Filter by: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.
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.
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.
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.
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.
