If your baby is not born after approximately 20 hours of regular contractions, you are likely to be in prolonged laborProlonged labor can be determined by labor stage and whether the cervix has thinned and opened appropriately during labor. If your baby is not born after approximately 20 hours of regular contractions, you are likely to be in prolonged labor. Some health experts may say it occurs after 18 to 24 hours.https://www.webmd.com › prolonged-labor-causes-treatments
Prolonged labor, also known as failure to progress, occurs when labor lasts for approximately 20 hours or more if you are a first-time mother, and 14 hours or more if you have previously given birth. A prolonged latent phase happens during the first stage of labor.
The four stages of labour
“How long it will last is extremely variable,” says Arntfield. You could spend up to 48 hours in this phase, which can be intense and draining but isn't generally cause for concern.
For first-time moms, it can last from 12 to 19 hours. It may be shorter (about 14 hours) for moms who've already had children. It's when contractions become strong and regular enough to cause your cervix to dilate (open) and thin out (efface).
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.
First-time moms are usually in labor for about 12 to 18 hours, on average. If you've had a baby before, labor usually goes more quickly, usually about half that amount of time.
Prolonged labor can result from a variety of different issues, such as fetal malpresentation, issues with uterine contractions, cervical dystocia or stenosis, and cephalopelvic disproportion. Both fetal malpresentation and cervical dystocia may result in obstructed labor.
There's no clear-cut deadline, and every woman is different, stressed Caughey, obstetrics chairman at the Oregon Health and Sciences University. "My patients ask this every day," he said. He tells them it can "run the gamut from six hours long, start to finish, to three and four days" at the other extreme.
Labor that progresses too slowly may involve slow movement of the fetus through the birth canal because the fetus is too large or is abnormally positioned, the birth canal is too small, or the uterus contracts too weakly or too strongly.
This is perfectly normal. The duration of the latent phase of labour can be variable. It may last for 24 hours or more and can be exhausting for you. It helps if you can stay as relaxed as possible during this part of your labour and remain at home in comfortable surroundings as long as you can.
The first stage of labor is the longest. This is when your cervix will open to 10 centimeters dilated. This stage of labor can take anywhere from six to 36 hours. Keep in mind that this stage of labor can take longer for first-time moms.
It's common to think the first signs of contractions are your cue to come to the hospital, but that's usually not the case. Early labor can last for days.
Getting up and moving around may help speed dilation by increasing blood flow. Walking around the room, doing simple movements in bed or chair, or even changing positions may encourage dilation. This is because the weight of the baby applies pressure to the cervix.
Active labour typically lasts between 4 and 8 hours — or longer. The last part of active labour is referred to as transition. Contractions will come close together and may last for as long as 60 to 90 seconds. At this point, the mother may feel the urge to push and will feel pressure in her lower back and rectum.
Sometimes women start to have contractions and then they fade away. These can be deceptive, and make you think you are in labour. You go to hospital, only to find everything stops. If this happens to you, you may be examined and disappointed that you aren't very far on in your labour.
Nonprogressing contractions.
Contractions that are not getting longer, stronger and closer together. This may mean that the contractions are not opening the cervix. It usually means that other work is being done, such as turning your baby to a different position, softening or thinning the cervix.
If labour stalls for a medical reason, an IV of synthetic Oxytocin is often the best route forwards. Sometimes this will help labour to progress until its conclusion, and sometimes this will lead down the pathway to a necessary Caesarean birth.
It's not always possible to choose the date for your c-section. When you do have the option, talk with your doctor about the best time for delivery, and share your own personal wishes. Most of the time, a c-section should not be scheduled until you have reached 39 weeks.
However, allowing a labor to continue for too long carries health risks for both the mother and child, including oxygen deprivation, permanent injury, and trauma in the child, and hemorrhaging and infection in the mother.
Maternal risk factors that increase the risk for prolonged labour include primiparity [11] and total maternal weight gain or high body mass index [12,13]. Foetal risk factors include a heavy birth weight, large head circumference and occiput posterior presentation [14,15].
The corrected perinatal mortality was 165 per 1000 total births, which was also directly related to the duration of labour, and 74.3% of the perinatal deaths occurred in the patients with obstructed labour. The perinatal mortality in the study group was nearly three times higher than the overall hospital group.
Prolonged labor can be determined by labor stage and whether the cervix has thinned and opened appropriately during labor. If your baby is not born after approximately 20 hours of regular contractions, you are likely to be in prolonged labor. Some health experts may say it occurs after 18 to 24 hours.
