Concurrent veno-pulmonary extracorporeal membrane oxygenation cannulation with ProtekDuo parallel to an in situ veno-pulmonary single-lumen cannula.

This technical report describes the successful transition from dual lumen, single site veno-venous extracorporeal membrane oxygenation ((dl)V-V ECMO) to single lumen, dual site veno-pulmonary (V-P) ECMO, and subsequently to dual lumen, single site (dl)V-P ECMO involving temporary placement of two cannulas in the main pulmonary artery. No complications were observed during these transitions. This technique could address concerns related to cannula exchanges in VP ECMO. However, caution is warranted and constant monitoring of cannula position using real-time imaging is required when using this technique due to the risk profile.

Implementation of a Pediatric Telemedicine and Medication Delivery Service in a Resource-limited Setting: A Pilot Study for Clinical Safety and Feasibility.

OBJECTIVE: Determine the clinical safety and feasibility of implementing a telemedicine and medication delivery service (TMDS) to address gaps in nighttime access to health care for children in low-resource settings. STUDY DESIGN: We implemented a TMDS called 'MotoMeds' in Haiti as a prospective cohort study. A parent/guardian of a sick child ≤ 10 years contacted the call center (6 PM-5 AM). A nurse provider used decision support tools to triage cases (mild, moderate, or severe). Severe cases were referred to emergency care. For nonsevere cases, providers gathered clinical findings to generate an assessment and plan. For cases within the delivery zone, a provider and driver were dispatched and the provider performed a paired in-person exam as a reference standard for the virtual call center exam. Families received a follow-up call at 10 days. Data were analyzed for clinical safety and feasibility. RESULTS: A total of 391 cases were enrolled from September 9, 2019, to January 19, 2021. Most cases were nonsevere (92%; 361); household visits were completed for 89% (347) of these cases. Among the 30 severe cases, 67% (20) sought referred care. Among all cases, respiratory problems were the most common complaint (63%; 246). At 10 days, 95% (329) of parents reported their child had "improved" or "recovered". Overall, 99% (344) rated the TMDS as "good" or "great". The median phone consultation time was 20 minutes, time to household arrival was 73 minutes, and total case time was 114 minutes. CONCLUSION: The TMDS was a feasible health care delivery model. Although many cases were likely self-limiting, the TMDS was associated with high rates of reported improvement in clinical status at 10 days. TRIAL REGISTRATION: clinicaltrials.gov: NCT03943654.

Evaluating the prerequisites for adapting a paediatric nighttime telemedicine and medication delivery service to a setting with high malarial burden: A cross-sectional pre-implementation study.

OBJECTIVE: We sought to evaluate the prerequisites (demand, interest, feasibility) for adapting a paediatric nighttime telemedicine and medication delivery service (TMDS) to Ghana. METHODS: A cross-sectional survey of households and associated healthcare providers was conducted in urban and rural Ghana. Households were identified through randomised geospatial sampling; households with at least one child <10 years were enrolled. Household surveys collected information relating to demographics, household resources, standardised case scenarios, recent paediatric health events, satisfaction with healthcare access, and interest in TMDS intervention models. Providers were identified by households and enrolled. Provider surveys collected provider type, hours of operation, services, and opinions of a TMDS model. RESULTS: A total of 511 (263 urban, 248 rural) households and 18 providers (10 urban, 8 rural) were surveyed. A total of 262 health events involving children <10 years were reported, of which 47% occurred at night. Care was sought for >70% of health events presenting at night; however, care-seeking was delayed until morning or later for >75% of these events; 54% of households expressed dissatisfaction with their current access to paediatric care at night; 99% of households expressed that a nighttime TMDS service for children would be directly useful to their families. Correspondingly, 17 of 18 providers stated that a TMDS was needed in their community; >99% of households had access to a cellular phone. All households expressed willingness to use their phones to call a TMDS and allow a TMDS provider into their homes at night. Willingness to pay and provider-recommended price points varied by setting. CONCLUSIONS: Prerequisites for adapting a TMDS to Ghana were met. A nighttime paediatric TMDS service was found to be needed, appealing, and feasible in Ghana. These data motivate the adaptation of a TMDS to urban and rural Ghana.

Unrecognized cardiac arrests: A one-year review of audio from emergency medical dispatch calls.

