title: [Stellate ganglion catheter retention with discontinuous block on efficacy and safety in the treatment of sudden deafness].
abstract: OBJECTIVE
  To investigate effect and safty evaluation of stellate ganglion catheter retention with discontinuous block on sudden deafness.
  
  
  METHODS
  One hundred and twenty-six patiens with sudden monaural deafness were randomly divided into Catheterp and block and control groups with 42 cases in each group. All patients' throats were given conventional blood activating drugs, hormone and hyperbaric oxygen therapy. stellate ganglion puncture retained catheter were administrated to the patients in catheter group followed by ropivacaine block 1 times/day, block group stellate ganglion puncture and ropivacaine block 1 times/day. The patients in control group were only received routine comprehensive treatment. Patients in both catheter group and block groups were treated by hyperbaric oxygen therapy after the block treatment. Curative effects of three groups were observed. The patients' satisfaction, heart rate, the chages of blood pressure before and after the block, detachment of tubes, and adverse drug reaction were recorded.
  
  
  RESULTS
  The effect of the treatment in both catheter group, block group was better than in control group (85.7%, 37 cases); 83.3%, 35 cases) vs 64.3%, 27 cases, P < 0.05). The satisfactory rate in the patients in catheter group was significantly higher than block group (83.3%, 35 cases vs 61.9%, 26 cases, P < 0.05). The heart rate and the blood pressure before and 5 minutes after catheterization in catheter group and block groupwere changed obviously. Moreover, no adverse drug reaction and detachment of tubes were observed.
  
  
  CONCLUSIONS
  It is a safe and effective administration of stellate ganglion catheter retention with interrupted ropivacaine block.
