Extracorporeal membrane oxygenation (ECMO) is a high-risk and low-volume life support with increasing clinical study. However, heterogenous outcome definitions impede data assimilation into evidence to guide practice. The Academic Research Consortium (ARC), an international collaborative forum committed to facilitating the creation of stakeholder-driven consensus nomenclature and outcomes for clinical trials of medical devices, supported the ECMO Core Elements Needed for Trials Regulation And quality of Life (ECMO-CENTRAL) ARC. The ECMO-CENTRAL ARC was assembled to develop definitions of paediatric ECMO adverse events for use in clinical trials and regulatory device evaluation. An initial candidate list of ECMO adverse events derived from the mechanical circulatory support ARC was supplemented with a review of ECMO-relevant adverse event definitions collated from literature published between Jan 1, 1988, and Feb 20, 2023. Distinct teams of international topic experts drafted separate adverse event definitions that were harmonised to existing literature when appropriate. Draft definitions were revised for paediatric ECMO relevance with input from patients, families, and an international expert panel of trialists, clinicians, statisticians, biomedical engineers, device developers, and regulatory agencies. ECMO-CENTRAL ARC was revised and disseminated across research societies and professional organisations. Up to three rounds of internet-based anonymous surveys were planned as a modified Delphi process. The expert panel defined 13 adverse event definitions: neurological, bleeding, device malfunction, acute kidney injury, haemolysis, infection, vascular access-associated injury, non-CNS thrombosis, hepatic dysfunction, right heart failure, left ventricular overload, lactic acidaemia, and hypoxaemia. Definitional structure varied. Among 165 expert panel members, 114 were eligible to vote and 111 voted. Consensus was achieved for all proposed definitions. Agreement ranged from 82% to 95%. ECMO-CENTRAL ARC paired rigorous development with methodical stakeholder involvement and dissemination to define paediatric ECMO adverse events. These definitions will facilitate new research and the assimilation of data across clinical trials and ECMO device evaluation in children., Competing Interests: Declaration of interests PMAA reports institution funding from the US Department of Defense (PRMRP clinical trial award #W81XWH2210301), National Institutes of Health (NIH R13HD104432), and the US Food and Drug Administration (FDA Grant Number U01FD004979/U01FD005978); and is the Treasurer for Extracorporeal Life Support Organization (ELSO).

Background: Trauma, including traumatic brain injury (TBI), is the leading cause of nonobstetric maternal mortality during pregnancy. Few data are available regarding the optimal management of pregnant patients with TBI, leading to a lack of dedicated guidelines. We performed an international survey to examine the management of severe TBI in pregnant patients, focusing on monitoring, therapy, and intensive care practices., Methods: This survey, endorsed by the World Society of Emergency Surgery, was composed of a questionnaire with 79 items divided into four sections: (1) general information (items 1-7), (2) management of the maternal-fetal unit (items 8-43), (3) management of intracranial hypertension (items 44-76), and (4) specific considerations (items 77-79)., Results: One hundred and twenty-two physicians from 110 centers in 35 countries responded. The main findings related to TBI care in pregnant patients included the following: (1) a lack of availability of a specific TBI protocol in pregnancy; (2) an increase in the utilization of magnetic resonance imaging as the primary neuroimaging tool; (3) higher hemoglobin thresholds for transfusion; and (4) a lower utilization of therapeutic hypothermia, neuromuscular blocking agents, and barbiturate coma. We also report large variability in the timing of cesarean section in pregnant patients with TBI (≥ 23 weeks of gestation) needing an emergency craniotomy (simultaneously 23% vs. later cesarean section 50.8%)., Conclusions: Great variability in the management of pregnant patients with severe TBI was identified worldwide from the results of our survey. These findings, highlighting the lack of robust evidence on this topic, will be helpful to stimulate future investigations and to promote educational efforts on this difficult scenario., (© 2024.

Background: Critical care of patients on extracorporeal membrane oxygenation (ECMO) with acute brain injury (ABI) is notable for a lack of high-quality clinical evidence. Here, we offer guidelines for neurological care (neurological monitoring and management) of adults during and after ECMO support., Methods: These guidelines are based on clinical practice consensus recommendations and scientific statements. We convened an international multidisciplinary consensus panel including 30 clinician-scientists with expertise in ECMO from all chapters of the Extracorporeal Life Support Organization (ELSO). We used a modified Delphi process with three rounds of voting and asked panelists to assess the recommendation levels., Results: We identified five key clinical areas needing guidance: (1) neurological monitoring, (2) post-cannulation early physiological targets and ABI, (3) neurological therapy including medical and surgical intervention, (4) neurological prognostication, and (5) neurological follow-up and outcomes. The consensus produced 30 statements and recommendations regarding key clinical areas. We identified several knowledge gaps to shape future research efforts., Conclusions: The impact of ABI on morbidity and mortality in ECMO patients is significant. Particularly, early detection and timely intervention are crucial for improving outcomes. These consensus recommendations and scientific statements serve to guide the neurological monitoring and prevention of ABI, and management strategy of ECMO-associated ABI., (© 2024. The Author(s).)

