The Effect of Opening Injection Pressure Monitoring Device to Detect Needle Nerve Contact During Ultrasound Guided Popleatial Approach in Diabetic Patients for Below Knee Amputation

BACKGROUND:                                                                                                                                              Ultrasound-guided popliteal sciatic nerve blocks is a useful approach for below- knee surgery. Using the injection pressure monitoring device. OBJECTIVE: This study to assess the role of opening Injection Pressure monitoring device in providing and avoid nerve injury in patients who underwent, popliteal sciatic nerve block under ultrasound-guided.                                                                                       METHODS: This study involve fifty patients underwent unilateral below knee amputation were randomly assigned under ultrasound-guided popliteal sciatic nerve block and femoral nerve block have been done, with use opening Injection Pressure monitoring device and additional ultrasound guided. RESULTS:                                      :                                                                                        Regarding the pressure of the injections monitoring , we noticed that in this study, the highest proportion of study patients recorded needle nerve contact (44%) ,needed low pressure CONCLUSION:                                                                                                                                                There is high incidence of intraneural needle placement or needle neve  contact of nerve under ultrasound guide.
