Filter by:Percutaneous nephrolithotomy (PNL) is frequently used today for renal stones. percutaneous nephrolithotomy (PNL) procedure has become the treatment of choice for many patients with symptomatic renal stones . Patients undergoing PNL suffer from acute postoperative pain, despite a multimodal analgesic regime. This is a randomised controlled trial efficacy of the anterior Quadratus Lumborum Block (QLB) in terms of analgesic efficacy in patients who undergo percutaneous nephrolithotomy.
This study in part of a larger cohort study (clinical trials ID number: NCT03375333) that examine the use of ultrasound in general practice. In the present study patient experiences, with use of ultrasound in the consultation at the general practitioners office, will be explored through a questionnaire.
This study explores how Point of Care Ultrasound (POC-US) is used in general practice in Denmark and how it affects the diagnostic process and treatment of patients. Twenty general practitioners (GPs) will register information each time they use POC-US during a one month period. The information will include indications and frequencies of the performed POC-US examinations, change in tentative diagnosis, plan, and treatment before and after the use of POC-US in relation to confidence in the tentative diagnosis, findings and quality of the POC-US examination. This is an observational study without any intervention.
Analgesia following tympanomastoid surgery is critical for the prevention of postoperative . There are very few regional anesthesia methods used to achieve this goal.
Point-of-care ultrasound (POCUS) has been found to be useful for aiding in the prediction of fluid responsiveness. It is unknown if trainees can effectively utilize this tool to improve their assessment of fluid responsiveness. In this prospective, observational study, pulmonary and critical care fellows are asked to make 2 assessments of fluid responsiveness in adults with shock: (1) based on clinical exam alone (Clinical) and (2) after performing a POCUS (Clinical + US). The accuracy of their pre- and post-ultrasound assessments are compared using a bioreactance monitor and passive leg raise test as the gold standard of fluid responsiveness in this study.
This preliminary study investigates in patients with possible clinical diagnosis of pneumonia, clues and biomarker assessed at Emergency Department (ED) triage, potentially predicting detection of lung consolidation by Thoracic-ultrasound (TUS) and/or by Chest-X-Rays. Cough and high admission CRP levels will be defined according to the cutoff defined by ROC analysis, will be challenged if independently associated with TUS lung consolidation detection High level of the chosen biomarker, and any of the considered symptoms, in otherwise not extremely critical patients (CURB65≤3), should prompt to immediate confirm by TUS, during the physical examination. This may limit the need of further radiological investigations allowing targeted workup.
The aim of this double blinded study is to assess the abilities of the SpineNav3DTM technology (Accuro) to identify the lumbar epidural space in parturients using as comparator a standar ultrasound (US) device.
The prospective study will include 200 patients and 50 critically ill patients, who had an abdominal computed tomography (CT) scan including the L3 level for any clinical reason. Ultrasound scans of the anterior thighs and forearms will be taken after the CT scan within 48 hours. Bioelectrical impedance analysis (BIA) will also be performed. In addition muscle strength, mobility, physical function and nutrition will be assessed. Primary outcome is the prediction of CT-based whole body muscle and fat volume and BIA-based fat and lean body mass from ultrasound-based muscle and fat thickness. Other secondary outcomes include the intra- and interrater reliability of the CT evaluation and ultrasound examination of muscle and fat mass. The relationship between clinical aspects (strength, mobility, physical function, nutrition) and whole body composition is another secondary outcome.
The goal of this study is to assess the impact of perioperative point-of-care ultrasound (POCUS) assessment on patient-important outcomes (e.g. hospital length of stay, length of stay in recovery, mortality etc.) and perioperative patient management strategies, in patients undergoing non-elective non-cardiac surgeries.
The purpose of this single-blind, randomized control trial will be to investigate whether simply having warmed gel, as compared to room-temperature gel, during a bedside ultrasound significantly improves patient satisfaction scores.