OBJECTIVES: Immediate recognition of out-of-hospital cardiac arrest (OHCA) by Emergency Medical Dispatch (EMD) operators is crucial to facilitate timely initiation of telephone cardiopulmonary resuscitation (T-CPR) and to enable the appropriate level of Emergency Medical Services (EMS) response. The goal of this study was to identify patterns that can increase EMD-level recognition of cardiac arrests prior to EMS arrival. METHODS: The Combined Communications Center in Alachua County, Florida provided audio recordings of all emergency calls from January 1, 2018 to November 16, 2018 dispatched as a chief complaint other than OHCA, but later identified as cardiac arrest. A multi-disciplinary medical team transcribed and analyzed the calls to determine common themes and trends. RESULTS: Out of an initial 81 calls meeting inclusion criteria, 69 were immediately recognized as OHCA by EMDs, leaving 12 calls of unrecognized OHCA. In 11 of 12 calls respiratory issues were described to EMD. In 10 of 12 calls the subject was described as unconscious, and in the other 2 calls, the subject lost consciousness during the call. CONCLUSIONS: Lack of recognition of OHCA by EMD occurred in most calls due to difficulty communicating the subject's respiratory status. Further emphasis should be placed on identifying non-viable respirations in unconscious patients in EMD training and algorithms to increase recognition of OHCA and initiation of T-CPR. A multi-year review of a comparable dataset from geographically and socioeconomically diverse regions in the United States can validate and expand these preliminary trends.

Patient, Neighborhood, and Spatial Determinants of Out-of-Hospital Cardiac Arrest Outcomes Throughout the Chain of Survival: A Community-Oriented Multilevel Analysis.

Objective: Global and national trends of out-of-hospital cardiac arrest (OHCA) have been examined; however, geographic variation and socioeconomic disparities of OHCA outcomes in the community setting are less understood. We developed and tested a replicable, community-oriented assessment strategy aimed to identify spatial variations in OHCA outcomes using socioeconomic, prehospital, and in-hospital factors. Methods: Emergency medical service (EMS) records of adult, non-traumatic OHCA within Alachua County, FL (2012-2017) were retrospectively reviewed and matched to corresponding medical records at the University of Florida (UF). Incidence of cardiac arrest was geocoded to census tracts and connected to U.S. census socioeconomic attribute data. Primary outcomes include survival to emergency department (ED), hospital admission, discharge, and discharge to home. Multilevel mixed-effects logistic regression models were developed to assess sub-county geographic variance, probabilities of survival, and prehospital risk factors. Getis-Ord Gi statistic and Moran's I-test was applied to assess spatial clustering in outcome survival rates. Results: Of the 1562 OHCA cases extracted from EMS records, 1,335 (85.5%) were included with 372 transported to study site. Predicted probability of survival to ED was 57.0% (95CI: 51.3-62.3%). Of transported cases to study site ED, predicted probabilities of survival was to 41.7% (95CI: 36.1-47.6%) for hospital admission, 16.1% (95CI: 10.7-23.5%) for hospital discharge, and 7.1% (95CI: 3.7-13.3%) for home discharge. Census tracts accounted for significant variability in survival to ED (p < 0.001), discharge (p = 0.031), and home discharge outcomes (p = 0.036). There was no significant geographic variation in survival to admission outcome. Neighborhood-level factors significantly improved model fit for survival to ED, discharge, and discharge home outcomes. Multiple modifiable patient- and neighborhood-level variables of interest were identified, including rural-urban differences. Conclusion: We identified important geographic disparities that exist in OHCA outcomes at the community level. By using a replicable schematic, this variation can be explained through community-oriented modifiable socioeconomic and prehospital factors.

Bystander Assistance for Trauma Victims in Low- and Middle-Income Countries: A Systematic Review of Prevalence and Training Interventions.

