4 stages of labor

A
  • first stage (dilation and effacement)
  • second stage (expulsion)
  • third stage (placental)
  • fourth stage (recovery)
105
Q

3 phases of first stage of labor

A
  • latent
  • active
  • transition
106
Q

Stages of labor - 1st stage - latent

A

from beginning of labor, 0 and up to 3 cm dilation

107
Q

what is the environment like during the latent phase?

A
  • Parents are happy, excited, wants to see baby
  • Walking in hall, sitting on birthing ball
  • Not much for nurses to do here
108
Q

Stages of labor - 1st stage - active

A

dilation from 4-7 cm, effacement complete, fetal descent into pelvis, internal rotation begins

109
Q

what is the environment like during the active phase?

A
  • Effacement may only get to 90%
  • Check mom more often
  • Nurse needs to check mom more frequently, start to get supplies ready, help mom to work with contractions at 5 cm
110
Q

Stages of labor - 1st stage - transition

A

dilation from 8-10 cm, intense contractions, urge to push

111
Q

what is the environment like during the transition phase?

A
  • Can be really hard, uncomfortable
  • Women want to give up
  • Has urge to push, should be dr driven
112
Q

Second Stage of labor

A
  • expulsion
  • Begins with complete dilation (10 cm) and full effacement and end with birth of baby
  • Vulva distends and crowning of head occurs
  • Woman puts forth a lot of effort to push baby out
  • BABY BORN! - Rush of positive emotion
113
Q

Third Stage of Labor

A
  • placental
  • After baby is born, immediately uterus shrinks (involution) placenta separates from uterine wall
  • Placenta can be expelled with either the fetal shiny side first (most common) or the maternal rough side
  • Uterus must remain contracted afterwards to compress vessels at implantation site to prevent hemorrhage
114
Q

how long does involution take?

A

10 minutes but could be as long as an hour

115
Q

For a C-section what happens to get the uterus to shrink?

A

  • Only acceptable with contraction
160
Q

FHR - Late Decelerations
