Early management of PDA dependant CHD Severe acute cyanosis < 70 % or circulatory collapse in the 1 st week of life indicate cyanotic or Lt sided obstruction PDA dependant CHD respectively. Severe acute cyanosis < 70 % or circulatory collapse in the 1 st week of life indicate cyanotic or Lt sided obstruction PDA dependant CHD respectively. Examples are pulmonary atresia and d-TGA for cyanotic and critical COA or IAA. For obstructive Lt sided CHD. Examples are pulmonary atresia and d-TGA for cyanotic and critical COA or IAA. For obstructive Lt sided CHD. The PDA provides the needed PBF, MIXING,or SBF. for these lesions. The PDA provides the needed PBF, MIXING,or SBF. for these lesions.

PDA dependant CHD Our aims in these pts are ; Our aims in these pts are ; 1) Keep ductal patency by PGE through a secure venous line. 1) Keep ductal patency by PGE through a secure venous line. 2) Maintane saturation 75—80 % in RA even if ventilated to avoid induction of CHF 2 nd to increased PBF with decreasing PVR. 2) Maintane saturation 75—80 % in RA even if ventilated to avoid induction of CHF 2 nd to increased PBF with decreasing PVR. 3) Avoid pulmonary vasodilation. 3) Avoid pulmonary vasodilation.

PDA dependant CHD 4) Avoid fluid overload. 5) Avoid infection. 6) Early intervention or surgery within 2-7 d. 7) Provide a mixing or loading site.( d-TGA & HLHS ). 8) Aggressive correction of metabolic acidosis.

Conclusion Knowing the pathophysiology and natural history of outcome is essential in the management of CHD. Knowing the pathophysiology and natural history of outcome is essential in the management of CHD. Most CHD pts can be managed as OPD in the community provided there is a clear plan set between the primary pediatrician and the cardiologist. Most CHD pts can be managed as OPD in the community provided there is a clear plan set between the primary pediatrician and the cardiologist. More exposure of ped. Trainees to CHD medical therapy & surgery and to the ICU care these pts need will help in increasing the successful early management of CHD BY the pediatrician. More exposure of ped.
