Copper-Bearing
Intrauterine Devices
Q.1. When can an IUD be inserted (interval)?
Recommendation: The IUD may be inserted at any
time during the menstrual cycle, at the user's convenience, when you can
be reasonably sure the woman is not pregnant (see How
to Be Reasonably Sure the Woman Is Not Pregnant). The IUD is
effective immediately.
Rationale: The IUD prevents pregnancy if inserted
before implantation (268).
Q.2. When can an IUD be inserted postpartum?
Recommendation: An IUD may be inserted:
- Immediately postplacental or during or immediately
after a cesarean section (special training
required).
- Prior to hospital discharge (up to 48 hours after
delivery) special training required).
Rationale: With the appropriate technique, IUDs
inserted immediately after placental delivery or
cesarean section can be safe and effective. Expulsion
rates for postpartum insertion vary greatly depending
on both the IUD type and provider's technique. Current
information indicates that the expulsion rates may be
higher from 10 minutes to 48 hours after delivery than
in the first 10-minute period. To minimize risk of
expulsion, only properly trained providers (according
to relevant national or institutional standards) should
insert IUDs postpartum. Use of an inserter for IUD
placement tends to reduce expulsion risk. Clients
should be counseled that expulsion rates are higher
postpartum than for interval insertion and should be
carefully trained to detect expulsions.
Recommendation: As early as 4 to 6 weeks postpartum, to
accommodate women who come to the clinic for routine
postpartum care and who request an IUD. Copper T IUDs
may be safely inserted at this time. For other types of IUDs, it may be prudent to wait until 6 weeks
postpartum.
Rationale: A copper T may be safely inserted at 4 or
more weeks postpartum. The withdrawal technique for
copper T insertion presumably helps minimize perforations when inserting IUDs at the routine 4- or 6-week
postpartum visit. Other IUDs that have a different profile or a push insertion technique might have different
perforation rates. Given the relative lack of information on other IUDs at 4 to 6 weeks postpartum, it is
prudent to wait until 6 weeks for the insertion of IUDs
other than copper Ts (37, 192, 203).
Recommendation: In breastfeeding women.
Rationale: It has been shown that IUDs can be safely
used in breastfeeding women (77).
Q.3. How long after a cesarean section should
a client have an IUD inserted?
Recommendation: A client may have an IUD placed at the
fundus during a cesarean section prior to closure of
the uterus, unless there are signs of infection.
Rationale: Immediate insertions during cesarean
sections by a properly trained provider have a lower
expulsion rate than vaginal insertions immediately
(within 10 minutes) after delivery. Studies also found
that women with IUDs inserted at the time of cesarean
section had longer continuation rates (317, 321).
Recommendation: If an IUD is not inserted at the time
of the cesarean section, it is recommended that the
IUD be inserted no earlier than 6 weeks after the
cesarean section.
Rationale: Delayed postpartum insertions should take
place no earlier than 6 weeks after cesarean section
because of the risk of uterine perforation. Clients
need careful assessment for presence of infection
before insertion even at this time (189).
Q.4. Can an IUD be inserted immediately post-abortion?
Recommendation: Yes, the IUD may be inserted immediately postabortion
(spontaneous or induced) if the uterus is not infected or during the first
7 days postabortion (or anytime you can be reasonably sure the woman is
not pregnant; see How to Be Reasonably Sure
the Woman Is Not Pregnant).
Rationale: With appropriate technique, IUDs can be
safely inserted postabortion (spontaneous or induced).
Expulsion rates vary greatly depending on both the
IUD type and provider. To minimize risk of expulsion,
only providers with proper training (according to
relevant national or institutional standards) and
experience should insert IUDs. Clients should be carefully trained to detect expulsions.
Fertility returns almost immediately postabortion
(spontaneous or induced): within 2 weeks for first-trimester abortion and within 4 weeks for
second-trimester abortion. Within 6 weeks of abortion, 75%
of women have ovulated (164).
Recommendation: IUDs should not be inserted in the
following situations:
- With confirmed or presumptive diagnosis of
infection (signs of unsafe or unclean induced
abortion, signs and symptoms of sepsis or infection, or inability to rule out infection), do not
insert an IUD until risk of infection has been
ruled out or infection has fully resolved
(approximately 3 months).
- With serious trauma to the genital tract (uterine
perforation, serious vaginal or cervical trauma,
chemical burns), do not insert an IUD until
trauma has healed.
- With hemorrhage and severe anemia, IUDs (inert or
copper-bearing) are not advised until hemorrhage
or severe anemia is resolved. However, progestin-releasing IUDs can be used with severe anemia
(they decrease menstrual blood loss).
