2P - Dysfunctional Labor Flashcards
A primi patient with a dilatation rate of 1cm/hr is experiencing what event?
Protracted labor
What mechanism of dystocia is affected by mechanical relationship between fetal head size and position and pelvic cavity?
fetoplevic proportion
What is a possible sign of fetopelvic disproportion?
Ineffective labor
A patient under labor experiences inadequate contractions, what is the primary traetment?
Oxytocin
What is the normal pressure for spontaneous contractions?
60 mmHg
*Montevideo units for normal contractions is 200 mmHg
What is the lower limit of contraction required to dilate the cervix?
15 mmHg
What type of uterine dysfunction is present if there is normal gradient pattern but the force is insufficient?
Hypotonic uterine dysfunction
What part of the uterus does the strongest force of contractions occur?
Fundus
What part if the pregnant uterus does the weakest force of contraction occur?
LUS
What type of uterine dysfunction is present if there is distortion in the contraction gradient and basal tone is eleveted?
Hypertonic uterine dysfunction or incoordinate uterine dysfunction
In incoordinate uterine dysfunction, where does the contraction start sometimes (not in the fundus)?
Midsegment
What is a common cause of incoordinate uterine dysfunction in primi patients?
cephalopelvic disproportion
If the parietal bone of the fetus is deflected laterally and you can feel the ears upon inspection, what is the asynclitism present?
Posterior asynclitism
What is the presentation of the fetus if the head is well flexed?
Suboccipitobregmatic
*shortest diameter - ideal for labor
What is the presentation of the fetus if the fetal head is is mento occipital position?
Face presentation
*longest diameter - not ideal
