This page details information about these procedure abortions. The gestational age limit for MVA often depends on the clinic, as well as the healthcare provider performing the procedure. During the procedure the clinician uses instruments, including a silent suction device, to remove the pregnancy from the uterus [2].
Most commonly this procedure is performed using local anaesthesia while the woman is awake, and it takes typically between 5 and 10 minutes. The woman is likely to experience cramping during the procedure, and there may be some bleeding on and off for several days or weeks afterwards.
MVA is Manual Vacuum Aspiration but it might also be known as surgical abortion, aspiration abortion, suction abortion, vacuum aspiration procedure abortion, or in-clinic abortion. EVA is performed by a trained provider in a clinic. During the procedure, the clinician uses instruments, including an electric vacuum suction to remove the pregnancy from the uterus.
Because the EVA requires electricity, it may not be available in low-resource settings. Where available, clinicians may use this method of EVA as the gestational age increases after weeks because it allows the clinician to perform the procedure more quickly than the MVA, and thus decreases the procedure duration for the woman.
Another significant difference is that there is noise associated with the EVA machine because it uses electricity. The World Health Organization WHO recommends administering antibiotics prior to manual vacuum aspiration and electric vacuum aspiration. This helps to reduce the risk of infection.
However, if antibiotics are unavailable, a vacuum aspiration abortion can still safely be performed. Clinics may also choose to give an oral medication to help with the cramping pain, such as Ibuprofen. During a clinic visit for a manual vacuum aspiration abortion MVA or an electric vacuum aspiration abortion EVA , there are often steps taken in preparation for the procedure including but not limited to [2]:. Step 1. The manual vacuum aspiration abortion MVA or the electric vacuum aspiration abortion EVA procedures will begin with a pelvic or speculum exam.
For example, at 10 weeks LMP, choose a cannula that is 8 to 10 mm in diameter. For example, if at 10 weeks LMP it is only possible to easily dilate up to a No. Injections for the paracervical block are given in this transition zone.
Dilate the cervix if the cervical canal cannot accommodate the cannula appropriate for gestational age or the size of the uterus. Dilation should be smooth and gradual: — With one hand, pull the forceps attached to the cervix and keep traction in order to bring the cervix and the uterine body into the best possible alignment.
Continue in this way, using the next size dilator each time, until obtaining dilation appropriate to the cannula to be inserted, without ever relaxing the traction on the cervix. A loss of resistance may be felt: this indicates that there is no need to advance the dilator any further. This loss of resistance is not necessarily felt. In such case, it can be assumed that the internal os has been penetrated when the dilator has been inserted 5 cm beyond the external os.
Rotating the cannula while applying gentle pressure facilitates insertion. Slowly and cautiously push the cannula into the uterine cavity until it touches the fundus ; then pull back 1 cm. The contents of the uterus should be visible through the syringe blood and the whitish products of conception.
Nearly 90 out of abortions are done in the first trimester of pregnancy. The hospital or surgery center may send you instructions on how to get ready for your surgery. Or a nurse may call you with instructions before your surgery. Right after surgery, you will be taken to a recovery area where nurses will care for and observe you.
You most likely will stay in the recovery area for a period of time and then you will go home. In addition to any special instructions from your doctor, your nurse will explain information to help you in your recovery.
You will go home with a page of care instructions including who to contact if a problem arises. An abortion rarely affects your ability to become pregnant in the future. So it is possible to become pregnant in the weeks right after the procedure. Avoid sexual intercourse until your body has fully recovered, usually for at least 1 week. Use birth control in the first weeks following the abortion.
And use condoms to prevent infection. Depression can be triggered when pregnancy hormones change after an abortion. If you have more than 2 weeks of symptoms of depression, such as fatigue, sleep or appetite change, or feelings of sadness, emptiness, anxiety, or irritability, see your doctor about treatment.

Surgery Overview There are two methods of vacuum aspiration also called suction aspiration : Manual vacuum. This procedure can be used around 5 to 12 weeks after the last menstrual period early first trimester. It involves the use of a specially designed syringe to apply suction.
This method is not available everywhere. But it may be more available than machine aspiration in some geographic areas.
Machine vacuum. This procedure is a common method used in the first 5 to 12 weeks first trimester of pregnancy. Machine vacuum aspiration involves the use of a thin tube cannula that is attached by tubing to a bottle and a pump, which provides a gentle vacuum.
The cannula is passed into the uterus, the pump is turned on, and the tissue is gently removed from the uterus. Vacuum aspiration procedure Hours before or the day before a vacuum aspiration procedure, a cervical osmotic dilator may be placed in the cervix to slowly open dilate it. For this procedure, the health professional will: Position you on the exam table in the same position used for a pelvic exam, with your feet on stirrups while lying on your back.
Insert a speculum into the vagina. Clean the vagina and cervix with an antiseptic solution. Inject a numbing medicine local anesthetic in the cervix.
Medicine for pain or sedation, in addition to the local anesthetic, may be given by mouth or through a vein intravenously. Vasopressin, or a similar medicine that slows uterine bleeding, may be mixed with the local anesthetic to reduce blood loss. Grasp the cervix with an instrument to hold the uterus in place. Open dilate the cervical canal with a small instrument. Dilation reduces the risk of any injury to the cervix during the procedure.
