Introduction: Extracorporeal Membrane Oxygenation (ECMO) is utilized in the management of severe respiratory and circulatory failure. Advanced malignancy is a relative contraindication but the indication for ECMO in the oncologic population has not been clearly established due to the wide spectrum of malignant disease and prognoses. Hypothesis: ECMO is a feasible treatment modality in selected adult oncologic population. Method: The Extracorporeal Life Support Organization (ELSO) database was queried for patients older than 18 years with an International Classification of Diseases (ICD) code of neoplasm over the past two decades (2000-2019). The data were divided into two decades to analyze and compare the trends with background and outcomes. Results: One thousand, six hundred, and ninety-seven patients met inclusion criteria from the last decade which is more than 15 times the number from the previous decade (n=110). Compared with the previous decade, ECMO was used more in patients with older age (56 vs 50.5 years old; p<0.001), cardiac and extracorporeal cardiopulmonary resuscitation (ECPR) support type (p = 0.001), higher P/F ratio (79.0 vs 61.8; p=0.001), and lower oxygenation index (23.0 vs 35.6; p< 0.001) in the last decade. Although survival did not show significant improvement overall (38.9% [660 of 1697] vs 33.6% [37 of 110]; p=0.272), survival in pulmonary ECMO has significantly improved in the last decade (41.6% [409 of 983] vs 29.1% [23 of 79]; p=0.030). Diagnosis of hematologic malignancy, ECPR, and hematopoietic stem cell transplant were identified as predictors of poor prognosis (p = 0.025, <0.001, and 0.021 respectively). Conclusion: Utilization of ECMO for patients with neoplasms has increased over time mirroring the overall increase of adult ECMO. With careful patient selection, ECMO can be successful in oncologic population.

Introduction: Respiratory failure is the leading cause of mortality in individuals with congenital spine and rib deformities. We present a case report of a child with Jeune syndrome surviving respiratory failure using extracorporeal membrane oxygenation (ECMO). We also summarize thoracic insufficiency syndrome cases reported in the Extracorporeal Life Support Organization (ELSO) registry. Case Report: A two-year-old male with a chest circumference less than a third percentile for age was admitted with influenza pneumonia developing a peak oxygenation index of 103.5. The child survived to baseline pulmonary function after nine days of venous-arterial ECMO support. Discussion: The ELSO registry contained 27 individuals with a surrogate diagnosis of thoracic insufficiency (0.05%). There was no significant difference in survival to discharge for thoracic insufficiency patients (52%) compared to a previously healthy population supported with ECMO. Conclusion: ECMO is safe and may be effective in supporting individuals with thoracic insufficiency.

Background: Anticoagulation monitoring practices vary during extracorporeal membrane oxygenation (ECMO). The Extracorporeal Life Support Organization describes that a multimodal approach is needed to overcome assay limitations and minimize complications. Objective: Compare activated clotting time (ACT) versus multimodal approach (activated partial thromboplastin time (aPTT)/anti-factor Xa) for unfractionated heparin (UFH) monitoring in adult ECMO patients. Methods: We conducted a single-center retrospective pre- (ACT) versus post-implementation (multimodal approach) study. The incidence of major bleeding and thrombosis, blood product and antithrombin III (ATIII) administration, and UFH infusion rates were compared. Results: Incidence of major bleeding (69.2% versus 62.2%, p = 0.345) and thrombosis (23% versus 14.9%, p = 0.369) was similar between groups. Median number of ATIII doses was reduced in the multimodal group (1.0 [IQR 0.0-2.0] versus 0.0 [0.0 -1.0], p = 0.007). The median UFH infusion rate was higher in the ACT group, but not significant (16.9 [IQR 9.6-22.4] versus 13 [IQR 9.6-15.4] units/kg/hr, p = 0.063). Fewer UFH infusion rate changes occurred prior to steady state in the multimodal group (0.9 [IQR 0.3 -1.7] versus 0.1 [IQR 0.0-0.2], p < 0.001). Conclusion: The incidence of major bleeding and thrombosis was similar between groups. Our multimodal monitoring protocol standardized UFH infusion administration and reduced ATIII administration.

