|
Definition
32-40wks natural reaction to growing fetus and fluid and stretch on muscles (NO cervical dilation or effacement)
short, less intense than real, over lower, abd ad groin, hard feeling |

|
Term
changes to the uterus in pregnancy: muscle and fibers, cervix |
|
Definition
upper uterine active segment: stays muscular lower uterine passive segment: thins muscular and fibrous changes in isthmus
gradual elongation of muscle fibers as labor progresses fibers shorten to keep close to fetus forcing into canal
cervix remains closed until last 3-4 weeks. connect. tissue allows cervix to be taken into lower uterine segment and isthmus |

Definition
primary/involuntary uterine contraction secondary/voluntary uterine contraction (abd muscles) |
|
|
Term
how are utering contractions initiated |
|
Definition
one of two pacemakers located in each conual area of the uterine fundus. one predominates and initiates contraction in other
peach contraction is reached when all uterus fibers are stimulated (more in fundus, less in lower segment causing more pain in upper abd |

|
Term
what are the stages of labor |
|
Definition
1: interval between onset or labor and complete cervical dilatent 2: complete cervical dilation through the delivery of infant 3: from time of delivery of infant till delivery of placenta 4: immediate post partum period - 2h |
|
|
Term
|
Definition
usually effacement and dilation |
|
|
Term
|
Definition
usually begins with cervical dilation at 3-4cm dilated |
|
|
Term
explain the timing of dilation and station |
|
Definition
getting to 8-10cm dilation is slow then its fast to 14 cm
getting from station 0 to 1 is slow but when dilation is 10cm it takes off and becomes position |
|
|
Term
what do the numbers for station mean |
|
Definition
negative: more inside than ASIS 0: at ASIS positive: past ASIS |
|
|
Term
define mechanism of labor |
|
Definition
cardinal movements of labor, series of changes in attitude (tilt) and position of fetus for passage through pelvic cavity |
|
|
Term
what are the cardinal movements of the fetus in labor |
|
Definition
engagement: zero station descent: moves into birth canal flexion: puts chin down internal rotation/restitution: turns chin inward extension: extends chin back out external rotation: rotates chin other way expulsion: baby out |
