    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.
