Study Overview
Brief Summary
The aim of this study is to evaluate the effect of a combined perineal massage and warm compresses intervention on the perineum integrity during second stage of labor.
Detailed Description
A single-centre, prospective, randomized controlled trial was conducted. Eligibility and informed consent to participate were checked once the woman was in established labor. Eligible participants were randomized at the second stage of labor. The trial intervention took place during the second stage of the spontaneous vaginal birth. Participants were randomized to one of the two groups, perineal massage and warm compresses on second stage of labor or control group (hands-on).

Masking Description
The randomization envelope was opened by the midwife when the participant entered the second stage of labor and was destroyed thereafter. The allocation was only shown to the midwife and if necessary, the obstetrician. The trial intervention took place during the second stage of the spontaneous vaginal birth. Participants were randomized to one of the two groups, perineal massage and warm compresses on second stage of labor or control group (hands-on). The participants were blinded to their allocation. After the placenta delivery, a blinded midwife not otherwise involved in the birth but trained, assessed the perineum (graded the perineal tears). The data about the variables included in the study were registered by the midwife responsible for the birth. Midwives who assess the primary outcomes and the principal investigator were blinded to the randomization.

Arms & Interventions
PeMWaC (Perineal Massage and Warm Compresses)
In the second stage of labor, the midwife performed a soft perineal massage between 3 o'clock and 9 o'clock positions (U-shaped reciprocating motion) wearing sterile gloves and lubricated their hand with sterile lubricant. The massage lasted 10 minutes and the degree of downward pressure by the thumb was determined according to mothers' response. Perineal massage was established on the II Hodge Plan, between maternal contractions and regardless of maternal position. The women could adopted the birthing position they prefer. The application of warm compresses was performed by the midwife between the III and IV Hodge plans, during pushing and regardless of the mother's position. A metal jug filled with warm water (between 45° and 59°C) was used to soak the compresses, which were squeezed out before being gently placed on the perineum during contractions.
Intervention: Perineal Massage and Warm Compresses (PeMWaC) (Procedure)
Control group (Hands-on)
The midwife placed the index, middle, and little fingers of the non-dominant hand together on the child's occiput, with the palm facing the anterior region of the perineum, when the child's head was crowning. In this way, the expulsion was controlled, maintaining the flexion of the head. Simultaneously, the dominant hand was flattened and placed on the posterior region of the perineum, with the index finger and thumb, forming a "U", exerting pressure on the posterior region of the perineum during the crowning process. During the birth of the shoulders and the rest of the body, the dominant hand was kept in place, protecting the posterior region of the perineum, while the non-dominant hand supported the infant's head, allowing external rotation and spontaneous birth of the shoulders. After both shoulders were removed, the midwife removed the dominant hand from the posterior perineum.
Intervention: Control Group (Hands-on) (Procedure)
