The Efficiency And Safty Of Stellate Ganglion Catheter Retention Discontinuous Block On Sudden Deafness Patients

Objectives: The sudden monaural deafness patients were given the base treatment,such as Shuxuening injection, ligustrazine, vitamin B12, glucoco- rticoid,combined with hyperbaric oxygen therapy and the application of stellate ganglion catheter retention,,intermittent application of 0.1% ropivacaine block treatment.Though observation of the total efficiency of the treatment, patients satisfaction to evaluate the treatment effect.The changes of heart rate(HR), systolic blood pressure(SBP), diastolic blood pressure(DBP) and mean arterial pressure(MBP) were observed at the time point of before and after the block monitoring in patients. Wether there has tube-off, infection and drug adverse reaction to complication were observed Take this way,we evalue the safty of the technical operation.Methods:126 cases of sudden monaural deafness patients were randomly divided into three group :Catheter group, block group and control group, each group of 42 cases.All the patients were given conventional combined treatment:blood activating drugs,glucocorticosteroid and hyperbaric oxygen therapy.Catheter group application of stellate ganglion puncture retained catheter, 0.1% ropivacaine block 1 times / day;block group stellate ganglion puncture and ropivacaine block 1 times / day;The control group only used routine combined treatment. Catheter group and block group were treated first before hyperbaric oxygen therapy. Curative effects of three groups were observed.Record the changes of patients satisfaction, HR、SBP、DBP、MBP before and after the block.Record whether there is off pipe and drug adverse reaction and so on.By doing this,evaluate the safety of the treatment.Results:Catheter group,block group was better than that in control group(85.7%(37 cases), 83.3%(35 cases) vs 64.3%(27 cases), P< 0.05), The Catheter group satisfactory rate of the patients was significantly higher than that of block group(83.3%(35 cases) vs 61.9%(26 cases), P<0.05). For the Catheter group and block group for the first time, the heart rate, blood pressure before and after catheterization were changed obviously,(The heart rate(/min): 72.0±7.7 vs 94.5 ±8.3; 73.0±7.7 vs 93.0±7.9, systolic blood pressure(mm Hg, 1 mm Hg=0.133 k Pa): 122.2±12.6 vs 136.8±18.1; 123.6±11.0 vs 134.6±20.8, the mean arterial pressure(mm Hg: 96.3±17.6 vs 109.3±25.6; 95.4±15.6 vs 110.5±24.6,diastolic blood pressure(mm Hg:80.3±21.2 vs 94.7±23.8;78.5± 20.9 vs 95.1±25.6, all P<0.05),No differences between the two groups. Second~7 times before and after catheterization of the catheter group, heart rate, blood pressure did not change significantly(P>0.05),While the block group changed obviously(Heart rate(/min):73.0±8.7 vs 95.0±9.7, systolic blood pressure(mm Hg, 1 mm Hg = 0.133 k Pa): 123.7±14.0 vs 138.6±21.5, the mean arterial pressure(mm Hg):96.2±17.6 vs 112.7±25.1,diastolic blood pressure(mm Hg): 78.7±19.9 vs 96.3±23.5,all P<0.05); No drug adverse reactions and tube off events.Conclusion:1 The efficacy can be increased with 0.1% ropivacaine block cooperated by routine combined treatment:blood activating drugs,glucocorticosteroid and hyperbaric oxygen therapy,which leads to a synergic action.2 Patient satisfaction is improved with application of stellate ganglion catheter retention with discontinuous ropivacaine block.,which reduces the repeated stellate ganglion puncture pain and reduce the influence of heart rate and blood pressure in terms of puncture.3 The occurrence of no catheter prolapse and No drug adverse prove this is a safe and effective treatment method.
