Q

How does sleep restriction work?

A

Restrict time in bed to improve sleep depth & consolidation

Determine average time asleep based on baseline sleep diary
Set time in bed = time asleep
Consistent wake-up time
No daytime naps
If time asleep > 85% of time in bed then increase time in bed (15-20 minutes)
If time asleep < 80% of time in bed then decrease time in bed (15-20 minutes)
Time in bed increases continue as long as sleep efficiency > 85% until patient reports optimal daytime functioning

blurred vision, excitability and cardiac arrhythmias.

50
Q

A

The FDA has also warned that kava may be linked to serious liver damage and in addition should not be used by persons with cardiovascular disease.

51
Q

What are the sleep architecture effects of Clomipramine

A

Clomipramine, a tricyclic antidepressant, is one of the most potent REM suppressing drugs available. Other tricyclic drugs and SSRIs tend to cause a more modest suppression of REM sleep.

52
Q

What are the sleep architecture effects of Trazodone and nefazodone

A

Trazodone and nefazodone have fewer effects on REM, and some reports have even shown an increase in REM sleep. In general, antidepressants have few effects on slow wave sleep. However, tertiary tricyclic antidepressants and trazodone have been found to increase slow wave sleep in some studies.

53
Q

Can benzodiazepines help PAP Therapy

A

benzodiazepines may be of benefit in promoting sleep and improving tolerance of PAP. Non-benzodiazepine benzodiazepine receptor agonists such as zolpidem and eszopiclone do not affect obstructive sleep apnea AHI or SpO2. Multiple studies show improved adherence to PAP therapy when the patient is concurrently initiated on a Non-benzodiazepine benzodiazepine receptor agonists.

54
Q

What are the side effects of zolpidem

A

The most common side effects of zolpidem may include nausea, dizziness, malaise, nightmares, agitation, headaches.Do not see rebound insomnia between nights of treatment and drug-free nights. Zolpidem as-needed administration may allow patients to adapt treatment to their needs and to the evolution of their insomnia.

55
Q

Where the effect sizes of benzodiazepines for sleep.

A

The effect of benzodiazepine receptor agonists versus placebo was measured as the effect size d, which is a standardized measure of the difference between active treatment and placebo. By convention, effect sizes below 0.5 are considered small, between 0.5 and 0.8 moderate, and above 0.8 large. On measures of self-reported sleep latency, total sleep time (TST), number of awakenings, and sleep quality, benzodiazepine receptor showed a consistently superior effects to placebo. The effect sizes were moderately large, demonstrating that these drugs are indeed efficacious for short-term treatment.

56
Q

Describe the effects of sleep restriction

A

Sleep Restriction Therapy is designed to consolidate sleep by increasing sleep drive. The technique involves an initial reduction in the time spent in bed followed by a gradual extension of time in bed, The patient is initially prescribed a time-in-bed period that is roughly equal in length to the total amount of sleep reported on baseline sleep diaries. The actual placement of the sleep period should be determined based on the patient’s circadian rhythm preference and specific life constraints. The minimum time in bed recommended is 5 hours nightly. When sleep efficiency is at least 85% on average for approximately 1 week, the time in bed is increased by 15-20 minutes if the patient reports adverse daytime consequences. Increases in time spent in bed continue in 15-20 minute increments per week, as long as the sleep efficiency remains above 85% When sleep efficiency drops below 80%, time-in-bed is decreased by 15-20 minutes until sleep efficiency increases above 85%.
