NCT ID: NCT06211946 Completed - Clinical trials for Abdominal Aortic Aneurysm

Abdominal Aorta Palpation With Point of Care Ultrasound Imaging Measurements

Start date: January 25, 2024
Phase:
Study type: Observational

The goal of this observational study is to compare the measurements of abdominal aorta width via palpation and point of care ultrasound imaging in healthy individuals. The main question[s] it aims to answer are: - Is there a measurement difference in abdominal aorta width in healthy individuals as measured by palpation and point of care ultrasound imaging? - Are palpation measurements and point of care ultrasound imaging measurements reliable when performed by physical therapy researchers? Participants will be asked to have their abdominal area be palpated around the umbilicus and will have ultrasound imaging performed over their abdominal aorta area. It is anticipated participation in the study will take less than 15 minutes. Subjects will be asked to return for a repeat visit within 1 month to determine reliability of measurements.

NCT ID: NCT06068647 Recruiting - Clinical trials for Chronic Obstructive Pulmonary Disease

Ultrasound and Respiratory Physiological Signals in Lung Diseases

SAURON
Start date: March 22, 2023
Phase: N/A
Study type: Interventional

The use of lung ultrasound is instrumental in the evaluation of many chest pathologies and its ability to detect pleuro-pulmonary pathology is widely accepted. However, the use of ultrasound to explore the state of the peripheral lung parenchyma, when the organ is still aerated, is a relatively new application. Horizontal and vertical artifacts are separate and distinct artifacts that can be seen during ultrasound examination of the lungs. While the practical role of lung ultrasound artifacts is accepted to detect and monitor many conditions, further research is needed for the physical interpretation of ultrasound artifacts. These artifacts are diagnostic signs, but we don't fully understand their origin. The artifactual information deriving from the surface acoustic interaction, beyond the pleural line, in the ultrasound images of the normally aerated and non-deflated lung, represents the final result of complex interactions of acoustic waves with a specific three-dimensional structure of the biological tissue. Thus, the umbrella term "vertical artifacts" oversimplifies many physical phenomena associated with a pathological pleural plane. There is growing evidence that vertical artifacts are caused by physiological and pathological changes in the superficial lung parenchyma. Therefore, the need emerges to explore the physical phenomena underlying the artifactual ultrasound information deriving from the surface acoustic interaction of ultrasound with the pleuro-pulmonary structures.

NCT ID: NCT05900440 Enrolling by invitation - Education, Medical Clinical Trials

Artificial Intelligence for Learning Point-of-Care Ultrasound

Start date: June 1, 2021
Phase: N/A
Study type: Interventional

Point-of care-ultrasonography has the potential to transform healthcare delivery through its diagnostic and therapeutic utility. Its use has become more widespread across a variety of clinical settings as more investigations have demonstrated its impact on patient care. This includes the use of point-of-care ultrasound by trainees, who are now utilizing this technology as part of their diagnostic assessments of patients. However, there are few studies that examine how efficiently trainees can learn point-of-care ultrasound and which training methods are more effective. The primary objective of this study is to assess whether artificial intelligence systems improve internal medicine interns' knowledge and image interpretation skills with point-of-care ultrasound. Participants shall be randomized to receive personal access to handheld ultrasound devices to be used for learning with artificial intelligence vs devices with no artificial intelligence. The primary outcome will assess their interpretive ability with ultrasound images/videos. Secondary outcomes will include rates of device usage and performance on quizzes.

NCT ID: NCT05872906 Recruiting - Ultrasound Imaging Clinical Trials

Using Ultrasound and Acupuncture to Explore the De-qi Location and Reaction of Specific Acupoints

Start date: March 6, 2023
Phase: N/A
Study type: Interventional

According to ancient literature, when de qi occurs in the process of acupuncture, the patient may experience sensations such as soreness, numbness, heaviness, swelling. Meanwhile, the acupuncturist may experience the sensation of "a fish taking a bite from the bait on a hook". However, for a beginner at acupuncture, before they have learned to trigger the de qi sensation, it is hard for them to learn according to the ambiguous definition of "a fish taking a bite from the bait on a hook" and thus hard to know whether they have reached the correct location and stimulated de-qi. In this study, through multiple experienced acupuncturists acupuncture multiple test subjects, the investigators will locate the location and the reaction of de qi on the acupoint Quchi (LI11) with ultrasound observation and recording. Through the ultrasound teaching and guidance, the investigators will test whether it is possible to reversely use ultrasound imaging to guide less experienced acupuncturists to the de qi location and elicit de qi response on multiple test subjects. Therefore, the investigators propose this study to test the following hypothesis:"There is a specific anatomical site where de qi occurs at LI11, and it is possible to use ultrasound imaging to guide learners to reach that location and trigger de-qi and that it is applicable to other acupoints". To explore the above hypothesis, the investigators will target the following specific aims. Aim 1: Use ultrasound record and indicate the precise anatomical location and reaction when de qi occurs on acupoint LI11. Aim 2: Simultaneously record the physicians' needling sensations, the participants' needling sensations, twitch response of the participant under ultrasound images. Aim 3: Prove the feasibility of using ultrasound to guide inexperienced physicians to reach the correct location and elicit de qi sensation on the participants. Aim 4: Discuss the relationship between de qi and pulse diagnosis. Aim 5: Apply the above procedures to other acupuncture points such as LU5(Chize), PC3 (Quze),…etc.

NCT ID: NCT05807737 Completed - Ultrasound Imaging Clinical Trials

A Study to Assess the Accuracy of Artificial Intelligence for Ultrasound-guided Regional Anesthesia

Start date: October 15, 2020
Phase:
Study type: Observational

The goal of this observational study is to assess the accuracy of Artificial Intelligence (AI) software to assist ultrasound scanning prior to peripheral nerve blocks. 40 healthy volunteers are going to be accepted to this study in which ultrasound scanning will be performed for four different block types. The main questions it aims to answer are: - Can Nerveblox, the artificial intelligence software highlight and find the key anatomical landmarks on the provided nerve or plane block correctly? - Can the user obtain a correct view of provided nerve or plane block, when the AI software scan success reaches 100%? Participants will be evaluated under four nerve block regions to identify their key anatomical landmarks using ultrasound-guided artificial intelligence software. Three residents with different levels of Ultrasound-guided Regional Anesthesia(UGRA) experience but eligible to perform UGRA techniques will collect the ultrasound images when the artificial intelligence software scan success fed by ultrasound reached 100%. After collecting US images, each pair of US images(highlighted and raw ) will be evaluated by 2 experts for the accuracy of AI assistance, independently and blindly.

NCT ID: NCT04822116 Completed - Clinical trials for Postoperative Complications

Continuation of Goal Directed Haemodynamic Optimization in the PACU

Start date: April 24, 2019
Phase: N/A
Study type: Interventional

Post-operative monitoring of all patients after anaesthesia in the post anaesthesia care unit (PACU) is standard of care today. It helps to reduce morbidity and even mortality in high-risk patients. In addition to clinical monitoring by qualified staff, standard monitoring in the PACU includes non-invasive, intermittent, haemodynamic monitoring. This research is going to investigate the influence of the continuation of goal directed haemodynamic optimization in the recovery room on the basis of non-invasive monitoring tools, i.e. ultrasound and the volume-clamp method, in regard of length of stay in the PACU and postoperative complications.
