Extracorporeal Membrane Oxygenation Is a Team Sport: Institutional Survival Benefits of a Formalized ECMO Team

Assessment of echocardiographic interpretation of dual-lumen cannula during venovenous extracorporeal membrane oxygenation use for pediatric respiratory failure

PURPOSE

Echocardiography is considered essential during cannulation placement and manipulations. Literature evaluating transthoracic echocardiography (TTE) usage during pediatric VV-ECMO is scant. The purpose of this study is to describe the use of echocardiography during VV-ECMO at a large, quaternary children's hospital.

METHODS

A retrospective, single-year cohort study was performed of pediatric patients on VV-ECMO via dual-lumen cannula at our institution from January 2019 through December 2019. For each echocardiogram, final cannula component (re-infusion port (ReP), distal tip, proximal port and distal port) positions were evaluated by one echocardiographer. For TTEs with ReP in the right atrium, two echocardiographers independently evaluated ReP direction using 2-point (Yes/No) and 4-point scales, which were semi-quantitative protocols using color Doppler images to estimate ReP jet direction to the tricuspid valve. Cohen's kappa or weighted kappa was used to measure interrater agreement.

RESULTS

During study period, 11 patients (64% male) received VV-ECMO with 49 TTEs and one transesophageal echocardiogram performed. The median patient age was 4.3 years [IQR: 1.1-11.5] and median VV-ECMO run time of 192 h [90-349]. The median time between TTEs on VV-ECMO was 34 h [8.3-65]. Most common position for the ReP was the right atrium (n = 33, 67%), and ReP location was not identified in five TTEs (10%). For ReP flow direction, echocardiographers agreed on 82% of TTEs using 2-point evaluation. There was only moderate agreement between echocardiographers on the 2-point and 4-point assessments (k = .54, kw = .46 respectively).

CONCLUSIONS

TTE is the predominant cardiac ultrasound modality used during VV-ECMO for pediatric respiratory failure. Subjective evaluation of VV-ECMO ReP jet direction in the right atrium is challenging, regardless of assessment method.

Changes in Therapy and Outcome of Patients Requiring Veno-Venous Extracorporeal Membrane Oxygenation for COVID-19

BACKGROUND

 Coronavirus disease 2019 (COVID-19)-related acute respiratory distress syndrome requiring veno-venous extracorporeal membrane oxygenation (vv-ECMO) is related with poor outcome, especially in Germany. We aimed to analyze whether changes in vv-ECMO therapy during the pandemic were observed and lead to changes in the outcome of vv-ECMO patients.

METHODS

 All patients undergoing vv-ECMO support for COVID-19 between 2020 and 2021 in a single center (n = 75) were retrospectively analyzed. Weaning from vv-ECMO and in-hospital mortality were defined as primary and peri-interventional adverse events as secondary endpoints of the study.

RESULTS

 During the study period, four infective waves were observed in Germany. Patients were assigned correspondingly to four study groups: ECMO implantation between March 2020 and September 2020: first wave (n = 11); October 2020 to February 2021: second wave (n = 23); March 2021 to July 2021: third wave (n = 25); and August 2021 to December 2021: fourth wave (n = 20). Preferred cannulation technique changed within the second wave from femoro-femoral to femoro-jugular access (p < 0.01) and awake ECMO was implemented. Mean ECMO run time increased by more than 300% from 10.9 ± 9.6 (first wave) to 44.9 ± 47.0 days (fourth wave). Weaning of patients was achieved in less than 20% in the first wave but increased to approximately 40% since the second one. Furthermore, we observed a continuous numerically decrease of in-hospital mortality from 81.8 to 57.9% (p = 0.61).

CONCLUSION

 Preference for femoro-jugular cannulation and awake ECMO combined with preexisting expertise and patient selection are considered to be associated with increased duration of ECMO support and numerically improved ECMO weaning and in-hospital mortality.

Integration of Extracorporeal Membrane Oxygenation into the Management of High-Risk Pulmonary Embolism: An Overview of Current Evidence

High-risk pulmonary embolism (PE) refers to a large embolic burden causing right ventricular failure and hemodynamic instability. It accounts for approximately 5% of all cases of PE but contributes significantly to overall PE mortality. Systemic thrombolysis is the first-line revascularization therapy in high-risk PE. Surgical embolectomy or catheter-directed therapy is recommended in patients with an absolute contraindication to systemic thrombolysis. Extracorporeal membrane oxygenation (ECMO) provides respiratory and hemodynamic support for the most critically ill PE patients with refractory cardiogenic shock or cardiac arrest. The complex management of these individuals requires urgent yet coordinated multidisciplinary care. In light of existing evidence regarding the utility of ECMO in the management of high-risk PE patients, a number of possible indications for ECMO utilization have been suggested in the literature. Specifically, in patients with refractory cardiac arrest, resuscitated cardiac arrest, or refractory shock, including in cases of failed thrombolysis, venoarterial ECMO (VA-ECMO) should be considered, either as a bridge to percutaneous or surgical embolectomy or as a bridge to recovery after surgical embolectomy. We review here the current evidence on the use of ECMO as part of the management strategy for the highest-risk presentations of PE and summarize the latest data in this indication.

