ABSTRACT: Aims
Knowledge about the impact of epinephrine on the outcome in venoarterial (VA) extracorporeal membrane oxygenation (ECMO) patients is limited, and existing data are conflicting.Methods and results
We conducted a retrospective cohort study in a 1500 bed tertiary university hospital. Five hundred and eighty-nine VA-ECMO patients were analysed. The median age was 57 years [47-65], 68% of male. The major indications for ECMO were post-cardiotomy cardiogenic shock (CS) (38%) and medical CS (36%). Two hundred and sixty-two (44.5%) patients received epinephrine alone or associated with another catecholamine while on ECMO. Baseline factors significantly associated with epinephrine administration were younger age, higher sequential organ failure assessment score, cardiac arrest at implantation, and intra-aortic balloon pump support at implantation, whereas medical CS and dobutamine administration were significantly associated with a lower risk of epinephrine administration. Epinephrine administration was independently associated with death [hazard ratio = 1.68 (1.44-2.23); P < 0.01]. A sensitivity analysis with propensity score inverse probability weighting in complete cases confirmed a significant association of epinephrine administration with death [hazard ratio = 1.69 (1.43-2.00); P < 0.001].Conclusions
Among patients who required VA-ECMO, epinephrine administration was associated with an increased risk for death.

Project description:Cardiogenic shock and cardiac arrest contribute pre-dominantly to mortality in acute cardiovascular care. Here, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has emerged as an established therapeutic option for patients suffering from these life-threatening entities. VA-ECMO provides temporary circulatory support until causative treatments are effective and enables recovery or serves as a bridging strategy to surgical ventricular assist devices, heart transplantation or decision-making. However, in-hospital mortality rate in this treatment population is still around 60%. In the recently published ARREST trial, VA-ECMO treatment lowered mortality rate in patients with ongoing cardiac arrest due to therapy refractory ventricular fibrillation compared to standard advanced cardiac life support in selected patients. Whether VA-ECMO can reduce mortality compared to standard of care in cardiogenic shock has to be evaluated in the ongoing prospective randomized studies EURO-SHOCK (NCT03813134) and ECLS-SHOCK (NCT03637205). As an innate drawback of VA-ECMO treatment, the retrograde aortic flow could lead to an elevation of left ventricular (LV) afterload, increase in LV filling pressure, mitral regurgitation, and elevated left atrial pressure. This may compromise myocardial function and recovery, pulmonary hemodynamics-possibly with concomitant pulmonary congestion and even lung failure-and contribute to poor outcomes in a relevant proportion of treated patients. To overcome these detrimental effects, a multitude of venting strategies are currently engaged for both preventive and emergent unloading. This review aims to provide a comprehensive and structured synopsis of existing venting modalities and their specific hemodynamic characteristics. We discuss in detail the available data on outcome categories and complication rates related to the respective venting option.

Project description:BACKGROUND:Venoarterial extracorporeal membrane oxygenation (VA-ECMO) can be a rescue therapy for patients in cardiogenic shock or in refractory cardiac arrest. After cannulation, vasoplegia and cardiac depression are frequent. In literature, there are conflicting data on inotropic therapy in these patients. METHODS:Analysis of a retrospective registry of all patients treated with VA-ECMO in a university hospital center between October 2010 and December 2018 for cardiogenic shock or extracorporeal cardiopulmonary resuscitation (eCPR) with a focus on individual early inotropic therapy. RESULTS:A total of 231 patients (age 58.6 ± 14.3, 29.9% female, 58% eCPR, in-house survival 43.7%) were analyzed. Of these, 41.6% received no inotrope therapy within the first 24 h (survival 47.9%), 29.0% received an inodilator (survival 52.2%), and 29.0% received epinephrine (survival 25.0%). Survival of patients with epinephrine was significantly worse compared to other patient groups when evaluating 30-day survival (p = 0.034/p = 0.005) and cumulative incidence of in-hospital death (p = 0.001). In a multivariate logistic regression analysis, treatment with epinephrine was associated with mortality in the whole cohort (OR 0.38, p = 0.011) as well as after propensity score matching (OR 0.24, p = 0.037). We found no significant differences between patients with inodilator treatment and those without. CONCLUSION:Early epinephrine therapy within the first 24 h after cannulation for VA-ECMO was associated with poor survival compared to patients with or without any inodilator therapy. Until randomized data are available, epinephrine should be avoided in patients on VA-ECMO.

