Flashcards in Abnormal Labour Deck (20):
List factors that determine labour as abnormal
Intervention required (operative)
What causes transient hypoxia in a baby during labour?
Uterine contractions (interrupt placental blood supply)
List options for providing analgesia during labour
Support, massage/relaxation techniques
Entonox (laughing gas)
Epidural anaesthesia impairs uterine activity. True/False?
May inhibit progress during stage 2 labour, however
What vertebral level is the epidural anaesthetic injected into?
List potential complications of epidural anaesthesia
What counts as delay in stage 1 labour?
Nulliparous woman: less than 2cm dilation in 4 hours
Parous woman: less than 2cm dilation in 4 hours OR slowing in progress
What are the 3 P's that affect progression of labour?
Power (inadequate contractions)
Passage (shape/state of pelvis)
Passenger (big baby, malposition)
Going down the pelvis, the transverse diameter increases/decreases and the anteroposterior diameter increases/decreases
Going down the pelvis, the transverse diameter decreases and the anteroposterior diameter increases
What is a partogram?
Graphical representation of the progression of labour
What is assessed on a partogram?
Foetal heart rate
Maternal vital signs
How often is the foetal heart auscultated during labour?
Stage 1: during + after a contraction/every 15 mins
Stage 2: every 5-10 mins
Meconium (foetal stool) can be a sign of what?
What is a CTG used for?
Assess foetal heart
You can only assess frequency of contractions on a CTG, not strength. True/False?
What is a normal foetal heart rate?
What 4 features are assessed on a CTG?
What is the mnemonic for remembering this?
Heart rate, variability, accelerations, decelerations
Outline management of foetal distress in labour
Change maternal position
Foetal blood sampling (hypoxia)
What is a normal pH to obtain upon foetal blood sampling?
pH greater than 7.25
