Definition

A procedure used for uterine evacuation and endometrial sampling consisting of a hand held vacuum syringe and flexible plastic cannullae.

Also referred to as “A Technology that saves women's lives.”

Advantages of MVA

Can be used in outpatient settings, thus increasing women's access to care

A quick and simple method of removing retained products of conception

A safe method because it has rare minimal complications such as severe bleeding, pelvic infection, cervical injury and uterine perforation

Advantages of MVA Cont’

Cheap - does not require electricity, specialized equipment, uses milder levels of medication than dilatation and curettage

Effective for endometrial biopsy because it yields high samples

Increases access to abortion care because it can be performed at lower level health care facilities

Advantages of MVA Cont’

Conserves resources since MVA reduces cost of treating incomplete abortion by decreasing the woman's hospital stay.

Contraindications

• Serious complications resulting from unsafe abortion e.g. shock, uterine perforation or sepsis- should be identified and treated before uterine evacuation is attempted

• Large fibroids

• History of bleeding disorder and severe anemia- MVA should be used with caution in health facilities with full emergency backup

MVA Equipment and Uses

• Single and double valve syringes - used for treatment of incomplete abortion up to 8 weeks from the last menstrual period (LMP) confirmed by bimanual examination

• The double valve syringe - used for MVA in the treatment of incomplete abortion up to 12 weeks LMP

• The single valve syringes are also appropriate for use in obtaining an endometrial biopsy

Preparing MVA Equipment

1. Select cannula according to the assessment of uterine size (weeks LMP)

For treatment of incomplete abortion the cannula should be large enough to allow passage of tissue expected (according to gestation) and to fit snugly through the cervix

Select the largest cannula you can comfortably use

2. Inspect cannula for cracks or defects. Discard if there are any visible signs of weakness or wear

3. Select syringes and adaptors (if needed) according to the above chart. Useful to prepare two syringes in case one is worn or defective.

Note that the colored dots on the cannulae match the color of the appropriate adapter.

4. Inspect syringes. The syringe must be able to hold a vacuum. Discard syringes with any visible cracks or defects, or ones that do not hold a vacuum

5. Attach the adaptor (if required) to the end of the syringe or cannula.

6. Check plunger and valve. The plunger should be positioned all the way into the barrel, and the pinch valve should be open with the valve button out

7. Close the pinch valve by pushing the button down and forward until you hear a lock into place.

8. prepare the syringe by grasping the barrel and pulling back on the plunger until the arms of the plunger snap outward

9. plunger arms must be fully secured over the edge of the barrel, so the plunger cannot move forward accidentally.

Incorrect positioning of the arms could allow them to slip back inside the barrel, possibly pushing air or the contents into the uterus

Never grasp the syringe by the plunger arms

10.Check the syringe for vacuum tightness before use by preparing the syringe as in steps 3-7

Set the arms and leave the syringe that way for several minutes

Then open the pinch valve

You should hear a rush of air into syringe. Indicating there was a vacuum in the syringe

Where possible, strain and rinse the aspirated tissue to remove blood and clots before placing in a clear receptacle of clean water, saline solution or weak vinegar

Inspect the tissue (villi, fetal membranes, endometrial tissue and fetal parts (after 9 weeks LMP)

Monitor Recovery

In uncomplicated case:Take vital sings while woman is still on the

treatment tableAllow woman to rest comfortably

Check the bleeding at least once before discharge

Check that clamping has diminished. Prolonged clamping is abnormal

Monitor Recovery cont’

If the woman is Rh negative, administer Rh immune globulin

Before the woman leaves the facility she should be provided information about:

Family planning services including counseling and initiation of a contraceptive method, if she wants to use one.

Monitor Recovery Cont’

Signs of normal recovery (some uterine cramping over the next few days, some spotting or bleeding that shouldn’t be more than a normal period)

A normal menstrual period will occur within 4- 8 weeks.

Symptoms that require emergency care (prolonged cramping lasting more than a few days, prolonged bleeding more than 2 weeks)

Monitor Recovery Cont’Bleeding more than a normal period, severe or

increased pain, fever, chills or malaise, fainting)

Take any prescribed medication

Not having sexual intercourse until 3 days after bleeding stops

Many other reproductive health needs may be addressed at this time as well like screening for cervical cancer,

Monitor Recovery Cont’

Identification and treatment of reproductive tract infections

Patient may be discharged as soon as she is stable, can walk without assistance and has received follow up information.

TECHNICAL COMPLICATIONS

Vacuum is lost

In most MVA procedures, the syringe vacuum remains constant until the syringe is approximately 80% full (50cc)

Loss of vacuum during the procedure can be caused by the syringe becoming full or the cannula being accidentally withdrawn from the cervical os

What to do when vacuum is lost

Close the valves

Disconnect the syringe from the cannula. Leave the cannula tip in place and do not push in the plunger

Empty the syringe contents into the receiver by openning the pinch valve and pushing the plunger into barrel

Re establish a vacuum by closing the valves and pulling back and locking the arms of the plunger

Cannula clogged

If no tissue or bubbles are flowing into the syringe , the cannula may be clogged

Remove the syringe and cannula

Examine the tip (openings of the cannula. If there is anything blocking these openings, remove the material using a sterile forcep or gauze sponge

Cannula clogged

Never try to unclog the cannula by pushing the plunger back into the barrel when the cannula is in the woman's body.
