Clinical equivalence of Trusynth fast® and Vicryl rapide® polyglactin 910 fast absorbing sutures on maternal morbidity experienced by women following episiotomy repair: a single-blind, randomized study

Abstract

Background: Episiotomy procedure enlarges the vaginal outlet to facilitate childbirth. Polyglactin 910 fast-absorbing sutures are widely used for the repair of episiotomy because of their rapid absorption and less inflammatory response. This study was designed for subjective assessment of perineal pain post-episiotomy repair, with Trusynth Fast® and Vicryl Rapide® polyglactin 910 fast-absorbing sutures. Method: This was a single-blind, randomized, prospective study conducted between January 7, 2021 and July 14, 2021 across two centers in India. Primiparous or multiparous women (18—40 years), who required episiotomy during vaginal delivery were included, and either Trusynth Fast® (n=47) or Vicryl Rapide® (n=49) suture was used for their episiotomy repair. The primary endpoint, perineal pain was assessed with visual analogue scale at all follow-up visits. The secondary endpoints, quantity of local anesthesia, number of sutures used, time to repair episiotomy, intraoperative suture handling, analgesics used, early and late wound complications, wound re-suturing, time to complete healing, presence of residual sutures, return to sexual activity, dyspareunia, and adverse events were also recorded. Results: The study showed no significant difference in perineal pain between the two groups at any visit. A statistically significant difference (p<0.05) in total score of episiotomy healing scale on day 2 (0.13±0.34 versus 0.35±0.56) and swelling on day 2 (8.51 versusversus 28.57%) was noted between Trusynth Fast® and Vicryl Rapide® group. Non-significant difference was observed between the groups regarding anesthesia, number of sutures, time to repair episiotomy, intraoperative suture handling, analgesics, puerperal fever, wound infection, dehiscence, hematoma, urinary incontinence, re-suturing, time to complete healing, return to sexual activity and dyspareunia. Conclusion: Trusynth Fast® suture is clinically equivalent to Vicryl Rapide® suture and can be used for episiotomy repair with minimal risk of perineal pain and wound complications.
