CAUTION: Do not perform uterine aspiration/uterine evacuation until the size and position of the uterus
and cervix have been determined. Large fibroids or uterine anomalies may make it difficult to determine
the size of the uterus and hard to perform intrauterine procedures, including uterine aspiration/uterine
evacuation.
CAUTION: Use a cannula size appropriate to the size of the uterus and amount of cervical dilatation
present. Using a cannula that is too small may result in retained tissue or loss of suction. The range of
suggested cannula sizes relative to uterine size is as follows:
Warnings
As with any invasive procedure, there is a risk of infection to providers, patients, and support staff
through contact with contaminants. To minimize the risk, universal precautions must be observed at all
times. These include using appropriate barriers (such as gloves and masks), handling waste carefully and
taking precautions to prevent injuries.
Uterine aspiration/ uterine evacuation are procedures that involve minimal trauma to the uterus and
cervix. However, in a small percentage of cases, one or more of the following complications may
occur during or after procedures: uterine or cervical injury/perforation, pelvic infection, vagal reaction,
incomplete evacuation or acute hematometra. Some of these conditions can lead to secondary infertility,
other serious injury or death.
Precautions
Before performing uterine evacuation or endometrial biopsy, any serious medical conditions that
are present should be addressed immediately. These include: shock, hemorrhage, cervical or pelvic
infection, sepsis, perforation, or abdominal injury, as may occur with incomplete abortion or with
clandestine abortion. Uterine aspiration/uterine evacuation is often an important component of definitive
management in these cases and once the patient is stabilized, the procedure should not be delayed.
History of blood dyscrasia may be a factor in the woman's care. In cases where the woman has a history
of a blood-clotting disorder, Ipas cannulae and aspirators should be used only with extreme caution and
only in facilities where full emergency backup care is available.
