47. Pathologic puerperium. Puerperal sepsis Flashcards
name types of postpartum infections
- Endometritis
- Postpartum sepsis
- Surgical site infection (may present as superficial cellulitis, and up to necrotizing fasciitis)
- Mastitis and breast abscess
- UTI (cystitis, pyelonephritis)
in 5-7% of women
postpartum endometritis
Ascending polymicrobial infection, involving the endometrial lining or deeper tissues
(endomyometritis).
associated organisms of postpartum endometritis
enterococci, GBS, Gardnerella, aerobic streptococci, E. coli, Bacteroides, Peptostreptococci.
risk factors of postpartum endometritis
- Emergency C-section
- Prolonged ROM
- Prolonged labor
- ↑ number of cervical exams
- Group B-strep positive
- HIV positive
presentation of postpartum endometritis
Early-onset after delivery with rapid progression.
- Fever (most characteristic finding)
- Foul-smelling lochia
- HR ↑
- Pelvic tenderness
diagnosis of postpartum endometritis/ sepsis
clinical
Work-up for differential diagnosis may include: labs, urinalysis and urine culture, blood
culture, CXR, pelvic US to exclude retained POC (endometritis), pelvic CT to exclude pelvic abscess (sepsis) .

Wonder drugs Drug fever At any time
most common cause of postpartum maternal fever
endometritis
treatment of postpartum endometritis
- Admission to hospital care.
2, Antibiotic regimen: Clindamycin + Gentamycin +/- Ampicillin (if GBS positive).
*Start IV treatment until the fever subsides, continue PO treatment to complete a total of 14-days course. - Consider D&C if evidence of retained POC.
Antibiotic prophylaxis before cesarean delivery to prevent postpartum endometritis
- Cefazolin 60 min’ before skin incision in all patients.
- plus Azithromycin (if in active labor, ROM, or emergent C-section)
postpartum endometritis complications
- Sepsis
- Peritonitis
- Pelvic abscess
- Endometrial scarring (Ashermann syndrome)
The major pathogens causing sepsis in the puerperium period?
- Group A strep (S. pyogenes)
- E. coli
- S. aureus
- S. pneumoniae
- Methicillin-resistant S. aureus (MRSA)
risk factors for postpartum sepsis
- D.M.
- Obesity
- Immunocompromised state
- Prolonged ROM
- C-section
- Retained POC
presentation of postpartum sepsis
- Fever, rigors
- Diarrhea or vomiting – may indicate exotoxin production (early toxic shock)
- Breast engorgement/redness
- Rash (generalized maculopapular rash)
- Abdominal/pelvic pain and tenderness
- Wound infection – spreading cellulitis or discharge
- Offensive vaginal discharge
- Productive cough
- Urinary symptoms
treatment for postpartum sepsis
- Hospital/ICU admission.
- Antibiotic regimen: Piperacillin/Tazobactam OR Carbapenem + Clindamycin.
**Add Vancomycin if MRSA infection is suspected or documented. - IVIG is recommended for severe invasive streptococcal or staphylococcal infection if other therapies have failed.
- Address underlying infectious foci if identified.
