Fact
Vacuum aspiration abortion
Vacuum aspiration is a short procedure that ends a pregnancy by emptying the uterus using gentle suction. It is the procedure most often used earlier in pregnancy, it does not involve an incision, and it is normally done with the person awake and with some form of pain relief. The appointment usually takes a few hours even though the procedure itself is short.
This page describes vacuum aspiration in general, non-graphic terms. It does not describe what any specific clinic does, and it is not a substitute for the explanation a clinical team gives before a procedure.
What it is
Vacuum aspiration empties the uterus using gentle suction applied through the cervix. It is also called aspiration abortion or suction abortion. It is the procedure used most often earlier in pregnancy.
There is no incision, which is why calling it surgery is inaccurate. The suction may be produced by a hand-held device or by an electric pump. Both are established approaches, and which one is used depends on the facility and the situation.
The same procedure has other uses
Vacuum aspiration is not used only for abortion. The same procedure is used to complete a miscarriage, and to manage some other conditions of the uterus. That matters for two reasons: a person may encounter the term in a context that has nothing to do with abortion, and the phrase "D&C", which people often use for all of these, is not a synonym for it.
The glossary sets out where D&C and vacuum aspiration overlap and where they differ.
When it is usually used
Vacuum aspiration is used earlier in pregnancy. The exact range depends on clinical guidance, the facility, and the individual situation. Later in pregnancy the usual procedure becomes dilation and evacuation.
The length of the pregnancy is normally confirmed before the procedure, usually with an ultrasound, because it affects which procedure is appropriate.
What preparation can involve
- Confirming the pregnancy and its duration, usually with an ultrasound.
- A health history review, including current medicines and allergies.
- Consent, including a conversation about what the procedure involves and what the alternatives are.
- Preparing the cervix. Depending on the situation, medicines may be given beforehand to soften the cervix. Whether this is used, and how far in advance, is a clinical decision.
- Instructions for the day, such as whether to eat beforehand. These come from the facility, and they vary, particularly when sedation is planned.
What the procedure involves, in outline
The person is positioned as for a pelvic examination. A speculum is used. The cervix is usually numbed with a local anaesthetic. The cervix is gently opened enough to admit a thin tube. Suction is applied through the tube for a short time to empty the uterus.
The suction part is typically brief, often just a few minutes. The appointment overall is much longer because of preparation, monitoring, and recovery time.
Sensations vary. Many people describe cramping that builds during the procedure and eases fairly quickly afterwards. Some find it uncomfortable rather than painful. Some find it painful. What is used for comfort makes a considerable difference, and it is worth asking what a facility offers.
Comfort options
Depending on the facility, options can include a local anaesthetic at the cervix, oral pain medicines taken beforehand, anti-anxiety medicine, moderate sedation, or deeper anaesthesia. Availability differs between services, and the choice also depends on health history.
If sedation deeper than local anaesthetic is used, someone else will normally need to take you home. Plan for that in advance.
Recovery in general terms
- Most services monitor the person for a period afterwards before discharge.
- Cramping usually eases over the hours that follow, and over-the-counter pain medicine is often enough. Follow the instructions given by the clinical team.
- Bleeding varies. Some people bleed lightly for a few days, others for a few weeks, and some have very little bleeding at all. The recovery page covers general patterns.
- Completion is normally confirmed by the clinical team at the time.
The clinical team gives instructions for the days afterwards, including what to do about activity and what to watch for. Those instructions come from the people who know the individual situation, and they take priority over anything written here.
Risks and when to seek help
Vacuum aspiration is a common procedure, and serious complications are uncommon. Uncommon is not the same as impossible, and this site does not make an unconditional safety claim about any procedure. The safety page explains the difference between a common effect and a complication, and what the evidence supports.
The signs that mean contacting a clinician urgently, and the signs that mean emergency medical help, are set out on the urgent help page.
Questions worth asking
- Which procedure is planned for me, and why that one?
- What is offered here for pain and anxiety?
- Will I need someone to take me home?
- How long should I plan to be at the facility?
- What should I expect over the following days?
- Who do I contact if I am worried, including at night or at the weekend?
