About this study
Official title: Short-term Efficacy of Stellate Ganglion Block to Reduce Hot Flushes
To assess the short-term efficacy of stellate ganglion block on hot flush reduction versus sham procedure
Read the detailed description
Hot flushes are the most common symptom of menopause for which postmenopausal (PMP) women seek medical help, in 20% of PMP women hot flushes can persist for up to 15 years.
A possible treatment for hot flushes is stellate ganglion block (SGB), used as a means to interrupt parts of the sympathetic nervous system involved in temperature regulation.
Single centre randomized double blind placebo controlled intervention study Study period of 6 months in which patients will fill out on set time points 5 questionnaires regarding quality of life and keep a diary on hot flush frequency and severity during1 week on the same time points.
Study population:
Postmenopausal women aged 30-70 years old with no other causes of flushing present. Intervention (if applicable) Intervention: Stellate ganglion block versus sham procedure
Follow up with questionnaires during 6 months.

| Placebo ganglion block | Placebo comparator | Sham Nervus Sympathicus block. Stellate ganglion sham anaesthetic block using 7 ml of 0.9 % natrium chloride (NaCl) Receives: Procedure: Placebo ganglion block |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hot Flush score
Hot flush score as measured by a hot flush diary in which for each hot flush the severity is noted for one week. Severity of every flush is given on a 1-4 scale (1 is mild, 2 medium, 3 severe, and 4 is very severe)
Measured: Baseline, 4, and 8 weeks
Secondary outcomes (2)
Quality of sleep
Pittsburgh Sleep Quality Index: developed to discriminate between good and poor sleep quality. It consists of 19 individual items, creating seven components of sleep (sleep onset latency, sleep duration, sleep efficiency, sleep quality, sleep disturbances,medication, and day-time dysfunction). Each of those seven components is scored from 0 to 3. The sum of the individual scores forms the global score (0-21) of the PSQI. Lower global scores denote high sleep quality, whereas a score greater than 5 is considered poor sleep quality
Measured: Baseline, 4, and 8 weeks
Sleepiness
Epworth Sleepiness Scale. The ESS score (the sum of 8 item scores, 0-3) can range from 0 to 24. The reference range of 'normal' ESS scores is zero to 10.
Measured: Baseline, 4, and 8 weeks
