Abstract
Since its first success in 1975, extracorporeal membrane oxygenation (ECMO) has been used with increasing frequency for pulmonary and cardiopulmonary bypass. Use in adults has increased exponentially since the early 2000s, but despite thousands of international cannulations using both veno-arterial (VA) and veno-venous (VV) ECMO, there are still significant hemocompatibility-related adverse events. Current management of anticoagulation has been based on the Extracorporeal Life Support Organization guidance published in 2014 with recent updates published in 2022. Despite this guidance, there is still limited international consensus on how to manage anticoagulation in ECMO. For this review, we completed a comprehensive search of multiple electronic databases to identify studies pertaining to anticoagulation of adult patients on VV or VA-ECMO. The highest priority was given to sources that were prospective, randomized, controlled studies, but in the absence of such resources, observational studies, retrospective uncontrolled studies, and case series/reports were considered for inclusion. This document serves to provide a comprehensive review of the current understanding of management pertaining to anticoagulation relating to ECMO.

Abstract
INTRODUCTION ExtraCorporeal Membrane Oxygenation (ECMO) in pediatric patients with COVID-19 has a survival rate similar to adults. Occasionally, patients may need to be cannulated by an ECMO team in a referring hospital and transported to an ECMO center. The ECMO transport of a COVID-19 patient has additional risks than normal pediatric ECMO transport for the possible COVID-19 transmissibility to the ECMO team and the reduction of the ECMO team performance due to the need of wearing full personal protective equipment. Since pediatric data on ECMO transport of COVID-19 patients are lacking, we explored the outcomes of the pediatric COVID-19 ECMO transports collected in the EuroECMO COVID_Neo/Ped Survey. METHODS We reported five European consecutive ECMO transports of COVID-19 pediatric patients collected in the EuroECMO COVID_Neo/Ped Survey including 52 European neonatal and/or pediatric ECMO centers and endorsed by the EuroELSO from March 2020 till September 2021. RESULTS The ECMO transports were performed for two indications, pediatric ARDS and myocarditis associated to the multisystem inflammatory syndrome related to COVID-19. Cannulation strategies differed among patients according to the age of the patients, transport distance varied between 8 and 390 km with a total transport duration between 5 to 15 h. In all five cases, the ECMO transports were successfully performed without major adverse events. One patient reported a harlequin syndrome and another patient a cannula displacement both without major clinical consequences. Hospital survival was 60% with one patient reporting neurological sequelae. No ECMO team member developed COVID-19 symptoms after the transport. CONCLUSION Five transports of pediatric patients with COVID-19 supported with ECMO were reported in the EuroECMO COVID_Neo/Ped Survey. All transports were performed by an experienced multidisciplinary ECMO team and were feasible and safe for both the patient and the ECMO team. Further experiences are needed to better characterize these transports and draw insightful conclusions.

Defining and understanding the "extra-corporeal membrane oxygenation gap" in the veno-venous configuration: Timing and causes of death. Artif Organs 2021; 46:349-361. [PMID: 34494291 PMCID: PMC9293076 DOI: 10.1111/aor.14058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 07/27/2021] [Accepted: 08/23/2021] [Indexed: 11/17/2022]
Abstract
In‐hospital mortality of adult veno‐venous extracorporeal membrane oxygenation (V‐V ECMO) patients remains invariably high. However, little is known regarding timing and causes of in‐hospital death, either on‐ECMO or after weaning. The current review aims to investigate the timing and causes of death of adult patients during hospital admittance for V‐V ECMO, and to define the V‐V ECMO gap, which is represented by the patients that are successfully weaned of ECMO but still die during hospital stay. A systematic search was performed using electronic MEDLINE and EMBASE databases through PubMed. Studies reporting on adult V‐V ECMO patients from January 2006 to December 2020 were screened. Studies that did not report on at least on‐ECMO mortality and discharge rate were excluded from analysis as they could not provide the required information regarding the proposed V‐V ECMO‐gap. Mortality rates on‐ECMO and after weaning, as well as weaning and discharge rates, were analyzed as primary outcomes. Secondary outcomes were the causes of death and complications. Initially, 35 studies were finally included in this review. Merely 24 of these studies (comprising 975 patients) reported on prespecified V‐V ECMO outcomes (on‐ECMO mortality and discharge rate). Mortality on V‐V ECMO support was 27.8% (95% confidence interval (CI) 22.5%‐33.2%), whereas mortality after successful weaning was 12.7% (95% CI 8.8%‐16.6%, defining the V‐V ECMO gap). 72.2% of patients (95% CI 66.8%‐77.5%) were weaned successfully from support and 56.8% (95% CI 49.9%‐63.8%) of patients were discharged from hospital. The most common causes of death on ECMO were multiple organ failure, bleeding, and sepsis. Most common causes of death after weaning were multiorgan failure and sepsis. Although the majority of patients are weaned successfully from V‐V ECMO support, a significant proportion of subjects still die during hospital stay, defining the V‐V ECMO gap. Overall, timing and causes of death are poorly reported in current literature. Future studies on V‐V ECMO should describe morbidity and mortality outcomes in more detail in relation to the timing of the events, to improve patient management, due to enhanced understanding of the clinical course.

Transition from Simple V-V to V-A and Hybrid ECMO Configurations in COVID-19 ARDS. MEMBRANES 2021; 11:membranes11060434.

Abstract
In SARS-CoV-2 patients with severe acute respiratory distress syndrome (ARDS), Veno-Venous Extracorporeal Membrane Oxygenation (V-V ECMO) was shown to provide valuable treatment with reasonable survival in large multi-centre investigations. However, in some patients, conversion to modified ECMO support forms may be needed. In this single-centre retrospective registry, all consecutive patients receiving V-V ECMO between 1 March 2020 to 1 May 2021 were included and analysed. The patient cohort was divided into two groups: those who remained on V-V ECMO and those who required conversion to other modalities. Seventy-eight patients were included, with fourteen cases (18%) requiring conversions to veno-arterial (V-A) or hybrid ECMO. The reasons for the ECMO mode configuration change were inadequate drainage (35.7%), inadequate perfusion (14.3%), myocardial infarction (7.1%), hypovolemic shock (14.3%), cardiogenic shock (14.3%) and septic shock (7.1%). In multivariable analysis, the use of dobutamine (p = 0.007) and a shorter ICU duration (p = 0.047) predicted the conversion. The 30-day mortality was higher in converted patients (log-rank p = 0.029). Overall, only 19 patients (24.4%) survived to discharge or lung transplantation. Adverse events were more common after conversion and included renal, cardiovascular and ECMO-circuit complications. Conversion itself was not associated with mortality in the multivariable analysis. In conclusion, as many as 18% of patients undergoing V-V ECMO for COVID-19 ARDS may require conversion to advanced ECMO support.

