Efficacy of Oral Appliances on Obstructive Sleep Apnea During Pregnancy
- Conditions
- Sleep Apnea, ObstructivePregnancy Related
- Interventions
- Device: Somnodent
- Registration Number
- NCT03138291
- Lead Sponsor
- Université de Montréal
- Brief Summary
Issue: The prevalence and severity of sleep-disordered breathing increases during pregnancy due to weight gain, physiological and hormonal changes. These sleep breathing disorders have a negative impact on perinatal health for both the mother and the child.The optimal treatment of obstructive sleep apnea in pregnancy is unknown. Although CPAP therapy is often the treatment of choice, the mandibular advancement appliance would be an interesting alternative to solve the matter.
Objectives: The main objective of this pilot study is to evaluate the feasibility of mandibular advancement device to treat sleep apnea during the 2nd and 3rd trimesters of pregnancy. Secondary objectives will be tools to plan a future randomized controlled trial to determine the efficacy of this treatment.
- Detailed Description
Study design : Intervention Pilot Study uncontrolled experimental cohort
Population: 32 pregnant women with sleep apnea with an apnea - hypopnea index ( AHI ) ≥ 10 events / hr .
Methodology: The mandibular advancement appliance will be used with the chip DentiTracs to measure adhesion. Participation in this project requires five visits to the research team, including 3 visits at home. Participants will be recruited and granted in obstetrics MUHC. The questionnaires will be filled (Epworth Sleepiness Scale, Pittsburgh sleep quality and functional (FOSQ)). A sleep recording (PSG type II) will be done at home to confirm the diagnosis. The recording equipment will be returned to the research team by mail. During the second visit (clinical orthodontics), dental impressions in alginate will be made. At the 3rd visit (clinical orthodontics), the mandibular advancement appliance will be adjusted and instructions will be given. A weekly phone call follow-up will be ensured during this period of adjustment of the appliance. The fourth visit (at home) will consist of a sleep recording to evaluate the effect of treatment. A questionnaire comfort / secondary effects will be administered. For patients who have started their participation during their second trimester, a sleep recording at home (4a visit) will be realized in Q3 to assess whether it is necessary to change the titration of the appliance. The 5th visit (orthodontic clinic) will be 3-6 months after delivery. Participants will fulfill all the mentioned questionnaires and make a sleep recording at home without the appliance. Replace the appliance in place if AHI\> 10. During the 4th and 5th visits, anthropometric data (ie, weight), and objective adhesion will be taken

Group Intervention Description Somnodent Somnodent SomnoDent is a custom-made oral appliance for the treatment of mild to moderate obstructive sleep apnea. SomnoDent is worn during sleep to provide Continuous Open Airway Therapy by moving the lower jaw slightly forward. This movement tightens the soft tissue and muscles of the upper airway, which prevents obstructive apneas while sleeping.
- Primary Outcome Measures
Name Time Method obstructive sleep apnea 9 months Apnea hypopnea index
- Secondary Outcome Measures
Name Time Method adherence 9 months A mini-recorder will be use to see how many hours a day the patient wear the appliance.
