Focused Cardiac Ultrasound Using a Pocket-Size Device in the Emergency Room

چکیده
Background: Cardiovascular urgencies are frequent reasons for seeking medical care. Prompt and accurate medical diagnosis is critical to reduce the morbidity and mortality of these conditions. Objective: To evaluate the use of a pocket-size echocardiography in addition to clinical history and physical exam in a tertiary medical emergency care. Methods: One hundred adult patients without known cardiac or lung diseases who sought emergency care with cardiac complaints were included. Patients with ischemic changes in the electrocardiography or fever were excluded. A focused echocardiography with GE Vscan equipment was performed after the initial evaluation in the emergency room. Cardiac chambers dimensions, left and right ventricular systolic function, intracardiac flows with color, pericardium, and aorta were evaluated. Results: The mean age was 61 ± 17 years old. The patient complaint was chest pain in 51 patients, dyspnea in 32 patients, arrhythmia to evaluate the left ventricular function in ten patients, hypotension/dizziness in five patients and edema in one patient. In 28 patients, the focused echocardiography allowed to confirm the initial diagnosis: 19 patients with heart failure, five with acute coronary syndrome, two with pulmonary embolism and two patients with cardiac tamponade. In 17 patients, the echocardiography changed the diagnosis: ten with suspicious of heart failure, two with pulmonary embolism suspicious, two with hypotension without cause, one suspicious of acute coronary syndrome, one of cardiac tamponade and one of aortic dissection. Conclusion: The focused echocardiography with pocket-size equipment in the emergency care may allow a prompt diagnosis and, consequently, an earlier initiation of the therapy.Fundamento: As urgências cardiovasculares são causas importantes de procura por atendimento médico, sendo fundamentais a rapidez e a precisão no diagnóstico para diminuir sua morbimortalidade. Objetivo: Avaliar o uso da ecocardiografia direcionada como complemento diagnóstico ao exame físico em um serviço terciário de emergências clínicas. Métodos: Foram incluídos cem pacientes adultos sem doenças cardíacas ou pulmonares conhecidas que procuraram atendimento de urgência com queixas cardiológicas. Foram excluídos pacientes com alterações isquêmicas no eletrocardiograma ou febre. A ecocardiografia direcionada foi realizada logo após a avaliação inicial do paciente na sala de emergência, com aparelho ultraportátil GE Vscan, avaliando subjetivamente: dimensões das cavidades, função sistólica ventricular, fluxos intracardíacos pelo mapeamento de fluxo em cores, pericárdio e aorta. Resultados: A idade média dos pacientes foi 61 ± 17 anos. O quadro clínico inicial foi dor torácica (52 pacientes), dispneia (32 pacientes), arritmia/avaliação da função ventricular (dez pacientes), hipotensão/tontura (cinco pacientes) e edema periférico (um paciente). Em 28 pacientes a ecocardiografia direcionada confirmou a hipótese diagnóstica inicial: 19 pacientes com insuficiência cardíaca, cinco com síndrome coronariana aguda, dois com tromboembolismo pulmonar e dois com tamponamento cardíaco. Em 17 pacientes, a ecocardiografia direcionada alterou o diagnóstico, afastando a hipótese clínica inicial em dez casos com suspeita de insuficiência cardíaca, dois com suspeita de tromboembolismo pulmonar, dois com hipotensão a esclarecer, e em cada um dos três restantes com suspeitas de síndrome coronariana aguda, tamponamento cardíaco e dissecção de aorta. Conclusão: A ecocardiografia direcionada ultraportátil em serviço de emergências clínicas pode definir rapidamente o diagnóstico e, com isso, é possível iniciar mais precocemente o tratamento adequado.

Evaluation of a new pocket echoscopic device for focused cardiac ultrasonography in an emergency setting
INTRODUCTION In the emergency setting, focused cardiac ultrasound has become a fundamental tool for diagnostic, initial emergency treatment and triage decisions. A new ultra-miniaturized pocket ultrasound device (PUD) may be suited to this specific setting. Therefore, we aimed to compare the diagnostic ability of an ultra-miniaturized ultrasound device (Vscan™, GE Healthcare, Wauwatosa, WI) and...

BACKGROUND Although pocket-sized, simplified ultrasound devices have emerged to enable subjective point-of-care assessment, few data on their cardiac application exist. We sought to examine the image quality and the accuracy of subjective diagnosis of video loops obtained from a pocket-sized ultrasound device for 2 significant cardiac abnormalities, left ventricular systolic dysfunction and lef...
متن کاملPocket ultrasound devices for focused echocardiography
Pocket ultrasound devices have recently been developed and may be particularly useful for emergency assessment. These devices can be stored in a pocket but share only some technical features with conventional echocardiographic machines. Two-dimensional imaging and color flow mode are available, with possible adjustments of global gain and depth, but Doppler features are lacking. These devices a...
