Clinical Trial Summary
Perineal trauma at the time of vaginal delivery is common, and when the anal sphincter is
included, these injuries can be associated with additional morbidity including incontinence,
pelvic pain and sexual dysfunction. Techniques studied include hands-on vs hands-off,
perineal massage, warm compresses, Ritgen maneuver, and others. It is unclear if a hands-on
technique decreases the incidence of perineal trauma compared to a hands-off technique
Description:
Different strategies have been adopted in the late first and/or second stage of labor to
decrease the incidence of perineal lacerations. These strategies include not only the
hands-on technique, but also warm compresses, perineal massage, the use of oil or jelly, the
Ritgen maneuver and a new perineal protection device. The review by Aasheim reported a
decreased risk of third- and fourth-degree lacerations in the perineal massage group (two
studies, RR 0.52, 95% CI 0.29 to 0.94).4 This review also showed a similar reduction in
third- and fourth-degree lacerations with warm compresses (two studies, RR 0.48, 95% CI 0.28
to 0.84), but no significant changes with use of a Ritgen maneuver. Additional reviews have
evaluated delayed versus immediate pushing, with no significant difference in perineal
trauma.
Regarding how the interventions may work, initially the hands-on technique was hypothesized
to control the velocity of the crowning process and therefore decrease perineal trauma. Given
the fact that the hands-on approach has been found to be possibly associated with more
perineal lacerations instead of less, some have proposed that the harm may be caused by the
hands-on approach's additional pressure resulting in some perineal ischemia. Moreover, using
one intervention (e.g. hands-on) may predispose to use other interventions (e.g. episiotomy),
which have themselves been proven to increase perineal trauma.
Perhaps a combination of perineal interventions, such as massage or compresses, with a
hands-off approach and avoidance of episiotomy, will prove to show improved perineal
outcomes. Larger studies, including evaluation specific for nulliparous subjects, are
required to make definitive recommendations for management.