OBJECTIVE: Lack of organized prehospital care may contribute to the disproportionate burden of trauma-related deaths in low- and middle-income countries (LMICs). The World Health Organization (WHO) recommends bystander training in basic principles of first aid and victim transport; however, prevalence of bystander or layperson assistance to trauma victims in LMICs has not been well-described, and organized reviews of existing evidence for bystander training are lacking. This systematic review aims to 1) describe the prevalence of bystander or layperson aid or transport for trauma victims in the prehospital setting in LMICs and 2) ascertain impacts of bystander training interventions in these settings. METHODS: A systematic search of OVID Medline, Cochrane Library, and relevant gray literature was conducted. We included 1) all studies detailing prevalence of bystander-administered aid or transport for trauma victims in LMICs and 2) all randomized controlled trials and observational studies evaluating bystander training interventions. We extracted study characteristics, interventions, and outcomes data. Study quality was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. RESULTS: Sixty-two studies detailed prevalence of bystander transport and aid. Family members, police, and bus or taxi drivers commonly transported patients; a majority of patients, up to >94%, received aid from bystanders. Twenty-four studies examined impacts of training interventions. Only one study looked at transport interventions; the remainder addressed first aid training. Interventions varied in content, duration, and target learners. Evidence was generally of low quality, but all studies demonstrated improvements in layperson knowledge and skills. Five studies reported a mortality reduction. CONCLUSIONS: Heterogeneity in data reporting and outcomes limited formal meta-analysis. However, this review shows high rates of bystander involvement in prehospital trauma care and transport in LMICs and highlights the need for bystander training. Bystander training in these settings is feasible and may have an important impact on meaningful outcomes such as mortality. Categories of involved bystanders varied by region and training interventions should be targeted at relevant groups. "Train the trainer" models appear promising in securing community engagement and maximizing participation. Further research is needed to examine the value of bystander transport networks in trauma.

Paramedic determination of appropriate emergency department destination.

BACKGROUND: Freestanding emergency departments (FSED) are equipped to care for most emergencies, but do not have all the resources that hospital-based emergency departments (ED) offer. As the number of FSEDs grows rapidly, emergency medical services (EMS) must routinely determine whether a FSED is an appropriate destination. Inappropriate triage may delay definitive care, potentially increasing morbidity, mortality, and resource utilization. We sought to evaluate paramedics' ability in determining whether a FSED is the most appropriate destination. METHODS: We conducted a retrospective study of two county EMS agencies and two FSEDs over a 25-month period in Alachua and Levy County, Florida, USA. Both EMS agencies allow paramedic discretion in determining transport destination. To determine whether paramedics can correctly identify patients that can be cared for fully at a FSED, our primary outcome was the percentage of patients transported to FSEDs by EMS that were discharged without additional hospital-based resources. RESULTS: We identified 1247 EMS patients that had a selected destination of FSED. We excluded patients that did not arrive at their selected FSED destination, left before FSED disposition, or were transferred from the FSED to unaffiliated hospitals. A total of 1184 patients were included for analysis, and 885 (74.7%) did not require additional hospital resources. Comparing the two EMS agencies yielded similar results. CONCLUSION: In this study, involving two EMS agencies over a 25-month period, we found that 3 out of 4 patients deemed appropriate for transport to a FSED by a paramedic did not require additional hospital-based services.

Public perception towards bystander cardiopulmonary resuscitation.

OBJECTIVE: Bystander cardiopulmonary resuscitation (CPR) after out-of-hospital cardiac arrest (OHCA) improves survival and neurological outcomes. Nonetheless, many OHCA patients do not receive bystander CPR during a witnessed arrest. Our aim was to identify potential barriers to bystander CPR. METHODS: Participants at CPR training events conducted in the USA between February and May 2018 answered a 14-question survey prior to training. Respondents were asked about their overall comfort level performing CPR, and about potential concerns specific to performing CPR on a middle-aged female, a geriatric male, and male and female adolescent patients. Open-ended responses were analysed qualitatively by categorising responses into themes. RESULTS: Of the 677 participants, 582 (86.0%) completed the survey, with 509 (88.1%) between 18 and 29 years of age, 341 (58.6%) without prior CPR training and 556 (96.0%) without prior CPR experience. Across all four scenarios of patients in cardiac arrest, less than 65% of respondents reported that they would be 'Extremely Likely' (20.6%-29.1%) or 'Moderately Likely' (26.9%-34.8%) to initiate CPR. The leading concerns were 'causing injury to patient' for geriatric (n=193, 63.1%), female (n=51, 20.5%) and adolescent (n=148, 50.9%) patients. Lack of appropriate skills was the second leading concern when the victim was a geriatric (n=41, 13.4%) or adolescent (n=68, 23.4%) patient, whereas for female patients, 35 (14.1%) were concerned about exposing the patient or the patient's breasts interfering with performance of CPR and 15 (6.0%) were concerned about being accused of sexual assault. Significant differences were observed in race, ethnicity and age regarding the likelihood of starting to perform CPR on female and adolescent patients. CONCLUSIONS: Participants at CPR training events have multiple concerns and fears related to performing bystander CPR. Causing additional harm and lack of skills were among the leading reservations reported. These findings should be considered for improved CPR training and public education.