Project description:Spinal cord infarction (SCI) is a rare disease among central nervous system vascular diseases. Only a little is known about venoarterial extracorporeal membrane oxygenation (VA-ECMO)-related SCI. Retrospective observational study conducted, from 2006 to 2019, in a tertiary referral center on patients who developed VA-ECMO-related neurovascular complications, focusing on SCI. During this period, among the 1893 patients requiring VA-ECMO support, 112 (5.9%) developed an ECMO-related neurovascular injury: 65 (3.4%) ischemic strokes, 40 (2.1%) intracranial bleeding, one cerebral thrombophlebitis (0.05%) and 6 (0.3%) spinal cord infarction. Herein, we report a series of six patients with refractory cardiogenic shock or cardiac arrest receiving circulatory support with VA-ECMO who developed subsequent SCI during ECMO course, confirmed by spine MRI after ECMO withdrawal. All six patients had long-term neurological disabilities. VA-ECMO-related SCI is a rare but catastrophic complication. Its diagnosis is usually delayed due to sedation requirement and/or ICU acquired weakness after sedation withdrawal, leading to difficulties in monitoring their neurological status. Even if no specific treatment exist for SCI, its prompt diagnosis is mandatory, to prevent secondary spine insults of systemic origin. Based on these results, we suggest that daily sedation interruption and neurological exam of the lower limbs should be performed in all VA-ECMO patients. Large registries are mandatory to determine VA-ECMO-related SCI risk factor and potential therapy.

Project description:ObjectivesTo evaluate the clinical outcomes and perioperative complications associated with complete percutaneous decannulation of femoral venoarterial extracorporeal membrane oxygenation (VA-ECMO) with the MANTA closure device.MethodsThis is a retrospective analysis of a single surgeon consecutive series of 14 patients at a single center who underwent decannulation from VA-ECMO, 10 of whom underwent a percutaneous method of femoral cannula removal.ResultsAfter a mean duration of VA-ECMO support of 7.4 ± 3.8 days, all 10 patients, with arterial cannulas ranging in size from 17 to 21 Fr, underwent percutaneous decannulation with the MANTA closure device, with immediate hemostasis. One patient had acute lower limb ischemia that was recognized intraoperatively and successfully treated with suction embolectomy. Two patients had a pseudoaneurysm at the distal perfusion catheter site recognized on perioperative imaging studies, one resolving with observation and the other necessitating thrombin injection. One patient had a hematoma that resolved with observation.ConclusionsPercutaneous decannulation from VA-ECMO using the MANTA large-bore vascular closure device is feasible and results in immediate hemostasis with excellent angiographic results.

Project description:No major study has been performed on the conversion from venovenous (VV) to venoarterial (VA) extracorporeal membrane oxygenation (ECMO) in adults. This single-center retrospective cohort study aimed to investigate the incidence, indication, and outcome in patients who converted from VV to VA ECMO. All adult patients (≥18 years) who commenced VV ECMO at our center between 2005 and 2018 were screened. Of 219 VV ECMO patients, 21% (n = 46) were converted to VA ECMO. The indications for conversion were right ventricular failure (RVF) (65%), cardiogenic shock (26%), and other (9%). In the converted patients, there was a significant increase in Sequential Organ Failure Assessment (SOFA) scores between admission 12 (9-13) and conversion 15 (13-17, p < 0.001). Compared to non-converted patients, converted patients also had a higher mortality rate (62% vs. 16%, p < 0.001) and a lower admission Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) score (p < 0.001). Outcomes were especially unfavorable in those converted due to RVF. These results indicate that VA ECMO, as opposed to VV ECMO, should be considered as the first mode of choice in patients with respiratory failure and signs of circulatory impairment, especially in those with impaired RV function. For the remaining patients, Pre-admission RESP score, daily echocardiography, and SOFA score trajectories may help in the early identification of those where conversion from VV to VA ECMO is warranted. Multi-centric studies are warranted to validate these findings.