Artif Organs 2021; 45:E236-E246. [PMID: 33507563 DOI: 10.1111/aor.13922] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Revised: 01/08/2021] [Accepted: 01/20/2021] [Indexed: 12/27/2022]
Abstract
Although the number of cancer patients admitted to the intensive care unit is increasing, the data on the use of extracorporeal membrane oxygenation in patients with malignancy are limited. We applied extracorporeal membrane oxygenation to carefully selected patients with active hematologic malignancy or nonhematologic malignancy who experienced respiratory or cardiac failure despite maximal conventional therapy. Patients with active malignancy who underwent extracorporeal membrane oxygenation in our institution between January 2012 and December 2016 were included in this study. The primary outcome of this study was defined as survival to hospital discharge. We also investigated the factors associated with survival to hospital discharge. There were 30 (30.6%) and 68 (69.4%) patients in the hematologic malignancy group and the nonhematologic malignancy group, respectively. Patients in the hematologic malignancy group were younger, more neutropenic, more hypotensive, had a lower Charlson Comorbidity Index, higher sequential organ failure assessment score, and lower platelet count than those in the nonhematologic malignancy group. Forty-six (46.9%) patients were successfully weaned off extracorporeal membrane oxygenation, and 30 (30.6%) patients survived until hospital discharge. Hospital survival rate and survival status 6 months after hospital discharge were significantly lower in patients with hematologic malignancy than in those with nonhematologic malignancy (13.3% vs. 38.2%, P = .026 and 3.3% vs. 26.5%, P = .017, respectively). Multivariate analysis identified an active hematologic malignancy, older age, acidosis, thrombocytopenia, high vasoactive-inotrope score, and respiratory failure as the risk factors for in-hospital death. Patients with hematologic malignancy requiring extracorporeal membrane oxygenation support had significantly lower rates of hospital survival and 6-month survival after discharge than patients with nonhematologic malignancy. Therefore, extracorporeal membrane oxygenation for treating cardiac or respiratory failure should only be considered in highly selected patients with hematologic malignancy.

Extracorporeal Life Support in Adult Patients: A Global Perspective of the Last Decade. Dimens Crit Care Nurs 2019; 38:123-130.

Abstract
Extracorporeal life support (ECLS) is an external medical device to treat critically ill patients with cardiovascular and respiratory failure. In a nutshell, ECLS is only a "bridging" mechanism that provides life support while the heart and/or the lungs is recovering either by therapeutic medical interventions, transplantation, or spontaneously. Extracorporeal life support has been developed since 1950s, and many studies were conducted to improve ECLS techniques, but unfortunately, the survival rate was not improved. Because of Dr Bartlett's success in using ECLS to treat neonates with severe respiratory distress in 1975, ECLS is made as a standard lifesaving therapy for neonates with severe respiratory distress. However, its use for adult patients remains debatable. The objectives of this study are to outline and provide a general overview of the use of ECLS especially for adult patients for the past 10 years and to elaborate on the challenges encountered by each stakeholder involved in ECLS. The data used for this study were extracted from the ELSO Registry Report of January 2018. Results of this study revealed that the number of ECLS centers and the use of ECLS are increasing over the year for the past decade. There was also a shift of the patient's age category from neonatal to adult patients. However, the survival rates for adult patients are relatively low especially for cardiac and extracorporeal cardiopulmonary resuscitation cases. To date, the complications are still the major challenge of ECLS. Other challenges encountered by the stakeholders in ECLS are the limited amount of well-trained and experienced ECLS teams and centers, the limited government expenditure on health, and the lack of improvement and development of ECLS techniques and devices. Further studies are needed to evaluate the value of ECLS for adult patients.

Abstract
BACKGROUND Extracorporeal membrane oxygenation is a resource-intensive mode of life-support potentially applicable when conventional therapies fail. Given the initial success of extracorporeal membrane oxygenation to support neonates and infants in the 1980s, indications have expanded to include adolescents, adults, and selected moribund patients during cardiopulmonary resuscitation. This single-institution analysis was conducted to evaluate programmatic growth, outcomes, and risk for death despite extracorporeal membrane oxygenation across all ages and diseases. METHODS Beginning in 1989, we registered prospectively all extracorporeal membrane oxygenation patient data with the Extracorporeal Life Support Organization. We queried this registry for our institution-specific data to compare the parameter of "discharge alive" between age groups (neonatal, pediatric, adult), disease groups (respiratory, cardiac, cardiopulmonary resuscitation), and modes of extracorporeal membrane oxygenation (veno-venous; veno-arterial). Extracorporeal membrane oxygenation-specific complications (mechanical, hemorrhagic, neurologic, renal, cardiovascular, pulmonary, infectious, metabolic) were analyzed similarly. Descriptive statistics, Kaplan-Meier, and linear regression analyses were conducted. RESULTS After 1,052 extracorporeal membrane oxygenation runs, indications have expanded to include adults, to supplement cardiopulmonary resuscitation, to support hemodialysis in neonates and plasmapheresis in children, and to bridge all age patients to heart and lung transplant. Overall survival to discharge was 52% and was better for respiratory diseases (P < .001). Probability of individual survival decreased to <50% if pre-extracorporeal membrane oxygenation mechanical ventilation exceeded respectively 123 hours for cardiac, 166 hours for cardiopulmonary resuscitation, and 183 hours for respiratory diseases (P = .013). Complications occurred most commonly among cardiac and cardiopulmonary resuscitation runs (P < .001), the veno-arterial mode (P < .001), and in adults (P = .044). CONCLUSION Our extracorporeal membrane oxygenation program, an Extracorporeal Life Support Organization-designated Center of Excellence, has experienced substantial growth in volume and indications, including increasing age and disease severity. Considering the entire cohort, pre-extracorporeal membrane oxygenation ventilation exceeding 7 days was associated with an increased probability of death.

Abstract
Extracorporeal membrane oxygenation (ECMO) is a cumbersome procedure. Alternatively, mechanical lung assist can be realized with an intravascular gas exchanger (IVOX). To assess the degree of initial anticoagulation required during intravascular lung assist, we evaluated two regimens of systemic heparinization in 10 bovine experiments. The animals were randomly assigned to two groups with either full systemic heparinization (heparin loading dose 300 IU/kg bodyweight; activated coagulation time (ACT) > 480 s) or low systemic heparinization (heparin loading dose 100 IU/kg bodyweight; ACT > 180 s). The surface heparinized intravascular gas exchanger was placed in the caval axis under fluoroscopic control, and a standard battery of blood samples was drawn before and at regular intervals during the procedure. After six hours of intravascular lung assist the device was explanted, drained, weighed, and carefully analysed. Preassist haematocrit was 25 ± 5% for full versus 24 ± 7% for low (NS) as compared with 23 ± 8% for full versus 26 ± 3% for low (NS) postassist. Platelet levels were 100 ± 25 for full versus 100 ± 21 % for low (NS) preassist as compared with 64 ± 22% for full versus 78 ± 22% for low (NS) postassist. Mean ACT was 157 ± 12 s for full versus 158 ± 18 for low (NS) preassist as compared with 800 ± 244 s versus 219 ± 25 for low (p < 0.05) postassist. Thrombin time was 20 ± 2 s for full versus 23 ± 2 s for low (NS) as compared with > 200 s for both groups after assist. Relative fibrinopeptide A levels were 7.3 ± 1.1 ng/ml for full versus 6.3 ± 1.6 ng/ml for low (NS) preassist as compared with 4.7 ± 4.1 ng/ml for full versus 5.8 ± 0.9 ng/ml for low (NS) postassist. CO2 transfer was 40 ± 10 ml/min for full versus 36 ± 10 ml/min for low (NS) at the begining as compared with 45 ± 25 ml/min for full versus 46 ± 15 for low (NS) at the end. Weight increase due to device deposits (clots) was 14 ± 11 g for full versus 13 ± 10 g for low systemic heparinization (NS). Intravascular lung assist with low versus full systemic heparinization appeared to result in similar activation of the coagulation system, device deposits and gas transfer rates. Considering our clinical experience we can say that application of the device with reduced systemic heparinization is useful in selected patients.

