tocolytic
is medication that is given to try to stop labor. These are considered “off-label” since they were not created for this purpose
111
What are some tocolytics (is medication that is given to try to stop labor. These are considered “off-label” since they were not created for this purpose)
Magnesium Sulfate Terbutaline Nifedipine Indomethacin
112
Magnesium Sulfate
Monitor mom’s BP, this is given in high doses so make sure mom’s room is very cool and she has a fan. She will feel like she is having real bad hot flashes. Get support person a blanket because they will probably get cold. Mom gets a 4-6 gram load dose over 20 -30 minutes, then 1-4 grams an hour maintenance dose. Baby will react with decreased variability nonreactive NST. IV fluids will be limited to 125mL/hr and mom is usually only on iy for 24-48 hours. Everything decreases with mom, watch urine output, Absent DTRs, hypotension, Magnesium & calcium level will be monitored. LOC will decrease, but mother should never be comatose. Calcium Gluconate is the reversal medication.
113
Terbutaline
– also called Brethine. given subque. 0.25 mg q 20 minutes until ctx stop up to 3 doses. When 3rd dose is given MD should be called. Your book states q 4 hours, this is no longer the best practice. Mainly watch mom. Check her Heart rate before each dose. If her heart rate is greater than 120, you will hold the dose and call the MD. The mom will tell you it feels like her heart is about to jump out of her chest because it is beating so fast. Can cause N&V, headache, hypotension, hyperglycemia, chest pain, nervousness. The baby usually does well, but may have episodes of tachycardia. Be sure to give the medication at the top of the contraction so the mom gets more than the baby due to constriction
114
Nifedipine
may also see Procardia or Aldalet – Usually given orally – 10-20 mg q 3-6 hours. Once contractions have slowed the mom will get extended release 30-60mg PO 8-12 hours. Be sure to take mom’s Bp before giving because it can cause hypotension, Headache, flushing, dizziness and nausea
115
Indomethacin
May give 50 mg PO then 25-50 mg PO q6 hours for 48 hours. Before 32 weeks may be given as a rectal suppository. Mom may complain or heartburn or nausea. Watch for bleeding (NSAID). The fetus may start to have decreased urine output, and the ductus arteiosis may constrict decreasing fetal circulation
116
mom’s membranes have spontaneously ruptured before labor has started at any gestational age is called?
PROM – Prelabor Rupture of Membranes
117
Mom’s membranes have spontaneously ruptured before 37 weeks gestation is called?
PPROM – Preterm Premature Rupture of Membranes
118
Placenta abruption
occurs when the placenta detaches from the inner wall of the womb before delivery. The condition can deprive the baby of oxygen and nutrients.
119
Placenta Previa
occurs when the babys placenta partially or totally covers the mothers cervix
120
Maternal Risks and Complications with Gestational diabetes
Worsening of pre-existing disease  vascular problems  retinopathy Hypoglycemia 1st half of pregnancy Hyperglycemia  Ketoacidosis 2-3rd trimesters (high blood values) Preeclampsia and Eclampsia Polyhydramnios in 10-20% of diabetic Dystocia (shoulder)
121
Effects on baby with mom with diabetes
-Macrosomia r/t excess glucose from Mom (poor glucose control… BIG baby greater than 4000 grams) -Large for gestational age (LGA) -IUGR r/t maternal vascular involvement -Delayed lung maturity  RDS -Hypoglycemia after birth -Congenital anomalies Neural tube defects Skeletal defects (Sacral agenesis)
122
Management of DM During Pregnancy
Monitor Glucose Diet Exercise Insulin (may or may not if diet and exercise can make it come back down.)
123
HYPEREMESIS
- Severe vomiting of pregnancy that causes weight loss of at least 5% of prepregnancy weight. - Accompanied by dehydration, electrolyte imbalance, nutritional deficiencies and ketonuria. - Usually begins at 4 weeks and can last up until 20 weeks of pregnancy. - Could be caused by increasing levels of estrogen, progesterone & human chorionic gonatrophins (hCG) .
