What are the common signs of labour (baby delivery) in Singapore?

  • Bloody mucus plug “show”
    This is a thick mucus plug tinged with blood that can be passed out in the days or hours before labour starts.
  • Contractions
    Contractions are painful tightenings of your uterus that last for 30 seconds or longer and come at regular intervals every 10 minutes or so, which goes on for several hours. They are different from Braxton-Hicks, which are transient, uncomfortable, but not painful.
  • Leaking liquor
    This refers to the breaking of your water bag. Not everyone will experience a “pop”, but you will feel fluid continuously trickling out of your vagina which is beyond your control (unlike urine). You may wet your underwear or clothes. 

What are the stages of labour?

The first stage of labour can be divided into the latent phase and active phase.

The latent phase involves irregular and not always painful contractions. You may or may not have “show” or experience leaking liquor at this point – or these may not happen till the active phase. The cervix begins to change from being closed and long. This process takes a variable amount of time and often is longer in first time mothers. You can continue to eat and drink normally during this time.

The active phase involves regular, painful contractions which allows the cervix (neck of the womb) to dilate. The cervix progressively dilates and shortens to reach 10cm (full dilation) during this stage of labour. This is usually the point where most women will require pain relief. As a rough guideline, once you hit about 3-4cm, you will take about 1hr for every 1cm dilation. Your baby’s heartbeat will be monitored through an electronic monitor from this point. Your gynaecologist may need to break your waters artificially and/or start you on an oxytocin drip to get your contractions regular and stronger.

The second stage of labour begins from when full dilation is achieved until delivery of the baby. There will be an intense feeling of needing to pass motion (because of compression from baby’s head) if you are not on epidural. During this process, the baby’s head descends through the birth canal and is delivered with the mother’s pushing. An episiotomy (vaginal cut) is usually performed for first time mothers. It generally takes about 1 hour for baby’s head to descend into the pelvis and another hour to push the baby out. The third stage of labour starts after the baby is delivered and ends when the placenta is out. You will be given an intramuscular injection to help your uterus contract.Labor is considered term if it occurs between 37 to 42 weeks. It is considered preterm if it occurs before 37 weeks. If you go 1 week beyond your due date (which is 40 weeks) in an uncomplicated pregnancy, you will generally be offered induction of labour.

What are some options to deal with labour pain in Singapore?

There are 4 main options. These are:

Natural methods

These include hypnosis, hydrotherapy, local warm or cold applications, transcutaneous electrical nerve stimulation (TENS). They vary in effectiveness and may be useful for short labours.

Entonox “laughing gas”

A short-acting gas mixture of nitrous oxide and oxygen is breathed in through a mask as soon as a contraction begins. There is no need to continue breathing in the laughing gas when the contraction goes away. Laughing gas does not remove the pain; just alters its perception. The effectiveness of entonox in relieving labour pains is variable. Side effects include light-headedness and nausea.

Opioid Injections

Pethidine is an opioid that is injected into the thigh, takes 15-30 minutes to take effect and lasts for 2-3 hours. However, it should not be given within 4 hours of the anticipated delivery, as it can cause drowsiness and breathing problems in the newborn. Side effects include drowsiness, nausea and vomiting in the mother.

Epidural

Epidural is the most reliable and effective way to relieve labour pain. Local anaesthetic is injected through a small tube inserted into the back. This is best done at the start of active labour by an anaesthetist. Although epidural can almost eliminate labour pains till full dilation, most patients will feel some pain and pressure as the baby’s head descends and during pushing. In mothers who do not feel any sensation at all during pushing, the risk of an assisted vaginal delivery (e.g. vacuum or forceps) is slightly increased.

When will I need a Caesarean Section?

3 in 10 mothers undergo caesarean sections, or C-sections. This means delivering their babies through a cut in their abdomen and uterus under either a half-body anaesthesia (regional) or full-body anaesthesia (general anaesthesia). A urine catheter will be inserted into your bladder to drain your urine temporarily until the anaesthesia wears off. Reasons for needing a caesarean section may include:

Maternal reasons

  • Medical conditions e.g. severe pre-eclampsia, unstable heart condition, active genital herpes etc
  • History of previous caesarean sections
  • Prolonged first stage of labour with poor progress (cervical dilation is stuck)

Foetal reasons

  • Baby in breech (head up) or transverse (sideways) presentation 
  • Placenta is low-lying or previa (covering the cervical opening)
  • Baby too large (macrosomia) or head disproportionate to mother’s pelvis (cephalopelvic disproportion)
  • Severely small baby (foetal growth restriction): unable to tolerate labour stress 
  • Foetal distress: dropping baby’s heartbeat

What should I expect after a caesarean section?