Abstract
The need for postcardiotomy mechanical support is uncommon and likely to decline. A mixture of options is necessary to meet the diverse indications for cardiac support in a comprehensive heart failure program. Between January 1997 and December 2000, 29 adult, neonate, and infant cardiac surgical patients were supported on an extracorporeal life support system. Indications for cardiac assist included post-cardiotomy low cardiac output syndrome, and hyperacute rejection after cardiac transplantation. Data for analysis were collected prospectively. Survival on the life support system was 20/29 (69%) and 12 patients (41%) survived to discharge. The mean time to starting extracorporeal life support was longer in survivors than non-survivors. The extracorporeal life support system provides effective cardiopulmonary and end-organ support.

Abstract
A 38-year-old male was admitted with symptoms of upper respiratory infection. Despite medical treatment, his symptoms of dyspnea and anxiety became aggravated, and bilateral lung infiltration was noted on radiological imaging studies. His hypoxemia failed to improve even after the application of endotracheal intubation with mechanical ventilator care, and we therefore decided to initiate venovenous extracorporeal membrane oxygenation (VV ECMO) for additional pulmonary support. On his twentieth day of hospitalization, hypotension and desaturation (arterial saturated oxygen <85%) developed, and right ventricular failure was confirmed by two-dimensional echocardiography. Therefore, we changed from VV ECMO to venoarteriovenous (VAV) ECMO, and the patient ultimately recovered. In this case, right ventricular dysfunction and volume overloading were induced by long-term VV ECMO therapy, and we successfully treated these conditions by changing to VAV ECMO.

Abstract
Extracorporeal membrane oxygenation has evolved in design, technology, patient selection, insertion techniques, adjunct devices, and management in the past 45 years since it began. Outcomes have improved and indications have expanded. It continues to be an expeditious, cost-effective tool for rapid resuscitation of patients with cardiorespiratory failure, whose outcomes without extracorporeal membrane oxygenation intervention are predominately fatal. However, results are still moderately satisfactory, and the ethical aspects of ongoing care need to be at the forefront of daily family discussions in patients for whom a bridge to transplant or definitive device is not possible.

Abstract
BACKGROUND Acute respiratory failure is a serious issue that occasionally occurs after weaning from cardiopulmonary bypass (CPB) after heart surgery. This condition can be refractory to mechanical ventilation and the mortality rate is high. Venovenous extracorporeal membrane oxygenation (VV-ECMO) is applied to treat acute lung failure after CPB at our institution. This report describes the use of VV-ECMO after cardiac surgery at a single institution. METHODS We analyzed the outcomes of 11 patients who developed severe acute respiratory failure requiring VV-ECMO after undergoing heart surgery with a cardiopulmonary bypass. RESULTS Four (36.4%) patients died in hospital. One patient required conversion from VV- to venoarterial (VA-) ECMO because of circulatory instability. One patient each died of respiratory failure and heart failure and two died of ischemic colitis. Lung damage secondarily developed in these four patients to other disabled organs. Seven (63.6%) patients whose lungs were primarily disabled were weaned from VV-ECMO upon recovery from respiratory failure and were ambulatory at the time of discharge from hospital. The ratio of PaO2/FIO2 (P/F) at 24 h after starting VV-ECMO did not significantly differ between survivors and non-survivors (187.9 ± 57.7 vs. 135.5 ± 20.5, p = 0.10), but tended to be higher in survivors. Non-survivors were significantly older than survivors. CONCLUSION Patients who develop severe acute respiratory failure after undergoing heart surgery using cardiopulmonary bypass derive a survival benefit from VV-ECMO.

Abstract
From early May 2009, the novel influenza A (H1N1) pandemic affected mainland China. Of those infected, a small proportion of patients developed acute respiratory distress syndrome (ARDS) so rapidly and severely that conventional ventilation treatment was ineffective. As an alternative treatment, the effect of extracorporeal membrane oxygenation (ECMO) was evaluated. From November 2009 to January 2010, all patients suffering from influenza A (H1N1)-associated ARDS referred to Beijing Anzhen Hospital for treatment with ECMO were enrolled. We describe the characteristics, treatment, and outcomes of these patients at 1- and 3-month follow-up. Nine patients (four females; mean age, 31.2 [21-59] years) from four centers were enrolled. All females had a history of recent pregnancy or had recently given birth. Before ECMO, patients had severe respiratory failure despite advanced mechanical ventilatory support with a mean partial pressure of arterial oxygen/fraction of inspired oxygen of 52.9 ± 5.1 (45.0-63.8) mm Hg, positive end-expiratory pressure of 17.2 ± 4.2 cmH(2) O, and a Murray Lung Score of 3.6 (3.25-3.75). All nine patients were treated with veno-venous ECMO via percutaneous access. The mean duration of ECMO support was 436.6 ± 652.1 h (67.0-2160.0). At the end of 1-year follow-up, five patients (55.7%) were weaned from ECMO. Five patients (55.7%) survived to hospital discharge. Four patients (44.4%) died while undergoing ECMO. The mean length of intensive care unit and hospital stay was 4-204 days (median, 32) and 4-234 days (median, 38), respectively. There was no significant difference between survivors and nonsurvivors in the screened parameters. Use of ECMO for critically ill patients with 2009 influenza A (H1N1)-related ARDS is feasible and effective. However, this treatment is technically demanding. For success, careful selection of patients is crucial.

Abstract
BACKGROUND Acute lung failure (ALF) is an increasing problem that can be treated with venovenous extracorporeal membrane oxygenation (vv-ECMO). This report summarizes prospectively collected data of an institutional experience with vv-ECMO. METHODS From January 2007 to December 2010, 176 patients (mean age, 48 ± 16; range, 14-78 years) with ALF refractory to conventional therapy were supported with vv-ECMO. The general indication for vv-ECMO was a partial oxygen pressure/fraction of inspired oxygen (Fio(2)) < 80 mm Hg under a Fio(2) of 1.0, a positive end-expiratory pressure of 18 cm H(2)O, and refractory respiratory acidosis (pH < 7.25), despite optimization of conservative therapy. RESULTS All patients underwent peripheral cannulation. In 59 cases, vv-ECMO was placed in another facility with ECMO transport by helicopter or ambulance. The mean vv-ECMO support interval was 12 ± 9.0 days (range, 1-67 days). During ECMO, 12 patients (7%) could be extubated and stepwise mobilized. Cannula-related complications during long-term support occurred in 14%, which was mostly minor bleeding. Overall survival was 56%: 58 patients (33%) died during mechanical support, and 20 (11%) died after weaning from the system. The best outcome was noted in trauma patients. Risk factors were mainly advanced age and multiorgan failure. CONCLUSION Modern vv-ECMO is an excellent treatment in patients with severe ALF and should be more liberally used.

