|Cyanosis resident survival guide (pediatrics) Microchapters|
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
- Patients presenting to the emergency department with cyanosis and respiratory distress require emergency supplementation of oxygen, use of pulse oximetry and airway, breathing, and circulation support.
- A Focused Initial Rapid Evaluation (FIRE) should be performed to identify the patients in need of immediate intervention.

Complete Diagnostic Approach
- Shown below is an algorithm summarizing the diagnosis of cyanosis in newborns according to the American Academy of Neonatology guidelines:

|Diagnostic Studies |
- Hypoplastic left heart syndrome in infants should be considered with signs and symptoms such as:
- In Ebstein anomaly, repair of tricuspid valve is indicated if the following criteria is met:
- In differential cyanosis, if oxygen saturation of right arm is more than that of legs and improves with oxygen supplemental therapy, then think about the following:
- In the presence of central cyanosis + hemolytic anemia (jaundice, heinz body, fragment RBC) + renal failure, consider diagnosis of methemoglobinemia and treat accordingly.
- Hydration is important in tetralogy of fallot to maintain pulmonary blood flow through atretic pulmonary artery and reducing right to left shunt through VSD.
- If paradoxical embolism is suspected, proceed with a Brain CT scan in the presence of new neurological symptoms in a patient with cyanotic congenital heart disease. It occurs due to passing of emboli from right to left shunt and hyperviscosity ultimately leading to thrombosis.
- There are certain cyanotic congenital heart diseases that are dependent on patent ductus arteriosus (PDA). Don't give indomethacin to patients with the following ductal dependent congenital conditions:
