Forces of Labour
The most common and favourable fetal presentation
What is Cephalic
The fetal lie that can not be born vaginally
What is Transverse?
The opening of the cervix from 0-10cm
What is Dilation?
Name three of the five signs of labour
What is:
Braxton Hicks contractions
Lightening
Increased vaginal mucous secretions - mucous plug
Cervical ripening and bloody show
Energy spurt
The largest part of the fetus to move through the pelvis
What is Fetal head?
The ideal pelvis shape for labour and birth
What is Gynecoid?
The most common and best fetal position
What is LOA - (Left Occiput Anterior)?
The thinning of the cervix from 0-100% or length of cervix in centimeters
What is Effacement?
Active labour dilation (in centimeters)
What is 4-7cms?
Membranous interspaces of the fetal head
What is sutures?
5 critical factors that determine the progress of labour
Hint - the 5 P's
What is:
Passageway
Passenger
Powers
Psyche
Position
The purpose of the 1st Leopold's Maneuver
What is distinguishes between a cephalic and breech presentation?
Name 2 of the 5 methods to assess uterine activity
What is:
Birthing person perception
Palpation
External (Tocodynamometer)
Intrauterine pressure catheter (IUPC)
This happens in the third stage of labour
What is Birth to delivery of the placenta?
The presentation that is more common in preterm births
What is Breech?
The critical factor that plays a great role in the progress of labour
What is Psyche
The fetal position that causes back pain and a longer labour
What is LOP (Left Occiput Posterior)?
Two considerations when assessing uterine contractions
Double your points - define these considerations
Frequency - Number of contractions in a 10 minute window, averaged over 30 mins.
Duration -Time from the beginning to the end of the contraction in seconds.
Intensity- Assessment of contraction strength described as mild, moderate, or strong by fundal palpation or by mmHg when using IUPC
Resting tone - Described as soft or firm between contractions by palpation when using IA or external EFM or by mmHg when using IUPC
The average duration of the first stage of labour for nullipara's (in hours)
What is 8-10 hours?
Assessment of this is essential in order to identify abnormal contraction patterns that could adversely affect fetal oxygenation
What is Uterine activity
The "Secondary" action of "Powers" critical factor
What is pushing
Name 3 of the seven cardinal movements
- Engagement
-Ascyclitisim
-Descent
-Flexion
-Internal rotation
-Extension
-Restitution and external rotation
-Birth by expulsion
>5 contractions in 10 minutes, averaged over 30 minutes
What is Tachysystole?
Cervical dilation greater than or equal to this many centimeter per hour is considered normal in low-risk nulliparous birthing people
What is 0.5cm/hr?
Two of the three reasons uterine contractions are painful
What is:
Decreased oxygen to muscle
Pressure and stretching of nerves and tissues
Usually felt in suprapubic area
