A couple of days ago we had a patient in OT who had a major obstetric haemorrhage and required 12 units of blood. Unfortunately she was O negative and because of the shortage of O negative blood, 8 of these units were O positive. She eventually had a hysterectomy and seemed to recover okay.

Lcsmrz

She is not likely to develop an Anti-D so quickly. I would continue giving O Pos red cells, especially since there is no chance for another pregnancy.

Likewine99

I agree with Lcsmrz. I have also seen this done with massively bleeding, female open heart patients.

YorkshireExile

Thanks for the replys. Our transfusion - happy doctors have not decided to transfuse yet so everything is okay at the moment. They will probably decide to transfuse in the middle of the night and I will have to be woken up to explain to them why its okay to still give O Pos blood.

John C. Staley

You may want to explain the situation to them now. It will give them something to think about and may consider the need to transfuse much more closely than they would other wise. Over the years we have discovered that if you are prepared for the worst it seldom if never happens. It only seems to happen when you are not prepared.

David Saikin

We would always continue to transfuse Rh+ red cells. I don't think I ever had a patient get sensitized that received an overwhelming volume of the +blood. It is when you only give one or two that they make the antibody (maybe throw in a couple of + plts too).

pluto

We caused panic on ward recently by issuing 4 units RhD Pos to male nearly 80years old who was RhD negative and bleeding, actually refused to use it . his Hb was ok in end and received no transfusions . very frustrating when trying to conserve RhD Neg and we will be focussing again training in this area
