ABSTRACT

Common marginal donor liver mainly consists of fatty donor liver, elderly donor liver, small volume donor liver and liver graft from donation after cardiac death (DCD), etc. The application of marginal donor liver may resolve the severe shortage of donor liver to certain extent. Nevertheless, marginal donor liver yields a higher risk of ischemia-reperfusion injury (IRI) and causes more severe IRI than normal donor liver, which is a main cause for the failure of transplantation. In addition, oxidative stress is a major risk factor causing IRI of marginal donor liver. Therefore, how to mitigate oxidative stress and alleviate IRI of marginal donor liver has become a hot spot in clinical practice. Reactive oxygen species (ROS)-mediated oxidative stress occurs throughout the whole process of IRI. In this article, the role of oxidative stress in IRI of marginal donor liver transplantation and the ROS-targeted prevention and treatment were reviewed, aiming to provide reference for clinical practice.

ABSTRACT

Objective To evaluate the feasibility and safety of tracheal extubation in operating room for patients with end-stage chronic obstructive pulmonary disease (COPD) after single-lung transplantation. Methods Clinical data of 57 recipients who underwent single-lung transplantation due to end-stage COPD were retrospectively analyzed. According to the evaluation indexes of tracheal extubation in operating room established by our hospital, 17 recipients eligible for tracheal extubation in operating room were assigned into the operating room extubation group (OR extubation group) and 40 recipients receiving tracheal extubation in intensive care unit (ICU) were allocated in the ICU extubation group. The evaluation results of intraoperative tracheal extubation and postoperative recovery were compared between two groups. Results Compared with the ICU extubation group, recipients in the OR extubation group had higher oxygenation index, lower arterial partial pressure of carbon dioxide (PaCO2), lower blood lactic acid level, less fluctuation range of blood pressure and fewer cases receiving extracorporeal membrane oxygenation (ECMO) during operation (all P < 0.05). Two recipients in the OR extubation group received repeated tracheal intubation at 6 and 8 h after returning to ICU, and tracheal extubation at postoperative 6 and 9 d. In the OR extubation group, time of postoperative mechanical ventilation, length of postoperative ICU and hospital stay of the recipients were shorter than those in the ICU extubation group (all P < 0.05). The incidence of grade 3 primary graft dysfunction (PGD), atrial tachyarrhythmia, continuous renal replacement therapy and 1-year survival rate did not significantly differ between two groups (all P > 0.05). Conclusions The tracheal extubation regimen in the operating room for COPD patients after single-lung transplantation established by our hospital is safe and feasible, which shortens the time of postoperative mechanical ventilation, the length of postoperative ICU and hospital stay, whereas does not increase the incidence of postoperative complications.

ABSTRACT

Organ donation after citizen's death has become the main source of organ donation in China. However, the complexity of donor quality and the increasing proportion of expanded criteria donor (ECD) exert significant impact upon the availability of donor kidney and the long-term prognosis of recipients after kidney transplantation. Strengthening the quality maintenance and evaluation of donor kidney is of great significance for improving the quality of donor kidney, increasing the procurement and utilization of donor kidney and prolonging the long-term survival of recipients and kidney allografts. As one of the major approaches of organ preservation, machine perfusion preservation may not only prolong the preservation time and improve the quality of donor kidney, but also play a critical role in the repair and function evaluation of donor kidney. Based on literature review, several hot issues, corresponding treatment strategies and research progress on machine perfusion in the quality maintenance of donor kidney from organ donation after citizen's death were reviewed in this article, aiming to provide reference for selecting the optimal preservation method of donor kidney and enhancing the quality and utilization rate of ECD donor kidney.

