Filter by:To evaluate the usefulness of Deep neural network (DNN) in the evaluation of mediastinal and hilar lymph nodes with Endobronchial ultrasound (EBUS). The study will explore the feasibility of DNN to identify lymph nodes and blood vessel examined with EBUS.
Purpose: Researchers wanted to investigate the effect of capnography monitoring in addition to routine monitoring on the development of desaturation and other vital parameters in endobronchial ultrasonography (EBUS) cases. Method: 100 patients who underwent EBUS under sedation will be included in this prospective and randomized controlled study. The cases will be divided into two groups of 50 people each. In the first group, standard monitoring will be performed, and in the second group, in addition to standard monitoring, capnography monitoring will be used. Heart rate, blood pressure, peripheral oxygen saturation (SpO2) values in both groups, end-tidal carbon dioxide (EtCO2), respiratory rate and integrated pulmonary index (IPI) values in the second group will be recorded in all cases. Disturbances in vital parameters and airway interventions, which were common in both groups, will ve compared. The frequency of problems detected by capnography monitoring in the second group will be examined.
Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is a routine procedure that is performed to sample mediastinal lymph nodes. At author's center the EBUS-TBNA procedure is performed under conscious sedation using midazolam. During the EBUS procedure, oxygen supplementation can either be provided using low flow or high flow through a nasal cannula. The investigators hypothesize that the use of high flow nasal cannula (HFNC) for oxygen supplementation during EBUS would be associated with lesser incidence of clinically significant hypoxemia (SpO2 ≤90%) when compared to conventional nasal cannula. In this study, the authors plan to assess the efficacy of HFNC in reducing the incidence of hypoxemic events in subjects undergoing EBUS under conscious sedation.
Before any treatment decisions are made for patients with lung cancer, it is crucial to determine whether the cancer has spread to the lymph nodes in the chest. Traditionally, this is determined by taking biopsy samples from these lymph nodes, using the Endobronchial Ultrasound Transbronchial Needle Aspiration (EBUS-TBNA) procedure. Unfortunately, in 40% of the time, the results of EBUS-TBNA are not informative and wrong treatment decisions are made. There is, therefore, a recognized need for a better way to determine whether the cancer has spread to the lymph nodes in the chest. The investigators believe that elastography, a recently discovered imaging technology, can fulfill this need. In this study, the investigators are proposing to determine whether elastography can diagnose cancer in the lymph nodes. Elastography determines the tissue stiffness in the different parts of the lymph node and generates a colour map, where the stiffest part of the lymph node appears blue, and the softest part appears red. It has been proposed that if a lymph node is predominantly blue, then it contains cancer, and if it is predominantly red, then it is benign. To study this, the investigators have designed an experiment where the lymph nodes are imaged by EBUS-Elastography, and the images are subsequently analyzed by a computer algorithm using Artificial Intelligence. The algorithm will be trained to read the images first, and then predict whether these images show cancer in the lymph node. To evaluate the success of the algorithm, the investigators will compare its predictions to the pathology results from the lymph node biopsies or surgical specimens.
The purpose of this study is to investigate whether chlorhexidine mouthrinse is effective in preventing microbial contamination during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).
The study is aimed to evaluate the sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate of endobronchial ultrasound (EBUS) image features in diagnosing peripheral pulmonary lesions (PPLs).
The randomized controlled trial will compare efficacy and safety of dexmedetomidine to midazolam for sedation during endobronchial ultrasound
