We routinely put 10 units in 500-100cc LR (whatever is left in bag from labor- if there is less than 55, I will mix a fresh bag) and open the fluid, at delivery of placenta, until bleeding is under control. If bleeding is heavy, we will add another 10units, but that is MD call, not nursing! The initial 10 units is also MD call, not nursing, but it is expected and we always have it ready to go. Once bleeding is controlled and uterus is nice and firm, I will slow the fluids to about 125cc/hr. Hope this helps! Joyce
