Paramedic: Neonatal Complications 2
This lesson continues the discussion on neonatal complications, focusing on the acute care of conditions like hyperthermia, birth injuries, and the crucial aspects of thermoregulation in newborns. Paramedics must understand these unique challenges for effective prehospital management.
Neonatal Hyperthermia (Fever)
A fever in a neonate (rectal temperature > 38°C or 100.4°F) is a significant concern and often indicates a potential infection.
Unique Challenge: Newborns may not always present with classic fever signs due to their immature immune system.
Risks: Increased metabolic rate, reduced blood glucose, increased oxygen and fluid consumption, leading to hypoxia and hypoglycemia.
Assessment:
Obtain vital signs, ensure adequate oxygenation and ventilation.
Assess for circulatory status, hypoxia, and hypoglycemia.
Examine for rashes (e.g., petechial/purpuric rashes can indicate meningitis).
Note bulging fontanelle (increased intracranial pressure).
History from caregivers regarding changes in behavior, feeding, and activity.
Management:
Supportive care: Maintain ABCs.
Do not actively cool aggressively, but unbundle the infant if excessively warm (remove hats, blankets).
Administer antipyretics (e.g., acetaminophen) per protocol if indicated.
For advanced providers, IV fluids may be considered.
Be vigilant for seizures and manage them per protocol (e.g., benzodiazepines, or magnesium sulfate for pregnant patients if fever is associated with eclampsia).
Rapid transport to an appropriate facility for full sepsis workup if infection is suspected.
Neonatal Birth Injuries
Newborn injuries can occur due to the newborn's size, position during delivery, or complications during the birthing process. Most are self-limiting, but some require specific interventions.
Head Malformations/Trauma:
Molding: Normal process where the skull bones overlap to facilitate passage through the birth canal. Usually resolves within a few days.
Caput Succedaneum: Swelling of the scalp, crosses suture lines. Resolves spontaneously.
Cephalhematoma: Collection of blood under the periosteum, does NOT cross suture lines. May take weeks or months to resolve.
Skull Fractures: Linear fractures are most common, often benign. Depressed skull fractures are more serious.
Management: Assess for signs of increased intracranial pressure (bulging fontanelle, altered mental status, Cushing's triad). Careful monitoring. Transport for neurosurgical evaluation if severe.
Brachial Plexus Injuries (e.g., Erb's Palsy): Damage to the nerves of the brachial plexus (C5-T1), often due to shoulder dystocia or excessive traction during delivery.
Presentation: Lack of movement, weakness, or paralysis in the affected arm/hand.
Management: Gentle handling, immobilize the arm across the body. Refer for specialist evaluation.
Clavicle Fracture: Most common fracture during childbirth.
Presentation: Palpable bony irregularity or crepitus over the collar bone, lack of arm movement, pain with movement.
Management: Gentle handling, immobilize arm to the body (e.g., sling and swathe). Transport for evaluation.
Facial Nerve Palsy: Unilateral facial droop due to compression of the facial nerve (CN VII) during delivery. Usually resolves spontaneously.
Diaphragmatic Paralysis: Can occur from injury to the phrenic nerve (C3-C5), leading to respiratory distress.
Spinal Cord Injury: Rare but devastating, often due to excessive traction or hyperextension/hyperflexion of the neck.
Long Bone Fractures: May present as loss of spontaneous arm or leg movement.
Intra-abdominal and Thoracic Injuries: Relatively uncommon but can be severe. Be vigilant for signs of pneumothorax or internal bleeding.
Birth Asphyxia and Hypoxia
Hypoxia and shock can be caused by birth trauma or other complications.
Assessment: Assess for signs of respiratory distress, cyanosis, poor tone, bradycardia, and poor perfusion.
Management: Aggressive airway management, ventilation, and oxygenation. Treat shock with fluid boluses as needed (judiciously in cardiogenic shock).
Apparent Life-Threatening Events (ALTEs) / Brief Resolved Unexplained Events (BRUEs)
Episodes where an infant becomes pale or cyanotic, has an apneic spell, or loses muscle tone, which resolves spontaneously.
Concern: Can be a precursor to SIDS (Sudden Infant Death Syndrome) or an indication of an underlying issue.
Assessment: Thorough history from caregivers (duration, character of event, associated symptoms). Evaluate for underlying causes (e.g., reflux, seizures, infection).
Management: All infants who experience an ALTE/BRUE require transport and evaluation at a facility, even if they appear normal on arrival.
Critical Thinking Questions
You are called to a 5-day-old infant with a rectal temperature of 38.5°C (101.3°F), appearing lethargic and feeding poorly. What is your primary concern, and what critical interventions are needed in the prehospital setting?
During a difficult breech delivery, you notice the newborn's arm is flaccid and externally rotated with an inability to move the shoulder. What is the suspected injury, and how would you manage it?
A caregiver describes an episode where their 2-month-old infant suddenly became pale, stopped breathing briefly, and then spontaneously recovered. The infant now appears normal. How should you approach the assessment and what is your transport recommendation?
Explain why birth injuries that cause hypoxia or shock require immediate and aggressive management, and how this differs from managing similar conditions in adults.
Discuss the importance of a detailed history regarding feeding, vomiting, and stool characteristics when assessing a neonate for gastrointestinal complications, and how this guides your suspicion for specific conditions.
