Filter by:For the emergency physicians and critical care specialists, how to quickly recognize shock from diverse clinical features and immediately treat shock patients to prevent progression to irreversible organ dysfunction from initially reversible shock condition are important issues and challenges. In recent years, ultrasonography had been extensively used in clinical practice recently, and well-trained medical staffs can quickly and easily apply ultrasound to evaluate, examine, diagnose, and even treat the patients. The clinical application of point-of-care ultrasound can help the first-line physicians rapidly evaluate and diagnose the main symptoms and signs of the patients at bedside, and further initially stabilize and appropriately treat the patients subsequently. The aim of this program is to prospectively collection of the findings of point-of-care ultrasonography in shock patients at emergency room in NTUH. The clinical manifestations, and followed up the examinations, treatments, and prognosis will also be collected. The effect of bedside ultrasound on differential diagnosis and treatment of shock patients will be analyzed. The results of the current study can provide the base for further clinical trials and set up of shock team.
In COVID-19 patients hospitalized in the intensive care unit due to respiratory failure, lung ultrasonography will be tried to be given an appropriate position that will effectively use lung capacity and its effect on oxygenation will be investigated.
Effective analgesia after total abdominal hysterectomy is important for faster recovery and preventing complications which depend to pain. A multimodal and preventive approach is preferred to ensure adequate analgesia and to avoid side effects due to high doses of analgesics. The hypothesis was that the Quadratus Lumborum block (application of local anesthetics to the side of the abdomen) would be superior to Transversus Abdominis Plane block (application of local anesthetics in front of the abdomen) for analgesia before abdominal incision in total abdominal hysterectomy. The primary goal of the study was to evaluate the feasibility of ultrasound-guided Transversus Abdominis Plane block and Quadratus Lumborum block. The secondary goal was to evaluate postoperative adverse effects and patient satisfaction.
Introduction: Clinical ultrasound is a technique that increases diagnostic capacity and facilitates clinical decision making. The objective is to develop and validate an ultrasound training methodology oriented to the clinical practice of the family doctor. Methods: quasi-experimental study, with before / after design, with a control group and one year of follow-up. 20 family doctors working in primary care Health Centers and with a list of patients over 800 will be included and a control group of similar characteristics will be selected, in terms of age, gender and patient list. A structured training process oriented to the clinical practice of the family physician, Primary Care Clinical Ultrasound Classroom (AECAP) will be carried out, and the improvement of knowledge and skills will be evaluated, as well as the improvement of quality of care based on clinical indicators. Discussion: The Family Physician is in a privileged situation to increase the performance of the ultrasound in frequent clinical situations and allows a reduction of the attention times. Investigators hope that the results obtained in this study demonstrate the effectiveness of the structured training method (AECAP) and support the generalization of ultrasound in Primary Health Care.
448kilohertz capacitive resistive monopolar radiofrequency is a novel technique in physiotherapy and its usefulness and clinical relevance is still to be investigated at both clinical practice and also in performance. Current studies show promising results in different musculoskeletal disorders, however there no studies in the assessment of quality soft tissue in sporty population after the used of this technique.
Background: Ultrasound has become clinical skill widely used in most medical disciplines. Institutions are changing their curricula to implementing basic ultrasound knowledge, often supplementing traditional teaching with 'near-peer' tutoring through classes held by advanced peers. Near-peer tutoring has been found to be both effective and cost-effective. In Switzerland the most popular course in postgraduate training is a resource-intensive 21-hour basic course for abdominal ultrasound. However, this is expensive, and may not be the best way to impart these skills to undergraduates, who need training more adapted to their needs. Therefore a 21-hour blended-learning ultrasound course, comprising 5 hours of e-learning and 16 hours of near-peer tutoring has been developped. Students and their near-peer tutors autonomously organize individual practical teaching sessions within a 16 weeks time period. Methods: Medical students from second to fourth year at the Universities of Bern, Fribourg and Zurich will be included. Stratified by study site, students will be randomized to one of the two interventions. The blended-learning group will receive e-learning and near-peer tutoring over 16 weeks; the other group will receive 21 hours of teaching, from ultrasound experts, in a 2.5-day course. All participants will undergo a six-station OSCE directly after the course and 6 months later. Students will fill out online questionnaires at baseline, directly after the course and 6 months later. The mean scores of both groups will be compared at six months after the end of both courses. Secondary outcome measures will be students' ultrasound skills immediately after the courses, student satisfaction, multivariate regression exploring factors that affect outcome at 6 months and exploratory subgroup analysis. Discussion: This study is designed to compare the current way of ultrasound education in Switzerland with a new blended learning course. It aims to determine whether the blended learning course is as good as, or better than the existing 21-hour standard course. If this is found to be the case, blended learning could help to expand capacity to offer such courses to undergraduate medical students. It would eventually allow undergraduate Swiss medical students to acquire ultrasound skills before starting their residencies. This study also aims at improving the understanding of how to achieve effective student-centred learning supported by near-peer tutoring.
Objective: To determine the effectiveness of diaphragm visual biofeedback reeducation by ultrasonography in conjunction with high-intensity inspiratory muscle training versus isolated high-intensity inspiratory muscle training in athletes with lumbo-pelvic pain. Methods: A single blinded randomized clinical trial will be carried out. A total sample of 80 athletes with lumbo-pelvic pain will be recruited and randomized into 2 groups: one group will be treated by isolated high-intensity inspiratory muscle training during 8 weeks, and another group will be treated with diaphragm visual biofeedback reeducation by ultrasonography during 6 weeks in conjunction with high-intensity inspiratory muscle training during 8 weeks. Outcome measurements will be diaphragm muscle thickness evaluated by ultrasonography (main outcome measurement), pain intensity, pressure pain threshold, disability, quality of life and respiratory parameters by spirometry, which will be assessed before and after intervention.
Fluid overload is associated with adverse outcomes in patients with severe acute kidney injury. It remains unclear if fluid overload is merely a marker of disease severity or if organ congestion is a mediator of complications. Point-of-care ultrasound could be a modality used to assess organ congestion and its clinical implications. The objective of this study is to determine whether ultrasound markers of organ congestion are associated with major adverse kidney events in critically ill patients with severe acute kidney injury.
This prospective observational study aimed to obtain ultrasound images for ultrasound-assisted paramedian spinal anesthesia and identify the differences according to sidedness of approach, position and age.
Prospective clinical study ：observing the correlation between endometrial elasticity score, endometrial blood flow index (PI, RI, S/D, endometrial thickness, morphology) and clinical pregnancy rate. In order to find a non-invasive, convenient and comprehensive evaluation method of evaluating the endometrial receptivity, and to provide effective means for the frozen embryo transplantation patients to improving pregnancy outcome.
