First Stage of Labour: What To Expect During Childbirth?

The first stage of labour begins at the start of labour and ends when your cervix is fully open. This is the longest stage of delivery, during which many processes occur in your body before you reach the pushing stage. Below is a description of the processes that occur in your body, monitored by your doctor, and methods of pain relief.

In the first stage of labour, many things occur, such as the opening of the cervix to allow the baby through. Knowing what goes on can make the process a bit less mysterious.

What Is the First Stage of Labour?

Labour process stage one begins after entering into established labour, where there is dilation of the cervix by means of contractions. Labour stage one ends once there is total cervical dilation. The first stage of labour is usually subdivided into the latent and established stages, when dilation is slow and rapid respectively. This stage is the longest of all three stages of labour and may last for many hours, particularly for first-time mothers.

What Do Dilation and Effacement Mean?

Two main changes take place during this period. Understanding them can help you make sense of updates from your doctor.

  • Firstly, dilation means the degree of your cervical opening and is measured in centimetres, ranging from 0 (no dilation) to 10 (completely dilated). Dilation is the first sign used by doctors to measure the progress of labour.
  • Secondly, effacement shows how much your cervix thins out. Before labour, the cervix is thick, similar to a closed door; however, during labour, it gradually becomes thinner, and this change is described in percentages from 0 to 100 per cent effacement.
  • Thirdly, station describes how low in your pelvis your baby moved, and how close he or she is to birth, measured relative to a fixed point on your pelvic bones.
These three parameters provide the doctor with additional information concerning the course of your labour, other than just how intense your contractions are.

How Do Doctors Keep Track Of Your Progress?

As a matter of fact, your doctor monitors you and your baby during the entire course of this stage once you go into labour. Typically, this involves the following:

  • Vaginal exams: The cervix will be examined for dilation and effacement, usually done every few hours. This allows your doctor to understand how your labour proceeds and if something requires more attention.
  • Monitoring of the heart rate of your baby: The heart rate of your baby is monitored periodically or continuously depending on the situation.
  • Monitoring of your contractions: The contractions of your baby are monitored. This includes the measurement of their frequency and strength.
  • Measurement of your vital signs: Your blood pressure, heart rate and body temperature are monitored periodically.

What Are Your Pain Relief Options?

No one method to relieve pain is better than others, and the possible pain relief choices are as follows:

  • Relaxation and breathing exercises: You can use drug-free and simple methods at the beginning of the first stage.
  • Gas and air: The most common type of inhaler pain reliever administered under your own control.
  • Injected pain relief: There are specific medications that can be injected in order to make contractions less painful temporarily.
  • Epidural pain relief: A more advanced way to relieve pain via injection in the lower part of your back, providing numbness in the lower body parts.
Your doctor will explain everything about the possible pain relief methods that will suit you best, and you have the right to reconsider your decision anytime during delivery.

When Should You Contact Your Doctor?

It is important to maintain contact with your doctor during this stage, and you should consider contacting them if you experience any of the following:

  • If you doubt that your labour has indeed been established
  • If you feel your pain cannot be managed with your present pain relief method
  • If you have any questions regarding your progression or your baby’s heartbeat
  • If you feel uneasy and need reassurance of any sort
It is the role of the doctor to provide clarification on what each measurement means to you; hence, do not hesitate to ask.

The first stage asks your body to do quiet, steady work long before you reach the moment of pushing. Trust the process and ask your questions freely; remember, each centimetre brings you closer to your baby.