ABSTRACT

RESUMEN Introducción: La oxigenación por membrana extracorpórea venoarterial (ECMO VA) es una intervención de rescate en pacientes con shock cardiogénico (SC), y paro cardiorrespiratorio (PCR) refractarios a las terapias convencionales. Objetivo: Describir las características, y resumir nuestra experiencia inicial de 7 años de pacientes que requirieron ECMO VA por SC o PCR. Material y métodos: Se realizó un estudio de cohorte unicéntrico. Se analizaron retrospectivamente los pacientes adultos consecutivos que fueron asistidos con ECMO VA por SC o PCR refractarios entre 2014 y 2020 en el ICBA Instituto Cardiovascular. Resultados: Se incluyeron 54 pacientes, (54 ± 12 años). El 36,5% presentó miocardiopatía isquémica, y el 23,1% enfermedad valvular significativa. Las indicaciones para ECMO VA fueron: poscardiotomía (43,4%), SC refractario (28,3%), y falla primaria del injerto (20,8%). La reanimación cardiopulmonar previa a la ECMO VA se realizó en el 18,5%. La canulación fue periférica en el 81,5%, el 83,3% se asistió en INTERMACS 1, y el 87% presentaba balón de contrapulsación intraaórtico. La duración de asistencia en ECMO VA fue de 5,5 días (RIC 2,8-10). La tasa de supervivencia en ECMO VA fue del 63% (37% puente a trasplante cardíaco, y 26% recuperación), y al alta del 42,6%. Las complicaciones más frecuentes fueron: sangrado (61,1%), infección (51,9%), y complicaciones tromboembólicas (46,3%). Conclusión: La ECMO VA como tratamiento del SC o PCR refractarios en nuestro centro presentó una sobrevida aceptable al alta hospitalaria. La ECMO VA es un tratamiento efectivo cuando las terapias convencionales fallan, siendo aparentemente útil y aplicable en un país donde existe acceso limitado a los dispositivos de asistencia ventricular compleja.


ABSTRACT Background: Venoarterial extra corporeal membrane oxygenation (VA-ECMO) is a rescue intervention used in patients with cardiogenic shock (CS) or cardiac arrest (CA) refractory to conventional medical therapies. Objective: The aim of the present study is to describe the characteristics and summarize our 7-year experience in patients with CS or CA supported with VA-ECMO. Methods: We conducted a single-center retrospective study analyzing consecutive adult patients requiring VA-ECMO due to refractory CS or CA at ICBA, Instituto Cardiovascular between January 2014 and December 2020. Results: A total age 54 patients were included (54 ± 12 years), 36.5% presented ischemic cardiomyopathy and 23.1% significant valvular heart disease. The indications for VA-ECMO implantation were post-cardiotomy (43.4%), refractory CS (28.3%) and primary graft dysfunction (20.8%). Cardiopulmonary resuscitation before VA-ECMO occurred in 18.5% of the cases. Peripheral cannulation was performed in 81.5% of the cases, 83.3% had INTERMACS profile 1 and 87% were on intraaortic balloon pump. Duration of ventricular assistance on VA- ECMO was 5.5 days (IQR 2.8-10). Survival rate on ECMO VA was 63% (37% as a bridge to cardiac transplantation and 26% as a bridge to recovery) and survival to discharge was 42.6%. The most common complications were hemorrhage (61.1%), infections (51.9%), and thromboembolic complications (46.3%). Conclusion: In our center, VA-ECMO as a treatment for refractory CS or CA showed acceptable survival during ventricular support and on hospital discharge. It is an effective life support treatment to rescue critically ill patients when conventional therapies fail, is apparently useful and can be implemented in a country with limited resources and access to complex ventricular assist devices.

