Feel confident 

with your labour induction

Dilapan-S®  Gentle. Predictable.

What is labour induction?

In most pregnancies, labour will start naturally between 37 and 42 weeks of pregnancy. Under normal circumstances, your cervix softens and starts to open, you’ll get contractions or your water may break.

Nevertheless, in some situations your labour may need to be started artificially. This is called induced labour, or labour induction. It may involve mechanically softening and opening your cervix, breaking your waters, or using medicine to start off your contractions.

Do not worry, it is nothing so uncommon! Nowadays, approximately 25% of all pregnancies need to be induced.

Why might I need to be induced?

You will be offered induced labour if your clinicians decide that you and your baby might benefit from delivering sooner rather than later. Labour induction can also be performed for matters of convenience or preference, in such case it’s called an elective labour induction.

The most common reasons for labour induction

    Your pregnancy is prolonged beyond 42 weeks with possible risk to the baby from a gradual decrease in the supply of nutrients from the placenta.
    If your water has broken and contractions have not started on their own within 24 hours, you and your baby may be at an increased risk of infection.
    The estimated weight of your baby is less than 90 percent of what is expected for the gestational age.
    There's not enough water surrounding your baby.
    You have diabetes that develops during pregnancy.
    High blood pressure can cause complications during pregnancy but if controlled well, induction of labour is not always necessary. You can hear your clinician saying you have a high blood pressure problem called preeclampsia, which is a serious disorder, characterized by high blood pressure and other signs that a women’s organ systems are not working normally. Preeclampsia is often a cause for induction of labour.
    You have a medical condition such as kidney disease or obesity.

The hospital recommendations will be followed by your clinician to determine if and when the elective labour induction is okay for you and your baby.

What is Dilapan-S®

Dilapan-S in the hands

Dilapan-S® is an osmotic dilator, produced from a patented hydrogel, that absorbs fluid from your cervical canal and therefore increases in volume. This helps your cervix to soften, open and get ready for your labour in a gentle and natural way.

The solely mechanical dilation allows safe, predictable and efficient preparation of your cervix for the labour.

Dilapan-S® does not contain any pharmacological substances. Hence its use is free of artificial uterine contractions, that are not suitable at this stage of labour.

Dilapan-S® rods are supplied sterile. The device is manufactured in an ISO 13485 Certified facility and is CE Certified under the Medical Device Directive (93/42/EEC). Approved by FDA for sale in the United States.

How does DILAPAN-S® work?

Dilapan-S® is a synthetic rod made of patented hydrogel,  which absorbs the fluid from your cervical tissue.

The thin 4 mm rod can expand up to 15 mm over a 12–24 hours period. This allows it to dilate and soften the cervix gradually. Usually a set of 3–5 rods is used to ripen your cervix sufficiently and make you ready for your labour.

Understanding cervical dilation / induction of labour

Why can’t I just be started on an oxytocin infusion to get my contractions going?

Your physician can’t start you on an oxytocin infusion (the drug, which promotes your contractions) until your water has broken. Hopefully, following the insertion of DILAPAN–S your water will break either on its own or your physician or midwife will break it. The membranes are diffi cult to break artifi cially until your cervix is 2–3 cm dilated. DILAPAN–S is used to increase the dilation and prepare your cervix for a successful induction.

Can I have DILAPAN–S if I have any systemic disease or I have had a previous Caesarean section?

Yes. Having no pharmacological content, DILAPAN–S has minimal limitations related to medical conditions. It can be used in pre-term, term, and post-term pregnancies, as well as in mothers with systemic disease such as hypertension, diabetes, etc. It is also suitable for mothers with previous Caesarean section. Cervical ripening is usually gentle and gradual and will not cause your womb to over-contract or cause your baby to get distressed. DILAPAN–S should not be used only if you currently have any clinically apparent genital tract infection.

How will DILAPAN–S be inserted? Is it painful?

DILAPAN–S is inserted into your cervix during a vaginal examination. It will take approximately 5–10 minutes. Your legs will be raised on the bed and a vaginal mirror will be inserted by the clinician. The DILAPAN–S rods will then be inserted into your cervix. The procedure can be a bit uncomfortable, but generally it is well tolerated by most patients. Shortly before and after the procedure, your baby’s heartbeat is usually monitored using a cardiotocography (this is a common practice regardless of the method being used). Some minor bleeding might occur during or after insertion; this is common and should not be a concern.

When will DILAPAN–S be removed and what occurs after the removal?

The DILAPAN–S rods should be removed within 12–24 hours of insertion. Your clinician will perform a vaginal examination, remove the DILAPAN–S and determine if your cervix has suffi ciently dilated. As long as your cervix has suffi ciently dilated and is ready for induction, common induction protocol should be used. Usually the membranes are broken. After that, your clinician will wait for 1–2 hours to see if contractions start naturally on their own. If contractions have not started after this period, an oxytocin infusion may be started at this stage.
