Severe preeclampsia is defined as ________
160/110mmHg
>2gm/24 hours
Basic Pathology of preeclampsia
Vasospasm
Passage of meconium is a sign of _______ due to stimulation of posterior pitiitary gland which produce ADH thereby increases GI motility

Calcium gluconate
When is the BP of postpartum mother returns back to normal?
< 12 weeks
What is chronic hypertension with superimposed severe preeclampsia?
New onset proteinuria >= 300mg/24 hours in hypertensive women but no proteinuria before 20 weeks’ AOG
What is chronic hypertension?
BP equals to or >140/90 mmHg before pregnancy or diagnosed before 20 weeks gestafion nir attributable to GTD
Hypertension first diagnosed after 20 weeks’ AOG and persistent after 12 weeks postpartum
MAP value in the 2nd trimester
> 90 mmHg
MAP value in the 3rd trimester
> 105 mmHg
What are the screening maneuvers of pre-eclampsia?
MAP
Supine pressure test or roll-over test
Conbination of MAP and roll-over test
What is the finding at 12-14 weeks AOG that is considered to be a useful tool in predicting the developement of hypertensive disorders in high risk prengnancy?
Bilateral notching
Effective test in predicting PIH at 24 weeks AOG
Doppler velocimetry of the uterine and uteroplacental arteries
Glycoprotein derived principally from the liver and endothelialbcells and its release into plasma is a marker of vascular disruption and endothelial cell activation

2nd most common cause of maternal death
Eclampsia
Stage of preeclampsia characterized by faulty vascular remodeling of uterine artery cauding placental hypoxia
Stage 1 - preclinical
Stage of preeclampsia characterized by release of placental factors into the ciculationb-> SIR and endothelial activation
Stage 2 - late stage
Hallmark of eclampsia
Hemoconcentration
Renal biopsy finding of eclamptic pregnant
Glomerular capillafy endotheliosis
Headache and scotoma (as a manifestation of eclampsia) are thought to arise from cerebrovascular hyperperfusion that has predilection at what part of the brain?
Occipital lobe
Proposed MOA of MgSO4 in the prevention of eclampsia
- Reduced presynaptic release of glutamate
- Blockade of NMDA
- Potentiation of adenosine action
- Improved mitochondrial calcium buffering
- Blockade of clacium entry
Maneuver stating that the fetal head should be maintained in a flexed position during delivery to allow passage of the smallesr diameter of the head
Mauriceau Smellie Veit maneuver
Maneuver employed when the arm of the baby cannot be deliver during breevih delivery. Fetal body is turned 90 degreesbinto then transverse, reached over the baby’s shoulder and slipsnthenfinger down into brachial plexus sweeping the arm down in front of the baby’s body
Loveset’s maneuver
Forceps that may br used if the mentum is anterior
Kielland forcep
Prophylactic CS is warranted if with the following EFW findings
EFW >4,500g (with maternal DM)
EFW >5,000g (without DM)
What is the dystocia drill?
Call for help Episiotomy Suprapubic pressure McRobert maneuver Delivery of posterior arm Woods screw maneuver Rubin maneuver Zavanelli maneuver Cleidotomy Symphysiotomy
Maneuver that involves progressively rotates the posterior shoulder 180 degrees, the impacted anterior shoulder could be released
Woods screw maneuver
Maneuver that involves the fetal shoulders rocked from side to side by applying force to the maternal abdomen
Rubin maneuver
Maneuver that most often abducts both shoulders which in turn produces a smaller shoulder to shoulder diameter which permits displacement of the anterior shoulder behind the symphysis
Rubin maneuver
Maneuver that replaces or flexes the fetal head back into the vagina and then CS is performed
Zavanelli maneuver
Deliberate fracture of the anterior clavicle to free the shoulder impaction
Cleidotomy
Intervening symphyseal cartilage and much of its ligamentous support is cut to widen the symphysis
Symphysiotomy
Maneuver needed with a frank breech to facilitate delivery of the legs but only after the fetal umbilicus has been reached. Pressure is exerted in the popliteal space of the knee. Flexion of the knee follows and the lower leg is swept medially and out of the vagina
Pinard maneuver
Elective CS for vasa previa is done at what AOG?
35-37 weeks AOG
Mode of delivery for pregnants who develop primary genital herpes within 6 weeks of delivery
CS
AOG wherein elective CS with HBV profile are as follows: HbeAg positive, HBV DNA copies >1,000,000 and does not received oral antiretroviral therapy
