Exam 3 - Late Postpartum Complications Flashcards
(49 cards)
What would be considered a postpartum infection?
Any infection of the genital tract following childbirth, spontaneous abortion, pregnancy termination
- Commonly occur during first few weeks postpartum
Common sites of infection following vaginal delivery
- Perineal laceration
- Episiotomies
- Placental implantation site
Common causative agents of postpartum infections
- Steptococcus species, s. aureus, s. epidermidis
- Gram negative aerobes
- E. coli
- Klebsiella pneumoniae
- Enterobacter cloacae
- Proteus mirabilis
- Mycoplasma, chlamydia, gonorrhea
Signs and symptoms of postpartum infection
- Elevated temperature
- Malaise
- Pain
- Malodorous lochia
Risk factors of endometritis
- C-section
- Prolonged labor
- Frequent vaginal exams
- Retained placental fragments
Signs and symptoms of endometritis
- Generalized malaise
- Fever
- Chills
- Flu-like symptoms
- Foul smelling lochia
- Uterine tenderness
Labs and imagins used to manage endometritis
- Urine culture and sensitivity
- Blood cultures
- CBC
- Chest x-ray to rule out PNA
Pharmacological treatment for endometritis
IV antibiotics - clindamycin and gentamicin
What happens to patients with undiagnosed/untreated endometritis?
Can lead to salpingitis, septic thrombophlebitis, peritonitis, necrotizing fascitis
What causes postpartum women to develop UTI and pyelonephritis?
Urinary stasis from decreased bladder tone, increased bladder volume
- Particularly following epidural anesthesia, incomplete bladder emptying during labor, urethral catheterization
UTI symptoms
- Urinary frequency
- Urgency
- Dysuria
- Super pubic pain or pressure
Pyelonephritis symptoms
- Low grade fever
- Flank pain
- CVA tenderness
- N/V
What is uterine subinvolution?
Failure of uterus to return to pre-pregnancy size during 4-6 week postpartum period
What causes uterine subinvolution?
Uterine myometrium does not contract effectively
- Due to retained placental fragments, infection, excessive maternal activity
Subinvolution occuring at placental site can cause bleeding due to?
Inadequate sloughing and regeneration of endothelial lining up to 4-6 weeks after birth
- Involution normally occurs by week 2
Clinical presenation of uterine subinvolution
- Extended period of lochial discharge followed by heavy irregular bleeding
- Boggy uterus or larger than expected
- Symptoms resemble uterine infection
- Malodorous discharge
- Adnexal, cervical, uterine tenderness
What should be done for a patient with uterine subinvolution and infection is suspected?
Obtain cultures and treat with broad spectrum antibiotics
If retained placental fragments are a concern for patients with uterine subinvolution, what should be done?
Obtain ultrasound and refer
Pharmacological treatment for women with uterine subinvolution and excessive bleeding
Ergonovine (ergotrate) or methylergonovine (methergine)
What counts as delayed (secondary) postpartum hemorrhage?
Increased bleeding after first 24 hours to 12 weeks
- Most commonly occurs during first 2 weeks due to subinvolution
Signs and symptoms of delayed (secondary) postpartum hemorhage
- Excessive vaginal bleeding
- Signs of shock
- Anemia
Delayed (secondary) postpartum hemorrhage: risk factors
- Retained placental fragments
- Previously undiagnosed vaginal/cervical laceration
- Hematoma
- Uterine infection
- Uterine atony
- Coagulopathy (vWD)
What labs should be collected for patients with delayed (secondary) postpartum hemorrhage?
If no other source of bleeding can be identified, consider
- CBC, platelet count, PTT, PT in fibrinogen
What causes DVT during the postpartum period?
- Venous stasis from relaxed vascular walls in pregnancy
- Hormonal influence
- Hypercoagulopathy
- Vascular trauma from inflammation
