## Direct answer

Surgical abortion methods in India include manual vacuum aspiration, electric vacuum aspiration or suction evacuation, and dilatation and evacuation, chosen mainly by gestational age. Manual vacuum aspiration suits pregnancies up to about 12 weeks, suction evacuation extends to about 14 weeks, and dilatation and evacuation is the standard second-trimester method. Each method carries a distinct main risk, which exam questions often test.

## What you must remember

- **Manual vacuum aspiration (MVA):** handheld syringe, usually up to about 12 weeks, and can be done under local anaesthesia with a paracervical block.
- **Electric vacuum aspiration (EVA):** suction evacuation with an electric pump, used up to about 14 weeks.
- **Dilatation and evacuation (D&E):** cervical preparation, dilatation, then removal of tissue with forceps and suction, used in the second trimester.
- **Cervical preparation:** osmotic dilators or misoprostol reduce the risk of cervical injury before D&E.
- **Main complications:** incomplete evacuation, haemorrhage, cervical injury, uterine perforation and infection.
- **After the procedure:** check bleeding, Rh status for anti-D, and offer contraception counselling.

## Choosing the method by gestation

The method is chosen by gestational age and by the setting in which it is performed. The table compares the three methods on the points most often tested.

| Method | Typical gestation | Setting | Main risk |
|---|---|---|---|
| MVA | Up to about 12 weeks | Outpatient, local anaesthesia | Incomplete evacuation |
| EVA or suction | Up to about 14 weeks | Operating room, electric pump | Perforation and haemorrhage |
| D&E | Beyond about 14 weeks | Operating room, cervical preparation | Cervical injury and haemorrhage |

Gestational age is the main decision point, and a method is not chosen for a pregnancy beyond its safe range. 

Surgical technique must match the stage, and dating errors are a common reason for choosing the wrong method. Vignettes give the gestational age first, so precise dating matters. Equipment and theatre access then decide where the procedure can safely be done, which is why MVA is often offered in primary care. A pregnancy test, blood group and counselling apply to every method.

## Where the exam tries to catch you

Questions in this area test the gestational limit of each method and the equipment each one needs.

- **Trap:** Assuming MVA needs electricity or general anaesthesia. **Correct:** MVA uses a hand syringe and can be done under local anaesthesia, which is why it suits low-resource settings.
- **Trap:** Choosing MVA for a 16-week pregnancy. **Correct:** MVA is limited to early gestation, and D&E is used in the second trimester.
- **Trap:** Skipping cervical preparation before D&E. **Correct:** Osmotic dilators or misoprostol reduce cervical injury during D&E.

## Frequently asked questions

### What is the upper gestational limit for manual vacuum aspiration?

Manual vacuum aspiration is usually used up to about 12 weeks of gestation. Some services extend it slightly with appropriate training. Beyond that point, suction evacuation or dilatation and evacuation is preferred.

### Why is manual vacuum aspiration suited to low-resource settings?

Manual vacuum aspiration uses a hand-operated syringe rather than an electric pump. It can be done under local anaesthesia in an outpatient setting. Manual vacuum aspiration is therefore widely used for early pregnancy termination where electricity or theatres are limited.

### When is dilatation and evacuation used?

Dilatation and evacuation is the standard surgical method in the second trimester, beyond about 14 weeks. It involves cervical preparation, then dilatation and removal of tissue with forceps and suction. Cervical injury and haemorrhage are its main risks.

### What complications follow surgical abortion?

Incomplete evacuation, haemorrhage, cervical injury, uterine perforation and infection are the main complications of surgical abortion. Post-procedure checks include bleeding, fever and Rh status. Choosing the method by correct gestational age reduces these complications.
