7.3 Nursing Care for Pediatric Emergencies and Acute Conditions

Introduction to Pediatric Emergencies

Pediatric emergencies require rapid assessment and precise intervention, as a child's physiological status can deteriorate quickly. A fundamental principle in pediatric emergency care is the systematic approach: Assess Airway, Breathing, Circulation, Disability, and Exposure (ABCDE), followed by targeted therapeutic measures.

Acute Pediatric Emergencies

Pediatric Poisoning

Accidental ingestion of toxic substances is a leading cause of pediatric emergency visits, especially in toddlers who are naturally curious and explore via the oral route.

• Immediate Management: The first step is to assess and stabilize the child's ABCs. Once stable, the nurse should obtain a focused history (what was ingested, how much, and when). The immediate next step is to consult the local Poison Control Center for specific guidance.
• Interventions: Gastric decontamination strategies have evolved. The routine use of Syrup of Ipecac to induce vomiting is no longer recommended due to the risk of aspiration and lack of proven efficacy. Depending on the toxin, activated charcoal may be administered to bind the substance in the GI tract, or specific antidotes (e.g., N-acetylcysteine for acetaminophen toxicity, naloxone for opioid overdose) may be used. If the ingestion involves a corrosive substance, vomiting must be strictly avoided as it causes further esophageal damage.

Foreign Body Aspiration (FBA)

Children between 1 and 3 years are at the highest risk for FBA due to their lack of molars for grinding food and tendency to run while eating. Common culprits include nuts, grapes, hot dogs, and small toys.

• Pathophysiology: Aspirated objects most frequently lodge in the right mainstem bronchus, as it is wider, shorter, and more vertically oriented than the left.
• Clinical Presentation: Sudden onset of coughing, choking, stridor, wheezing, or cyanosis. Unilateral diminished breath sounds are a strong indicator of FBA.
• Management: If the child is forcefully coughing, encourage them to continue. If the airway is obstructed (inability to speak or cry, cyanosis), initiate life support measures. For an infant, perform cycles of 5 back slaps and 5 chest thrusts. For an older child, perform abdominal thrusts (Heimlich maneuver). A rigid bronchoscopy is often required for definitive removal in the hospital setting.

Febrile Seizures

Febrile seizures are convulsions triggered by a rapid spike in body temperature, usually occurring in children aged 6 months to 5 years, often associated with a viral illness.

• Characteristics: Simple febrile seizures are generalized, last less than 15 minutes, and do not recur within 24 hours. They are generally benign and do not typically cause brain damage or lead to epilepsy.
• Nursing Management During the Seizure: Ensure safety. Lower the child to the floor, clear the area of hard objects, do not restrain the child, and never force anything into the child's mouth. Loosen tight clothing around the neck. Time the duration of the seizure. Turn the child onto their side (recovery position) to prevent aspiration of secretions.
• Post-Seizure Management: Reduce the fever with antipyretics (acetaminophen or ibuprofen; avoid aspirin) and treat the underlying infection. Provide immense emotional support and education to terrified parents, reassuring them of the benign nature of simple febrile seizures.

Congenital Anomalies

Tetralogy of Fallot (TOF)

TOF is a complex cyanotic congenital heart defect comprising four anatomical abnormalities:

1. Ventricular Septal Defect (VSD): A hole between the ventricles.
2. Pulmonary Stenosis: Narrowing of the pulmonary valve/artery.
3. Overriding Aorta: The aorta is shifted over the VSD.
4. Right Ventricular Hypertrophy: Thickening of the right ventricular wall.

• Clinical Presentation: Chronic cyanosis, clubbing of fingers, and poor weight gain. Children may experience acute hypoxic episodes known as "Tet spells" (Hypercyanotic spells), often triggered by crying, feeding, or defecating, which lead to increased right-to-left shunting of deoxygenated blood.
• Nursing Management for Tet Spells: The immediate nursing priority is to place the child in a knee-chest position (or encourage older children to squat). This increases systemic vascular resistance, decreasing the right-to-left shunt and forcing more blood through the pulmonary artery. Administer 100% oxygen via blow-by or face mask, and provide calming interventions. Morphine may be administered to decrease infundibular spasm and reduce oxygen demand.

Cleft Lip and Cleft Palate

These are congenital facial malformations caused by a failure of facial structures to fuse during embryonic development.

• Preoperative Care: The primary challenge is nutrition. The infant cannot generate a strong vacuum for sucking. Nurses should use specialized bottles (e.g., Haberman feeder), feed the infant in an upright position to prevent choking, and burp frequently due to excess air swallowing.
• Postoperative Care: Protect the surgical site. For cleft lip repair (cheiloplasty), utilize elbow immobilizers (restraints) to prevent the infant from scratching the face, and position the infant on their back or side, never prone. For cleft palate repair (palatoplasty), avoid placing rigid objects (straws, spoons, hard pacifiers) in the mouth. Meticulous suture care and pain management are vital to prevent crying, which places tension on the suture lines.
