Flashcards in Dystocia Deck (32):
1

Definition of dystocia

a long, difficult, abnormal labor that prevents dilation, effacement, and decent

2

Definition of Eutocia

Normal birth

3

What are the 5 P's

Powers, Passage, Passenger, Positioning, Psychological

4

What is the primary power with dystocia?

Abnormal uterine contractions that prevent normal cervical dilation and effecement

5

What is the secondary power with dystocia?

Abnormal fetal descent through the pelvis

6

What is a precipitous power and what does it cause?

Labor that lasts less than 3 hours-- causes intense pain with contractions and no rest periods

7

What is hypertonic uterine dysfunction?

painful, frequent contractions that occur in the early phase (cervic <4cm), uncoordinated contractions and the uterus doesnt completely relax.

8

How do you treat hypertonic uterine dysfunction?

Rest and relax the mother and uterus, analgesics

9

What is hypotonic uterine dysfunction?

More common- after progressive labor, contractions stop, usually from malposition

10

How do you treat hypotonic uterine dysfunction?

Ultrasound to determine fetal position, FHR and pattern

11

Nursing diagnoses related to uterine dysfunction

Risk of injury due to prolonged labor, acute pain, anxiety

12

What are causes of precipitous labor?

Having babies before, large pelvis or small fetus, cocaine abuse

13

What are some complications of precipitous labor?

uterine rupture, laceration of birth canal, amniotic fluid embolism, fetal hypoxia, intracranial hemorrhage

14

What is pelvic dystocia?

Contractures of the pelvic diameters that reduce the capacity of the outlet

15

What causes pelvic dystocia?

congenital abnormalities, maternal malnutrition, neoplasms, spinal disorders

16

What is soft tissue dystocia?

An obstruction in birth passage from placenta previa, a full pladder, swollen cervic, etc.

17

What are some fetal causes of dystocia?

Abnormalities- hydrocephalus, tumors, neural tube defects, large weight (over 4000g), malposition, malpresentation, multiple fetuses

18

What is a malposition of a fetus?

Occipitoposterior

19

How do you correct occipitoposterior position?

Rotate the fetus or go for C section-- find cord with ultrasound before moving

20

Position of mother for good delivery

squatting or upright

21

Psychological responses related to dystocia

anxiety, apprehension, hormones and neurotransmitters

22

What is prolonged labor and risks associated with it?

Labor lasting longer than 24 hours with risks being fatigue, pain, overdistended uterus and hemmorrhage, and hypoxia to fetus

23

What is treatment methods of dystocia?

Position mother, monitor FHR, monitor maternal VS, maintain comfort and communication and support family

24

What is a type of chemical cervical ripening?

Postaglandin E- softens and thins the uterus (Misoprostol/Cytotex)

25

What is a type of mechanical cervical ripening device?

Mechanical dilators or a foley catheter

26

What is an amniotomy?

artificial ruptuer of membranes

27

When is oxytocin used?

To induce labor- also known as pitocin.

28

What does oxytocin do?

Stimulates uterine contractions

29

What are some complications with oxytocin?

water intoxication, premature seperation of placenta, rupture of uterus, post partum hemorrhage

30

What is a prolapsed umbilical cord and how does it happen?

When part of the cord lies below the presenting part of the fetus from either it being too long, breech presentation, transverse lie, or unengaged presenting part

31

What are indications for vacuum assistance during birth?

when the second stage of labor is prolonged, there is a non-reassuring heart rate, and it will relieve the woman's pushing

32

What are prerequisites for vacuum extraction?

vertex presentation, ruptured membranes
