Objective:
The aim of this study is to evaluate the effect of perineal massage and warm compresses technique on the perineum integrity during second stage of labor.
Design And Setting:
A single-center, prospective, randomized controlled trial was conducted between March 1st, 2019, and December 31st, 2020, at Hospital of Braga.
Participants:
Women with 18 years or older, between 37 weeks and 41 weeks pregnant, in whom a vaginal birth of a fetus in the cephalic presentation was planned were recruited. Eight hundred forty-eight women were randomly assigned (Perineal massage and warm compresses group, n = 424 and control group, n = 424), and 800 women, both perineal massage and warm compresses group (n = 400) and control group (n = 400) were included in the strict per protocol analysis.
Intervention:
In the perineal massage and warm compresses group, women received perineal massage and warm compresses and in the control group, women received hands-on technique.
Results:
The incidence of intact perineum was significantly higher in the perineal massage and warm compresses group [perineal massage and warm compresses group: 47% vs control group: 26.3%; OR 2.53, 95% CI 1.86-3.45, p<0.001], whereas second-degree tears and episiotomy rate were significantly lower in this group [perineal massage and warm compresses group: 7.2% vs control group: 12.3%; OR 1.96, 95% CI 1.17-3.29, p = 0.010 and perineal massage and warm compresses group: 9.5% vs control group: 28.5%; OR 3.478, 95% CI 2.236-5.409, p<0.001, respectively]. Also, obstetric anal sphincter injury with and without episiotomy and second-degree tears with episiotomy were significantly lower in the perineal massage and warm compresses group [perineal massage and warm compresses group: 0.5% vs control group: 2.3%; OR 5.404, 95% CI 1.077-27.126, p = 0.040 and perineal massage and warm compresses group: 0.3% vs control group: 1.8%; OR 9.253, 95% CI 1.083-79.015, p = 0.042, respectively].
Conclusions:
The perineal massage and warm compresses technique increased the incidence of intact perineum and reduced the incidence of second-degree tear, episiotomy and obstetric anal sphincter injury.
Implications For Practice:
Perineal massage and warm compresses technique is feasible, inexpensive and reproductible. Therefore, this technique should be taught and trained to midwives students and midwives team. Thus, women should have this information and have the option to decide whether they want to receive the perineal massage and warm compresses technique in the second stage of labor.
