early cord clamping and cutting gentle cord traction with uterine
countertraction when the uterus is well contracted (ie, Brandt-Andrews maneuver).

Two important facts…1. Caregivers consistently underestimate visible
blood loss by as much as 50%. The volume of any clotted blood represents half of the blood volume required to form the clots.
2. Most women giving birth are healthy and compensate for blood loss very well. This, combined with the fact that the most common birthing position is some variant of semirecumbent with the legs elevated, means that symptoms of hypovolemia may not develop until a large volume of blood has been lost

Resuscitation…Administer 5-7L/min of Oxygen by face maskPlace 2 large bore IV linesInitial Blood work:
Type and cross match, CBC, PT/PTT/INR, Fib, FSP, Cr, S-8
Fluid Resusciation with NS or LR to maintain BP at 90 mm/Hg
Blood transfusion using Massive Transfusion Protocol
Correct coagulopathy if present
![Page 17: Old Problem – Consistent Thoughts Definition… Arbitrary and problematic Traditionally: ( Baskett, 1999) EBL >=500 cc after vaginal delivery EBL >=1000](https://reader030.vdocuments.us/reader030/viewer/2022032517/56649c9e5503460f9495ea22/html5/thumbnails/17.jpg)
Consider activation of a MT protocol when patient actively bleeding and any of the following:
Systolic blood pressure < 90 mmHg Ph < 7.1 Base deficit > 6 meq/L Temperature below 34°C INR > 2.0 Platelet count < 50,000/mm³ Once activated, the blood bank will send 6 units of PRBC, 6
units of FFP, 6 units of platelets, and 10 units of cryoprecipitate. After this, if the patient remains bleeding (the protocol has not being inactivated), 6 more units of PRBC and FFP will be prepared along with 20 units of cryoprecipitate. The latter product is given in order to elevate the fibrinogen level since the next step of the protocol is to
Recombinant Activated factor VII administer. At any point, if the patient’s hemorrhage stops, the blood
bank should be notified so that the protocol can be terminated.
If bleeding persists, the sequence is started again.
Massive Transfusion Protocol“1:1:1”

Blood Products
General considerations Keep the platelet count > 50,000. If less than
that, administer 10-12 units initiallyIf surgical intervention is necessary, maintain
Plt count > 80-100,000.Cryoprecipate may be used along with FFP
for fibrinogen levels <100, give in 6-12 unit doses
