Causes of PPH
100
At what blood loss percentage will signs of hemorrhage begin to be apparent?
What is >15%?
100

This technique is used to bilaterally ligate the uterine arteries, thus occluding 90% of the blood flow to the uterus.

What is O'Leary technique?

100

Caused by uterine atony, retained placenta (especially accreta), coagulation defects, and uterine inversion.

What is primary hemorrhage (within 24 hours)?

100

It can cause fever (transient) as a side effect.

What is Cytotec (misoprostol)?

100

This causes 70-80% of PPH.

What is uterine atony?

200

This blood component increases 25% in pregnancy.

What is red cell mass?

200

Typically employed after other conservative measures have failed, this PPH intervention works by applying temporary, uniform pressure to the lower uterine segment while allowing for continuous monitoring of blood loss.

What is a Bakri balloon?

200

A consequence of PPH, with lactation failure as the first symptom.

What is Sheehan Syndrome?

200

Given as 10u IM

What is oxytocin (pitocin)?

200
Detection of an echogenic mass within the uterus is highly suspicious. 

What is retained placental tissue?

300

Blood component that increases 40% in pregnancy

What is plasma volume?

300

The radiologically-guided technique performed in hemodynamically stable patients with persistent slow bleeding who have failed less invasive therapy.

What is arterial embolization? 

300

Excessive bleeding that occurs more than 24 hours after delivery and up to 12 weeks postpartum occurs in approximately 1% of pregnancies.

What is secondary or delayed postpartum hemorrhage?

300

What is the dosage of PPH medication with HTN as a contraindication?

What is 0.2 mg IM for methergine (methylergonovine)? May be given Q2-4 hours.

300

On bimanual examination, you find a firm mass below or near the cervix, coupled with the absence of identification of the uterine corpus on abdominal examination.

What is a uterine inversion?

400
1 unit of packed RBC will usually increase Hgb by how much?
What is 1 g/dL?
400

During a laparotomy for PPH, this technique is used to apply uniform uterine compression using absorbable sutures that encircle the body of the uterus.

What is B-Lynch technique?

400

A synthetic analog of the amino acid lysine and inhibits the formation of plasmin by attaching to glycine on the plasminogen.

What is TXA?

400

This medication is a prostaglandin F2-alpha. 

What is Hemabate?

400

Consider in cases of HELLP, abruption, prolonged IUFD, sepsis, or amniotic fluid embolism.

What is DIC or coagulopathy?

500
What are the two types of blood components that will increase fibrinogen by 10 mg/dL, and how do they differ?
What is cryo and FFP? Both with fibrinogen and Factor VIII. FFP (250 cc) also with antithrombin III and factor V. Cryo (40 cc) also with factor XIII and von Willebrand factor.
500

A technique that can be performed either unilaterally or bilaterally at the time of ex-lap for PPH is used to decrease pulse pressure to the uterus further after other conservative measures have failed.

What is hypogastric artery ligation?

500

Blood transfusion reaction secondary to donor anti-leukocytes antibodies against recipient endothelial cells. 

What is transfusion-related acute lung injury (TRALI)?
500

What is the dose of TXA? How soon can a 2nd dose be given? 

What is 1g? and what is 30 minutes?

500

Deterioration of maternal vital signs without obvious bleeding should alert the obstetric team about this possible condition. 

What is intraperitoneal or retroperitoneal bleeding?
