How long does the delivery stage typically last?
The delivery stage usually lasts between 30 minutes to an hour, though this can vary. The mother pushes during contractions to deliver the baby through the birth canal.
195
What happens during the third stage of labor?
After the baby is born, the placenta and umbilical cord are expelled from the uterus. It is essential for the entire placenta to be expelled to prevent health complications for the mother.
196
What is an episiotomy?
An episiotomy is an incision made in the vaginal opening to widen it, helping prevent tearing during delivery. It is typically used when necessary to aid the birth process.
197
What does "failure to progress" in labor mean?
"Failure to progress" refers to labor not progressing as expected, either taking too long or not progressing despite the mother’s efforts. It may require medical intervention, such as medications to help the process.
198
What is a breech presentation, and why is it risky?
