examples of high risk conditions for pregnancy
young age, poor nutrition, diabetes, HTN, drug use, geriatric pregnancy, multiple gestation, stress
when does risk assessment of pregnancy begin
at the first prenatal visit and at each visit
maternal morbidity and mortality effect what groups
patients who are high risk, black and asian women, increased with age
pad saturation that is considered hemorrhage
1 pad full in 1 hr
late bleeding (usually after 20 week of gestation) can indicate
placenta previa as well as placenta abruption
(NO cervical exams, speculums etc until confirmation that there is not placenta previa
abortion
-loss of pregnancy before 20wks
-spontaneous miscarriage by natural causes
- diagnostic tests include TVUS and also HCG levels decrease or level out
- management can include D&C (they dilate the cervix to clean the uterus) and misoprostol
cervical insufficiency
-can't carry baby sufficiently
- painless cervical dilation in second trimester
-treated by cerlage (suture to close cervix), bedrest, and no intercourse
ectopic pregnancy
-implantation outside uterus usually in fallopian tube
- rupture is medical emergency, can lead to hemorrhage. salpingectomy is performed to remove tube
- risks: previous ectopic pregnancy, history PID, genital infections or endometriosis, infertility, smoking, vaginal douching
- manifests as unilateral pain, vaginal spotting or light bleeding after missed menstrual cycle
-treatment is other contraceptives for least 3 months to heal
-methotrexate can be used IM in unruptured pregnancy to stop the cell growth. must be administered by a certified nurse
placenta previa
abnormally low implantation of the placenta on the uterine wall completely or partially covering the cervix
- painless bright red bleeding, late decels in FHR
- NO cervix checks
- risks: previous placenta previa or c-section, multiple gestation, increasing parity(births), increasing maternal age, infertility treatment, smoking or cocaine use
- monitor maternal-fetal status= no vaginal exams with bleeding, non stress tests emergency = section
- requires hospitalization or prolonged bedrest, adequate hydration (1 gallon a day) and no intercourse
placenta previa types

placenta abruption
-firm board like abdomen, port wine stain
- placental detachment after 20 wks gestation
- is hemorrhage into maternal blood vessels between placenta and uterus causing hematoma causing the separation which causes fetal hypoxia and possible fetal death
- risks include HTN, smoking maternal cocaine use, multigravida (multiple pregnancies), abdominal trauma, history of previous separation, autoimmune
- management with emergency is c section, IVFs to correct blood loss with blood administration, isotonic using 18g
- assess for fetal anoxia, minimal or absent variability and late decels
- type and cross match
- with a car accident you’d monitor for 4 hrs
hyperemesis gravidarum
- severe and persistent uncontrolled vomiting begins by 6 weeks gestation
- associated with acute starvation (acidosis) and dehydration and can require hospitalization
- lose 5% of body weight
- HCG levels are higher, high estrogen levels, relaxed LES, genetics
-ptyalism (excessive salivation)
- increased LFTs
- hypokalemka and hyponatremia
- elevated ketones
- renal dysfunction
- treat with dietary changes, ginger (250mg 4x a day), fluid replacement, poss banana bags, enteral feedings, NPO
what meds can you might expect with hyperemesis gravidarum
antiemetics which include
- reglan (pump) but if given too fast can cause seizures
- vitamin b6 (pyridoxine) plus doxylamine (diclegis)
-promethazine (phenergan) has sedative effects. dilute 10 ml NS