Project description:BACKGROUND:Structural neurological complications (ischemic stroke and intracranial bleeding) and their risk factors in patients receiving venoarterial-extracorporeal membrane oxygenation (VA-ECMO) are poorly described. Our objective was to describe frequencies, outcomes and risk factors for neurological complications (ischemic stroke and intracranial bleeding) in patients receiving VA-ECMO. METHODS:Retrospective observational study conducted, from 2006 to 2014, in a tertiary referral center on patients who developed a neurological complication(s) on VA-ECMO. RESULTS:Among 878 VA-ECMO-treated patients, 65 (7.4%) developed an ECMO-related brain injury: 42 (5.3%) ischemic strokes and 20 (2.8%) intracranial bleeding, occurring after a median [25th;75th percentile] of 11 [6;18] and 5 [2;9] days of support, respectively. Intracranial bleeding but not ischemic stroke was associated with higher mortality. Multivariable analysis retained only platelet level?>?350 giga/L as being associated with ischemic stroke. Female sex, central VA-ECMO and platelets?<?100 giga/L at ECMO start were independently associated with intracranial bleeding with respective odds ratios [95% CI] of 2.9 [1.1-7.5], 3.8 [1.1-10.2] and 3.7 [1.4-9.7]. In a nested case-control study, rapid CO2-level change from before-to-after ECMO start also seemed to be associated with intracranial bleeding. CONCLUSIONS:Neurological events are frequent in VA-ECMO-treated patients. Ischemic stroke is the most frequent, occurs after 1 week on ECMO support, has no specific risk factor and is not associated with higher mortality. Intracranial bleeding occurs earlier and is associated with female sex, central VA-ECMO, low platelet count and rapid CO2 change at ECMO start, and high mortality. LEVEL OF EVIDENCE:This study provides Class IV evidence that central VA-ECMO, low platelet count and rapid CO2 change at ECMO start are associated with intracranial bleeding and high mortality.

Project description:BackgroundStudies reporting long-term outcomes of venoarterial extracorporeal membrane oxygenation-treated coronary artery bypass grafting patients are scarce. The objective of this study was to examine the survival outcomes and identify mortality risk factors for coronary artery bypass grafting patients who received venoarterial extracorporeal membrane oxygenation for postcardiotomy cardiogenic shock.MethodsData from 121 consecutive venoarterial extracorporeal membrane oxygenation-treated coronary artery bypass grafting patients at the Beijing Anzhen Hospital between January 2012 and December 2016 were analyzed. Multivariable Cox regression modeling was used to identify factors independently associated with 36-month mortality.ResultsSeventy-seven patients (64%) could be weaned from venoarterial extracorporeal membrane oxygenation, 56 patients (46%) survived to hospital discharge, and 41 patients (34%) survived to 36 months. Older age (hazard ratio, 1.06; 95% confidence interval [CI], 1.03-1.10; p < 0.001), left main coronary artery disease (hazard ratio, 1.64; 95% CI, 1.04-2.59; p < 0.001), and vasoactive inotropic score (hazard ratio, 1.09; 95% CI, 1.02-1.16; p = 0.011) were independent risk factors associated with 36-month mortality. The area under the receiver operating characteristic curve for the logistic regression model, which was constructed with three pre-extracorporeal membrane oxygenation parameters-age ⩾ 60 years, left main coronary artery disease, and vasoactive inotropic score > 60-was 0.87 (95% CI, 0.81-0.94). Age and left main coronary artery disease significantly increased the discriminatory performance of Sepsis-related Organ Failure Assessment score (0.79 vs. 0.91, p = 0.025).ConclusionsOlder age, left main coronary artery disease, and vasoactive inotropic score were associated with 36-month mortality in coronary artery bypass grafting patients who received venoarterial extracorporeal membrane oxygenation.

