid peroxidation, protein oxidation, and DNA damage. The understanding of the pathophysiologic mechanisms leading to redox imbalance would pave the way for the future development of preventive approaches. This review provides an overview of the clinical impact of the oxidative stress during neonatal extracorporeal support and concludes with a brief perspective on the current antioxidant strategies, with the aim to focus on the potential oxidative stress-mediated cell damage that has been implicated in both short and long-term outcomes.

Abstract
OBJECTIVE To characterize the epidemiology of fluid overload and its association with mortality and duration of extracorporeal membrane oxygenation in children treated with extracorporeal membrane oxygenation. DESIGN Retrospective cohort study. SETTING Six tertiary children's hospital ICUs. PATIENTS Seven hundred fifty-six children younger than 18 years old treated with extracorporeal membrane oxygenation for greater than or equal to 24 hours from January 1, 2007, to December 31, 2011. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Overall survival to extracorporeal membrane oxygenation decannulation and hospital discharge was 74.9% (n = 566) and 57.7% (n = 436), respectively. Median fluid overload at extracorporeal membrane oxygenation initiation was 8.8% (interquartile range, 0.3-19.2), and it differed between hospital survivors and non survival, though not between extracorporeal membrane oxygenation survivors and non survivors. Median peak fluid overload on extracorporeal membrane oxygenation was 30.9% (interquartile range, 15.4-54.8). During extracorporeal membrane oxygenation, 84.8% had a peak fluid overload greater than or equal to 10%; 67.2% of patients had a peak fluid overload of greater than or equal to 20% and 29% of patients had a peak fluid overload of greater than or equal to 50%. The median peak fluid overload was lower in patients who survived on extracorporeal membrane oxygenation (27.2% vs 44.4%; p < 0.0001) and survived to hospital discharge (24.8% vs 43.3%; p < 0.0001). After adjusting for acute kidney injury, pH at extracorporeal membrane oxygenation initiation, nonrenal complications, extracorporeal membrane oxygenation mode, support type, center and patient age, the degree of fluid overload at extracorporeal membrane oxygenation initiation (p = 0.05), and the peak fluid overload on extracorporeal membrane oxygenation (p < 0.0001) predicted duration of extracorporeal membrane oxygenation in survivors. Multivariable analysis showed that peak fluid overload on extracorporeal membrane oxygenation (adjusted odds ratio, 1.09; 95% CI, 1.04-1.15) predicted mortality on extracorporeal membrane oxygenation; fluid overload at extracorporeal membrane oxygenation initiation (adjusted odds ratio, 1.13; 95% CI, 1.05-1.22) and peak fluid overload (adjusted odds ratio, 1.18; 95% CI, 1.12-1.24) both predicted hospital morality. CONCLUSIONS Fluid overload occurs commonly and is independently associated with adverse outcomes including increased mortality and increased duration of extracorporeal membrane oxygenation in a broad pediatric extracorporeal membrane oxygenation population. These results suggest that fluid overload is a potential target for intervention to improve outcomes in children on extracorporeal membrane oxygenation.

