Trial summary

Obstructive sleep apnea (OSA) is an increasingly prevalent disorder characterized by repeated upper airway collapse during sleep, resulting in oxygen desaturation and frequent arousals. The etiology of OSA remains unclear. Many studies indicates an association between nasal obstruction and apnea. Read more about this study

About this study

Obstructive sleep apnea (OSA) is an increasingly prevalent disorder characterized by repeated upper airway collapse during sleep, resulting in oxygen desaturation and frequent arousals. The etiology of OSA remains unclear.

Many studies indicates an association between nasal obstruction and apnea. However,the precise nature of this relationship is far from clear and the importance of resistance to nasal airflow in the pathogenesis of airway collapse in OSA patients remains contentious.

In this study, investigators perform 4 different ways to change subjective or objective patency of nasal cavity and observe the effects of the nasal airflow on nocturnal breathing, sleep,and upper airway muscles in OSA patients.

Read the detailed description
  1. All subjects underwent a standard overnight polysomnogram(PSG), including continuous genioglossal electromyography measurement , electroencephalogram, electrooculogram, electrocardiogram, nasal flow (thermister), respiratory (chest and abdominal) movements,oxy-hemoglobin saturation (pulse oximeter), and body position. Apnea event definitions and clinical classification were determined using the American Academy of Sleep Medicine(AASM) guidelines
  2. Pharyngeal electrical current sensory threshold was performed to identify the different Pharyngeal function between OSA patients and normal controls

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Oxymetazoline Nasal SprayDrug

    Obstructive sleep apnea (OSA) Patients and healthy controls were treated with 4 different nasal intervention ,including Oxymetazoline Nasal Spray,Normal saline Nasal Spray,Menthol Nasal Spray or Nasal mask with partly blocked when they sleep onset. At the treatment periods, polysomnograpy, genioglossus enlectromyography, pharyngeal current perception threshold and sleep quality scores were assess.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Apnea-hypopnea Index

    A randomized, placebo-controlled double blind study on the effects of nasal spray oxymetazoline on sleep architecture, respiratory events, body position and subjective scores in OSA patients. All participants received specific physical examinations, subjective scale assessments and a two-night polysomnography sduty (by randomly applying oxymetazoline for one night and placebo for another.).Data collected after oxymetazoline or placebo treatments were compared. Apnea-hypopnea index(AHI),defined as the sum of apneas and hypopneas per sleep hour, was used as an important indicator for assess the severity of OSA.

    Measured: 2 to 6 month

  2. Myoelectricity of genioglossus

    Participants were treated with 4 different nasal intervention ,including Oxymetazoline Nasal Spray, Normal saline Nasal Spray, Menthol Nasal Spray or Nasal mask with partly blocked when they sleep onset. At the treatment periods, subjects underwent overnight polysomnography with synchronous genioglossus electromyography . Genioglossus (GG) activations under different nasal ventilation conditions were compared.

    Measured: 2 to 6 month

  3. The pharyngeal current sensory threshold

    The pharyngeal current perception threshold test was performed before and after different nasal intervention including Oxymetazoline Nasal Spray, Normal saline Nasal Spray, Menthol Nasal Spray or Nasal mask with partly blocked different nasal cavities. Data collected from OSA patients and healthy controls were compared and analyzed.

    Measured: 2 to 6 month