Project description:ObjectivesWe aimed to determine if elevations in serum neuron-specific enolase are associated with brain injury and outcomes in adults who require venoarterial extracorporeal membrane oxygenation.DesignProspective observational study.SettingTwo ICUs of a university hospital, Paris, France.PatientsConsecutive adult patients treated with venoarterial extracorporeal membrane oxygenation for refractory cardiogenic shock or in-hospital refractory cardiac arrest.InterventionsNone.Measurements and main resultsSerum sampled 1, 3, and 7 days after venoarterial extracorporeal membrane oxygenation cannulation was stored at -80°C and neuron-specific enolase concentrations were measured in batches at the end of the study. The association between neuron-specific enolase concentrations and outcomes (28-d mortality and poor outcome, defined by a score of 4-6 on the modified Rankin scale at 90 d) were explored by multivariable logistic regression, with neuron-specific enolase concentrations dichotomized according to median values. One-hundred three patients were included, of whom 26 (25%) received preextracorporeal membrane oxygenation cardiopulmonary resuscitation. Median (interquartile range) day-1, day-3, and day-7 neuron-specific enolase serum concentrations were 37 μg/L (26-51 μg/L), 25 μg/L (19-37) μg/L, and 22 μg/L (17-31 μg/L). After adjustment for Simplified Acute Physiology Score II, preextracorporeal membrane oxygenation cardiopulmonary resuscitation, and Sepsis Organ Failure Assessment score at time of cannulation, a day-3 neuron-specific enolase greater than 25 μg/L remained independently associated with 28-day mortality (adjusted odds ratio, 4.98; 95% CI, 1.86-13.32) and poor outcome at 90 days (adjusted odds ratio, 4.63; 95% CI, 1.81-11.84). A day-3 neuron-specific enolase threshold greater than 80 μg/L had a 100% specificity for prediction of both mortality (95% CI, 92-100%) and poor functional outcome (95% CI, 89-100%). In a subset of patients who underwent brain CT, neuron-specific enolase concentrations were significantly higher in patients diagnosed with stroke, as compared with those without stroke.ConclusionsIn adult patients under venoarterial extracorporeal membrane oxygenation, day-3 serum neuron-specific enolase concentrations are independently associated with short-term mortality and poor functional outcomes. These findings deserve validation in a multicenter setting.

Project description:Fibrinogen is a clotting factor and a major determinant of platelet aggregation. Albumin, on the other hand, inhibits platelet function and thrombus formation. Taken together, an elevated fibrinogen albumin ratio (FAR) has been described as a marker of disease severity during prothrombotic conditions. We evaluated the association of FAR and ischemic stroke during venoarterial extracorporeal membrane oxygenation (VA ECMO) support. A single center, retrospective study was performed including all adult patients placed on VA ECMO. FAR was calculated from fibrinogen and albumin measurements in the first 24 hours of VA-ECMO initiation. Patients were categorized into high (≥125) and low (<125) FAR groups and the risk of eventual ischemic stroke was determined. There were 201 patients who underwent VA ECMO placement and 157 had a FAR. They were 56 ± 14 years old and 66 (42%) had a high FAR. Patients with a high FAR had lower survival free from an ischemic stroke during VA ECMO (log rank p < 0.001; adjusted hazard ratio 5.51; 95% CI: 1.8-16.5). In tertile analysis, the level of FAR was associated with an incrementally higher likelihood of eventual ischemic stroke (log rank p = 0.004). Those with a high FAR had greater mean platelet volume (10.8[10.4-12] vs. 10.5[10.2-11.9]fl, p = 0.004). An elevated FAR during the first 24 hours of VA ECMO placement is associated with a greater risk of a subsequent ischemic stroke. Our findings suggest that assessment of FAR soon after VA ECMO placement may assist with early stratification of patients at risk for an ischemic stroke.
