Abstract
Nosocomial infections and thrombosis are frequent complications during extracorporeal membrane oxygenation (ECMO). Preventative measures and close monitoring for early recognition of these complications are imperative in patients supported with ECMO. We report the case of a 41 year old female on veno-venous ECMO awaiting surgical thrombectomy for chronic thromboembolic pulmonary hypertension that developed profound bacteremia leading to gross purulence and thrombosis of the membrane oxygenator. Recannulation in addition to targeted antibiotics, frequent cultures, imaging, and surgery were diagnostic and therapeutic interventions that led to ultimate resolution.

Abstract
BACKGROUND An increasing number of patients requires extracorporeal membrane oxygenation (ECMO) for life support. This supportive modality is associated with nosocomial infections (NIs). This systematic review and meta-analysis aim to assess the incidence and risk factors of NIs in adult. METHODS We searched PubMed, Scopus, Web of Science, and ProQuest databases up to 2022. The primary endpoint was incidence of NI. Secondary endpoints included time to infection, source of infection, ECMO duration, Intensive care and hospital length of stay (LOS), ECMO survival and overall survival. Incidence of NI was reported as pooled proportions and 95% confidence intervals (CIs), while dichotomous outcomes were presented as risk ratios (RR) as the effective index and 95% CIs using a random-effects model. RESULTS Among the 4,733 adult patients who received ECMO support in the 30 included studies, 1,249 ECMO-related NIs per 1000 ECMO-days was observed. The pooled incidence of NIs across 18 studies involving 3424 patients was 26% (95% CI 14-38%).Ventilator-associated pneumonia (VAP) and bloodstream infections (BSI) were the most common NI sources. Infected patients had lower ECMO survival and overall survival rates compared to non-infected patients, with risk ratio values of 0.84 (95% CI 0.74-0.96, P = 0.01) and 0.80 (95% CI 0.71-0.90, P < 0.001), respectively. CONCLUSION Results showed that 16% and 20% lower of ECMO survival and overall survival in patients with NI than patients without NI, respectively. However, NI increased the risk of in-hospital mortality by 37% in infected patients compared with non-infected patients. In addition, this study identified the significant positive correlation between ECMO duration and ECMO-related NI.

Abstract
BACKGROUND Neonates on extracorporeal membrane oxygenation (ECMO) are at high risk of infection. Rapid and accurate identification of pathogens is essential to improve the prognosis of children on ECMO. Metagenome next-generation sequencing (mNGS) has been used in recent years to detect pathogenic bacteria, but evidence for its use in neonates on ECMO is lacking. METHODS This retrospective study was conducted using an electronic medical record system. We analyzed the results of mNGS and conventional microbiological tests (CMTs) in bronchoalveolar lavage fluid of neonates receiving ECMO support with pulmonary infections in our hospital from July 2021 to January 2023. RESULTS We screened 18 ECMO-supported neonates with pneumonia for inclusion in the study. The median age of the included children was 2 (1-4) days, the median gestational age was 38.3 (33-40 +4 ) weeks, and the median weight was 3.3 (2.2-4.8) kg. The detection rate of mNGS was 77.8% (14/18), higher than the 44.4% (8/18) of CMT ( P = 0.04). A total of 20 pathogens were detected in mNGS, with the top 3 most common pathogens being Klebsiella pneumoniae , Acinetobacter baumannii and Escherichia coli . Mixed infections were found in 14 cases (77.8%), including 13 cases (72.2%) with mixed infections detected by mNGS and 7 cases (27.8%) with mixed infections detected by CMT. A total of 9 children underwent treatment changes based on mNGS results and all of them experienced relief of symptoms. CONCLUSION Compared with CMT, mNGS can detect pathogens earlier and more sensitively, and may play an important role in ECMO-supported neonatal pneumonia pathogen detection and optimization of antibiotic therapy.

Abstract
Patients with prolonged duration of extracorporeal membrane oxygenation support (ECMO) are a vulnerable population for sepsis, particularly ventilator-associated pneumonia and bloodstream infections. Rates differ between venous-arterial and venous-venous ECMO patients and according to the cannulation technique used. The presence of particular organisms depends on local epidemiology, antibiotic exposure, and the duration of the intervention; patients undergoing ECMO for more than three weeks present a high risk of persistent candidemia. Recognizing predisposing factors, and establishing the best preventive interventions and therapeutic choices are critical to optimizing the management of these complications. Infection control practices, including shortening the period of the indwelling devices, and reducing antibiotic exposure, must be followed meticulously. Innovations in oxygenator membranes require an updated approach. Hand hygiene and avoiding breaking the circuit-oxygenator sterility are cornerstones. ECMO management would benefit from clearer definitions, optimization of infection control strategies, and updated infectious clinical practice guidelines.

