Hi , Dr Khaled,
Welcome to HCM.
You can definitely go for Dicynone
( Etamsylate) to halt the on going GI bleeding. I think you know the dose to be given in neonates ( 12.5mg/kg body weight every 6th hrly).
If the child is on ryle's tube, infusing cold
normal saline though ryles's tube shall help in controlling GI bleeding in some cases ( can be tried in emergencies . Succesfully tried personally in few cases).If possible try to confirm whether the bleeding is of variceal or non variceal in origin. You can perform a bed side Ulatrsonogram.
Hope the baby recovers soon.
