Clinical practices in the management and follow-up of obstetric anal sphincter injuries: a comprehensive review

Objectives

To review and compare existing guidelines on the intrapartum management and postpartum follow-up of obstetric anal sphincter injuries (OASIS)

Methods

We conducted a systematic review of clinical guidelines related to OASIS management, focusing on intrapartum care and postpartum follow-up. Searches were performed in July 2024 across multiple databases, including PubMed, Embase, and the Cochrane Library. Guidelines published after 2010 in English were included.

Results

Nine national guidelines were included. There was a consensus on OASIS classification and immediate management, particularly regarding suture techniques, materials, and the necessity of adequate analgesia. However, notable variations were identified in the timing of repair, specialist involvement, use of prophylactic antibiotics, and post-operative care protocols. Postpartum follow-up practices also varied, especially regarding the role of physiotherapy and the timing of specialist consultations, reflecting inconsistencies in long-term care recommendations.

Conclusion

Significant variability existed in the guidelines for the management and follow-up of OASIS, particularly in postpartum care. This study underscored the need for standardized, evidence-based guidelines to ensure consistent and optimal care for women affected by OASIS.
