Introduction. Clinical evaluation of patients with torso trauma is often a diagnostic challenge. Extended focused assessment with sonography for trauma (EFAST) is an emergency ultrasound scan that adds to the evaluation of intrathoracic abdominal and pericardial cavities done in FAST (focused assessment with sonography for trauma). Objective. This study compares EFAST (the index test) with the ...

BACKGROUND Extended focused assessment with sonography for trauma (eFAST) has been shown to have moderate sensitivity for detection of pneumothorax in trauma. Little is known about the location or size of missed pneumothoraces or clinical predictors of pneumothoraces in patients with false-negative eFAST. METHODS This retrospective cross-sectional study includes all patients with multiple blu...

BACKGROUND Thoracic ultrasound (EFAST) has shown promise in inferring the presence of post-traumatic pneumothoraces (PTXs) and may have a particular value in identifying occult pneumothoraces (OPTXs) missed by the AP supine chest radiograph (CXR). However, the diagnostic utility of hand-held US has not been previously evaluated in this role. METHODS Thoracic US examinations were performed dur...

Percutaneous cardiac intervention is an invasive diagnostic and therapeutic technique which carries a significant complication rate. Although the usefulness of EFAST protocol is widely recognised, this paper will attempt to explore a modified approach involving a focused examination on the retroperitoneal (r-EFAST). We have provided examples of 3 cases where r-EFAST was used to detect retroperi...

OBJECTIVE The purpose of this study was to assess the accuracy of sonographic pneumothorax detection by radiology residents as a part of extended focused assessment with sonography for trauma (eFAST). METHODS In a prospective study, a sonographic search for pneumothoraces was performed as part of a standard FAST examination by the on-call resident. Each lung field was scanned at the second to...

We evaluate photoelectron angular anisotropy parameters for the process of sequential two-photon double electron ionization of helium within the lowest-order time-independent perturbation theory. Our results indicate that for photoelectron energies outside the interval Eslow,Efast , where Eslow= −VHe+ and Efast= −VHe, there is a considerable deviation from the dipole angular distribution, thus ...

introduction trauma is the most common cause of death in youngsters. early detection of internal bleeding via imaging in trauma patients is important. the fast-extended method and the extended focused assessment with sonography for trauma (efast) evaluates hemothorax and pneumothorax in addition to abdominopelvic bleedings and tamponade. patients and methods in this cross-sectional study, after...

BACKGROUND The initial management of a trauma patient is a critical and demanding period. The use of extended focused assessment sonography for trauma (eFAST) has become more prevalent in trauma rooms, raising questions about the real "added value" of chest X-rays (CXRs) and pelvic X-rays (PXR), particularly in haemodynamically stable trauma patients. The aim of this study was to evaluate the e...

INTRODUCTION Early identification of pneumothorax is crucial to reduce the mortality in critically injured patients. The objective of our study is to investigate the utility of surgeon performed extended focused assessment with sonography for trauma (EFAST) in the diagnosis of pneumothorax. METHODS We prospectively analysed 204 trauma patients in our level I trauma center over a period of 12 ...

UNLABELLED The concept that ultrasonography could be interesting in the prehospital setting and during the transfer of traumatized patients is not new. Paradoxically, there is a lack of description of routine use of ultrasonography in emergency ambulances. The aim of this study was to compare the feasibility and efficiency of an extended focused assessment sonography for trauma (eFAST) examinat...
