Last edited 02/2022 and last reviewed 02/2022
Initial assessment
- The first step in pre abortion management is to confirm the pregnancy by establishing a history of amenorrhoea and early pregnancy symptoms such as nausea, breast tenderness, fatigue and a reliable urine pregnancy test.
- Pre-abortion assessment includes:
- rhesus blood status
- where clinically indicated
- determination of blood group with screening for red cell antibodies
- measurement of haemoglobin concentration
- testing for haemoglobinopathies
- venous thromboembolism (VTE) risk assessment
- Women who have not had cervical cytology screening within the recommended interval should be offered screening within the abortion service, or advised on when and where to obtain it.
- Use of routine pre-abortion ultrasound scanning is unnecessary but must be available to all services as it may be required as part of the assessment.
Prevention of infective complications
- Services should offer antibiotic prophylaxis effective against C. trachomatis and anaerobes for both surgical abortion and medical abortion. The following regimens are suitable for peri-abortion antibiotic prophylaxis:
- azithromycin 1 g orally on the day of abortion plus metronidazole 1 g rectally or 800 mg orally prior to or at the time of abortion OR
- doxycycline 100 mg orally twice daily for 7 days starting on the day of abortion, plus metronidazole 1 g rectally or 800 mg orally prior to or at the time of abortion OR
- metronidazole 1 g rectally or 800 mg orally prior to or at the time of abortion for women who have tested negative for C. trachomatis infection
- All women should be screened for C. trachomatis and undergo a risk assessment for other STIs (such as HIV, gonorrhoea, syphilis).
Contraception
- All appropriate methods of contraception should be discussed with women at the initial assessment and a plan for contraception after the abortion (1).
Feticide
- Feticide (destruction of fetus in the uterus) should be performed after 21 weeks and 6 days of gestation to ensure no risk of live birth.
