Obstetric Patho 2 Flashcards
What is colostrum?
The initial breast milk produced during late pregnancy
Where is pre-eclampsia thought to originate from?
From Defects or detrimental changes within the placenta
The transition from pre-eclampsia and eclampsia is marked by the onset of….
Seizures
Postpartum preeclampsia can manifest up to ___ weeks postpartum
6 weeks
What serious complications can high BP in preeclampsia lead to?
- hemorrhagic stroke
- retinal detachment
How does high blood pressure in pre- eclampsia contribute to cerebral edema or potential hemorrhage?
The high BP increases hydrostatic pressures in the cerebral vessels
Preeclampsia can manifest as RUQ pain, this tells us that the liver is being affected. What liver complications can be due to preeclampsia?
- hepatic rupture
- subcapsular hemmorrhage
- liver failure
- hepatomegaly
What is Disseminated Intravascular Coagulation (DIC)
A condition that is characterized by systemic coagulation followed by sever bleeding due to consumption of clotting factors
What is HELLP syndrome?
The sever progression of Preeclampsia involving
-hemolysis
- elevated liver enzymes
- and low platelet count
How does preeclampsia lead to systemic edema?
Proteinuria decreases intravascular proteins such as albumin, which reduces oncotic pressure , resulting in edema
What is placenta previa?
The placenta implanting in the lower part of the uterus, covering the cervix partially or fully
Why is hemolysis apart of the HELLP syndrome?
This is because the high blood pressure damages the red blood cells hence HEMO-LYSIS
When does bleeding typically occur with a placenta previa individual
Third trimester
What fetal risks do placenta previa potentially cause?
- preterm birth
- respiratory distress syndrome
- meconium aspiration
What are the causes/mechanisms for placental abruption
- trauma
- prolonged pressure on VC
- preeclampsia
- abnormal uterine anatomy
- smoking
- short umbilical cord
