Final answer:
It is true that applying gentle pressure across the perineum with a sterile gauze pad can reduce the risk of perineal tearing during labor. While such techniques are part of practices to minimize tearing, the outcome can also depend on various other factors during childbirth.
Step-by-step explanation:
The assertion that the risk of perineal tearing during labor can be reduced by applying gentle pressure across the perineum with a sterile gauze pad is generally true. This technique is one among several methods intended to support the perineum during childbirth and potentially minimize tearing. While the application of pressure alone cannot guarantee the prevention of tearing since many factors are at play during labor, it is a part of a set of practices aimed at reducing the likelihood of perineal trauma.
During labor, the perineum undergoes significant stretching as the baby moves through the birth canal. Historically, an episiotomy, which is a surgical incision in the perineum, was commonly performed to prevent tearing. More recently, the trend has moved towards allowing the perineum to tear naturally, if it occurs, because natural tears generally heal more quickly and are associated with fewer complications than an episiotomy. In both cases, whether it is a natural tear or a surgical cut, suturing is required after birth for proper healing.
