Active clinical trials for "Bronchial Spasm"

The most common adverse event in endoscopic procedures is hypoxia. Different airway devices have been investigated in the literature to prevent hypoxia. This study aimed to compare the efficacy and procedural performance of two different airway (GLT and WNJ) devices in ERCP procedures.

The purpose of this study is to evaluate the effectiveness of two different ways to teach hospitalized children how to use a metered dose inhaler and to follow-up after discharge home from the hospital to determine durability of the education.

The incidence of physician confirmed asthma is approximately 4-7% in children. An additional 5% of children suffer from infection-related bronchiolitis and obstructive bronchitis. Of all patient visits at pediatric emergency rooms, 1 out of 10 is due to breathing difficulties with a great proportion leading to hospitalization. Salbutamol is the most commonly used drug in the treatment in acute bronchial obstruction. A vast majority of children require a spacer device (valved holding chamber, VHC) for the delivery of the drug aerosol. There are several different types of VHC on the market, but no recommendations on the device selection have been published. Both in in vivo and in vitro studies significant differences between different spacer devices have been reported. The study compares two different VHCs in the treatment of acute breathing difficulties in children. The end-points in this randomized physician-blinded study are symptom relief, rate of hospitalization, symptom recurrence, treatment compliance, and adverse events. The study will be conducted in pediatric emergency rooms (ER) in three university hospitals in Finland and one private clinic that routinely treat this type of patients. The treatment is given according to national treatment guidelines and no blood samples are drawn for study purposes. Both of the VHCs used in this study have been approved for use in clinical practice.

The purpose of this study is to determine if treatment of exercise-induced Bronchospasm with montelukast will help college athletes train more effectively and thus become more competitive in a non ergogenic manner.

Despite few scientific evidence that could support the use of ketamine in adult patients undergoing acute bronchospasm requiring mechanical ventilation (MV), ketamine is largely employed in this setting. The aim of this study is therefore assess more definitively the real benefit of using ketamine in patients with severe bronchospasm, requiring ICU stay and need for MV in order to establish or refute the use of this drug as "standard therapy" in these cases.

The study will be conducted in two hospitals of the same geographic area. It will be included children <3-years-old with recurrent wheezing attacks, confirmed by the review of the medical records, in the previous 12 months or a shorter time for those younger than one year.

The purpose of this research is to assess the association between diet and pulmonary function during standardized EIB testing. Determine the effect of Vitamin C supplementation on airway inflammatory markers and bronchoconstriction after a standardized EIB test compared to usual diet and placebo control.

Exercise is an important clinical feature in cystic fibrosis. Better exercise capacity has been associated with better patient outcomes and quality of life. Exercise-induced bronchospasm is a condition, often associated with asthma, which may make exercise difficult. The role that exercise-induced bronchospasm has in people with cystic fibrosis is unknown. This study is designed to determine how often exercise-induced bronchospasm occurs in cystic fibrosis.

Background There is no unanimous opinion about a lung-protective strategy in cardiac surgery. Small randomized clinical and animals trials suggest that ventilation during cardio-pulmonary bypass (CPB) could be protective on the lungs. This evidence is based on surrogate end-points and most of studies are limited to elective coronary surgery. According to the available data, an optimal strategy of lung protection during CPB cannot be recommended. The purpose of the CPBVENT study is to investigate the effectiveness of different ventilation strategies during CPB on post-operative pulmonary complications. Trial design The CPBVENT study will be a single-blind, multicenter, randomized controlled trial. We are going to enroll 780 patients undergoing elective cardiac surgery with planned use of CPB, aortic cross-clamping and two lung ventilation. Patients will be randomized into three treatment groups: 1) no ventilation during CPB; 2) continuous positive airway pressure (CPAP) with positive end-expiratory pressure (PEEP) of 5 cmH2O during CPB; 3) ventilation with 5 acts/minute with tidal volume of 2-3 ml/Kg and a PEEP of 3-5 cmH2O during CPB. The primary end-point will be the incidence of a PaO2/FiO2 ratio <200 until the time of discharge from the ICU. The secondary end-points will be the incidence of post-operative pulmonary complications and 30-days mortality. Patients will be followed-up to 12 months after the date of randomization. Summary The CPBVENT Trial will determine whether different ventilation strategies during CPB will improve pulmonary outcome in patients undergoing cardiac surgery.

This research is being conducted to help us better understand what causes exercise induced asthma. The investigators hypothesize that two types of chemicals, cysteinyl leukotrienes and adenosine, play an important role. The investigators will be measuring these chemicals in the exhaled breath of volunteers with exercise induced asthma as they undergo a test to mimic exercise induced asthma. The investigators will determine how the levels of these chemicals change in association with how lung function changes before, during and after an episode of exercise induced asthma.
