  • LMP :last menstrual period

  • EDC: expected date of confinememt


The four factors for labor

The four factors for labor

  • Force (contraction)

  • birth canal (bony canal)

  • fetus (lie,position ,presentation,weight)

  • psychical-factors


The contractions

The contractions

Bony pelvis

Bony pelvis

  • The planes of pelvis

  • inlet plane (promontory)

  • mid plane of pelvis(ischial spines)

  • outlet plane(two intersecting triangles)


Mechanism of labor

Mechanism of labor

  • Engagement*

  • Flexion

  • Decent

  • Internal rotation

  • Extension

  • External rotation


Symptoms and signs of the onset of the labor

Symptoms and signs of the onset of the labor

  • Painful uterine contraction

  • a show

  • effacement and dilation of the cervix

  • rupture of membranes


Normal labor and deliveryafe

  • The mucus plug is expelled from the cervix

  • mixing with a little blood

    the rupture of the membranes

  • at any time during labor

    effacement and dilation of the cervix

  • to be short,taken up,dilated

  • dilation of cervix and frequency

  • severity of uterus contractions(auscultation or electronic monitoring)


The second stage

The second stage

  • :--- < 2 hour

  • fetal heart rate

  • maternal conditions:

  • pulse, blood pressure, respiratory rate ,

  • temperature, urine output, fluid intake…

  • evaluation of progress of labor

  • cervical dilation, station,position of the

  • presenting part, status of membranes,

  • meconium, blood


Normal labor and deliveryafe

  • Pushing:

  • with the onset of each contraction, the mother is encouraged to inhale,hold her breath, and push

  • increase in intra-abdominal pressure

  • aiding in fetal descent through the birth cacal.


Normal labor and deliveryafe

  • Head visible on vulval gapping*

  • Crowning of head*

  • Laceration or Episiotomy

  • Delivery of fetus

  • Deal with umbilical cord


The third stage

the third stage:

  • waiting for up to 30 min’

  • the uterus decreases in size

  • delivery of placenta(spontaneously, manually

  • inspection of the birth canal

  • evaluated for lacerations


The fourth stage

“The fourth stage”