124
Fetal risk from hyperemesis
-IUGR -Abnormal development (anomalies) -Death from lack of nutrition, hypoxia or maternal ketoacidosis Ketoacidosis = accumulation o f ketones in the blood from hyperglycemia that leads to metabolic acidosis. Be very careful with Terbutaline and corticosteroids – these can contribute to DKA
125
Symptoms of Hypoglycemia
``` Nervousness HA Shaking/irritable Hunger Blurred vision Diaphoresis ```
126
HELLP Syndrome
A variant of severe preeclampsia. - Hemolysis - Elevated liver enzymes (liver is not getting rid of toxins it needs to get rid of) - Low platelets (not making it to where they can coagulant) -Lab work will tell you if they have HELLP Syndrome Nursing responsibilities: Assess and observe for signs of bleeding. Pt can have bad epigastric pain, if pt tells you it feels like bad ingestation that means liver involvment, see if she looks yellow or jaundice. Can mean placenta abruption.
127
Glucose screening is done when?
at 24-28 weeks gestation. Higher risk patients will be done earlier. Routine: -fasting glucose will be taken -Pt will drink the 50g of oral glucose cola -Pt will wait 1 hour then they will check glucose -If glucose is > 130-140 mg/dL it is POSITIVE (gestational diabetes)--> requires follow up appt. - If have to come back they will take a 3 hr glucose tolerance test. They can eat whatever they want. They will be npo after midnight. Will drink 100 g glucola. Blood will be drawn at 1,2, and 3 hours. - A positive test is when 2 or more values are equal or exceed
128
Euglycemia (normal glucose)
65-95 before meal | 130-140 1 hour after meal
129
Treatment for hypoglycemic mom
Tell them to eat like half of a sandwhich or give them whole milk to drink. If its really low give them some SL glucose paste
130
Amniocentesis
Ultrasound guided needle through abdomen into uterine cavity to obtain amniotic fluid for testing. Done after 14 weeks gestation when uterus rises above the symphysis pubis and fluid amounts are adequate to get sample. Fluid shows: Lecithin/syhingomyelin (L/S ratio) or shake test Checks for Fetal Maturity Alpha-fetoprotein Used as screening tool for Neural Tube Defects Desquamated fetal cells Allows for genetic testing
131
Timing of Amniocentesis
Early pregnancy – to detect chromosomal abnormalities Late pregnancy – most often to determine fetal lung maturity with L/S ratio to detect the amount of surfactant production in fetal lungs. Ratio of 2:1 indicates fetal lung maturity Surfactant is a substance that reduces the surface tension of pulmonary fluids to allow gas exchange in the alveoli
132
Alpha- fetoprotein
Is used to test for down syndrome and for neural defects
133
Fetal heartbeat is heard by ____ weeks
10-12
134

end of 28 weeks
136
L/S ratio 2:1 at _____ weeks

137
Contraction Stress Test (CST) or Oxytocin Contraction Test (OCT)
Findings are Negative, Positive or Equivocal No Late Decelerations = Negative CST/OCT Late Decelerations = Positive CST/OCT *CST - you want a Negative test = Baby not stressing because of ctx
138

141
Triangular helmet shaped cells found in blood, usually indicative of disorders of small blood vessels
Burr cell
142
Menstrual cycle
Hypothalamus secretes GnRH GnRH stimulates Pituitary to secrete FSH (follicle stimulation hormone) FSH stimulates growth of a follicle(s) Follicles contain an egg in them along with cells that secrete estrogen As the follicle starts to matures, the Hypothalamus released even more GnRH which then makes the Pituitary secrete a large spike of LH at once(luteinizing hormone) LH essentially bursts open the follicle and releases the egg into the fallopian tube into the uterus The bursted follicle turns in the corpus luteum Corpus luteum secretes progesterone If there’s no fertilization of the egg, the corpus luteum withers and progesterone & estrogen decline This decline leads to shedding of the uterus & the cycle repeats If there is fertilization, no menstruation occurs. Corpus luteum continues to secrete progesterone & estrogen for the first few months.
143
Placenta Previa
the placenta is implanted in the lower uterine segment such that it completely or partially covers the cervix or is close enough to the cervix to cause bleeding when the cervix dialtes or the lower uterine segment effaces
144
Placenta Abruption
the detachment of part or all of a normally implanted placenta from the uterus
145
