Causes: uterine atony - marked hypotonia of uterus - leading cause of PPH
Associated with: high parity, hydramnios, macrosomic fetus, multifetal gestation
Uterine atony - greatest risk within first 4 hours of birth - uterus contracts to prevent contracting - if it doesn't contract - uterine atony (hypotonia - lack of tone)
First sign is profuse bleeding, palpate uterus (boggy)
You have 30 mins to deliver placenta, after 30 mins - some kind of intervention (manual removal - pull placenta off of uterus) can cause hemorrhage, infection, and pieces left behind
1. Early recognition and treatment of PPH are critical
2. Initial intervention is firm massage of the uterine fundus
3. Expression of any clots in the uterus
4. Elimination of bladder distention
5. Continuous IV infusion of 10-40 units of oxytocin added to 1000mL of IV fluid
6. Additional uterotonic meds
7. Surgical management: D&C (surgical scrape of placenta off uterus)
8. One hand remains cupped against the uterus at the level of symphysis pubis to support the uterus and the other hand cupped to massage and gently compress the fundus toward the lower uterine segment
Results from formation of blood clot or clots inside a blood vessel, caused by inflammation or partial obstruction of vessel
Superficial venous thrombosis - involvement of the superficial saphenous system
DVT - occurs most often in the lower extremities; involvement varies but can extend from the foot to the iliofemoral region
PE - complication of DVT occurring when part of a blood clot dislodges and is carried to the pulmonary artery, where it occludes the vessel and obstructs blood flow to the lungs
Occurs most frequently with ABO incompatibility - most common, and Rh (D) Incompatibility - second most common
Four major blood groups - A, B, AB, O
Rh factor: person who is Rh negative means he/she does not have the Rh(D) antigen
Rh Incompatibility (Isoimmunization): Rh positive offspring of an Rh negative mother are at risk, mother forms antibodies that then destroy fetal RBCs (hemolysis), results can be mild (fetal jaundice) or severe (erythroblastosis fetalis, hydrops fetalis- most dangerous)
ABO Incompatibility: Fetal blood types is A, B, or AB, and the maternal type is O, natural occurring anti A and anti B antibodies are transferred across the placenta to the fetus
Care Management of Hemolytic Disease of the Newborn
1. Determine the blood type and Rh factor of every pregnant woman
2. CDC urges all women of childbearing age consume 400mcg of folic acid each day, in addition to consuming food with folate from a varied diet, to help prevent major birth defects of the baby's brain - neural tube defects
Three overlapping phases: Acute distress, Intense grief - guilt, anger, resentment, bitterness, or irritability, Reorganization - better able to function at home and work, experiences a return of self esteem and confidence, can cope with new challenges, and has placed the loss in perspective
Biophysical - genetic disorders, nutritional and general health status, and medical or obstetric-related illnesses
Psychosocial - maternal behaviors and adverse lifestyles, emotional distress and disturbed interpersonal relationships, inadequate social support, unsafe cultural practices
Sociodemographic - lack of prenatal care, low income, marital status, and ethnicity
Environmental - hazards in workplace and woman's general environment, chemicals, anesthetic gases, and radiation
1. Daily Fetal Movement count (DFMC) - used to monitor fetus in pregnancies complicated by conditions that may affect oxygenation, a count of fewer than 3 kicks in 1 hour warrants further evaluation by a nonstress test (NST)
3. Chorionic Villus Sampling (CVS) - catheter inserted through vagina into uterus to sample villi of placenta, technique for genetic studies, earlier diagnosis, rapid results, performed at 10 weeks gestation
4. Percutaneous umbilical blood sampling (PUBS) - direct access to the fetal circulation during the second and third trimesters, most widely used method for fetal blood sampling and transfusion, insertion of needle directly into fetal umbilical vessel under ultrasound guidance
Maternal serum alpha-fetoprotein (MSAFP) - screening tool for neural tube defects (NTDs) in pregnancy, detects 80% to 85% of all open NTDs and open abdominal wall defects early in pregnancy, screening recommended for all pregnant women between 14-22 weeks gestation
Triple and quad screening to detect autosomal trisomy's, multiple marker screens
Coombs Test - screening tool for Rh incompatibility, detects other antibodies that may place fetus at risk for incompatibility with maternal antigens
Cell Free DNA screening in maternal blood - noninvasive prenatal genetic testing, provides definitive diagnosis noninvasively for fetal Rh status, fetal gender, and certain paternally transmitted single gene disorders, Trisomy 21 - performed as early as 10 weeks of gestation, results are usually available in about 10 business days
Pregnancy specific condition in which HTN and proteinuria develop after 20 weeks of gestation in a previously normotensive woman, in the absence of proteinuria, preeclampsia may be defined as HTN along with: thrombocytopenia, impaired liver function, new development of renal insufficiency, pulmonary edema, new onset cerebral or visual disturbances
Onset of seizure activity or coma in a woman with preeclampsia, no history of preexisting pathology, 50% of eclampsic women develop the condition while pregnant, women can develop eclampsia in the immediate postpartum period
A condition unique to human pregnancy, common risk factors: primigravida in woman <19 or >40 yrs of age, first pregnancy with a new partner, history of preeclampsia, pregnancy onset snoring, cause unknown
