It is important to recognise the signs of labour so that you will know when you are experiencing the “real thing.”
If this is your first baby, you will most likely experience lightening (the descent of the baby’s head into your pelvis) sooner than women who have already had other children.
Typically, the signs of labour include
Tightening of your stomach, and
Cramps in your low back.
About two thirds of women experience these tightening before their waters break. About one third will notice fluid leaking out first.
If you are unsure about what is happening, don’t forget that the Mater Mothers’ Private Midwives are available 24 hours a day on 3163 7000 to answer any questions.
Types of Labour
Preterm labour is said to have occurred when you have strong contractions before 37 weeks of your pregnancy whereas the gestation period normally is 38 to 40 weeks. A baby, if born prematurely, will be at risk of complications such as immature lungs, respiratory distress, and problems in digestion as the organ systems would not have developed completely to support survival.
Dr Alexander will manage this situation with medications that stop labour or prevent infection. Also, medications that accelerate the baby's lung development may be given. You will be advised to take bed rest, usually lying on the left side.
Health problems of Preterm Labour
The longer the baby is in the mother's womb, the more likely he or she will be healthy. Early preterm babies may have respiratory and digestive problems. They are also at a higher risk of brain and related neurological complications.
Treatment for Preterm Labour
Treatment is provided in the form of medications. Corticosteroid injections are given to speed the development of your baby's lungs and other organs. A delivery date can be extended by 2 to 7 days with drugs called tocolytics that work to slow or stop contractions of the uterus. The extra time gained can be used to take corticosteroids or to get to a hospital specialising in preterm care for babies.
Women at Risk
Some women deliver an early premature baby for no apparent reason. However, certain factors may increase a woman's risk of early preterm birth. Some of them include lifestyle risks (for example: smoking, drinking), a woman pregnant with multiples, chronic illnesses and a short time between pregnancies.
Some women most often during their first pregnancy may go through a labour that lasts for too long. Prolonged labour may lead to infection in case the amniotic sac has ruptured. Anti-infective medications may be administered to prevent infection.
During labour, normally the baby moves to a head-down position with back of the head ready to enter the pelvis. Sometimes, the baby may present with buttocks or feet first towards the birth canal. This is called breech presentation. In some conditions, the placenta may block the cervix (placenta praevia) and cause abnormal presentation.
Abnormal presentation increases the risk of injuries to the uterus or birth canal as well as the foetus. Breech presentation may lead to a prolapsed umbilical cord that might cut off the blood supply to the foetus. Dr Alexander will check the presentation and position of the baby with physical examination and ultrasound scan. Assisted delivery methods may be adopted in such cases.
Premature Rupture of Membranes
Rupture of the membranes that surround the foetus in the uterus may occur prematurely leading to high risk of infection. In these cases, immediate delivery of the foetus will be done.
Umbilical Cord Prolapse
The umbilical cord, which transports oxygen and nutrition to the baby, may slip into the cervix before the baby during labour. The cord may be felt if it protrudes from the vagina. This is an emergency situation as the blood flow to the baby through the umbilical cord may get obstructed. Seek immediate attention of Dr Alexander.
Umbilical Cord Compression
The umbilical cord may get entangled and wrap around the baby several times during pregnancy, but sometimes during labour, the cord may get compressed leading to decreased blood flow to the foetus. This causes abrupt drop in the foetal heart rate. In cases where the foetal heart rate has worsened or there are signs of distress, Dr Alexander may consider a Caesarean section.
Amniotic Fluid Embolism
Amniotic fluid embolism occurs when a little amount of amniotic fluid from the amniotic sac gains entry into your bloodstream during a difficult labour. This fluid may travel up to the lungs and cause constriction of the lung arteries leading to a rapid heart rate, irregular heart rhythm, cardiac arrest and death. Blood clot formation throughout the body is a common complication and requires immediate care.
Child Birth Choice
Dr Alexander respects a woman’s right to choose the method of her delivery. If you wish to aim for a vaginal birth then he will support you fully in this choice. Similarly, if you choose to have an elective Caesarean Section he will also support you your choice.
Delivery Suits at Mater Mothers’ Hospital
Dr Alexander has chosen to deliver babies at the Mater Mothers’ Private Hospital because he feels that the Mater Mothers’ offer a safe environment for both Mother and Baby.
If all is going well then you should be able to experience labour the way you wish.
You can have a very “low-tech” birth if you wish, knowing that all the best equipment, services and staff are immediately available,
if required. Mater Mothers’ hospitals have operating theatres close by, Anaesthetists on standby and Paediatrician available.
Mater Mothers’ Hospital is considered a tertiary hospital and therefore has a Level 3 (the highest level) Intensive Care Nursery, if required.
One of the things you may be most concerned with is the amount of pain you may experience during labour.
Childbirth is different for all women, and no one can predict how much pain you will have.
During the labour process, your midwife or Dr Alexander will ask you if you need pain relief, and will help you decide what option is the best for you.
Your options may include
A local or intravenous analgesic (pain relieving drug),
An epidural (injection which blocks pain in the lower part of your body),
Spinal anaesthesia (used when the delivery will require forceps), or
A Pudendal block (numbs the vulva, vagina and anus during the second stage of labour and during delivery).
After your due date has Passed
Your due date is an estimate of the date of delivery and determined based on the date of your last period. Your physician uses this date to assess the progress of your pregnancy and baby's growth in the womb.
The due date may be confirmed or updated after ultrasound is performed between 18 and 20 weeks of pregnancy. Usually the due date is 40 weeks after the first day of your last period with most babies arriving between 37 and 41 weeks.
A post-term pregnancy is described as lasting 42 weeks or more.
Risks related to Post-Term Pregnancy
When a pregnancy exceeds 42 weeks, there is a small risk of the baby being stillborn.
The causes for such deaths have not been established with certainty but probable reasons include reduced efficiency of placenta (tissue that provides nourishment to the foetus) and a decrease in amniotic fluid levels. Other risks to the baby include meconium aspiration, neonatal acidemia, low Apgar scores, macrosomia (excess birth weight) which can lead to birth injury.
Tests associated with post-term pregnancies
The health of a baby not born by the due date is determined with the help of a few tests. The expecting mother herself can do certain tests, such as a ‘kick count’. This test is a record of how often the mother feels the baby moving.
Other tests such as electronic foetal monitoring involve measuring foetal heart rate and strength of uterine contractions by placing instruments under belts wrapped around the mother's abdomen.
Most hospitals suggest inducing labour (causing a pregnant woman's cervix to open and to prepare for vaginal birth) at maximum 40 weeks plus 10 days
Prostaglandins (naturally occurring fatty acids) and/or special devices are used to soften and dilate the cervix, following that rupturing the amniotic sac to release the fluid, and an intravenous Syntocinon hormone is then used to initiate and maintain the contractions of the uterus.
