  1. FEVER AFTER LABOR Dianne MP Graham, MD, CCFP Kelowna, BC, Canada Based on WHO Document on Managing Complications In Pregnancy, 2000

  2. WHAT ARE THE CAUSES OF POSTPARTUM FEVER & SEPSIS? • Endometritis, Pelvic Abscess, Peritonitis • Breast engorgement, Mastitis & Breast Abscess • Wound cellulitis, Wound Hematoma, Wound Abscess • Cystitis and Acute Pyelonephritis • Deep Vein Thrombosis • Pneumonia & Atelectasis • Uncomplicated & Severe Complicated Malaria • Typhoid & Hepatitis

  3. ENDOMETRITIS • Endometritis is infection of the uterus after delivery and is a major cause of maternal death • Multiple factors contribute to this including poor sterile technique, excessive internal exams, prolonged labors • Delayed or inadequate treatment can lead to pelvic abscess, peritonitis, septic shock, deep vein thrombosis, pulmonary embolism, chronic pelvic infection with pain and or infertility

  4. ENDOMETRITIS • Signs: Fever/chills, lower abdominal pain, purulent/foul smelling lochia, tender uterus • Less Frequent Signs: Increased bleeding & shock • Treatment: -Give a combination of drugs until patient is fever free for 48 hours: • -ampicillin 2 gm IV every 6 hours • -PLUS gentamycin 5 mg/kg body wt every 24 hr • -PLUS metronidazole 500 mg IV every 8 hours

  5. ENDOMETRITIS TREATMENT • If fever continues 72 hours after starting antibiotics re-evaluate and revise diagnosis • Possible complications include pelvic abscess or peritonitis which may need further intervention • NOTE: Oral antibiotics are NOT necessary after stopping IV antibiotics

  6. BREAST INFECTIONS • SIGNS: - breast pain and tenderness with onset often 3 to 4 weeks after delivery • -reddened, wedge-shaped area on breast • -usually only one breast involved • -fever often rapid onset and high >38.5 • TREATMEMT: cloxacillin 500 mg orally four times daily for ten days OR erythromycin 250 mg three times a day for ten days

  7. MASTITIS • continue breast feeding • support breasts with binder or brassiere • apply cold compresses to breasts between feeds • give paracetamol 500 mg by mouth as needed • NOTE: Follow patient up in 3 days to ensure response

  8. INFECTION OF PERINEAL AND ABDOMENAL WOUNDS • If there is pus or fluid open and drain the wound • Remove infected skin or subcutaneous sutures & debride the wound. Do not remove fascia sutures. • If there is an abscess without cellulitis antibiotics are not needed • Place a damp dressing in the wound & have the woman return to change dressing every 24 hours • Woman needs to maintain good hygiene & wear clean pads or cloths that she changes often

  9. WOUND CELLULITIS • If there is fluid or pus open & drain the wound • Remove infected skin or subcutaneous sutures & debride the wound. Do not remove fascia sutures • If infection is superficial and does not involve deep tissues monitor for development of an abscess and give • - ampicillin 500 mg po QID for five days • - PLUS metronidazole 400 mg 3x daily for 5 days

  10. SEVERE DEEP WOUND INFECTIONS OR NECROTIZING FASCIITIS • Always involves muscles and is causing necrosis • If not properly treated usually leads to fistulas with bladder, bowel or abdomen • Necrotizing fasciitis requires wide surgical debridement • If woman has necrotizing fasciitis admit to hospital for management and change dressings twice daily

  11. MEDICAL TREATMENT OF NECROTIZING FASCIITIS OF WOUNDS • Give in combination with debriding necrotic tissue until patient is fever free for 48 hours: • - penicillin G 2 million units IV every 6 hours • - PLUS gentamicin 5 mg/kg body weight IV every 24 hours • - PLUS metronidazole 500 mg IV every 8 hours

  12. NECROTIZING FASCIITIS TREATMENT • ONCE WOMAN IS FEVER FREE FOR 48 HOURS give: • ampicillin 500 mg by mouth four times daily for five days • PLUS metronidazole 400 mg by mouth three times per day for five days

  13. ACUTE PYELONEPHRITIS • Is an infection of the upper urinary tract • Common signs: Dysuria, spiking fever/chills, increased urinary frequency & urgency of urination, abdominal pain • Less common signs: retro pubic/suprapubic pain, loin pain/tenderness, loss of appetite, nausea/vomiting

  14. TREATMENT OF ACUTE PYELONEPHRITIS • Start IV fluids at 150 ml per hour • If available get urine and blood cultures first . If not treat with IV antibiotics until patient is fever free 48 hours • ampicillin 2 gm IV every 6 hours • PLUS gentamycin 5 mg/kg patient weight IV every 24 hours • Once patient is afebrile 48 hours give amoxicillin by mouth 1 gm 3X daily for 14 days

  15. Pneumonia • Pneumonia is a radiological diagnosis. Suspect it and get a chest x-ray if possible for any unexplained fever. • Common signs: fever, difficulty breathing, cough with expectoration, chest pain, consolidation, rapid breathing, rhonchi/rales, throat congestion • Give erythromycin 500 mg 3X daily for seven days • Ampicillin 1 gm 3X daily for seven days is an alternative

  16. UNCOMPLICATED MALARIA • Plasmodium falciparum and P. vivax cause the majority of diseases • Plasmodium falciparum in pregnant/post-partum women can cause severe disease and death if not recognized and treated early • Malaria should be considered the most likely diagnosis in a pregnant woman with fever who has been exposed to malaria • Confirm diagnosis with thin and thick slides or rapid antigen tests

  17. SIGNS OF UNCOMPLICATED MALARIA • Fever • Chills/rigors • Headache • Muscle/joint pain • Enlarged spleen
