Vacuum delivery and Manual vacuum aspiration
Vacuum delivery
A vacuum extraction is a procedure sometimes done during the course of vaginal childbirth.
During vacuum extraction, a health care provider applies the vacuum — a soft or rigid cup with a handle and a vacuum pump — to the baby's head to help guide the baby out of the birth canal. This is typically done during a contraction while the mother pushes.
Your health care provider might recommend vacuum extraction during the second stage of labor — when you're pushing — if labor isn't progressing or if the baby's health depends on an immediate delivery.
Vacuum extraction poses a risk of injury for both mother and baby. If vacuum extraction fails, a cesarean delivery (C-section) might be needed.
Why it's done
A vacuum extraction might be considered if your labor meets certain criteria — your cervix is fully dilated, your membranes have ruptured and your baby has descended into the birth canal headfirst, but you're not able to push the baby out. A vacuum extraction is only appropriate in a birthing center or hospital where a C-section can be done, if needed.

Your health care provider might recommend vacuum extraction if:
You're pushing, but labor isn't progressing. If you've never given birth before, labor is considered stalled if you've pushed for a period of two to three hours but haven't made any progress. If you've given birth before, labor might be considered stalled if you've pushed for a period of one to two hours without any progress.Your baby's heartbeat suggests a problem. If your health care provider is concerned about changes in your baby's heartbeat and an immediate delivery is necessary, he or she might recommend vacuum extraction.You have a health concern. If you have certain medical conditions — such as narrowing of the heart's aortic valve (aortic valve stenosis) — your health care provider might limit the amount of time you push.
Keep in mind that whenever vacuum extraction is recommended, a C-section is typically also an option.
Your health care provider might caution against vacuum extraction if:
You're less than 34 weeks pregnantYour baby has previously had blood taken from his or her scalp (fetal scalp sampling)Your baby has a condition that affects the strength of his or her bones, such as osteogenesis imperfecta, or a bleeding disorder, such as hemophiliaYour baby's head hasn't yet moved past the midpoint of the birth canalThe position of your baby's head isn't knownYour baby's shoulders, arms, buttocks or feet are leading the way through the birth canalYour baby might not be able to fit through your pelvis due to his or her size or the size of your pelvis
Risks
A vacuum extraction poses a risk of injury for both mother and baby.
Possible risks to you include:
Pain in the perineum — the tissue between your vagina and your anus — after deliveryLower genital tract tears and woundsShort-term difficulty urinating or emptying the bladderShort-term or long-term urinary or fecal incontinence (involuntary urination or defecation)
Anemia — a condition in which you don't have enough healthy red blood cells to carry adequate oxygen to your tissues — due to blood loss during deliveryWeakening of the muscles and ligaments supporting your pelvic organs, causing pelvic organs to drop lower in the pelvis (pelvic organ prolapse)
While most of these risks are also associated with vaginal deliveries in general, they're more likely with a vacuum extraction.
If your health care provider does an episiotomy — an incision in the tissue between your vagina and your anus that can help ease the delivery of your baby — you're also at risk of postpartum bleeding and infection.
Possible risks to your baby include:
Scalp woundsA higher risk of getting the baby’s shoulder stuck after the head has been delivered, which could lead to an injury to the network of nerves that sends signals from the spine to the shoulder, arm and hand (brachial plexus), or a collarbone fractureSkull fractureBleeding within the skull
Serious infant injuries after a vacuum extraction are rare.
Manual Vacuum Aspiration
This type of procedure is best for women who are between five and twelve weeks pregnant.
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.
Manual vacuum aspiration usually takes between five and ten minutes. It can be done using local anesthetic and a nonsteroidal anti-inflammatory drug (NSAID), such as ibuprofen. The doctor will insert a speculum into the vagina and apply a numbing medication to the vagina and cervix. Then, the doctor will pass a thin tube through the cervix and into the uterus. A handheld syringe is attached and used to suction the tissue out of the uterus. As the uterine tissue is removed, the uterus will contract; most women feel cramping during the procedure. The cramps will lessen once the tube is removed. Some women also have nausea, sweating, or feel faint. You should rest after the procedure and resume regular activities the next day.
After the procedure you will experience irregular bleeding or spotting for the first two weeks. You may also have cramps similar to menstrual cramps, which may be present for several hours and possibly for a few days, as the uterus shrinks back to its normal size.
First-trimester surgical abortions are safe and effective and have few complications. Infection is less likely to develop after an aspiration procedure than any other type of surgical abortion. The total risk of complications udring and following a first trimester abortion is about 2-3%.
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 hollow 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.
