In order to assess a method which could prevent this problem, the present study was conducted to investigate the effect of the systemic opioid on the spinal anesthesia with local anesthetic. In this study 118 ASA-I, II patients were allocated randomly to two groups. In group 1 spinal anesthesia was induced with bupivacaine 0.5% and after fixation of the analgesia level, Sufentanil 10μg was injected intravenously and ten minutes later the analgesia level was tested again and recorded. In the second group, intravenous normal saline 2ml was injected instead of sufentanil. The results showed that in all subjects of the first group the level of analgesia enhanced whereas this was not the case in the second group. M3 ER -
