title: Lower limb surgeries under combined femoral and sciatic nerve block.
abstract: BACKGROUND
  Peripheral nerve blocks are gaining popularity for many infraumblical surgeries with the development of new techniques such as ultrasound and peripheral nerve stimulator. It provides stable hemodynamic, better, and prolonged postoperative analgesia. This study was carried out to see the effectiveness of combined femoral and sciatic nerve block with ropivacaine alone and by adding fentanyl.
  
  
  METHODS
  The study was carried out on 100 patients scheduled for lower limb surgeries and were randomly divided into two groups of 50 each. In Group A, patients received 20 ml of 0.5% ropivacaine for femoral nerve block and same dose for sciatic nerve block and in Group B, 25 μg fentanyl was added each for femoral nerve and sciatic nerve block along with ropivacaine. All hemodynamic parameters, onset and duration of sensory and motor blocks were noted. The patient characteristics were analyzed using the "Chi-square tests" and the intergroup comparison of the parametric data was carried out using the unpairedt-test using software IBM SPSS 17.0.
  
  
  RESULTS
  Combined femoral and sciatic nerve block provide longer duration of postoperative analgesia of about 12-13 h. All the above-mentioned parameters were statistically non-significant.
  
  
  CONCLUSIONS
  Hence in this study, onset and duration of sensory and motor block was comparable in both groups. However postoperative analgesia was prolonged as compared to neuraxial blockade without any hemodynamic instability.
