Effects Of Right Stellate Ganglion Block (SGB) On The Sleep Quality Of Healthy People

Objective : To investigate the effect of right Stellate Ganglion Block(SGB)on the sleep quality of healthy people in the short term.methods:40 Volunteers with ASA I-?,aged 20-45 years old and 18.5-23.9 Kg·m-2 BMI were eligible which includes male 22 and female 18(excl.Someone with myocardial ischemia recently,angina pectoris,coronary disease,sinus arrhythmia,Atrioventricular heart-block,glaucoma,snoring,disturbances of blood coagulation or anticoagulation therapy,somnambulism,menopause,organic brain disease,mental retardation,Pineal organic lesion and other severe mental illness or drug and alcohol dependence such as bipolar affective disorder,chronic dementia).The 40 volunteers were randomly selected according to the random number table method.Firstly before the start of the study,the correlation test between the millet SPORTS BRACELET and the multi conduction sleep monitor was carried out.Secondly the main research experiment of the effect of single stellate ganglion block on the sleep quality of healthy people in short time was discussed.Volunteers are all in accordance with the order number.After enter the observation room,the ECG vital sign monitoring was given.The right stellate ganglion block(SGB)with 0.2% ropivacaine in 4ml was carried under the guidance of ultrasound.Diaries were used to measure deep sleep duration and the change in the proportion of total sleep time of before SGB 7 days and after SGB 1 month(sports bracelets)..In the pilot study,patient assessments were scheduled at baseline(1 week before the SGB procedure).Efficacy data were analyzed using bivariate linear correlation analysis,the Repeated-measure ANOVA.Results: forty volunteers participated and none refused the SGB procedure.Most patients received more than one SGB and the pilot study found SGB to be safe.Millet Sports Bracelet has a good reliability.In the main study,deep sleep duration were prolonged from based and the ratio were improved from baseline,respectively.Conclusion: In one month,SGB appears to be an effective treatment with acceptable morbidity for healthy people.Although the efficacy of SGB for sleep quality was measured just for one month.Longer time and more than one SGB are needed to confirm these findings.
