Brief Summary
Obstructive sleep apnea (OSA) has traditionally been attributed only to a collapsible upper airway. However, it is increasingly recognized that multiple additional non-anatomical mechanisms contribute to the disease. Higher rates of OSA in patients with post-traumatic stress disorder (PTSD) than in those without PTSD have been reported however the mechanism behind this increased prevalence has not been investigated. Our hypothesis is that patients with PTSD have a predisposition to OSA due to a lower respiratory arousal threshold (wake up too easily) than patients without PTSD. The goal of this project will be to study and compare the ArTH in patients with PTSD and those without. In addition, we plan to see whether medications can be used to increase the arousal threshold and treat OSA in patients with PTSD.

Conditions
Outcome Measures
Primary Outcomes (2)
Respiratory arousal threshold
Arousal threshold will be measured by epiglottic catheter placement during routine polysomnograph. Respiratory arousal threshold is measured by standard criteria and determined by difference in the terminal pressure measured prior to cortical arousal on EEG and the baseline epiglottic pressure.
8 hours
Apnea hypopnea index
Severity of obstructive sleep apnea measured by the apnea hypopnea index. Measured by standard sleep scoring criteria.
8 hours
Study Arms (2)
Trazodone
EXPERIMENTALTo determine effect of trazodone on quality of sleep as measured by apnea hypopnea index in subjects with obstructive sleep apnea and PTSD on routine overnight polysomnogram.
Placebo
PLACEBO COMPARATORTo compare placebo outcomes against administration of trazodone
Interventions
Catheter that can be placed through the nose to a position behind the tongue to monitor for upper airway obstruction and to measure changes in pressure below the obstruction.
Eligibility Criteria
You may qualify if:
- Normal sleep study aside from elevated AHI
- Prior home sleep test (HST) or polysomnogram with results consistent with mild, moderate, or severe sleep apnea. If a sleep study has not been performed in the past, the participant will be offered an HST and included if OSA is confirmed on HST.
- PTSD as diagnosed by psychiatrist, psychologist, or other licensed mental health professional
You may not qualify if:
- Any known cardiac (apart from treated hypertension), symptomatic pulmonary (including asthma), renal, neurologic (including epilepsy), neuromuscular, or hepatic disease.
- Pregnant women.
- History of hypersensitivity to Afrin, Lidocaine, or Trazodone
- History of bleeding diathesis and/or gastrointestinal bleeding.
- Daily use of any sedative medications that may affect sleep or breathing, including benzodiazepines, opioids, or hypnotics.
- A psychiatric disorder, other than mild depression or PTSD; e.g. schizophrenia, bipolar disorder, major depression, panic or anxiety disorders.
- Substantial cigarette (\>5/day), alcohol (\>3oz/day) or use of illicit drugs.
- More than 10 cups of beverages with caffeine (coffee, tea, soda/pop) per day.
- Subjects with oxyhemoglobin desaturations to \<70% on the initial PSG (Aim 1) will be excluded from participation in Aim 2.
- Current, everyday use of continuous positive airway pressure therapy.
