Background
- Spontaneous or induced abortion that is complicated by a pelvic infection[1]
- Endometritis (secondary to retained products of conception or using non-sterile instruments)
- Leading to PID and peritonitis then bacteremia, sepsis, and death[2]
- Usually a polymicrobial infection[3]
- E. Coli, Streptococcus, anaerobes (Bacteroides), sexually transmitted pathogens
- Clostridium perfringens is associated with a higher mortality
- Tetanus, especially in developing nations and if nonsterile instrumentation is the cause
Risk Factors
- Non Sterile abortions
- Advanced gestational age
Epidemiology
- Huge cause of maternal mortality worldwide
- Estimated 20 million unsafe abortions performed worldwide every year; 40% done on women ages 15-24[4]
- WHO estimates 68,000 women die every year from unsafe abortions, with septic abortion being the #1 cause of death
- Overall mortality: 20-50%
- Mortality rare in US (1 in 100,000 abortions)
Clinical Features
- Abdominal or pelvic pain
- Nausea/Vomiting
- Vaginal bleeding
- Vaginal discharge
- Cervical motion tenderness
- Hypotension, tachycardia, fever, tachypnea
- History of recent pregnancy or known induced or spontaneous abortion
- Usually delayed presentation (48 hours after onset of symptoms) secondary to the stigma of induced abortion
Complications
- Need for hysterectomy and bilateral salpingo-oophorectomy [5]
- Acute renal failure, liver dysfunction, ARDS, multisystem organ failure
- DIC
- Hemorrhage requiring transfusion
- Increased risk of ectopic pregnancy and infertility in the future
Differential Diagnosis
Abdominal Pain in Pregnancy
The same abdominal pain differential as non-pregnant patients, plus:
<20 Weeks
- Ectopic pregnancy
- First trimester abortion
- Complete abortion
- Threatened abortion
- Inevitable abortion
- Incomplete abortion
- Missed abortion
- Septic abortion
- Round ligament stretching
- Incarcerated uterus
- Malposition of the uterus
>20 Weeks
- Labor/Preterm labor
- Placental abruption
- Placenta previa
- Vasa previa
- Uterine rupture
- Vaginal trauma
- HELLP syndrome
- Cholestasis of pregnancy
- Chorioamnionitis
- Incarcerated uterus
- Acute fatty liver of pregnancy
- Malposition of the uterus
- Placenta accreta
- Placenta increta
- Placenta percreta
Any time
- Hemorrhagic ovarian cyst
- Fibroid degeneration or torsion
- Ovarian torsion
- Constipation
Vaginal Bleeding in Pregnancy (>20wks)
- Emergent delivery
- Placental abruption
- Placenta previa
- Vasa previa
- Uterine rupture
- Preterm labor
- Vaginal trauma
- Placenta accreta
- Intrauterine fetal demise
3rd Trimester/Postpartum Emergencies
- Acute fatty liver of pregnancy
- Amniotic fluid embolus
- Chorioamnionitis
- Eclampsia
- HELLP syndrome
- Mastitis
- Peripartum cardiomyopathy
- Postpartum endometritis (postpartum PID)
- Postpartum headache
- Postpartum hemorrhage
- Preeclampsia
- Resuscitative hysterotomy
- Retained products of conception
- Septic abortion
- Uterine rupture
Evaluation
- Clinical diagnosis; patient may be reluctant to share information that she had an unsafe abortion
- Labs: CBC, blood type with Rh status, CMP, serum beta-hcg level, UA, blood cultures
- Gram stain and culture of any vaginal discharge
- Check coagulation panel to rule out DIC
- Pelvic exam – look for signs of trauma to cervix or vagina
- Pelvic ultrasound – check for intrauterine material, abdominal free fluid, pelvic abscess
- CT or MRI – may show uterine emphysema or intraperitoneal air if uterine perforation has occurred
Management
- 2 large bore IVs; aggressive IV fluid resuscitation[6]
- Assess for and control any vaginal bleeding
- Broad-spectrum antibiotics – ampicillin 1-2 gm IV + gentamicin 1-2mg/kg IV + clindamycin 600-900mg IV or metronidazole 500mg IV
- Tetanus vaccination
- Early OB consult – Most will need evacuation of any remaining products of conception
- Early surgery consult - Exploratory laparotomy if any pelvic free fluid or intra-abdominal air
Disposition
- Admit
