Study Notes
Cardiac Rhythm and Conditions
- SVT can convert to sinus rhythm following adenosine administration.
- Sinus bradycardia is characterized by a heart rate less than 60 bpm.
- Normal sinus rhythm indicates a heart rate of 60 to 100 bpm with regular intervals.
- Asystole denotes a flatline, representing no electrical activity in the heart.
- Wide complex tachycardia presents with a heart rate typically over 100 bpm and widening of QRS complexes.
- Torsades de pointes is a specific form of polymorphic ventricular tachycardia associated with a prolonged QT interval.
- Supraventricular tachycardia originates above the ventricles; it typically presents with a rapid heart rate.
- Ventricular fibrillation is a life-threatening arrhythmia requiring immediate defibrillation to restore rhythm.
Pediatric Emergency Assessment
- An infant presenting with weak pulses (capillary refill over 5 seconds) and hypoglycemia (glucose 30 mg/dL) should receive isotonic crystalloid bolus and dextrose.
- In asthmatic children in respiratory distress, administering Albuterol is crucial for bronchodilation.
- A 1-year-old child in critical condition showing bradycardia (HR 36/min) and cyanosis requires immediate fluid resuscitation with isotonic crystalloid.
- For severe symptomatic bradycardia in infants, Epinephrine should be the primary medication if effective airway management fails.
Resuscitation and Drug Administration
- Calcium chloride use in pediatric cardiac arrest is not typically recommended unless specific indications arise.
- Endotracheal drug administration during resuscitation is considered the least desirable route due to variable absorption.
- Initial management of a 2-year-old with mild inspiratory difficulty involves administering humidified oxygen to relieve symptoms.
- During resuscitation for ventricular fibrillation, if epinephrine is administered after two shocks, Amiodarone should follow at a dosage of 5 mg/kg if rhythm persists.
Oxygen Delivery Systems
- Various oxygen delivery systems are utilized in different clinical scenarios, ensuring adequate oxygenation tailored to patient needs.