Cardiac Extracorporeal Membrane Oxygenation in Community Cardiac Surgery Program: Are the Results Comparable?

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) outcomes in small centers are commonly considered less favorable than in large-volume centers. New ECMO protocols and procedures were established in our regional community hospital system as part of a cardiogenic shock initiative. This retrospective study aims to evaluate the outcomes of veno-arterial extracorporeal membrane oxygenation (VA ECMO) and extracorporeal cardiopulmonary resuscitation (ECPR) in a community hospital system with cardiac surgery capability and assess whether protocol optimization and cannulation standards result in comparable outcomes to larger centers whether the outcomes of this new ECMO program at the community hospital setting were comparable to the United States averages.

METHODS

Our regional system comprises five hospitals with 1500 beds covering southwestern New Jersey, with only one of these hospitals having cardiac surgery and ECMO capability. In May 2021, the new ECMO program was initiated. Patients were screened by a multidisciplinary call, cannulated by our ECMO team, and subsequently treated by the designated team. We reviewed our cardiac ECMO outcomes over two years, from May 2021 to April 2023, in patients who required ECMO due to cardiogenic shock or as a part of extracorporeal cardiopulmonary resuscitation (ECPR).

RESULTS

A total of 60 patients underwent cardiac ECMO, and all were VA ECMO, including 18 (30%) patients who required ECPR for cardiac arrest. The overall survival rate for our cardiac ECMO program turned out to be 48% (29/60), with 50% (22/42) in VA ECMO excluding ECPR and 39% (7/18) in the ECPR group. The hospital survival rate for the VA ECMO and ECPR groups was 36% (15/42) and 28% (5/18), respectively. The ELSO-reported national average for hospital survival is 48% for VA ECMO and 30% for ECPR. Considering these benchmarks, the hospital survival rate of our program did not significantly lag behind the national average.

CONCLUSIONS

With protocol, cannulation standards, and ECMO management optimized, the VA ECMO results of a community hospital system with cardiac surgery capability were not inferior to those of larger centers.

Implementing an Adult Extracorporeal Membrane Oxygenation Program During the COVID-19 Pandemic

BACKGROUND

In response to the needs of patients infected with COVID-19, an interdisciplinary team was assembled to implement an adult extracorporeal membrane oxygenation (ECMO) program in the surgical ICU of a West Texas tertiary care hospital. Use of Extracorporeal Life Support Organization (ELSO) guidelines was essential to the development of this effort.

AIM

The aim of this project was to develop, implement, and evaluate an adult ECMO program.

METHODS

A logic model was used in designing and evaluating the adult ECMO program. A 35-hour ECMO specialist training course was developed, and training began in August 2020, a month before implementation of the project began. Patient outcomes were measured between September 2020 and December 2021. Descriptive statistics were used to measure the clinical outcomes of interest.

RESULTS

Seventeen newly trained ECMO specialists included experienced critical care nurses and respiratory therapists. Protocols were developed for the initiation of ECMO, and tracked patient outcomes included survival off ECMO, survival to discharge, major and minor complications, and length of stay. Nine patients had COVID-19 and demonstrated an 11.11% mortality rate after adult ECMO program implementation.

CONCLUSIONS

Use of the ELSO professional guidelines to design and develop this project led to the achievement of a sustainable ECMO program. Hospital leaders can now implement adult ECMO programs amid other demands for resources that may be created by future pandemics.

[Impact of a multidisciplinary team "ECMO Team" on the prognosis of patients undergoing veno-arterial extracorporeal membrane oxygenation for refractory cardiogenic shock and cardiac arrest]

Objectives

Veno-arterial Extracorporeal membrane oxygenation (VA ECMO) is a salvage intervention in patients with cardiogenic shock (CS), and cardiac arrest (CA) refractory to standard therapies. The design of ECMO Teams has achieved the standardization of processes, although its impact on survival and prognosis is unknown.

Objective

We aimed to analyze whether the creation of an ECMO Team has modified the prognosis of patients undergoing VA ECMO for refractory CS or CA.

