- Deteção precoce de doença metastática através de ecografia de triagemPublication . Vaz, Bruna; Miravent, Sérgio; Gomes, Carla; Gago, Rui; Lobo, Manuel; Almeida, Rui Pedro deA ecografia de triagem é crucial nos serviços de emergência, fornecendo orientação precisa para pacientes em diversas situações clínicas. A ecografia é móvel, produz imagens em tempo real e é isenta de radiação. É uma ferramenta apta para ambientes de meios tecnológicos limitados e ausência de médicos especialistas. O uso da ecografia de triagem entre profissionais de saúde, independentemente do seu nível de especialização em ultrassonografia, nasce da necessidade de responder a dúvidas clínicas concretas na prática quotidiana. Este artigo enfatiza o papel crucial da ecografia de triagem num caso de abdómen agudo. A sua integração com a radiologia convencional melhora significativamente a orientação clínica, facilitando decisões de tratamento e encaminhamentos à especialidade quando necessário. Neste caso específico, foram analisadas imagens de ecografia de triagem, radiografia abdominal e exame tomografia computorizada juntamente com relatórios clínicos para avaliar a orientação clínica dada num serviço de emergência básico periférico. O paciente em causa apresentava sintomas abdominais agudos, revelando suspeita de metástases hepáticas, líquido livre intraperitoneal e sinais de obstrução intestinal no exame de triagem ecográfica. Estes achados foram confirmados por tomografia computorizada no hospital de referência. A ecografia de triagem pode revolucionar a segurança do paciente, economizando tempo ao detetar precocemente patologias, prevenindo sobrelotação nos departamentos de emergência de hospitais centrais de referência. A deteção ultrassonográfica de imagens suspeitas de metástases é comum em ambientes hospitalares onde diversos meios diagnósticos avançados e especialidades médicas estão presentes. A utilização do ultrassom como ferramenta de triagem e orientação clínica de primeira linha em ambientes pré-hospitalares está em consonância com as estratégias médicas contemporâneas, que visam aprimorar a deteção e a intervenção precoces.
- Pre-hospital identification of a giant bladder calculus through screening sonography: A case reportPublication . Miravent, Sergio; Gomes, Carla; Simãozinho, Paula; Vaz, Bruna; Lobo, Manuel; Almeida, Rui Pedro deIntroduction: Screening ultrasound proves to be remarkably beneficial in pre-hospital settings, particularly in geographically remote areas with technological constraints and no medical specialties. Urological pathology has a high frequency of occurrence in the emergency department and is part of the wide range of occurrences that can benefit from this ultrasound screening as a clinical guide for patients. Case Presentation: In this case, a patient experiencing lower abdominal pain and symptoms of renal colic sought assistance at a basic emergency service facility. Utilizing a renal screening ultrasound executed by a sonographer, the clinical team identified images indicative of a significant bladder calculus. Subsequently, the patient was referred to a referral hospital for a comprehensive evaluation by medical specialties. Conclusion: The images obtained in both health units exhibited congruence, indicating that the screening ultrasound, while not intended to replace the specialized orthodox ultrasound executed by a radiologist, served as a crucial tool for diagnostic presumption, providing consistency in clinical decision-making for referring patients. This capability allowed emergency physicians to promptly transfer a patient requiring urgent further investigation to a referral hospital with compelling and substantiated data. This shift in the approach to patient triage in a remote setting could enhance patient safety.
- Renal screening sonography. A comparative study in a Portuguese basic emergency servicePublication . Miravent, Sérgio; Jiménez, Carmen; Barbancho, Narciso; Lobo, Manuel; Figueiredo, Teresa; Gomes, Carla; Ratusneac, Ion; Gonçalves, João Mário; Hasnas, Corina; Almeida, Rui Pedro deIntroduction: This study intends to compare the accuracy and pertinence of sonographic findings obtained by a sonographer in a Basic Emergency Service (BES) with the imaging findings at the Referral Hospital (RH). Methods: Thirty-one patients suspected of having renal pathology underwent initial renal sonography screening with sonographer reporting at the BES and were subsequently referred to the RH for additional imaging examinations. The results of both examinations were compared to verify whether the findings from the BES were confirmed by the radiologist in the RH and to ensure that the patient referrals from BES to RH were appropriate. Results: In our sample, most patients (80%) exhibited varying degrees of pyelocaliceal distension, with nearly half (48%) presenting obstructions. A strong association between the sonographic findings in the BES and the RH was found in the variables “Dilatation of pyelocaliceal system” (V=0.895; p=0.000), “Simple cystic formation” (V=0.878; p=0.000), respectively. There was a statistically significant correlation between BES and RH findings, indicating a strong association between these two variables respectively (k=0.890; p=0.000) and (k=0.870; p=0.000). In this research, an achieved sensitivity of 96% and a specificity of 85% were demonstrated in the identification of pyelocaliceal dilatation. Conclusion: Renal sonographer reporting screening successfully detected abnormalities in the urinary system of patients suspected of having renal colic. The sonographic data obtained at the BES demonstrated a strong correlation with the additional imaging findings from the RH in Portugal. These results suggest that Radiographers/Sonographers can have an important role in the preliminary assessment of urgent renal pathology in remote areas, contributing to a correct referral and early treatment.