Abstract
OBJECTIVE In a population of neonatal and pediatric patients on extracorporeal membrane oxygenation; to describe the prevalence and timing of acute kidney injury utilizing a consensus acute kidney injury definition and investigate the association of acute kidney injury with outcomes (length of extracorporeal membrane oxygenation and mortality). DESIGN Multicenter retrospective observational cohort study. SETTING Six pediatric extracorporeal membrane oxygenation centers. PATIENTS Pediatric patients (age, < 18 yr) on extracorporeal membrane oxygenation at six centers during a period of January 1, 2007, to December 31, 2011. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Complete data were analyzed for 832 patients on extracorporeal membrane oxygenation. Sixty percent of patients had acute kidney injury utilizing the serum creatinine Kidney Disease Improving Global Outcomes criteria (AKI) and 74% had acute kidney injury using the full Kidney Disease Improving Global Outcomes criteria including renal support therapy (AKI). Of those who developed acute kidney injury, it was present at extracorporeal membrane oxygenation initiation in a majority of cases (52% AKI and 65% AKI) and present by 48 hours of extracorporeal membrane oxygenation support in 86% (AKI) and 93% (AKI). When adjusted for patient age, center of support, mode of support, patient complications and preextracorporeal membrane oxygenation pH, the presence of acute kidney injury by either criteria was associated with a significantly longer duration of extracorporeal membrane oxygenation support (AKI, 152 vs 110 hr; AKI, 153 vs 99 hr) and increased adjusted odds of mortality at hospital discharge (AKI: odds ratio, 1.77; 1.22-2.55 and AKI: odds ratio, 2.50; 1.61-3.90). With the addition of renal support therapy to the model, acute kidney injury was associated with a longer duration of extracorporeal membrane oxygenation support (AKI, 149 vs 121 hr) and increased risk of mortality at hospital discharge (AKI: odds ratio, 1.52; 1.04-2.21). CONCLUSION Acute kidney injury is present in 60-74% of neonatal-pediatric patients supported on extracorporeal membrane oxygenation and is present by 48 hours of extracorporeal membrane oxygenation support in 86-93% of cases. Acute kidney injury has a significant association with increased duration of extracorporeal membrane oxygenation support and increased adjusted odds of mortality at hospital discharge.

Abstract
The use of renal replacement therapy (RRT) in patients receiving extracorporeal membrane oxygenation (ECMO) is increasing, but the effect of RRT on ECMO is controversial. We performed a meta-analysis to determine whether RRT is related to higher mortality in patients receiving ECMO. We searched MEDLINE, EMBASE, the Cochrane Library, and KoreaMed and found 43 observational studies with 21,624 patients receiving ECMO and then compared inpatient mortality rates of patients receiving ECMO both with and without RRT. The risk ratio (RR) of mortality between patients receiving RRT and those not receiving RRT tended to decrease as the mortality of the group not receiving RRT increased. Among patients with RRT use rates of 30% and higher, the overall mortality rates for all patients receiving ECMO tended to decrease. We found that the increase in the RR for RRT tended to be greater the longer the initiation of RRT was delayed. We suggest that in patients receiving ECMO who have high RRT use rates, RRT may decrease mortality rates.

Abstract
Background: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is utilized for cardiopulmonary failure. We aimed to qualify and quantify the predictors of morbidity and mortality in infants requiring VA-ECMO. Methods: Data was collected from 170 centers participating in the extracorporeal life support organization (ELSO) registry. Relationships between in-hospital mortality and risk factors were assessed using logistic regression. Survival was defined as being discharged from the hospital. Results: Six hundred and sixty-two eligible records were reviewed. Mortality occurred in 303 (46%) infants. Congenital diaphragmatic hernia patients (OR=3.83, 95% CI 1.96-7.49, p<0.001), cardiac failure with associated shock (OR= 2.90, 95% CI 1.46-5.77, p=0.002), and pulmonary failure including respiratory distress syndrome (OR=4.06, 95% CI 1.72-9.58, p=0.001) had the highest odds of mortality in this cohort. Birth weight (BW) < 3 kg (OR=1.83, 95% CI 1.21-2.78, p=0.004), E-CPR (OR=3.35, 95% CI 1.57-7.15, p=0.002), hemofiltration (OR=2.04, 95% CI 1.32-3.16, p=0.001), and dialysis (OR=6.13, 95% CI 1.70-22.1, p<0.001) were all independent predictors of mortality. Conclusion: Infants requiring VA-ECMO experience diverse sequelae and their mortality are high.

Abstract
Critically ill neonates are at risk for acute kidney injury (AKI). AKI has been associated with increased risk of morbidity and mortality in adult and pediatric patients, and increasing evidence suggests a similar association in the neonatal population. This article describes the current AKI definitions (including their limitations), work on novel biomarkers to define AKI, diagnosis and management strategies, long-term outcomes after AKI, and future directions for much-needed research in this important area.

