Active clinical trials for "Pleural Effusion"

The primary objective of this prospective trial will be to assess the effects of dexmedetomidine administration on oxygenation and respiratory function in patients undergoing diagnostic or therapeutic medical thoracoscopy/pleuroscopy for a pleural effusion compared to conventional conscious sedation/monitored anesthesia care (MAC) with midazolam. The secondary endpoint of the study will be to also assess the effects of dexmedetomidine administration on respiratory mechanics and postprocedural complications

Tubercular pleural effusion is the second most common form of extrapulmonary tuberculosis (EPTB) seen in clinical practice after tuberculosis (TB) lymphadenitis. It is common that after complete treatment of the patient with tubercular pleural effusion with six months of the short-course chemotherapy under Directly Observed Treatment Short-Course (DOTS), pleural effusion has not resolved completely. In these cases treatment need to be extended for one or two more months by giving extension pouches. Since DOTS does not recommend demonstration of complete resolution of tubercular pleural effusion at the end of treatment completion, there is paucity of data in terms of the patients declared cure for the sputum negative pulmonary and extra-pulmonary TB as such which includes TB pleural effusion as well. This project aims to look into the patient characteristics, treatment outcome, and compute the number of cases which require an extended regimen and to what extent is the pleural effusion persistent at the end of six months of standard DOTS therapy.

Pleural fluid glucose levels measured with bed-side point of care methods such as finger stick glucometers and I-STAT device correlate with the traditional in-lab testing methods.

Research project objectives. The project includes eight research hypotheses and eight corresponding study objectives. The most relevant objectives are: Analysis of lung function and gas exchange parameters in relation to the removed pleural fluid volume and intrapleural pressure changes. Evaluation of changes in lung and chest wall compliance and related changes in work of breathing during therapeutic thoracentesis and pleural fluid withdrawal. Study of the relationship between intrapleural pressure changes and cardiac function assessed by echocardiography and alterations in serum natriuretic peptide A and B concentration. Comparative analysis of the reliability of the volume-pressure curve slope prediction based on different variables measured before thoracentesis and real measurements of ventilation and intrapleural pressure during thoracentesis. 2. Research methodology The study will be performed in 60 patients with pleural effusion planned for therapeutic thoracentesis. Studies before thoracentesis: body plethysmography, spirometry, lung diffusion capacity (DLCO), arterial blood gases, 6 minute walk test, echocardiography, serum natriuretic peptide concentration. Evaluation during thoracentesis: continuous measurement of tidal breathing and respiratory rate, measurement of removed pleural fluid volume and intrapleural pressure, transcutaneous measurement of PO2 and PCO2. Pleural catheter will be retained for the next 48hours to enable fluid drainage and intrapleural pressure measurement after completion of thoracentesis. Monitoring during 48-hrs after thoracentesis: pre-thoracentesis measurements will be repeated in specific time points and compared in two subgroups (active physiotherapy to improve lung re-expansion and passive lung re-expansion). Intrapleural pressure will be measured 24 and 48 hours after thoracentesis. Then, the catheter will be removed. Analysis.Signal analysis and visual multidimensional analysis performed with the use of own computer programs will be the first step of the analysis. The identified relationships between the analyzed parameters should allow to form physiological, medical, and statistical hypotheses, as well to verify the analysis of previously obtained data . Expected impact of the research project The study results will allow to define lung function, blood gases and cardiovascular function in relation to changes in intrapleural pressure. Some of these correlations had not been previously investigated. Our results may influence management standards in patients who require therapeutic thoracentesis.

The goal of this clinical research study is to compare 2 different methods for treating a pleural effusion. Researchers also want to learn how the treatment you receive effects your quality of life (your ability to do the things you like to do and how happy you feel.

Collections of fluid around the lung (pleural effusions) are common in patients on mechanical ventilation. Long stays on mechanical ventilation can lead to serious complications such as pneumonia and are associated with significant morbidity and mortality. The drainage of pleural effusions may lead to improvements in oxygenation making it easier to discontinue mechanical ventilation. The purpose of this study was to examine the effects of thoracocentesis (pleural fluid drainage) on blood oxygenation over a 48 hour period to see whether the effects are sustained and therefore helpful in this discontinuation.

The objective of the explorative registry study is to investigate outcome parameters in the routine treatment of patients who are monitored after heart surgery for either short or long-term treatment in the intensive care unit for close monitoring of blood pressure.

Background: Rigid thoracoscopy is the gold standard tool for diagnosing exudative pleural effusion but sometimes it is difficult to obtain sufficient biopsies using the conventional forceps. Objectives: This study evaluated the efficacy, safety and diagnostic value of a modified technique using cryoprobe to obtain pleural biopsies during thoracoscopy. Methods: This is a single center prospective study in patients who will undergo rigid thoracoscopy using conventional rigid forceps followed by a cryoprobe from the same site after injection of subpleural mixture of adrenaline and xylocaine. Biopsies will be reviewed by an independent pathologist; any complications will be recorded, and all patients will be followed up post procedure.

Community acquired pneumonia (CAP) is still one of the most important causes of morbidity in adults. (1) In severe cases, parapneumonic effusions or empyema may develop. In these patients, a transitional fibrin neomatrix constitutes part of the acute inflammatory response as seen in sepsis. The aim is to study the fibrinolytic activity in patients with CAP alone versus CAP with parapneumonic effusions with and without empyema.

This is a multicenter retrospective study that collected diagnostic information of patients with pleural effusion. The overall survival (OS) time of malignant patients was followed up, defined as the time from diagnosis to death. Clinical data and residual pleural effusion specimens were collected from patients. Metabonomics was utilized to differentiate between benign and malignant pleural effusion and to evaluate the prognosis of lung cancer patients with malignant pleural effusion.
