A national lockdown has a moderate advantage in saving lives with tremendous costs and possible overwhelming economic effects. These findings should assist decision makers dealing with additional waves of this pandemic.This case highlights the novel use of endotracheal tubes to maintain patency of simple thoracostomies (STs) performed to relieve a tension pneumothorax after failed needle thoracostomy (NT). Treatment of a tension pneumothorax in the prehospital setting is typically performed using NT because of the minimal equipment required and rapid application. However, the variable efficacy of NT has led to a rise in the use of ST as an alternative procedure to treat a tension pneumothorax. A potential complication of ST is the occlusion of the thoracostomy site, which, left unresolved, may lead to the reoccurrence of tension physiology. In a resource-rich setting, such as in a hospital, the ST would be followed by tube thoracostomy to ensure patency. Unfortunately, this may not be feasible in prehospital environments where constraints exist because of time, equipment, and personnel. A review of the literature surrounding prehospital ST reveals previous reports of endotracheal tubes being used to maintain patency temporarily. However, no cases documenting the successful use of this novel procedure in an air medical setting were found at the time of writing. learn more This case documents the successful use of this novel procedure during the treatment of a polytraumatized adult female resulting from a motorcycle crash.A 42-year-old man with coronavirus disease 2019 pneumonia was admitted to a small town hospital that did not have intensive care unit (ICU)-level resources available. Twelve hours later, the patient suddenly became agitated, and an extensive anterolateral ST-elevation myocardial infarction was detected by 12-lead electrocardiography and supported by a rise in serum cardiac enzymes. Low blood oxygen saturation (59%) and cardiac ejection fraction (ejection fraction = 20%) reflected criticality that could potentially require a catheterization laboratory, coronary artery bypass graft surgery, and ICU-level resources. After the coordination of physicians with the nearest equipped hospital and air medical crew, a Mil Mi-17 medical helicopter unit was dispatched. About 20 minutes before reaching the destination hospital, his clinical condition declined; his heart was 50 beats/min, his blood pressure was 75/40 mm Hg, and he had jugular vein distention. Muffled heart sounds, decreased electrocardiographic voltage, and the accumulation of pericardial effusion on a bedside ultrasound indicated cardiac tamponade. The air medical crew resuscitated the patient through the interventions of intubation, mechanical ventilation, administration of intravenous fluids, and initiation of an epinephrine infusion. Ultrasound-guided pericardiocentesis was performed in the helicopter, which kept him alive until pericardotomy could be performed at the destination hospital. Unfortunately, after pericardiotomy and coronary artery bypass graft surgery, the patient died 7 days later in the ICU due to severe cardiopulmonary failure.
Point-of care-ultrasound (PoCUS) is useful in evaluating unstable emergency department patients. The portability of this technology increases its potential use in prehospital settings, including helicopter emergency medical services (HEMS) programs. Identifying useful applications may support implementing a PoCUS program that develops sonography skills for prehospital providers. The aim of this study was to determine the HEMS patient population that would benefit from prehospital PoCUS for hypotension and how commonly the extended focused assessment with sonography in trauma (E-FAST) for trauma patients or the rapid ultrasound in shock (RUSH) for medical patients could be used by HEMS.

A retrospective chart review was performed over a 1-year period of adult patients transported by a midwestern HEMS system. Charts were reviewed for episodes of hypotension.

The chart review included 216 charts, of which 3 were excluded. Of the 213 cases, 100 were trauma patients, and 113 were medical patients. Of the trauma patients, 51% experienced hypotension, as did 73 of 113 medical patients.

Fifty percent of HEMS patients may benefit from PoCUS to evaluate for hypotension in flight.

Limited information exists regarding the response of helicopter emergency medical services (HEMS) programs to patients with known or suspected coronavirus disease 2019 (COVID-19). The purpose of this study was to determine changes in flight operations during the early stages of the pandemic.

A survey of the American College of Emergency Physicians Air Medical Section was conducted between May 13, 2020, and August 1, 2020. COVID-19 prevalence was defined as high versus low based on cases > 2,500 or ≤ 2,500.

Of the 48 respondents, the majority (89.6%) reported that their patient guidelines had changed because of COVID-19; 89.6% of programs reported transporting COVID-19-positive patients, whereas 91.5% reported transporting persons under investigation. The majority of respondents reported additional training in COVID-19 airway management (79.2%) and personal protective equipment use (93.6%). Permitted aerosol-generating procedures included bilevel positive airway pressure (40.4%) and high-flow nasal oxygen (66.0%). No difference in guideline changes, positive COVID-19/persons under investigation transport restrictions, or permitted aerosol-generating procedures were noted between high- and low-prevalence settings.

COVID-19 has resulted in changes to HEMS guidelines regardless of local disease prevalence. The pandemic has persisted sufficiently long that data regarding the effectiveness of guideline changes should be analyzed. In the absence of definitive data, national best practices should be developed to guide COVID-19 HEMS transport.
