Normal Labour

Q: What is the defining characteristic of normal labour in terms of fetal presentation?

Normal labour is characterized by a singleton fetus in cephalic presentation. This reduces the risk of complications during delivery.

Q: What is the expected duration of the active phase of the second stage of labour in a nulliparous woman without epidural anesthesia?

The active phase of the second stage of labour in a nulliparous woman without epidural anesthesia is expected to last ≤2 hours. This duration helps in assessing labour progress.

Q: What is the primary mechanism of labour in the third stage?

The primary mechanism of labour in the third stage is placental separation, also known as placental expulsion. This stage involves the delivery of the placenta.

Q: A woman in labour is at risk of postpartum hemorrhage (PPH). What is the most effective way to reduce this risk?

Administering oxytocin 10 IU IM within 1 minute of delivery is the most effective way to reduce the risk of PPH. Oxytocin helps in uterine contraction and reduces bleeding.

Q: What is the significance of the partograph in labour management?

The partograph is used to assess cervical dilation and fetal station. It helps in monitoring the progress of labour.

Normal labour is a spontaneous process that starts with low-risk conditions and progresses without undue prolongation, ultimately leading to a vaginal delivery with minimal maternal and neonatal morbidity. Understanding normal labour is crucial for medical students as it provides a foundation for recognizing deviations from the norm and managing complications effectively. Mastering the physiology and stages of normal labour enables medical professionals to provide optimal care and support to mothers during childbirth, making it an essential aspect of obstetric education.