Abstract
INTRODUCTION After cardiac surgery, patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO) have a higher risk of nosocomial infection in the intensive care unit (ICU). We aimed to establish an intuitive nomogram to predict the probability of nosocomial infection in patients on VA-ECMO after cardiac surgery. METHODS We included patients on VA-ECMO after cardiac surgery between January 2011 and December 2020 at a single center. We developed a nomogram based on independent predictors identified using univariate and multivariate logistic regression analyses. We selected the optimal model and assessed its performance through internal validation and decision-curve analyses. RESULTS Overall, 503 patients were included; 363 and 140 patients were randomly divided into development and validation sets, respectively. Independent predictors derived from the development set to predict nosocomial infection included older age, white blood cell (WBC) count abnormality, ECMO environment in the ICU, and mechanical ventilation (MV) duration, which were entered into the model to create the nomogram. The model showed good discrimination, with areas under the curve (95% confidence interval) of 0.743 (0.692-0.794) in the development set and 0.732 (0.643-0.820) in the validation set. The optimal cutoff probability of the model was 0.457 in the development set (sensitivity, 0.683; specificity, 0.719). The model showed qualified calibration in both the development and validation sets (Hosmer-Lemeshow test, p > .05). The threshold probabilities ranged from 0.20 to 0.70. CONCLUSIONS For adult patients receiving VA-ECMO treatment after cardiac surgery, a nomogram-monitoring tool could be used in clinical practice to identify patients with high-risk nosocomial infections and provide an early warning.

Abstract
BACKGROUND Extracorporeal membrane oxygenation (ECMO) has been increasingly used in China, but nosocomial infections (NI) in patients receiving ECMO remain poorly characterized. Thus, this study aimed to investigate the incidence rate, causative was pathogens, and risk factors of NIs in ECMO patients. METHODS A retrospective cohort study of patients receiving ECMO between January 2015 and October 2021 was conducted in a tertiary hospital. General demographics and clinical data of the included patients were collected from the electronic medical record system and the real-time NI surveillance system. RESULTS A total of 86 infected patients with 110 episodes of NIs were identified in 196 patients receiving ECMO. The incidence of NI was 59.2/1000 ECMO days. The median time for the first NI in ECMO patients was 5 days (interquartile range: 2-8 days). Hospital-acquired pneumonia and bloodstream infections were common types of NIs in ECMO patients, and the main pathogens were gram-negative bacteria. Pre-ECMO invasive mechanical ventilation (OR = 2.40, 95% CI:1.12-5.15) and prolonged duration of ECMO (OR = 1.26, 95% CI:1.15-1.39) were risk factors for NIs during ECMO support. DISCUSSION This study identified the main infection sites and pathogens of NIs in ECMO patients. Although NIs may not affect successful ECMO weaning, additional measures should be implemented to reduce the incidence of NI during ECMO support.

Abstract
Bloodstream infections (BSI) are frequently encountered during extracorporeal membrane oxygenation (ECMO) support. Once septicemia is observed, treatment should be rapid, adequate, and multifaceted, particularly in advanced ECMO configurations. We report on a case of a 60-year-old male patient with acute-on-chronic heart failure due to ischemic cardiomyopathy. The treatment was complicated by cardiogenic shock requiring veno-arterial ECMO support, and, due to persistent pulmonary congestion, an upgrade with an additional left-atrial drainage cannula. After seven days of ECMO support, septicemia with shock ensued. Ex iuvantibus antibiotic treatment was started promptly. We wanted to minimize the likelihood of bacterial biofilm build-up requiring an exchange of the ECMO circuit and cannula, which was expected to be challenging. Therefore, we added a Seraph-100 Microbind affinity blood filter (providing blood purification with the potential for rapid bacterial clearance) to the ECMO circuit. Initial blood cultures tested positive for Enterobacter cloacae. Following a course of Seraph-100 treatment, bacteremia, septicemia, and shock resolved. There was no need for a circuit or cannula exchange. The additional eleven days of ECMO support were uneventful. The patient was successfully bridged to long-term mechanical circulatory support. We believe that the synergistic effect of early implementation of both broad-spectrum antibiotic treatment and blood purification with the potential for rapid bacterial clearance (such as the one provided with the Seraph-100 Microbind affinity blood filter) is crucial in BSI in patients receiving advanced ECMO.

