High Risk Perinatal Care Flashcards
Diabetes mellitus
Cardiovascular disorders - adaptations in pregnancy; happens in labor
Respiratory - asthma
Integumentary
Substance abuse
Have these conditions and get pregnant
Pre-existing conditions
Pathogenesis
Classification of diabetes
Metabolic changes associated with pregnancy
Pregestational diabetes mellitus
DM
Diabetes may be caused by either or both:
Impaired insulin secretion
Inadequate insulin action in target tissues
Pancreas is not working - need insulin - drives glucose into target tissues
Pathogenesis - DM
type 1 diabetes - prior to pregnancy
type 2 diabetes - prior to pregnancy
Other specific types (caused by infection or drug-induced)
Gestational diabetes mellitus (GDM) is any degree of glucose intolerance with onset or recognition during pregnancy
Classification of diabetes - DM
Placenta - creates a resistance
2nd and 3rd trimesters: pregnancy exerts a diabetogenic effect on the maternal metabolic status - pseudo diabetic effect on woman’s body - someone already diabetic need more insulin in these trimesters; need less in end first and beginning 2nd trimester; by time viability until delivery need lot more inulin because of placenta - high levels of progesterone and estrogen making harder to control those BG
Already diabetic: Edu: diet (collab with endocrinologist or PCP on management of DM), on go up continually on insulin - BG going up
Metabolic changes associated with pregnancy - DM
Occurs in women who have pre-existing disease
After birth: Dive - no more placenta; estrogen and progesterone tanks; very conservative managing her - become hypoglycemic easily; often have insulin drips
Almost all of these patients are insulin-dependent - will be in pregnancy
Pregestational diabetes mellitus - DM
Require Preconception counseling
Maternal risks and complications
Fetal and neonatal risks
Care management
Metabolic disorders: pregestational DM
Fetal development first trimester - everything is forming; all organ sys; 13th week - have everything
When find out pregnant - halfway through first trimester - maybe 4-6 weeks
Not had well controlled BG - affect development of fetus - high BG - affects fetal development - potential congenital anomalies - imp maintain norm BG esp first trimester (risk for: heart issues, cleft palate)
Require Preconception counseling
Macrosomia
Hydramnios
Ketoacidosis
Hyperglycemia
Hypoglycemia
Maternal risks and complications
Means Big body - fetus is this
Risk to mom - if came out vaginally - lot pelvic floor damage - repetitive damage - things falling out
Macrosomia
Too much amniotic fluid - any anomalies in baby - affect amniotic fluid in baby - GI/renal issues
Hydramnios
BG has to get to go into this 200-250; DKA - happens quickly
Margin of error more narrow with prengnacy
Regular adult BG: 400-500
Ketoacidosis
Sudden and unexplained stillbirth/fetal death
Congenital malformations
Other problems that cause significant neonatal morbidity
Fetal and neonatal risks
Most concerned about
Not keep same set of prenatal appts - comes more often - in 3rd trimester - risk increases; BG harder control, baby bigger, NSTs, contraction stress test, biophys profiles, US
This can happen and not want this
Sudden and unexplained stillbirth/fetal death
Happen before found out pregnant - sugars high during development
Congenital malformations
Antepartum evaluation
Intrapartum care
Postpartum care
Care management
Deep dive: Fam hx, med hx, OB hx, same labs as reg woman
Interview
Physical examination
Laboratory tests - diabetic 2 more
Baseline renal function - diabetes screws up kidneys; pee more because GFR higher; kidney damage - lots issues - extra strain on kidneys - make sure kidneys not destroyed by diabetes
Glycosylated hemoglobin A1C - check q3months - check first come in
Check BG every time
Check urine - spilling glucose and ketones
Patient needs much more frequent monitoring
Diet and exercise - careful about this
Management more careful
Strict records of what eating; glucose log and food diary - reviewing - see if need increase insulin/change diet
Insulin therapy/Monitoring blood glucose levels
Urine testing
Determination of birth date and mode of birth - hopefully vaginal but sometimes not; tend not go to 40 weeks; happy get to 36 weeks; gestational related conditions: pre-eclampsia - DM affects CV sys - watch them and fetal development closely to see how are; want vaginal and close to term
Complications requiring hospitalization
Fetal surveillance
Antepartum evaluation
High risk