- Postabortion IUD insertion after 16 weeks
gestation requires special training of the
provider for correct fundal placement. If this
is not possible, delay insertion for 6 weeks.
Rationale: After 16 weeks gestation, the uterine cavity
will be too enlarged for postabortion IUD placement
to be accomplished by routine IUD insertion techniques.
Only providers trained to do postpartum IUD insertion
should perform immediate postabortion IUD insertion
for postabortion clients after 16 weeks gestation (176, 221).
Q.5. What is an appropriate follow-up schedule
after IUD insertion?
Recommendation: There should be one follow-up visit
approximately 1 month after insertion; thereafter,
there is no need for a fixed follow-up schedule.
The client should be strongly encouraged to come to the
clinic any time she has questions or problems,
particularly if she has:
- Late period (possible pregnancy),
- Prolonged or excessive abnormal spotting or
bleeding,
- Abdominal pain or pain with intercourse,
- Infection exposure (such as gonorrhea), abnormal
vaginal discharge, or pelvic pain especially with
fever, or
- Strings missing or strings seem shorter or longer.
Visits are encouraged for other preventive reproductive
health care as available, including provision of
condoms, when appropriate.
Rationale: A follow-up visit at 3 to 6 weeks is prudent
since the peak incidence of pelvic inflammatory disease
(PID) post-IUD insertion is at 1 month. Thereafter,
there is no need for a fixed follow-up schedule. The
best quality of care is to focus clinic resources and
attention on those women who come back to the clinic
with complaints or problems (76, 131).
Q.6. Is there a need for a routine pre-exam (a separate visit)
before IUD insertion?
Recommendation: No. If at all possible, handle all
counseling and screening on the same day as the
insertion.
Rationale: There is no medical need for a pre-exam
(separate visit); it may be difficult for a woman to
make two visits, and she may be at risk of pregnancy
during this interval.
Q.7. Should young, nulliparous women receive IUDs?
Recommendation: An IUD may be provided to young,
nulliparous women only after careful and thorough
consideration. An IUD is only recommended for young,
nulliparous women if they are living in a stable,
mutually faithful relationship.
To receive IUDs, women should not be at increased risk
of STDs. Counseling should focus on the risk of STDs,
PID, and the possible risk of resulting infertility.
Rationale: Young women statistically have a higher risk
of PID. IUDs, in contrast to all other modern contraceptive methods, increase the risk of PID when a woman
is infected with an STD. PID is a major risk factor of
tubal infertility and ectopic pregnancies. Because
young women may have patterns of sexual activity that
lead to STD risk, the relative risk of PID in young IUD
users may be high. Additionally, nulliparous women
receiving IUDs may be at higher risk for expulsion.
The degree to which client values future fertility is
an important factor in the choice of a contraceptive
method. Studies have shown that the risk of PID and
subsequent tubal-factor infertility is directly proportional to the risk of exposure to sexually transmitted
disease. IUDs do not protect women against PID or
other STDs.
Nevertheless, women should be allowed to make their own
choice (7, 181, 215, 313).
Q.8. Are there medical reasons for removal of an IUD?
Recommendation: IUD removal is indicated if:
- The woman requests removal,
- The woman develops precautions/contraindications,
or
- The effective life of the IUD is reached.
Rationale: The removal and reinsertion of an IUD
exposes a woman to a small risk of introduction of
vaginal or endocervical canal microorganisms into the
upper genital tract. For this reason, long-acting IUDs
are preferred. The copper T 380A has been shown to be
effective for at least 10 years (76, 151, 218).
Q.9. Following removal of an IUD (for reasons of partial
expulsion without infection, or expiration of the IUD),
should one wait to insert another?
Recommendation: If the client wants to continue the
method, do not wait to reinsert a new IUD after old IUD
removal, provided pregnancy has been ruled out and no
new precautions/contraindications have developed.
Make sure removal of the first IUD is indicated (i.e.,
for reasons of partial expulsion without infection or
expiration of the IUD).
Rationale: Even with proper technique, the removal and
reinsertion of an IUD expose a woman to the risk of
introduction of vaginal and endocervical canal micro-organisms into the upper genital tract. Therefore,
removal and insertion at the same time avoid two
separate exposures (76).
In an interval between removal of one IUD and insertion
of another, the woman will not be protected against
pregnancy by the method of her choice.
Q.10. If a woman is at low risk of STDs based on history,
may IUDs be inserted without any lab tests if there
is no mucopurulent endocervical discharge or
clinically apparent PID or cervicitis?