Feasibility of Paramedic Performed Prehospital Lung Ultrasound in Medical Patients with Respiratory Distress.

OBJECTIVE: Prehospital ultrasound is not yet widely implemented. Most studies report on convenience samples and trauma patients, often by prehospital physicians or critical care clinicians. We assessed the feasibility of paramedic performed prehospital lung ultrasound in medical patients with respiratory distress. METHODS: Paramedics at 2 ambulance stations in the city of Pittsburgh, Pennsylvania, USA underwent a 2-hour training session in prehospital lung ultrasound using the SonoSite iViz, a handheld ultrasound device. Emergency medical services (EMS) command center (EMS-CC) physicians were instructed in the interpretation of lung ultrasound images. Paramedics enrolled patients presenting with signs and symptoms of respiratory distress over a 3-month period. The ultrasound exam included anterior and lateral views from both sides of the chest. Images were transmitted wirelessly using a mobile hotspot device and uploaded into an online image archiving system. Images were interpreted remotely by the EMS-CC physicians, and 2 expert sonographers provided an overread. We assessed agreement between EMS-CC physicians and experts, as well as between chart-review derived ED diagnosis and both EMS-CC physician and expert interpretation. We defined four a priori hypotheses that would need to be met for the intervention to be considered "feasible." RESULTS: A total of 34 of 78 (43.6%) eligible patients had an ultrasound exam completed. Image transmission was successful in 25 (73.5%) of cases where ultrasound was performed. The primary reason for not enrolling an otherwise eligible patient was equipment failure (25.0%), followed by patient acuity and patient refusal (18.2% each). A total of 20 (58.8%) completed scans were deemed uninterpretable upon expert review. Agreement between EMS physicians and experts was poor. Agreement between EMS-CC physicians and ED diagnosis, as well as between experts and ED diagnosis, was fair. The predetermined thresholds for feasibility were not met. CONCLUSIONS: Paramedic performed prehospital lung ultrasound for patients with respiratory distress and remote interpretation by EMS physicians did not meet the predetermined thresholds to be considered "feasible" in a real-world environment with currently available technologies. This study identified important barriers to the implementation of prehospital lung ultrasound, which should be addressed in future studies.

Skill and knowledge retention after training in cardiopulmonary ultrasound in Ghana: an impact assessment of bedside ultrasound training in a resource-limited setting.

OBJECTIVE: Brief training courses in bedside ultrasound are commonly done by visiting faculty in low-income and middle-income countries, and positive short-term effects have been reported. Long-term outcomes are poorly understood. We held a training course on a cardiopulmonary ultrasound (CPUS) protocol over two separate 10-day periods in 2016. In 2017, 9-11 months after the initial training, we assessed skill and knowledge retention as well as perceived impact on local practice. METHODS: A written test using six clinical vignettes and an observed structured clinical examination were used to assess theoretical knowledge and practical skills. Additionally, in-person interviews and a written survey were completed with the physicians who had participated in the initial training. RESULTS: All 20 participants passed the written and clinical examination. The median follow-up test score was 10 out of 12, compared with a median score of 12 on a test completed immediately after the initial training. Physicians identified the ability to narrow their differential diagnosis and to initiate critical interventions earlier than without ultrasound as a key benefit of the CPUS training. They rated the cardiac, abdominal and inferior vena cava components of the CPUS protocol as most relevant to their everyday practice. CONCLUSION: Long-term ultrasound knowledge and skill retention was high after a brief and intensive training intervention at an academic tertiary hospital in Ghana. Clinicians reported improvements in patient care and local practice patterns.

Impact of nutrition interventions on pediatric mortality and nutrition outcomes in humanitarian emergencies: A systematic review.