Materials and methods

. We conducted a single-center retrospective cohort study. Patients with refractory CS or CA who underwent VA ECMO were divided in two consecutive periods: from 2014 to April 2019 (pre-ECMO T) and from May 2019 to December 2022 (Post ECMO T). The main outcomes were survival on ECMO, in-hospital survival, complications, and annual ECMO volume.

Results

Eighty-three patients were included (36 pre-ECMO T and 47 post-ECMO T). The mean age was 53 +/-13 years. The most common reason for device indication was different: postcardiotomy shock (47.2%) pre-ECMO T and refractory cardiogenic shock (29.7%) post-ECMO T. The rate of extracorporeal cardiopulmonary resuscitation was 14.5%. The median duration of VA ECMO was longer after ECMO team implementation: 8 days (IQR 5-12.5) vs. five days (IQR 2-9, p=0.04). Global in-hospital survival was 45.8% (38.9% pre-ECMO T vs. 51.1% post-ECMO T; p=0.37), and the survival rate from VA ECMO was 60.2% (55.6% pre-ECMO T vs 63.8% post-ECMO T; p= 0.50). The volume of VA ECMO implantation was significantly higher in the post-ECMO team period (13.2 +/3.5 per year vs. 6.5 +/-3.5 per year, p: 0.02). The rate of complications was similar in both groups.

Conclusions

After the implementation of an ECMO team, there was no statistical difference in the survival rate of patients treated with VA ECMO. However, a significant increase in the number of patients supported per year was observed after the implementation of this multidisciplinary team. Post-ECMO T, the most common reason for device indication was cardiogenic shock, with longer run times and a higher rate of extracorporeal cardiopulmonary resuscitation.

Penetrating thoracic injury requiring emergency pneumonectomy supported with two ECMO runs: A testament to multidisciplinary critical care medicine

Post-traumatic pneumonectomies are uncommon and, if necessary, carry significant mortality. The use of extracorporeal membrane oxygenation (ECMO) for lung injury in trauma patient has demonstrated efficacy with minimal bleeding complications. We report a case of a young man with a penetrating thoracic injury that required a pneumonectomy supported with two separate ECMO runs for pulmonary failure postoperatively.

Key Considerations in Establishing a Pediatric Rescue Extracorporeal Life Support Program: A Multi Methods Review

Extracorporeal life support (ECLS) is generally limited to centers with cardiac surgery. However, pediatric centers without cardiac surgery can still provide potentially lifesaving ECLS through a Rescue Program, allowing a local team to cannulate and stabilize patients before they are transported to a center with cardiac surgery support for ongoing care. This multimethod study provides an exploration of pediatric ECLS team insights regarding program implementation and offers recommendations for other centers wishing to develop a similar program. We performed surveys and semi-structured interviews to gather perspectives from ECLS team members. Demographics and preliminary perspectives were obtained from surveys. Interviews were transcribed and coded using thematic analysis to identify key considerations, facilitators, and barriers related to rescue program implementation. Our multidisciplinary ECLS team perceived great value in the rescue program and identified elements critical to successful program development and implementation, including barriers that might exist for any center wishing to set up a similar program. Participants emphasized that the initial design and continued maintenance of any Rescue ECLS Program be a comprehensive, multidisciplinary initiative. Clear communication, a mechanism for debriefing and feedback, and a strategy allowing for flexible program evolution are essential.

Setting up a Rescue Extracorporeal Life Support Program

Extracorporeal life support (ECLS) is a high-risk, lifesaving medical treatment that is typically limited to centers that can support a comprehensive ECLS program. Rescue programs can bridge the gap in care between ECLS centers and other tertiary pediatric centers without cardiac surgical and comprehensive ECLS support. We describe how our pediatric center without cardiac surgery successfully partnered with an established ECLS center to develop a Rescue ECLS Cannulation Program. This formalized program provides cannulation and stabilization by a specialized team at the presenting hospital before being transported to a partner hospital. This article outlines how we established our unique Rescue ECLS Cannulation program. We outline the planning, development, and implementation of the program and describe the unique aspects contributing to successful implementation including longitudinal training, staged program evolution, and a bundled approach to care. We also describe the patients who we have cannulated since its inception. Rescue ECLS Cannulation Programs provide access to consistent, high-quality, and lifesaving care to critically ill patients at sites without the resources to support a full ECLS program.