Recommendation: Yes, if the woman has no current risk
factors for STDs (by history and on exam) and she has
no apparent clinical signs or symptoms of infection
(including normal bimanual exam).
If PID, mucopurulent endocervical discharge, cervicitis,
or clinically apparent vaginitis is present, do not
insert an IUD but treat for infection. Consider other
contraceptive methods, if an STD* is suspected.
* Not all clinically apparent vaginal infections are due
to STDs.
Rationale: Currently available lab tests may be
impractical and often unaffordable (even in the developed world) to rule out endocervical colonization by
infectious agents capable of ascending and causing PID.
Most chlamydia tests are only 80% to 90% sensitive,
tests for mycoplasma and ureaplasma are not routinely
available, and cervical gram stain is less sensitive
for gonorrhea. However, where gonorrhea culture and
chlamydia tests are affordable, negative test results
provide reassurance to corroborate the woman's
history (21, 154, 198).
Q.11. How much time should elapse between STD treatment
and insertion? What about previous STD incidence?
Recommendation: If the client will not be at high risk
of an STD in the future, treat the STD today and insert
the IUD when the infection is resolved (for acute PID,
wait 3 months).
If she remains at increased risk of PID, advise against
IUD use.
Rationale: PID may take several weeks to resolve
clinically, and, in the case of severe PID, waiting
several months in theory allows healthy tissues (free
of micro-abscesses) to form (267).
Women with prior PID are at increased risk of repeat
PID. A woman who has had an episode of upper reproductive tract infection may be at increased risk of repeat
episodes of nonsexually transmitted PID regardless of
IUD use. Theoretically, a previous episode of upper
reproductive tract infection may result in tubal damage
increasing susceptibility of the fallopian tubes to
opportunistic lower genital tract flora (139, 294).
Q.12. If a woman complains of heavier menses
or bleeding between menses, is there a
medical basis for removing the IUD?
Recommendation: Not necessarily. As in premethod choice
counseling, women should be informed that menses are
normally heavier with the IUD and intermenstrual bleeding may occur, especially in the first few months.
Inert IUDs should not be the first choice, for this
reason.
Give nutritional advice on the need to increase the
intake of iron-containing foods.
Rationale: In general, IUDs (especially inert IUDs)
commonly increase the amount of menstrual blood loss,
varying according to IUD type, particularly in the
first few months postinsertion (42).
Copper IUDs may increase normal menstrual blood loss by
50%, which may be clinically significant for women who
are already anemic. (Progestin-releasing IUDs decrease
menstrual blood loss; the more progestin an IUD releases, the more effectively it decreases menstrual
blood loss.) (69)
Recommendation: For mild to moderate bleeding and pain
in the first month postinsertion, with no evidence of
clinically apparent pelvic infection, and if reassurance is not sufficient but the woman wants to keep the
IUD, a short course of a nonsteroidal anti-inflammatory
agent other than aspirin (e.g., ibuprofen) may be given.
Rationale: Nonsteroidal anti-inflammatory drugs (e.g.,
ibuprofen*) decrease uterine bleeding and cramping (9).
* Nonsteroidal anti-inflammatory drugs (e.g. ibuprofen) should be
used instead of aspirin because of aspirin's stronger and longer-lasting inhibitory effects on platelet
aggregation (aspirin promotes bleeding) (5,83).
Recommendation: Bleeding generally decreases over time.
If bleeding is heavy or the woman is anemic, treatment
with oral iron can improve hemoglobin levels.
If bleeding or pain is severe, or the client wishes to
discontinue use, remove the IUD.
If suspected, abnormal conditions that cause prolonged
or heavy bleeding should be evaluated and treated as
appropriate.
If pelvic infection is diagnosed, remove the IUD and
treat with antibiotics. (In the case of mild uterine
tenderness without any other evidence of pelvic
infection, broad-spectrum antibiotics or chemotherapeutics may solve the problem; use clinical judgment
regarding whether or not to remove the IUD).
Q.13. Can IUDs be safely inserted by
trained nurses and midwives?
Recommendation: Yes, IUDs (including immediate
postpartum, postcesarean, and postabortion insertion)
can be safely inserted by nurses and midwives who
are appropriately trained according to relevant
national or institutional standards.
Rationale: Nurses and midwives have been shown to have
equal or superior competence in IUD insertion when
compared with doctors (73).
Q.14. Should IUDs be provided if infection-prevention
measures cannot be followed?
Recommendation: No. All sites inserting and/or removing
IUDs should follow basic infection prevention
measures, including:
- Appropriate handwashing by the provider and
careful preparation of the cervix,
- Sterile (or high-level disinfected) IUDs and
equipment,
- Correct decontamination of instruments, and
- Safe disposal of contaminated disposables.
