Birth-Related Complications

Core Concepts

Soft-tissue injuries of the scalp: three patterns, three meanings

The scalp bears the brunt of birth trauma, and the three classic injuries are distinguished by anatomy:

• Caput succedaneum — soft swelling of the scalp above the periosteum (the tissue over the bone), from pressure against the cervix or vacuum. It crosses suture lines, is present at birth, and resolves within days. Benign.
• Cephalhematoma — bleeding beneath the periosteum, so it is confined to one bone and does not cross suture lines. It appears or enlarges over the first hours, feels firm, and resorbs over weeks. Because the trapped blood breaks down, these newborns are at higher risk for jaundice — a key nursing follow-up point.
• Subgaleal hemorrhage — bleeding in the loose space beneath the scalp that can spread widely. The swelling is diffuse, shifts with gravity, and can enlarge rapidly; pallor, tachycardia, and falling blood pressure signal significant blood loss. This is a medical emergency requiring immediate provider notification.

Skeletal and nerve injuries

• Clavicle fracture — the most common birth fracture, classically after shoulder dystocia or a large baby. The newborn may show "pseudoparalysis" (not moving that arm) and crepitus or swelling over the bone. Most heal well with supportive care and careful handling.
• Brachial plexus injury — stretching of the nerve network from the neck to the arm during difficult delivery of the shoulders. Erb's palsy involves the upper roots (C5–C6): the arm hangs adducted and internally rotated — the "waiter's tip" position. Klumpke palsy involves lower roots (C8–T1), affecting the hand, and can include an eyelid droop on the same side (Horner syndrome). Injuries range from mild stretch (neuropraxia) to nerve avulsion; most improve, and early positioning and gentle range of motion per provider/therapy guidance support recovery.
• Facial nerve palsy — pressure on the facial nerve, often from forceps or the maternal pelvis. The face is asymmetric: the affected side is flat, the eye may not close fully, and crying pulls the mouth to the other side. Usually transient; nursing care includes eye protection if the lid does not close, per orders.

Perinatal asphyxia and hypoxic-ischemic encephalopathy (HIE)

Perinatal asphyxia is the interruption of oxygen delivery around birth, leading to acidosis and impaired function of multiple organs. When the brain is affected, the result is hypoxic-ischemic encephalopathy, graded by severity (e.g., mild, moderate, severe) using tools like the Sarnat staging exam, which looks at level of consciousness, tone, reflexes, and seizures. Management is highly specialized — newborns with moderate/severe HIE may receive therapeutic hypothermia (cooling) in centers equipped for it, and every minute of recognition matters. The nurse's contribution is early recognition (poor tone, weak cry, apnea, seizures, poor perfusion) and immediate escalation.

Meconium aspiration syndrome (MAS)

When the fetus passes meconium (first stool) into the amniotic fluid — often in response to stress — and then gasps, meconium can be inhaled into the airways. MAS causes airway obstruction and inflammation, producing respiratory distress (fast breathing, retractions, grunting, low oxygen). Care is supportive and depends on severity; preventing further aspiration and close respiratory monitoring are the nursing priorities. Not every newborn in meconium-stained fluid develops MAS — the risk depends on how much was aspirated and the baby's condition at birth.

Transient tachypnea of the newborn (TTN)

TTN is "wet lung": delayed clearance of fetal lung fluid, most common after cesarean birth (no chest squeeze), rapid birth, or maternal sedation. The newborn breathes fast, often with mild retractions, within the first hours. It is self-limiting — fluid is absorbed over 24–72 hours — but it must be distinguished from more serious causes of respiratory distress (infection, MAS, surfactant deficiency), so evaluation follows the facility's respiratory pathway.

Metabolic effects of a stressful birth

Birth stress and the at-risk profile (large or small for gestational age, preterm, infant of a diabetic parent, cold stress, asphyxia) raise the risk of hypoglycemia and polycythemia. Blood glucose is monitored per protocol in at-risk newborns, and feeding is the first-line support; the specific thresholds and interventions follow provider orders. Jaundice risk rises after cephalhematoma, bruising, and polycythemia because extra red cells break down — another reason the nurse keeps the "trauma → jaundice" thread in mind.

How It Works / Step-by-Step Process

1. Review the birth record and flag risk factors: delivery mode, shoulder dystocia, macrosomia, meconium, fetal status, gestational age.
2. Perform a systematic newborn exam, paying extra attention to the scalp, clavicles, arm movement, and facial symmetry; observe for respiratory effort and tone.
3. Differentiate findings by anatomy and timing (caput vs. cephalhematoma vs. subgaleal) and document location, size, and changes precisely.
4. Monitor at-risk newborns per protocol: glucose, jaundice risk, respiratory status, neurologic observations.
5. Escalate red flags immediately — enlarging scalp swelling, pallor or instability, seizures, worsening respiratory distress — and follow orders.
6. Teach parents what was found, what it means, what to watch at home, and the follow-up plan; document everything.
