Perineal Warm Compresses During the Second Stage of Labour Decrease Incidence and Degree of Perineal Laceration in Primiparous

摘要

Women during their first vaginal birth commonly get perineal trauma, induced by spontaneous laceration and episiotomy. Perineal warm compresses during the second stage of labour have been shown to decrease risk of perineal laceration or the need for episiotomy in primiparous, but the role between perineal body length with incidence and degree of perineal laceration is still in debate. The aim of this study was to evaluate correlation between perineal warm compresses and perineal body length during the second stage with incidence and degree of perineal laceration in primiparous. Methods: It was a nonrandomized controlled trial conducted at teaching hospital of Department of Obstetrics & Gynecology, Hasanuddin University from January to May 2018. There were 62 samples for perineal warm compresses group and 62 samples for control group. Results: Chi-Square test showed significant correlation between perineal warm compresses during the second stage with perineal laceration incidence (p=0.030) and perineal laceration degree in primiparous (p=0.004). Perineal body length has no correlation with the incidence of perineal laceration (p=1.000) and degree of perineal laceration (p=0.149). Perineal warm compresses were effective in decreasing the degree of perineal laceration, particularly in primiparous with perineal body length of <3.3cm.