Trends, Advantages and Disadvantages in Combined Extracorporeal Lung and Kidney Support From a Technical Point of View

Extracorporeal membrane oxygenation (ECMO) provides pulmonary and/or cardiac support for critically ill patients. Due to their diseases, they are at high risk of developing acute kidney injury. In that case, continuous renal replacement therapy (CRRT) is applied to provide renal support and fluid management. The ECMO and CRRT circuits can be combined by an integrated or parallel approach. So far, all methods used for combined extracorporeal lung and kidney support present serious drawbacks. This includes not only high risks of circuit related complications such as bleeding, thrombus formation, and hemolysis, but also increase in technical workload and health care costs. In this sense, the development of a novel optimized artificial lung device with integrated renal support could offer important treatment benefits. Therefore, we conducted a review to provide technical background on existing techniques for extracorporeal lung and kidney support and give insight on important aspects to be addressed in the development of this novel highly integrated artificial lung device.

The shock team: a multidisciplinary approach to early patient phenotyping and appropriate care escalation in cardiogenic shock

PURPOSE OF REVIEW

Cardiogenic shock (CS) is a highly morbid condition with mortality remaining greater than 30% despite improved pathophysiologic understanding and access to mechanical circulatory support (MCS). In response, shock teams modeled on successful multidisciplinary care structures for other diseases are being implemented nationwide.

RECENT FINDINGS

Primary data supporting a benefit of shock team implementation on patient outcomes are relatively limited and entirely observational. Four single-center before-and-after studies and one multicenter registry study have demonstrated improved outcomes in patients with CS, potentially driven by increased pulmonary artery catheter (PAC) utilization and earlier (and more appropriate) initiation of MCS. Shock teams are also supported by a growing body of literature recognizing the independent benefit of the interventions they seek to implement, including patient phenotyping with PAC use and an algorithmic approach to CS care. Though debated, MCS is also highly likely to improve CS outcomes when applied appropriately, which further supports a multidisciplinary shock team approach to patient and device selection.

SUMMARY

Shock teams likely improve patient outcomes by facilitating early patient phenotyping and appropriate intervention. Institutions should strongly consider adopting a multidisciplinary shock team approach to CS care, though additional data supporting these interventions are needed.

The Role of Extracorporeal Membrane Oxygenation in COVID-19

An extracorporeal membrane oxygenation (ECMO) program is an important component in the management of patients with COVID-19, but it is imperative to implement a system that is well-supported by the institution and staffed with well-trained clinicians to both optimize patient outcomes and to keep providers safe. There are many unknowns related to COVID-19, and one of the most challenging aspects for clinicians is the lack of predictive knowledge as to why some patients fail medical therapy and require advanced support such as ECMO. These factors can create challenges during a time of resource scarcity and interruptions in the supply chain. In the current environment, in which resources are limited and an ongoing pandemic, healthcare practitioners need to focus on evidence-based best practice for supportive care of patients with COVID-19 in refractory respiratory or cardiac failure. with As experience is gained, a greater understanding will develop in this cohort of patients regarding need and timing of ECMO. As this pandemic continues, it will be important to compile and analyze multicentered data pertaining to patient-specific outcomes to help guide clinicians caring for patients with COVID-19 undergoing ECMO support. In this paper, the authors demonstrate the strategies utilized by a major quaternary care center in the utilization and management of ECMO for patients with COVID-19.

Development of a Comprehensive Extracorporeal Membrane Oxygenation Program in a Cardiac Transplant Intensive Care Unit: A Quality Improvement Initiative

BACKGROUND

A major academic medical center in the Midwest has expanded their extracorporeal membrane oxygenation (ECMO) program from 8 ECMO cases in 2014 to 97 ECMO cases in 2017. The Extracorporeal Life Support Organization states that standardized policies, procedures, and standards of care are necessary for an ECMO center to be successful.

LOCAL PROBLEM

With the rapid growth of the ECMO program, this medical center has chosen to transition nurses and respiratory therapists into the role of ECMO specialist to bridge the gap in care created by the influx in patients. Currently, no specific set of policies/procedures or standards of care exist for ECMO patients. The primary objective of this study is to improve the self-efficacy of ECMO specialists and bedside nurses through the development of a comprehensive ECMO program that includes standardized policies and procedures, order sets, and evidence-based patient management guidelines.

METHODS/IMPLEMENTATION

The General Self-Efficacy Survey was used to assess the self-efficacy of both the ECMO specialists and the bedside nurses before implementation of the program. An ECMO manual was created that contained education on veno-arterial and veno-venous ECMO, policies and procedures, and patient management guidelines. An EPIC order set was created to ensure the correct protocols and management guidelines were ordered for all ECMO patients. Postimplementation self-efficacy surveys, direct observations, and chart audits occurred to assess program fidelity.

