  1. Genital Tract Sepsis

  2. The Case…….. • Maria is a 21 year old primigravida at term, who presents at the labour ward in the morning with prelabour rupture of membranes (PROM) • On examination she appears well nourished, without evident anaemia • BP 110/60mmHg, Pulse 84bpm, Temperature (axillary) 36.5°C • On abdominal palpation she has a gravid, non-tender uterus, SF height of 37cm • The foetus has a cephalic presentation with 1/5 palpable over the symphysis pubis • The foetal heart rate is 144 bpm. The woman has no contractions

  3. Is a vaginal examination an essential part of the initial assessment? • No, however a sterile speculum examination may be useful to confirm PROM and take a swab if there is doubt regarding ruptured membranes • Cord prolapse is not likely as the head is engaged (cephalic 1/5 palpable) and FH rate normal • Digital vaginal examination should be avoided to minimise risk of introducing ascending infection

  4. How should this woman be further managed? • Mobilise, regular assessment of fetal movements/foetal heart rate/maternal temperature • If Preterm Prelabour Rupture of Membranes (PPROM) give antibiotics (ampicillin IV 2 gr. stat then 1 gr each 6 hours) • Induction of labour after 18 – 24 hours.

  5. Other than body temperature, what other tests could be used to monitor for the first signs of ascending genital tract infection? • Other vital signs • Maternal pulse, BP, respiratory rate • Fetal heart rate assessment • FBC • Vaginal swabs

  6. Maria establishes regular contractions after 4 hours of observation • On vaginal examination the cervix is 4cm dilated and fully effaced • After a further 4 hours of unremarkable labouring VE shows her cervix to be 5-6cm dilated • The labour is augmented with oxytocin. After a further 5 hours she gives birth to a daughter by vacuum extraction due to “maternal exhaustion” and persistent OP position

  7. An episiotomy is performed during the extraction • The delivery is complicated by an atonic uterine bleed with an estimated loss of 800mls • The bleeding is eventually controlled by ergometrine IM and cytotec tablets administered rectally • Mother and child are transferred to the postnatal area a short time later in a stable condition

  8. What aspects of her labour might predispose Maria to puerperal infections? • PROM • Ventouse extraction • Episiotomy • PPH/Anaemia

  9. On day 2 postpartum, Maria complains of headache, nausea and generalised abdominal discomfort. What examinations would you perform? • BP 110/50mmHg, Pulse 110bpm, Temp 38.2°C • The abdomen is diffusely tender, non-distended and there is no rebound tenderness • The uterus is well contracted • The lochia appears normal

  10. What information relating to this patient’s antenatal care may be of relevance in this initial evaluation? • Tetanus vaccine • Hb, is she anaemic? • Malaria prophylaxis • HIV status • Maria is managed with Fanzidar, 3 tabs STAT with malaria as a working diagnosis. A blood smear is sent. She is kept on the post-natal ward for further examination.

  11. What other clinical signs may support the diagnosis of malaria? • Anaemia • Jaundice • Splenomegaly

  12. What are life threatening complications of P. falciparum? • Profound hypoglycaemia • Cerebral malaria • Severe malaria

  13. Treatment of severe or cerebral malaria: QUININE 10 mg/kg in 5% dextrose IV over 4 hours/8 hrs As soon as patient can take orally infusion is replaced by tablets (same dose and intervals) • Treatment length: 7 days. • Monitor vital signs, blood sugar, urine output and consciousness level

  14. On day 3 the patient’s condition is worsening. She is weak, she has no appetite, her abdominal pain is worsening – which she now relates to her lower abdomen. She has no urinary symptoms but has passed some loose motions • On examination, BP 90/50mmHg, Pulse 120bpm, Temp 39.2°C. The patient seems restless with an increased respiratory rate. The chest is clear on auscultation • There is slight abdominal distention along with rebound tenderness in the lower abdomen

  15. What is the term used to describe the patient’s clinical state? • Septic shock

  16. The diagnosis of septic shock is based on clinical signs relating to disturbed physiology: • BP ↓ • Pulse ↑ • Resp. rate ↑ • Temp ↑↑ or ↓↓ • Glasgow coma scale ↓ • Oliguria

  17. Septic shock-How should this patient be managed? • Ask for help! • A – airway position so airway not occluded / at risk of aspiration • B –breathing can be supplemented with oxygen • C – circulation must be supported with IV fluids (and perhaps eventually blood). Aim for 2L in the first hour. A venous cut down may be necessary. Wide-bore IV cannulae are essential. • D – Drugs Antibiotics, consider corticosteriods

  18. IV antibiotics – as per WHO guidance: AMPICILLIN 2g/6 hrs (streptococcal infections) GENTAMYCIN 5mg/kg/24hrs (gram negatives) FLAGYL 500mg/8 hrs (clostridium and anaerobes) If in a malaria risk area treat with QUININE 10 mg/kg in 5% dextrose IV over 4 hours/8 hrs • Ideally cultures and malaria-slide should be obtained prior to the commencement of treatment Consider DEXAMETAZONE 4 mg/kg IV/6 hrs • Move patient to an area where repeated assessment can be performed (ideally ITU) and catheterise bladder to accurately measure diuresis

  19. What differential diagnoses might one consider in this scenario? • Womb: endometritis • Wound: perineum, vagina, cesarean section • Weaning: mastitis or mamma absces • Water: Urine Tract Infection • Wind: pneumonia • Walk: Venous Tromboembolism • Malaria • Meningitis

  20. What would you suspect if... • Maria had a tender uterus and foul smelling lochia? Endometritis (puerperal sepsis) • Treatment? Three course IV antibiotics Ergometrine 0.5 mg IM bd

  21. Endometritis (puerperal sepsis) • If no improvement after 24-48 hours? • Suspect retained products of pregnancy; perform evacuation under antibiotic coverage. • If still no improvement after 24 hours? • Perform laparotomy for wound revision, maybe hysterectomy.

  22. What would you do if... • Maria had a wound infection? Surgical revision (usually) and antibiotics; consider to add cloxacillin for staphylococcus aureus. Prevention? • Hygiene • Prevent anaemia • Safe obstetric and surgical techniques • AVOID CESAREAN SECTIONS AT STILBIRTHS IF POSSIBLE

  23. What would you suspect if... Maria had breast pain, tenderness and inflammation? • Mastitis Treat with... • Warm compresses • Frequent emptying of the breast, preferably by the baby, but may pump if feeding is too uncomfortable • Analgesics, rest, fluids, observation • Lactation consultation to ensure good latch and adequate emptying of breast • Antibiotics: Cloxacilline 500 mg/6 hrs for 10 days or Erythromycin 250 mg/6 hrs for 10 days
