Clinical Pathology, X-Rays, ECG
acute pul edema :
causes > AMI - ARDS - increased ICT - contusion - pneumonia
ttt > hospitalization - siiting position - IV drugs (morphine-
frusemide-Na nitroprusside-digoxin)
constrictive pericarditis :
ttt >>
ttt of cause > TB > rifampicin 10 mg/kg/day - isoniazid 10
mg/kg/day
symptomatic ttt > edema > frusemide 20-40 mg/day