Abstract
Overwhelming adenovirus infection requiring extracorporeal membrane oxygenation (ECMO) support carries a high mortality in pediatric patients. The objective of this study was to retrospectively review data from the Extracorporeal Life Support Organization (ELSO) registry for pediatric patients with adenovirus infection and define for this patient cohort: 1) clinical characteristics, 2) survival to hospital discharge, and 3) factors associated with mortality before hospital discharge. In this retrospective registry study, pediatric patients with adenovirus infection requiring ECMO support identified in an international ECMO registry from 1998 to 2009 were compared for clinical characteristics (demographics, pre-ECMO variables, and complications on ECMO) between survivors and nonsurvivors to hospital discharge. Descriptive statistics and univariate and multivariate logistic analysis were used to compare clinical characteristics among survivors and nonsurvivors. For children requiring ECMO support for adenovirus, the survival at hospital discharge is 38% (62/163). Among neonates (<31 days of age), the survival at hospital discharge was only 11% (6/54). Among patient factors, neonatal age (odds ratio [OR], 4.3; 95% confidence interval [CI], 1.62-10.87), a decrease of 0.1 unit in pre-ECMO pH (OR, 1.77; 95% CI, 1.3-2.42), the presence of sepsis (OR, 4.55; 95% CI, 1.47-14.15), and increased peak inspiratory pressures (OR, 1.04; 95% CI, 1.01-1.08) were all independently associated with in-hospital mortality. ECMO complications independently associated with in-hospital mortality were presence of pneumothorax (OR, 3.57; 95% CI, 1.19-10.7), pH less than 7.2 (OR, 5.94; 95% CI, 1.04-34.1), and central nervous system hemorrhage (OR, 25.36; 95% CI, 1.47-436.7). In this retrospective cohort study of pediatric patients with adenovirus infection supported on ECMO, survival to hospital discharge was 38% but was much lower in neonates. Neonatal presentation, degree of acidosis, sepsis, and increased PIP are factors present before decisions are made regarding a trial of ECMO, whereas pneumothorax and brain hemorrhage were ECMO-related complications independently associated with mortality.

Abstract
OBJECTIVE In pediatric patients, fluid overload at continuous renal replacement therapy initiation is associated with increased mortality. The aim of this study was to characterize the association between fluid overload at continuous renal replacement therapy initiation, fluid removal during continuous renal replacement therapy, the kinetics of fluid removal and mortality in a large pediatric population receiving continuous renal replacement therapy while on extracorporeal membrane oxygenation. DESIGN Retrospective chart review. SETTING Tertiary children's hospital. PATIENTS Extracorporeal membrane oxygenation patients requiring continuous renal replacement therapy from July 2006 to September 2010. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Overall intensive care unit survival was 34% for 53 patients that were initiated on continuous renal replacement therapy while on extracorporeal membrane oxygenation during the study period. Median fluid overload at continuous renal replacement therapy initiation was significantly lower in survivors compared to nonsurvivors (24.5% vs. 38%, p = .006). Median fluid overload at continuous renal replacement therapy discontinuation was significantly lower in survivors compared to nonsurvivors (7.1% vs. 17.5%, p = .035). After adjusting for percent fluid overload at continuous renal replacement therapy initiation, age, and severity of illness, the change in fluid overload at continuous renal replacement therapy discontinuation was not significantly associated with mortality (p = .212). Models investigating the rates of fluid removal in different periods, age, severity of illness, and fluid overload at continuous renal replacement therapy initiation found that fluid overload at continuous renal replacement therapy initiation was the most consistent predictor of survival. CONCLUSIONS Our data demonstrate an association between fluid overload at continuous renal replacement therapy initiation and mortality in pediatric patients receiving extracorporeal membrane oxygenation. The degree of fluid overload at continuous renal replacement therapy discontinuation is also associated with mortality, but appears to reflect the effect of fluid overload at initiation. Furthermore, correction of fluid overload to ≤ 10% was not associated with improved survival. These results suggest that intervening prior to the development of significant fluid overload may be more clinically effective than attempting fluid removal after significant fluid overload has developed. Our findings suggest a role for earlier initiation of continuous renal replacement therapy in this population, and warrant further clinical studies.

