2 CYANOSIS IN CHILDREN
- Central cyanosis
- Cyanosis of the tongue,mucous membranes and
peripheral skin, it is necessary to have gt3g/dl
of reduced Hb to have it. - Peripheral cyanosis
- It is visible only in the skin of the extremities
with normal arterial saturation due to vasomotor
instability,ex. cold environment.
3 CAUSES OF CENTRAL CYANOSIS
- Congenital Heart Disease
-
- 1) Cyanosis with PBF 2) Cyanosis
with PBF -
- a) TOF
a) D-TGA - b) Pulm. Atresia b)

5RADIOLOGICAL FEATURES
- CXR may exclude non cardiac causes of cyanosis
e.g. RDS. . Meconium aspiration, Diaphgramatic
hernia, Pneumothorax - Pulmonary Vascular Markings
- Decreased

6ECG
- RV dominace on ECG is normal in the newborn.
-
- Left axis deviation with LVH strongly suggests
- Tricuspid Atresia.
- Left axis deviation in a newborn may also
indicate - AV canal
- ( However , AV canal is usually an
acyanotic - form of heart disease).
-
7Blood gases response to 100 O2
- Always try to obtain ABG from RIGHT radial
artery. - Low PH may indicate sepsis, circulatory shock or
- severe hypoxia
-
- High pCO 2 may indicate CNS or pulmonary
disease. -
- Hyperoxia Test 100 O2 by hood for 10 minutes.
-
- pO2 gt 150 torr pulmonary disease.
- pO2 lt 100 torrcyanotic heart disease

36AUSCULTATION
- HEART SOUNDS
-
- S1 is normally accentuated in newborns
-
- S2 split is normally heard as a slurring rather
than a distinct split. - S2 is single in many cyanotic lesions especially
in, D-TGA, TOF. -
- S2 is widely split in TAPVR, Critical PS.
-
37MURMURS
- SYSTOLIC EJECTION MURMURS
- May be heard in the first hours of life.
- Usually due to ventricular obstruction e.g.
AS., PS., TOF -
- DIASTOLIC MURMURS
- Rarely heard in newborns
- Early diastolic murmurs heard in Truncus
arteriosus , - TOF with absent pulmonary valve
-
- Continuous
- Continuous murmurs are caused by AV fistulas
- (not PDA)
- ABSENT
- Silent hearts often characteristic of
Tricuspid atresia , Pulmonary atresia D-TGA. -

53 CYANOSIS IN CHILDREN
- Cyanosis depends not only on O2 saturation but
also on absolute concentration of reduced Hb. - Fetal Hb Neonates have serious reduction in pO2
before cyanosis is clinically apparent. - DIFFERENTIAL CYANOSIS
- Upper body PINK, lower body BLUE
- PRE-ductal COA ( RV supplying Dao via PDA)
- Upper body Blue, lower Pink
- D-TGA with PDA and COA ( LV supplying Dao via
PDA).
