Study Notes

Abruptio Placenta (cont'd):
- Patient reports sudden, severe abdominal pain.
- Patient no longer feels fetal movement.
- Vaginal bleeding with dark red blood.

Breech Presentations

If delivery imminent with buttocks presenting:
- Position woman with buttocks at edge of bed/stretcher, legs flexed.
- Allow newborn's buttocks and trunk to deliver spontaneously.
- Support the body once legs are clear.
- Lower the newborn slightly.

Shoulder Dystocia

Difficulty delivering shoulders.
If shoulders cannot clear birth canal, the fetus cannot breathe.
A major concern is brachial nerve plexus damage.
McRoberts Maneuver:
- Hyperflex the woman's legs tightly to the abdomen.
- Apply pressure to the lower abdomen and gently pull on the fetus's head.

Nuchal Cord

Umbilical cord wraps around the newborn's neck during delivery.
Slip a finger under the cord to gently attempt to slip it over the shoulder and head.
If unsuccessful, cut the cord.

Prolapsed Umbilical Cord

Cord emerges before the fetus.
Blocks oxygenated blood supply from the placenta.
Leads to fetal asphyxia.
Management:
- Keep woman supine with hips elevated.
- Administer 100% supplemental oxygen.
- Have woman pant with each contraction.
- Gently push the presenting part back up the vagina until it no longer presses on the cord.

Postpartum Hemorrhage

Can be early (within 24 hours of delivery) or late (24 hours to 6 weeks after delivery).
Blood loss exceeds 500 mL during the first 24 hours after birth.

Pathophysiology and Assessment Considerations

Pregnant patients react differently to trauma.
Tachycardia may be harder to interpret.
Signs of hypovolemia can be hidden.
Pelvic fractures increase bleeding risk.
Respiratory rate less than 20 breaths/minute is inadequate.

Arrival of the Newborn

If delivery in ambulance:
- Use blankets.
- Confirm ABCs (Airway, Breathing, Circulation).
- Place newborn on mother's chest.
- Suction mouth, then nose.
- Keep newborn at the mother's level.

The Apgar Score

Used to assess newborn condition at birth (and every 5 minutes if score is below 7).
Score ranges from 0-2.

Postpartum Hemorrhage (Cont'd)

Continue uterine massage.
Encourage breastfeeding.
Notify receiving facility of status immediately.
Transport immediately and prepare for IV.
Do not pack dressings into the vagina.

Algorithm for Neonatal Resuscitation

If newborn's pulse rate is apneic or less than 100 beats/min, begin positive pressure ventilation (PPV).
Begin chest compressions if pulse rate is less than 60 beats/min.
If ventilation and chest compressions don't improve bradycardia, administer epinephrine intravenously.

Pathophysiology and Assessment Considerations (cont'd):

First Trimester: Uterus well protected, rarely damaged by trauma.
Second and Third Trimesters: Uterus extends into abdomen, more vulnerable to trauma.

Abruptio Placenta (cont'd):
- Physical exam may reveal shock, tender abdomen, rigid uterus, and absent fetal heart sounds.
Placenta Previa (cont'd):
- Painless vaginal bleeding with bright red blood.
- Uterus is soft and nontender.
Ectopic Pregnancy:
- Ovum implants outside the uterus.
- Common symptoms include: Severe abdominal pain, and hypovolemic shock.
Third-trimester bleeding:
- Greatest bleeding danger.
- Large blood volume
- Pregnancy related compensatory mechanisms often present