Rationale: The potential for infection in IUD users is
increased in areas where genital tract infections (GTIs)
such as gonorrhea and chlamydia are prevalent. By
following recommended infection-prevention processes,
however, health workers can minimize the risk of post-IUD insertion infection to clients and the danger of
transmitting infections, even hepatitis B or AIDS, to
their clients, their co-workers, or themselves (272).
Sterilization is the safest and most effective method
for processing instruments that come in contact with
the bloodstream, tissue beneath the skin, or tissues
that are normally sterile. When sterilization equipment
is either not available or not suitable, high-level disinfection (HLD) is the only acceptable alternative. HLD
destroys all microorganisms, including viruses causing
hepatitis B and AIDS, but it does not reliably kill all
bacterial endospores. For example, in family planning
facilities, either sterilization or HLD is acceptable
for processing instruments and gloves used for pelvic
exams and IUD insertion and removal, since problems
with endospores (Clostridia species) have not been reported with IUD use. Regardless of the
method selected, however, HLD can only be effective when used (soiled)
instruments and gloves are first decontaminated,
thoroughly cleaned, and rinsed before disinfection (272).
Contaminated wastes may carry high loads of microorganisms that are potentially infectious to any persons who
contact or handle the waste. Incineration provides high
temperatures and destroys microorganisms; therefore it
is the best method for disposal of contaminated wastes.
Incineration also reduces the bulk size of wastes to be
buried. If incineration is not possible, all contaminated wastes must be buried to prevent scattering the
waste materials (272).
Q.15. Is it advisable to routinely give prophylactic
antibiotics for IUD insertion?
Recommendation: No, most authorities do not routinely
recommend it, because there is no clear evidence that
prophylactic antibiotics definitely prevent pelvic
inflammatory disease (PID) in IUD users and the studies
so far have found only a trivial impact on PID rates
due to prophylactic antibiotics. However, opinions
differ, and there are arguments to support both sides.
There is a theoretical rationale for the practice of
giving prophylactic antibiotics. PID rates in IUD users
are highest in the first few weeks, and antibiotics
could reduce those PID rates. While there is no statistically significant proof for reduction in PID rates,
one study found a lower rate of IUD-related unplanned
returns to the clinic.
Arguments against the use of prophylactic antibiotics
include the insignificant impact of antibiotics on
reducing the PID rates in IUD users demonstrated in
previous studies. Also, although the rate of PID in IUD
users is highest in the first few weeks after insertion,
due to the long duration of use of IUDs the greatest
numbers of PID cases will occur after the first few
weeks after insertion. In addition, there is some
concern about the programmatic feasibility and cost of
prophylactic antibiotics.
Good infection control procedures, proper assessment of
the client's risk for STDs, and proper insertions are
very important to keep the rate of PID low in IUD
clients.
Rationale: The scientific literature does not show any
large reduction in PID rates by giving prophylactic
antibiotics for IUD insertion (76, 160, 252, 287, 324).
However, in each of the studies, infection-prevention
procedures were followed, and the rates of PID were
very low. Also, the sample sizes in the studies were
small.
Although the differences were not statistically
significant, three studies all showed some reduction in
the PID rate in women given prophylactic antibiotics.
Sinei et al. found that the PID rates for the first
month after IUD insertion in women who were given
doxycycline was 1.3% compared with 1.9% in the women
who received a placebo. They also found that the women
who received a placebo returned to the clinic for IUD-related problems that were suggestive of subclinical
PID more often than the treated women (252).
Zorlu et al. found infection rates to be 2.1% and 2.9%
in doxycycline-treated and untreated women, respectively, within the first 3 months after IUD insertion (325).
Walsh et al. found that within the first 3 months after
IUD insertion, 3.6% of the doxycycline group had the
IUD removed for medical reasons compared with 4.5%
of the placebo group (287).
Q.16. If the cervix is red due to eversion of the
squamo-columnar junction (ectopy/ectropion),
may the IUD be inserted without further investigation?
Recommendation: Yes, the IUD may be inserted for
clients with cervical ectopy/ectropion, if not at risk
of STDs and the pelvic exam is normal (no cervicitis).
Rationale: Cervical ectropion (the presence on the
ectocervix of columnar epithelial cells from the endocervix) is a normal condition in adolescents and in
pregnancy, and is distinct from cervical infection (209).
IUD insertions and continued use of the IUD have no
relation to risk of cervical carcinoma (170).
Since chlamydia is an intracellular parasite of
columnar epithelial cells, women with ectropion may
be more likely to have positive chlamydia tests (113). |
