Obstructive Sleep Apnea and Smoking Cessation Flashcards
1
Q
Obstructive Sleep Apnea
Cessation of airflow—a complete obstruction for at least 10 seconds—with a concomitant 2 to 4 percent drop in arterial oxygen saturation
Associated with
- Neurocognitive impairement
- CV effects (HTN, stroke, CHF, pulm HTN, cardiac arrhythmia)
Risk factors
- witnessed apneas
- excessive daytime sleepiness
- male gender
- BMI > 30
- Neck circumf >17” M, >16” F)
A
OSA management
Behavioral Management
- Weight loss
- Side-sleeping posture
Professional intervention
- Positive airway pressure (CPAP, APAP, BiPAP)
- Oral appliances (mandibular advancement devices, tongue retaining devices)
- Surgery
2
Q
OSA Dental Management
- Airway management (especially if sedation is used)
- Discontinue CPAP following surgery to avoid subcutaneous emphysema
- Minimize stress - increased risk for CV event
- Calcified atheromas are likely to appear more often on panoramic radiographs of patients with sleep apnea than on those of age-matched controls

Q
Smoking cessation aids
- Nicotine replacement therapy (patch, gum, lozenges, nasal spray, inhaler)
- Non-nicotine replacement therapy
- Buproprion (Zyban)
- antidepressant
- avoid in seizure pts
- Varenicline (Chantix)
- stimulates dopamine receptor