Abstract
Acute kidney injury and fluid overload (FO) are associated with increased mortality in critically ill patients, including the subset supported with extracorporeal membrane oxygenation (ECMO). The indication for and method of application of renal support therapy (RST) during ECMO is largely unknown beyond single-center experiences. The current study uses a survey design to document practice variation regarding RST, including indication, method of interface with the ECMO circuit, and prescribing practices. Sixty-five international ECMO centers (31%) responded to an online electronic survey regarding RST during ECMO. Nearly a quarter of centers (23%) reported using no RST during ECMO. Among those using the therapy, the predominant mode of therapy applied was convection and included slow continuous ultrafiltration and continuous venovenous hemofiltration. The predominant indication for RST was the treatment (43%) or prevention (16%) of FO. Nephrology rather than critical care medicine is reported as the prescribing service in a majority of centers with a significant difference between US centers and non-US centers. The results of this study identify a wide variation in practice regarding RST during ECMO that will offer multiple important avenues for further research by this group and others regarding the interface of RST and ECMO.

Abstract
OBJECTIVE To assess the outcome of pediatric patients supported by concomitant extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT). DESIGN, SETTING, AND PATIENTS Acute kidney injury is associated with mortality in ECMO patients. CRRT in patients on ECMO provides an efficient and potentially beneficial method of acute kidney injury management. Concern that concomitant CRRT use increases the risk of developing anuria and chronic renal failure limits its use in some centers. We hypothesized that development of chronic renal failure is rare with concurrent ECMO and CRRT. We evaluated the outcomes of 154 ECMO/CRRT patients cared for over 10 yrs at a referral pediatric medical center. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Among 68 (44%) ECMO/CRRT survivors, 45 were assigned a pediatric risk, injury, failure, loss and end-stage (referred to as "pRIFLE") score at CRRT initiation. Seventeen (38%) patients met the criteria for Risk, 15 (33%) for Injury, and 10 (22%) for Failure. Two Failure patients later met End stage criteria. Of all survivors, 18 (26%) required ongoing renal replacement therapy (15 required continuous veno-venous hemofiltration, two required peritoneal dialysis, and one patient required intermittent hemodialysis) post ECMO discontinuation. Renal recovery occurred in 65 (96%) of 68 patients before discharge. One neonatal patient had sepsis-induced renal injury on transfer, but had normal creatinine 1 month later. Two pediatric patients with vasculitis and primary renal disease at presentation (both meeting Failure criteria) developed end-stage renal disease. One received peritoneal dialysis and subsequent renal transplant. The other has diminished function without need for renal replacement therapy. CONCLUSION In the absence of primary renal disease, chronic renal failure did not occur after concurrent use of CRRT with ECMO. Concern for precipitating chronic renal failure by using CRRT during ECMO is not substantiated by this large single-center experience. Consistent with previous reports, mortality is higher in patients receiving concomitant CRRT and ECMO compared with those receiving ECMO alone. Mortality is similar to patients requiring CRRT who are not on ECMO. Additional studies are warranted to determine the optimal role of CRRT use in ECMO patients.