Abstract
OBJECTIVE To evaluate clinical and treatment factors for patients recorded in the Extracorporeal Life Support Organization (ELSO) registry and survival of adult extracorporeal membrane oxygenation (ECMO) respiratory failure patients. DESIGN AND PATIENTS Retrospective case review of the ELSO registry from 1986-2006. Data were analyzed separately for the entire time period and the most recent years (2002-2006). RESULTS Of 1,473 patients, 50% survived to discharge. Median age was 34 years. Most patients (78%) were supported with venovenous ECMO. In a multi-variate logistic regression model, pre-ECMO factors including increasing age, decreased weight, days on mechanical ventilation before ECMO, arterial blood pH <or= 7.18, and Hispanic and Asian race compared to white race were associated with increased odds of death. For the most recent years (n = 600), age and PaCO(2) >or= 70 compared to PaCO(2) <or= 44 were also associated with increased odds of death. The two diagnostic categories acute respiratory failure and asthma compared to ARDS were associated with decreased odds of mortality as was venovenous compared to venoarterial mode. CPR and complications while on ECMO including circuit rupture, central nervous system infarction or hemorrhage, gastrointestinal or pulmonary hemorrhage, and arterial blood pH < 7.2 or >7.6 were associated with increased odds of death. CONCLUSIONS Survival among this cohort of adults with severe respiratory failure supported with ECMO was 50%. Advanced patient age, increased pre-ECMO ventilation duration, diagnosis category and complications while on ECMO were associated with mortality. Prospective studies are needed to evaluate the role of this complex support mode.

Abstract
PURPOSE OF REVIEW The past 35 years have provided a wealth of evidence that mechanical ventilation, although potentially life saving, can injure the lungs. Recent evidence suggests that limiting ventilating gas volumes can reduce patient mortality, but may result in progressive parenchymal derecruitment and alveolar hypoventilation, potentially aggravating systemic hypercarbia and hypoxemia. This review summarizes the current recommendations on a controversial, invasive technique termed 'extracorporeal life support' as a means to provide temporary pulmonary support during 'lung-protective' strategies. RECENT FINDINGS Extracorporeal life support has been implemented since the origins of cardiopulmonary bypass in the 1950s, but differs in several important ways from cardiopulmonary bypass, including its prolonged duration of application. Because extracorporeal life support serves only to supplement physiological derangements and is not therapeutic, patient selection critically impacts results. Whereas reversible neonatal processes such as meconium aspiration and persistent fetal circulation have fostered clinical trials demonstrating the efficacy of extracorporeal life support, adult cardiopulmonary failure extracorporeal life support trials have proved less compelling. Despite two prospective randomized trials that failed to demonstrate its efficacy, adult extracorporeal life support continues in limited centers of excellence. Adult extracorporeal life support survival rates for respiratory failure average 50% when strict criteria are met, but it remains unclear whether these results represent improved outcomes. SUMMARY Extracorporeal life support is an invasive technique that can provide support to the failing lung. Clinical trials have demonstrated its efficacy in neonatal and pediatric patients, but data in adults are less clear. An ongoing trial in the UK will soon address this important issue.

Abstract
BACKGROUND Primary graft dysfunction (PGD) after lung transplantation (LTx) carries a significant mortality and clinical management is controversial. Extracorporeal membrane oxygenation (ECMO) has been used infrequently for recovery from acute lung injury (ALI) in this setting. We reviewed our experience with ECMO after primary LTx. METHODS The present study is a retrospective analysis of all LTx patients between 1991 and 2004. Twenty-two patients sustained severe PGD with subsequent placement on ECMO. We analyzed indications and 30-day, 1-year and 3-year mortality. Complications and incidence of multiple-organ failure (MOF) were determined. Critical appraisal of the evidence available to date was performed. RESULTS A total of 297 LTxs were performed during the study period, with 97.5%, 88.6% and 73.8% survival at 30 days, 1 year and 3 years, respectively. Twenty-two patients (7.9%) had severe allograft dysfunction leading to ECMO support. Twelve patients received single-lung (SLTx), 8 double-lung (BLTx), 1 single-lung/kidney (SLKTx) and 1 heart/lung (HLTx) transplantation. Thirty-day, 1-year and 3-year survival of LTx recipients with ECMO support post-operatively were 74.6%, 54% and 36%, respectively. MOF was the predominant cause of death (58.3%) in patients on ECMO support for PGD. CONCLUSIONS Our data suggest that, in addition to prolonged ventilation and pharmacologic support, ECMO should be considered as a bridge to recovery from PGD in lung transplantation. Early institution of ECMO may lead to diminished mortality in the setting of ALI despite the high incidence of MOF. Late institution of ECMO was associated with 100% mortality in this investigation.

Between May 1990 and January 1999, 100 patients (68 adult, 32 pediatric) with severe respiratory or cardiac instability were successfully transported to the University of Michigan Medical Center on extracorporeal life support. Diagnoses included adult respiratory distress syndrome (n = 78), cardiac failure (n = 7), sepsis (n = 7), asthma (n = 5), respiratory distress syndrome (of newborn) (n = 2), and airway compromise (n = 1). Of the patients, 53 were supported with venovenous bypass and 47 with venoarterial bypass. Patients were transported by ground ambulance (n = 80), helicopter (n = 15), or fixed-wing aircraft (n = 5). The median transport distance was 44 miles (range 2-790 miles), and the median transport time was 5 hours and 30 minutes (range: 1 h 33 min to 16 h 6 min). Sixty-six patients (66%) survived to discharge. One death occurred during cannulation, and two patients died before cannulation began. Complications that occurred during transport included 10 cases of electrical failure, 3 cases of circuit tubing leakage, and 1 case each of circuit rupture, membrane lung thrombosis, and membrane lung leakage. None of the complications occurring during transport had an adverse effect on outcome. We conclude that the long distance transport of patients on extracorporeal life support can be safely accomplished and is an effective option for the unstable patient with severe respiratory or cardiac failure.

Abstract
OBJECTIVE To evaluate hemodynamic stability and gas exchange in a neonatal animal model of pumpless arteriovenous extracorporeal membrane oxygenation (AV-ECMO) with extracorporeal shunt flow of up to 15% of cardiac output during variable ventilation and oxygenation. DESIGN Prospective study. SETTING Research laboratory in a hospital. SUBJECTS Seven lambs (5.5 +/- 0.6 kg, mean +/- sd). INTERVENTIONS The lambs initially were anesthetized by 50 mg/kg ketamine intravenously. After tracheostomy, the lambs were mechanically ventilated and paralyzed by using 1 mg/kg vecuronium bromide followed by 0.1 mg.kg(-1).hr(-1). One femoral vein was cannulated with a pulmonary artery flotation catheter and used for cardiac output and pulmonary artery pressure measurements. A femoral artery was cannulated for measuring mean arterial blood pressure, measuring heart rate, and blood sampling for gas exchange analyses. Finally, the right internal jugular vein and carotid artery were cannulated and used for the AV-ECMO. Normothermia (38 +/- 0.5 degrees C), fluid balance (5 mL.kg(-1).hr(-1) normal saline), and anesthesia (5 mg.kg(-1).hr(-1), intravenous ketamine) were maintained. Ventilator settings were adjusted to establish a baseline Paco2 (25-35 mm Hg) at an Fio2 of 0.4. The AV-ECMO circuit was established by using a hollow fiber oxygenator, primed with maternal sheep blood (150-200 mL). MEASUREMENTS AND MAIN RESULTS The physiologic effects of the AV-ECMO shunt were evaluated at 15, 25, and 40 mL.kg(-1).hr(-1) ECMO flow, corresponding roughly to 4%, 8%, and 15% of the cardiac output values. The baseline minute volume was maintained during stepwise increases in arteriovenous shunt. A significant increase in endogenous cardiac output occurred at arteriovenous shunt of 25 and 40 mL.kg(-1).hr(-1) (analysis of variance followed by Tukey-Kramer multiple comparisons test), which was attributed to a significant increase of 30% in the heart rate. Effective cardiac output (difference between the thermodilution value and the AV-ECMO flow rate) and mean arterial blood pressure were not significantly changed. CO2 removal, measured at 15% arteriovenous shunt, was significantly increased with decreasing ventilation to 25% and 50% of the baseline (analysis of variance and Tukey-Kramer test). Oxygenation through the membrane was measured after reducing inspired Fio2 from 0.4 to 0.21, 0.15, and 0.10 with 15% arteriovenous shunt and baseline minute ventilation. Oxygen delivery by the oxygenator was significantly increased at Fio2 of 0.10, providing a maximum of 19.5% of the total oxygen consumption at an arterial hemoglobin-oxygen saturation of 60%. CONCLUSIONS Healthy lambs are capable of maintaining effective cardiac output in the presence of moderate arteriovenous shunts (15%). AV-ECMO may provide efficient ventilatory support in the neonatal population with hypercapnia. The amount of oxygen delivery with AV-ECMO depends on arterial desaturation.

