Insertion

Discussion

This is essential to ensure individuals make an informed choice about their contraception options and can give informed consent. These may be undertaken face-to-face, via telephone or virtual appointment, or by self-assessment and signposting to patient resources. Women can be encouraged to watch an eight minute information film produced by Lothian Sexual Health available at: https://www.lothiansexualhealth.scot/contraception/iud-ius/

When can LNG-IUD be inserted

LNG-IUD can be inserted at any time during the menstrual cycle providing that pregnancy can be reasonably excluded (see Box 1). Recommendations for starting or switching to IUC can be found in Table 1 and Table 2.

Box 1: Criteria for reasonably excluding pregnancy

Healthcare practitioners can be reasonably certain that an individual is not currently pregnant if any one or more of the following criteria are met and there are no symptoms or signs of pregnancy:

  • They have not had intercourse since the start of their last normal (natural) menstrual period, since childbirth, abortion, miscarriage, ectopic pregnancy or uterine evacuation for gestational trophoblastic disease
  • They have been correctly and consistently using a reliable method of contraception. (For the purposes of being reasonably certain that an individual is not currently pregnant, barrier methods of contraception can be considered reliable providing that they have been used consistently and correctly for every episode of intercourse).
  • They are within the first 5 days of the onset of a normal (natural) menstrual period.  They are less than 21 days postpartum (non-breastfeeding individuals).*
  • They are fully breastfeeding, amenorrhoeic and less than 6 months' postpartum.*
  • They are within the first 5 days after abortion, miscarriage, ectopic pregnancy or uterine evacuation for gestational trophoblastic disease.
  • They have not had intercourse for >21 days and have a negative high-sensitivity urine pregnancy test (able to detect human chorionic gonadotrophin (hCG) levels around 20 mlU/ml).

* See UKMEC 2016 and FSRH Guideline Contraception after Pregnancy for recommendations regarding use of combined hormonal contraception after childbirth.

Insertion Checklist

Intrauterine contraception pre-insertion checklist for the minimum criteria that should be met prior to insertion.   

The clinician inserting the intrauterine contraception (IUC) should ensure that (as a minimum) the following criteria are met prior to insertion:

  • Individual assessed as medical eligible
  • Checked there are no indications for IUC to be inserted in an alternative setting/service
  • Checked there are no allergies to IUC content or local anaesthetic
  • Checked it is a suitable time to insert and any requirement for additional contraception/follow up pregnancy testing
  • Considered and offered sexually transmitted infection (STI) testing and/or cervical screening as appropriate
  • Individual advised about:
    • Different IUC types available
    • Contraceptive effectiveness and time to effect (including need for additional contraception and/or follow up pregnancy test)
    • Duration of use (for contraception and other indications)
    • Potential bleeding patterns
    • Other potential side effects and risks
    • Insertion procedure and associated risks including: pain, infection, expulsion, perforation, failure, ectopic pregnancy, non-visible threads
    • Analgesia options and option to stop at any time during the procedure
    • Signs/symptoms that require review
    • How and when to check threads
    • Removal procedure
  • Individual given opportunity to ask questions and to reflect on new information and return for procedure or alternative at another time if they wish
  • Type of IUC device confirmed with patient and assistant
  • Expiry date on IUC and analgesia checked
  • Suitably trained assistant present
  • Appropriate equipment available (e.g. resuscitation equipment, appropriate examination couch/lighting, range of speculum sizes, analgesia options)

Safe LNG-IUD Insertion

Training: Clinicians offering LNG-IUD insertion should hold the CoSRH Letter of Competence in Intrauterine Techniques. Immediate postpartum intrauterine contraception (PPIUC) technique is different to standard LNG-IUD insertion and should only be performed by those who have trained in this technique.

Assistants and Chaperones: A chaperone should be offered for all intimate examinations. The chaperone’s role is to support the patient.  An appropriately trained assistant should be present during all cervical instrumentation procedures. The assistant can also fill the role of a chaperone if trained. The assistant should support the individual during the IUC procedure and monitor the patient for any signs of pain or distress.

Check the device has not expired: If an expired device is inadvertently inserted, inform the individual of the error and offer the option of retaining the device or having it removed and replaced. The expiry date relates to the microbiological sterility of the device. Risk of infection from loss of microbiological sterility could well be lower than the risk of infection if the device is replaced again when Intrauterine contraception. Manage the error according to local clinical governance policies.

Pain associated with LNG-IUD insertion

LNG-IUD insertions can cause mild-to-moderate pain or discomfort. Analgesia options should be discussed, offered and documented. NSAIDs such as ibuprofen can reduce pain after LNG-IUD insertion.

Emergency management for problems at IUD insertion

LNG-IUD insertion can trigger a vasovagal response. Drugs and equipment required for resuscitation must be available, accessible, clearly labelled, adequately maintained and their location known to all staff.  Follow locally agreed risk management policies for the treatment of emergencies.

Documentation

Clinicians inserting or removing IUD should document the procedure and consultation in line with local policy and protocol and notify (where applicable and with consent) other relevant healthcare providers (e.g. primary care) of the type of device, date of insertion and recommended duration of use.

Advice and Aftercare following Insertion

After IUD insertion, individuals should be given information on the device inserted, including the name of the device, its mode of action, duration of use and time to become effective. The manufacturer’s booklet/card will usually be given to the patient.

Where IUD has been inserted outside of product licence, information about how and when to perform a pregnancy test should be given.

Except for PPIUC, routine post-insertion check-ups with a clinician are not required. They should be advised to seek review at any time if they have concerns or cannot locate the coil threads. They should be given information on who to contact and how. Local pathways should be followed for PPIUC insertions and follow-up.

LNG-IUD users should feel for the threads within the first 4–6 weeks after insertion and then at regular intervals (e.g. monthly or after menses) and if they have any concerns suggestive of LNG-IUD displacement (e.g. change in bleeding pattern, new-onset pelvic pain).  Clinicians should explain how to feel for LNG-IUD threads and that users should seek review if threads are not palpable, thread length becomes shorter or longer, or the stem of the device is felt. The individual should be advised to abstain or use an alternative method of contraception until the LNG-IUD position is confirmed, and if there has been any recent, condomless sex they should seek advice as emergency contraception may be required.

Individuals should be advised to seek urgent review if they have:

  • Symptoms of pelvic infection (e.g. change in vaginal discharge, pelvic pain and intermenstrual/ postcoital bleeding)
  • Concerns regarding their bleeding pattern
  • A positive pregnancy test

Women can be encouraged to watch a 4 minute video produced by The West of Scotland Managed Clinical Network for Sexual Health for women who have recently had a LNG-IUD inserted which gives advice on what to expect, how to check for threads and when to seek advice.

Advice about use of menstrual cups, discs and tampons

There could be increased risk of expulsion associated with menstrual cup use. Users should be advised to follow the manufacturer’s instructions. Care should be taken not to dislodge the LNG-IUD by accidently pulling the LNG-IUD threads when removing the menstrual device.

There are not robust studies to inform effect of use of tampons on risk of expulsion.

There is no clear evidence of increased risk of infection associated with use of tampons, menstrual cups/discs or intercourse in the days or weeks after LNG-IUD insertion.

Advice for individuals requiring magnetic resonance imaging

Individuals should inform their MRI department so that local guidelines can be followed.

Mirena®, Levosert® and Benilexa® contain no metallic, magnetic or conductive material and are safe at any magnetic field strength. Jaydess® and Kyleena® have a silver ring on their stem which should not prevent basic MRI scanning, however the MRI department will make this decision.
