Difficult/Extra cards Flashcards
Increases A1 acid glycoprotein:
surgical stress, MI, chronic pain, RA, advanced age
What activates Adenylate cyclase?
Inhibits?
What does activating/inhibiting do?
Activate: B(1,2),V2, H2
Inhibits: M(2,4), A2
Activating increases cAMP, inhibiting decreases
(cAMP decreases Calcium -> bronchodilation)
What activates Phospholipase C? What does that do?
Activates: H1, A1, V1, M135 increases IP3, DAG, Calcium (Increase IP3 -> increase Calcium -> bronchoconstriction)
where is the site of action for immobility for inhaled anesthetics
ventral horn
in which 3 regions of the brain do halogenated anesthetics produce unconsciousness
cerebral cortex
thalamus
reticular activating system
in which 2 regions of the brain do halogenated anesthetics produce amnesia
AH!
amygdala
hippocampus
Tetralogy of fallot is characterized by these 4 things: What is best induction agent?
VAPR
- VSD
- Aorta that overrides RV and LV
- Pulmonic stenosis
- RV hypertrophy
Ketamine best induction agent
Minimize right to left shunt by:
Increase Preload and SVR
Decrease PVR
Maintain HR + Contractility
Causes of hypocalcemia
hyperventilation
albumin
citrated blood products
what is the most common cause of postpartum hemorrhage?
Uterine Atony Caused By:
multiparty, multiple gestations, polyhydramnios, prolonged oxytocin infusion prior to surgery
what are the risk factors for placental abruption
PIH, preeclampsia, chronic hypertension, cocaine use, smoking, excessive etoh use
what conditions increase the risk of abnormal placental implantation?
placenta previa and previous c/s
DIC in pregnancy is associated with?

- Intrauterine fetal demise
Neonate directly after birth: Normal spo2 is ___. It should rise to ___ after 10 minutes. Supplemental o2?
60%
90%
f assisting is needed, use room air as 100% fio2 can accompany an inflammatory response
Neonate rescussitation: Emergency meds can be given 3 routes:
- Umbilical vein
- Endotracheal
- Intraosseous
only after 90 seconds of CPR. Start CPR with HR <60
