A Review of Episiotomy and Modalities for Relief of Episiotomy Pain

Episiotomy is a surgically planned incision of the perineum and the posterior vaginal wall in the second stage of labour. It is one of the most commonly performed surgical procedures in the world. In episiotomy, the vaginal orifice is made larger to facilitate the birth of a baby. The postnatal period is very crucial in every mother's life, especially those who had a vaginal delivery and underwent episiotomy. Maternal benefits of episiotomy include reduced risk of perineal trauma, subsequent pelvic floor dysfunction and prolapse, urinary incontinence, faecal incontinence, and sexual dysfunction. Potential benefits for the foetus are thought to include a shortened second stage of labour. However, an episiotomy can also lead to potential adverse consequences, including the extension to a third- or fourth-degree tear, anal sphincter dysfunction, and dyspareunia. Different approaches can be adopted to reduce these complications in the postpartum period, including cleanliness, cold packs, sitz baths, kegel exercises, perineal care, and topical application of dry heat-infrared lamp therapy. Of all these approaches, infrared lamp therapy and sitz baths are the two most effective and commonly used for episiotomy pain relief and wound healing. In infrared lamp therapy, radiant heat or infrared rays are used to produce heat that is then applied to the episiotomy wound to facilitate pain relief and wound healing, while a sitz bath is a moist heat application process that is also effective for episiotomy pain relief and wound healing. This review aims to offer the most thorough understanding of episiotomy, its current concept, and episiotomy pain relief, with a particular focus on infrared lamp therapy and sitz baths.
