Normal Labor, Delivery, And Postpartum Care Flashcards
Normal Labor definition
Progressive cervical effacement and dilation resulting from regular uterine contractions that occur at least every 5 minutes and last 30 to 60 seconds.
Base of the skull
Firm, noncompressible bones that protect vital structures of the brain stem.
Vault of the skull or cranium bones
Occipital, two parietal, two frontal, two temporal bones
Molding
Overlapping of the cranial vault bones
Sagittal suture
Between the parietal bones connecting fontanelles
Lambdoid suture
From posterior fontanelle laterally, separates occiput and parietal bones
Coronal suture
From the anterior fontanelle laterally, separates parietal bones and frontal bones
Frontal suture
Separates frontal bones, runs from the anterior fontanelle to the glabella
Palpate these to find fetal head position
Anterior and posterior fontanelles
Posterior fontanelle closes
6 to 8 weeks
Anterior fontanelle ossifies
About 18 months (allows brain growth)
Bregma
Another name for the anterior fontanelle
Normal size of bregma
2x3 cm
Nastiness
Root of the nose, just below the glabella
Sinciput
Brow - between anterior fontanelle and glabella
Stage I - Latent Phase
contracting w/ 0 to 6cm dilation
Stage I - Active Phase
6cm to 10cm
Stage II
10cm to complete delivery of baby
Stage III
baby delivery until end of placental delivery
Normal Latent Phase (nulli and multi)
20 hrs, 14 hrs
Active Phase Cervical Dilation Rate (nulli and multi)
1.2 cm/hr, 1.5 cm/hr
Stage II normal duration
nulliparous < 3 hrs, multiparous < 2 hrs
Physiological cause of cervical change
breaking disulfide bonds
Normal timing for stage 3
30 min