Abstract
Objective There was no consensus on the impact of nosocomial infection on In-hospital mortality rate in patients receiving ECMO. This study aimed to investigate the impact of nosocomial infection (NI) on In-hospital mortality rate in adult patients receiving venoarterial extracorporeal membrane oxygenation (VA-ECMO) after cardiac surgery. Materials and Methods This retrospective study included 503 adult patients who underwent VA-ECMO after cardiac surgery. The impact of time-dependent NIs on In-hospital mortality rate within 28 days of ECMO initiation was investigated using a Cox regression model. The cumulative incidence function for death was compared between patients with NIs and those without NIs using a competing risk model. Results Within 28 days after ECMO initiation, 206 (41.0%) patients developed NIs, and 220 (43.7%) patients died. The prevalence rates of NIs were 27.8% and 20.3% during and after ECMO therapy, respectively. The incidence rates of NIs during and after ECMO therapy were 49‰ and 25‰, respectively. Time-dependent NI was an independent risk factor for predicting death (hazard ratio = 1.05, 95% confidence interval = 1.00-1.11). The cumulative incidence of death in patients with NI was significantly higher than that in patients without NI at each time point within 28 days of ECMO initiation. (Z = 5.816, P = 0.0159). Conclusion NI was a common complication in adult patients who received VA-ECMO after cardiac surgery, and time-dependent NI was an independent risk factor for predicting mortality in these patients. Using a competing risk model, we confirmed that NIs increased the risk of In-hospital mortality rate in these patients.

Abstract
Extra corporeal membrane oxygenation (ECMO) has become an important modality in ICU for treating patients with severe hemodynamic and respiratory failure. It helps clinicians gain time for the primary disease to recover with definitive treatment, and aids in cardio pulmonary recovery of the patient. Most of the patients who require ECMO support are quite sick and fragile. Nosocomial infection is second most common complication after hemorrhage in ECMO patients.It affects about two-third of patients receiving ECMO. There is a lack of sufficient knowledge in this particular area. More focused efforts should be made in future to combat nosocomial infection in ECMO patients.

Abstract
OBJECTIVES Extracorporeal membrane oxygenation (ECMO) is an extracorporeal life support strategy for the treatment of critically ill children with reversible heart and lung failure, increasingly being used in patients with low cardiac output after cardiac surgery. However, the mortality of patients is closely related to the complications of ECMO, especially bleeding, thrombosis, and infection, ECMO-related nosocomial infection has become a challenge to the success of ECMO. This study aims to analyze the incidence and risk factors for venoarterial-ECMO (VA-ECMO)-related nosocomial infections in children after cardiac surgery. METHODS We retrospectively collected the data of patients who underwent VA-ECMO treatment after pediatric cardiac surgery in the Second Xiangya Hospital of Central South University from July 2015 to March 2021, and divided them into an infected group and a non-infected group. The clinical characteristics of the 2 groups of patients, VA-ECMO-related nosocomial infection factors, pathogenic microorganisms, and patient mortality were compared. Logistic regression was used to analyze the risk factors for nosocomial infection related to VA-ECMO after cardiac surgery. RESULTS Of the 38 pediatric patients, 18 patients (47.37%) had VA-ECMO related nosocomial infection, served as the infected group, including 7 patients with blood infections and 11 respiratory tract infections. Gram-negative pathogens (16 strains, 88.9%) were the main bacteria, such as Acinetobacter baumannii (6 strains), Klebsiella pneumoniae (3 strains), and Stenotrophomonas maltophilia (3 strains). Compared with the non-infected group (n=20), the infection group had longer time of cardiopulmonary bypass, time of myocardial block, and time of VA-ECMO assistance (All P<0.05). Multivariate logistic regression analysis showed that time of cardiopulmonary bypass (OR=1.012, 95% CI 1.002 to 1.022; P=0.021) was an independent risk factor for ECMO-related nosocomial infection. The number of surviving discharges in the infected group was less than that in the non-infected group (1 vs 11, P<0.05). CONCLUSIONS Cardiopulmonary bypass time is an independent risk factor for VA-ECMO-related nosocomial infection in children after cardiac surgery. Shortening the duration of extracorporeal circulation may reduce the incidence of VA-EMCO-related nosocomial infections in children after cardic surgery. The occurrence of VA-ECMO-related nosocomial infections affects the number of patient's discharge alive.