If you had a half-body anaesthesia, you will be able to hold your baby, start skin-to-skin and breastfeeding. If you had general anaesthesia, you will need to wait until you are fully alert before doing so. You should also be able to start drinking and eating slowly a few hours after the procedure. You may start to feel some pain around your wound after the anaesthetic effects wear off so you should take your painkillers as prescribed. Breastfeeding help will be available via your nurses and lactation consultant.

On the first day after your caesarean section, you will be asked to sit up and move around your room with an abdominal binder around your wound for support. You should keep your legs moving even in bed, as pregnant women have an increased risk of forming blood clots in their legs (deep vein thrombosis) – this is higher after surgery. Your urine catheter will be removed and you should be able to pass urine by yourself.

What are the risks of a caesarean section?

Caesarean sections are commonly done and is generally a safe procedure. The risks of an emergency caesarean is about 4 times that of an elective caesarean. Some of the risks may include:

Common (affecting 1-5% of patients):

  • Infection
  • Bleeding: may require blood transfusion and in rare cases, hysterectomy (removal of uterus if bleeding is life-threatening)
  • Cuts on baby’s face/buttock (1.5%)
  • Breathing problems for baby (1.5%)

Uncommon (affecting 0.1-1% of patients):

  • Increased risk of uterine scar rupture (previous caesarean scar giving way) during labour in subsequent pregnancies 
  • Increased risk of placenta sticking to the scar in subsequent pregnancies, causing bleeding problems and possibly requiring hysterectomy 

Rare (affecting <0.1% of patients):

  • Deep venous thrombosis (blood clot in the leg) or pulmonary embolism (blood clot in the lung)
  • Injury to surrounding organs: bladder, ureter 
  • Maternal death: the risk is approximately 82 in 1 000 000

Do I need an episiotomy?

A mediolateral episiotomy is a cut made by sterile scissors in your vagina when your baby’s head is about to be delivered. This cut is made downwards and diagonally away from your anus. This has a few aims:

  • allows more space for your baby to come through
  • reduces your risk of having multiple vaginal tears 
  • reduces your risk of having a third or fourth degree tear (tears that go into your anus and involve your anal muscles)

If your baby is very large, or your pushing is very fast and strong, or you have a short perineum (distance of your tissue between your vagina and anus), an episiotomy may not be able to protect you completely from having multiple tears or a third/fourth degree tear (although it does reduce your risks of having these). 

Other instances that episiotomy is required include:

  • needing to deliver your baby fast (heart beat dropping etc)
  • needing an assisted vaginal birth (e.g. vacuum or forceps)
  • big baby 
  • short perineum
  • previous third or fourth degree tears

Is postpartum depression post-labour normal?

Feelings of sadness, being upset, anxious or even anger start 2-3 days after childbirth. These are baby blues, can come and go, and usually get better within 1-2 weeks with help and support from your loved ones.

However, unlike baby blues, the feelings of postpartum depression are a lot more intense and persistent. You may feel helpless, hopeless, constantly on edge and despair of ever being able to handle yourself, much less your baby. These feelings may start 1-3 weeks after childbirth or even after that. This is a medical condition that needs help. It does not mean that you are a useless mother! You should speak to your partner and gynaecologist about this as good treatment options are available.

Psychological therapy allows you to talk through your feelings with a trained specialist and develop coping strategies. Cognitive behavioural therapy, where you change your ways of thinking and behaviour, has been shown to be helpful. You can do therapy one-on-one, or involve your partner/family members so that they have a better understanding of what you are going through. Support groups can be a great source of comfort.

Antidepressants can also be helpful in managing your emotions although it may take a couple of weeks to take effect. Breastfeeding is still possible when you are on anti-depressants as the level found in breast milk is low – speak to your doctor about this.
