The study evaluates the knowledge and attitude about Focused Assessment with Sonography in Trauma examination among medical students and medical staff in Poland.
We aimed to verify the potencial role of bedside lung ultrasound findings of critically ill patients candidates to liberation from mechanical ventilation in predicting weaning outcomes. The analysis will be taken in two times: immediately before and at the and spontaneous breathing trial.
Previous studies have demonstrated that an experienced ultrasound operator is able to efficiently perform radial arterial puncture on patients where an initial operator failed to puncture arteries via simple palpation. The objective of this study is to compare "difficult-to-puncture" patients randomized into two groups: one group where ultrasound is used to aid artery localisation, and one group where only palpation is used.
This study will determine the efficacy of a teaching program incorporating hybrid simulation in training practicing anesthesiologists on ultrasound (US)-guided continuous peripheral nerve block (CPNB). This study will also examine the extent of practice change following participation in a regional anesthesia teaching program incorporating hybrid simulation. In addition, this study will assess remaining obstacles to incorporating the use of US-guided perineural catheters through identifying potential future interventions and "tool-kits" for setting up perineural catheter programs.
To evaluate the predictive value of clinical, functional (HAQ), laboratory and US variables in relation to disease activity and radiographic outcome in patients with RA who start treatment with Remicade at 24 weeks.
Patients with spondylarthritis (SpA) (including ankylosing spondylitis, psoriatic arthritis, arthritis as part of inflammatory bowel disease and reactive arthritis) have axial involvement (the spine) as well as peripheral inflammation in joints and entheses (where the tendons and ligaments are anchored to the bone). Patients with high disease activity of SpA may need biological treatment (anti-TNF alpha), which are very expensive medications. Thus it is necessary to have a sensitive method for assessing the response to treatment. Ultrasonography (US) is a validated and reliable method for assessing disease activity in joints and tendons, and may be used to follow the treatment response. The present study will include patients with SpA starting on anti-TNF alpha treatment (as first biologic medication or when switching to a new biologic treatment). The study is an extension of the ongoing NORDMARD study (Norwegian longitudinal observational study of arthritic patients starting disease-modifying treatment). The patients will be examined by use of US of 38 joints and 14 entheses at baseline and after 3, 6 and 12 months. The objectives are to explore US as a method to assess peripheral inflammatory activity for evaluation of response to medication as well as to compare the US pathology with clinical and laboratory findings.
The investigators aim to determine if ultrasound guidance results in improved technique when drawing blood via a radial artery puncture.
Retrospective comparison of complex cystic renal lesions which are found with computed tomography (CT) and were controlled with contrast enhanced ultrasound (CEUS).
Currently available investigating modalities like CT scans, MRI etc although have a high accuracy in staging of gastrointestinal(GI) tract malignancies, are not correct in all cases . The aim of this study is to assess the role of intraoperative ultrasound as a modality to increase the staging accuracy of GI tract malignancies