Insulin one on side and D5 or LR one on side - titrating all day - BG every hour; change based on BG
Often turn off insulin because burning off glucose as in labor
Monitor patient closely
Complications
Intrapartum care
Make sure not go hypoglycemic once delivers placenta
Insulin requirements decrease substantially
Encourage breastfeeding - burning glucose; less insulin after delivery; best for baby; requirements half as much as someone bottle feed - lactate have burn calories
Contraception
Careful giving extra estrogen - no cardiac involvement - can have estrogen in contraceptives but not if breastfeeding
DM rough on body and if pregnant - hard on body, kidneys, and heart - couple years to recover
Space pregnancies
Postpartum care
DM end 2nd almost into 3rd trimester; body work harder to move glucose - more resistance to insulin because higher levels progesterone and estrogen; all women tested 24-26 weeks - seeing rise in BG
Maternal-fetal risks
Screening for gestational diabetes mellitus
Care management: Gestational diabetes
Same as pre-gestational DM; not as huge risk congenital issues - later in pregnancy; not in formation of fetus
Biggest issue: Really big babies - macrosomia happens often - having learn manage BG; cannot manage BG well
Huge kid: Everything in baby is still 37 weeks - baby get tons fat with all sugar; babies not DM - pancreas killing it - concerned when cord clamped BG is going to tank: <40; 45 is normal in neonate - concern hypoglycemia - managed by NICU to keep BG up = hypoglycemia - brain screwed up
Maternal-fetal risks
Antepartum care
Intrapartum and postpartum care
Screening for gestational diabetes mellitus
Diet and exercise
Monitoring blood glucose levels
Insulin therapy
Fetal surveillance
1 hr oral glucose changes - easiest and most tolerated; 50 g glucose - drink whole thing - suck in 10-15 min - 1 hr after finish - draw labs; do not have to fast; <140 is standard - if pancreas working against placenta; bring something with protein after - feel like going to pass out after
3 hr glucose challenge test if 1 hr >140 = comes in another day; draw fasting - should be <95; then 100g of carb in 10 min - 1 hr later draw lab, 2 hr draw another, 3 hr draw another; feel like crud; any 2 abnormal - then gestational DM: typ about 25 weeks
Pregnancy in 3rd trimester - harder on body - baby packing weight - she will gain little bit weight - she having take BG all day; change way eats: salads, lean meats, no sugar, no sweet tea, lifestyle change in hardest part of pregnancy - huge adjustment; never had take BG - managing BG when babies getting big hard manage - baby getting bigger not usually through vagina
Oral hypoglycoemic agent
SQ insulin
Stop once deliver baby
Fetal surveillance regularly
Antepartum care
Major cardiovascular changes during pregnancy that affect women with cardiac disease are:
Lot happens to heart with heart - issues with heart lot manage
Increased incidence of miscarriage
Preterm labor and birth more prevalent
Intrauterine growth restriction is more common
Incidence of congenital heart lesions increased in children of mothers with congenital heart disease
Issue is: cannot perfuse body: preterm labor, miscarriage risk high, little baby, cannot perfuse well, worry about kidney
Antepartum assessment
Plan of care and implementation
CV disorders
Everything up except SVR
Increased intravascular volume
Decreased systemic vascular resistance - BP decreases
Cardiac output changes during labor and birth
Intravascular volume changes that occur just after childbirth
Major cardiovascular changes during pregnancy that affect women with cardiac disease are:
High likelihood miscarriage - need blood supply for embryo to implant - rich velvty luxurois - not perfusing well - not implant very well if issues with flow
Increased incidence of miscarriage
Fetus is a parasite - symbiotic relationship - body care for self - prioritizing care: preserve self before pregnancy; body having trouble perfusing self - go into labor early to preserve self
Preterm labor and birth more prevalent
Little babies
Not getting perfused
Not perfusing self well - not get as much nutrition or placenta as well as necessary
Intrauterine growth restriction is more common
Assessing baseline when first comes in
Not same routine care - pt coming in all time
Antepartum assessment
Therapy focused on minimizing stress on heart - not control adaptations to pregnancy since norm - focus on minimizing stress
Signs and symptoms of cardiac decompensation - heart giving out
Bed rest
Nutrition counseling
Cardiac medications as needed
Anticoagulant therapy
