Filter by:Distal radius fracture is a common injury with a high percentage of surgical treatment. In the last decades, volar plate fixation has been the treatment of choice. However, complication rates range between 6% and 50% according to the different study groups. One of the main complications is due to errors in screw measurement given the particular anatomy of the distal radius. Numerous views in addition to the standard ones have been described in order to increase the specificity and sensitivity in the detection of poorly implanted screws. In the absence of a radiological projection superior to another, we believe that the use of intraoperative ultrasound can provide a non-invasive and quick revision element that avoids scope time for both: the patient and the surgical team.
Spasticity of stroke patient, a very common complication in clinical practice, affects performance of hand function and gait pattern. It also interferes with quality of life of patients severely. Currently first line clinical approach to spasticity consist of physical therapy and pharmacological management. However, there are still some refractory cases that needed local intervention such as Botox injection. So far, we only can use subjective methods to measure muscle tension, such as modified Ashworth scale and Tone Assessment Scale. In our previous study, we found that ultrasound shear wave image could correlate with muscle stiffness caused by poststroke spasticity. With this new method, we aim to establish a more objective method in measuring abnormal poststroke muscle tension before and after treatments and further monitor therapeutic effect. We also include several assessment scales to evaluate the correlation between measured muscle spasm and activity of daily living. We hypothesize that the rheological changes in muscles muscle spasm after Botox injection can be detected by ultrasound shear wave image. Therapeutic effect can also be seen in its effect on daily functions. In this project, we will use shear wave imaging of ultrasound to investigate the elasticity (and hardness) of the biceps brachii and brachialis muscle in stroke patients with unilateral hemiplegia before and after Botox injection. The findings of this project will provide the objective evaluation of muscle spasticity and its correlation with functional status, which will provide new points of view toward treatment of spasticity.
The present study is a prospective, single-center study. A total of 88 patients, who had placed a pancreatic stent for preventing post-ERCP pancreatitis, will be included in the study. Aim of the study is to establish a new algorithm based on a sonographic approach to remove the placed pancreatic stents. Another aim is to compare high-end sonographic devices with devices of medium price scale one's used on the ward. On the day of removal of the pancreatic stent, all patients receive a sonography by an experienced investigator on the ward and by another, uninformed investigator with a high-end device. If a pancreatic stent is visualized in the pancreatic duct, the patient will have an esophagogastroduodenoscopy to remove the pancreatic stent. If sonography cannot find a pancreatic stent in the pancreatic duct an x-ray will be performed as suggested by the European and international guidelines. If the pancreatic stent spontaneously dislocated into the small bowel tract according to x-ray, no further investigation will be performed. If a stent is visulized in situ by x-ray, it will be removed by endoscopyl. Statistical analysis will be done in cooperation with the statistical biomedical institute oft he university hospital in Frankfurt.
Best management of suspected large for gestational age (LGA) fetuses is unclear. In some hospitals women with an LGA fetus by customised growth charts are are offered earlier induction. This study aimed to examine scan accuracy for this group and the outcome with intervention.
To assess the prognostic performance of an early global LUS score with respect to the mortality in ICU and duration of ventilation.
Little is known about the correlation between ultrasound characteristics (conventional, elastography and contrast enhanced ultrasound (CEUS) )and pathological prognostic factors in breast cancer. The aim of this study was to explore the correlation between ultrasound characteristics and pathological prognostic factors using radiomics.
The purpose of this study is to assess validity of extended duplex ultrasound examination for diagnosis of proximal deep vein thrombosis performed by general intensive care unit nurses in the critically ill patients.
Anatomically, the infra-glottic area (subglottis) and the cricoid ring are the narrowest part of the larynx. In order to limit the incidence of damage related to mucosal pressure injuries from the presence of an endotracheal tube (ETT), the cuff of the ETT should lie below the cricoid in children. Previously, no clinical or imaging method has been used in real time at the bedside to determine the exact location of the ETT cuff after endotracheal intubation. Point-of-care ultrasound (POCUS) may provide an option for a safe and rapid means of visualizing the cuff of the ETT and its relationship to the cricoid ring in real-time thereby allowing ideal ETT positioning.
The investigators aimed to compare the block characteristics of the single operator "jedi grip" technique and the conventional double operator technique.
Cannot-intubate cannot-ventilate situations in healthy children are uncommon but are often associated with poor outcome. We studied the learning curves of inexperienced trainees for identifying cricothyroid membrane with ultrasound in pediatric patients. After watching an instructional video, 30 trainees performed 5 cricothyroid membrane identification on pediatric patients undergoing general anesthesia. We analysed their learning curves relative to performance time and ultrasound anatomy of cricothyroid membrane and relative structures.
