Heavy bleeding after birth (postpartum haemorrhage)

Q 1. What bleeding can I expect after my baby is born?

A. It is normal to bleed from your vagina after you have a baby. This blood mainly comes from the area in your womb (uterus) where the placenta was attached, but it may also come from any cuts and tears caused during the birth.

Bleeding is usually heaviest just after birth and gradually becomes less over the next few hours. The bleeding will reduce further over the next few days. The colour of the blood should change from bright red to brown over a few weeks. This vaginal bleeding is called the lochia and it will usually have stopped by the time your baby is 12 weeks old.

Sometimes bleeding during or after birth is heavier than normal.

Q 2. What is a postpartum haemorrhage (PPH)?

A. Postpartum haemorrhage (PPH) is heavy bleeding after birth. PPH can be primary or secondary:

• Primary PPH is when you lose 500 ml (a pint) or more of blood within the first 24 hours after the birth of your baby. Primary PPH can be minor, where you lose 500–1000 ml (one or two pints), or major, where you lose more than 1000 ml (more than two pints).
• Secondary PPH occurs when you have abnormal or heavy vaginal bleeding between 24 hours and 12 weeks after the birth.

Q 3. How could a PPH affect me?

A. If you lose a lot of blood, it can make you anaemic and worsen the normal tiredness that all women feel after having a baby.

If heavy bleeding does occur, it is important that it is treated very quickly so that a minor haemorrhage doesn’t become a major haemorrhage, which can be life-threatening.

Q 4. Who is at risk of primary PPH?

A. Most women who have a primary PPH have no identifiable risk factors

Risk factors for primary PPH

Before the birth:

• Known placenta praevia – when the placenta is located lower down near the neck of the womb
• Suspected or proven placental abruption – when the placenta separates from the womb early
• Carrying twins or triplets
• Pre-eclampsia and/or high blood pressure
• Having had a PPH in a previous pregnancy
• Having a BMI (body mass index) of more than 35
• Anaemia
• Fibroids
  • Blood clotting problems
  • Taking blood-thinning medication
• In labour:
  • Delivery by caesarean section
  • Induction of labour
  • Delay in delivery of your placenta (retained afterbirth)
  • Perineal tear or episiotomy (a surgical cut to help delivery)
  • Forceps or ventouse delivery
  • Having a long labour (more than 12 hours)
  • Having a large baby (more than 4 kg or 9 lb)
  • Having your first baby if you are more than 40 years old
  • Having a raised temperature (fever) during labour
  • Needing a general anaesthetic during delivery

  Often there is very little that you can do about these factors.

  However, in some cases, steps can be taken to reduce the risk of having a PPH and also to reduce the likelihood of needing a blood transfusion:

  • If you are anaemic during pregnancy, taking iron supplements may reduce the likelihood of needing a blood transfusion. Some women may also be offered iron supplements if they are at risk of If you are very anaemic during pregnancy or find it difficult to take tablets, iron can be given intravenously (through a drip).
  • If you have had a previous caesarean section and the placenta attaches itself to the area of the previous scar, leading to placenta accreta/percreta (also known as morbidly adherent placenta), it may not come away easily after birth. This condition is uncommon but it can cause major haemorrhage. If this is suspected on your ultrasound scan, you may be offered additional scans.

  Treating major haemorrhage may include having a blood transfusion.

  Q 5. What can be done during birth to reduce the chance of a primary PPH?

  A. If you have a vaginal birth, you should be offered an injection into your thigh just as the baby is born to help reduce blood loss. This injection helps the placenta to come away from the womb. Once your placenta has been delivered, you will be examined for any tears. If the tears are bleeding heavily, they will be stitched to reduce any further blood loss.
  If you have a caesarean section, the same injection will be given and your placenta will be removed through the caesarean incision.If you are known to be at high risk for PPH, you may be given additional medications to help reduce the amount you may bleed.

  Q 6. What happens if I have a primary PPH?

  A. You may feel dizzy, light-headed, faint or nauseous.
  In the majority of cases, heavy bleeding will settle with the simple measures listed below.

