Official title
Oral Appliance Therapy for Improving Sleep Quality During Pregnancy: A Controlled Clinical Trial
Overview
Many pregnant women suffer from poor sleep quality and snoring. Evidence shows an increasing association between (1) sleep disordered breathing and (2) maternal cardiovascular disease and in-hospital death. Snoring is a variant of obstructive sleep apnea (OSA) and OSA during pregnancy is associated with higher risks for cesarean delivery, gestational hypertension, preeclampsia and preterm delivery. It may also impact fetal outcomes negatively. The purpose of this study is to determine whether sleep quality can be improved in pregnant women who snore by means of an oral appliance that opens the airway. Sleep quality is evaluated objectively using an un-intrusive home sleep test system.
Detailed description
As many as 20 percent of women suffer from snoring and poor sleep quality while pregnant. The purpose of this study is to determine whether sleep can be improved in pregnant women who snore by means of a midline traction oral appliance (OA) that opens the airway. This is an interventional study to objectively evaluate OA therapy on breathing during sleep as well as its effect on sleep quality. Pregnant women from all trimesters will be recruited. Each subject is expected to participate in the study for at least five (5) consecutive weeks. Home sleep recordings will be collected at three time points: T0 - Baseline prior to OA use for two consecutive nights; T1- first two consecutive nights wearing the OA; T2 - for two consecutive nights after 4 weeks of appliance use. In addition to the sleep studies performed at each of these time points, subjects will also complete several brief surveys. All participants will be given the opportunity to use their OAs after the 4 week period, and have their sleep recorded at 8 week intervals through the remainder of their pregnancies. Participants will get to keep and use their OAs after the study.
Pregnant women who snore (or otherwise have poor sleep), may qualify to participate in this study. Those who do not want to wear an oral appliance, but are interested in learning about sleep quality while pregnant, may also qualify to participate as a control subject.
Interventions
- Device Midline traction oral appliance
Device positions the mandible forward to open airway; device can be titrated to gradually advance the mandible.
Primary outcome measures
- Ratio of stable to unstable sleep from CPC [Time frame: Two nights of sleep recordings at each of 3 time point over 5 weeks.]
Secondary outcome measures (5)
- Number of snores per hour of sleep [Time frame: At each of 3 time points over 5 weeks]
- Pittsburgh Sleep Quality Index (PSQI) [Time frame: At baseline and after 5 weeks]
- Insomnia Sleep Questionnaire (ISQ) [Time frame: At baseline and after 5 weeks]
- Hamilton Depression Rating Scale (HDRS) [Time frame: At baseline and after 5 weeks]
- Fatigue Severity Scale (FSS) [Time frame: At baseline and after 5 weeks]
