Post HIE rehabilitation

We recently had a newborn( Term, 3.9 kg)brought from nearby hospital with ET in situ after sudden apnoea . She had no cardiac activity.needed 3 boluses of adrenalin followed by 40 ml /kg NS (twice) After 20 mts CPR heart rate picked up , colour returned and baby needed mechanical ventilation for 3 days. Now in nasal o2. Baby had congenital pneumonia and PDA. Neurosonogram today normal. Had an episode of seizure on day 1,controlled with phenobarbitone.

My questions are;

1. when do you start rehabilitation programme?and how do you do it?

2. Can we start gentle exercises for the limbs early on?

3.Do we have any structured programme to follow ?

4.investigations to prognosticate developement and long term issues?

Your input is valuble.

thanks
