RESUMEN
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.
RESUMEN
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.

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.
RESUMEN
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.
RESUMEN
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.

Background: Severe acute respiratory infections (SARIs) are the leading cause of paediatric death globally, particularly in low- and middle-income countries (LMICs). Given the potential rapid clinical decompensation and high mortality rate from SARIs, interventions that facilitate the early care are critical to improving patient outcomes. Through this systematic review, we aimed to evaluate the impact of emergency care interventions on improving clinical outcomes of paediatric patients with SARIs in LMICs. Methods: We searched PubMed, Global Health, and Global Index Medicus for peer-reviewed clinical trials or studies with comparator groups published before November 2020. We included all studies which evaluated acute and emergency care interventions on clinical outcomes for children (29 days to 19 years) with SARIs conducted in LMICs. Due to observed heterogeneity of interventions and outcomes, we performed narrative synthesis. We assessed bias using the Risk of Bias 2 and Risk of Bias in Non-Randomized Studies of Interventions tools. Results: We screened 20 583, 99 of which met the inclusion criteria. Conditions studied included pneumonia or acute lower respiratory infection (61.6%) and bronchiolitis (29.3%). Studies evaluated medications (80.8%), respiratory support (14.1%), and supportive care (5%). We found the strongest evidence of benefit for decreasing risk of death for respiratory support interventions. Results were inconclusive on the utility of continuous positive airway pressure (CPAP). We found mixed results for interventions for bronchiolitis, but a possible benefit for hypertonic nebulised saline to decrease hospital length of stay. Early use of adjuvant treatments such as Vitamin A, D, and zinc for pneumonia and bronchiolitis did not appear to have convincing evidence of benefit on clinical outcomes. Conclusions: Despite the high global burden of SARI in paediatric populations, few emergency care (EC) interventions have high quality evidence for benefit on clinical outcomes in LMICs. Respiratory support interventions have the strongest evidence for benefit. Further research on the use of CPAP in diverse settings is needed, as is a stronger evidence base for EC interventions for children with SARI, including metrics on the timing of interventions.

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.

OBJECTIVES: Deep hypothermic circulatory arrest (DHCA) is often required for patients undergoing repair of descending thoracic aortic aneurysm (DTAA) or thoracoabdominal aortic aneurysm via left thoracotomy when proximal crossclamping is not feasible or when aneurysmal disease extends into the transverse aortic arch. Historical literature suggests higher complications rates due to the technical complexity of this approach; we examined outcomes with this approach at our center. METHODS: Between January 2008 and May 2018, 84 patients with DTAA or Crawford extent I thoracoabdominal aortic aneurysm underwent open repair. DHCA was employed in 46 of 84 (55%) patients, of which 33 (72%) required repair of distal arch and DTAA, and 13 (28%) required repair of the distal arch and extent I thoracoabdominal aortic aneurysm. Patients who underwent DHCA had more chronic dissections than those in the non-DHCA group (70% vs 34%; P ≤ .05). RESULTS: Major adverse outcomes for the DHCA group versus non-DHCA group were as follows: early mortality 3 out of 46 (7%) versus 4 out of 38 (11%) (P = .70), stroke 3 out of 46 (7%) versus 1 out of 38 (3%) (P = .62), permanent spinal cord deficit 2 out of 46 (4%) versus 3 out of 38 (8%) (P = .65), permanent renal failure necessitating dialysis 1 out of 46 (2%) versus 2 out of 38 (5%) (P = .59). Freedom from major adverse outcomes was 38 out of 46 (83%) versus 31 out of 38 (82%) for DHCA versus non-DHCA (P = 1). CONCLUSIONS: DHCA can be employed via left thoracotomy for combined arch and DTAA or extent I thoracoabdominal aortic aneurysm open repair.

Background: Severe acute respiratory infections (SARIs) remain a leading cause of death globally, particularly in low- and middle-income countries (LMICs). Early intervention is critical, considering the potential for rapid decompensation in patients with SARIs. We aimed to evaluate the impact of acute and emergency care interventions on improving clinical outcomes in patients >10 years old with SARIs in LMICs. Methods: A systematic literature search was performed in PubMed, Global Health, and Global Index Medicus databases to identify peer-reviewed studies containing SARI, LMICs, and emergency care interventions. Studies published prior to November 2020 focusing on patients >10 years old were included. A narrative synthesis was performed due to the heterogeneity of identified articles. Risk of bias was assessed using the Risk of Bias 2 and Risk of Bias In Non-Randomized Studies of Interventions tools. Results: 20 223 studies were screened and 58 met the inclusion criteria. Thirty-four studies focused on coronavirus-2019 (COVID-19), 15 on pneumonia, seven on influenza, one study on severe acute respiratory syndrome, and one on undifferentiated SARI. Few COVID-19 studies found a benefit of the tested intervention on clinical status, mortality, or hospital length-of-stay. Little to no benefit was found for azithromycin, convalescent plasma, or zinc, and potential harm was found for hydroxychloroquine/chloroquine. There was mixed evidence for immunomodulators, traditional Chinese medicine, and corticosteroids among COVID-19 studies, with notable confounding due to a lack of consistency of control group treatments. Neuraminidase inhibitor antivirals for influenza had the highest quality of evidence for shortening symptom duration and decreasing disease severity. Conclusions: We found few interventions for SARIs in LMICs with have high-quality evidence for improving clinical outcomes. None of the included studies evaluated non-pharmacologic interventions or were conducted in low-income countries. Further studies evaluating the impact of antivirals, immunomodulators, corticosteroids, and non-pharmacologic interventions for SARIs in LMICs are urgently needed.

