Thanks for your query.
Alamine drip is an essential amino acid
drip given for intravenous hydration and nutrition if the fetus is growth restricted, or there is oligohydramnios
( decreased amount of amniotic fluid
surrounding the baby )
In absence of any such condition detected on ultrasound
or Colour Doppler , I fail to see the reason for advising Alanine drip.
Am sure your treating doctor would be able to elaborate the reasons for her decision better
