Point-of-care Ultrasound in Morbidity and Mortality Cases in Emergency Medicine: Who Benefits the Most?

POCUS was felt to have the potential to reduce or prevent M&M in 45% of cases in which it was not used. Cardiac and Lung POCUS were among the most useful applications, especially in patients with cardiopulmonary complaints and in those with abnormal vital signs.

Ultrasound outperforms XR for neonatal pneumothorax

Lung ultrasound outperformed CXR for detecting neonatal pneumothorax in a recent review of 500+ newborns. Ultrasound achieved better sensitivity and specificity and took less time to perform. Based on the findings, the researchers recommended LUS as a first-line modality for diagnosing pneumothorax in this population.

Flattening POCUS learning curve.

A recent pilot trial showed that a short training course dramatically increased the confidence of geriatricians in their ability to use bedside ultrasound, and interpret images.

Obstetrics & Gynecology

Butterfly iQ Deployed in Drive-Through Prenatal Care.

In response to COVID-19, a drive-through prenatal care model was developed in which pregnant women would remain in their cars while being assessed by the health care professional, thus reducing potential patient, health care professional, and staff exposure to COVID-19.

Ultrasound in Medicine & Biology

Recent study shows a statistically significant correlation between portable-scanner findings and COVID-19 disease severity.

A study, published in Ultrasound in Medicine & Biology in September 2020, shows a statistically significant correlation between portable-scanner findings and disease severity, sensitivity, specificity and diagnostic accuracy in detecting mild, moderate and severe lung lesions associated with COVID-19.