OBJECTIVE: The objective was to identify the most important and impactful peer-reviewed global emergency medicine (GEM) articles published in 2021. The top articles are summarized in brief narratives and accompanied by a comprehensive list of all identified articles that address the topic during the year to serve as a reference for clinicians, researchers, and policy makers. METHODS: A systematic PubMed search was carried out to identify all GEM articles published in 2021. Title and abstract screening was performed by trained reviewers and editors to identify articles in one of three categories based on predefined criteria: disaster and humanitarian response (DHR), emergency care in resource-limited settings (ECRLS), and emergency medicine development (EMD). Included articles were each scored by two reviewers using established rubrics for original (OR) and review (RE) articles. The top 5% of articles overall and the top 5% of articles from each category (DHR, ECRLS, EMD, OR, and RE) were included for narrative summary. RESULTS: The 2021 search identified 44,839 articles, of which 444 articles screened in for scoring, 25% and 22% increases from 2020, respectively. After removal of duplicates, 23 articles were included for narrative summary. ECRLS constituted the largest category (n = 16, 70%), followed by EMD (n = 4, 17%) and DHR (n = 3, 13%). The majority of top articles were OR (n = 14, 61%) compared to RE (n = 9, 39%). CONCLUSIONS: The GEM peer-reviewed literature continued to grow at a fast rate in 2021, reflecting the continued expansion and maturation of this subspecialty of emergency medicine. Few high-quality articles focused on DHR and EMD, suggesting a need for further efforts in those fields. Future efforts should focus on improving the diversity of GEM research and equitable representation.

Objectives: The Interdisciplinary Cardiac Arrest Research Review (ICARE) group was formed in 2018 to conduct an annual search of peer-reviewed literature relevant to cardiac arrest. Now in its third year, the goals of the review are to highlight annual updates in the interdisciplinary world of clinical cardiac arrest research with a focus on clinically relevant and impactful clinical and population-level studies from 2020. Methods: A search of PubMed using keywords related to clinical research in cardiac arrest was conducted. Titles and abstracts were screened for relevance and sorted into 7 categories: Epidemiology & Public Health Initiatives; Prehospital Resuscitation, Technology & Care; In-Hospital Resuscitation & Post-Arrest Care; Prognostication & Outcomes; Pediatrics; Interdisciplinary Guidelines & Reviews; and a new section dedicated to the coronavirus disease 2019 (COVID-19) pandemic. Screened manuscripts underwent standardized scoring of methodological quality and impact on the respective fields by reviewer teams lead by a subject matter expert editor. Articles scoring higher than 99 percentiles by category were selected for full critique. Systematic differences between editors' and reviewers' scores were assessed using Wilcoxon signed-rank test. Results: A total of 3594 articles were identified on initial search; of these, 1026 were scored after screening for relevance and deduplication, and 51 underwent full critique. The leading category was Prehospital Resuscitation, Technology & Care representing 35% (18/51) of fully reviewed articles. Four COVID-19 related articles were included for formal review that was attributed to a relative lack of high-quality data concerning cardiac arrest and COVID-19 specifically by the end of the 2020 calendar year. No significant differences between editor and reviewer scoring were found among review articles (P = 0.697). Among original research articles, section editors scored a median 1 point (interquartile range, 0-3; P < 0.01) less than reviewers. Conclusions: Several clinically relevant studies have added to the evidence base for the management of cardiac arrest patients including methods for prognostication of neurologic outcome following arrest, airway management strategy, timing of coronary intervention, and methods to improve expeditious performance of key components of resuscitation such as chest compressions in adults and children.
RESUMEN
INTRODUCTION: Airway management is a controversial topic in modern Emergency Medical Services (EMS) systems. Among many concerns regarding endotracheal intubation (ETI), unrecognized esophageal intubation and observations of unfavorable neurologic outcomes in some studies raise the question of whether alternative airway techniques should be first-line in EMS airway management protocols. Supraglottic airway devices (SADs) are simpler to use, provide reliable oxygenation and ventilation, and may thus be an alternative first-line airway device for paramedics. In 2019, Alachua County Fire Rescue (ACFR; Alachua, Florida USA) introduced a novel protocol for advanced airway management emphasizing first-line use of a second-generation SAD (i-gel) for patients requiring medication-facilitated airway management (referred to as "rapid sequence airway" [RSA] protocol). STUDY OBJECTIVE: This was a one-year quality assurance review of care provided under the RSA protocol looking at compliance and first-pass success rate of first-line SAD use. METHODS: Records were obtained from the agency's electronic medical record (EMR), searching for the use of the RSA protocol, advanced airway devices, or either ketamine or rocuronium. If available, hospital follow-up data regarding patient condition and emergency department (ED) airway exchange were obtained. RESULTS: During the first year, 33 advanced airway attempts were made under the protocol by 23 paramedics. Overall, compliance with the airway device sequence as specified in the protocol was 72.7%. When ETI was non-compliantly used as first-line airway device, the first-pass success rate was 44.4% compared to 87.5% with adherence to first-line SAD use. All prehospital SADs were exchanged in the ED in a delayed fashion and almost exclusively per physician preference alone. In no case was the SAD exchanged for suspected dislodgement evidenced by lack of capnography. CONCLUSION: First-line use of a SAD was associated with a high first-pass attempt success rate in a real-life cohort of prehospital advanced airway encounters. No SAD required emergent exchange upon hospital arrival.

