Study Notes
Labor and Delivery
- During labor, uterine contractions occur at intervals of 2-4 minutes and are described in terms of the frequency within a 10-minute period.
- The frequency of contractions in advanced labor is 3-4 contractions per 10 minutes.
- The average duration of a first labor is 12-24 hours.
- Cervical softening or 'ripening' during pregnancy is caused by prostaglandins and estrogen.
Cervix During Labor
- During labor, the cervix undergoes significant changes, including softening, effacement, and dilatation.
- The cervix is fully dilated at 10 cm.
Maternal Urge to Push
- The maternal urge to push during labor is caused by pressure on the rectum and pelvic floor.
Post-Natal Cervix
- After delivery, the cervix returns to its normal size, but remains slightly larger than its pre-pregnancy size.
- The characteristic shape of the parous cervix after delivery is more flare-shaped.
- The purpose of assessing the postnatal cervix is to check for any abnormalities or trauma.
Lochia
- Lochia is the vaginal discharge that occurs after delivery.
- During the first few days after delivery, lochia is red and consists of blood and decidua.
- During the second week after delivery, lochia becomes serous and yellowish.
- Persistent red lochia suggests abnormal bleeding.
Uterine Relaxation and Contraction
- Progesterone maintains uterine relaxation by suppressing prostaglandin production and preventing oxytocin release.
- Oxytocin and prostaglandins stimulate uterine contractions during labor.
- The role of prostaglandins and oxytocin in the uterus during labor is to stimulate contractions.
Labor Stages
- The second stage of labor, also known as the active second stage, is characterized by active pushing and is typically shorter in multiparous women.
- The passive second stage of labor, also known as the latent phase, typically lasts up to 2 hours.
- Prolonged labor is defined as a labor lasting more than 24 hours in nulliparous women.
- Precipitous labor is defined as a labor lasting less than 3 hours.
Cardiotocography (CTG)
- The purpose of a cardiotocograph (CTG) during labor is to monitor fetal heart rate and detect any abnormalities.
Uterine Changes During Labor
- The process called "effacement" occurs when the uterine smooth muscle cells progressively shorten and the lower segment of the uterus becomes thinner and more stretched.
- Effacement increases the diameter of the birth canal, allowing the fetus to pass through.
Puerperium Period
- The duration of the puerperium period is 6-8 weeks after delivery.