  The doctor may:

• Massage your womb through your abdomen, and sometimes vaginally, to encourage it to contract
• Give a second injection into your thigh (or a first, if you did not have one at the time of the birth) to help your womb contract
• Put a catheter (tube) into your bladder to empty it as this may help the womb contract
• Put a drip into your arm to give you some warm fluids after taking some blood for testing
• Check to make sure that all of the placenta has come out. If there are any missing pieces still inside your womb, you may have to have them removed; this is usually done in an operating theatre under anaesthetic
• Examine you to see whether any stitches are required.
• Your blood pressure, temperature and pulse will be checked regularly and you will stay on the labour ward until the bleeding has settled. You can breastfeed if you wish.

Q 7. What happens if I continue to bleed very heavily?

A. If heavy bleeding continues and you have lost more than 1000 ml of blood, you will need multi-disciplinary care.

Medications may be given as an injection or via the back passage to help stop the bleeding. You will be given oxygen via a facemask and a second drip for extra intravenous fluids. You may be given a blood transfusion or medication to help your blood to clot.

If the bleeding continues, you may be taken to the operating theatre to find the cause of the haemorrhage. You will need an anaesthetic for this. Your partner will be kept informed about how you are and what is happening, and your baby will be cared for.

There are several procedures your doctors might use to control the bleeding:

• A ‘balloon’ may be inserted into your womb to put pressure on the bleeding blood vessels. This is usually removed the following day.
• An abdominal operation (laparotomy) may be performed to stop the bleeding.
• Very occasionally, a hysterectomy (removal of the womb) is necessary to control the heavy bleeding.
• In some situations, a procedure called uterine artery embolisation may be performed to help stop the bleeding. This procedure is done by a specially trained radiologist (X-ray doctor). It involves injecting small particles via a thin tube (catheter) under X-ray guidance to block the blood supply to the womb.

Once your bleeding is under control, you will either be transferred back to the labour ward or you may be transferred to an intensive care or high-dependency unit. You will be monitored closely until you are well enough to go to the postnatal ward.

Q 8. How will I feel afterwards?

A. You may need a longer hospital stay. If tests show that you are very anaemic or if you are feeling faint, dizzy or light-headed, you may be offered a blood transfusion.

You can still breastfeed after a PPH and you can ask your healthcare team about extra support.

When you go home you may still be tired and anaemic, and you may need treatment with iron. It may take a few weeks before you make a full recovery. You can help improve your iron levels by taking iron tablets regularly and by eating a healthy diet including foods rich in iron (such as meat, pulses, eggs and leafy green vegetables).

You may be offered daily blood-thinning injections (heparin) and compression stockings to wear for 10 days after the birth of your baby. This is because after a PPH you are at increased risk of developing blood clots in your legs or lungs. Your doctor or nurse will teach you and your birth partner how to do the injections yourself.

Q 9. What about future births?

A. If you have had a birth that was complicated by a primary PPH, there is an increased risk of PPH in future births. During pregnancy you may be advised to take iron supplements to reduce the chance of becoming anaemic. You should discuss your birth options with your healthcare team.

When you are in the hospital and in labour, you may have blood tests and a drip may be inserted into your arm so that fluids and medication can be given if needed. You will be offered medication to help the placenta come away and reduce the risk of a PPH.

Q 10. What happens if I have a secondary PPH?

A. Secondary PPH is often associated with infection in the womb. Occasionally it may be associated with some placental tissue remaining in your womb. It usually occurs after you have left hospital.

You should contact your doctor if your bleeding is getting heavier, if your lochia has an offensive smell or if you feel unwell. You may be given a course of antibiotics to treat an infection.

If the bleeding is heavy or continues, you may need to go to hospital for further tests. You may need antibiotics which will be given through a drip. Less commonly, you may need an operation to remove any small pieces of remaining placenta from your womb. You may need to stay in hospital for a few days.

Your baby can usually stay with you if you wish, and you can continue to breastfeed.

Q 10. What are the Key points?

A. The key points are:

• It is normal to bleed after you have a baby. Initially, bleeding can be quite heavy but it will reduce with time. You may continue to bleed for several weeks after delivery.
• Women at high risk of haemorrhage will be advised to have their baby in a hospital setting.
• Sometimes bleeding is much heavier than normal and this is called postpartum haemorrhage (PPH). It is important to remember that the majority of women will not experience a haemorrhage after giving birth. If bleeding is very heavy, it is important to act quickly.
• In the majority of cases, heavy bleeding will settle with simple measures.
