| description | <p>Abstract</p> <p>Background</p> <p>Potentiating the effect of intrathecal local anesthetics by addition of intrathecal opiods for intra-abdominal surgeries is known. In this study by addition of fentanyl we tried to minimize the dose of bupivacaine, thereby reducing the side effects caused by higher doses of intrathecal bupivacaine in cesarean section.</p> <p>Methods</p> <p>Study was performed on 120 cesarean section parturients divided into six groups, identified as B<sub>8</sub>, B<sub>10 </sub>and B <sub>12.5 </sub>8.10 and 12.5 mg of bupivacaine mg and FB<sub>8</sub>, FB<sub>10 </sub>and FB <sub>12.5 </sub>received a combination of 12.5 μg intrathecal fentanyl respectively.

Alone lower concentrations of bupivacaine could not complete removed the visceral pain. Blood pressure declined with the increasing concentration of Bupivacaine and Fentanyl. Incidence of nausea and shivering reduces significantly whereas, the postoperative pain relief and hemodynamics increased by adding fentanyl.
