Greetings from Ecuador. We use paracetamol protocol to close de PDA instead of indometacin (15 mg/k/dose every 6 hours for three days). Also the use of epineprine for the pulmonary hemorrage. My suggestion is to add a new dosis from Vitamin K1 IV and check For Pulmonary hypertension may be you need sildenafil.