Purpose: Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is an integral part of the management algorithm of patients with severe respiratory failure refractory to evidence-based conventional treatments. Right ventricular injury (RVI) pertaining to abnormalities in the dimensions and/or function of the right ventricle (RV) in the context of VV-ECMO significantly influences mortality. However, in the absence of a universally accepted RVI definition and evidence-based guidance for the management of RVI in this very high-risk patient cohort, variations in clinical practice continue to exist., Methods: Following a systematic search of the literature, an international Steering Committee consisting of eight healthcare professionals involved in the management of patients receiving ECMO identified domains and knowledge gaps pertaining to RVI definition and management where the evidence is limited or ambiguous. Using a Delphi process, an international panel of 52 Experts developed Expert position statements in those areas. The process also conferred RV-centric overarching open questions for future research. Consensus was defined as achieved when 70% or more of the Experts agreed or disagreed on a Likert-scale statement or when 80% or more of the Experts agreed on a particular option in multiple-choice questions., Results: The Delphi process was conducted through four rounds and consensus was achieved on 31 (89%) of 35 statements from which 24 Expert position statements were derived. Expert position statements provided recommendations for RVI nomenclature in the setting of VV-ECMO, a multi-modal diagnostic approach to RVI, the timing and parameters of diagnostic echocardiography, and VV-ECMO settings during RVI assessment and management. Consensus was not reached on RV-protective driving pressure thresholds or the effect of prone positioning on patient-centric outcomes., Conclusion: The proposed definition of RVI in the context of VV-ECMO needs to be validated through a systematic aggregation of data across studies. Until further evidence emerges, the Expert position statements can guide informed decision-making in the management of these patients., (© 2024. Crown.)

Thoracoabdominal normothermic regional perfusion (TA-NRP) is increasingly implemented in donation after circulatory determination of death (DCD). Thoracoabdominal normothermic regional perfusion allows thoracic and abdominal organs to be perfused with warm, oxygenated blood after declaration of death, interrupting ischemia. Evidence is accumulating supporting the use of TA-NRP to improve the outcome of grafts from DCD donors. Thoracoabdominal normothermic regional perfusion may restore and maintain a near-physiological environment during procurement. Moreover, during TA-NRP it is feasible to evaluate the heart in situ. Thoracoabdominal normothermic regional perfusion could be performed through different cannulation techniques, central or peripheral, and, with different extracorporeal circuits. The use of conventional cardiopulmonary bypass and extracorporeal life support (ECLS) devices equipped with open circuits has been described. We report the use of a fully mobile, closed ECLS circuit to implement TA-NRP. The procedure was successfully performed in a peripheral center without a cardiac surgery program through a percutaneous cannulation approach. This strategy resulted in combined heart, liver, and kidney recovery despite a significantly prolonged functional warm ischemia time. The feasibility of TA-NRP using modified but still closed fully mobile ECLS circuits could furtherly support the expansion of DCD programs, increasing the availability of heart for transplantation, and the quality of the grafts, improving recipients' outcome., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © ASAIO 2024.)

Introduction: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) improves end-organ perfusion in cardiogenic shock but may increase afterload, which can limit cardiac recovery. Left ventricular (LV) unloading strategies may aid cardiac recovery and prevent complications of increased afterload. However, there is no consensus on when and which unloading strategy should be used., Methods: An online survey was distributed worldwide via the EuroELSO newsletter mailing list to describe contemporary international practice and evaluate heterogeneity in strategies for LV unloading., Results: Of 192 respondents from 43 countries, 53% routinely use mechanical LV unloading, to promote ventricular recovery and/or to prevent complications. Of those that do not routinely unload, 65% cited risk of complications as the reason. The most common indications for unplanned unloading were reduced arterial line pulsatility (68%), pulmonary edema (64%) and LV dilatation (50%). An intra-aortic balloon pump was the most frequently used device for unloading followed by percutaneous left ventricular assist devices. Echocardiography was the most frequently used method to monitor the response to unloading., Conclusions: Significant variation exists with respect to international practice of ventricular unloading. Further research is required that compares the efficacy of different unloading strategies and a randomized comparison of routine mechanical unloading versus unplanned unloading., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Dr Donker reports speaker fees from Getinge-Maquet and Fresenius-Xenios-NovaLung and research cooperation with Getinge-Maquet and FreseniusXenios-NovaLung.

Donation after circulatory death (DCD) programs are expanding in Europe, in the attempt to expand donors pool. Even in controlled DCD donors, however, a protracted warm ischemia time occurring in the perimortem period might damage organs, making these unsuitable for transplantation. Implementing a strategy of extracorporeal interval support for organ retrieval (EISOR), a regional reperfusion with normothermic, oxygenated blood provides a physiologic environment allowing extensive assessment of potential grafts, and potentially promotes recovery of native function. Here we report the results of a multi-center retrospective cohort study including 29 Maastricht Category III controlled DCD donors undergoing extracorporeal support in a regional DCD/EISOR Training Center, and in the network of referring In-Training Centers, under the liaison of the regional Transplant Coordination Center during COVID-19 pandemic, between March 2020 and November 2021. The study aims to understand whether a mobile, experienced EISOR team implementing a consistent technique and sharing its equipe, expertise and equipment in a regional network of hospitals, might be effective and efficient in implementing the regional DCD program activity even in a highly stressed healthcare system., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Programs of donation after cardiocirculatory determination of death (DCD) are increasingly established in many countries to increase the availability of organs for transplantation. The use of abdominal normothermic regional reperfusion (A-NRP), shortening total warm ischemia time (tWIT), has been recently recommended by the European Society for Organ Transplantation (ESOT) to decrease the risk potentially associated with transplantation of grafts from DCD donors. We aimed to describe our transesophageal ultrasound (TEU)-guided technique to implement A-NRP in controlled DCD (cDCD) donors through femorofemoral venoarterial extracorporeal support, preventing coronary and cerebral reperfusion occluding the aorta with a balloon. After assessment of the central vascular structures, the use of TEU in real time guides the insertion of the guidewires and the balloon. Moreover, TEU allows us to verify the proper positioning of a venous cannula and aortic balloon. The entire procedure may be performed without the need for fluoroscopic or radiographic evaluation, or limiting the need for fluoroscopic or radiology assistance to a selected scenario of difficult or expected difficult cannulation and/or balloon insertion. The distribution of interventions as antemortem and postmortem reflects the scenario imposed by Italian laws regulating organ procurement in DCD donors., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © ASAIO 2023.)

