Prehospital Academy Lesson 39.8
Neonatal Complications 1 of 2
This lesson focuses on common neonatal complications and emergencies, providing paramedics with critical knowledge for recognizing and managing these conditions in the field. Newborns and neonates present unique challenges due to their immature physiology and rapid deterioration potential.
Neonatal Seizures
Seizures in newborns suggest the presence of an underlying neurological disorder. Prolonged seizures and corresponding hypoxia can cause significant brain injury.
Types: Myoclonic, spasmodic, tonic, and subtle seizures.
Presentation: Can be focal or generalized, stimulus-sensitive. May not always present as generalized tonic-clonic activity. Subtle signs include staring, rhythmic eye blinking, lip smacking, or bicycling movements.
Differential Diagnosis: Apparent Life-Threatening Events (ALTEs) can mimic seizures.
Assessment:
Evaluate prenatal and birth history.
Physical exam, vital signs.
Assess blood glucose levels: Hypoglycemia (blood glucose < 40 mg/dL) is a common, treatable cause of neonatal seizures.
Management:
ABCs: Provide additional oxygen and ventilation assistance as needed.
Hypoglycemia: Administer IV bolus of Dextrose 10% (D10) (typically 2 mL/kg). NEVER use D50 in neonates due to osmolarity and risk of intracranial hemorrhage.
Temperature: Maintain normal body temperature; keep the room warm.
Transport: Rapid transport to a facility with pediatric/neonatal capabilities. Communication with the receiving facility is paramount.
Neonatal Hypoglycemia
Hypoglycemia in the neonate can result in seizures and subsequent brain damage. Newborns and infants have limited glycogen stores and cannot compensate for hypoglycemia as effectively as adults.
Definition: Blood glucose < 40-45 mg/dL (varies slightly by age, e.g., <25 mg/dL in first 4 hours).
Risk Factors: Prematurity, maternal diabetes, perinatal stress, sepsis, hypothermia, decreased glycogen storage.
Symptoms: Can be non-specific (lethargy, irritability, poor feeding, apnea, cyanosis, jitteriness, hypotonia) or severe (seizures).
Management:
ABCs: Ensure adequate oxygenation and ventilation.
Glucose: Encourage feeding (breast milk/formula) if alert and able to swallow. If IV access is available, administer IV bolus of D10 (2 mL/kg).
Temperature: Maintain normal body temperature.
Neonatal Vomiting and Diarrhea
Common in newborns, but can quickly lead to dehydration and electrolyte imbalances.
Vomiting:
Persistent or Bilious Vomiting: Especially in the first 24 hours, can indicate upper digestive tract issues (e.g., esophageal atresia, malrotation, pyloric stenosis).
Sudden, Forceful Vomiting: Can occur with increased intracranial pressure (ICP), meningitis, hydrocephalus, or head trauma (abuse/neglect).
Assessment: Assess for dehydration, fever, temperature instability, abdominal distention, abdominal tenderness/guarding, signs of increased ICP.
Management:
ABCs: Supportive care.
Gastric Decompression: Consider inserting an orogastric (OG) or nasogastric (NG) tube for decompression (if protocols allow).
Fluid Resuscitation: May be needed for dehydration.
Positioning: Place newborn on their side during transport to prevent aspiration.
Anti-emetics: Generally avoided in neonates unless specifically indicated and approved by medical control.
Diarrhea:
Causes: Gastroenteritis, lactose intolerance, poisoning, neonatal abstinence syndrome.
Assessment: Estimate volume loss (ask caregivers about frequency/size of bowel movements, number of wet diapers). Assess for decreased urinary output, lethargy, sunken fontanelle.
Management: Fluid resuscitation for dehydration. Address underlying cause.
Neonatal Jaundice
Physiological jaundice is common, but pathological jaundice requires intervention.
Definition: Typically visible in the first 24 hours of life if pathological, or when serum bilirubin > 5 mg/dL. Clinical jaundice persisting >1 week (full-term) or >2 weeks (pre-term) is concerning.
Assessment: Evaluate skin, sclera, and mucous membranes for yellow discoloration. Assess hydration status, feeding patterns.
Management: Transport is essential for further evaluation and treatment (e.g., phototherapy, exchange transfusion). Paramedics may consider starting IV fluids if dehydration is significant and clinical jaundice is severe, in communication with medical control.
Neonatal Hypothermia and Fever
Newborns have limited thermoregulation capabilities and are highly sensitive to environmental conditions.
Hypothermia (<35°C / 95°F):
Presentation: Pale, acrocyanosis, cool to touch, decreased respiratory effort, bradycardia. May indicate infection.
Management:
Warm hands before contact.
Dry baby thoroughly after birth.
Place pre-warmed cap on head.
Maintain warm environment (turn up ambulance heat).
Skin-to-skin contact with mother is excellent for warming.
Glucose: Treat hypoglycemia with D10 IV bolus if present.
Fever (>38°C / 100.4°F rectal):
Presentation: Newborns may not always present with classic fever signs due to immature immune systems.
Concerns: Increased metabolic rate, reduced blood glucose, increased oxygen/fluid consumption. May indicate serious infection (sepsis).
Management:
Obtain vital signs, ensure adequate oxygenation and ventilation.
Do not actively cool aggressively, but unbundle if excessively warm (remove hats/excess blankets).
Assess for rashes, signs of sepsis, altered mental status, poor feeding.
Transport to definitive care for full sepsis workup if suspected.
Birth Injuries
Most are self-limiting, but some can be severe.
Cephalhematoma/Caput Succedaneum: Swelling/bruising on the head; usually resolve spontaneously.
Skull Fractures: Linear fractures are most common, often benign. Depressed fractures are more concerning.
Brachial Plexus Injuries: (e.g., Erb's Palsy) Damage to nerves innervating the arm/hand, often from shoulder dystocia.
Clavicle Fracture: Most common fracture during childbirth; may present with crepitus and lack of arm movement.
Facial Nerve Palsy: Unilateral facial droop.
Hypoxia/Shock: Can be caused by severe birth trauma.
Assessment: Palpate for bony irregularities, assess arm/leg movement, note any deformities. Convey all findings to receiving facility.
Critical Thinking Questions
You are called to an unresponsive 3-day-old neonate with subtle seizure-like activity. The blood glucose is 30 mg/dL. What immediate pharmacological intervention is indicated, and why should D50 be avoided?
A 10-day-old infant presents with persistent, forceful, projectile vomiting. What serious gastrointestinal condition should you consider, and what are the prehospital management priorities?
An infant is presenting with jaundice that started within 12 hours of birth. What type of jaundice is this, and why is rapid transport to a definitive care facility crucial?
You are treating a hypothermic newborn with a rectal temperature of 34°C. Besides external warming, what other metabolic complication are you particularly vigilant for, and how would you manage it?
During your assessment of a newborn who was a difficult delivery, you palpate a bony irregularity along the clavicle and note decreased movement of the left arm. What is the most likely birth injury, and what is your prehospital management?
