Nosocomial blood stream infections (BSIs) increase both the morbidity and the mortality of patients receiving extracorporeal life support (ECLS). The aim of this study was to identify common practices for blood stream infection prevention among national Extracorporeal Membrane Oxygenation (ECMO) programs. An electronic survey that comprised of a 16-item questionnaire was sent out to all ECMO program directors and coordinators within the United States that are part of the Extracorporeal Life Support Organization (ELSO) registry. A total of 152 institutions in 40 states were surveyed, with 85 (55%) responses. One-quarter of the institutions responded that an ECMO infection-prevention bundle or checklist was used during the cannulation. Less than half responded that an ECMO infection-prevention bundle or checklist was used for cannula maintenance, although a majority (82.9%) of institutions responded that a “standard approach to cannula dressings” was used. Half of the respondents reported antimicrobial prophylaxis was routinely prescribed for patients on ECMO, although specific regimens varied widely. Of the institutions, 34.2% reported sending daily blood cultures as part of routine surveillance. Smaller programs were more likely to send daily surveillance blood cultures (58.8%, P < .01). We found no clear consensus on practices used to prevent BSI in patients receiving ECMO.

The Impact

AbstractBackgroundMorbidity is defined as a state of being unhealthy or of experiencing an aspect of health that is “generally bad for you”, and postoperative morbidity linked to paediatric cardiac surgery encompasses a range of conditions that may impact the patient and are potential targets for quality assurance.MethodsAs part of a wider study, a multi-disciplinary group of professionals aimed to define a list of morbidities linked to paediatric cardiac surgery that was prioritised by a panel reflecting the views of both professionals from a range of disciplines and settings as well as parents and patients.ResultsWe present a set of definitions of morbidity for use in routine audit after paediatric cardiac surgery. These morbidities are ranked in priority order as acute neurological event, unplanned re-operation, feeding problems, the need for renal support, major adverse cardiac events or never events, extracorporeal life support, necrotising enterocolitis, surgical site of blood stream infection, and prolonged pleural effusion or chylothorax. It is recognised that more than one such morbidity may arise in the same patient and these are referred to as multiple morbidities, except in the case of extracorporeal life support, which is a stand-alone constellation of morbidity.ConclusionsIt is feasible to define a range of paediatric cardiac surgical morbidities for use in routine audit that reflects the priorities of both professionals and parents. The impact of these morbidities on the patient and family will be explored prospectively as part of a wider ongoing, multi-centre study.

The Impact

Abstract Background Coronavirus disease 19 (COVID-19) leading to acute respiratory distress syndrome is associated with need for intensive care (IC), mechanical ventilation (MV), and prolonged recovery. These patients are thus predisposed to blood stream infections which can worsen outcomes. This risk may be aggravated by adjunctive therapies. Methods We reviewed the medical records of all adults admitted to Stony Brook University Hospital, NY, from March 1 to April 15, 2020 with severe COVID-19 pneumonia (requiring high-flow O2). Patients who received MV or died within 24h were excluded. Patients were followed until death or hospital discharge. We reviewed positive blood cultures (PBC) for pathogenic microorganisms, and calculated the incidence of bacteremia, rates of infective endocarditis (IE), and impact on mortality. Microbes isolated only once and belonging to groups defined as commensal skin microbiota were labelled as contaminants. We also examined the impact of adjunctive therapies with immunosuppressive potential (steroids and tocilizumab), on bacteremia. Results A total of 469 patients with severe COVID-19 pneumonia were included (Table 1). Of these, 199 (42.4%) required IC and 172 (36.7%) MV. Median length of stay was 13 days (8–22) and 94 (20.0%) had PBC. Of these, 43 were considered true pathogens (bacteremia), with predominance of E. faecalis and S. epidermidis, and 51 were considered contaminants (Table 2). The incidence of bacteremia (43/469, 9.2%) was 5.1 per 1000 patient-days (95%CI 3.8–6.4). An echocardiogram was performed in 21 patients, 1 had an aortic valve vegetation (IE) by methicillin sensitive S. aureus. Bacteremia rates were nonsignificantly higher with steroids (5.9 vs 3.7 per 1000 patient-days; P=0.057). Use of tocilizumab was not associated with bacteremia (5.8 vs 4.8 per 1000 patient-days; P=0.28). Mortality was nonsignificantly higher in patients with (15/43, 34.9%) vs. without (108/426, 25.4%) bacteremia (P=0.20). Length of stay was the strongest predictor of bacteremia, with risk increasing by 7% (95%CI 6%-9%, P&lt; 0.001) per additional day. Cohort Characteristics of Patients with Severe COVID-19 Pneumonia on High-Flow O2 (N= 469) All Microorganisms Isolated from Blood Cultures Conclusion The incidence of bacteremia was relatively low and IE was uncommon in this study of severe COVID-19 patients. Risk of bacteremia increased with longer hospital stay and with steroids use, but not with tocilizumab. Disclosures All Authors: No reported disclosures

Technological Advances

Introduction: The use of extracorporeal membrane oxygenation (ECMO) is considered by many authors as one of the most important technological advances in the care of newborns with congenital diaphragmatic hernia. The main objective of this study was to report the experience of a Portuguese ECMO center in the treatment of congenital diaphragmatic hernia.Material and Methods: Descriptive retrospective study of newborns with congenital diaphragmatic hernia requiring ECMO support in a Pediatric Intensive Care Unit from January 2012 to December 2019. Data collection using the Extracorporeal Life Support Organization registration and unit data base.Results: Fourteen newborns were included, all with left congenital diaphragmatic hernia, in a total of 15 venoarterial ECMO cycles. The median gestational age was 38 weeks and the median birth weight was 2.950 kg. Surgical repair was performed before entry into ECMO in six, during in seven and after in one newborn. The average age at placement was 3.3 days and the median cycle duration was 16 days. Prior to ECMO, all newborns had severe hypoxemia and acidosis despite optimized ventilatory support, with nitric oxide and inotropic therapy. After 24 hours on ECMO, there was correction of acidosis, improvement of oxygenation and hemodynamic stability. All cycles presented mechanical complications, the most frequent being the presence of clots in the circuit. The most frequent physiological complications were hemorrhagic and embolic (three newborns suffered an ischemic stroke during the cycle). Five newborns (35.7%) died, all associated with complications (two strokes, two massive bleedings and one accidental decannulation). Chronic lung disease, poor weight gain and psychomotor developmental delay were the most frequent long-term morbidities.Discussion: Despite technological advances in respiratory care and improved safety of the ECMO technique, the management of these newborns is complex and there are still several open questions, including the appropriate selection of patients, the best approach and time for surgical correction, and the treatment of pulmonary hypertension in the presence of persistent fetal shunts.Conclusion: Survival rate was higher than reported in 2017 Extracorporeal Life Support Organization report (64% versus 50%). Mechanical and hemorrhagic complications were very frequent.