Background and Purpose: Extracorporeal membrane oxygenation (ECMO) continues to play an essential role in organ support in cardiogenic shock or acute respiratory distress syndrome and bridging to transplantation. The main purpose of the present survey was to define which clinical and organizational practices are adopted for the administration of physiotherapy in adult patients undergoing ECMO support worldwide., Methods: This international survey was conceived in November 2021. The survey launch was announced at the 10th EuroELSO (European ELSO chapter) Congress, London, May 2022., Results: The survey returned 32 questionnaires from 29 centers across 14 countries. 17 centers (53.1%) had more than 30 intensive care unit beds available and most (46.8%) were able to care for five to 10 patients on extracorporeal life support simultaneously. The predominant physiotherapist-to-patient ratio was 1:>5 (37.5%); physiotherapy was available 5/7 days and 7/7 days by 31.2% and 25% respectively. Respiratory physiotherapy was not defined by a specific protocol in most centers (46.8%) while 31.2% declared that the treatment commences less than 12 h after sedation is stopped/reduced. Mostly, early physiotherapy in non-cooperative ventilated patients was provided within the first 48 h (68.6%) and consisted of as passive range of motion, in-bed positioning, and splinting. Postural passages and sitting were provided to patients and walking was included in those advanced motor activities which are part of the treatment., Conclusion: Physiotherapy in patients on ECLS is feasible, however substantial variability exists between centers with a trend of delivering not protocolized and understaffed rehabilitation practices., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The use of extracorporeal membrane oxygenation (ECMO) has grown rapidly over the past decades because of evolving indications, advances in circuit technology, and encouraging results from modern trials. Because ECMO is a complex and highly invasive therapy that requires a multidisciplinary team, optimal education, training, and credentialing remain a challenge., Objective: The primary objectives of this study were to investigate the prevalence and application of ECMO education and ECMO practitioner credentialing at ECMO centers globally. In addition, we explored differences among education and credentialing practices in relation to various ECMO center characteristics., Methods: We conducted an observational study of ECMO centers worldwide using a survey querying participants in two major domains: ECMO education and ECMO practitioner credentialing. Of note, the questionnaire included ECMO program characteristics, such as type and size of hospital and ECMO experience and volume, to explore the association with the two domains., Results: A total of 241 (32%) of the 732 identified ECMO centers responded to the survey, representing 41 countries across the globe. ECMO education was offered at 221 (92%) of the 241 centers. ECMO education was offered at 105 (98.0%) high-ECMO volume centers compared with 136 (87.5%) low-ECMO volume centers ( P  = 0.005). Credentialing was established at 101 (42%) of the 241 centers. Credentialing processes existed at 52 (49.5%) high-ECMO volume centers compared with 51 (37.5%) low-ECMO volume centers ( P  = 0.08) and 101 (49.3%) Extracorporeal Life Support Organization centers compared with 1 (2.7%) non-Extracorporeal Life Support Organization center ( P  < 0.001)., Conclusion: We found significant variability in whether ECMO educational curricula are offered at ECMO centers. We also found fewer than half of the ECMO centers surveyed had established credentialing programs for ECMO practitioners. Future studies that assess variability in outcomes among centers with and without standardized educational and credentialing practices are needed., (Copyright © 2024 by the American Thoracic Society.)

The right ventricle (RV) is intricately linked in the clinical presentation of critical illness; however, the basis of this is not well-understood and has not been studied as extensively as the left ventricle. There has been an increased awareness of the need to understand how the RV is affected in different critical illness states. In addition, the increased use of point-of-care echocardiography in the critical care setting has allowed for earlier identification and monitoring of the RV in a patient who is critically ill. The first part of this review describes and characterizes the RV in different perioperative states. This second part of the review discusses and analyzes the complex pathophysiologic relationships between the RV and different critical care states. There is a lack of a universal RV injury definition because it represents a range of abnormal RV biomechanics and phenotypes. The term "RV injury" (RVI) has been used to describe a spectrum of presentations, which includes diastolic dysfunction (early injury), when the RV retains the ability to compensate, to RV failure (late or advanced injury). Understanding the mechanisms leading to functional 'uncoupling' between the RV and the pulmonary circulation may enable perioperative physicians, intensivists, and researchers to identify clinical phenotypes of RVI. This, consequently, may provide the opportunity to test RV-centric hypotheses and potentially individualize therapies., Competing Interests: Declaration of Competing Interest V.Z. is the chair and HY co-chair of the Protecting the Right Ventricle Network (PRORVNet), with B.S., S.D., J.S., K.V., A.S., and M.V.A. as members.

