Study Notes

5 P's of Labor

The 5 P's refer to Passage, Passenger, Powers, Psyche, and Partners, essential factors for understanding labor dynamics.

Passage

Two main types of pelvis: Gynecoid/Anthropoid (considered optimal) vs. Android/Platypelloid (considered unfavorable).

Passenger

Components include:
- Size: Refers to the dimensions of the fetus.
- Presentation: The part of the fetus entering the pelvis first, with vertex being the ideal position.
- Position: Describes the location of the back of the fetal head relative to the mother's pelvis.

Powers

Comprised of:
- Uterine contractions: Essential for labor progression, involving cyclic contraction and relaxation.
- Maternal pushing efforts: Voluntary actions by the woman during the second stage of labor.

Frequency: Time interval from the start of one contraction to the start of the next.
Duration: Length of each contraction, measured from start to finish.
Intensity: Muscle tone of the uterus at the peak of contraction, classified as mild, moderate, or strong.
Resting Tone: The muscle tone of the uterus when at rest between contractions.

Psyche

Maternal emotional state can significantly impact labor, encompassing emotional support and the woman's preparation for childbirth.

Partners

The relationship between the passenger (fetus) and the passage (pelvis) involves:
- Vertex presentation: Adjustments of sutures during navigation through the pelvis.
- Pelvic anatomy: Distinction between the "False Pelvis" and "True Pelvis," including the pelvic inlet, mid-pelvis, pelvic outlet, and pelvic floor.
- Station measurements:
  - "Zero station": Fetal head at ischial spines.
  - "Plus station": Fetal head below ischial spines.
  - "Minus station": Fetal head above ischial spines.

Signs of Impending Labor

Lightening: Downward movement of the fetus into the pelvic cavity, indicating engagement.
Braxton-Hicks Contractions: Irregular contractions that start after the third month of pregnancy.
Bloody Show: Pink-tinged mucus due to cervical dilation.
Spontaneous Rupture of Membranes: Leakage of amniotic fluid from the vagina, signaling the onset of labor.
