Obstetrics part II Vega EMS Flashcards
Name all stages of labor.
- Dilation
- Expulsion
- Placental delivery
How long does dilation last for a 1st time mother vs a women who has had a child before?
1st time mother: 8-10 hours
Para I+ mothers: 5-7 hours
At the end of stage 1 describe the frequency/duration/intensity of contractions.
contractions are at regular 3- to
4-minute intervals, last at least 60 seconds each, and feel very intense.
describe what marks the first stage of labor.
The first stage of labor is from the beginning of true labor (contractions) to complete cervical dilation and 100 percent effacement (cervix stretches and gets thinner). During this first and longest stage, the cervix becomes fully dilated at 10cm.
What are Braxton Hicks?
Contractions that feel like pregnancy contractions but do not indicate labor.
Define frequency, duration, and intensity.
The frequency or interval is the time between the start of contractions.
The duration describes how long the contraction lasted.
The intensity or strength of the contraction describes the amount of pain associated with the contractile force.
What occurs during stage two?
the infant moves through the
vagina and is born.
What is the frequency and duration of contractions during expulsion?
Contractions are less than 2 minutes apart and last 60 to 90 seconds each.
What does crowning/vertex presentation indicate?
The baby is coming, imminent birth.
How long does the expulsion phase last for 1st time mothers? (para 0 soon to be para 1)
50-60 minutes
How long does it take for the placenta to be delivered following birth?
5-20 minutes
signs that the delivery of the placenta is imminent are…?
There is a sudden increase in bleeding from the vagina.
The uterus becomes smaller in size.
The umbilical cord begins to lengthen.
The mother has an urge to push.
What should you NEVER do during placental delivery and why?
Pulling or tugging on the umbilical cord to deliver the placenta can cause the uterus to invert. If inverted, the uterus cannot contract and tone up effectively. The exposed uterine vessels continue to bleed and lead to serious hemorrhaging and hypovolemia.
Gestational age by landmark?
Fundus at the umbilicus – 20 weeks
Fundus at the xiphoid – 38 weeks
At 40 weeks, the fundus drops to below the xiphoid as the fetus moves into position for delivery
In which situations must you assist in the delivery of the baby?
There is no suitable transportation.
The hospital or physician cannot be reached due to bad
weather, a natural disaster, or catastrophe.
Delivery is imminent.
What questions should you ask to determine if delivery is imminent?
Has crowning occurred?
Are contractions less than 2 minutes apart?
Do they last 60-90 seconds?
Does the patient have the urge to defecate?
Does the patient has a strong urge to push?
What should you do to prevent an explosive delivery?
Apply gentle pressure to the head to prevent an explosive delivery. Avoid touching and exerting pressure on the baby’s face and on any soft spot
(fontanelle) on the head.
