Filter by:This is a prospective cohort study that describes focused lung ultrasound (FLUS) findings in patients presenting with symptoms of an acute lower respiratory tract infection (LRTI) in general practice in Denmark. Ten general practitioners (GPs) will perform FLUS in addition to their usual care of adults presenting with symptoms of an acute LRTI where the GP suspects a community-acquired pneumonia (CAP). Eligible patients will consecutively be invited to participate during a two months' study period until each GP has included a total of ten patients. The GPs will register information about patients including age, gender, symptoms, clinical findings, results of any point-of-care test performed, if antibiotic treatment was prescribed and they will register information on FLUS performance and findings.
The first case of COVID-19 was identified on December 19 and the world is actually experiencing a pandemic. The surgical procedure in patients with SARS-CoV-2 infection involves the exposure of other patients and the group of health workers who face the care of the patient. Thus, screening with lung ultrasound is an alternative to identify patients with an established or suspected infection that requires urgent surgery. Therefore, the aim of this study is to determinate the operational characteristics of lung ultrasound during the screening process for SARS-CoV-2 infection in patients with an indication for urgent surgery.
A major barrier to ultrasonography in general practice (GP) is the time restriction of their medical consultation. We aimed to evaluate the feasibility of lung ultrasonography (LUS) realized by general practitioners (GP's) into their medical consultation. A prospective, observational, multi-centric and open study conducted in 3 different centers by 15 GP in France. Patient receiving LUS were recruited from December 2019 to January 2020. GP's were all novices and received a training course by LUS expert before the study. Eight-points LUS exam was recorded, timed, and interpreted by GP's. Among the 111 LUS performed, 110 LUS were interpreted. Time duration was 4 (3-5) min with 13% of LUS superior to 5 minutes. There was no significant difference in time duration after stratification by age. Patients were mainly satisfied after receiving LUS, and 80% of patients had a better understanding about their disease due to US realization. In this first prospective, and multicenter study, involving patients consulting in General Practice, we found that LUS seems to be feasible by GP's in a medical consultation. We showed that LUS can be performed fast enough for a GP consultation, and easy to learn. These findings will need to be valided in a randomized and controlled study.
Objective: To determine the effectiveness of bilateral and simultaneous diaphragm visual biofeedback reeducation by ultrasonography in conjunction with high-intensity inspiratory muscle training versus isolated high-intensity inspiratory muscle training in patients with low back pain. Methods: A single blinded randomized clinical trial will be carried out. A total sample of 96 patients with low back 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 bilateral and simultaneous 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.
Objectives: Although cone‐beam computed tomography (CBCT) is becoming a standard of care in implant therapy, concerns have been raised recently about its limitation in imaging peri-implant tissues due to artifacts. The aim of present study was to demonstrate the complementary role of ultrasound (US), for a comprehensive examination of peri-implant tissues in live humans. Material and Methods: Patients with > 1 implant, a CBCT scan, an US scan, and clinical photographs taken during the open-bone surgery were included. The crestal bone thickness (CBT) and facial bone level (FBL) were measured on both modalities, and direct FBL measurements were also made on clinical images. The correlation plots were made to evaluate the measurement agreements between the 3 methods.
A successful implant surgery primarily relies on a prudent evaluation of oral anatomy and meticulous treatment planning. Additionally, of paramount importance that dictates the types of procedures, material selection and ultimately success of implant surgery is the quality and quantity of the edentulous ridge. Ultrasound imaging (US), another cross-sectional imaging modality, has been extensively used in the medical diagnostics field. The ability of ultrasound to image soft tissue-bone interface makes it particularly promising for studying bone ridge width and crestal bone topography. Therefore, this retrospective human study aimed to compare bone width measurements between US and CBCT. This study also investigated the possible correlation between the crestal bone surface quality imaged by US and CBCT.
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.
Patients with acute achilles tendon rupture will go through an acute ultrasound. Based on the distance between the ends of the tendon the investigators will decide if the patient is going to be treated with or without surgery.
This study is a prospective observational research approved by the Ethics Committee of the Peking Union medical college Hospital. Patients scheduled for elective non-abdominal and non-thoracic surgery among age of 19-65 years and American Society of Anesthesiologists Physical Status Classification(ASA) I or II were inrolled. Diaphragm ultrasonogram was measured pre and post operation. Diaphragm excursion and diaphragm thickening fraction during quiet breathing as well as deep breathing were assessed. Neuromuscular monitor was performed during operation, after proper calibration.