OBJECTIVES: Malnutrition contributes to paediatric morbidity and mortality in disasters and complex emergencies, but summary data describing specific nutritional interventions in these settings are lacking. This systematic review aimed to characterise such interventions and their effects on paediatric mortality, anthropometric measures and serum markers of nutrition. METHODS: A systematic search of OVID MEDLINE, Cochrane Library and relevant grey literature was conducted. We included all randomised controlled trials and observational controlled studies evaluating effectiveness of nutritional intervention(s) on defined health outcomes in children and adolescents (0-18 years) within a disaster or complex emergency. We extracted study characteristics, interventions and outcomes data. Study quality was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. RESULTS: A total of 31 studies met inclusion criteria. Most were conducted in Africa (17), during periods of conflict or hunger gaps (14), and evaluated micronutrient supplementation (14) or selective feeding (10). Overall study quality was low, with only two high and four moderate quality studies. High- and medium-quality studies demonstrated positive impact of fortified spreads, ready-to-use therapeutic foods, micronutrient supplementation, and food and cash transfers. CONCLUSION: In disasters and complex emergencies, high variability and low quality of controlled studies on paediatric malnutrition limit meaningful data aggregation. If existing research gaps are to be addressed, the inherent unpredictability of humanitarian emergencies and ethical considerations regarding controls may warrant a paradigm shift in what constitutes adequate methods. Periodic hunger gaps may offer a generalisable opportunity for robust trials, but consensus on meaningful nutritional endpoints is needed.

Cardiopulmonary ultrasound for critically ill adults improves diagnostic accuracy in a resource-limited setting: the AFRICA trial.

OBJECTIVE: To assess the effects of a cardiopulmonary ultrasound (CPUS) examination on diagnostic accuracy for critically ill patients in a resource-limited setting. METHODS: Approximately half of the emergency medicine resident physicians at the Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, were trained in a CPUS protocol. Adult patients triaged to the resuscitation area of the emergency department (ED) were enrolled if they exhibited signs or symptoms of shock or respiratory distress. Patients were assigned to the intervention group if their treating physician had completed the CPUS training. The physician's initial diagnostic impression was recorded immediately after the history and physical examination in the control group, and after an added CPUS examination in the intervention group. This was compared to a standardised final diagnosis derived from post hoc chart review of the patient's care at 24 h by two blinded, independent reviewers using a clearly defined and systematic process. Secondary outcomes were 24-h mortality and use of IV fluids, diuretics, vasopressors and bronchodilators. RESULTS: Of 890 patients presenting during the study period, 502 were assessed for eligibility, and 180 patients were enrolled. Diagnostic accuracy was higher for patients who received the CPUS examination (71.9% vs. 57.1%, Δ 14.8% [CI 0.5%, 28.4%]). This effect was particularly pronounced for patients with a 'cardiac' diagnosis, such as cardiogenic shock, congestive heart failure or acute valvular disease (94.7% vs. 40.0%, Δ 54.7% [CI 8.9%, 86.4%]). Secondary outcomes were not different between groups. CONCLUSIONS: In an urban ED in Ghana, a CPUS examination improved the accuracy of the treating physician's initial diagnostic impression. There were no differences in 24-h mortality and a number of patient care interventions.

Sustainable Resuscitation Ultrasound Education in a Low-Resource Environment: The Kumasi Experience.

BACKGROUND: Point-of-care-ultrasound (POCUS) is an increasingly important tool for emergency physicians and has become a standard component of emergency medicine residency training in high-income countries. Cardiopulmonary ultrasound (CPUS) is emerging as an effective way to quickly and accurately assess patients who present to the emergency department with shock and dyspnea. Use of POCUS, including CPUS, is also becoming more prevalent in low- and middle-income countries (LMICs); however, formal ultrasound training for emergency medicine resident physicians in these settings is not widely available. OBJECTIVES: To evaluate the feasibility of integrating a high-intensity ultrasound training program into the formal curriculum for emergency medicine resident physicians in an LMIC. METHODS: We conducted a pilot ultrasound training program focusing on CPUS for 20 emergency medicine resident physicians in Kumasi, Ghana, which consisted of didactic sessions and hands-on practice. Competency was assessed by comparing pretest and posttest scores and with an Objective Structured Clinical Examination (OSCE) performed after the final training session. RESULTS: The mean score on the pretest was 61%, and after training, the posttest score was 96%. All residents obtained passing scores above 70% on the OSCE. CONCLUSION: A high-intensity ultrasound training program can be successfully integrated into an emergency medicine training curriculum in an LMIC.

The use of portable ultrasound devices in low- and middle-income countries: a systematic review of the literature.

