Study Notes
Labor Dysfunction
- Labor dysfunction can occur at any point in labor and can be classified as primary or secondary.
- Prolonged labor is associated with a higher risk of maternal postpartum infection, hemorrhage, and infant mortality.
Causes of Dysfunctional Labor
- Large fetus
- Hypotonic or hypertonic uterine contractions
- Uncoordinated contractions
- Ineffective uterine force
Uterine Contractions
- Uterine contractions are essential for moving the fetus in the birth canal
- Contractions occur due to the interplay of:
- Contractile enzyme (adenosine triphosphate)
- Major electrolytes (calcium, sodium, potassium)
- Specific contractile proteins (actin and myosin)
- Hormones (epinephrine, norepinephrine, oxytocin, estrogen, progesterone)
- Prostaglandins
Common Causes of Dysfunctional Labor
- Primigravida (first-time pregnancy)
- Cephalopelvic disproportion (e.g., in women with rickets) due to pelvic bone contraction, narrowing the pelvic diameter
- Abnormal fetal position:
- Posterior position instead of anterior position
- Extension of the fetal head instead of flexion
