Objectives: Extracorporeal cardiopulmonary resuscitation (eCPR) is increasingly used due to its beneficial outcomes and results compared with conventional CPR. Data after eCPR for acute kidney injury (AKI) are lacking. We sought to investigate factors predicting AKI in patients who underwent eCPR., Methods: From January 2016 until December 2020, patients who underwent eCPR at our institution were retrospectively analyzed and divided into two groups: patients who developed AKI ( n  = 60) and patients who did not develop AKI ( n  = 35) and analyzed for outcome parameters., Results: Overall, 63% of patients suffered AKI after eCPR and 45% of patients who developed AKI needed subsequent dialysis. Patients who developed AKI showed higher values of creatinine (1.1 mg/dL vs 1.5 mg/dL, p ⩽ 0.01), urea (34 mg/dL vs 42 mg/dL, p = 0.04), CK (creatine kinase) (923 U/L vs 1707 U/L, p = 0.07) on admission, and CK after 24 hours of ECMO support (1705 U/L vs 4430 U/L, p = 0.01). ECMO explantation was significantly more often performed in patients who suffered AKI (24% vs 48%, p = 0.01). In-hospital mortality (86% vs 70%; p = 0.07) did not differ significantly., Conclusion: Patients after eCPR are at high risk for AKI, comparable to those after conventional CPR. Baseline urea levels predict the development of AKI during the hospital stay.

Background: Gender is known to influence the pathophysiology and pathogenesis of the coronary vascular disease. Data on gender-related differences in patients with veno-arterial extracorporeal membrane oxygenation due to postcardiotomy cardiogenic shock is lacking in current literature. We aimed to analyze the impact of gender on intraoperative and short-term outcomes of vaECMO patients after coronary surgery and postcardiotomy cardiogenic shock., Methods: Between 2006 and 2017, a total of 92 patients with PCS after CABG underwent vaECMO-implantation at our institution. After a 1:1 propensity score match (PSM) for relevant preoperative data, we identified a cohort of 32 patients, 16 males, and 16 females. Periprocedural and short-term outcome data were analyzed with respect to sex differences., Results: The mean age was 64 ± 11 years, and 79% ( n  = 73) were male patients. Clinical outcomes showed a 30-day all-cause mortality of 64% ( n  = 59). After PSM, male patients showed a significantly smaller number of arterial grafts (0.4 ± 0.53 male vs 1.1 ± 0.7 female; p = 0.037). Thirty-day all-cause mortality did not differ between the groups (56% male vs 75% female; p = 0.262). In general, short-term outcome data were comparable without significant differences for the matched groups., Conclusion: Gender has no impact on patients with vaECMO therapy due to PCS in isolated coronary surgery.

Background and Objectives: Pediatric extracorporeal membrane oxygenation (ECMO) support is often the ultimate therapy for neonatal and pediatric patients with congenital heart defects after cardiac surgery. The impact of lactate clearance in pediatric patients during ECMO therapy on outcomes has been analyzed. Materials and Methods: We retrospectively analyzed data from 41 pediatric vaECMO patients between January 2006 and December 2016. Blood lactate and lactate clearance have been recorded prior to ECMO implantation and 3, 6, 9 and 12 h after ECMO start. Receiver operating characteristic (ROC) analysis was used to identify cut-off levels for lactate clearance. Results: Lactate levels prior to ECMO therapy (9.8 mmol/L vs. 13.5 mmol/L; p = 0.07) and peak lactate levels during ECMO support (10.4 mmol/L vs. 14.7 mmol/L; p = 0.07) were similar between survivors and nonsurvivors. Areas under the curve (AUC) of lactate clearance at 3, 9 h and 12 h after ECMO start were significantly predictive for mortality ( p = 0.017, p = 0.049 and p = 0.006, respectively). Cut-off values of lactate clearance were 3.8%, 51% and 56%. Duration of ECMO support and respiratory ventilation was significantly longer in survivors than in nonsurvivors ( p = 0.01 and p < 0.001, respectively). Conclusions: Dynamic recording of lactate clearance after ECMO start is a valuable tool to assess outcomes and effectiveness of ECMO application. Poor lactate clearance during ECMO therapy in pediatric patients is a significant marker for higher mortality.

The aim of this study was to provide early and mid-term results of the newly established extracorporeal membrane oxygenation (ECMO) retrieval service in a tertiary cardiothoracic center using the miniaturized portable Cardiohelp System (Maquet, Rastatt, Germany). A particular attention was paid to organizational and logistic specifics as well as challenges and pitfalls associated with initial phase of the program. From January 2015 until January 2017 a heterogenic group of 28 consecutive patients underwent ECMO implantation in distant hospitals for acute cardiac, pulmonary or combined failure as a bridge-to-decision and were subsequently transported to our institution. Each cannulation was performed bedside on intensive care units (ICU) using the Seldinger's technique. Early outcomes and mid-term overall survival with up to two-year follow-up along with the impact of ongoing cardiopulmonary resuscitation (CPR) on outcome were presented. Also, changes in hemodynamics and tissue perfusion factors 24 h after ECMO implantation were evaluated. ECMO implantations were performed in 15 distant departments with the median distance of 23(10;40) (maximum 60) km. A total of 15 patients (54%) were cannulated under CPR with the median duration of 30(20;110) (maximum 180) min. After 24 h of support there were significant improvements in SvO 2 (P = 0.021), mean arterial pressure (P = 0.027), FiO 2 (P = 0.001), lactate (P = 0.001), and pH (P < 0.001). The mean ECMO support duration was 96 ± 100 (maximum 384) hours, whereas 11 patients (40%) were weaned off support and discharged from hospital. Overall cumulative survival in patients without the need for CPR was 61.5% at one week and 38.5% at 1 month, 6 month, and 1 year, whereas patients requiring CPR survived in 40% at one week, and 33.3% at 1 month, 6 month, and 1 year (Log-Rank (Mantel-Cox) P = 0.374, Breslow (Generalized Wilcoxon) P = 0.162). Our initial experience shows that launching new ECMO retrieval programs in centers with sufficient ICU capacities and local ECMO experience can be feasible and associated with acceptable "real world" results despite the initial learning curve. Rapid logistical organization and team flexibility are the key points to ensure comparable survival of patients requiring prolonged CPR., (© 2017 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.)

Introduction: Extracorporeal life support emerged as a salvage option in patients with therapy-refractory severe hemodynamic or respiratory failure. However, this promising therapy option has been limited by the use of experienced teams in highly specialized tertiary-care centers. Thus, in order to provide this standard of care in local hospitals and due to increasing evidence on improved outcomes using ECMO devices and setting for patients with heart and lung failure, an increasing number of experienced ECMO centers have launched mobile ECMO retrieval services in recent years. Areas covered: This review provides a summary on the current scientific status concerning use, indications and complications of mobile ECMO devices and services. A scientific literature research was conducted in MEDLINE, Embase, Cochrane and Web of Science databases using keywords denoted. Expert commentary: Mobile ECMO devices and setting offer severely ill patients refractory to maximal conventional treatment an option of hemodynamic and/or respiratory stabilization and subsequent transportation to specialized care centers for further treatment. Compared to in-hospital ECMO support, out-of-hospital mobile ECMO implantation, transport and retrieval of patients require additional organizational, logistical and clinical efforts. This review provides a summary on the current scientific status concerning use, indications and complications of mobile ECMO services.