OBJECTIVES: To review the scientific literature pertaining to the use of hand-carried and hand-held ultrasound devices in low- and middle-income countries (LMIC), with a focus on clinical applications, geographical areas of use, the impact on patient management and technical features of the devices used. METHODS: The electronic databases PubMed and Google Scholar were searched. No language or date restrictions were applied. Case reports and original research describing the use of hand-carried ultrasound devices in LMIC were included if agreed upon as relevant by two-reviewer consensus based on our predefined research questions. RESULTS: A total of 644 articles were found and screened, and 36 manuscripts were included for final review. Twenty-seven studies were original research articles, and nine were case reports. Several reports describe the successful diagnosis and management of difficult, often life-threatening conditions, using hand-carried and hand-held ultrasound. These portable ultrasound devices have also been studied for cardiac screening exams, as well as a rapid triage tool in rural areas and after natural disaster. Most applications focus on obstetrical and abdominal complaints. Portable ultrasound may have an impact on clinical management in up to 70% of all cases. However, no randomised controlled trials have evaluated the impact of ultrasound-guided diagnosis and treatment in resource-constrained settings. The exclusion of articles published in journals not listed in the large databases may have biased our results. Our findings are limited by the lack of higher quality evidence (e.g. controlled trials). CONCLUSIONS: Hand-carried and hand-held ultrasound is successfully being used to triage, diagnose and treat patients with a variety of complaints in LMIC. However, the quality of the current evidence is low. There is an urgent need to perform larger clinical trials assessing the impact of hand-carried ultrasound in LMIC.

A WINning Technique: The Wire-in-Needle Feasibility Study.

BACKGROUND: Dynamic ultrasound guidance reduces complications associated with central venous catheter placement. However, successful central venous cannulation often remains challenging, particularly in hypotensive patients. The new wire-in-needle (WIN) technique can further increase periprocedural safety. Here, a needle is "preloaded" with a guidewire that is then advanced toward the tip of needle. The vein is then cannulated using long-axis ultrasound guidance. OBJECTIVE: To evaluate the feasibility and safety profile of the WIN technique. METHODS: Medical students, and resident and attending physicians participated in this study. After a brief lecture and practice session on the WIN technique, they underwent a skills assessment evaluating different aspects of both techniques. Participants then completed a survey assessing their prior experience regarding procedural ultrasound, and their assessment of the WIN technique. RESULTS: Sixty clinicians participated. The assessment of both techniques revealed no significant differences in the number of needle redirections, cannulation attempts, number of arterial punctures, or overall dexterity with the procedure. The WIN technique was faster (45.9 vs. 61.5 s, p = 0.0005) than the traditional technique. More participants confirmed the accurate position of the guidewire in the vein (75% vs. 95%, p = 0.002). More than 90% of study participants met the predefined safety aspects of the WIN technique. Almost all participants reported that they plan on using the WIN technique in their clinical practice. CONCLUSION: This study demonstrates that the WIN technique can be learned quickly and easily by clinicians with various levels of training. In this study, using manikins, it was as successful and safe as the traditional short-axis approach.

An educational measure to significantly increase critical knowledge regarding interfacility patient transfers.

BACKGROUND: Patient transfers among medical facilities are high-risk situations. Despite this, there is very little training of physicians regarding the medical and legal aspects of transport medicine. OBJECTIVES: To examine the effects of a one hour, educational intervention on Emergency Medicine (EM) residents' and Critical Care (CC) fellows' knowledge regarding the medical and legal aspects of interfacility patient transfers. METHODS: Prior to the intervention, physician knowledge regarding 12 key concepts in patient transfer was assessed using a pre-test instrument. A one hour, interactive, educational session followed immediately thereafter. Following the intervention, a post-intervention test was given between two and four weeks after delivery. Participants were also asked to describe any prior transportation-medicine-related education, their opinions as they relate to the relevance of the topic, and their comfort levels with patient transfers before and after the intervention. RESULTS: Only a minority of participants had received any formal training in patient transfers prior to the intervention, despite dealing with patient transfers on a frequent, often daily, basis. Both groups improved in several categories on the post-intervention test. They reported improved comfort levels with the medicolegal aspects of interfacility patient transfers after the intervention and felt well-prepared to manage transfers in their daily practice. CONCLUSION: A one hour, educational intervention objectively increased EM and CC physician trainees' understanding of some of the medicolegal aspects of interfacility patient transfers. The study demonstrated a lack of previous training on this important topic and improved levels of comfort with transfers after study participation.

Venovenous ECMO for Acute Chronic Heart Failure after Bilateral Lung Transplantation.

