Perineal care.
BACKGROUND
More than 85% of women having a vaginal birth suffer some perineal trauma. Spontaneous tears requiring suturing are estimated to occur in at least one third of women in the UK and US. Perineal trauma can lead to long-term physical and psychological problems.


METHODS
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of different methods and materials for primary repair of first- and second-degree tears and episiotomies? What are the effects of different methods and materials for primary repair of obstetric anal sphincter injuries (third- and fourth-degree tears)? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2013 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).


RESULTS
We found 33 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.


CONCLUSIONS
In this systematic review, we present information relating to the effectiveness and safety of the following interventions: conventional suturing; different methods and materials for primary repair of obstetric anal sphincter injuries; non-suturing of muscle and skin (or perineal skin alone); and sutures (absorbable synthetic sutures, catgut sutures, continuous sutures, interrupted sutures).
