Focuses on care during labor and delivery.
Five Key Factors:
Passage Way (birth canal)
Passenger (fetus & placenta)
Position (relation between passage and fetus)
Power (physiological forces of labor)
Psychological & Psychosocial considerations
True Bony Pelvis: Forms the bony canal for birth.
Three sections:
Inlet
Pelvic cavity
Outlet
Fetal Skull: Largest and least compressible part.
Fetal Attitude: Refers to the relationship of fetal parts to one another.
Fetal Lie: Orientation of the fetus in relation to the mother.
Fetal Presentation: Part of the fetus that presents at the cervix (e.g., cephalic, breech).
Fetal Position: Relationship of the fetus to the maternal pelvis.
Fetal Station: Degree of descent of the presenting part.
Fetal Engagement: When the presenting part reaches or passes through the pelvic inlet.
Fetal head: Molds during birth due to sutures and fontanelles that allow flexibility.
Fetal Attitude: Position of fetal parts relative to one another.
Fetal Lie: Longitudinal (vertical) or transverse (horizontal).
Cephalic (vertex): Normal presentation of the head.
Breech:
Frank: buttocks presenting.
Full/complete: feet or legs presentation.
Footling: feet presenting.
Shoulder Presentation: Less common.
Engagement: Largest diameter of presenting part at pelvic inlet.
Station: Position relative to ischial spines of maternal pelvis.
Fetal position: Relation of fetal part landmarks to maternal pelvis.
These refer to the movements of the baby as it progresses through the birth canal:
Engagement
Descent
Flexion
Internal Rotation
Extension (restitution)
External Rotation (shoulder rotation)
Expulsion
Primary Forces: Uterine contractions.
Secondary Forces: Maternal pushing.
Contraction Phases: Frequency, duration, intensity.
Bearing Down: Can lead to cervical edema if not fully dilated.
Parents' Readiness: Critical for smooth labor.
Expectant women prepare mentally, may fear pain.
Empowering the mother by giving control is important.
Support systems greatly influence the birth experience.
Onset of Labor: Occurs typically between 38-42 weeks gestation.
Causes are not fully understood; linked with hormonal changes and physical readiness.
Levator ani muscle and fascia: Supports the bladder and uterus; thins as fetal head descends.
Signs include:
Lightening
Braxton Hicks contractions
Cervical changes
Bloody show
Rupture of membranes (ROM)
Sudden burst of energy prior to labor.
True Labor: Regular contractions, progressive dilation, and effacement.
False Labor: Irregular contractions, no cervical change, discomfort mainly in abdomen.
History and Risk Factors: Screening for intrapartum factors, review prenatal records, build trust with maternal patients.
Assess physical and psychosocial history; monitor vital signs and contractions continuously.
Develop a personalized care plan for laboring women.
First Stage: Onset of labor to full dilation (10 cm).
Latent phase: Early part.
Active phase: More intense.
Transition phase: End with increased anxiety and pressure.
Second Stage: Complete dilation to birth of the newborn.
Third Stage: Birth to delivery of placenta.
Fourth Stage: 1-4 hours post-delivery.
Monitor mother and newborn; promote maternal recovery and bladder emptying.
Ensure breastfeeding and bonding post-delivery.
Precipitous Birth: Labor < 4 hours, require assistance.
Preterm Labor: Regular contractions between 20 and 36 weeks; major risk factors include low socioeconomic status and previous preterm labor.
Cervical Ripening: Use of medications like misoprostol and prostaglandins.
Indications: Medical necessity (e.g., diabetes, PROM).
Various indications including fetal distress or abnormal positions; higher risks compared to vaginal births.
Criteria for candidates to safely attempt a vaginal delivery after cesarean.
Monitoring systems in place to assess maternal and fetal health during labor.
Address comfort needs, support decision-making in birth choices, monitor for complications, etc.
Holistic care approaches that include physiological, psychological, and social factors are crucial for both maternal and fetal well-being during labor and delivery.
