Adenotonsillectomy for Obstructive Sleep-Disordered Breathing in Childhood:The Chania Community...
Sleep Disordered BreathingObstructive Sleep Apnea3 moreObstructive sleep-disordered breathing (SDB) in childhood is a disorder of breathing during sleep characterized by intermittent upper airway obstruction. Snoring, labored breathing and apneas reported by the parents are the most frequent symptoms.Obstructive SDB can result from many different abnormalities including large adenoids and tonsils or obesity. Intermittent upper airway obstruction during sleep is accompanied by low oxygen or high carbon dioxide in the blood and arousals from sleep. If obstructive SDB is not treated, complications may develop such as: i) enuresis; ii) delay in somatic growth rate; iii) central nervous system morbidity (e.g. hyperactivity and learning difficulties); and iv) elevated blood pressure. Overnight polysomnography (PSG) is considered the gold-standard method for defining severity of obstructive SDB and subgroups of children with snoring who should be treated. However, PSG is a labor-intensive, time-consuming and expensive diagnostic method, which is not available in many community settings. Thus, there is an urgent need for developing easy-to-use and low-cost diagnostic methods which can be used to determine severity of obstructive SDB and define subgroups of children with snoring and large adenoids and tonsils who will benefit from adenotonsillectomy (AT). Pulse oximetry is a widely available, non-invasive method which allows continuous monitoring of oxygen transport by hemoglobin. Episodes of upper airway obstruction are frequently accompanied by reductions in the hemoglobin oxygen transport (oxygen desaturation of hemoglobin).The hypothesis of this research project is that subgroups of children with snoring and adenotonsillar hypertrophy and certain abnormalities in oxygenation detected by nocturnal pulse oximetry will benefit from AT in a community setting.
Resistive Inspiratory Manoeuvre as Airway Clearance Technique in Cystic Fibrosis
Cystic FibrosisThis trial aims to analyze whether the resistive inspiratory manoeuvre (RIM) performed previously to autogenic drainage (AD) technique improves the effectiveness in terms of mucus clearance during a typical bronchial drainage session in adults, stable CF patients.
Effects of Deep Breathing Exercises Two Months After Cardiac Surgery
CABGValve SurgeryHypothesis: Deep breathing exercises performed during the first two months after cardiac surgery, will improve pulmonary function and patient-perceived quality of recovery. Specific aim: To evaluate the effectiveness of breathing exercises performed with a mechanical device for positive expiratory pressure during the first two months after cardiac surgery compared to a control group performing no breathing exercises. Design: A prospective, randomized, controlled two-center study.
Treatment of Sleep Related Breathing Disorders in Patients With Pulmonary Hypertension
Pulmonary HypertensionBreathing-Related Sleep DisorderThe purpose of this study is to study the differential short-term effect of nocturnal oxygen, acetazolamide tablets and nocturnal non-invasive positive pressure ventilation on symptoms, exercise capacity and nocturnal breathing disturbances in subjects with pulmonary hypertension and sleep related breathing disorders Trial with medicinal product
Effects of Inspiratory Muscle Training in COPD
COPDInspiratory Muscle WeaknessThe additional effect of inspiratory muscle training as an adjunct to a general exercise training program in patients with COPD with inspiratory muscle weakness will be studied. The main hypothesis is that inspiratory muscle training combined with an exercise training program improves functional exercise capacity more than an exercise training program without the addition of an inspiratory muscle training program.
Treatment of Predominant Central Sleep Apnoea by Adaptive Servo Ventilation in Patients With Heart...
Heart FailureSleep Disordered BreathingThe purpose of this trial is to evaluate the long-term effects and cost-effectiveness of adaptive servo-ventilation (ASV) on the mortality and morbidity of patients with stable heart failure due to left ventricular systolic dysfunction, already receiving optimal medical therapy, who have sleep disordered breathing (SDB) that is predominantly central sleep apnea. Assumptions: the intervention reduces the hazard rate by 20%. The event rate in the control group is 35% in the first year. It is assumed that the hazard rate is constant over time.
A Trial to Determine How Long Insulin and FDKP (the Molecule That Forms Technosphere Particles)...
Healthy SubjectsLavage fluid (BAL) is inserted into a lung lobe using a flexible bronchoscope. The fluid is aspirated out to remove any remaining TI. It's performed twice at specific time points in 12 healthy volunteers. BAL fluid will be analyzed for insulin and FDKP.
Safety and Efficacy Study of Ciprofloxacin for Inhalation in Patients With Non-Cystic Fibrosis Bronchiectasis...
Non-Cystic Fibrosis BronchiectasisThe purpose of this study is to evaluate the safety and efficacy of Ciprofloxacin for Inhalation in the treatment of patients with non-cystic fibrosis (CF) bronchiectasis.
A Study of Tobramycin Inhalation Powder From a Modified Manufacturing Process Versus Placebo
Cystic FibrosisThis study is designed to show how well tobramycin inhalation powder works and how safe it is when produced by a modified manufacturing process
Comparison of Modified With Conventional Adaptive Servoventilation Processes
Periodic BreathingCheyne-Stokes RespirationThe objective of this study is to compare the modified adaptive servoventilation control algorithm of the with the standardised algorithms of routinely-used servoventilation processes (AutoSet CS2) in terms of the effect on obstructive and central events. The aim is to normalise breathing during sleep and hence eliminate the sleep-related breathing disorder, resulting in even more effective treatment of nocturnal breathing disorders in patients with cardiovascular diseases and sleep apnoea, to ensure optimum therapy success.
