  2. 2. {2FC17CD2-D849-4252-9E3B-943E818AEC57} There are three stages of labour First stage Second stage Third stage
  3. 3. {15E92BA1-E5E0-4083-9EE1-E3F9B3840903} First stage of labour Latent phase Active phase Transition phase
  4. 4. {349E9A86-0B0D-4B0E-B0CB-8A766558F9BA} First stage: Latent Phase Not everyone will experience latent phase labour • Some changes can happen to the cervix during the • end of pregnancy in response to Braxton Hicks contractions Latent phase labour can be tiring and painful for • some women. During this phase the cervix is softening, effacing • and dilating to 2 to 3 cms Progress in this stage is often slow and may • continue over a period of days
  5. 5. {AB14A66A-41AF-4C34-A6BC-ABB4CEDF9712} First stage: Active phase During the active phase the cervix thins • and opens Thinning = Effacement • Opening = Dilation. • The cervix is usually fully effaced by 5cms • dilation Dilation is usually slower to 5cms, dilation • happens quicker after this When dilation gets to 7 to 8 cms the labour • becomes more intense
  6. 6. {A3ACDD9D-8827-4294-8457-1DB51CCD6C9F} First stage: Transition Around 7 to 8 cms dilation labour usually becomes • more intense Women often become restless and may become • anxious Reassurance that labour is progressing well and • that the end is in sight is helpful Women may start to feel some pressure and • occasional expulsive urges but these are controllable by breathing through contractions Women may need to use a birth pool, shower or • might want to use some Entenox at this time
  7. 7. {76E5240A-F58B-499B-81A7-B761E41A25C8} Second stage of labour The second stage of labour begins when the cervix • is fully open to 10 cms This is when the woman feels an overwhelming • urge to bear down As the foetus descends into the vagina there is • pressure on the anus which pouts The foetal head will become visible at the introitus, • initially appearing and disappearing between contractions Once the head is crowned it does not recede • between contractions The foetus moves through the birth canal and is • completely born

  9. 9. {52415AFC-9FDF-4C7F-875C-9E1A62D19685} Third stage of labour Once the baby is born the third stage of labour • commences After a pause the uterus begins to contract again • The fundus will be felt to rise and become firm just above • the umbilicus The contraction and retraction of the uterine muscle • reduces the size of the placental site and the placenta separates from the wall of the uterus A clot forms behind the placenta helping with separation • The placenta and membranes fall into the lower uterine • segment and the woman feels an urge to bear down The woman is supported in an upright position and the • placenta and membranes are born The third stage is complete once the placenta and • membranes are born and any bleeding is controlled.
