N2  - Twenty women in labor were located to receive either a continuous epidural infusion of 0.125% bupivacaine at a rate 8-10 ml/hr or hourly intermittent injections of bupivacaine 0.125%. Both groups received an initial bolus dose of 8-10 ml bupivacaine 0.125% . Supplementary top-up doses of 4-5 ml bupivacaine 0.15% were given when the pain scores failed to change in the subsequent hour. Results showed that both groups attained comparable best pain scores (p>0.37), but more patients from the intermittent injection group suffered worst pain scores(p=0.0704). The infusion group has a significantly shortened active stage of labor (p<0.1) and used less total volume of bupivacaine 0.125%(p<0.001). Sixty percent of the intermittent injection group required top-up doses. Likewise, there was a greater incidence of motor block in this group (p=0.016). Instrumental delivery was not needed for both groups. 2/10*20%) belonging to the intermittent injection group reported pain on episiotomy, episiorrhaphy and delivery
