The first stage of labor is the longest stage. 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).
Prolonged labor is labor that has slow progression — whether in the first or second stage. If your baby isn't born after 20 or more hours of contractions, you're most likely in prolonged labor. Also called failure to progress, providers can safely manage this condition with medications to help speed labor along.
Transition phase of labor
The end of active labor is sometimes referred to as the transition to the second stage of labor. It's when the cervix completely dilates to a full 10 centimeters, and is the shortest – but generally considered the hardest – part of labor.
The first stage of labor, also called early labor, is by far the longest. It begins at the onset of labor and continues until the cervix is fully dilated.
The third stage is usually the longest stage, lasting about 4 hours.
The last and the longest stage of prenatal development is called the fetal stage, and it lasts from the ninth week until birth.
First stage of labor
According to Friedman et al, latent stage considered to be prolonged if takes >20 hours for nulliparous women and >14 hours for multiparous women. However, prolonged latent phase does not usually lead to any clinically significant adverse events for mother or the infant.
Past researches have revealed that the average duration of the third stage of labor is between 6–7 minutes. [5,6] Factors that can influence this time interval need to be studied.
The third stage of labor (TSL) is defined as the time between the delivery of the baby and the expulsion of the placenta. The duration of the third stage is ~6-30 minute(3,4).
The first stage starts when labor begins and ends with full cervical dilation and effacement. The second stage commences with complete cervical dilation and ends with the delivery of the fetus. The third stage initiates after the fetus is delivered and ends when the placenta is delivered.
For most people, active labor is more painful than pushing because it lasts longer, gets more and more intense as it progresses, and involves many muscles, ligaments, organs, nerves, and skin surfaces.
The first stage of labor happens in two phases: early labor and active labor. Typically, it is the longest stage of the process. During early labor: The opening of the uterus, called the cervix, starts to thin and open wider, or dilate.
Early labour is the first, and usually the easiest and longest phase. Your cervix begins to dilate and thin in this phase.
But a lot is still happening. During the third stage of labor, you will deliver the placenta. How long it lasts: The placenta is typically delivered in 30 minutes, but the process can last as long as an hour.
The second stage of labor begins once you are fully dilated to 10 cm. Your provider will let you know that it is time to start pushing your baby out. This stage can be as short as 20 minutes or as long as a few hours.
"As soon as someone is admitted to the hospital, they're kind of on the clock," Caughey said. -If women aren't too tired, allow them to push at least two hours if they have delivered before, three hours if it's their first baby. They may push longer if they had an epidural as long as the doctor can see progress.
When the third stage of labor is prolonged beyond 20-24 minutes (as opposed to the 30 minutes that was the earlier benchmark), it may be a risk factor for postpartum hemorrhage (PPH) which kills more than 1.25 million women a year.
Third stage
If the delivery is prolonged more than 30 minutes, the obstetrician is forbidden to manually pull the umbilical cord because it may cause uterine inversion and massive hemorrhaging (over 500 mL). A physiological hemorrhage up to 500 mL is expected during the delivery of the placenta.
Labor with a subsequent children is known to go faster, especially if you have them two or three years after your last. Your body is a little more laxed.
How long does the second stage of labour last? Usually, your baby will be born within three hours of active pushing if it's your first baby, and within two hours for second and subsequent births (NICE, 2017; Hofmeyr and Singata-Madliki, 2020). But it can be much quicker.
Introduction. Prolonged second stage of labour is usually defined as 2–3 hours for primiparous women and 1–2 hours for parous women, with the longer interval for women with epidural analgesia during labour.
Three stages
The dilation (opening) stage is the longest, while the expulsion (pushing out) stage lasts 30-60 minutes, and the placental stage takes from a few minutes to up to 60 minutes.
Late adulthood spans the time when we reach our mid-sixties until death. This is the longest developmental stage across the lifespan.
The first trimester is the most crucial to your baby's development. During this period, your baby's body structure and organ systems develop. Most miscarriages and birth defects occur during this period. Your body also undergoes major changes during the first trimester.
