Pulmonary thromboembolism with transthoracic ultrasound and computed tomography angiography

Abstract

Objective: The detection of pulmonary embolism in emergency department requires an urgent therapeutic and diagnostic attention. This study was performed to determine the accuracy and efficacy of ultrasound in the diagnosis of pulmonary embolism. Methods: In this study, 110 patients who referred to the emergency department with traumatic embolism symptoms were enrolled. All the patients underwent computed tomography (CT) angiography. Patients were divided into positive and negative outcomes according to the results of transthoracic ultrasonography and CT angiography. Results: In this study, 110 patients were enrolled, of whom 52 (47.3%) were male and 58 (52.7%) were female. Among the patients, 100 (90.9%) patients presented with dyspnea, whereas the frequency of pleural pain was 27% (24.5%). Sensitivity, specificity, positive predictive value, and negative predictive value for ultrasound were 45.67%, 77.41%, 88.09%, and 35.29%, respectively. The positive outcomes from CT scan were significantly associated with gender, p = 0.005. The gender and transthoracic ultrasonography outcomes were also significantly correlated, p = 0.019, and the outcomes of ultrasound were significantly different from those of CT scan, p = 0.008. Conclusion:Transthoracic ultrasonography may be used to diagnose pulmonary embolism as a technique in the emergency department, especially in patients who are unable to move due to the severity of the disease. However, further comparative studies are required in this aspect.

The Difference in Mouthwash Side Effects of Persica and Chlorhexidine for Preventing Ventilator-induced Pneumonia among Patients Admitted to the Intensive Care Unit

“…Thereby, decontamination of the mouth and throat using antiseptics is recommended to reduce the aspiration of already existing pathogens in the oral cavity [4]. Based on the guidelines provided by the Centers for Disease Control and Prevention (CDC), staff hygiene and sanitization, use of gloves when dealing with infected patients and in contact with respiratory membrane [5], the elevation of the head of the bed to 30º to 45º, and routine management of oral hygiene for oropharyngeal decontamination using Chlorhexidine Gluconate antiseptic [6]. Chlorhexidine is commonly used in mouthwash to prevent plaque.…”

Comparison of Doppler Ultrasound and Digital Subtraction Angiography in extracranial stenosis

“…Most recently, non-invasive techniques have also been suggested for assessing the luminal stenosis such as Duplex Ultrasound Sonography (DUS), Magnetic Resonance Angiography (MRA), and Computed Tomography Angiography (CTA) [ [9] , [10] , [11] ]. Among these, DUS serves as primary screening tool for carotid stenosis, as it is available and cost-effective in most healthcare centers including ours.…”

Comparative study of the effect of two different doses of remifentanil on bleeding control in lumbar fusion surgery: A randomized clinical trial

“…Excessive bleeding during surgery, in addition to reducing the surgeon's view of the surgical field, causes more trauma to the surrounding tissues, and the longer the period, the better the recovery period [ 15 ]. Controlled hypotension reduces bleeding from the surgical incision, thereby providing technical freedom and better vision for the surgeon in terms of operating more accurately [ 16 , 17 ]. In controlling hypotension, drugs such as Trimetaphan and pentolinium, vascular wall muscle relaxants such as hydralazine, sodium nitroprusside, and beta-blockers including propranolol [ [18] , [19] , [20] ].…”
