Active clinical trials for "Respiratory Aspiration"

The purpose of the present project is to compare High-Flow Nasal Oxygen therapy with Standard Oxygen therapy, initiated in the prehospital setting in patients with acute hypoxemia respiratory failure, in terms of oxygenation at arrival to the hospital and need of mechanical ventilation during the subsequent 28 days

This study aimed to compare the efficacy between lidocaine inhalation vs intravenous dexamethasone to reduce pain after laryngeal mask insertion

The purpose of this study is to assess the efficacy of inspiratory muscle strength training for lowering blood pressure and improving physiological function (vascular, motor, and cognitive) in middle-aged and older adults with elevated systolic blood pressure.

Comparable RCTs of clinical therapeutic effects using respiratory physiology-oriented IMT device in different operation principle in COPD are so far lacking. Therefore the investigators perform an adequately powered RCT on the effects of two IMT device application as an pulmonary physical therapy in patients with COPD with inspiratory muscle weakness.

High-flow nasal cannula (HFNC) is a method of non-invasive respiratory support used to decrease the effort of breathing (EOB) in patients with a wide variety of respiratory diseases in the pediatric intensive care unit. While its use has shown association with decreased rates of mechanical ventilation, there is a paucity of data examining its direct effect upon objective measurements of EOB. This study will aim to evaluate objective measurements of EOB in response to different levels of HFNC support, characterize the natural course of respiratory diseases treated with HFNC, evaluate changes in EOB secondary to the administration of supplemental medical therapies used in conjunction with HFNC, and compare different physiologic metrics for quantifying EOB in patients on HFNC.

Even with the advances in clinical therapy and percutaneous interventions, coronary artery bypass grafting (CABG) is still widely used in the treatment of patients with coronary artery disease (CAD). However, it is a complex procedure that triggers important organic implications especially on pulmonary function. In relation to the treatment of patients undergoing CABG, the recovery is linked to the cardiac rehabilitation programs. These programs can also be associated with other muscle training measures, among these there is inspiratory muscle training (IMT). Most studies has been implemented moderate-intensity IMT daily, but there are few studies about the effects of high intensity training loads performed on alternate days. In this context, is justified the use of a device such as the recent Powerbreathe, which uses higher training loads that would provide greatest benefits, whereas the magnitude of the response to training tends to increase with load. OBJECTIVE: To investigate the efficiency of high intensity IMT associated with combined aerobic and resistance training on maximal exercise capacity, submaximal exercise capacity, respiratory muscle strenght, pulmonary function, oxidative stress, quality of life and endothelial function in patients who underwent CABG in phase II cardiac rehabilitation program. METHODOLOGY: This is a clinical trials, controlled, randomized,double-blind being developed in partnership with Cardiology Clinic of Hospital Universitário de Santa Maria (HUSM), Santa Maria, RS, Brazil. Patients will undergo the evaluation of pulmonary function and respiratory muscle strength (spirometry and digital manovacuometry), as well on the maximal exercise capacity (Ergospirometry), submaximal functional capacity (6MWT and 6MST), of quality of live (MLHFQ) of Oxidative stress and endothelial function (blood biomarkers). After the evaluation will be randomly allocated into two groups: the control group will perform cardiac rehabilitation associated with the Sham of IMT, and the experimental group cardiac rehabilitation associated with the IMT High-intensity. The intervention will last twelve weeks for both groups and after this phase patients will be submitted again to the assessment tools. EXPECTED RESULTS: The high intensity IMT potentiates the effects of cardiac rehabilitation (phase II) after coronary artery bypass surgery patients.

Inhalation burn injury and lung complications caused by large surface burns occurring during a fire remains a serious problem. Pulmonary rehabilitation has been used successfully to improve pulmonary function(PF) in patients with chronic obstructive pulmonary disease. But there were no studies that pulmonary rehabilitation induce improvements in PF in patient with large surface burn and inhalation injury. The investigators will performe pulmonary function and respiratory muscles strength evaluation in 40 patients with thermal injury in order to evaluate the effects of pulmonary rehabilitation in patients with thermally injury.

This study evaluates the influence of two different end-inspiratory pause (EIP) times on respiratory mechanics and arterial gases of surgical patients when ventilated under an open lung approach (OLA) strategy. The investigators evaluate the impact of using EIP 10% versus 30% of the inspiratory time on a volume control model. The investigators also analyse the potential influence of these EIP on pulmonary gas distribution measured by electric impedance tomography.

Critically ill patients may need support for breathing by means of intubation, which is placement of a breathing tube into the windpipe. Rapid sequence intubation (RSI) is a method commonly used and is performed by administering medications to induce coma and muscle paralysis, followed by intubation to allow the ventilator to provide oxygen into the lungs. This procedure may be filled with potential complications. During RSI, the patient stops spontaneous breathing after medically induced muscle paralysis occurs. Adequate oxygenation before and during paralysis is crucial to increase the reserves and prolong the time that oxygen levels in the blood remain above 90%, called the safe apnoea period. If the oxygen reserves are insufficient, the blood oxygen level will drop and can lead to permanent brain damage or even death. This study aims to explore if delivering high-flow humidified oxygen at 60L/min via the nostrils would be superior to current methods of mask ventilation at 15L/min and nasal cannula at 15L/min, before and during paralysis respectively. If successful, this new method would allow for a longer safe apnoeic period and increase the chances for doctors to perform intubation successfully without the blood oxygen dropping below 90%.

The aim of this study is to investigate the effective of inspiratory muscle training on respiratory function, exercise capacity, physical activity and quality of life.