Donation after circulatory determination of death (DCD) is a valuable strategy to increase the availability of grafts for liver transplantation (LT). As the average age of populations rises, the donor pool is likely to be affected by a potential increase in DCD donor age in the near future. We conducted a prospective cohort study to evaluate post-transplantation outcomes in recipients of grafts from elderly DCD donors compared with younger DCD donors, and elderly donors after brainstem determination of death (DBD). From August 2020 to May 2022, consecutive recipients of deceased donor liver-only transplants were enrolled in the study. DCD recipients were propensity score matched 1:3 to DBD recipients. One-hundred fifty-seven patients were included, 26 of whom (16.6%) were transplanted with a DCD liver graft. After propensity score matching and stratification, three groups were obtained: 15 recipients of DCD donors ≥75 years, 11 recipients of DCD donors <75 years, and 28 recipients of DBD donors ≥75 years. Short-term outcomes, as well as 12 months graft survival rates (93.3%, 100%, and 89.3% respectively), were comparable among the groups. LT involving grafts retrieved from very elderly DCD donors was feasible and safe in an experienced high-volume center, with outcomes comparable to LTs from younger DCD donors and age-matched DBD donors., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Fallani, Stocco, Siniscalchi, Antonini, Stella, Amato, Prosperi, Turco, Morelli, Cescon and Ravaioli.)

Background: The high-quality evidence on managing COVID-19 patients requiring extracorporeal membrane oxygenation (ECMO) support is insufficient. Furthermore, there is little consensus on allocating ECMO resources when scarce. The paucity of evidence and the need for guidance on controversial topics required an international expert consensus statement to understand the role of ECMO in COVID-19 better. Twenty-two international ECMO experts worldwide work together to interpret the most recent findings of the evolving published research, statement formulation, and voting to achieve consensus., Objectives: To guide the next generation of ECMO practitioners during future pandemics on tackling controversial topics pertaining to using ECMO for patients with COVID-19-related severe ARDS., Methods: The scientific committee was assembled of five chairpersons with more than 5 years of ECMO experience and a critical care background. Their roles were modifying and restructuring the panel's questions and, assisting with statement formulation in addition to expert composition and literature review. Experts are identified based on their clinical experience with ECMO (minimum of 5 years) and previous academic activity on a global scale, with a focus on diversity in gender, geography, area of expertise, and level of seniority. We used the modified Delphi technique rounds and the nominal group technique (NGT) through three face-to-face meetings and the voting on the statement was conducted anonymously. The entire process was planned to be carried out in five phases: identifying the gap of knowledge, validation, statement formulation, voting, and drafting, respectively., Results: In phase I, the scientific committee obtained 52 questions on controversial topics in ECMO for COVID-19, further reviewed for duplication and redundancy in phase II, resulting in nine domains with 32 questions with a validation rate exceeding 75% (Fig. 1). In phase III, 25 questions were used to formulate 14 statements, and six questions achieved no consensus on the statements. In phase IV, two voting rounds resulted in 14 statements that reached a consensus are included in four domains which are: patient selection, ECMO clinical management, operational and logistics management, and ethics., Conclusion: Three years after the onset of COVID-19, our understanding of the role of ECMO has evolved. However, it is incomplete. Tota14 statements achieved consensus; included in four domains discussing patient selection, clinical ECMO management, operational and logistic ECMO management and ethics to guide next-generation ECMO providers during future pandemic situations., (© 2023.

Introduction : Simulation training offers an authentic team-based learning opportunity without risk to real patients. The Educational Corner at the annual congress of the European Branch of Extracorporeal Life Support Organisation (EuroELSO) provided an opportunity for multiple simulation training sessions facilitated by experts from all over the world. Aim : We aimed to review the educational impact of EuroELSO Educational Corner and whether it provides a quality ECLS training to a wide spectrum of multidisciplinary international attendees utilising high and low fidelity simulation, workshops and hands on sessions. Methods : During the congress, 43 sessions were conducted dedicated to ECLS education with identified educational objectives. The sessions focused on management of adults and children on V-V or V-A ECMO. Adult sessions covered emergencies on mechanical circulatory support with management of LVAD and Impella, managing refractory hypoxemia on V-V ECMO, emergencies on ECMO, renal replacement therapy on ECMO, V-V ECMO, ECPR cannulation and performing perfect simulation. Paediatric sessions covered ECPR neck and central cannulation, renal replacement on ECMO, troubleshooting, cannulation workshop, V-V recirculation, ECMO for single ventricle, PIMS-TS and CDH, ECMO transport and neurological injury. Results : The Educational Corner was attended by more than 400 participants over the two congress days. Majority of responders (88%) reported that training sessions met the set educational goals and objectives and that this would change their current practice. Almost all (94%) reported that they received useful information and 95% would recommend the session to their colleagues. Conclusion : The Educational Corner, as an integral component of the annual EuroELSO congress, achieved the set educational goals and provided quality education based on the recipient survey. Structured multidisciplinary ECLS education with standardised curriculum and feedback is an important key step in delivering quality training to an international audience. Standardisation of European ECLS education remains an important focus of the EuroELSO.

