Intrauterine resuscitation, how long for effect?

Published

Hi all!

Does anyone know how long it takes for the most common attempts at intrauterine resuscitation to affect fetus? I believe that position change should be immediate (if it's going to work), but what about fluid bolus, tocolytics and O2 therapy? Any references or links to sources would be very cool......

Thanks! SG

I have found that most of the time, you will see improvement (if there will BE any) within 5-10 minutes after tocolysis and fluid resuscitation. This is just anecdotal experience, mind you.

O2 I usually see an improvement almost immediately (maybe within 2-3 UCs). Fluid resuscitation, maybe 5-10 minutes. Tocolysis - however long it would take for UCs to stop (so 10-20 minutes). JME.