RESULTS

The self-efficacy was assessed of the ECMO specialists and beside nurses 4 months after implementation of policies, procedures, patient management guidelines, and an ECMO order set. The ECMO specialists' self-efficacy survey responses increased by 25% and the bedside nurses' self-efficacy survey responses increased by 27% after 4 months. Direct observation of ECMO specialist handoff to ensure protocol fidelity also occurred. There was a 40% increase in ECMO specialist handoff taking place and a 72% increase in ECMO circuit examination.

CONCLUSIONS

With the significant growth of ECMO patients, policies, protocols, and management guidelines are essential to provide safe care to these patients. There was a statistically significant improvement in the self-efficacy of both the ECMO specialists and bedside nurses. This was shown to directly correlate to an improvement in professional practice behaviors and ultimately improve the quality of patient care provided to ECMO patients.

Pediatric Extracorporeal Life Support Transport in Western Canada: Experience over 14 years

This retrospective cohort study describes all children transported on extracorporeal life support (ECLS) by the Stollery Children's Hospital Pediatric Transport team (SCH-PTT) between 2004 and 2018. We compared outcomes and complications between primary (SCH-PTT performed ECLS cannulation) vs. secondary (cannulation performed by referring facility) transports, as well as secondary transports from referring centers with and without an established ECLS cannulation program. SCH-PTT performed 68 ECLS transports during the study period. Median (IQR) transport distance was 298 (298-1,068) kilometers. Mean (SD) times from referral call to ECLS-initiation were: primary transports 7.8 (2.9) vs. 2.5(3.5) hours for secondary transports, p value < 0.001. Complications were common (n = 65, 95%) but solved without leading to adverse outcomes. There were no significant differences in the number of complications between primary and secondary transports. There was no significant difference in survival to ECLS decannulation between primary 9 (90%) and secondary transports 43 (74%), p value = 0.275. ECLS survival was higher for children cannulated by the SCH-PTT or a center with an ECLS cannulation program: 42 (82%) vs. 10 (59%), p value = 0.048. Critically ill children on ECLS can be safely transported by a specialized pediatric ECLS transport team. Secondary transports from a center with an ECLS cannulation program are also safe and have similar results as primary transports.

Human factors in ECLS - A keystone for safety and quality - A narrative review for ECLS providers

INTRODUCTION

Although the technology used for extracorporeal life support (ECLS) has improved greatly in recent years, the application of these devices to the patient is quite complex and requires extensive training of team members both individually and together. Human factors is an area that addresses the activities, contexts, environments, and tools which interact with human behavior in determining overall system performance.

HYPOTHESIS

Analyses of the cognitive behavior of ECLS teams and individual members of these teams with respect to the occurrence of human errors may identify additional opportunities to enhance safety in delivery of ECLS.

RESULTS

The aim of this article is to support health-care practitioners who perform ECLS, or who are starting an ECLS program, by establishing standards for the safe and efficient use of ECLS with a focus on human factor issues. Other key concepts include the importance of ECLS team leadership and management, as well as controlling the environment and the system to optimize patient care.

CONCLUSION

Expertise from other industries is extrapolated to improve patient safety through the application of simulation training to reduce error propagation and improve outcomes.

Short-term and intermediate outcomes of cardiogenic shock and cardiac arrest patients supported by venoarterial extracorporeal membrane oxygenation

Background

Cardiogenic shock and cardiac arrest are life-threatening emergencies with high mortality rates. Veno-arterial extracorporeal membrane oxygenation (VA ECMO) and extracorporeal cardiopulmonary resuscitation (e-CPR) provide viable options for life sustaining measures when medical therapy fails. The purpose of this study is to determine the utilization and outcomes of VA ECMO and eCPR in patients that require emergent cardiac support at a single academic center.

Methods

A retrospective chart review of prospectively collected data was performed at an academic institution from January 1st, 2018 to June 30th, 2020. All consecutive patients who required VA ECMO were evaluated based on whether they underwent traditional VA ECMO or eCPR. The study variables include demographic data, duration on ECMO, length of stay, complications, and survival to discharge.

Results

A total of 90 patients were placed on VA ECMO for cardiac support with 44.4% (40) of these patients undergoing eCPR secondary to cardiac arrest and emergent placement on ECMO. A majority of the patients were male (n = 64, 71.1%) and the mean age was 58.8 ± 15.8 years. 44.4% of patients were transferred from outside hospitals for a higher level of care and 37.8% of patients required another primary therapy such as an Impella or IABP. The most common complication experienced by patients was bleeding (n = 41, 45.6%), which occurred less often in eCPR (n = 29, 58% vs. n = 12, 30%). Other complications included infections (n = 11, 12.2%), limb ischemia (n = 13, 14.4%), acute kidney injury (n = 17, 18.9%), and cerebral vascular accident (n = 4, 4.4%). The length of stay was longer for patients on VA ECMO (32.1 ± 40.7 days vs. 17.7 ± 18.2 days). Mean time on ECMO was 8.1 ± 8.3 days. Survival to discharge was higher in VA ECMO patients (n = 23, 46% vs. n = 8, 20%).

