From ACOG: Lacerations are common after va**nal birth. Trauma can occur on the cervix, va**na, and v***a, including the labial, periclitoral, and periurethral regions, and the perineum. Most of these lacerations do not result in adverse functional outcomes. Severe perineal lacerations, extending into or through the a**l sphincter complex, although less frequent, are more commonly associated with increased risk of pelvic floor injury, f***l and urinary incontinence, pain, and sexual dysfunction with symptoms that may persist or be present many years after giving birth. What are prevention strategies for severe obstetric lacerations? Manual perineal support at delivery is commonly practiced (with health care providers in some parts of the world describing this as a “hands on” method), with several different techniques described globally. Among these are the flexion techniques and the Ritgen maneuver (or a modification of either). Because application of warm perineal compresses during pushing reduces the incidence of third-degree and fourth-degree lacerations, obstetrician–gynecologists and other obstetric care providers can apply warm compresses to the perineum during pushing to reduce the risk of perineal trauma. In a meta-a**lysis of 22 trials (7,280 subjects), upright or lateral birth positions compared with supine or lithotomy positions were associated with fewer episiotomies and operative deliveries, but higher rates of second-degree lacerations, and the overall quality of the studies was rated as low. In a recent randomized trial, lateral birthing position with delayed pushing was compared with lithotomy positions and pushing at complete dilatation in subjects with epidural anesthesia and found that subjects in the lateral position with delayed pushing were more likely to deliver with an intact perineum (40% versus 12%, P
