Filter by: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.
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.
This will be a single center, methodological study in healthy male subjects to evaluate the intra-period, inter-period and inter-observer reproducibility of flow measurements in the superior mesenteric artery, using Doppler Ultrasound.
Endovaginal ultrasound is currently the gold standard to diagnose a shorted cervical length and, by extension, assess the risk of preterm labor. The major inconvenient is that this is an invasive method of diagnosis that tends to be poorly accepted by some patients. This study aims to evaluate the accuracy of a noninvasive transperineal ultrasound cervical measurement in comparison to the endovaginal technic in 2nd and 3nd trimester pregnant women where a cervical ultrasound is indicated.
The current COVID-19 pandemic is providing healthcare organizations with considerable challenges and opportunities for rapid cycle improvement efforts, in diagnostic and patient management arenas. Healthcare providers are tasked with limiting the use of personal protective equipment while minimizing unnecessary exposures to the virus. Results from real-time PCR tests to detect active COVID-19 infections may not be available in a timely fashion during emergent trauma assessments. Since the start of the COVID-19 pandemic, a rapidly expanding body of literature has identified a pattern of imaged lung abnormalities with CT and ultrasound (US) characteristic of an active viral infection. US evaluation provides a reliable, portable, and reproducible way of evaluating acute patients in a real time setting. During initial trauma evaluations, patients may also receive adjunct imaging modalities like the Focused Assessment with Sonography in Trauma (FAST) exam designed to discover life threatening findings that may require urgent interventions. We therefore propose a study expanding on the current FAST adjunct evaluation in the trauma bay that may include lung parenchyma imaging at the initial assessment to help stratify patients into low or high-risk groups for active COVID-19 infections. We believe the use of point of care US in the initial assessment of the trauma patient may help identify potentially infected individuals and aid ED providers to best directing subsequent laboratory and imaging evaluations for these patients, while further directing the necessary protective measures for additional team members involved in the care of the injured patient.
We aimed to investigate the effect of kinesiotaping on pain, functionality and ultrasound parameters in patients with shoulder impingement syndrome (SIS).
Recurrent fluid surrounding the lungs is associated with poor quality of life, the main symptom being dyspnea. These patients are in need of recurrent removal of the fluid using drainage. The mechanism causing dyspnea is not fully understood. By using ultrasound to evaluate the movement of the diaphragm before and after removal of fluid and the patients symptoms before removal of fluid and until next removal the research group aims to clarify the temporal development in symptoms and the role of the diaphragm. The researchers will also evaluate the ability of the pulmonologist and patient to predict when the patient will need the next removal of fluid in patients with recurrent unilateral pleural effusion.
