what is the definition of normal labour?

INTRODUCTION. In 1997, the World Health Organization defined normal birth as "spontaneous in onset, low-risk at the start of labor and remaining so throughout labor and delivery. The infant is born spontaneously in the vertex position between 37 and 42 completed weeks of pregnancy.

Early Labor Phase –The time of the onset of labor until the cervix is dilated to 3 cm. Active Labor Phase – Continues from 3 cm. until the cervix is dilated to 7 cm.

In active labor, the contractions are less than 5 minutes apart, lasting 45-60 seconds and the cervix is dilated three centimeters or more. In the event you are in early labor and sent home, it is common to feel disappointed, maybe even embarrassed.

Cervical effacement and dilation. During the first stage of labor, the cervix opens (dilates) and thins out (effaces) to allow the baby to move into the birth canal. In figures A and B, the cervix is tightly closed. In figure C, the cervix is 60 percent effaced and 1 to 2 cm dilated.

But for some, a shorter labour can mean a more intense labour with stronger contractions; while dilation during the first pregnancy happens at roughly 1.2cm per hour, it's more like 1.5cm per hour for second and subsequent births which can make things quicker, but possibly more painful.

The first stage of labor is the longest and involves three phases: Early Labor Phase –The time of the onset of labor until the cervix is dilated to 3 cm. Active Labor Phase – Continues from 3 cm. until the cervix is dilated to 7 cm.

On average the intervals last ten minutes to an hour. So-called interrupted labor is sufficiently common in the cat to be considered a normal occurrence.

Some of these can be very subtle, and you may not even notice them. Contractions are the most common first sign of labor. Just before you go into labor, your cervix, the lower part of your uterus, will soften, thin out, and shorten. You may feel a little discomfort, maybe even a few light, irregular contractions.

Differences between an induced and a natural labour In natural labour, the contractions build up slowly, but in induced labour they can start more quickly and be stronger. Because the labour can be more painful, you're more likely to want some type of pain relief.

Active labor (the time you should come into the hospital) is usually characterized by strong contractions that last 45 to 60 seconds and occur three to four minutes apart. SOURCE: American Pregnancy Association.

In general, though, once active labor begins, the average progress is about 1 centimeter dilation per hour for your first baby and 1 1/2 centimeters per hour for a second baby.

One of the first signs of impending labour is a drop in mum's body temperature from 38.5°C to 37°C – labour usually begins around 12-24 hours after that.

Your cervix needs to open about 10cm for your baby to pass through it. This is what's called being fully dilated. In a 1st labour, the time from the start of established labour to being fully dilated is usually 8 to 12 hours. It's often quicker (around 5 hours), in a 2nd or 3rd pregnancy.

Labor induction — also known as inducing labor — is the stimulation of uterine contractions during pregnancy before labor begins on its own to achieve a vaginal birth. A health care provider might recommend labor induction for various reasons, primarily when there's concern for a mother's health or a baby's health.

You're Having Strong, Regular Contractions When true labor begins, the contractions start as mild, irregular cramps that become regular and more painful over time. You usually can't feel your baby move during the cramp or contraction.

Childbirth, also known as labour and delivery, is the ending of pregnancy where one or more babies leaves the uterus by passing through the vagina or by Caesarean section.

When true labor begins, the contractions start as mild, irregular cramps that become regular and more painful over time. You usually can't feel your baby move during the cramp or contraction. The contractions push the baby's head down, slowly thinning and opening the cervix; this is called effacement and dilation.
