Flashcards in Chapman Ch 8 Intrapartum Deck (8)
Cardinal movements of labor
Positional changes that the fetus goes through to best navigate the birth process
When the greatest diameter of the fetal head passes through the pelvic inlet late in pregnancy or early in labor
Movement of the fetus to the birth canal during the first and second stage of labor
When the chin of the fetus moves toward the fetal chest. Occurs when the descending head meets resistance from maternal tissues. Results and smallest fetal diameter to the maternal pelvic dimensions. Normally during early labor
When the rotation of the fetal head aligns the long axis of the fetal head with the long axis of the maternal Pelvis. Mainly during second stage of labor.
Facilitated by resistance of the pubic floor that causes the presenting part pivot beneath the pubic symphysis and the head to be delivered. Occurs during the second stage of labor
Sagittal suture moves to a transverse diameter and the shoulders aligned in the Anteroposterior diameter. Sagittal suture maintains alignment with the fetal trunk as the trunk navigates through the pelvis.
