Which of the following is the least important prognostic factor in congenital diaphragmatic hernia ?

Timing of surgical repair has gradually shifted from an emergency repair, to a policy of stabilization using a variety of ventilatory strategies prior to operation. • Current recommendation is to adopt a conservative approach and delay surgical repair of the CDH until the infant stablizes from a hemodynamic and respiratory point of view. Prognostic factors in CDI-1 Prognostic factors can be divided into: (A) Primary prognostic factors (Pathophysiological) These are the most important prognostic factor which affect morbidity and mortility. These factors are: Pulmonary hypoplasia (most important) Pulmonary hypertension (2nd most important) (B) Secondary or relative predictors (diagnostic/clinical) These poor prognostic factors are: (a)      tinatal Detection at an early gestational age (<24 wks) Associated extradiaphragmatic congenital anomalies Liver herniation into thorax (Liver above diaphragm) Stomach herniationinto thorax (Stomach above diaphragm) Presence of polyhydraminios Small lung to head circumference ratio (LI-IR ratio) Small fetal abdominal circumference (< than 5th percentile) (b) Postnatal Early age (< 6 hours) of presentation PG, and PCO, unresponsive to ventilation Need for extracorporeal membrane oxygenation (ECM0) (c) Side of defect (i) Right sided defect