- can do crackers before getting up in the morning, also brat diet (bananas, rice, applesauce, toast)
chronic HTN
exceeds 140/90 (and/or) before pregnancy or before 20 wks)
- monitor for worsening HTN or preeclampsia and or HELLP syndrome
- treat with antihypertensives but may not be required. does NOT reduce likelihood of developing preeclampsia
- with BP increased all the time the placenta grows old
- increases likelihood of intrauterine growth restriction which means placenta stops giving baby nutrients
gestational HTN
higher than 140/90 in a previous normotensive patient w/o proteinuria after 20 wks gestation
- at least two occasions of 140 and/or 90 atleast 4-6 hrs apart
preeclampsia
- after 20 weeks
- new onset of HTN
- proteinuria (>300mg in 24 urine, 1+ on dipstick (2 random collections no evidence of infection)
- maternal organ dysfunction targets cardio, hepatic, renal, CNS system
-risks: primigravida, younger than 20 older than 35, sperm can also release enzyme and can be allergic then body uses with BP developing pre eclampsia, autoimmune disorders
preeclampsia characterized by
-elevated bp readings on 2 occasions
- proteinuria, oliguria symbolizing decreased renal perfusion
- headache and visual disturbances showing poor cerebral perfusion
- edema
-epigastric pain (ominous sign) burning, gnawing under right breast that does not go away
- increased liver enzymes, platelet levels, increased LDH and uric acid, increased BUN and creatinine
meds of preeclampsia
- aspirin 81mg given from 12 weeks for prevention of clots
- magnesium sulfate (muscle relaxant, decreases CNS excitability and vasodilates, given IV. mag level in OB is 4-7. monitor heart, keep oral airway in room, lung assessment, strict I/O,
-hydralazine (lowes BP, is a smooth muscle relaxant. IV push every 20-40 minutes
- labetalol decreases BP without decreasing heart rate and CO. IV push 20mg over 20 min
- nifedipine is a calcium channel blocker. decreases BP preterm labor. PO 10 mg every 20 minute up to 3 doses
- monitor for clonus, monitor I/O, frequent lung assessment, vital signs and FHR
magnesium toxicity
decreased RR
decreased DTR
sluggish
* stop drop
* calcium gluconate antidote
* 3 mL over 10 min is how mag is given

S- significant lab changes n LFTs and platelets
M- multi organ involvement
S- symptoms after 20 wks gestation
Eclampsia
hallmark neurologic complication of preeclampsia
- tonic clonic seizure activity
- medical emergency

-if greater than 4500g, c section is recommended.
-complication of diabetes in mom
intrauterine growth restriction
placenta is "growing old" and baby doesn't grow as efficiently
-complication of gestational diabetes
newborn hypoglycemia
can be a complication of gestational diabetes. newborn blood sugar automatically at birth, should be greater than 30 mg/dl

-stop contractions
-closes a patent ductus arteriosus in premature infants by inhibiting prostaglandin synthesis
nifedipine
relaxes uterus, used to suppress premature uterine contractions
nonstress test (NST)
used to assess fetal wellbeing
is completed in 20 minutes
documented as reactive or nonreactive
if patient is greater than 32 weeks, needs to be 15×15 (increases 15 beats for 15 seconds) to be reactive
if patient is less than 32 weeks, needs to be 10×10( increases 10 beats for 10 seconds) to be reactive
* if nonreactive, move mom etc. if it doesn't work, call provider and recommend a biophysical profile (BPP)
biophysical profile
ultrasound assessment of fetal well being that goes along with the NST
-30 mins with 10 points total.
-8-10 points is normal. if 6 or below it could indicate fetal compromise
*body movements: 3 or more limb or trunk movements
*fetal tone: one or more of full extension and flexion of limb or trunk
*fetal breathing: one or more breathing movements of more than 30 secs
*amniotic fluid volume: one or more pockets measuring more than 2 cm
*NST: normal 2 points, abnormal 0 points
amniocentesis
aspiration of fluid for analysis, contains fetal cells to detect and confirm abnormalities and defects
-increased alpha-fetoprotein indicates neural tube defects
-decreased alpha-fetoprotein indicates trisomy 21
-can also assess fetal lung maturity
*risks include puncture site bleeding, ROM, vaginal bleeding and contractions
amniotic fluid index
normal is 8-24.
-if less than 5, oligohydramnios can indicate renal problem
-if greater than 24, polyhydramnios can indicate neural tube defects
treatment of oligohydramnios

complications of induction
tachysystole with fetal distress and bradycardia
vaginal bleeding, lascerations, umbilical cord prolapse, perineal laceration, pp hemorrhage
augmentation
