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.
