Comparison of epidural ropivacaine and ropivacaine clonidine combination for elective cesarean sections.

The high cephalic spread of ropivacaine analgesia may be significant but still its quality may not correlate with the level of sensory analgesia.[ 13 ] The addition of clonidine as an adjuvant allows a lesser dose of ropivacaine when used intrathecally for cesarean section.[ 14 ] Clonidine augments the action of local anesthetics in regional blockades by interrupting the neural transmission of painful stimuli in Aδ and C fibres as well as augments the blockade of local anesthetic agents by increasing the conductance of K + ions in nerve fibres.
