Comparative Study of Fentanyl vs Dexmedetomidine as Adjuvants to Intrathecal Bupivacaine in Cesarean Section

The quality of the spinal anesthesia has beenreported to be improved by the addition of opioids (such as morphine, fentanyl and sufentanil) and other drugs (such as dexmedetomidine, clonidine, magnesium sulfate (Mg), neostigmine, ketamine, and midazolam). Opioids such as fentanyl in combination with bupivacaine improvesthe quality of intraoperative and early postoperative subarachnoid block. Although, fentanylensures superior quality of analgesia, it is associated with many side effects. This has directed theresearch toward the use of newer and betteradjuvants for spinal anesthesia such as clonidineand dexmedetomidine
