Stages and phases of labor 👶🏻. First stage includes 3 phases:
1) Latent phase- lasts through the first 3 cm of dilation. Cervical effacement and fetal position change occur during this phase. Duration varies, but this phase can last more than 8 hours. Contractions gradually increase, intervals shorten until they are 5 min apart, and duration increases to 30-40 seconds by the end of latent phase. •Back discomfort with each contraction~ similar to menstrual cramps. •Mom is usually sociable, excited, and cooperative.
2) Active phase- Cervix dilated from 4-7 cm and at a more rapid rate than latent. Effacement of cervix is completed. Fetus descends into the pelvis, and internal rotation begins. Contractions are about 2-5 min apart, with duration of about 40-60 seconds. Intensity is moderate to strong. •Mom becomes more anxious. Unlikely to initiate interactions. Becomes more concentrated.
3) Transition phase- Cervix dilated from 8-10 cm and fetus descends further down into the pelvis. This stage is short, but intense. Can last 3-4 hours. Contractions are strong and can be as frequent as 1.5 to 2 min apart, and the duration is 60-90 seconds 😰. Mom may feel the urge to push and bear down. • Leg tremors, nausea, and vomiting are common. • If Mom didn’t choose and epidural, this stage can be the most difficult. Mom may be irritable and lose control.