Abstract
OBJECTIVE To systematically review clinical trials in acute respiratory distress syndrome (ARDS). DATA SOURCES Computerized bibliographic search of published research and citation review of relevant articles. STUDY SELECTION All clinical trials of therapies for ARDS were reviewed. Therapies that have been compared in prospective, randomized trials were the focus of this analysis. DATA EXTRACTION Data on population, interventions, and outcomes were obtained by review. Studies were graded for quality of scientific evidence. MAIN RESULTS Lung protective ventilator strategy is supported by improved outcome in a single large, prospective trial and a second smaller trial. Other therapies for ARDS, including noninvasive positive pressure ventilation, inverse ratio ventilation, fluid restriction, inhaled nitric oxide, almitrine, prostacyclin, liquid ventilation, surfactant, and immune-modulating therapies, cannot be recommended at this time. Results of small trials using corticosteroids in late ARDS support the need for confirmatory large clinical trials. CONCLUSIONS Lung protective ventilator strategy is the first therapy found to improve outcome in ARDS. Trials of prone ventilation and fluid restriction in ARDS and corticosteroids in late ARDS support the need for large, prospective, randomized trials.

Abstract
Severe pulmonary reimplantation response after lung transplantation is not very common, although the mortality can be high. We present a patient who developed an extremely severe reperfusion injury after bilateral lung transplantation. Because of severe hypoxia and hemodynamic instability, despite aggressive ventilator settings, venoarterial extracorporeal membrane oxygenation (ECMO) was instituted using the femoral approach at the bedside. During ECMO, the patient developed a thoracic wall hematoma that was treated with transfusion alone. After 50 h of ECMO, his chest radiograph had dramatically improved, his oxygen need had been reduced to 50%, and he was successfully weaned from ECMO. Two years later, he is doing extremely well. Therefore, institution of ECMO using the femoral approach can be performed safely at the bedside in the ICU, and can be lifesaving in the context of a very severe reimplantation response after lung transplantation.

Abstract
BACKGROUND/PURPOSE The objective of this study was to show the safety and efficacy of a method of percutaneous cannulation for venovenous extracorporeal life support (ECLS) access in nonneonatal (>10 kg) pediatric patients. METHODS Between June 1992 and October 1998, 26 pediatric patients (age range, 3 to 17 years; weight range, 19 to 100 kg) underwent attempted percutaneous cannulation for venovenous ECLS at our institution. Venous drainage access was attempted using a modified Seldinger technique via the right internal jugular vein (RIJ, n = 22) or right femoral vein (RFV, n = 4). Reinfusion access was attempted via the RFV (n = 19), RIJ (n = 4), or left femoral vein (n = 3). RESULTS The percutaneous technique was successful in 24 of 26 patients (92.3%). Maximum blood flow during ECLS was 80.1 +/- 30.0 mL/kg/min, generating a postmembrane lung outlet pressure of 138 +/- 54.8 mm Hg. Adequate gas exchange was achieved in all patients, and survival to discharge was 79.2%. There was no procedure-related mortality. Complications potentially related to the percutaneous technique included RIJ thrombosis (n = 1) detected after decannulation and cannula site bleeding (n = 3). CONCLUSION Percutaneous access may be used safely and effectively for venovenous ECLS in pediatric patients.

Abstract
OBJECTIVE To present a series of 30 adult trauma patients who received extracorporeal life support (ECLS) for pulmonary failure and to retrospectively review variables related to their outcome. METHODS In a Level I trauma center between 1989 and 1997, ECLS with continuous heparin anticoagulation was instituted in 30 injured patients older than 15 years. Indication was for an estimated mortality risk greater than 80%, defined by a PaO2: FIO2 ratio less than 100 on 100% FIO2, despite pressure-mode inverse ratio ventilation, optimal positive end-expiratory pressure, reasonable diuresis, transfusion, and prone positioning. Retrospective analysis included demographic information (age, gender, Injury Severity Score, injury mechanism), pulmonary physiologic and gas-exchange values (pre-ECLS ventilator days [VENT days], PaO2:FIO2 ratio, mixed venous oxygen saturation [SvO2], and blood gas), pre-ECLS cardiopulmonary resuscitation, complications of ECLS (bleeding, circuit problems, leukopenia, infection, pneumothorax, acute renal failure, and pressors on ECLS), and survival. RESULTS The subjects were 26.3+/-2.1 years old (range, 15-59 years), 50% male, and had blunt injury in 83.3%. Pulmonary recovery sufficient to wean the patient from ECLS occurred in 17 patients (56.7%), and 50% survived to discharge. Fewer VENT days and more normal SvO2 were associated with survival. The presence of acute renal failure and the need for venoarterial support (venoarterial bypass) were more common in the patients who died. Bleeding complications (requiring intervention or additional transfusion) occurred in 58.6% of patients and were not associated with mortality. Early use of ECLS (VENT days < or = 5) was associated with an odds ratio of 7.2 for survival. Fewer VENT days was independently associated with survival in a logistic regression model (p = 0.029). Age, Injury Severity Score, and PaO2:FIO2 ratio were not related to outcome. CONCLUSION ECLS has been safely used in adult trauma patients with multiple injuries and severe pulmonary failure. In our series, early implementation of ECLS was associated with improved survival. Although this may represent selection bias for less intractable forms of acute respiratory distress syndrome, it is our experience that early institution of ECLS may lead to improved oxygen delivery, diminished ventilator-induced lung injury, and improved survival.

Abstract
OBJECTIVE Intracranial hemorrhage is a recognized complication in neonates and infants on extracorporeal membrane oxygenator support and various risk factors associated with this have been defined. The prevalence and risk factors associated with intracranial hemorrhage in adults on extracorporeal membrane oxygenator support are unknown and this study was performed to define these factors. METHODS A retrospective study of adults supported with extracorporeal membrane oxygenators at a single institution between January 1992 and December 1996 was performed. Age, gender, weight, body surface area, renal function, anticoagulation, coagulation variables, blood flow, arterial pressure, arterial cannulation sites, duration of support, extracranial bleeding, native cardiac function and presence of intracranial microemboli were analyzed to determine the risk factors for intracranial hemorrhage. RESULTS Fourteen out of 74 adults on extracorporeal membrane oxygenator support had intracranial hemorrhage (18.9%). An increased risk of intracranial hemorrhage showed a positive correlation with female gender (P = 0.02, odds ratio 6.5), use of heparin (P = 0.05, odds ratio 8.5), creatinine greater than 2.6 mg/ dl (P = 0.009, odds ratio 6.5), need for dialysis (P = 0.03, odds ratio 4.3) and thrombocytopenia (P = 0.007, odds ratio 18.3). Diminishing renal function and the need for dialysis were associated with increasing duration of support. Multivariable logistic regression showed female gender and thrombocytopenia, especially with platelet counts less than 50000 cells/mm3 to be the most important predictors of intracranial hemorrhage. Intracranial hemorrhage was associated with a mortality of 92.3% compared with a mortality of 61% in those without intracranial hemorrhage (P = 0.027). CONCLUSION Intracranial hemorrhage is a significant complication in adults on extracorporeal membrane oxygenator support. Judicious management of anticoagulation, prevention of renal failure and aggressive correction of thrombocytopenia may help to lower the risk of intracranial hemorrhage in adults on extracorporeal membrane oxygenator support.