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.

We sought to compare the costs of a nighttime pediatric telemedicine and medication delivery service per disability-adjusted life year (DALY) averted to the costs of current hospital emergency care per DALY averted from a societal perspective. We studied a nighttime pediatric telemedicine and medication delivery service and hospital emergency care in a semi-urban and rural region of Haiti. Costs of the two services were enumerated to represent the financial investments of both providers and patients. DALYs averted were calculated to represent the "years lives lost" and "years lost to disability" from diarrheal, respiratory, and skin (bacterial and scabies etiologies) disease among children from 0 to 9 years old. The incremental cost-effectiveness ratio was estimated and compared with the per capita gross domestic product (GDP) of Haiti ($1,177). Cost-effectiveness was defined as an incremental cost-effectiveness less than three times the per capita GDP of Haiti ($3,531). The total costs of the nighttime telemedicine and medication delivery service and hospital emergency care to society were $317,898 per year and $89,392 per year, respectively. The DALYs averted by the service and hospital emergency care were 199.76 and 22.37, respectively. Correspondingly, the incremental cost-effectiveness ratio is estimated at $1,288 signifying the service costs an additional $1,288 to avert one additional DALY. A scaled nighttime pediatric telemedicine and medication delivery service is likely a cost-effective alternative to hospital emergency care for preemergency pediatric conditions in Haiti, and possibly in similar lower-middle-income countries.
RESUMEN
INTRODUCTION: Cardiac arrest remains a common and devastating cause of death and disability worldwide. While targeted temperature management has become standard of care to improve functional neurologic outcome, few pharmacologic interventions have shown similar promise. METHODS/ANALYSIS: This systematic review will focus on prospective human studies from 2015 to 2020 available in PubMed, Web of Science and EMBASE with a primary focus on impact on functional neurologic outcome. Prospective studies that include pharmacologic agents given during or after cardiac arrest will be included. Study selection will be in keeping with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. If sufficient data involving a given agent are available, a meta-analysis will be conducted and compared with current evidence for therapies recommended in international practice guidelines. ETHICS AND DISSEMINATION: Formal ethical approval will not be required as primary data will not be collected. The results will be disseminated through peer-reviewed publication, conference presentation and lay press. PROSPERO REGISTRATION NUMBER: International Prospective Register for Systematic Reviews (CRD42021230216).

BACKGROUND: Diarrheal disease is a leading cause of morbidity and mortality globally, especially in low- and middle-income countries. High-throughput and low-cost approaches to identify etiologic agents are needed to guide public health mitigation. Nanoliter-qPCR (nl-qPCR) is an attractive alternative to more expensive methods yet is nascent in application and without a proof-of-concept among hospitalized patients. METHODS: A census-based study was conducted among diarrheal patients admitted at two government hospitals in rural Bangladesh during a diarrheal outbreak period. DNA was extracted from stool samples and assayed by nl-qPCR for common bacterial, protozoan, and helminth enteropathogens as the primary outcome. RESULTS: A total of 961 patients were enrolled; stool samples were collected from 827 patients. Enteropathogens were detected in 69% of patient samples; More than one enteropathogen was detected in 32%. Enteropathogens most commonly detected were enteroaggregative Escherichia coli (26.0%), Shiga toxin-producing E.coli (18.3%), enterotoxigenic E. coli (15.5% heat stable toxin positive, 2.2% heat labile toxin positive), Shigella spp. (14.8%), and Vibrio cholerae (9.0%). Geospatial analysis revealed that the median number of pathogens per patient and the proportion of cases presenting with severe dehydration were greatest amongst patients residing closest to the study hospitals." CONCLUSIONS: This study demonstrates a proof-of-concept for nl-qPCR as a high-throughput low-cost method for enteropathogen detection among hospitalized patients.
