Postpartum management of perineal injury - A critical narrative review of level 1 evidence

Abstract

BackgroundInjury to the perineum is a common sequalae of vaginal birth. Lack of appropriateperineal wound care in the postnatal period is associated with increased pain and morbidity in theshort, medium, and long term. Women and maternity healthcare providers require high-levelevidence-based information to inform postnatal perineal wound care. ObjectivesTo review the high-level evidence informing postpartum management of perineal trauma. DesignA systematic search of the literature regarding the postnatal management of perineal injury to produce a critical narrative review of the available level I evidence regarding the postnatal management of perineal trauma up to six months postpartum was undertaken. Systematic reviews were identified from searching the following databases: CINAHL, Cochrane Library, MEDLINE, PUBMED, and SCOPUS. Papers were selected if they met the following criteria: systematic reviews/level I evidence related to postnatal management of any form of perineal injury up to six months post birth, written in English, and published from January 2010 to 30th May 2021. A synthesis of the results was developed. FindingsNineteen systematic reviews met criteria for inclusion. The systematic reviews fell into one of the following categories of perineal trauma management: use of medication for pain relief, the decision to suture, suture techniques/materials, cryotherapy, use of antibiotics, ultrasound, physiotherapy treatment and complementary therapies. Conclusion: There is an overall lack of focused high-quality research to inform management of perineal injuries beyond the acute postnatal period. Clinical trials that include women’s satisfaction and wellbeing as outcome measures are limited. Implications for practiceIt is vital that women are provided with evidence-based postnatal care strategies to enhance perineal healing and resumption of normal activities. Future clinical trials for the management of perineal trauma should incorporate women’s satisfaction as an outcome measure.Further research examining the follow-up care for the medium-long term for women experiencing ongoing sequalae of symptoms in the community setting is required to support clinical practice recommendations.