Abstract
INTRODUCTION In the United States, venovenous extracorporeal life support has traditionally been performed with atrial drainage and femoral reinfusion (atrio-femoral flow). Although flow reversal (femoro-atrial flow) may alter recirculation and extracorporeal flow, no direct comparison of these 2 modes has been undertaken. OBJECTIVE Our goal was to prospectively compare atrio-femoral and femoro-atrial flow in adult venovenous extracorporeal life support for respiratory failure. METHODS A modified bridge enabling conversion between atrio-femoral and femoro-atrial flow was incorporated in the extracorporeal circuit. Bypass was initiated in the direction that provided the highest pulmonary arterial mixed venous oxygen saturation, and the following measurements were taken: (1) maximum extracorporeal flow, (2) highest achievable pulmonary arterial mixed venous oxygen saturation, and (3) flow required to maintain the same pulmonary arterial mixed venous oxygen saturation in both directions. Flow direction was then reversed, and the measurements were repeated. Data were compared with paired t tests and are presented as mean +/- standard deviation. RESULTS Ten patients were studied, and 9 were included in the data analysis. Femoro-atrial bypass provided (1) higher maximal extracorporeal flow (femoro-atrial flow = 55.6 +/- 9.8 mL/kg per minute, atrio-femoral flow = 51.1 +/- 11.1 mL/kg per minute; P = .04) and (2) higher pulmonary arterial mixed venous oxygen saturation (femoroatrial flow = 89.9% +/- 6.6%, atrio-femoral flow = 83.2% +/- 4.2%; P = .006); (3) furthermore, it required less flow to maintain an equivalent pulmonary arterial mixed venous oxygen saturation (femoro-atrial flow = 37.0 +/- 12.2 mL/kg per minute, atrio-femoral flow = 46.4 +/- 8.8 mL/kg per minute; P = .04). CONCLUSIONS During venovenous extracorporeal life support, femoro-atrial bypass provided higher maximal extracorporeal flow, higher pulmonary arterial mixed venous oxygen saturation, and required comparatively less flow to maintain an equivalent mixed venous oxygen saturation than did atrio-femoral bypass.

Abstract
We present an interesting case of the first adult reported in the United States to suffer from thermal burns, adult respiratory distress syndrome (ARDS) and to be treated with extracorporeal membrane oxygenation (ECMO) who survived. Our patient is a 26 year old male who sustained thermal burns (12% TBSA) to his face and anterior trunk and broncoscopically demonstrable inhalation injury. He was transported to our regional burn center for burn wound care and ventilatory support. The patient was treated with silver sulfadiazine 1% to his wounds which healed per primam. Because of low oxygen saturation he required increasing FIO2. The following parameters: FIO2= 1, PEEP = 17, minute ventilation of 15.1 1, peak airway pressure of 45 and mean of 27, along with chest X-rays corroborated the severity of ARDS. The patient failed volume control ventilation. A trial of pressure ventilation was attempted but the patient only reached O2 saturation in the low 80s. At this point, the decision was made to transfer the patient to a hospital capable of ECMO treatment. The patient was subsequently treated with veno venous ECMO. Six weeks later the patient was discharged from the hospital off all ventilatory support.

Abstract
OBJECTIVES The purpose of this article is to evaluate outcome in adult patients with severe respiratory failure managed with an approach using (1) limitation of end inspiratory pressure, (2) inverse ratio ventilation, (3) titration of PEEP by SvO2, (4) intermittent prone positioning, (5) limitation of FiO2, (6) diuresis, (7) transfusion, and (8) extracorporeal life support (ECLS) if patients failed to respond. PATIENTS AND METHODS This study was designed as a retrospective review in the intensive care unit of a tertiary referral hospital. One-hundred forty-one consecutive patients with hypoxic (n = 135) or hypercarbic (n = 6) respiratory failure referred for consideration of ECLS between 1990 and 1996. Overall, initial PaO2/FiO2 (P/F) ratio was 75+/-5 (median = 66). RESULTS Lung recovery occurred in 67% of patients and 62% survived. Forty-one patients improved without ECLS (83% survived); 100 did not and were supported with ECLS (54% survived). Survival was greater in patients cannulated within 12 hours of arrival (59%) compared with those cannulated after 12 hours (40%, P < .05). Multiple logistic regression identified age, duration of mechanical ventilation before transfer, four or more dysfunctional organs, and the requirement for ECLS as independent predictors of mortality. CONCLUSIONS An approach that emphasizes lung protection and early implementation of extracorporeal life support is associated with high rates of survival in patients with severe respiratory failure.

Abstract
OBJECTIVE The authors retrospectively reviewed their experience with extracorporeal life support (ECLS) in 100 adult patients with severe respiratory failure (ARF) to define techniques, characterize its efficacy and utilization, and determine predictors of outcome. SUMMARY BACKGROUND DATA Extracorporeal life support maintains gas exchange during ARF, providing diseased lungs an optimal environment in which to heal. Extracorporeal life support has been successful in the treatment of respiratory failure in infants and children. In 1990, the authors instituted a standardized protocol for treatment of severe ARF in adults, which included ECLS when less invasive methods failed. METHODS From January 1990 to July 1996, the authors used ECLS for 100 adults with severe acute hypoxemic respiratory failure (n = 94): paO2/FiO2 ratio of 55.7+/-15.9, transpulmonary shunt (Qs/Qt) of 52+/-22%, or acute hypercarbic respiratory failure (n = 6): paCO2 84.0+/-31.5 mmHg, despite and after maximal conventional ventilation. The technique included venovenous percutaneous access, lung "rest," transport on ECLS, minimal anticoagulation, hemofiltration, and optimal systemic oxygen delivery. RESULTS Overall hospital survival was 54%. The duration of ECLS was 271.9+/-248.6 hours. Primary diagnoses included pneumonia (49 cases, 53% survived), adult respiratory distress syndrome (45 cases, 51 % survived), and airway support (6 cases, 83% survived). Multivariate logistic regression modeling identified the following pre-ECLS variables significant independent predictors of outcome: 1) pre-ECLS days of mechanical ventilation (p = 0.0003), 2) pre-ECLS paO2/FiO2 ratio (p = 0.002), and 3) age (years) (p = 0.005). Modeling of variables during ECLS showed that no mechanical complications were independent predictors of outcome, and the only patient-related complications associated with outcome were the presence of renal failure (p < 0.0001) and significant surgical site bleeding (p = 0.0005). CONCLUSIONS Extracorporeal life support provides life support for ARF in adults, allowing time for injured lungs to recover. In 100 patients selected for high mortality risk despite and after optimal conventional treatment, 54% survived. Extracorporeal life support is extraordinary but reasonable treatment in severe adult respiratory failure. Predictors of survival exist that may be useful for patient prognostication and design of future prospective studies.

