Study Notes
Normal Labor
- Normal labor is a process by which the uterus contracts to push the fetus out of the birth canal.
- It typically starts when the cervix is fully effaced and dilated to 10 cm.
Stages of Labor
-
Stage 1: Early Labor
- Begins when the cervix starts to dilate and efface
- Lasts for several hours or days
- Contractions are mild and irregular
-
Stage 2: Active Labor
- Cervix dilates from 4-7 cm to 10 cm
- Contractions are stronger and more frequent
- Lasts around 4-8 hours for first-time mothers and 2-4 hours for subsequent pregnancies
-
Stage 3: Transition
- Cervix is fully dilated to 10 cm
- Contractions are very strong and frequent
- Lasts around 30 minutes to 1 hour
-
Stage 4: Pushing
- Fetus is pushed out of the birth canal
- Lasts around 1-2 hours for first-time mothers and 30 minutes to 1 hour for subsequent pregnancies
Signs and Symptoms of Labor
-
Early Labor
- Mild contractions
- Pelvic pressure
- Backache
- Bloody show
- Nausea and vomiting
-
Active Labor
- Stronger contractions
- Increased pelvic pressure
- Increased backache
-
Transition
- Very strong contractions
- Feeling of rectal pressure
- Feeling of needing to have a bowel movement
-
Pushing
- Feeling of relief after delivery
Mechanism of Labor
- Uterine contractions push the fetus down the birth canal
- Cervix effaces and dilates to allow the fetus to pass through
- Contractions become stronger and more frequent as labor progresses
- Fetus is pushed out of the birth canal during the pushing stage
