Introduction to First-time Mothers and Their Labor Process

A first-time mother refers to a woman who is experiencing her first childbirth. Due to individual differences, the duration of labor may vary. Overall, compared to women who have undergone childbirth before, the total duration of labor for first-time mothers is typically longer, but most often falls within a controllable range. If the labor process is prolonged or the conditions for a natural birth are unfavorable, doctors may recommend cesarean delivery.

To delve deeper into the specifics of the labor process for first-time mothers, let's break it down into three stages:

First Stage: This stage refers to the time from the official start of labor to the full dilation of the cervix. It involves the cervix dilating from closed to approximately 10 centimeters. This stage typically takes the longest and is crucial for a successful natural birth. It can be further divided into latent and active phases. The latent phase begins with the establishment of regular contractions and lasts until the cervix dilates to about 2-3 centimeters. During this phase, cervical dilation is slow, averaging about 2-3 hours, with each centimeter taking approximately 8 hours to dilate. The active phase begins when the cervix dilates to 2-3 centimeters and continues until full dilation. During this phase, cervical dilation occurs much faster, typically taking about 4 hours to complete.

Second Stage: This stage begins with full dilation of the cervix and ends with the delivery of the baby. For first-time mothers, this stage averages about 1 hour, and if it extends beyond 2 hours, it is considered prolonged. This period is also known as the fetal expulsion stage, which is crucial for both the mother and the baby's prognosis. The mother should cooperate well with the midwife and apply appropriate force without moving the hips excessively to prevent severe perineal tears and affect postpartum recovery. Prolongation of this stage can increase the risk of intracranial hemorrhage for the baby due to extended exposure to the pelvic cavity and repeated impact of the fetal head on the pelvic floor during contractions and abdominal pressure. Therefore, avoiding prolongation of the second stage is essential, and if necessary, obstetric forceps or fetal head suction may be used to assist in delivery.

Third Stage: This stage begins with the delivery of the baby and ends with the expulsion of the placenta. It typically takes 5-10 minutes and should not exceed 30 minutes. If the placenta has not been expelled after 30 minutes or if there is placental adhesion, manual removal of the placenta may be necessary, and in severe cases, cesarean surgery may be required. Prolongation of the third stage can lead to postpartum hemorrhage, so it is crucial to monitor uterine contractions and observe postpartum blood loss closely.

In summary, the normal labor process consists of the sum of these three stages, from the official start of labor to the expulsion of the placenta, which should take less than 24 hours, typically ranging from 8 to 12 hours. Labor lasting over 24 hours is considered delayed.