Combined advances in haematopoietic cell transplantation (HCT) and intensive care management have improved the survival of patients with haematological malignancies admitted to the intensive care unit. In cases of refractory respiratory failure or refractory cardiac failure, these advances have led to a renewed interest in advanced life support therapies, such as extracorporeal membrane oxygenation (ECMO), previously considered inappropriate for these patients due to their poor prognosis. Given the scarcity of evidence-based guidelines on the use of ECMO in patients receiving HCT and the need to provide equitable and sustainable access to ECMO, the European Society of Intensive Care Medicine, the Extracorporeal Life Support Organization, and the International ECMO Network aimed to develop an expert consensus statement on the use of ECMO in adult patients receiving HCT. A steering committee with expertise in ECMO and HCT searched the literature for relevant articles on ECMO, HCT, and immune effector cell therapy, and developed opinion statements through discussions following a Quaker-based consensus approach. An international panel of experts was convened to vote on these expert opinion statements following the Research and Development/University of California, Los Angeles Appropriateness Method. The Appraisal of Guidelines for Research and Evaluation statement was followed to prepare this Position Paper. 36 statements were drafted by the steering committee, 33 of which reached strong agreement after the first voting round. The remaining three statements were discussed by all members of the steering committee and expert panel, and rephrased before an additional round of voting. At the conclusion of the process, 33 statements received strong agreement and three weak agreement. This Position Paper could help to guide intensivists and haematologists during the difficult decision-making process regarding ECMO candidacy in adult patients receiving HCT. The statements could also serve as a basis for future research focused on ECMO selection criteria and bedside management., Competing Interests: Declaration of interests DB has received research support from and provided consultation to LivaNova; has been on the medical advisory boards for Abiomed, Xenios, Medtronic, Inspira, and Cellenkos; and is the president-elect of ELSO and the Chair of the Executive Committee of the International ECMO Network.

Introduction: Patients with poor-grade subarachnoid hemorrhage (SAH) admitted to the intensive care unit (ICU) often require prolonged invasive mechanical ventilation due to prolonged time to obtain neurological recovery. Impairment of consciousness and airway protective mechanisms usually require tracheostomy during the ICU stay to facilitate weaning from sedation, promote neurological assessment, and reduce mechanical ventilation (MV) duration and associated complications. Percutaneous dilatational tracheostomy (PDT) is the technique of choice for performing a tracheostomy. However, it could be associated with particular risks in neurocritical care patients, potentially increasing the risk of secondary brain damage., Methods: We conducted a single-center, prospective, observational study aimed to assess PDT-associated variations in main cerebral, hemodynamic, and respiratory variables, the occurrence of tracheostomy-related complications, and their relationship with outcomes in adult patients with SAH admitted to the ICU of a neurosurgery/neurocritical care hub center after aneurysm control through clipping or coiling and undergoing early PDT., Results: We observed a temporary increase in ICP during early PDT; this increase was statistically significant in patients presenting with higher therapy intensity level (TIL) at the time of the procedural. The episodes of intracranial hypertension were brief, and appeared mainly due to the activation of cerebral autoregulatory mechanisms in patients with impaired compensatory mechanisms and compliance., Discussion: The low number of observed complications might be related to our organizational strategy, all based on a dedicated "tracheo-team" implementing both PDT following a strictly defined protocol and accurate follow-up., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Bini, Russo, Antonini, Pirini, Brunelli, Zumbo, Pronti, Rasi and Agnoletti.)

Background: Trauma is a leading cause of death and disability. Patients with trauma undergoing invasive mechanical ventilation (IMV) are at risk for ventilator-associated events (VAEs) potentially associated with a longer duration of IMV and increased stay in the intensive care unit (ICU)., Methods: We conducted a retrospective cohort study aimed to evaluate the incidence of infection-related ventilator-associated complications (IVACs), possible ventilator-associated pneumonia (PVAP), and their characteristics among patients experiencing severe trauma that required ICU admission and IMV for at least four days. We also determined pathogens implicated in PVAP episodes and characterized the use of antimicrobial therapy., Results: In total, 88 adult patients were included in the main analysis. In this study, we observed that 29.5% of patients developed a respiratory infection during ICU stay. Among them, five patients (19.2%) suffered from respiratory infections due to multi-drug resistant bacteria. Patients who developed IVAC/PVAP presented lower total GCS (median value, 7; (IQR, 9) vs. 12.5, (IQR, 8); p = 0.068) than those who did not develop IVAC/PVAP., Conclusions: We observed that less than one-third of trauma patients fulfilling criteria for ventilator associated events developed a respiratory infection during the ICU stay.

The introduction of pathways to enrol deceased donors after cardio-circulatory confirmation of death (donation after circulatory death, DCD) is expanding in many countries to face the shortage of organs for transplantation. The implementation of normothermic regional reperfusion (NRP) with warm oxygenated blood is a strategy to manage in-situ the organs of DCD donors. This approach, an alternative to in-situ cold preservation, and followed by prompt retrieval and cold static storage and/or ex-vivo machine perfusion (EVMP), could be limited to abdominal organs (A-NRP) or extended to the thorax (thoraco-abdominal, TA-NRP. NRP is also referred to as extracorporeal interval support for organ retrieval (EISOR). The use of EISOR is increasing in Europe, even if variably regulated. A-NRP has been demonstrated to be effective in decreasing the risk associated with transplantation of abdominal organs from DCD donors, and was recommended by the European Society for Organ Transplantation (ESOT) in a recent consensus document. We aim to explain how we select the candidates for DCD, to describe our regionalized model for implementing EISOR provision, and to introduce the health care professionals involved in this complex process, with their strictly defined roles, responsibilities, and boundaries. Finally, we report the results of our program, recruiting cDCD donors over a large network of hospitals, all pertaining to a Local Health Authority (Azienda Unità Sanitaria Locale, AUSL) in Romagna, Italy., Competing Interests: Competing interestsThe authors declare no competing interests., (© The Author(s) 2023.)