Conclusion

VA ECMO provided an effective rescue therapy in patients in acute cardiogenic shock with a survival greater than the expected ELSO guidelines of 40%. While the survival of eCPR was lower than expected, this may reflect the severity of patient’s condition and emphasizes the importance of careful patient selection and planning.

Nurses' experience of patient care using extracorporeal membrane oxygenation

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) is an advanced form of temporary life support, to aid respiratory and/or cardiac function, which diverts venous blood through an extracorporeal circuit and returns it to the body after gas exchange through a semipermeable membrane. It may be used for oxygenation, carbon dioxide removal, and hemodynamic support. ECMO has been available to patients in Iran for only about 4 years. Because nurses do not widely use ECMO in Intensive Care Units (ICUs), for many it is still a unique experience and more needs to be understood about that experience in order to support nurses in that role.

AIM

This study aimed to explore Iranian nurses' experience of caring for patients receiving ECMO.

METHODS

This interpretive phenomenological study was conducted in Iran in 2019. Semi-structured interviews were conducted in Farsi to collect data from 18 nurses who had cared for patients receiving ECMO. The interviews continued until data saturation, and thematic analysis of the interview transcripts was undertaken.

RESULTS

Following thematic analysis, three main themes of "running on a suspension bridge," "sense of duality," and "bewilderment in the mirage of hope," and with seven sub-themes, emerged.

CONCLUSION

Based on the results of this study, it is proposed that caring for patients receiving ECMO is a source of emotional turmoil for nurses. Nurses are constantly thinking about whether their patients receiving ECMO are recovering or dying, and the nature of this care may lead to stress and burnout. Therefore, it is recommended that these nurses receive counselling and psychological support.

RELEVANCE TO CLINICAL PRACTICE

Nurses are able to provide comprehensive and holistic patient care when they enjoy good physical and mental health themselves. To prevent distress in nurses and to provide safe care for the patient receiving ECMO, provision of psychological support for these nurses is recommended.

Extracorporeal membrane oxygenation combined with continuous renal replacement therapy for the treatment of severe burns: current status and challenges

Severe burns often cause various systemic complications and multiple organ dysfunction syndrome, which is the main cause of death. The lungs and kidneys are vulnerable organs in patients with multiple organ dysfunction syndrome after burns. Extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT) have been gradually applied in clinical practice and are beneficial for severe burn patients with refractory respiratory failure or renal dysfunction. However, the literature on ECMO combined with CRRT for the treatment of severe burns is limited. Here, we focus on the current status of ECMO combined with CRRT for the treatment of severe burns and the associated challenges, including the timing of treatment, nutrition support, heparinization and wound management, catheter-related infection and drug dosing in CRRT. With the advancement of medical technology, ECMO combined with CRRT will be further optimized to improve the outcomes of patients with severe burns.

Joint Society of Critical Care Medicine-Extracorporeal Life Support Organization Task Force Position Paper on the Role of the Intensivist in the Initiation and Management of Extracorporeal Membrane Oxygenation

OBJECTIVES

To define the role of the intensivist in the initiation and management of patients on extracorporeal membrane oxygenation.

DESIGN

Retrospective review of the literature and expert consensus.

SETTING

Series of in-person meetings, conference calls, and emails from January 2018 to March 2019.

SUBJECTS

A multidisciplinary, expert Task Force was appointed and assembled by the Society of Critical Care Medicine and the Extracorporeal Life Support Organization. Experts were identified by their respective societies based on reputation, experience, and contribution to the field.

INTERVENTIONS

A MEDLINE search was performed and all members of the Task Force reviewed relevant references, summarizing high-quality evidence when available. Consensus was obtained using a modified Delphi process, with agreement determined by voting using the RAND/UCLA scale, with score ranging from 1 to 9.

MEASUREMENTS AND MAIN RESULTS

The Task Force developed 18 strong and five weak recommendations in five topic areas of extracorporeal membrane oxygenation initiation and management. These recommendations were organized into five areas related to the care of patients on extracorporeal membrane oxygenation: patient selection, management, mitigation of complications, coordination of multidisciplinary care, and communication with surrogate decision-makers. A common theme of the recommendations is extracorporeal membrane oxygenation is best performed by a multidisciplinary team, which intensivists are positioned to engage and lead.

