Management of Birth Asphyxia in Newborns
Initial Ventilation Settings
- For a 3kg newborn with birth asphyxia not maintaining oxygen saturation on hood, immediate intubation and mechanical ventilation should be initiated with initial settings of PIP 20-25 cmH2O, PEEP 5 cmH2O, rate 40-60 breaths/min, and starting with 21-30% oxygen titrated by pulse oximetry, as recommended by the American Academy of Pediatrics 1, 2
- Initial ventilator settings should include Peak Inspiratory Pressure (PIP) of 20-25 cmH2O, as suggested by the American Academy of Pediatrics 4, 3
- Positive End-Expiratory Pressure (PEEP) should be set at 5 cmH2O, according to the American Academy of Pediatrics 4
- Respiratory Rate should be set at 40-60 breaths/minute, as recommended by the American Academy of Pediatrics 5
- FiO2 should start with 21-30% and be titrated based on pulse oximetry, as suggested by the American Heart Association 1, 2
Oxygen Management
- Pulse oximeter should be attached to the right upper extremity to guide oxygen titration, as recommended by the American Heart Association 6, 7
- Target oxygen saturation levels should be similar to those of healthy term newborns, initially 60-65% at birth, gradually increasing to 85-95% by 10 minutes, according to the American Academy of Pediatrics 6
- Oxygen concentration should be carefully titrated to avoid both hyperoxemia and hypoxemia, as suggested by the American Academy of Pediatrics 2, 5
Circulatory Support
- Heart rate should be monitored continuously, as it is the most sensitive indicator of resuscitation efficacy, according to the American Heart Association 2, 5
- If heart rate remains below 60 bpm despite effective ventilation, chest compressions should be initiated using the 2-thumb, hands-encircling-the-chest method, as recommended by the American Heart Association 1
- A 3:1 compression-to-ventilation ratio should be used, as suggested by the American Heart Association 1, 6
Medication Management
- If heart rate remains below 60 bpm despite effective ventilation and chest compressions, epinephrine 0.01-0.03 mg/kg IV should be administered, as recommended by the American Heart Association 6, 7
- Volume expansion with normal saline 10 ml/kg should be considered if signs of hypovolemia are present, according to the American Heart Association 6
Monitoring and Assessment
- Exhaled CO2 detection should be used to confirm endotracheal tube placement, as recommended by the American Academy of Pediatrics 3
- Vital signs, including heart rate, oxygen saturation, and blood pressure, should be monitored continuously, according to the American Academy of Pediatrics 2, 5
- Neurological status should be assessed frequently, as suggested by the American Heart Association 6
Post-Resuscitation Care
- Therapeutic hypothermia should be considered for moderate to severe hypoxic-ischemic encephalopathy, as recommended by the American Heart Association 6, 7
- Cooling should be initiated within 6 hours of birth under clearly defined protocols, according to the American Heart Association 6
- Multidisciplinary care should be maintained in a neonatal intensive care unit, as suggested by the American Heart Association 6
Common Pitfalls to Avoid
- 100% oxygen should not be used for initial resuscitation, as it provides no advantage over air and may increase oxidative injury, according to the American Heart Association 1, 2
- Excessive ventilation should be avoided, as it can lead to lung injury and decreased cerebral blood flow, as suggested by the American Academy of Pediatrics 4, 3
- Delays in initiating therapeutic hypothermia should be avoided when indicated, according to the American Heart Association 6
- Color should not be relied on as an indicator of oxygenation; pulse oximetry should be used instead, as recommended by the American Academy of Pediatrics 2, 5
