Overview

Cyanosis can be defined as bluish discoloration of skin and mucosa and can also be a manifestation of oxygen desaturation of arterial or capillary blood. Cyanosis, hypoxemia, and hypoxia should be differentiated and can occur independently. The causes of cyanosis in a newborn range from congenital cardiac conditions to life-threatening conditions such as exposure to toxic gases or infections leading to sepsis. The management of cyanosis depends upon the etiology and emergent cases with respiratory distress need rapid evaluation and response with immediate establishment of airway access and oxygen support.

FIRE: Focused Initial Rapid Evaluation

  • A Focused Initial Rapid Evaluation (FIRE) should be performed to identify the patients in need of immediate intervention.[3]

Treatment

 
 
 
 
 
 
 
Treatment Depends upon the etiology of cyanosis.

No Respiratory Compromise
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
*An adequate airway should be established and supplemental oxygen is given.
  • Continuous positive airway pressure (CPAP) or intubation for positive pressure ventilation can be done for infants with respiratory distress and carbon dioxide retention.
  • If there is airway obstruction prone positioning or oral airway is established to relieve cyanosis.
 
 
 
 
 
 
 
Depending upon etiology
  • Sepsis : Broad-spectrum antibiotics should be initiated such as ampicillin and gentamicin.
  • Blood cultures should be obtained to identify the causative agent.

    • Neonatal Hypoglycemia : Adequate blood glucose should be maintained in range of >45 to 50 mg/dl
    • Cyanotic Congenital Cardiac Conditions should be approached with proper pediatric consultation.
    • Prostaglandin E1 should be infused at 0.01-0.05mcg/kg/min.
