Study Notes
Uterine Contractions
- Hypotonic Contractions: Characterized by poor and inadequate uterine contractions leading to prolonged delivery; insufficient for cervical dilatation and fetal descent.
- Hypertonic Contractions: Involves frequent contractions with high resting tone, resulting in excessively painful experiences without productive labor.
- Inertia and Dysfunctional Labor: Inertia refers to sluggishness of contractions; the modern term for this condition is dysfunctional labor.
Labor Types and Components
- Precipitate Labor: Defined as rapid and short labor, often with few contractions leading to quick delivery.
- Dystocia: Describes difficult labor, influenced by four key components known as the 4 P's: Power, Passenger, Passageway, and Psyche.
Labor Components
- Power: Refers to the uterine contractions that propel the fetus during labor.
- Passenger: Represents the fetus itself in the labor process.
- Passageway: The birth canal through which the fetus must pass.
- Psyche: Reflects the perception of the labor experience by the woman and her family.
Prolonged Labor
- Risks associated with prolonged labor include maternal postpartal infection, hemorrhage, and increased infant mortality.
- Common causes of dysfunctional labor can include pelvic abnormalities, poor fetal positioning, and maternal exhaustion.
Oxytocin
- Oxytocin is administered to stimulate uterine contractions during labor and aid in lactation post childbirth.
- It markedly increases the strength and frequency of uterine contractions.
Hypotonic Contractions Details
- Contractions occur infrequently (2-3 in a 10-minute period) and have low resting tone (less than 10 mmHg).
- Strength of contractions does not exceed 25 mmHg and can lead to complications such as maternal exhaustion and postpartum hemorrhage.
Hypertonic Contractions Details
- In contrast, hypertonic contractions exhibit high resting tone (>15 mmHg) and are frequent but not productive.
- Occurs primarily in the latent phase of labor and may cause increased pain due to muscle tenderness and lack of relaxation.
Precipitate Labor Consequences
- Precipitate labor can result in subdural hemorrhage for the fetus due to rapid pressure release.
- Women may experience lacerations in the birth canal from forceful births, risking severe complications.
Causes and Symptoms of Precipitate Labor
- Factors leading to precipitate labor include strong uterine contractions, a smooth birth canal, and previous rapid labors.
- Signs include sudden onset of contractions, intense pain, prolonged feelings of contractions, and an urgent need to bear down.
Risks Associated with Precipitate Labor
- For mothers, risks include severe tearing, uterine bleeding, shock, and potential infections.
- For babies, risks consist of infections and aspiration of meconium and amniotic fluid.
