Study Notes
Labor and Delivery Overview
- Average blood loss at birth ranges from 300-500 ml.
- Blood pressure can increase by 15 mm Hg due to pain response and contractions.
- Epidural anesthesia may lead to hypotension; monitor closely for hemorrhage and hypertensive signs.
- Position mother on her side if receiving epidural and administer intravenous fluids as needed.
Respiratory System
- Increased respiratory rate occurs to accommodate elevated cardiovascular needs.
- Total oxygen demands can double during the second stage of labor.
- Monitor for hyperventilation; if present, offer a paper bag for breathing assistance.
Temperature Regulation
- Maternal temperature may rise during labor.
- Diaphoresis helps cool the body through evaporation.
- Signs of infection should be monitored; cool washcloths can provide comfort.
Fluid Balance
- Insensible water loss increases due to perspiration and deeper respiration.
- Women should be encouraged to hydrate with fluids or ice chips.
Urinary System
- Fetal head pressure reduces bladder tone, hindering the ability to sense fullness.
- Advise mothers to void every two hours to prevent overfilling and maintain bladder tone.
Musculoskeletal System
- Relaxin hormone softens joint cartilage, allowing pelvic joints to open approximately 2 cm for fetal passage.
- Monitor maternal mobility and be cautious of fall risks.
Gastrointestinal System
- GI activity slows during labor, delaying digestion and stomach emptying.
- Some women may experience loose bowel movements as contractions intensify.
- Offer fluids and ice chips to prevent dehydration, but light meals may be permitted.
Stages of Labor and Delivery
- First stage starts with uterine contractions, often prior to arrival at the birthing center.
- Maternal reassurance is crucial; fatigue and pain indicate normal labor progression.
Assessment and Monitoring During First Stage
- Maternal vital signs should be continuously monitored.
- Fetal heart rate (FHR) normal range: 110-160 beats per minute; assessed before, during, and after contractions.
- Monitor uterine contractions through palpation.
- Evaluate cervical dilation and effacement.
- Determine fetal station, presentation, and position via Leopold’s maneuver.
- Assist with pelvic examinations.
Second Stage of Labor (Expulsion)
- Lasts from full dilation and cervical effacement to the birth of the infant.
- Contractions shift to an uncontrollable urge to push, accompanied by heavy perspiration.
- As fetal head descends, crowning occurs, expanding from the size of a dime to a half-dollar.
Transition Phase
- Contractions peak in intensity, occurring every 2-3 minutes and lasting 60-90 seconds, achieving maximum dilation (10 cm).
- If not ruptured, membranes usually break at full dilation.
- Nausea, vomiting, and intense discomfort are common in this phase; feelings of loss of control may arise.
Care Strategies During Labor
- Encourage natural labor initiation without artificial induction.
- Promote mobility rather than bed confinement during labor.
- Ensure continuous support throughout labor.
- Avoid routine intravenous fluid administration unless necessary.
- Support non-supine birthing positions for mothers.
- Facilitate mother-baby bonding and breastfeeding post-birth.
- Favor spontaneous membrane rupture over amniotomy for natural progression.
