DDVP and Platelet Reversal

If there's no hematoma expansion we're not going to be giving platelets. DDVP again there's more emerging literature on DDVP some of the earlier studies just had very small numbers so we haven't seen any safety concerns with DDVP. For patients who are going to undergo a surgical procedure specifically if they they have intra ventricular hemorrhage and they need an EDG. It's again case by case depending upon whether those patients have underlying papatoreneal dysfunction or not.
