Background: Following caesarean operation, a painless early ambulation is necessary to mother for caring of the neonate. Aim of the study is to compare more effective analgesic by intrathecal bupivacaine or combination with butorphanol or dexmedetomidine.
Methods: Ninety parturients undergoing elective caesarean section were randomly divided into three equal groups (n=30). Group B: received bupivacaine (0.5%) 2 ml + 0.5 ml of normal saline (NS); group BB, bupivacaine (0.5%) 2 ml + 25 mcg butorphanol in 0.5 ml NS and group BD, bupivacaine (0.5%) 2ml + 2.5 mcg of dexmedetomidine in 0.5 ml NS . Visual numerical rating scale (VNRS), heart rate, blood pressure, sensory and motor block levels, fetal outcome by Apgar score and umbilical cord blood pH, any side effects were noted.
Results: The onset time of modified Bromage 3 motor block was statistically significant among the groups (P=0.023) but not significant between Groups BB and BD (P=0.479). The regression time to reach modified Bromage 0 in group BD was significantly longer (P=