Introduction: Pediatric patients with hemophagocytic lymphohistiocytosis (HLH) may develop refractory respiratory or cardiac failure that warrants consideration for extracorporeal membrane oxygenation (ECMO) support. The purposes of this study were to describe the use and outcomes of ECMO in pediatric HLH patients, to identify risk factors for hospital mortality and to compare their ECMO use and outcomes to the ECMO population as a whole. Methods: Pediatric patients (⩽ 18 years) with a diagnosis of HLH in the Extracorporeal Life Support Organization (ELSO) Registry were included. Results: Between 1983 and 2014, data for 30 children with HLH were available in the ELSO registry and all were included in this study. All cases occurred in the last decade. Of the 30 HLH patients, 24 (80%) had a respiratory indication for ECMO and six (20%) had a cardiac indication (of which 4 were E-CPR and 2 cardiac failure). Of the 24 respiratory ECMO patients, 63% were placed on VA ECMO. Compared with all pediatric patients in the ELSO registry during the study period (n=17,007), HLH patients had worse hospital survival (non-HLH 59% vs HLH 30%, p=0.001). In pediatric HLH patients, no pre-ECMO risk factors for mortality were identified. The development of a hemorrhagic complication on ECMO was associated with decreased mortality (p=0.01). Comparing HLH patients with respiratory failure to patients with other immune compromised conditions, the overall survival rate is similar (HLH 38% vs. non-HLH immune compromised 31%, p=0.64). Conclusions: HLH is an uncommon indication for ECMO and these patients have increased mortality compared to the overall pediatric ECMO population. These data should be factored into decision-making when considering ECMO for pediatric HLH patients.

AbstractIn extracorporeal life support (ECLS), there are two main types of oxygenators in clinical use for neonates: polymethylpentene (PMP) hollow fiber and polypropylene (PP) hollow fiber. A retrospective study was performed on neonates (n = 44) who had undergone ECLS for noncardiac indications from 2009 to 2015. Between the two groups (PMP n = 21, PP n = 23), the PP oxygenators failed 91% of the time, whereas the PMP oxygenators failed 43% of the time (p < 0.05). Analysis suggests PMP oxygenators are less prone to failure than PP oxygenators, and they require fewer number of oxygenator changes during a neonatal ECLS.

Extracorporeal membrane oxygenation (ECMO), also known as extracorporeal life support, is the practice of using circulatory assist devices and a gas exchange system to maintain sufficient tissue oxygen delivery, supplementing pulmonary and/or cardiac function in patients whose native physiology is too severely altered to be successfully supported solely by conventional life support techniques (eg, mechanical ventilation and inotropic and vasopressor drugs). ECMO should be considered in patients who are at a high risk of death due to a potentially reversible etiology of cardiopulmonary collapse. Indications for ECMO can be broadly divided into profound respiratory failure and/or cardiogenic shock. The indications include acute respiratory distress syndrome, heart failure, postoperative cardiogenic shock, and as an adjunct to cardiopulmonary resuscitation in patients with cardiac arrest. ECMO is currently experiencing a renaissance, and familiarity with its concepts is important for all critical care practitioners.

No study describes the use of extracorporeal membrane oxygenation (ECMO) in pediatric patients with abdominal sepsis (AS) requiring surgery. A description of outcomes in this patient population would assist clinical decision-making and provide a context for discussions with patients and families. The Extracorporeal Life Support Organization database was queried for pediatric patients (30 days to 18 years) with AS requiring surgery. Forty-five of 61 patients survived (73.8%). Reported bleeding complications (57.1 vs 48.8%), the number of pre-ECMO ventilator hours (208.1 vs 178.9), and the timing of surgery before (50 vs 66.7%) and on-ECMO (50 vs 26.7%) were similar in survivors and nonsurvivors. Decreased pre-ECMO mean pH (7.1 vs 7.3) was associated with increased mortality (odds ratio, 1.49; 95% confidence interval, 1.04 to 2.14). ECMO use for pediatric patients with AS requiring surgery is associated with increased mortality and an increased rate of bleeding complications compared with all pediatric patients receiving ECMO support. Acidemia predicts mortality and provides a potential target of examination for future studies.