Background: Few data on the management of acute phase of traumatic spinal cord injury (tSCI) in patients suffering polytrauma are available. As the therapeutic choices in the first hours may have a deep impact on outcome of tSCI patients, we conducted an international survey investigating this topic., Methods: The survey was composed of 29 items. The main endpoints of the survey were to examine: (1) the hemodynamic and respiratory management, (2) the coagulation management, (3) the timing of magnetic resonance imaging (MRI) and spinal surgery, (4) the use of corticosteroid therapy, (5) the role of intraspinal pressure (ISP)/spinal cord perfusion pressure (SCPP) monitoring and (6) the utilization of therapeutic hypothermia., Results: There were 171 respondents from 139 centers worldwide. A target mean arterial pressure (MAP) target of 80-90 mmHg was chosen in almost half of the cases [n = 84 (49.1%)]. A temporary reduction in the target MAP, for the time strictly necessary to achieve bleeding control in polytrauma, was accepted by most respondents [n = 100 (58.5%)]. Sixty-one respondents (35.7%) considered acceptable a hemoglobin (Hb) level of 7 g/dl in tSCI polytraumatized patients. An arterial partial pressure of oxygen (PaO 2 ) of 80-100 mmHg [n = 94 (55%)] and an arterial partial pressure of carbon dioxide (PaCO 2 ) of 35-40 mmHg [n = 130 (76%)] were chosen in most cases. A little more than half of respondents considered safe a platelet (PLT) count > 100.000/mm 3 [n = 99 (57.9%)] and prothrombin time (PT)/activated partial thromboplastin time (aPTT) < 1.5 times the normal control [n = 85 (49.7%)] in patients needing spinal surgery. MRI [n = 160 (93.6%)] and spinal surgery [n = 158 (92.4%)] should be performed after intracranial, hemodynamic, and respiratory stabilization by most respondents. Corticosteroids [n = 103 (60.2%)], ISP/SCPP monitoring [n = 148 (86.5%)], and therapeutic hypothermia [n = 137 (80%)] were not utilized by most respondents., Conclusions: Our survey has shown a great worldwide variability in clinical practices for acute phase management of tSCI patients with polytrauma. These findings can be helpful to define future research in order to optimize the care of patients suffering tSCI., (© 2022. The Author(s).)

Purpose: Extracorporeal membrane oxygenation (ECMO) use for severe coronavirus disease 2019 (COVID-19) patients has increased during the course of the pandemic. As uncertainty existed regarding patient's outcomes, early guidelines recommended against establishing new ECMO centers. We aimed to explore the epidemiology and outcomes of ECMO for COVID-19 related cardiopulmonary failure in five countries in the Middle East and India and to evaluate the results of ECMO in 5 new centers., Methods: This is a retrospective, multicenter international, observational study conducted in 19 ECMO centers in five countries in the Middle East and India from March 1, 2020, to September 30, 2020. We included patients with COVID-19 who received ECMO for refractory hypoxemia and severe respiratory acidosis with or without circulatory failure. Data collection included demographic data, ECMO-related specific data, pre-ECMO patient condition, 24 h post-ECMO initiation data, and outcome. The primary outcome was survival to home discharge. Secondary outcomes included mortality during ECMO, survival to decannulation, and outcomes stratified by center type., Results: Three hundred and seven COVID-19 patients received ECMO support during the study period, of whom 78 (25%) were treated in the new ECMO centers. The median age was 45 years (interquartile range IQR 37-52), and 81% were men. New center patients were younger, were less frequently male, had received higher PEEP, more frequently inotropes and prone positioning before ECMO and were less frequently retrieved from a peripheral center on ECMO. Survival to home discharge was 45%. In patients treated in new and established centers, survival was 55 and 41% (p = 0.03), respectively. Multivariable analysis retained only a SOFA score < 12 at ECMO initiation as associated with survival (odds ratio, OR 1.93 (95% CI 1.05-3.58), p = 0.034), but not treatment in a new center (OR 1.65 (95% CI 0.75-3.67))., Conclusions: During pandemics, ECMO may provide favorable outcomes in highly selected patients as resources allow. Newly formed ECMO centers with appropriate supervision of regional experts may have satisfactory results., (© 2021. Springer-Verlag GmbH Germany, part of Springer Nature.)

The use of social media as a tool for professional communication and education in healthcare has been increasing; pros and cons of such platforms were extensively debated in recent years with mixed results. During the COVID-19 pandemic, social media use has accelerated to the point of becoming a ubiquitous part of modern healthcare systems. As with any tool in healthcare, its risks and benefits need to be carefully considered. In this article, we review the use of social media in the current pandemic. Importantly, we will illustrate this using experiences from the perspective of large medical organisations and also identify the common pitfalls., (© The Intensive Care Society 2020.)