CONCLUSIONS

The role of the intensivist in the care of patients on extracorporeal membrane oxygenation continues to evolve and grow, especially when knowledge and familiarity of the issues surrounding extracorporeal membrane oxygenation selection, cannulation, and management are applied.

2020 EACTS/ELSO/STS/AATS Expert Consensus on Post-cardiotomy Extracorporeal Life Support in Adult Patients

Post-cardiotomy extracorporeal life support (PC-ECLS) in adult patients has been used only rarely but recent data have shown a remarkable increase in its use, almost certainly due to improved technology, ease of management, growing familiarity with its capability and decreased costs. Trends in worldwide in-hospital survival, however, rather than improving, have shown a decline in some experiences, likely due to increased use in more complex, critically ill patients rather than to suboptimal management. Nevertheless, PC-ECLS is proving to be a valuable resource for temporary cardiocirculatory and respiratory support in patients who would otherwise most likely die. Because a comprehensive review of PC-ECLS might be of use for the practitioner, and possibly improve patient management in this setting, the authors have attempted to create a concise, comprehensive and relevant analysis of all aspects related to PC-ECLS, with a particular emphasis on indications, technique, management and avoidance of complications, appraisal of new approaches and ethics, education and training.

Impact of a Multidisciplinary Team Approach on Extracorporeal Circulatory Life Support-Bridged Heart Transplantation

Background

The number of heart transplantations (HTx) is increasing annually. Due to advances in medical and surgical support, the outcomes of HTx are also improving. Extracorporeal circulatory life support (ECLS) provides patients with decompensated heart failure a chance to undergo HTx. A medical approach involving collaboration among experienced experts in different fields should improve the outcomes and prognosis of ECLS-bridged HTx.

Methods

From December 2003 to December 2018, 1,465 patients received ECLS at Samsung Medical Center. We excluded patients who had not undergone HTx or underwent repeated transplantations. Patients younger than 18 years were excluded. We also excluded patients who received an implantable durable left ventricular assist device before HTx. In total, 91 patients were included in this study. A multidisciplinary team approach began in March 2013 at our hospital. We divided the patients into 2 groups depending on whether they were treated before or after implementation of the team approach.

Results

The 30-day mortality rate was significantly higher in the pre-ECLS team group than in the post-ECLS team group (n=5, 18.5% vs. n=2, 3.1%; p=0.023). The 1-year survival rate was better in the post-ECLS team group than in the pre-ECLS team group (n=57, 89.1% vs. n=19, 70.4%; p=0.023).

Conclusion

We found that implementing a multidisciplinary team approach improved the outcomes of ECLS-bridged HTx. Team-based care should be adapted at HTx centers that perform high-risk HTx.

Recommendations From the Professional Advisory Committee on Nursing Practice in the Care of ECMO-Supported Patients

BACKGROUND

By July 2020, the Extracorporeal Life Support Organization had documented more than 133 000 extracorporeal membrane oxygenation (ECMO) implementations, with more than 61 000 implementations in adult patients. No clear policies regarding the authority and responsibility of nursing staff in the treatment of ECMO-supported patients are currently available.

OBJECTIVE

To formulate evidence-based recommendations for nursing care of ECMO-supported patients.

METHODS

The National Head Nurse's office and the Professional Guidelines Department in the Nursing Division of Israel's Ministry of Health formed the Professional Advisory Committee on Nursing Practice in the Care of ECMO-Supported Patients to address concerns regarding the current state of professional nursing practice in the care of these patients. The Professional Advisory Committee brought together 15 senior Israeli ECMO nursing experts who explored the potential of registered nurses in caring for ECMO-supported patients, considered the competencies of nurses treating ECMO-supported patients, discussed training programs and health care policy, and examined nursing outcomes for quality assurance.

RESULTS

The Professional Advisory Committee formulated recommendations regarding the following priority issues: (1) determining boundaries of professional authority and nurses' responsibilities, including designated activities for different professional ranks of registered nurses; (2) providing appropriate content for the training programs offered, such as generic/basic, above-basic, and clinical specialization nursing programs; and (3) defining relevant quality measures for nursing treatment of ECMO-supported patients.

CONCLUSIONS

Introducing international standards would ensure the safety and effectiveness of nursing care for ECMO-supported patients through quality and risk management and establishment of new evidence-based nursing practices.

Extracorporeal cardiopulmonary resuscitation for cardiac arrest

PURPOSE OF REVIEW

Extracorporeal cardiopulmonary resuscitation (ECPR) is a contemporary resuscitation approach that employs veno-arterial extracorporeal membrane oxygenation (VA-ECMO). This approach is increasingly used worldwide to mitigate the widespread hemodynamic and multiorgan dysfunction that accompanies cardiac arrest.

