MANAGING COMPLICATIONS ASSOCIATED WITH MEDICATION ABORTION

Complication Clinical Presentation Management Options Occurrence Rate
Problematic bleeding and/or cramping
  • Prolonged cramping, pain and/or bleeding
  • Retained gestational sac or tissue may be seen on US; inappropriate decline in hCG
  • Expectant management
  • Repeat misoprostol
  • Uterine aspiration
2-9%
(varies by study & GA)
Continuing Pregnancy
  • May have scant bleeding after medications, persistent pregnancy symptoms
  • Ongoing viable intrauterine pregnancy (growing gestational sac or cardiac activity on US; rapidly rising hCG)
  • Uterine aspiration
  • Repeat misoprostol (if embryonic pole seen, expulsion occurred in 36% with and 54% without gestational cardiac activity after one dose)1
  • Consider repeating misoprostol dosing until pregnancy expelled
≤63 d: <3.1%2,3

64-70 d:
3.6% with 1 dose, 0.4% with 2 doses2,3

71-77 d: 8.7% with 1 dose, 1.6% with 2 doses3

 

Endometritis
  • Typical endometritis: fever (>24 hours after misoprostol), pelvic/abdominal pain, vaginal discharge with odor, uterine/adnexal tenderness
    • Atypical endometritis: included here for historical importance. Etiology: Clostridium sordelii or perfringens-mediated toxic shock syndrome; can be severe or fatal.
    • Occurs 2-7 days after MAB
    • Symptoms: nausea, abdominal bloating, diarrhea, pain, malaise
    • Signs: usually afebrile, tachycardic, hypotensive, elevated WBC
  • May follow CDC guidelines for antibiotic therapy for PID
    • Outpatient regimen: Ceftriaxone 500mg IM x1 dose + doxycycline 100mg BID x14d + metronidazole 500mg BID x14d
  • Uterine aspiration if retained tissue present
  • Immediate hospitalization and aggressive treatment for atypical infection
0.01-0.5%2

< 10 case reports by CDC4

Ectopic Pregnancy
  • May be asymptomatic or present with minimal bleeding or inappropriate decline in hCG after misoprostol, persistent positive UPT
  • May present with pelvic/abdominal pain, history of bleeding or spotting during the pregnancy, shoulder pain, tachycardia/hypotension.
  • Treat or refer as appropriate
  • Low threshold to have patient evaluated in the ER if suspected ectopic pregnancy
  • Asymptomatic meeting criteria may be treated with methotrexate (see Access Bridge treatment protocols and/or refer to GYN)
0.6%
(in study of GA < 6 weeks in the U.S.)2
Excessive Bleeding
  • Heavy or prolonged vaginal bleeding with associated signs or symptoms (may include Hgb drop >2 points, orthostatic hypotension, tachycardia)
  • True hemorrhage is rare, but is a life-threatening emergency
  • May result from retained pregnancy tissue; may present 2-5 weeks after misoprostol
  • Medical management (misoprostol, NSAIDs)
  • Uterine aspiration
  • Iron supplementation
<1%2
  • Blood transfusion
  • Iron supplementation
<0.02-0.6% 2
