What are the factors that cause perineal laceration? There are four reasonable preventive measures

After the occurrence of perineal laceration, it is important to clarify the cause and pay attention to methods during delivery, especially reasonable prevention techniques.

Causes of perineal laceration

1. Maternal physical factors

(1) Age of puerpera: Advanced maternal age over 35 years old who gave birth for the first time have low perineal elasticity, low pelvic activity, and perineal body can not expand freely during childbirth, resulting in laceration. On the contrary, postpartum women have young reproductive age, incomplete development of the external genitalia, fewer wrinkles, and are also likely to experience perineal laceration during fetal head childbirth.

(2) Maternal pelvic factors: The posterior triangular area of the pelvic outlet is an important level during childbirth. Maternal pelvic dysplasia, narrow outlet, narrow pubic arch, overload pressure, and difficulty in stretching can cause perineal laceration.

(3) The postpartum vagina is severe. If the parturient has gynaecological inflammation such as Vaginitis and Vulvitis, some member organizations are relatively weak, and it is easy to congest during delivery. When the fetus is delivered to the Vaginal orifice, it is easy to tear the perineum.

2. Other factors

(1) Delayed delivery: This situation often occurs in primiparous women who lack reproductive experience. Due to the frequent occurrence of nervous tension, dysfunction of the cerebral cortex, and physical weakness during childbirth, the fetus may compress the soft birth canal for too long, resulting in a series of phenomena such as edema, congestion, and necrosis of the birth canal. During delivery, the local tissue is not strong enough, leading to perineal laceration.

(2) Abnormal fetal position: if the pregnant woman has abnormal fetal position, and the cephalopelvic region does not deliver, it is easy to have Uterine contraction fatigue, decreased fetal presentation, laborious labor, prolonged or even stagnation of labor. At this point, if the fetus is exposed and compressed in the birth canal for a long time, edema and necrosis of the birth canal can occur. During delivery, fragile local tissues can cause vaginal laceration.

Perineal laceration hazards

1. Harmful to normal urination: this situation not only occurs in perineum laceration, maternal pelvis is too small, fetus is too large, labor process is slow and other factors, vagina is supported for a long time, vagina is prone to laceration, and postpartum Urinary incontinence.

2. Impact on Dyspareunia in the future: The torn wound during childbirth will cause postpartum Dyspareunia, because the stitched scar is harder than the soft pudenda, and it is easy to cause pain when involved in sexual intercourse. If the incision or tear of the perineum is not only flat, but there are no poorly healed scars after repair, there will be no problem..