Intrapartum care - during labor
Postpartum care
Plan of care and implementation
HR lower
BP changes
Breathing issues - labored
Lots edema - extreme
SpO2 - low
Wet lungs
Color not appropriate or pink
Signs and symptoms of cardiac decompensation - heart giving out
Not fast food every night
Nutrition counseling
Risk vs benefit - some category C: consider risk for fetus or her die; measure out what more imp; some meds can change out
Cardiac medications as needed
Heparin: large-molecule drug does not cross placenta - baby not get it
Anticoagulant therapy
Care focuses on promoting cardiac function
O2 available
Encourage: Epidural - O2 consumption lower; less stress on heart; more comfy
Val salva - Increased intrathoracic pressure not good on heart
Prophylactic antibiotics
Avoid endocartitis
Intrapartum care - during labor
Monitoring for cardiac decompensation
Huge changes after placenta - extra load on heart - 1-2 L on heart still present - big changes post-partum - diligent in assessment - high acuity pt
Postpartum care
Affects 4% - 8% of all pregnancies - unpredictable; do PFTs to see baseline
Ultimate goal of asthma therapy in pregnancy is maintaining adequate oxygenation of the fetus by preventing hypoxic episodes in the mother. - prevent hypoxic episodes in mom and baby
Effective pregnancies unpredictable
Care considerations
Asthma - Other medical disorders in pregnancy: pulmonary
Some have less exacerbations
Some have more!
Effective pregnancies unpredictable
Pulse oximetry during labor and postpartum
Epidural anesthesia - encourage: in labor: breathing; hyperventilating, screaming - not want that - decrease O2 consumption; not overbreathing
Are safer choices for systemic analgesia - short-acting analgesia
At increased risk for postpartum hemorrhage
Care considerations
Due to the risk of bronchospasm Hemabate should be avoided!
cause asthma exacerbation in both
No hemabate - any other med fine; need to contract
No tobuterlin - contracting too much
At increased risk for postpartum hemorrhage - Care considerations
Integumentary disorders induced by pregnancy
Skin problems aggravated by pregnancy
Other medical disorders in pregnancy: integumentary
Melasma (chloasma)
Vascular “spiders” - varicose veins
Palmar erythema
Striae gravidarum
Pruritic urticarial papules and plaques of pregnancy (PUPPs)
Integumentary disorders induced by pregnancy
Extremely irritating; give drug to help with itching; keep up at night - claw at self - less concerning than IHC
Pruritic urticarial papules and plaques of pregnancy (PUPPs)
Acne vulgaris (in the first trimester)
Intrahepatic cholestasis (IHC)
Skin problems aggravated by pregnancy
Increase bile salts under skin - do not know why - end 2nd and into 3rd trimester - no visible evidence something wrong except claw marks from itching self - palms and soles - want rip palms and soles feet off - scratch marks - liver enzymes
Comfort measures - drugs but not help with itch
#1 concern/risk - baby dies - no idea why - routine b ile care more often and common more often
Nothing see
Close to term as possible and deliver baby
Biophys profile - induce labor or C-section; waiting game
Intrahepatic cholestasis (IHC)
Barriers to Treatment
Care management
Substance abuse in pregnancy
Not want get in trouble, jail, lose custody, find out
Red flag: not provider on record and care in variety ER; story changes every time - prenatal care from on provider to next; urine specimen to check for ketones and glucose and also check for drugs
Fear criminal prosecution
Lot not getting prentatal care
Women fear losing custody of child and criminal prosecution
Less than 10% of pregnant women receive treatment
Substance-abuse treatment programs do not address issues affecting pregnant women
Long waiting lists and lack of health insurance present further barriers to treatment
Barriers to Treatment
Substance use during pregnancy hard during prengnacy
Drug testing during pregnancy = some forthcoming = be upfront test every time test; hold accountable
Methadone maintenance program
Breastfeeding definitely contraindicated in women who continue to use amphetamines, alcohol, cocaine, heroin, or marijuana
Antipsychotics: risk vs benefit
Is an illness
Hardest to manage pain
Involve social services
Substance abusers difficult to care for particularly during intrapartum and postpartum periods
Substance abuse is an illness; women deserve to be treated with patience, kindness, consistency, and firmness
Before discharge
If infant’s well-being is questionable, case will be referred to child protective services agency
