Study Notes
Cephalopelvic Disproportion
- Primary issue: Fetal head or body is too large to fit through the maternal pelvis
- Associated maternal condition: Maternal pelvic deformities or small pelvis
Fetal Macrosomia
- Associated maternal condition: Diabetes and excessive fetal size are not the only causes
- Not always caused by excessive fetal size
Pelvic Deformities
- Can be caused by: Rickets, osteomalacia, or a congenital anomaly
Dystocia
- Can be caused by: Fetal anomalies, such as hydrocephalus
- Most common fetal malposition: Occiput posterior position
- Percentage of labors with breech presentation: 3-4%
- Characteristic of frank breech presentation: Fetus's legs are folded in front of their body
Multiple Gestations
- Type of gestation involving twins, triplets, quadruplets, or more infants: Multifetal gestation
- Percentage of live births in the United States in 2017 involving multiples: 3.4%
Fetal Malposition
- Characterized by one or both hips being partially or fully extended: Footling breech presentation
Precipitous Labor
- Defining characteristic: Labor lasting less than 3 hours
- Associated with: Hypertonic uterine contractions
- Can result from: Pelvic contractures reducing the capacity of the bony pelvis
- Not associated with: Hypotension
Multifetal Pregnancies
- Usual method for managing malpresentation: External Cephalic Version (ECV)
- Predisposing factor in adolescent mothers: Pelvic dystocia
- Nurse's role in twin gestations: Assisting with the birth of the second fetus
- Potential fetal complication: Birth asphyxia
Operative Vaginal Births
- Risk associated with: Instrumental delivery
Internal Version
- Potential risk in multifetal pregnancies: Fetal injury or death
External Cephalic Version (ECV)
- Purpose: To turn the fetus into a vertex position
- Usual gestational age: 36-37 weeks
- Success rate at 36-37 weeks of gestation: 50-70%
Multiple Gestation Pregnancies
- Rise in the 1980s and 1990s due to: Increased use of assisted reproductive technology
- Internal Version: A procedure that involves manually turning the fetus into a vertex position
- Women aged 35 years and older are naturally more likely to have a multiple gestation pregnancy due to: Hormonal changes that increase the release of multiple eggs during ovulation
