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.
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 study is to compare the analgesic efficacy of ultrasound guided continuous SAP block and ultrasound guided continuous TPVB in patients with multiple traumatic rib fractures.
Intrathecal administration of Nusinersen, an antisense oligonucleotide capable of increasing Survival Motor Neuron protein production, has been tested in Spinal Muscular Atrophy (SMA) to improve motor function and survival. A feature of adult SMA patients is a progressive neuromyopathic scoliosis, so spinal nusinersen administration can be challenging. Landmark identification using a pre-procedure ultrasound (US) facilitates technical performance of spinal anesthesia and allows for the elimination of radiation exposure. The aim of this randomized prospectic study is to determine if the US assistance for spinal administration of nusinersen is able to increase the proportion at successful 1st needle insertion of the needle. Secondary outcome measures are procedure time, patient satisfaction and prevalence of postdural puncture headache. Patients will be randomlized to receive a US-assisted nusinersen administration or a landmark based nusinersen administration.
In 2019, KDOQI considered that uremic patients with a life expectancy of more than one year should require hemodialysis as an effective renal replacement therapy before preparation of kidney transplantation. Arteriovenous fistula, as the lifeline of uremic patients, plays an important role in their daily hemodialysis. The patency of arteriovenous fistula is largely restricted by the inflow artery. According to available medical literatures, an incidence rate of variations in the branching pattern of the main arteries in the upper limb is ranged from 7.2% to 25.0%. and there is a large difference in the incidence rate between sex and race, furthermore, the incidence rate of variations in the branching pattern of the main arteries in the upper limb of Chinese is still unclear. The brachial artery is the main artery of the upper limb. It gives off two terminal branches at the distal end of the elbow crease, the radial and ulnar arteries, the former one often serves as an arterial inflow to create an arteriovenous fistula in the forearm. High bifurcation of the brachial artery (HBBA) seems to be a common variation which may result in immaturity or disfunction of arteriovenous fistulas. Therefore, the purpose of this study is to investigate the variations in the branching pattern of the main arteries in the upper limb of Chinese, in order to study on the hemodynamic changes, and their influence on the establishment, maturation and failure of arteriovenous fistulas in the upper limb.
Prehospital emergency ultrasound (PEU) is being increasingly used in different preclinical emergency systems across the world. Ultrasound examinations in emergency situations, however, remain challenging even in the hospital setting despite the availability of standardized approaches such as Focused Assessment with Sonography for Trauma (FAST). Preclinical circumstances further complicate the adequate execution of an additional diagnostic tool such as PEU on the scene or inside a medical emergency vehicle. Furthermore, rapid translation of ultrasound findings into meaningful therapeutic consequences is considerably demanding in an environment of limited resources. If focused PEU is correctly used and patients' condition allows emergency doctors a careful ultrasound examination, it is possible to differentiate life-threatening diagnoses. PEU should be implemented in the management of emergency patients affected by trauma, cardiac arrest/shock or respiratory problems. To date it is unclear whether PEU results in improved outcome. Some emergency cases present difficult challenges in the prehospital ultrasound examination. Portable devices designed for PEU suggest the possibility of increasing the use of ultrasound "in the field". However, to the investigator's knowledge, opportunities for real-time consultation with a second specialist including live transmission of the ultrasound picture are not being provided at any preclinical emergency facility.
Aim: Although regional anesthesia (RA) techniques are advantageous in the anesthetic management of obese patients (body mass index (BMI)≥30); their performances can still be associated with technical difficulties and greater failure rates. The aim of this study is to compare the performance properties and analgesic efficacy of ultrasound (US)-guided bilateral thoracic paravertebral blocks (TPVBs) in obese and non-obese patients. Material methods: After obtaining ethics committee approval; data of 82 patients, who underwent elective bilateral reduction mammaplasty under general anesthesia with adjunctive TPVB analgesia between December of 2016 and February of 2020, were reviewed. Patients were allocated into two groups with respect to their BMI scores (Group NO: BMI<30 and Group O: BMI≥30). Demographics, TPVB ideal US image visualization and performance times, needle tip visualisation and TPVB performance difficulties, number of needle maneuvers, surgical, anesthetic and analgesic follow-up parameters, incidence of postoperative nausea vomiting (PONV), sleep duration, length of postanesthesia care unit (PACU) and hospital stay, patient and surgeon satisfaction scores were all investigated and compared.
Sonazoid as a new generation of ultrasound contrast agent. This study based on the features of Sonazoid specific angiography and high mechanical index, the role of Sonazoid in the differential diagnosis of thyroid benign and malignant tumors was explored.
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.