Abstract
Extracorporeal life support is a therapeutic modality that can provide cardiorespiratory support for multiply injured patients. Fourteen patients with multiple trauma who sustained pelvic or long bone fractures were referred for treatment with extracorporeal life support at the University of Michigan Medical Center. All patients were considered morlbund secondary to their pulmonary injury. Six of the 14 patients had bilateral pulmonary contusions. The mean Injury Severity Score was 19. Twelve of the 14 patients had femoral or pelvic fractures or both. Eight patients had orthopaedic injuries initially treated with traction. The most common complication during extracorporeal life support management was bleeding, which occurred in eight of 14 patients. Eight of the 14 patients survived. Seven of eight patients with less than 6 days of mechanical ventilation before initiation of extracorporeal life support survived. Only one of six patients with six or more days of mechanical ventilation before initiation of extracorporeal life support survived. Patients with significant orthopaedic trauma and severe pulmonary compromise have an extremely high mortality risk. Appropriate aggressive fracture management remains the most important intervention to decrease the risk of pulmonary compromise. Early initiation of extracorporeal life support can be an additional lifesaving intervention in select patients with orthopaedic trauma who have respiratory failure refractory to conventional mechanical ventilation.

Abstract
OBJECTIVE To investigate the relationship between the period of mechanical ventilation before extracorporeal life support and survival in patients with respiratory failure. DESIGN Retrospective review. SETTING Surgical intensive care unit at a university medical center. PATIENTS Thirty-six consecutive adult patients with severe respiratory failure managed with extracorporeal life support. INTERVENTIONS Extracorporeal life support was utilized in 36 acute respiratory failure adult patients with a variety of diagnoses and an estimated mortality rate of > 90%. Management protocols were followed before and during extracorporeal life support. The 36 patients were physiologically similar before extracorporeal life support was initiated: shunt of 48 +/- 17%; F10(2) of 1.0 +/- 0.1; peak inspiratory pressure of 56 +/- 16 cm H2O; positive end-expiratory pressure of 14 +/- 6 cm H2O; and respiratory rate of 23 +/- 10 breaths/ min. Ventilation was utilized for 1 to 17 days before extracorporeal life support. Typical lung rest settings during extracorporeal life support were F10(2) of 0.40, peak inspiratory pressure of 30 cm H2O, positive end-expiratory pressure of 10 cm H2O, and respiratory rate of 6 breaths/min. Death was almost always secondary to end-stage pulmonary failure. MEASUREMENTS AND MAIN RESULTS Survival (hospital discharge) in these 36 patients was inversely associated with the number of days of preextracorporeal life support ventilation, with a 50% mortality rate predicted by logistic regression after 5 days of mechanical ventilation. The overall survival rate was 18 (50.0%) of 36 patients. CONCLUSIONS In severe acute respiratory failure treated with lung rest and extracorporeal life support, a predicted 50% mortality rate was associated with 5 days of preextracorporeal life support mechanical ventilation.

Abstract
Extracorporeal membrane oxygenation (ECMO) has had promising results in life-threatening respiratory failure and postcardiotomy cardiogenic failure. From October 1994 to October 1995, 18 patients received 19 ECMOs at National Taiwan University Hospital for severe cardiogenic shock after cardiac surgery. They included patients receiving cardiac massage or repeated bolus injections of norepinephrine to maintain blood pressure (n = 10), patients who could not be weaned off cardiopulmonary bypass after several attempts despite intraaortic balloon pumping and maximal doses of catecholamine (n = 7), and patients with progressive intractable cardiogenic shock after cardiac surgery. Venoarterial ECMO was set up via femoral artery (17 or 19 Fr cannula) and vein (19 or 21 Fr) in all patients except 2 infants. No left heart drainage was performed in any of the patients. The heparin-coated circuit (with Carmeda Bio-active Surface) was used in the last 13 patients to reduce bleeding. Ten (52.6%) of the 19 cases could be smoothly weaned off ECMO, and 6 (33.3%) of the 18 patients were discharged from the hospital in good condition. Four (80%) of the 5 patients after valvular surgery and all 3 heart transplant patients could be weaned off ECMO successfully with the survival rate being 60% and 67%, respectively. Complications included leg ischemia (n = 3), bleeding (n = 4), renal failure (n = 3), and tube rupture (n = 1). The inability to wean off ECMO was caused by multiple organ failure (n = 5), sepsis (n = 2), tube rupture (n = 1), and dysfunction of the ECMO system (n = 1). The major cause of multiple organ failure was hesitation to set up ECMO. Our preliminary results confirmed the effect of ECMO in postoperative cardiogenic shock.

Abstract
Over the past several years, the use of venovenous extracorporeal membrane oxygenation (ECMO) has increased. The primary advantage of venovenous (VV) over venoarterial (VA) ECMO is preservation of the carotid artery. Its primary disadvantage is that it does not provide circulatory support. While VV ECMO is technically similar to VA ECMO, clinical application of VV ECMO is quite different from VA ECMO. Recent clinical data show that VV ECMO is safe and effective. The purpose of this review is to discuss these differences between VV and VA ECMO, to review the various forms of VV ECMO, and finally to offer recommendations on the safe clinical use of VV ECMO.

Abstract
Despite advances in respiratory and critical care medicine, the mortality from ARDS remains unchanged. Recent research suggests current ventilatory therapy may produce additional lung injury, retarding the recovery process of the lung. Alternative supportive therapies, such as ECMO and ECCO2R, ultimately may result in less ventilator induced lung injury. Due to the invasiveness of ECMO/ECCO2R, these modalities are initiated reluctantly and commonly not until patients suffer from terminal or near-terminal respiratory failure. Low flow ECCO2R may offer advantages of less invasiveness and be suitable for early institution before ARDS becomes irreversible. We describe a patient with ARDS and severe macroscopic barotrauma supported with low flow ECCO2R resulting in significant CO2 clearance, reduction of peak, mean airway pressures and minute ventilation.

Abstract
STUDY OBJECTIVE To characterize the physiologic response to, and safety of, intravenacaval membrane oxygenation and carbon dioxide removal. DESIGN Interventional before-after study. SETTING University teaching hospital ICU. PATIENTS Twenty-two patients with severe acute respiratory distress syndrome (ARDS). INTERVENTIONS Implantation of a hollow-fiber membrane oxygenator (IVOX; CardioPulmonics; Salt Lake City, Utah) into the superior and inferior venae cavae by venotomy of the right femoral or right internal jugular vein for a duration of up to 20 days. MEASUREMENTS Hemodynamic measurements using pulmonary artery and systemic artery catheters, ventilator settings (FIO2, minute ventilation, peak inspiratory pressure, and positive end-expiratory pressure), arterial and mixed venous blood gases (pH, PCO2, PO2, and measured saturation), and clinical laboratory determinations (CBC, fibrinogen, plasma hemoglobin, complement C3 and C5) were obtained. Calculations of PaO2/FIO2 ratio and PaCO2-VE product were used to assess gas exchange efficacy. Microbiologic cultures were obtained from the device and wound following explantation. Survival to ICU discharge and hospital discharge were recorded. RESULTS Implantation was successful in 20 of 22 patients. Gas exchange rates averaged 50.4 +/- 15.8 mL.min-1 for carbon dioxide and 71.1 +/- 20.2 mL.min-1 for oxygen. A reduction in FIO2 from 0.78 +/- 0.16 to 0.63 +/- 0.21 and in VE from 177 +/- 94 mL.kg-1.min-1 to 127 +/- 58 mL.kg-1.min-1 was possible within 4 h post-implantation. By 12 h, FIO2 was reduced to 0.57 +/- 0.18. Indices of gas exchange improved significantly after implantation, with PaO2/FIO2 ratio increasing from 79 +/- 20 to 112 +/- 47 and PaCO2-VE product decreasing from 7.6 +/- 4.2 to 4.9 +/- 2.5 within 4 h. A significant reduction in peak inspiratory pressure was achieved (45 +/- 10 to 38 +/- 9 cm H2O). Major complications were blood loss during implantation requiring transfusion in 11 patients, a retroperitoneal bleed in 1 patient, and femoral deep venous thrombosis in 4 patients, but there were no long-term sequelae or IVOX-related deaths. The ICU and hospital survival were 10/20 (50%) and 8/20 (40%), respectively. CONCLUSIONS Intravenacaval membrane oxygen and carbon dioxide removal can provide partial respiratory support during severe respiratory failure and permit reductions in the level of mechanical ventilator support, with an acceptable safety profile.