ABSTRACT

RESUMO Objetivo: Avaliar o impacto no número de casos de oxigenação por membrana extracorpórea e as taxas de sobrevivência nos anos seguintes à pandemia de H1N1 de 2009. Métodos: Avaliaram-se dois períodos distintos de utilização de oxigenação por membrana extracorpórea como suporte para insuficiência respiratória em crianças, por meio da análise de conjuntos de dados da Extracorporeal Life Support Organization. Foram construídos modelos autorregressivos integrados de médias móveis para estimar os efeitos da pandemia. O ano de 2009 foi o ano de intervenção (epidemia de H1N1) em um modelo de séries temporais interrompidas. Os dados colhidos entre 2001 e 2010 foram considerados pré-intervenção e os obtidos entre 2010 e 2017 como pós-intervenção. Resultados: Em comparação com o período entre 2001 e 2010, o período entre 2010 e 2017 mostrou aumento das taxas de sobrevivência (p < 0,0001), com melhora significante da sobrevivência quando se realizou oxigenação por membrana extracorpórea nos casos de insuficiência aguda por pneumonia viral. Antes do ponto de nível de efeito (2009), o modelo autorregressivo integrado de médias móveis mostrou aumento de 23 casos de oxigenação por membrana extracorpórea ao ano. Em termos de sobrevivência, a curva mostra que não houve aumento significante das taxas de sobrevivência antes de 2009 (p = 0,41), porém o nível de efeito foi próximo à significância após 2 anos (p = 0,05), com aumento de 6% na sobrevivência. Em 4 anos, ocorreu aumento de 8% (p = 0,03) na sobrevivência, e, 6 anos após 2009, a sobrevivência mostrou aumento de até 10% (p = 0,026). Conclusão: Nos anos após 2009, ocorreu significante e progressivo aumento global das taxas de sobrevivência com oxigenação por membrana extracorpórea para todos os casos, principalmente em razão de melhoras tecnológicas e dos protocolos de tratamento para insuficiência respiratória aguda relacionada à pneumonia viral e a outras condições respiratórias.


ABSTRACT Objective: To evaluate whether there was any impact on the number of pediatric extracorporeal membrane oxygenation runs and survival rates in the years subsequent to the 2009 pandemic. Methods: We studied two different periods of extracorporeal membrane oxygenation support for respiratory failure in children by analyzing datasets from the Extracorporeal Life Support Organization. Autoregressive integrated moving average models were constructed to estimate the effect of the pandemic. The year 2009 was the year of intervention (the H1N1 epidemic) in an interrupted time series model. Data collected from 2001 - 2010 were considered preintervention, and data collected from 2010 - 2017 were considered postintervention. Results: There was an increase in survival rates in the period 2010 - 2017 compared to 2001 - 2010 (p < 0.0001), with a significant improvement in survival when extracorporeal membrane oxygenation was performed for acute respiratory failure due to viral pneumonia. The autoregressive integrated moving average model shows an increase of 23 extracorporeal membrane oxygenation runs per year, prior to the point of the level effect (2009). In terms of survival, the preslope shows that there was no significant increase in survival rates before 2009 (p = 0.41), but the level effect was nearly significant after two years (p = 0.05), with a 6% increase in survival. In four years, there was an 8% (p = 0.03) increase in survival, and six years after 2009, there was up to a 10% (p = 0.026) increase in survival. Conclusion: In the years following 2009, there was a significant, global incremental increase in the extracorporeal membrane oxygenation survival rates for all runs, mainly due to improvements in the technology and treatment protocols for acute respiratory failure related to viral pneumonia and other respiratory conditions.

ABSTRACT

RESUMO Uma mulher com 63 anos de idade compareceu ao pronto-socorro com história aguda de febre, prostração e dispneia. Recebeu diagnóstico de quadro grave da COVID-19 e síndrome do desconforto respiratório agudo. Apesar de suporte clínico intensivo, cumpriu os critérios para ser submetida à oxigenação venovenosa por membrana extracorpórea. No dia 34, após 7 dias de desmame da sedação com evolução positiva de seu quadro neurológico, apresentou uma crise tônico-clônica generalizada limitada, não relacionada com desequilíbrio hidroeletrolítico ou metabólico, que levou à necessidade de investigação diagnóstica. Seus exames de imagem cerebral revelaram síndrome da encefalopatia posterior reversível. Este caso enfatiza a questão das complicações neurológicas em pacientes com COVID-19 grave e a importância do diagnóstico e suporte precoces.


ABSTRACT A 63-year-old woman presented to the emergency department with an acute history of fever, prostration and dyspnea. She was diagnosed with severe COVID-19 acute respiratory distress syndrome and, despite optimized critical care support, met the indications for veno-venous extracorporeal membrane oxygenation. On day 34, after 7 days of wean sedation with a positive evolution of neurologic status, she presented a limited generalized tonic-clonic seizure not related to hydroelectrolytic or metabolic imbalance, which led to a diagnostic investigation; her brain imaging tests showed a posterior reversible encephalopathy syndrome. This case emphasizes the issue of neurological complications in patients with severe COVID-19 infection and the importance of early diagnosis and support.

