Effect Analyse Of Ultrasound-guided Stellate Ganglion Block On Sudden Deafness

ObjectiveTo explore the value of ultrasound in the treatment of sudden deafness by stellate ganglion block.It provides a reference for ultrasound guided nerve block and other operations widely applied in clinical work.MethodsA total of 48 cases of sudden deafness(unilateral onset)diagnosed in our hospital in October 2015-January 2017 were randomly divided into ultrasound group(n=24)and control group(n=24).Inclusion criteria:(1)In line with diagnostic criteria for sudden deafness established by the Editorial Committee of the Chinese Journal of Otolaryngology and head and neck surgery and the Chinese Medical Association of Otorhinolaryngology Head and neck surgery branch;(2)Course of disease less than equal to or equal to 14 days;(3)Unilateral onset.Exclusion criteria:(1)Acoustic immittance measurement,vestibular function examination and MRI of brain prompt organic lesions;(2)Combined with hemorrhagic disease or cardiac insufficiency;(3)Severe mental disorders can not cooperate with the treatment of disease.In the ultrasound group,the ultrasound guided stellate ganglion block was used and in the control group,the traditional blind method was used to treat sudden dcafness.The total effective rate,the success rate of blockage and the incidence of adverse reactions in the two groups were analyzed.Results(1)Average hearing threshold:the average hearing threshold before treatment of the two groups had no statistically significant difference(P>0.05);10 days after treatment,1 months after treatment,3 months after treatment,6 months after treatment,average thresholds of two groups were lower than those before treatment,and the ultrasound group was lower than the control group,and the differences were statistically significant(P<0.05).But there was no significant differences between 1 months after treatment,3 months after treatment,6 months after treatment and 10 days after treatment(P>0.05).(2)Clinical efficacy:the total effective rate of ultrasound group(95.83%)was higher than that of the control group(62.5%),and the difference between the two groups was statistically significant(P<0.05).(3)Block success rate:the ultrasonic group(98.75%)was significantly higher than that of the control group(77.92%),and the difference was statistically significant(P<0.05).(4)Adverse reaction:the incidence of recurrent laryngeal nerve block were 0.83%and 6.25%;brachial plexus block incidence rate were 0.83%and 4.17%;local anesthetics poisoning incidence rate were 0.42%and 2.08%;the total adverse reaction rates were 2.08%and 12.50%,indexes of the two groups above were statistically significant(P<0.05).ConclusionsThe effect of ultrasonic guided stellate ganglion block on sudden deafness is more obvious than the traditional blind method,the success rate of block is higher,the incidence of adverse reaction is lower,and it is more safe.
