NCT ID: NCT01371188 Completed - Oxidative Stress Clinical Trials

Effects of Exposure to Biomass-burning Air Pollution on Lung Function, Heart Rate Variability and Inflammatory Markers in Sugarcane Workers

Start date: December 2008
Phase: N/A
Study type: Observational

Introduction: Non-mechanized sugar cane harvesting preceded by burning, an important and prevalent professional activity of agribusiness segment of the Brazilian economy, exposes workers and people of neighboring towns to high concentrations of pollutants and, therefore, potentially several risks to health hazards. Objectives: Assessing cardiopulmonary impacts and inflammatory markers in sugarcane workers and volunteers from a nearby town in non-harvest and harvest periods.

NCT ID: NCT01169038 Completed - Clinical trials for Pulmonary Sarcoidosis

Investigation of the Efficacy of Antibiotics on Pulmonary Sarcoidosis

CLEAR Lung
Start date: July 2010
Phase: Phase 1
Study type: Interventional

Sarcoidosis is a granulomatous disease for which the molecular and immunologic association with mycobacteria continues to strengthen. The investigators are interested in conducting a proof-of-concept investigation of the effects of antibiotics on sarcoidosis resolution. The investigators hypothesize that pulmonary sarcoidosis will improve faster if patients are given antimycobacterial therapy, in addition to their standard therapy.

NCT ID: NCT01048021 Completed - Lung Function Clinical Trials

Pulmonary Function Changes and Diaphragmatic Paralysis Following Ultrasound Guided Supraclavicular Brachial Plexus Blockade: The Effects of Decreased Local Anesthetic Volume

Start date: October 2009
Phase: N/A
Study type: Observational

This clinical trial is being conducted to study lung function and movement of the major muscle involved in breathing (the diaphragm) after a brachial plexus nerve block (nerve "freezing"). The purpose of this study is to find out what effects (good and bad) ultrasound guided nerve freezing has on the movement of the patient's diaphragm and their lung function. The potential advantage of ultrasound guidance will be a lesser chance of freezing the nerves that innervate the diaphragm and thus having less of an effect on lung function.

NCT ID: NCT01004146 Completed - Bariatric Surgery Clinical Trials

Pre-op Use of Incentive Spirometry in Obese Patients

IS
Start date: March 2009
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the use of preoperative incentive spirometry (IS) as an aid to improve postoperative lung function. The hypothesis is that application of a standardized protocol of preoperative respiratory care teaching and exercise will improve lung performance that will subsequently result in prevention of postoperative pulmonary complications and that increasing the duration of preoperative use better improves lung mechanics postoperatively. The investigators propose to compare a patient population that uses IS as currently prescribed in the routine course of care (only to be familiar with preoperatively, but use postoperatively) against a population that uses IS with a standardized regimen for at least 3 days prior to the operation in terms of preoperative IS volumes, intraoperative pulmonary mechanics, postoperative IS volumes, and incidence of postoperative pulmonary complications.

NCT ID: NCT00845143 Unknown status - Clinical trials for Non-Small Cell Lung Cancer

Vibration Response Imaging (VRI) in the Preoperative Management in Patients With Non-Small Cell Lung Cancer

Start date: February 2009
Phase: N/A
Study type: Observational

The purpose of this study is to assess the correlation of the predicted post-operative lung function with the observed post-operative lung function (FEV1 and DLCO) in patients who underwent surgical resection (FEV1 = Forced expiratory volume in 1-second. DLCO = Diffusion capacity for carbon monoxide. ppo = predicted postoperative.)and versus the gold standard QRRVP (Quantitative Radionuclide Study of Regional Lung Ventilation and Perfusion)

NCT ID: NCT00706277 Completed - Lung Function Clinical Trials

Effect of Total Intravenous Anesthesia and Balanced Anesthesia on Postoperative Lung Function

Start date: June 2008
Phase: Phase 4
Study type: Interventional

The aim of the study is to investigate the effects of total intravenous anesthesia (TIVA; propofol, remifentanil) and balanced anesthesia (BAL; induction with propofol and fentanyl; maintenance of anesthesia with sevoflurane and nitrous oxide) on pulmonary function 30 minutes after emergence from the general anesthesia.
