Revision as of 01:05, 25 August 2014

Background

  • Spontaneous or induced abortion that is complicated by a pelvic infection[1]*Endometritis (2/2 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]

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/Vomitting
  • 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

Diagnosis

  • 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
  • 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[5]
  • Assess for and control any vaginal bleeding
  • Broad-spectrum antibiotics – Ampicillin 1-2 gm IV + Gentamicin 1-2 mg/kg IV + Clindamycin 600-900 mg IV or Metronidazole 500 mg 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

Complications

  • Need for hysterectomy and bilateral salpingo-oophorectomy [6]
  • Acute renal failure, liver dysfunction, ARDS, multisystem organ failure
  • DIC
  • Hemorrhage requiring transfusion
  • Increased risk of ectopic pregnancy and infertility in the future
