Comparison of 1 month postintervention to preintervention, generalized knowledge improved by a minimum of 38% for each question and competency increased by over 50%. From this study comes the recommendation that VAD centers must include the community first responders as part of their discharge planning for the VAD patient and improve community outreach to ensure appropriate patient outcomes.Mechanical assist devices in refractory cardiac arrest are increasingly employed. We compared the hemodynamics and organ perfusion during cardiac arrest with either veno-arterial extracorporeal membrane oxygenation (ECMO) or biventricular assisted circulation combining left- and right-sided impeller devices (BiPella) in an acute experimental setting. Twenty pigs were randomized in two equal groups receiving circulatory support either by ECMO or by BiPella during 40 minutes of ventricular fibrillation (VF) followed by three attempts of cardioversion, and if successful, 60 minute observation with spontaneous, unsupported circulation. Hemodynamic variables were continuously recorded. Tissue perfusion was evaluated by fluorescent microsphere injections. Cardiac function was visualized by intracardiac echocardiography. During VF device output, carotid flow, kidney perfusion, mean aortic pressure (AOPmean), and mean left ventricular pressure (LVPmean) were all significantly higher in the ECMO group, and serum-lactate values were lower compared with the BiPella group. No difference in myocardial or cerebral perfusion was observed between groups. In 15 animals with sustained cardiac function for 60 minutes after return of spontaneous circulation, left ventricular subendocardial blood flow rate averaged 0.59 ± 0.05 ml/min/gm during VF compared with 0.31 ± 0.07 ml/min/gm in five animals with circulatory collapse (p = 0.005). Corresponding values for the midmyocardium was 0.91 ± 0.06 vs. 0.65 ± 0.15 ml/min/gm (p = 0.085). Both BiPella and ECMO could sustain vital organ function. ECMO provided a more optimal systemic circulatory support related to near physiologic output. Myocardial tissue perfusion and sustained cardiac function were related to coronary perfusion pressure during VF, irrespective of mode of circulatory support.Continuous bedside pulse oximetry (SpO2) is universally used to monitor oxygenation for patients supported on veno-venous extracorporeal membrane oxygenation (VV-ECMO).  https://www.selleckchem.com/products/sndx-5613.html  Yet, elevated carboxyhemoglobin (COHb), a known event in VV-ECMO, diminishes the reliability of SpO2. This retrospective cohort study aims to assess the accuracy of SpO2 compared with oxyhemoglobin (SaO2) and quantify COHb levels by co-oximetry in the VV-ECMO population. Forty patients on VV_ECMO from 2012 to 2017 underwent 1,119 simultaneous SaO2 and SpO2 measurements. Most patients were male (60%) with average age of 46 years. SpO2 overestimated SaO2 values by 2.35% at time of cannulation and 0.0061% for each additional hour on VV-ECMO (p 3% of hemoglobin saturation) at least once during VV-ECMO support and 602 (40.2%) arterial blood gases yielded elevated COHb levels. Mean duration for ECMO with elevated COHb was 244 hours compared with 98 hours in patients without (p less then 0.0048). Patients who developed COHb were younger (mean age 40 vs. 55 years, p less then 0.024) and had single-site double-lumen cannulation (odds ratio = 4.5, p = 0.23). At time of cannulation, mean COHb was 2.18% and increased by 0.0054% for each additional hour (p less then 0.0001). For every 1% increase in COHb, SaO2 decreased by 1.1% (p less then 0.0001). During VV-ECMO, SpO2 often overestimates SaO2 by substantial margins. This is attributable to rising COHb levels proportional to duration on VV-ECMO. In this population where adequate oxygen delivery is often marginal, clinicians should be wary of the reliability of continuous pulse oximetry to assess oxygenation.Patients with adult congenital heart disease (ACHD) who undergo cardiac surgery may require extracorporeal life support (ECLS) for cardiopulmonary support, but outcomes after ECLS support have not been well described. This study aimed to identify risk factors for ECLS mortality in this population. We identified 368 ACHD patients who received ECLS after cardiac surgery between 1994 and 2016 in the Extracorporeal Life Support Organization (ELSO) database, a multicenter international registry of ECLS centers. Risk factors for mortality were assessed using multivariate logistic regression. Overall mortality was 61%. In a multivariate model using precannulation characteristics, Fontan physiology (odds ratio [OR] 5.7; 95% CI 1.6-20.0), weight over 100 kg (OR 2.6; 95% CI 1.3-5.4), female gender (OR 1.6; 95% CI 1.001-2.6), delayed ECLS cannulation (OR 2.0; 95% CI 1.2-3.2), and neuromuscular blockade (OR 1.9; 95% CI 1.1-3.3) were associated with increased mortality. Adding postcannulation characteristics to the model, renal complications (OR 3.0; 95% CI 1.7-5.2), neurologic complications (OR, 4.7; 95% CI 1.5-15.2), and pulmonary hemorrhage (OR 6.4; 95% CI 1.3-33.2) were associated with increased mortality, whereas Fontan physiology was no longer associated, suggesting the association of Fontan physiology with mortality may be mediated by complications. Fontan physiology was also a risk factor for neurologic complications (OR 8.2; 95% CI 3.3-20.9). Given the rapid increase in ECLS use, understanding risk factors for ACHD patients receiving ECLS after cardiac surgery will aid clinicians in decision-making and preoperative planning.The number of patients with left ventricular assist devices (LVAD) has increased over the years and it is important to identify the etiologies for hospital admission, as well as the costs, length of stay and in-hospital complications in this patient group. Using the National Readmission Database from 2010 to 2015, we identified patients with a history of LVAD placement using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code V43.21. We aimed to identify the etiologies for hospital admission, patient characteristics, and in-hospital outcomes. We identified a total of 15,996 patients with an LVAD, the mean age was 58 years and 76% were males. The most common cause of hospital readmission after LVAD was heart failure (HF, 13%), followed by gastrointestinal (GI) bleed (11.8%), device complication (11.5%), and ventricular tachycardia/fibrillation (4.2%). The median length of stay was 6 days (3-11 days) and the median hospital costs was $12,723 USD. The in-hospital mortality was 3.