ABSTRACT

ABSTRACT CONTEXT: Heart failure in Brazil is a major public health problem and, even with advances in treatment, it still presents high morbidity and mortality. As a treatment option, mechanical circulatory assist devices (MCADs) have greatly increased in importance over the last decade. CASE REPORT: This report concerns a case of refractory cardiogenic shock due to acute myocarditis in a 35-year-old puerperal female patient who presented with retrosternal pain, fatigue and dyspnea. At the hospital, she was diagnosed with myocarditis. There was no improvement in perfusion even after receiving dobutamine, intra-aortic balloon passage (IAB) and venoarterial extracorporeal membrane oxygenation (VA-ECMO). Therefore, it was decided to implant a MCAD (CentriMag). During hospitalization, recovery from the bi-ventricular dysfunction was achieved. The CentriMag device was removed 10 days after it had been implanted, and the patient was discharged after another 8 days. The myocarditis was proven to be due to the Coxsackie virus. CONCLUSIONS: The decision to implant a MCAD should be individualized, as patient profiles do not always match the indications in the guidelines and protocols. In this study, clinical discussion of the case among the medical and multi-professional teams was essential in order to be able to successfully reverse the patient's severe clinical condition without sequelae, through using a CentriMag implant.

ABSTRACT

Abstract Introduction: The present study intends to systematically review the literature on the use of extracorporeal membrane oxygenation (ECMO) in patients with coronavirus disease 2019 (COVID-19). Methods: The research was carried out according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). Studies were selected from PubMed/MEDLINE and LILACS databases between December 2019 and May 17 2020, using the descriptors "ECMO AND COVID-19", "Extracorporeal Membrane Oxygenation AND COVID-19", "ECLS AND COVID-19", and "Extracorporeal Life Support AND COVID-19". Exclusion criteria were government epidemiological bulletins, comments, literature reviews, and articles without full access to content. Results: Two hundred and thirty-three scientific productions were found, however only 18 did not met the exclusion criteria and could be included in this study, amouting to a total of 911 patients - 624 (68.5%) men, 261 (28.6%) women, and 26 (2.8%) without sex information. The mean age of the patients was 53.7 years. ECMO was necessary in 274 (30.1%) people (200 [73%] submitted to veno-venous ECMO, nine [3.3%] to veno-arterial ECMO, and seven [2.5%] moved between these two types or needed a more specific ECMO according to the disease prognosis). Five studies did not specify the type of ECMO used, amounting 57 (20.8%) patients. Five patients (1.8%) were discharged, 77 (28.1%) died, 125 (45.6%) remained hospitalized until publication time of their respective studies, and 67 patients (24.4%) had no outcome information. Conclusion: It is evident that more research, covering larger populations, must be carried out in order to clearly elucidate the role of ECMO in the treatment of COVID-19.

ABSTRACT

Abstract Introduction: Extracorporeal membrane oxygenation (ECMO) is a life-saving treatment in cardiogenic and respiratory shock. It is prone to various complications, infection being among the most frequent. This study aims to define the prevalence and characteristics of infections in ECMO patients in a tertiary care center for cardiac diseases. Methods: All ECMO patients between 2012 and 2016 in a single cardiac center were retrospectively included. Demographic data, ECMO indications, type, site, duration, and infection-related data were recorded. Data were analyzed among all patients and separately between pediatric and adult patient groups. Results: One hundred and twenty-six patients, 66 (53.4%) pediatric and 60 (47.6%) adult, received ECMO within the study period. Mean age was 3.54±4.27 years in the pediatric group and 54.92±15.57 years in the adult group. The main indication for ECMO was postcardiotomy shock (77.8%). Forty-six (36.5%) of all cases developed a culture-proven nosocomial infection with a rate of 49/1000 ECMO days. Infection was associated with > 5 days of ECMO duration and hemodialysis requirement in all patients and lower age in the pediatric group. The most frequent infection site was the lower respiratory tract (14.3%), while the most common isolated organisms were Klebsiella (8.7%) and Streptococcus (4.8%) species. Conclusion: The respiratory tract is the most common site of infection, however, all sites impose a threat to recovery, with longer treatment durations required for patients with culture-proven infections. A better understanding of the infectious spectrum and its effect on the mortality and morbidity is required for more successful treatment of ECMO patients.

