The Impact of Daily Sinus Irrigation on Nasal Symptoms in Continuous Positive Airway Pressure (CPAP) Users - A Pilot Study

Continuous positive airway pressure (CPAP) is the most commonly used treatment for obstructive sleep apnea. Nasal symptoms such as dryness, itching and congestion are common in CPAP users. Nasal and sinus saline irrigation has been shown to improve these symptoms in individuals with chronic nasal congestion and sinusitis. This is ...

Phase N/A

Prospective Randomized Study of Nasal High Flow in Treatment of Acute Exacerbation of Chronic Obstructive Pulmonary Disease

The main oxygen therapy to the patients with acute exacerbation of Chronic obstructive pulmonary disease, who are mild to moderate respiratory insufficiency (arterial blood gas analysis showed pH = 7.35, PO2 < 60mmHg,PaCO245mmHg) or have achieved the traditional noninvasive ventilation support standard but can not tolerate or reject, was nasal ...

Phase N/A

Endo-nasal Endoscopic DCR and External-DCR in Primary Nasolacrimal Duct Obstruction

All patients with epiphora or eye discharge that admitted to our ophthalmic plastic clinic in Farabi hospital will be systemically evaluated. Those with confirmed diagnosis of primary nasolacrimal duct obstruction (PANDO) that need DCR by one senior ophthalmic plastic consultant, will be randomly assigned to one of the 2 treatment ...

Phase N/A

Effect of CPAP and Adenotonsillectomy in Upper Airway Volume of Children With OSAS

The obstructive sleep apnea syndrome (OSAS) is defined as recurrent events of obstruction of the upper airway (with alteration of normal oxygenation, ventilation or sleep pattern). In children originates complications such as cognitive, cardiovascular and metabolic disorders and growth failure, which make its management imperative. It has a reported prevalence ...

Phase N/A

Comparison of High Flow Nasal Cannula Therapy to Nasal Oxygen as a Treatment for Obstructive Sleep Apnea in Infants

The current standard of care for treating OSA in infants less than 6 months and frequently up to 12 months of age is with a continuous flow of oxygen by nasal cannula. This is generally referred to as nasal continuous positive airway pressure or NCPAP. A nasal cannula is used ...

Phase N/A

A New Treatment for Mechanical Nasal Obstruction

Background Restricted nasal breathing is a common complaint among patients presenting to Otolaryngology clinics. In fact, one in eight people experiences some degree of nasal obstruction, or regular difficulty breathing through the nose, which is often the result of a narrowing or collapse of the internal nasal valve. This condition ...

Phase N/A

The Outcome of CPAP Titration Under Sleep Endoscopy

This is the study entitled "The outcome of CPAP titration under sleep endoscopy: A randomized controlled crossover trial". CPAP is first line golden standard treatment for Obstructive sleep apnea (OSA). However, the overall CPAP compliance is about 50%. One of the reasons responsible for the poor compliance is the inadequate ...

Phase N/A

High-Flow Nasal Oxygen Therapy for Exacerbation of Chronic Pulmonary Obstructive Disease.

As soon as admission to the intensive care unit, eligible patients who gave consent will be randomized to either HFNO or Noninvasive ventilation therapy for at least the first 24 hours. In the usual care group , Noninvasive ventilation will be applied in alternance with standard nasal oxygen therapy. In ...

Phase N/A

High Flow Nasal Cannula vs NPPV in Moderate Chronic Obstructive Pulmonary Disease Exacerbation

Recently, many clinical studies have showed that HFNC can be successfully used in patients with hypoxemic respiratory failure to improve the comfort, to attenuate respiratory failure and to decrease the rate of tracheal intubation and mortality. Although theoretically HFNC is a potential and ideal treatment for AECOPD patients, the related ...

Phase N/A

Effect of Oxymetazoline Hydrochloride in Combination With Fluticasone Propionate on the Apnea Hypopnea Index (AHI) in Subject With Persistent Nasal Congestion and Mild Obstructive Sleep Apnea

To evaluate the effectiveness of the addition of intranasal oxymetazoline to ongoing optimal doses of intranasal fluticasone propionate on the apnea/hypopnea index (AHI) in subjects with persistent nasal congestion and mild obstructive sleep apnea secondary to perennial allergic or non-allergic rhinitis despite treatment with the recommended doses of NGCS. The ...
