Management of Congestive Cardiac Failure in Neonates

Initial Assessment and Monitoring

The European Society of Cardiology recommends rapid nursing assessment to optimize triage to the appropriate level of care and inform the management plan 1
Continuous monitoring of heart rate, respiratory rate, oxygen saturation, blood pressure, and neurological status is crucial, with heart rate being the most sensitive indicator of resuscitation efficacy 1, 2
Laboratory assessments should include troponin, BUN, creatinine, electrolytes, glucose, and complete blood count, as well as arterial or venous blood gases to assess pH and CO2 levels 3

Positioning the infant upright can improve respiratory mechanics, and oxygen therapy should be provided to maintain SpO2 >90% 1, 3
Consider Continuous Positive Airway Pressure (CPAP) or Pressure Support-Positive End-Expiratory Pressure (PS-PEEP) if respiratory distress persists, with initial settings of Peak Inspiratory Pressure (PIP): 20-25 cmH2O, Positive End-Expiratory Pressure (PEEP): 5 cmH2O, Respiratory Rate: 40-60 breaths/min, and FiO2: 21-30% 1, 2, 3

Administer intravenous diuretics, such as furosemide 1-2 mg/kg/dose IV, and monitor renal function and electrolytes daily 1, 4
Consider epinephrine 0.01-0.03 mg/kg IV if heart rate remains below 60 bpm despite effective ventilation and oxygenation 2
Volume expansion with normal saline 10 ml/kg should be considered if signs of hypovolemia are present 2

Weigh the infant daily and maintain an accurate fluid balance chart, and monitor renal function with daily measurement of urea, creatinine, and electrolytes 4
Ensure adequate caloric intake, with consideration of sodium supplementation of 1-2 mmol/kg body weight/day, especially in exclusively breastfed infants 5

Evaluate for underlying causes of CCF, such as congenital heart defects or arrhythmias, and consider echocardiography to assess cardiac structure and function 6, 7
Consider consultation with pediatric cardiology for specialized management, and evaluate for pulmonary hypertension 4, 6

Patients should only be discharged when hemodynamically stable and euvolemic for at least 24 hours, established on appropriate oral medications, and with stable renal function 4
Follow-up plans must be clearly communicated to the primary care team, with early follow-up within 1-2 weeks after discharge 4

Avoid excessive oxygen administration (hyperoxia) and excessive ventilation, as they can lead to oxidative injury and lung injury, respectively 2
Do not rely on color as an indicator of oxygenation; use pulse oximetry instead, and avoid sedative medications and central nervous system depressants as they may worsen respiratory status 2, 8
