OSPE PEADS MEDICINE
Case 1 The child presented with history of cyanosis since birth.
Look at the picture & answer the questions.
1. What is this condition called?
2. In which disease it is seen?
3. How will you treat the attack seen in the picture?
OSPE Peads Medicine SurgicoMed.com
Key
1. Tet Spell (Paroxysmal Hypercyanotic Spell)
2. Tetralogy of Fallot (TOF)
3. Treatment plan is as;
Hospitalization
Place the child in lateral knee-chest position
Oxygen inhalation
Subcutaneous Morphine sulphate
Propranolol
I/V Na-Bicarbonate to correct acidosis
Note 1. Tet spell is a problem during first 2 years of life in TOF. The infant becomes hyperapneic
& restless. Cyanosis increases and grasping respiration occurs. If severe may lead to
Syncope. The spell mostly occurs when child wakes up in the morning or after sleep or
during crying. During the attack, systolic murmur disappears.
2. Cardio-protective shunts (improve oxygenation if along TOF) like ASD, PDA.
