Filter by:Soft-tissue foreign bodies (FB) are very commonly observed in pediatric emergency departments. Some are metallic and can be diagnosed easily via X-ray radiography, whereas others are radiolucent and are hence less easily diagnosed. Not all FB can be removed effectively, even via open surgery and C-arm guidance. This deficiency may potentially be addressed through the ultrasound (US) skills instrument, which is increasingly popular and is convenient for use in the operation room. In the current study, we evaluated the efficiency of FB removal with the assistance of US and methylene blue (MB) staining.
This study is intended to perform a comparative analysis of novice ultrasound users when taught in person versus virtually. This study aims to show that students will not demonstrate a statistical difference in scores learning in in a virtual environment, guided by professionals, when compared to students learning ultrasound in a traditional, in-person format. Utilizing a Butterfly ultrasound machine, a hand held personal ultrasound device, students wil be guided through a FAST (Focused assessment with sonography in trauma) examination and imaging of the carpal tunnel using modules and instructor aid. The FAST (Focused assessment with sonography in trauma) exam images the heart and abdomen for free flowing blood. The carpal tunnel is a region in the wrist that houses the tendons for finger movement. Participants will be assessed on the ability to identify key regions, anatomical landmarks and confidence in utilize the ultrasound machine.
The aim of this study was to investigate the added value of contrast-enhanced ultrasound (CEUS) for differentiating low risk patients with breast nodules categorized as 4A using the Breast Imaging Reporting and Data System (BI-RADS).
The purpose of this study is to study the application of CEUS and SMI technology in superficial lymph node lesions (metastasis, lymphoma, inflammation, etc.), and to provide some diagnostic ideas for non-invasive diagnosis of lymph node lesions.
The purpose of this study is to evaluate reliability of Point-of-Care ultrasound evaluation performed by general practitioners.
Background and Aim: Pulmonary aspiration of gastric content in the perioperative period is rare, but it is an important cause of morbidity and mortality that anesthetists never want to encounter. Due to reasons such as emergency surgical procedures, communication problems with pediatric patients or their parents, impaired cognitive function, obesity, diabetes mellitus, chronic liver and kidney diseases, it is observed that there is sometimes inconsistency between the periods defined in the preoperative fasting guidelines in pediatric patients and the state of gastric content and volume encountered in clinical practice. There is a lack of data on children on this issue. In this study, primary we aimed to evaluate the incidence of empty and full stomach in pediatric patients who underwent elective and emergency surgery in our routine anesthesia practice. Also we want to determine the relationship between fasting time and qualitative assessment of gastric content. Secondary this study sought to examine whether correlation between gastric ultrasound finding and fasting time, and also to determine relationship with the current comorbidities. Design: This is a prospective, single blinded, observational study. The minimum sample size required to determine the prevalence of full stomach, 0.05, within the limits of ± 0.025 with 0.95 confidence, was calculated as 292. When calculating with the proposed equation of n = 100 + 50i to determine the factors affecting by logistic regression (here i is the number of variables in the model), the minimum number of samples required for logistic regression analysis was calculated as 300 in case of 4 independent variables in the model. n=100+50*4= 300 Methods: Pediatric patients younger than 18 yr old who are to undergo elective and emergency surgery under general anaesthesia at our hospital are enrolled in this prospective observational study between April and December 2021. Preoperative ultrasound examination of the gastric antrum are performed by one anesthesiologist who has been instructed and supervised by an experienced pediatric radiologist and who is blind to the patient's history. Ultrasonographic measurement of the gastric antral cross-sectional area (CSA) are performed in supine position and right lateral decubitus position (RLD). The gastric antrum is imaged in a sagittal plane, between the left lobe of the liver and the pancreas, at the level of the aorta, as previously described [1]. This examination allowed qualitative assessment of gastric contents according to the three-point grading scale previously described by Perlas and colleagues[2]. Grade 0 was defined by the absence of appearance of any content in a flat antrum in both the supine and the RLD positions. Grade 1 was defined by the appearance of any gastric content in the RLD position only, and Grade 2 was defined by the appearance of any content in both the RLD and the supine positions. The antral cross-sectional area is also calculated in both position, by measuring the longitudinal diameter (D1) and the anteroposterior diameter (D2) of the antrum, from serosa to serosa using this formula [3] Antral area= (π x D1 X D2) / 4. Patients' characteristic data ( age, gender, weight, height, BMI and ASA physical status classification), fasting duration, type of elective and emergency surgery, chronic disease and complications (regurgitation, pulmonary aspiration, etc.) that may develop during the peroperative period are recorded.
Background: Point-of-care ultrasound (POCUS) has been suggested as a useful tool in out-of-hospital cardiac arrest (OHCA) for diagnosis and treatment of reversible causes. However, in prehospital emergency medicine performing ultrasound and the translation of the findings can be challenging. As new prehospital ultrasound devices offer the possibility for remote supervision, the impact of tele-supervision on the performance of POCUS during OHCA is unclear. Aims: This prospective observational study aims to evaluate if POCUS with tele-supervision can be performed during CPR without any additional hands-off periods longer than 5 seconds. Methods: In total 30 patients with OHCA, where POCUS is considered, will be included in this study.
The aim of this prospective randomized trial is to compare the efficacy ultrasound guided thoracolumbar interfascial plane block versus bilateral ultrasound guided erector spinae plane block for post-operative pain management after lumbar laminectomy
We hypothesize that recovered COVID-19 patients suffer long term cardiovascular and pulmonary complications, which can be detected by point of care ultrasound. The goal is to comprehensively delineate the long term cardiovascular and pulmonary ultrasound findings in recovered COVID-19 patients, identify risks factors for prolonged heart/lung injury, evaluate long term effects of applied treatment, and assess late medication/vaccine side effects in COVID-19 patients.
According to the hypothesis of this study presented, the effects of smoking on the fetus can be determined by the liver circulation and hepatic metabolism. The basic assumption of this project is; Compensatory and pathological findings can be seen in the fetal liver circulation in babies of mothers who smoke and the findings can be valuable in predicting the direction of fetal development (growth retardation or normal development). In this study, the flow and shunt amounts in the fetal hepatic vessels in normal and smoking pregnant women will be calculated with the help of Doppler US.