ABSTRACT

SUMMARY The extracorporeal membrane oxygenation (ECMO) is a procedure that has been used for a long time in reference centers worldwide. Its fundamental precept is to serve as a bridge to a definitive treatment in patients with severe, but potentially reversible, clinical conditions. Despite this, its use in cardiopulmonary arrest (ECPR) is still a matter of debate, especially when indicated in the emergency department. There is not yet a sufficient level of evidence to support its routine use. In Brasil, the procedure stopped being considered an experimental technique by the Federal Council of Medicine only in 2017. The objective of the present case is to share the pioneering spirit of a Brazilian reference center with ECPR in the emergency room and to discuss the future challenges of the ECMO technique.

ABSTRACT

@#Cardiogenic shock (CS) describes a physiological state of end-organ hypoperfusion characterized by reduced cardiac output in the presence of adequate intravascular volume. Mortality still remains exceptionally high. Veno-arterial extracorporeal membrane oxygenation (VA ECMO) has become the preferred device for short-term hemodynamic support in patients with CS. ECMO provides the highest cardiac output, complete cardiopulmonary support. In addition, the device has portable characteristics, more familiar to medical personnel. VA ECMO provides cardiopulmonary support for patients in profound CS as a bridge to myocardial recovery. This review provides an overview of VA ECMO in salvage of CS, emphasizing the indications, management and further direction.

ABSTRACT

Objective To analyze the early outcomes of heart transplantation in critical patients and its significance in donor allocation decision. Methods Clinical data of 449 recipients undergoing heart transplantation were retrospectively analyzed. According to preoperative status, all patients were divided into the critical status group (n=64) and general status group (n=385). The incidence of critical status was summarized. Clinical data of recipients were statistically compared between two groups. Postoperative survival and causes of death in recipients between two groups were analyzed. Perioperative results of critical recipients undergoing different mechanical circulation support as a bridge to heart transplantation were compared. Results Critical patients accounted for 14.3% of the total number of transplant recipients. The proportion of critical patients gradually increased in recent 5 years. Compared with the general status group, the recipients in critical status group had a lower proportion of smoking history, a higher proportion of cardiac surgery history, a higher serum level of creatinine, and a higher proportion of primary diseases of heart failure before heart transplantation(all P≤0.01). The proportion of undergoing mechanical circulation support was higher, the incidence of complications was higher, the stay time in intensive care unit (ICU) was longer and the in-hospital fatality was higher after heart transplantation in the critical status group (all P≤0.01). The 1-year survival rate of recipients in critical status group was significantly lower than that in general status group (83% vs. 95%, P < 0.01). The fatality of recipients due to infection and multiple organ failure in critical status group was higher than that in general status group. Among 64 critical recipients, 1 recipient received ventilator alone, and 63 recipients underwent mechanical circulation support devices as a bridge to heart transplantation. Among them, intra-aortic balloon pump (IABP) alone was applied in 49 cases (77%), 8 cases (13%) of extracorporeal membrane oxygenation (ECMO) combined with IABP, 4 cases (6%) of ECMO alone, and 2 cases (3%) of left ventricular assist device (LVAD) alone. Critical patients who received preoperative ECMO and ECMO combined with IABP bridging to heart transplantation have a higher proportion of postoperative complications, a longer ICU stay time, a longer mechanical ventilation time, and a higher proportion of hospital deaths. Conclusions The overall prognosis of critical patients undergoing heart transplantation is relatively poor. Effective preoperative management may reverse the high-risk status of critical patients in a certain extent. The limited quantity of donor heart should be allocated to the most urgent patients who can obtain the greatest benefit from heart transplantation.

