Abstract

SUMMARY
Neonatal cyanosis is not uncommon in the newborn
infants. Cyanosis in newborn infants is a medical
emergency requiring quick action.
Cardiac abnormalities are the common cause of
cyanosis in the newborn infants, when cyanosis occure
in a newborn infant and is found to be due to a cardiac
anomaly, the abnormality is usually a complex one. In
the neonatal period, the most common cause of cardiac
cyanosis is due to complete transposition of great
arteries.
Pulmonary disorders and primary lung diseases
are alse common causes of cyanosis in the newborn infants.
Attention to the central nervous system abnorma-
Li,ties must be anticipated as they represent the third
common cause of cyanosis in the newborn. Neonatal shock
and septicemia represent also a great concern.
Rarely, hematological abnormalities (methemoglobinemia
and neonatal polycythemia) or, neonatal hypoglycemia
represent a major consideration.
Cyanosis in the newborn infants is a diagnostic
challenge to the general pediatrician. However, hyperoxia
test provides arrational and systematic approach for
differential diagnosis of most causes however, the
potential toxicity of oxygen must be considered.

Echocardiography and computerized tomography represent
important diagnostic tools in the evaluation of
cyanotic newborns.
Often in the past, these babies have been placed
in oxygen hoping that they would improve.
Now, with the ability to offer treatment with
hope for survival, intial recognition and appropriate
management is mandatory. Medical and surgical management
has undergone major changes in the last few years.
Lastly, our work show that the prompt recognition
and appropriate referral of cyanotic newborn infants
should result is excellent long-term prognosis for the
vast majority of these infants.
