Contractions 4-20 minutes, 15-40 seconds2. Active (4-8 cm); lasts 4-6 hoursContractions more intense3. Transition (8-10 cm); “hurricane hour”Shakes, N&V, flashes/chills, fears being left aloneContractions 1-3 minutes, 90 seconds long.B. Second Stage = dilation to delivery-Contractions 60-90 seconds, every 1-3 minutes-pushing, more control, fear tearingC. Third Stage = delivery of placenta within 30 minutesD. Fourth Stage = 1-4 hours after birth-Uterine involution- oxytocin, methergine-shakes/shivers-hungry, talkative, exhausted-250-500 mLs lost at birthOB Notes48

Specific Risk FactorsA. Hypertonic Labor1. Increased frequency but decreased intensity of contractions2. occurs after labor has been initiated3. Associated with primapara mothers, in relation to anxiety and pain (hypoxia to uterus d/t tensing)4. risks: increased fatigue and discomfort, maternal dehydration, decreased coping, fetal distress5. Tx: rest and relaxation (breathing techniques, sedatives), fluids, comfort measures.B. Hypotonic Labor1. Regular contractions slow to <2-3 contractions in 10 minute period2. occurs after labor has been initiated3. Causesoverstretching of the uterus omultiplesohydramniosobowel and bladder distentionempty bladder to help contractions resume smoother contraction If water broke early onRisk of infection 4. risks: increase fatigue and length of labor, fetal distress, infection5.