Abstract
OBJECTIVE To determine the independent impact of acute kidney injury (AKI) and renal replacement therapy (RRT) in infants and children who receive extracorporeal membrane oxygenation. Despite continued expertise/technological advancement, patients who receive extracorporeal membrane oxygenation have high mortality. AKI and RRT portend poor outcomes independent of comorbidities and illness severity in several critically ill populations. DESIGN Retrospective cohort study. The primary variables explored are AKI (categorical complication code for serum creatinine > 1.5 mg/dL or International Statistical Classification of Diseases and Related Health Problems, Revision 9 for acute renal failure), and RRT (complication/Current Procedural Terminology code for dialysis or hemofiltration). Multiple variables previously associated with mortality in this population were controlled, using logistic stepwise regression. Decision tree modeling was performed to determine optimal variables and cut points to predict mortality. PATIENTS Critically ill neonates (0-30 days old) and children (> 30 days but < 18 yrs old) in the Extracorporeal Life Support Organization registry. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Neonatal mortality was 2175 (27.4%) of 7941. Nonsurvivors experienced more AKI (413 [19%] of 2175 vs. 225 [3.9%] of 5766, p < .0001), and more received RRT (863 [39.7%] of 2175 vs. 923 [16.0%] of 5766, p < .0001) than survivors. Pediatric mortality was 816 (41.6%) of 1962. Pediatric nonsurvivors similarly experienced more AKI (264 [32.3%] of 816 vs. 138 [12.0%] of 1146, p < .0001) and RRT (487 [58.9%] of 816 vs. 353 [30.8%] of 1146, p < .0001) than survivors. After adjusting for confounding variables, the adjusted odds ratio for neonatal group was 3.2 (p < .0001) post AKI and 1.9 (p < .0001) given RRT. Similarly, the pediatric adjusted odds ratio for mortality was 1.7 (p < .001) post AKI and 2.5 (p < .0001) given RRT. AKI and RRT were essential in the neonatal and pediatric mortality decision trees. CONCLUSIONS After adjusting for known predictors of mortality, AKI and RRT independently predict mortality in neonates and children, who receive extracorporeal membrane oxygenation. Ascertainment of AKI risk factors, testing novel therapies, and optimizing the timing/delivery of RRT may positively impact survival.

Abstract
OBJECTIVE: To determine variables associated with survival in pediatric patients treated with hemofiltration while receiving extracorporeal life support and to determine the probability for recovery of renal function among survivors. DESIGN: Retrospective database analysis. SETTING: University of Michigan pediatric nephrology database. PATIENTS: All pediatric patients treated with continuous hemofiltration while on extracorporeal life support at the University of Michigan between January 1990 and May 1999. A pediatric patient was defined as any child between birth and 18 yrs of age, including children treated in both the pediatric intensive care unit and neonatal intensive care unit. Indications for extracorporeal life support included both cardiac and pulmonary failure. INTERVENTIONS: Data analysis of patients who were treated with hemofiltration while on extracorporeal life support. Hemofiltration includes both ultrafiltration and hemofiltration with countercurrent dialysis. MEASUREMENTS AND MAIN RESULTS: Thirty-five patients with a mean age of 39 +/- 65 months (median, 3 months) underwent hemofiltration while on extracorporeal life support. Forty-three percent survived to hospital discharge (95% CI, 26%-60%). All deaths occurred in the intensive care unit. Recovery of renal function occurred in 93% of survivors (95% CI, 79%-108%). Mean duration of hemofiltration in survivors, including time during and after extracorporeal life support, was 9 +/- 6 days. All nonsurvivors were on renal replacement therapy at the time of death. In this analysis, decreased survival was significantly associated with the use of vasopressor infusions (p =.01) and the presence of complications (p =.006). Vasopressor infusions were required in 89% of patients, and 37% of patients experienced complications. CONCLUSIONS: In patients receiving hemofiltration while on extracorporeal life support, survival is comparable to that reported in other extracorporeal life support or hemofiltration populations. Decreased survival in these patients may be associated with the use of vasopressor infusions and the occurrence of complications. Recovery of renal function occurs in most survivors.

Abstract
BACKGROUND/PURPOSE The purpose of this study was to evaluate the evolving outcome of newborns who have congenital diaphragmatic hernia (CDH) using a protocolized approach to management, which includes extracorporeal membrane oxygenation (ECMO) and to present the details of such a management protocol. METHODS A retrospective chart review was conducted of the neonatal outcome of near-term (>34 weeks' gestation) newborns with CDH all referred to the Royal Alexandra Hospital either before or after delivery. A protocol was developed that included antenatal assessment, the use of antenatal steroids, planned delivery, use of prophylactic surfactant, pressure limited gentle ventilation, permissive hypercarbia and hypoxia, and venovenous ECMO, if indicated. RESULTS Sixty-five infants with CDH were treated from February 1989 through August 1996. Twenty-three infants were inborn, 20 of whom were antenatal referrals. Overall, 51 of the 65 infants survived (78%). Thirteen of the 23 inborn infants survived with conservative management, and 10 required ECMO, of whom, eight were long-term survivors. Thirty-eight infants required ECMO, and 26 survived (68%), whereas there were only two deaths among the 27 conservatively treated infants. Eighteen of 20 inborn infants with an antenatal diagnosis survived, compared with 13 of 21 (62%) outborn infants. An antenatal diagnosis before 25 weeks' gestation was associated with a 60% survival rate. Sixty-three percent of infants whose best postductal PaO2 value before ECMO was less than 100 torr survived, and 7 of 11 infants with a best postductal PaO2 value of less than 50 torr before ECMO survived (64%). The average age at surgery progressively increased over time both for infants who did not require ECMO (1.3 days to 5.8 days; P = .01) and for infants who received ECMO (1.9 days to 8.2 days; P = .016). CONCLUSIONS The use of a protocolized management for infants with CDH has been associated with improving outcome in a population at high risk. The components (either separately or combined) of these protocolized approaches need to be tested in prospective trials to determine their true benefit. In addition, there is a need to evaluate prospectively the outcomes of infants with CDH born in ECMO centers compared with those infants born in other tertiary care neonatal units to determine the most appropriate management of the fetus with CDH.