Disclaimer: This is an updated guideline from the Extracorporeal Life Support Organization (ELSO) for the role of extracorporeal membrane oxygenation (ECMO) for patients with severe cardiopulmonary failure due to coronavirus disease 2019 (COVID-19). The great majority of COVID-19 patients (>90%) requiring ECMO have been supported using venovenous (V-V) ECMO for acute respiratory distress syndrome (ARDS). While COVID-19 ECMO run duration may be longer than in non-COVID-19 ECMO patients, published mortality appears to be similar between the two groups. However, data collection is ongoing, and there is a signal that overall mortality may be increasing. Conventional selection criteria for COVID-19-related ECMO should be used; however, when resources become more constrained during a pandemic, more stringent contraindications should be implemented. Formation of regional ECMO referral networks may facilitate communication, resource sharing, expedited patient referral, and mobile ECMO retrieval. There are no data to suggest deviation from conventional ECMO device or patient management when applying ECMO for COVID-19 patients. Rarely, children may require ECMO support for COVID-19-related ARDS, myocarditis, or multisystem inflammatory syndrome in children (MIS-C); conventional selection criteria and management practices should be the standard. We strongly encourage participation in data submission to investigate the optimal use of ECMO for COVID-19., Competing Interests: Disclosure: Dr. Stead is a chief executive officer of the Extracorporeal Life Support Organization (ELSO).

Disclaimer: The Extracorporeal Life Support Organization (ELSO) Coronavirus Disease 2019 (COVID-19) Guidelines have been developed to assist existing extracorporeal membrane oxygenation (ECMO) centers to prepare and plan provision of ECMO during the ongoing pandemic. The recommendations have been put together by a team of interdisciplinary ECMO providers from around the world. Recommendations are based on available evidence, existing best practice guidelines, ethical principles, and expert opinion. This is a living document and will be regularly updated when new information becomes available. ELSO is not liable for the accuracy or completeness of the information in this document. These guidelines are not meant to replace sound clinical judgment or specialist consultation but rather to strengthen provision and clinical management of ECMO specifically, in the context of the COVID-19 pandemic.

ECMO (Extracorporeal Membrane Oxygenation) is an extracorporeal life support system in catastrophic lung failure, shock and cardiopulmonary resuscitation, in different age groups, with multiple physiologic features. When the candidate to be submitted is too unstable to be transported to a hospital with ECMO, cannulation before transfer allows stabilization and subsequent transport. The aim of this article is to review the current concepts of extracorporeal support, its indications, national and international experience, and its possible role in the SARS-Cov2 pandemic.

Objectives: The purpose of this position paper is two-fold: first, to describe the state of extracorporeal membrane oxygenation education worldwide, noting current limitations and challenges; and second, to put forth an educational agenda regarding opportunities for an international collaborative approach toward standardization., Design: Relevant medical literature was reviewed through literature search, and materials from national organizations were accessed through the Internet. Taskforce members generated a consensus statement using an iterative consensus process through teleconferences and electronic communication., Setting: In 2018, the Extracorporeal Life Support Organization convened the ECMOed Taskforce at two structured, face-to-face meetings of 40 healthcare practitioners and educators with expertise in caring for the extracorporeal membrane oxygenation patient and in extracorporeal membrane oxygenation education., Patients: None., Interventions: None., Measurements and Main Results: The ECMOed Taskforce identified seven educational domains that would benefit from international collaborative efforts. Of primary importance, the Taskforce outlined actionable items regarding 1) the creation of a standardized extracorporeal membrane oxygenation curriculum; 2) defining criteria for an extracorporeal membrane oxygenation course as a vehicle for delivering the curriculum; 3) outlining a mechanism for evaluating the quality of educational offerings; 4) utilizing validated assessment tools in the development of extracorporeal membrane oxygenation practitioner certification; and 5) promoting high-quality educational research to guide ongoing educational and competency assessment development., Conclusions: Significant variability and limitations in global extracorporeal membrane oxygenation education exist. In this position paper, we outline a road map for standardizing international extracorporeal membrane oxygenation education and practitioner certification. Ongoing high-quality educational research is needed to evaluate the impact of these initiatives.

Objective: To evaluate the cerebral and hemodynamic effects of low-dose intramuscular diclofenac sodium (DCFS) administered for fever control in patients with acute brain injury in the intensive care unit., Methods: Inclusion criteria for this prospective clinical study were age ≥18 years; the ability to monitor intra-arterial blood pressure, core body temperature, and intracranial pressure; the placement of an indwelling jugular venous catheter for intermittent jugular venous oxygen saturation measurements; and a core body temperature ≥37.5°C. Exclusion criteria were hypovolemia, administration of drugs with hemodynamic effects during the study period, administration of antipyretics within 6 hours before the start of the study, acute heart failure, cerebral vasospasm, pregnancy, renal and gastric diseases, and allergy to DCFS., Results: The study enrolled 30 patients with acute brain injury. Two We observed statistically significant decreases in core body temperature (P < 0.001), systolic blood pressure (P < 0.001), diastolic blood pressure (P < 0.001), mean arterial pressure (P < 0.001), heart rate (P < 0.001), and cerebral perfusion pressure (P < 0.001) 2 hours after DCFS administration with respect to baseline (T0). The dosage of noradrenaline (norepinephrine) in subjects receiving treatment at the start of the study increased significantly from 0.14 μg/kg/minute ± 0.1 to 0.20 μg/kg/minute ± 0.1 (P = 0.0395)., Conclusions: Low-dose intramuscular DCFS administration for fever control in patients with acute brain injury is effective but also exposes patients to potentially deleterious hypotensive episodes that must be diagnosed and treated expeditiously to prevent further damage to the injured brain., (Copyright © 2016 Elsevier Inc.

