DM Obesity, Multile Gestation, Abnormal Presentation Flashcards
Abnormal presentations
Transverse lie, face, brow, compound
Breech (frank, incomplete, complete)
Describe normal presentation of fetus
Cephalic presentation Head enters birth canal first Face backward towards mother spine Arms crossed Chin and neck bent forward down toward chest
Most common complication with breech and its treatment?
Umbilical cord prolapse
Stat c section
Fetal entrapment happens more often with that babies
Pre term <32 weeks bc of their small heads
Pharmacologic treatment for vaginal breech
Goal is complete relaxation
NTG 1-2 sublingual sprays 400-800 mcg
IV 50-500mcg
External cephalic version is done when
Ideally at term and at the hospital due to CS capability
prior to labor
What pharmacologic meds can be used for skeletal and cervical/uterine smooth muscle relaxation
Skeletal muscle relaxation 3% 2-Chloro Smooth muscle relaxation NTG 160-600 mcg for fetal head entrapment 50-100mcg for retained placenta GA:2-3 MAC
Maternal complications with multiple gestation
Antepartum/postpartum hemorrhage DIC Operative delivery - forceps CS Obstetric Trauma Preterm premature ROM Preterm labor Prolonged labor Preeclampsia/eclampsia Placental abruption Uterine atony
Fetal complications in multiple gestation
Congenital anomalies Cord enlargement IUGR Malpresentation Preterm delivery Polyhydramnios Twin to twin transfusion Umbilical cord prolapse
Fetal consequence for twin to twin transfusion
Circulatory overload with HF
Occlusive thrombosis Polycythemia
hyperbilirubinemia and kernicterus
Maternal physiologic changes for multiple gestation
Greater decrease in FRC Increased O2 consumption Blood volume 500ml greater with twins Increased CO2 Aortocaval compression CNS spread of spinal, reduce dose (increased uterine size, more progesterone)
Route of delivery for triplets or higher
CS
Fetal presentation types for twins
Can be either vertex or non vertex
Steps for anesthetic management of multiple gestation
Large bore IV, T&S Epidural or CSE Twin B may need manipulation LUD Fluids/vasopressors GA Uterine relaxation, NTG
What anesthetic management is preferred with multiple gestation
Regional - epidural over spinal
GA causes a greater decrease in FRC and increased O2 consumption
Class of DM during pregnancy where gestational DM is diet controlled
A1
Class where gestational diabetes requiring insulin
A2
What class has pre-existing DM with onset >20 y/o and duration <10 years without complications
B
What class has pre-existing diabetes with onset between ages 10 and 19 or duration of ages 10 to 19 without complications
C
What class of diabetes has pre-existing diabetes with onset <10 or duration >20 years, without complications
D
What class of diabetes has pre-existing diabetes complicated by neuropathy
F
What class of diabetes has pre-existing diabetes complicated by proliferative retinopathy
R
