PPH risk assessment: low risk
- no previous uterine incision (no c/s hx)
- singleton pregnancy
- </= 4 previous vaginal births
- no known bleeding disorders
- no history of PPH
PPH risk assessment: medium risk
- induction of labor with oxytocin or cervical ripening
- multiple gestation
- > 4 vaginal births
- prior c/s or uterine incision
- large uterine fibroids
- hx of one previous PPH
- family hx in first degree relatives who experience PPH
- chorioamnionitis
- fetal demise
- polyhydramnios
PPH risk assessment: high risk
- has 2+ medium risk factors
- active bleeding more than “bloody show”
- suspected placenta accreta or percreta
- placenta previa or low-lying placenta
- known coagulopathy
- hx of more than one PPH
- hematocrit < 30 AND other risk factors
- platelets < 100,000/mm3
anticipatory interventions: low risk PPH
none
anticipatory interventions: medium risk PPH
- notify appropriate personnel- provider, anesthesia, blood bank, charge nurse, clinical nurse specialist
anticipatory interventions: high risk PPH
- notify appropriate personnel- provider, anesthesia, blood bank, charge nurse, clinical nurse specialist
- consider delivery at a facility with the appropriate level of care capable of managing a high risk mother
how much blood loss constitutes postpartum hemorrhage?
> 500 mL: vaginal delivery
750-1000 mL: c/s
what are the two approaches to hemorrhage?
- resuscitation and management
- identify the cause (figure out: why?)
risk factors that cause PPH
- macrosomia
- placenta abnormalities
- multiple gestation
- previous uterine surgery (c/s- think weakening of the uterine lining)
- prior PPH
- high parity (how many times they have been pregnant)
- precipitous labor/birth (< 3 hours)
what are the 4 T’s to identify the cause of PPH?
tone
tissue
trauma
thrombosis (clotting)
PPH causes: what is tone?
uterine atony
PPH causes: what is tissue?
retained placenta
PPH causes: what is trauma?
lacerations, hematomas
PPH causes: what is thrombin?
coagulation
stage 1 PPH
- blood loss: > 500 mL vaginal or >1000 mL c/s
- normal VS and labs
stage 2 PPH
- continues to bleed, >1000 mL vaginal or >1500 mL c/s blood loss
- > 2 uterotonics
- monitoring VS and labs
- 2 units Type specific blood
stage 3 PPH
- continues to bleed, >1500 mL blood loss
- > 1 unit of packed RBC: 1-unit FFP
- abnormal VS and labs
stage 4 PPH
- cardiovascular collapse
- profound hypovolemic shock
- amniotic embolism (will also see DIC)
lacerations and hematomas: risk factors
- large baby
- operative vaginal delivery
- precipitous labor
hematoma in the vaginal canal
- cannot be visualized by the nurse
- women express severe pain, heaviness in the vagina and rectal pressure
- might see discoloration and tenderness
retained placental tissue is at an increased risk when the placenta is _____
removed manually
what is the primary cause of PPH?
retained placental tissue
signs of retained placental tissue
- profuse bleeding after the first week postpartum
- subinvolution of the uterus
- elevated temperature (100.4)
- tachycardia
- hypotension
interventions for retained placental tissue
- D&C
- IV antibiotics
coagulation disorders
- DIC
- anaphylactoid syndrome
- venous thromboembolic disease (VTE)
-two types: DVT and PE
DVT and PE testing
doppler studies
DVT and PE treatment
- anticoagulation therapy
- elastic stockings
wound infections can come from
- laceration
- episiotomy
- c/s incision
risk factors for wound infections
- obesity
- DM
- malnutrition
- long labor
- pre-existing infection
symptoms of wound infections
- erythema
- heat
- swelling
- tenderness
- drainage (want to send to lab)
- low grade fever
- increased pain
what types of bacteria cause wound infection?
staphylococcus or streptococcus
mastitis
inflammation or infection of the breast tissue in lactating women
- staphylococcus
symptoms of mastitis
- tender, engorged and erythematous breast
nurse actions: mastitis
- keep breastfeeding