Background: The aim of this study was to evaluate the association between fever after the first days of ICU stay and neurological outcome after cardiac arrest (CA)., Methods: We retrospectively analyzed CA patients admitted to intensive care unit (ICU)., Inclusion Criteria: age ≥18 years, Glasgow Coma Scale score ≤8 at ICU admission and assessment of body core temperature (BCT) using bladder or intravascular probes., Exclusion Criteria: ICU length of stay (LOS) <3 days and pregnancy. The primary endpoint was neurological outcome assessed with Cerebral Performance Category (CPC) scale 6 months after CA., Results: One hundred thirty-two patients were analyzed. Fever was present in 105 (79.6%) patients. Variables associated with unfavorable outcome were (1) older age (p < 0.0025); (2) non-shockable cardiac rhythms (p < 0.0001); (3) higher Simplified Acute Physiology Score (SAPS) II (p < 0.0001); (4) pupillary abnormalities at ICU admission (p < 0.018); and (5) elevated degree of maximal BCT (Tmax) during ICU stay (p < 0.046). After multivariate analysis, Tmax maintained a significant relationship with neurological outcome. An increase of 1 °C in Tmax during ICU stay decreased the odds ratio for a favorable outcome by a factor of 31% (p < 0.001). Moreover, we discovered a significant interaction between the day of Tmax (t-Tmax) and Tmax (p = 0.004); the later Tmax occurs, the more deleterious effects are observed on outcome., Conclusions: Fever is frequent after CA, and Tmax in ICU is associated with worsened neurological outcome. This association becomes stronger as the timing of Tmax extends further from the CA.

Background: Fever occurs frequently in acute brain injury patients, and its occurrence is associated with poorer outcomes. Paracetamol, an antipyretic frequently employed in patients with cerebral damage, may cause hypotension. We evaluated the cerebral and hemodynamic effects of intravenous (IV) paracetamol for the control of fever in Neuro-Intensive Care Unit (NICU) patients., Methods: This is a prospective observational study in which we enrolled 32 NICU patients: Subarachnoid Hemorrhage (SAH, n = 18), Traumatic Brain Injury (TBI, n = 10), Intracerebral Hemorrhage (ICH, n = 2) and Acute Ischemic Stroke (AIS, n = 2)., Results: The administration of paracetamol resulted in a decrease of core body temperature (Tc) (p = 0,0001), mean arterial pressure (MAP) (p = 0,0006), cerebral perfusion pressure (CPP) (p = 0,0033), and jugular venous oxygen saturation (SjVO2) (p = 0.0193), and in an increase of arteriojugular venous differences of oxygen (AVDO2) (p = 0.0012). The proportion of patients who had an infusion of norepinephrine increased from 47 % to 75 % (p = 0.0039 McNemar Test). When intracranial pressure (ICP) at the start of paracetamol infusion (t-0) was compared with the measurement of ICP after 2 h, a significant correlation was observed (r = 0.669, p = 0.0002). This marked and significant correlation can be explained by the fact that for the higher levels of ICP assessed at t-0 (greater than 15 mmHg), we observed a marked reduction of ICP concomitant with the decrease of Tc. No problems related to norepinephrine administration and/or increase in dosage were observed., Conclusion: Paracetamol administration is effective but exposes patients to hypotensive episodes that must be recognized and treated expeditiously to prevent further damage to the injured brain.

Introduction: Discrepant data exist regarding the incidence and severity of clinical problems related to intra-hospital transport of brain-injured patients and no consensus exists whether modern-day intra-hospital transport represents a safe or potentially problematic environment for neurointensive care unit (NICU) patients., Methods: We examined the incidence of clinical complications and physiological derangements that occurred in 160 neurologically injured patients (90 males, 70 females, mean age 57 ± 17 years) who underwent intra-hospital transport (288 cases, 237 scheduled, 51 unscheduled) for computed tomography scans., Results: Our findings indicate that (1) at least one significant complication (predominantly hemodynamic) occurred in over one-third (36%) of all transports (p = n.s scheduled vs. unscheduled) necessitating the deployment of interventions designed to treat changes in arterial pressure (2) despite the presence of trained medical personnel and availability of specialized equipment, intra-cranial pressure was not adequately monitored during transports (especially in patients with intra-cranial hypertension prior to transport) (3) intra-hospital transfer was associated with minor but statistically significant clinical changes, including a reduction in arterial partial pressure of oxygen (Pa(O(2)))/inspired oxygen fraction (Fi(O(2))) (only in the scheduled transport population), decreased arterial lactate levels (scheduled transport population), lowered body temperature (scheduled transport population), and increased arterial partial pressure of carbon dioxide (Pa(CO(2))) (scheduled transport population)., Conclusions: Intra-hospital transport of brain-injured NICU patients may present some hazards even if performed by skilled personnel with specialized equipment. In Trauma Centers such as ours, an improvement in the frequency of neuromonitoring [intra-cranial pressure (ICP) and end-tidal CO2 (ET(CO(2)))] during transport is recommended.
