Pregestational Conditions Flashcards
- Valve Damage
- Caused by recurrent episodes of Acute Rheumatic Fever (ARF)
– Heart has become inflamed
– Heart valves remain stretched and/or scarred normal blood flow is interrupted
Rheumatic Heart Disease
___ is damage to the heart that remains after an Acute Rheumatic Fever episode has resolved
Rheumatic Heart Disease
- Illness caused by “group A streptococcus”
- Causes acute, generalized inflammatory response
Acute Rheumatic Fever (ARF)
Recurrence of ARF = _____?
Cardiac Valve Damage
Acute Rheumatic Fever targets which specific parts:
- Heart
- Joints
- Brain
- Skin
(Leaves no damage on 2-4)
- Has persisting HEART damage (RHD)
Dyspnea (Normally During Pregnancy)
- Increase mother’s blood volume (30-50%)
– Half of this increase occurs during the 8th week of pregnancy - There is functional (innocent) or Transient heart murmurs
(transient = temporary) - Heart palpitations on sudden exertion
- Cardiac output falls (vital organs, placenta are no longer perfused adequately)
- Mother and Baby’s O2 and Nutritional req. are not met
Most dangerous time for mother’s with Dyspnea?
28-32 weeks
Dyspnea (Management)
-
Team approach
1. Internist-Cardiologist
2. Obstetrician
3. Nurse - Should visit Obstetrician before planning to get pregnant (baseline status)
–Advise to cease work
DIAGNOSTICS
- Echocardiography to assess valvular function
-
Successful completion of pregnancy
– Depends upon the type extent of disease -
Woman with artificial but well functioning heart valves
– Consistent prenatal and postpartum care
Preventing recurrences of ARF
Prophylactic treatment with penicillin
- An Endocrine Disorder in which the pancreas cannot produce adequate insulin to regulate body glucose levels
Diabetes Mellitus
Diabetes Mellitus affects ___% of all pregnancies
- 3-5% of pregnancies
Most frequently seen medical condition in pregnancy
- Diabetes Mellitus
Diabetes Mellitus (Classification)
- Type 1
- Insulin - dependent DM - Type 2
- Non-insulin - dependent DM
- Abnormal glucose metabolism that arises during pregnancy
- Symptoms fade again at the completion of pregnancy
Gestational Diabetes Mellitus
Gestational Diabetes Mellitus (Risk Factors)
- Obesity
- Age < 25 years
- History of Large Babies (10lbs or more)
- History of unexplained fetal or perinatal loss; congenital anomalies in previous pregnancies; polycystic ovary syndrome; diabetes
- Member of a population with a high risk for diabetes
- Native American
- Hispanic
- Asian
- A state between normal and diabetes
- Body is no longer using and/or secreting insulin properly
Impaired Glucose Homeostasis
Gestational Diabetes Mellitus (Normally)
- Develops insulin resistance (insulin seems to be ineffective during pregnancy)
- Placental insulinase may cause increased breakdown of insulin
– Helpful because it prevents blood glucose from falling to dangerous limits
– Insulin dosage is increased beginning about 24 weeks to prevent hyperglycemia
Insulin is ineffective during pregnancy due to?
- Presence of Human Placental Lactogen
- High levels of:
1. Cortisol
2. Estrogen
3. Progesterone
4. Catecholamine
Gestational Diabetes Mellitus (Signs and Symptoms)
- Hypoglycemia
- Continued use of glucose by the fetus
- Opt to occur overnight
- Ketoacidosis (during 2nd and 3rd Trimester) - Polyuria
- Excessive urination - Polydipsia
- Excessive thirst - Polyphagia
- Excessive or extreme hunger - Fatigue
- Blurred Vision
- Weight loss
Gestational Diabetes Mellitus (Primary Problem)
- Controlling the balance between insulin and blood glucose levels
– Prevent hyper and hypoglycemia
Gestational Diabetes Mellitus (Management)
Reproductive Planning
- Oral Contraceptives are NOT allowed
– Progesterone interferes with insulin activity (increases blood glucose levels)
– Estrogen has the potential for increasing cholesterol and lipid levels and blood coagulation - IUD
– Associated with Pelvic Inflammatory Disease (PID) (women with DM have difficulty fighting infections) - Subcutaneous implanted or IM injections of progestin are good choices
Gestational Diabetes Mellitus (Maternal and Fetal Risk)
Maternal Risk:
1. Maternal Pelvic Inflammatory Disease (PID)
2. Infection (Monilial Infection)
3. Spontaneous Miscarriage
Fetal Risk:
1. Growth Restriction
2. Asphyxia
3. Stillbirth
4. Macrosomic - Large for gestational age
- Possible problem with Cephalopelvic Disproportion (CPD)
- Increased risk for shoulder dystocia
5. Congenital Anomaly
- Caudal regression syndrome
– Failure of the lower extremities to develop
Gestational Diabetes Mellitus (Management)
- Keep woman from hyperglycemia
– Less chance for congenital anomaly
Substance Abuse results in?
- Miscarriage
- Low Birth Weight (LBW)
- Premature Labor
- Placenta abruptio
- Fetal Death
- Maternal Death