ABSTRACT: Venovenous (VV) ECMO is rarely used during decompensated circulatory states. Although VA ECMO is the routine option, VV ECMO may be an option in selected patients. We present a case of pulmonary edema due to acute heart failure in a patient 4- and 12-year post-lung transplantation who received VV ECMO. Using a thoughtful cannulation strategy, VV ECMO, and aggressive ultrafiltration, the patient was successfully decannulated, extubated, and discharged from the hospital. In cardiogenic pulmonary edema, VV ECMO represents an additional, and likely under-utilized tool, especially in patients who are at high risk for ventilator-associated lung injury. Cannula location and size should be given additional consideration to potentially transition to V-AV ECMO configuration if necessary.

Outcome of Veno-Pulmonary Extracorporeal Life Support in Lung Transplantation Using ProtekDuo Cannula: A Systematic Review and Description of Configurations.

Background: Refractory end-stage pulmonary failure may benefit from extracorporeal life support (ECLS) as a bridge to lung transplantation. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) has been recommended for patients who have failed conventional medical therapy and mechanical ventilation. Veno-arterial (VA) ECMO may be used in patients with acute right ventricular (RV) failure, haemodynamic instability, or refractory respiratory failure. Peripheral percutaneous approaches, either dual-site single-lumen cannulation for veno-pulmonary (VP) ECMO or single-site dual-lumen (dl)VP ECMO, using the ProtekDuo right ventricular assist device (RVAD) cannula, has made this configuration a desirable option as a bridge to transplantation. These configurations support the right ventricle, prevent recirculation by placing the tricuspid and pulmonary valve between the drainage and return cannulas, provide the direct introduction of oxygenated blood into the pulmonary artery, and have been shown to decrease the incidence of acute kidney injury (AKI), requiring continuous renal replacement therapy (CRRT) in certain disease states. This promotes haemodynamic stability, potential sedation-weaning trials, extubation, mobilisation, and pre-transplant rehabilitation. Methods: A web-based literature search in PubMed and EMBASE was undertaken based on a combination of keywords. The PICOS and PRISMA approaches were used. Results: Four case series were identified out of 323 articles, with a total of 34 patients placed on VP ECMO as a bridge to lung transplantation. All relevant data are reviewed and integrated into the Discussion. Conclusions: Despite the limited available evidence, the use of ProtekDuo has become very promising for the management of end-stage lung disease as a bridge to lung transplantation.

Successful Extracorporeal Cardiopulmonary Resuscitation Despite Aortic Occlusion.

We present the case of a 62-year-old man with severe coronary artery disease who presented to the hospital in refractory ventricular fibrillation cardiac arrest. He showed signs of life despite prolonged resuscitation. We thus decided to initiate extracorporeal cardiopulmonary resuscitation (ECPR). The patient had a known total occlusion of his infrarenal aorta that had been surgically bypassed with a bifemoral-axillary graft. We successfully initiated ECPR via the surgical graft, establishing blood flow to the central circulation through the axillary artery in a peripheral configuration while ensuring blood flow to the left leg via the femoral-femoral graft. The patient was extubated neurologically intact the following day and subsequently underwent coronary artery bypass graft surgery while on extracorporeal membrane oxygenation (ECMO) support. He was subsequently weaned off inotropic support and decannulated from ECMO. He was discharged home neurologically intact and independent in his activities of daily living. This case demonstrates that cannulation for ECPR via a surgical vascular graft is possible and that a total occlusion of the infrarenal aorta in the presence of a surgical bypass is not an absolute contraindication to ECMO.

Ethical challenges in Emergency Medical Services: controversies and recommendations.

Emergency Medical Services (EMS) providers face many ethical issues while providing prehospital care to children and adults. Although provider judgment plays a large role in the resolution of conflicts at the scene, it is important to establish protocols and policies, when possible, to address these high-risk and complex situations. This article describes some of the common situations with ethical underpinnings encountered by EMS personnel and managers including denying or delaying transport of patients with non-emergency conditions, use of lights and sirens for patient transport, determination of medical futility in the field, termination of resuscitation, restriction of EMS provider duty hours to prevent fatigue, substance abuse by EMS providers, disaster triage and difficulty in switching from individual care to mass-casualty care, and the challenges of child maltreatment recognition and reporting. A series of ethical questions are proposed, followed by a review of the literature and, when possible, recommendations for management.
