Detaljert beskrivelse
Objectives: The primary objective of this project is to observe the impact of stellate ganglion block (SGB) on objective measures of sleep (using a wearable headband) and subjective measures of sleep (self-report measures) in active duty service members and veterans receiving prolonged exposure therapy (PE) for PTSD. The secondary objective is to evaluate sleep improvements as a mechanism for PTSD treatment outcomes in this population.
Specific Aim 1: To compare the effects of a SGB with ropivacaine (active) versus a SGB with saline (sham) on objective measures of sleep macroarchitecture (i.e., rapid eye movement [REM] sleep and slow wave sleep) and sleep continuity (i.e., sleep onset latency, wake after sleep onset, number of awakenings, total sleep time, and sleep efficiency).
Specific Aim 2: To compare the effects of SGB (active)+PE versus SGB (sham)+PE on sleep microarchitectural indicators of heightened central nervous system arousal (i. e., high-frequency and low-frequency power spectral density, frequency of occipital alpha-indexed micro-arousals, slow wave features [e.g., slope, density] during N3 sleep, proportion of phasic and tonic REM sleep and REM density during REM sleep).
Specific Aim 3: Specific Aim 3: To evaluate the effects of SGB (active)+PE versus SGB (sham)+PE on self-reported measures of insomnia and nightmares.

|---|---|
|
Massed Prolonged Exposure (PE) with SGB group
Participants will wear the EEG headband monitoring device (Sleep Profiler)for 3 nights as a baseline prior to SGB injection administered as part of enrollment in original study from which they were recruited.
After the SGB injection, participants will wear the headband monitoring device for 3 nights.
|
The headband is worn for 3 nights prior to injection and then for a an additional 3 nights after the injection.
Efficacy of the headband is not being tested, it is used as a measuring tool.

Massed PE Exposure with Sham SGB
Participants will wear the EEG headband monitoring device (Sleep Profiler) for 3 nights as a baseline prior to the sham SGB injection administered as part of enrollment in original study from which they were recruited.
Participants will wear the EEG headband monitoring device for 3 nights following the sham SGB injection.

Insomnia Severity Index
Tidsramme: Baseline to 1 month
|
7-item self-report measure that assesses perceived severity of insomnia.
Each item uses a 4-point Likert type scale from 0 to 4. The items sum to produce a total score (range 0 - 28) with a higher score indicating

Nightmare Disorder Index (NDI)
Tidsramme: Baseline to 1 month
|
The 5-item NDI evaluates for nightmare disorder in accordance with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria. Items are scored from 0-4 to give a total range between 0-20. Higher scores on the NDI indicate greater nightmare severity. |

Split Week Self-Assessment of Sleep Survey (SASS-Y) for Workdays
Tidsramme: Baseline to 1 month
|
The Split Week SASS (SASS-Y) is a retrospective measure that assesses sleep parameters similar to a sleep diary including time to bed, number of awakenings, time of final awakening, and time out of bed, etc.
The Split Week version asks participants to estimate these parameters based on workdays.
