Abstract
PPHNS is a disorder charactarized by increased pulmonary ascular resistance producing elevated pulmonary artery pressure, right to left shunting of deoxygenated blood across the patent ductus arteriosus and , or foramen ovale, and severe systemic hypoxemia (Walker, 1990). The aim of this study is to identify the magnitude of the problem of PPHNS in Mansoura NCD and to demonestrate its epidemiological association preparing for initiation of a skeleton for management. Each case was subjected to the following:- l) Careful antenatal and neonatal history . 2) Careful clinical examination. 3) Arterial blood gases. Pre ductal (right radial) . Postductal (umbilical or femoral) . 4) Transcutaneous 02 saturation (oximetry) over the upper right chest and the lower part of the body. 5) Chest x ray . 6) Electrocardiogram. It is to be noted that serial diffrential arterial blood gases were done for each case till improvement of PPHNS or death .