Abstract
Extracorporeal life support (ECLS) has been used in 10 patients after heart (5 patients), lung (3 patients), and heart-lung (2 patients) transplantation. The age range was 7 months to 55 years. Cardiopulmonary failure leading to institution of ECLS was due to acute postoperative organ malfunction in 4 patients (2 survived), subacute organ malfunction in 3 patients (none survived), and late rejection or infection in 3 patients (2 survived). Neurologic complications occurred in 3 patients (1 survived) and bleeding, in 5 patients (2 survived). Six patients (60%) were successfully weaned from ECLS, and 4 (40%) survived to leave the hospital. Survival was associated with younger age, shorter duration of ECLS, and longer interval from operation to initiation of ECLS but not to reason for initiating ECLS. Extracorporeal life support is feasible for sustaining both adults and children after heart, lung, or heart-lung transplantation. Best results were obtained in patients with conditions that, in retrospect, were treatable and reversible within days. More experience is needed to predict preoperatively which patients will benefit most from ECLS.

Abstract
Extracorporeal life support (ECLS) is a recognized treatment for neonatal respiratory distress unresponsive to other forms of therapy. Variations of this technique are being developed in an effort to extend its applicability and safety. Extracorporeal CO2 removal (ECCO2R) is one such modification that requires blood flows of 20% to 50% of cardiac output and therefore lends itself to percutaneous venous cannulation. The authors evaluated ECCO2R in conjunction with low-frequency ventilation, using a lung lavage-induced model of respiratory failure in rabbits. Six rabbits were lavaged an average of 9 times with 15 mL/kg Plasma-Lyte A at 37 degrees C via an endotracheal tube. Incremental ventilatory changes were made during lavage, to an FIO2 of 1.0, rate of 80, peak inspiratory pressure (PIP) of 37 cm H2O, and positive end-expiratory pressure (PEEP) of 4 cm H2O. Arterial blood gas values of PaO2 < 40 mm Hg and PaCO2 > 60 mm Hg resulted, meeting our criteria for respiratory failure. The rabbits were placed on veno-venous ECCO2R using a 0.8-m2 hollow fiber oxygenator and a commercially available double-lumen dialysis catheter. Blood flows of 10 to 20 mL/kg/min were used to manage CO2 removal. A low-frequency ventilation technique was employed using an FIO2 of 1.0 and a rate of 5 breaths per minute. PEEP was increased incrementally to maintain the PaO2 above 80 mm Hg. After initiation of ECCO2R, the arterial PaO2 increased to 165 +/- 109 mm Hg, with PEEP above 15 cm H2O, and PaCO2 decreased to 37 +/- 5 mm Hg, with a bypass flow rate of 15 mL/kg/min.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Survival from reversible forms of severe pulmonary insufficiency remains dismal despite the development of artificial oxygenators. We hypothesized that an intraabdominal heterotopic lung could help maintain adequate oxygenation during acute pulmonary insufficiency. Five mongrel dogs underwent an acute heterotopic lung transplant (HLT). The left atrial cuff was anastomosed to the inferior vena cava, and the left pulmonary artery was anastomosed to the abdominal aorta. The trachea was exteriorized, intubated, and ventilated with a volume-controlled ventilator. Ventilation to the native lungs was discontinued. The heterotopic lung was then ventilated at a rate of 20/min, tidal volume of 15 ml/kg, and inspired concentration (FIO2) of 50 percent. Partial pressure of oxygen (PO2) and mixed venous oxygen saturation (SvO2) were maintained at 53 +/- 5.2 mm Hg and 71 +/- 12 percent, respectively. Flow through the HLT was approximately 20 percent of the systemic cardiac output and did not vary with changes in FIO2, respiratory rate, or positive end-expiratory pressure (PEEP). Four separate animals underwent HLT and were studied 2 to 3 days later. The FIO2 was reduced in the native lungs to 10 percent until SaO2 was less than 90 percent. The HLT was then ventilated at a tidal volume of 300 ml, an FIO2 of 50 percent, and a respiratory rate of 10. Arterial PO2 increased from 62 +/- 4 mm Hg to 75 +/- 2 mm Hg, and SvO2 increased from 75 +/- 2 percent to 82 +/- 3 percent (p < 0.05). Flow through the HLT increased slightly to 27 percent of the systemic cardiac output. We conclude that a HLT can augment oxygenation after induction of moderate hypoxemia, but cannot serve as the sole source for gas exchange because flow through the HLT is limited to less than 30 percent of the cardiac output.

Abstract
The need for improvements in materials and equipment for extracorporeal circulation has been obvious for years. Among the surfaces with biologically active compounds, those with heparin binding have been found sufficiently thromboresistant and particularly suitable for different types of artificial perfusion. Partial left heart bypass (LHBP) was performed in 10 anesthetized, acutely instrumented, and open-chested mongrel dogs (weight 23 to 50 kg) with a servo-controlled roller pump. The pump flow was maintained at 50 mL/kg/min for 6 hours. Heparin surface-coated equipment was used without additional heparin. For LHBP with a standard circuit, the total amount of heparin during the study period was (mean +/- SD) 487 +/- 124 IU/kg. The right atrial, pulmonary artery, and left ventricular end-diastolic pressures, cardiac output, left ventricular output, right and left ventricular stroke work, pulmonary gas exchange, and acid-base balance changed similarly with both systems. Blood loss (204 +/- 78 v 1,240 +/- 586 mL, P < 0.0005), volume substitution requirements (647 +/- 48 v 1,860 +/- 764 mL, P < 0.0025), and oxygen extraction ratio (mean 25.4 to 32.0 v 25.4 to 56.4%, P < 0.025) were significantly lower, and mean aortic pressure (mean 65 to 69 v 62 to 38 mmHg, P < 0.025) and hemoglobin concentration (mean 9.1 to 8.1 v 9.4 to 3.9 g/dL, P < 0.05) were significantly higher during 6 hours of LHBP without systemic heparinization. Low but stable oxygen delivery was provided with heparin-coated LHBP, whereas it showed a descending trend (mean 14.0 to 10.8 v 13.4 to 5.5 mL/kg/min, P < 0.1) with the standard circuit.(ABSTRACT TRUNCATED AT 250 WORDS)