ABSTRACT

With the increasing quantity of organ donors and the continual expansion of the definition of extended criteria donor (ECD) livers, the quality of donor liver has become a prominent issue affecting the high-quality development of liver transplantation, which is also the study focus in related fields. Resolving the shortage of organs to the maximal extent and promoting the high-quality development of organ transplantation lead the development direction of organ donation and transplantation in China. In recent years, the application of mechanical perfusion (MP) for the perfusion, preservation, evaluation and repair of donor liver has become a hot topic to improve the quality of liver transplantation within the international community. In this article, according to different conditions of the application of ECD livers in liver transplantation at home and abroad in combination with the research progress on MP in the international community and relevant research experience of our center, the feasibility of establishing an organ intensive care unit (ICU) with integrated organ protection techniques was discussed, aiming to promote the high-quality development of organ transplantation in China and further expand the technical connotation of the "Chinese model" of organ donation and transplantation.

ABSTRACT

Objective:To investigate the safety and the efficacy of percutaneous and surgical approach in femoro-femoral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) cannulation.Methods:All consecutive patients implanted with femoro-femoral VA-ECMO between January 2018 and December 2020 in Beijing Anzhen Hospital, Capital Medical University. Propensity score matching was used to compare outcomes of percutaneous and surgical groups while controlling for confounders.Results:Among the 276 patients who received femoro-femoral VA-ECMO (62 surgical and 214 percutaneous), propensity-score matching selected 52 pairs of patients with similar characteristics with mean age of(59.6±13.0)years old, in which 26 patients were female. There were a lower ECMO cannulation-associated complication (28.8% vs. 48.1%, P=0.044) and a lower hospital mortality (42.3% vs. 67.3%, P=0.010) in the percutaneous group. The circuit blood flow after ECMO initiation was similar in both groups[(3.3±0.8)L·min -1·kg -1 in percutaneous group vs. (3.2±0.7)L·min -1·kg -1 in surgical group, P=0.738]. The serum lactate was declined in both group after ECMO initiation[(5.4±5.8)mmol/L vs. (9.2±6.9)mmol/L, P<0.001 in percutaneous group; (6.3±6.2)mmol/L vs. (10.5±7.0)mmol/L, P=0.003 in surgical group]. Conclusion:Percutaneous approach is a safe and efficient technique in emoro-femoral VA-ECMO cannulation. Compared with surgical cannulation, percutaneous approach is associated with lower ECMO cannulation-associated complication and lower hospital mortality.

ABSTRACT

Objective:To evaluate perioperative coagulatory parameters and transfusion rates of lung transplantation recipients.Methods:Clinical data were retrospectively reviewed for 178 lung transplant recipients at China-Japan Friendship Hospital from March 2017 to July 2019. According to whether extracorporeal membrane oxygenation(ECMO)was used during perioperative period, they were divided into two groups of ECMO(131 cases)and without ECMO(47 cases). Clinical data, laboratory examinations and blood transfusion status of two groups were compared. In ECMO group, excluding secondary thoracotomy for hemostasis(7 cases)and incomplete data(2 cases), the remainders were divided into the groups of no red blood cell transfusion(63 cases), red blood cell transfusion(59 cases), plasma transfusion <1 000 ml(99 cases)and plasma transfusion≥1 000 ml (23 cases), no platelet transfusion(93 cases)and platelet transfusion(29 cases). Clinical data, laboratory examinations and ECMO-related parameters of recipients were analyzed by Bary Logistic regression.Results:Statistically significant inter-group differences existed in body mass index(BMI), disease course, primary disease, bilateral lung transplantation, laboratory examinations, postoperative blood transfusion volume, postoperative red blood cell and plasma transfusion ratio between groups with and without ECMO( P<0.05). Bilateral lung transplantation, ASA grade, differences in BMI, disease course, postoperative hemoglobin<100 g/L, postoperative PT/APTT/INR abnormalities and postoperative PLT count <100×10 9/L were independent risk factors for postoperative transfusion during ECMO. Conclusions:The application of ECMO during lung transplantation may affect the perioperative transfusion volume and demand.Fully assessing blood transfusion requirements, optimizing coagulation monitoring and identifying the independent influencing factors of postoperative blood transfusion facilitate clinical scientific and rational blood transfusions.
