Painless delivery – a short experience
Maharjan SK and Karki CB
Abstract: Purpose: To determine efficacy and safety a randomized comparison of continuous infusion versus intermittent
injection of epidural bupivacaine for labor analgesia was performed in the Maternity Hospital, Thapathali
Kathmandu. Methods: Twenty healthy parturient received a loading dose of 10 ml of epidural 0.1% bupivacaine
with 25 mg of pethidine. They were then randomized to receive continuous infusion of 0.1% bupivacaine 10 ml/hour
with the help of infusion pump or intermittent injection of 0.1% bupivacaine 10 ml hourly. For breakthrough pain 10
ml of 0.1% bupivacaine top ups given in both groups. The two groups were compared for analgesic efficacy, mode
of delivery, patient assessment of analgesia, motor block and other complications. Data analyzed in Pentium III
version with SPSS and statistical significance test is done with independent samples t-test. Results: The 10 patients
in each group were comparable in age but not in parity. Analgesic efficacy was excellent in 10 cases and
comfortable in another 10 cases [excellent / comfortable 6:4 with infusion and 4:6 with intermittent injection]. There
were no statistically significant differences between groups in pain scores or duration of active first or second stage
of labor. Fifteen women had spontaneous vaginal deliveries, one caesarian section (infusion group) and four
instrumental deliveries (intermittent injection group). Four women in the infusion group had hypotension and motor
block, but none in the intermittent injection group. APGAR scores in both groups were 7-8/10 at 1 minute and 9-
10/10 at 5 minutes. Conclusion: Both continuous infusion and intermittent injection of low dose bupivacaine are
very good methods of relieving labor pain in our context. Analgesic efficacy was similar in both groups and there
was no prolongation of second stage of labor