RECENT FINDINGS

In this review, the physiology of VA-ECMO and ECPR, the role of ECPR in contemporary resuscitation care, the complications associated with ECPR and VA-ECMO usage, and intensive care considerations for this population are discussed.

SUMMARY

ECPR offers a promising mechanism to mitigate multiorgan injury and allow time for the institution of supportive interventions required to effectively treat cardiac arrest. More prospective data in the context of extensive prehospital and hospital collaboration is needed to promote its successful use.

Safety, Tolerability, and Outcomes of Enteral Nutrition in Extracorporeal Membrane Oxygenation

Extracorporeal membrane oxygenation (ECMO) is a supportive care system for patients with respiratory or cardiac failure. Patients requiring ECMO are at risk for significant inflammation, prolonged hospitalization, and acquired malnutrition and sarcopenia. Societal guidelines recommend early enteral nutrition in critically ill patients; however, in this population, optimal timing and dose of nutrition remains unknown and fear of reduced splanchnic perfusion, delayed gastric emptying, and bowel ischemia poses a barrier to appropriate energy and protein intake. This narrative review intends to provide an overview of ECMO, highlight the rationale for nutrition support in this population, and review the safety, tolerability, and outcomes associated with enteral nutrition during ECMO.

2020 EACTS/ELSO/STS/AATS expert consensus on post-cardiotomy extracorporeal life support in adult patients

Post-cardiotomy extracorporeal life support (PC-ECLS) in adult patients has been used only rarely but recent data have shown a remarkable increase in its use, almost certainly due to improved technology, ease of management, growing familiarity with its capability and decreased costs. Trends in worldwide in-hospital survival, however, rather than improving, have shown a decline in some experiences, likely due to increased use in more complex, critically ill patients rather than to suboptimal management. Nevertheless, PC-ECLS is proving to be a valuable resource for temporary cardiocirculatory and respiratory support in patients who would otherwise most likely die. Because a comprehensive review of PC-ECLS might be of use for the practitioner, and possibly improve patient management in this setting, the authors have attempted to create a concise, comprehensive and relevant analysis of all aspects related to PC-ECLS, with a particular emphasis on indications, technique, management and avoidance of complications, appraisal of new approaches and ethics, education and training.

Evolving Role of Anesthesiology Intensivists in Cardiothoracic Critical Care

The role of cardiothoracic anesthesiology intensivists has expanded over the past few decades. Cardiothoracic anesthesiology intensivists are taking on larger roles in cardiac critical care specializing in cardiogenic shock and extracorporeal membrane oxygenation.

A 266 Patient Experience of a Quaternary Care Referral Center for Extracorporeal Membrane Oxygenation with Assessment of Outcomes for Transferred Versus In-House Patients

OBJECTIVE

Patients undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO) require highly trained specialists and resources to be cared for safely. Interestingly, comparisons of outcomes for patients cannulated for VA-ECMO by outside institutions and transferred to referral centers for further care versus those cannulated and taken care of in house at the referral center have not been reported on a large scale. This study aimed to perform the first comparison of these 2 populations based on the experience of a single quaternary referral center.

DESIGN

A retrospective chart review-based study in a single quaternary care center of patients cannulated by referring institutions for VA-ECMO then transferred versus patients who were cannulated in house was performed to assess for a difference in survival (both of ECMO therapy and survival to discharge).

SETTING

Single quaternary academic referral center for ECMO.

PARTICIPANTS

All patients undergoing VA-ECMO who were at least 18 years old from 2011-2018 (266 patients).

INTERVENTION

None.

MEASUREMENTS AND MAIN RESULTS

The study comprised 215 patients cannulated for VA-ECMO in house and 51 patients cannulated by 17 different outside institutions then transferred. Survival of the ECMO run for in-house patients (122/215) was 56.7% (95% confidence interval [CI] 50.1-63.3), and survival of transferred patients (31/51) for the ECMO run was 60.8% (95% CI 47.4-74.2; p = 0.58). Survival to discharge in patients cannulated in house (82/215) was 38.1% (95% CI 31.6-44.6) and for outside hospital transfers (24/51 patients) was 47.1% (95% CI 33.4-60.8; p = 0.23).

CONCLUSIONS

This retrospective chart review of 266 patients found no difference in survival of the ECMO therapy or survival to discharge in patients cannulated by other institutions and transferred versus those who were cannulated in house. Even though analysis on the feasibility of transfer centers has been performed extensively in patients with respiratory failure requiring venovenous ECMO, minimal investigation has been performed in patients requiring VA-ECMO. These results should be considered hypothesis-generating because larger sample sizes are necessary to guide care of these patients more definitively.
