Objective: To compare the analgesic efficacy of Ropivacaine (0.75%) with Lignocaine (2%) in reducing the pain
of perineal tears during suturing and postpartum.
Study Design:Randomized Controlled Trial.
Place and Duration of Study: This prospective trial was conducted in Gynecology and Obstetrics department of
Kahuta Research Laboratories (KRL) hospital, Islamabad over the period of 3 months from May 2018 to August
2018
Materials and Methods: In this study 100 patients with singleton pregnancy and vertex presentation
undergoing vaginal deliveries were randomly divided into either 2% Lignocaine group or 0.75% Ropivacaine
group on the basis of subcutaneous infiltration of the corresponding local anesthetic before perineal repair.
Main outcomes studied between the 2 groups include mean pain scores assessed by Visual analogue scoring
system (VAS) at the time of suturing and then at 30 mins, 3 hours and 6 hours post partum. The need for
additional local anesthetic, on-demand analgesia and side effects were also noted. The outcomes between the
two groups were compared and analyzed by SPSS version 23.
Results: A total of 100 women were randomized and equally allocated into one of the two groups. Mean pain
score of Ropivacaine was compared with lignocaine and was found to be significantly reduced at the time of
suturing (p=0.005), 3 hours (p=0.00) and 6 hours (p=0.001) post partum. But no statistical difference was found
in pain score at 30 minutes post partum (p=0.713). The need for additional local anesthetic at suturing
(p=0.004) and need for on-demand analgesia (p=0.001) was higher in Lignocaine group. No side effects were
noted in both groups.
Conclusion: Ropivacaine was more effective in reducing post episiotomy perineal pain as compared to
lignocaine.
