Abstract:Objective To explore the clinical efficacy of different concentrations of ropivacaine in stellate ganglion block combined with abdominal acupuncture in the treatment of facial paralysis. Methods A total of 120 patients with acute peripheral facial paralysis admitted to the Second Affiliated Hospital of Hebei North University from May 2019 to March 2021 were divided into control group and observation group by random number table,with 60 cases in each group.A total of 111 patients were included in the final study, except for those who were interrupted the study, transferred to other hospital and lacked clinical data due to various reasons. There were 59 cases in the control group and 52 cases in the observation group. Patients in both groups were given the same drug treatment (intravenous infusion of acyclovir for 7 days, oral administration of mecobalamin tablets for 21 days) and abdominal acupuncture therapy (once a day, 7 days per course, for 3 consecutive courses); On this basis, the control group and the observation group were given 0.15% and 0.25% ropivacaine for stellate ganglion block, respectively(both once a day, alternating left and right, 7 days as a course of treatment, and then the second course of treatment after 7 days rest). The clinical efficacy, the duration of ropivacaine effect, the facial nerve function score and adverse reactions before treatment, 7 d and 21 d after treatment were compared between two groups. Results After two courses of stellate ganglion block treatment, compared with the control group, the observation group had higher clinical efficacy and longer duration of ropivacaine action, with a statistically significant difference（P＜0.05）. Compared with the control group, the neurological function scores of the observation group was higher after 7 d and 21 d of treatment（P＜0.05）. There was no significant difference in the total incidence of adverse reactions between the two groups（3.39% vs 5.77%， χ²=0.021， P=0.885）. Conclusion The treatment of faical paralysis with 0.25% concentration of ropivacaine in stellate ganglion block can effectively prolong the action time of ropivacaine, effectively promote the improvement of facial paralysis symptoms and facial nerve function. There is no obvious adverse reaction during the treatment, and the safety is guaranteed.