Abstract
BACKGROUND/PURPOSE Cardiopulmonary resuscitation (CPR) is reported to be used in a significant number of neonates before initiation of extracorporeal membrane oxygenation (ECMO). This report establishes the incidence of infants who require CPR before initiation of ECMO and elucidates survival rates and long-term neurological outcomes. In addition, the authors sought prognostic factors that could reliably predict survival or long-term neurological outcome before initiating ECMO support. METHODS The Extracorporeal Life Support Organization (ELSO) registry provided data on 839 neonates who received CPR before ECMO from January 1989 to April 1995. Supplemental questionnaires on 414 infants were returned from 64 ECMO centers regarding details of the CPR event and subsequent neurological development. One-year neurological evaluations were provided on 112 infants. Data were analyzed for statistical significance using chi2, multiple logistic regression, and Kruskal Wallis one-way analysis of variance as applicable, with significance set at P < .05. RESULTS The incidence of infants requiring pre-ECMO CPR was 13.1%. Infants who received pre-ECMO CPR had a survival rate of 60.8% versus 81.6% survival for infants who did not require CPR (P < .00001). Analysis of ELSO registry data showed survival was significantly associated with primary diagnosis, location of CPR, last pH level before ECMO, and the presence of intraventricular hemorrhage. Questionnaire data on 12-month neurological assessment showed 63% had no impairment and 4% were graded as severely impaired. Twelve-month neurological outcome was significantly associated only with primary diagnosis. CONCLUSION A survival rate of 60.8% with good neurological outcome at 12 months in 63.4% of infants suggests that CPR alone should not be a contraindication to placing a neonate on ECMO.

Abstract
Extracorporeal membrane oxygenation (ECMO) is an important means of supporting newborns with respiratory failure. While short- and long-term follow-up of ECMO survivors has been thoroughly addressed, there is no systematic study of nonsurvivors. Nineteen nonsurvivors of newborn ECMO with autopsy results are divided into two groups: group 1: 12 patients who had intracranial lesions as the primary cause of death (hemorrhage 8, encephalomalacia 2, infarct 2); and group 2: 7 patients with nonintracranial primary causes of death. Patients in group 1 were significantly more acidotic, hypotensive, and smaller in age and birth weight pre-ECMO. Among group 2 patients, two with diaphragmatic hernia died of primary pulmonary disease (diffuse alveolar damage, pulmonary hypoplasia and necrosis, bronchopneumonia). One of 2 patients with persistent fetal circulation (PFC) was treated with massive doses of tolazoline and suffered fatal gastrointestinal hemorrhage and ischemic necrosis of heart, spleen, testes, and adrenals. The other PFC patient had severe pulmonary interstitial fibrosis. Two patients with meconium aspiration and a patient with streptococcal sepsis had diffuse pulmonary damage and multiple organ failure (renal medullary necrosis, and infarcts of adrenal, spleen, liver). In this series, intracranial pathology was the most common cause of death in ECMO patients, related to gestational age, acidosis, hypoxia, and size, but probably unrelated to carotid ligation.
