Without the requirement of line-of-sight, electromagnetic (EM) tracking is increasingly studied and used in clinical applications. We designed experiments to evaluate a commercial EM tracking system in three situations: using the EM sensor by itself; fixing the sensor onto the handle of a stereoscopic (i.e., 3D) laparoscope; and placing the sensor on the outside surface of the head of a laparos...

Ultrasound has been used to observe lung aeration and fluid clearance during the neonatal transition period, but there is no consensus regarding optimal timing of ultrasound. We aimed monitor trend serial ultrasound score (LUS) extended LUS (eLUS) throughout period (≤1, 2, 4, 8, 24, 48 h after birth), assess any correlation clinical presentation (using Silverman Andersen Respiratory Severity Sc...

Abstract Funding Acknowledgements Type of funding sources: None. Background Aortic stenosis (AS) is a progressive disease and once symptomatic heart failure (HF) develops associated with poor prognosis. The degree the pathophysiological structural changes in AS are survival. Pulmonary congestion an almost universal finding patients HF. Lung ultrasound (LUS) evaluation B-lines has been proposed ...

BACKGROUND Atelectasis is a common finding in mechanically ventilated children with healthy lungs. This lung collapse cannot be overcome using standard levels of positive end-expiratory pressure (PEEP) and thus for only individualized lung recruitment maneuvers lead to satisfactory therapeutic results. In this short communication, we demonstrate by lung ultrasound images (LUS) the effect of a p...

OBJECTIVES/HYPOTHESIS Vocal fold motion impairment (VFMI) is a known sequela of cardiovascular surgery. The gold standard for the evaluation of vocal fold movement is flexible nasolaryngoscopy (FNL). Although safe, FNL does cause measurable physiologic changes. Noxious stimuli in cardiovascular intensive care unit (CVICU) neonates may cause imbalance between the pulmonary and systemic circulati...

BACKGROUND The prognostic value of extravascular lung water indices (EVLWI) has been widely investigated, which is determined by lung ultrasound B-lines. However, the clinical value of lung ultrasound B-lines for determining prognosis/intensive care unit (ICU) outcomes in patients with acute respiratory distress syndrome (ARDS) has been rarely reported. METHODS Twenty-one ARDS patients admitt...

Idiopathic pulmonary fibrosis (IPF) is the severest form of idiopathic interstitial pneumonia, with a median survival time estimated at 2-5 years from the time of diagnosis. It occurs mainly in elderly adults, suggesting a strong link between the fibrosis process and aging. Although chest high-resolution computed tomography (HRCT) is currently the method of choice in IPF assessment, diagnostic ...

Objectives: This study focused on evaluating the value of transvaginal 3D ultrasound for the diagnosis and prognostic assessment of post-cesarean section uterine diverticulum. Materials and Methods: We retrospectively analyzed the data from 32 patients with post-cesarean section uterine diverticulum over three recent years. In all patients, transvaginal 3D ultrasound was used to measure the siz...
