Comparison of the effect of facia iliaca block and intravenousfentanyl in reduction the pain of broken femoral shaft duringpositioning patient for spinal anesthesia

The patients with fractures of femoral shafts have severe and vigorous pain which limit their lateral positioning to perform spinal anesthesia. To detect an appropriate resolve for decreasing their pain، we decided to compare facia iliaca block and iv fentanyl injection. This study was performed as a randomized single blind sequential clinical trial. Prior to spinal anesthesia، pain score evaluated through visual analogue scale (VAS) [from 0 to 10] after that، patients randomly divided in to two groups، 10 members in each group. In the first group patients received 1. 5 mg/kg fentanyl intravenously. Once their condition was suitable to achieve the position، VAS again assessed. In second group after facia iliaca block (20ml lidocaine 2%) VAS evaluated، and then the patients positioned laterally to perform spinal anesthesia. This study showed that the time for painless lateral positioning in group fascia iliaca block was shorter than group iv fentanyl. VAS score for fascia iliaca block group was lower than iv fentanyl group. The entire information mentioned earlier was analytically significant (P<0. 05) and showed satisfactory consequences. In respect to this study، fascia iliaca block is reliable and safe and it is feasible to perform in all stages of accidents.
