Bedside POCUS during ward emergencies is associated with improved diagnosis and outcome: an observational prospective controlled study

摘要

POCUS-guided managements: ultrasound protocol. (a) Circulatory failure protocol. Use of the HHUD (Vscan Dual Probe extend™, General Electric Healthcare): Cardiac assessment with sector transducer to access the LV and RV function: (1) subcostal view or (2) apical four-chamber view–Pulmonary assessment with the linear transducer: (1) anterior chest based between the clavicle to the diaphragm and the mid-axillary line (2) pleural bases. Abbreviations: EFLV, ejection fraction left ventricular; IVC, inferior vena cave; LV, left ventricular; RA, right auricle; RV, right function. (b) Respiratory failure protocol. Use of the HHUD (Vscan Dual Probe extend™, General Electric Healthcare): Pulmonary assessment with the linear transducer: (1) anterior chest based between the clavicule to the diaphragm and the mid-axillary line (2) pleural bases. Cardiac assessment with the sector transducer to assess the right ventricular function: (1) subcostal view or n apical four-chamber view. Deep venous assessment with the linear transducer to identify thrombosis: femoral and popliteal veins. The visual EFLV helps to differentiate between cardiogenic edema (EFLV altered) and acute interstitial lung disease (non-cardiogenic edema) (EFLV not altered). Abbreviations: EFLV, ejection fraction left ventricular; COPD, chronic obstructive pulmonary disease
