Rupture of the amniotic sac before the onset of labor .
|
What is a marginal placenta implantation?
The lower border of the placenta is more than 3 cms from the internal cervical os.
|
What does the turtle sign indicate?
After the head if delivered, it is retracted into the perineum, like a turtle retracting into its' shell indicating a possible shouilder dystocia.
|
|
What are associated factors of preterm birth?
Present and past obstetric conditions such as short cervical length of <25mm, multifetal gestation, preterm membrane rupture, pre eclampsia, bleeding disorders
|
What is a problem of the psyche?
Tense abdominal and pelvic muscles work against contractions and maternal pushing efforts.
|
What is Preterm birth (PTB)
Birth that occurs between 20-0/7 and 36-6/7 weeks of gestation, regardless of birthweight.
|
What are signs of abruptio placentae?
Uterine tenderness localized at the site of the abruption, uterine irritabilty, high uterine resting tone, abdominal or low back pain, bleeding maybe hidden.
|
Deflexion Abnormalities
The poorly flexed fetal head presents a larger diameter to the pelvis than if flexed with the chin on the chest.
|
|
What is the cervical dilation after which no attempt is made to stop the labor?
Generally over 3 cms is the point of no return.
|
What are hypertonic contractions? (Hypertonic dysfunction)
Uncoordinated, irregular, short, painful, high uterine tone.
|
What is Low-birthweight (LBW)
Birthweight <2,500 grams (5 pounds, 8 ounces)
|
What is a partial placenta implantation?
The lower border of the placenta is within 3 cms but does not completely cover the internal cervical os.
|
What is a problem at delivery for breech birth?
The head may not descend quickly through the pelvis resulting in fetal injury from a compressed cord.
|
|
What is the fetal fibronectin fFN test?
A vaginal secretion test for readyness for preterm labor administered between 24 and 34 weeks.
|
What are the problems of the powers?
Ineffective contractions, Ineffective pushing
|
What is PPROM?
Rupture of membranes earlier than 37 weeks, with or without contractions.
|
What is abruptio placentae?
A dangerous conditions for the mother and fetus. Materna l-hemorrhage, consequent hypovolemic shock and clotting abnormalities. The fetus -asphyxia, excessive blood loss, prematurity
|
What is a maternal soft tissue obstruction?
A full bladder during labor.
|
|
What is the purpose of giving corticoid steroids to a woman in preterm labor at 27 weeks?
To accelerate fetal lung maturity.
|
What are the problems of the passenger?
Fetal size, fetal presentation or position, multifetal pregnancy or position, and fetal anomalies cause mechanical problems that interfere with contractions.
|
What is Preterm labor (PTL)
Labor that begins before 37 completed weeks gestation. Labor means regular contractions associated with cervical change, not just preterm contractions.
|
What is the effect of cocaine on the endometrial arteries?
Cocaine causes vasoconstriction and is a leading cause of abruptio placentae.
|
What are the factors that increase a woman' risk for a prolapsed cord?
Ruptured membranes AND
the fetal presenting part at a high station A fetus that poorly fits the pelvic inlet because of small size or abnormal presentation. Excessive amount of amniotic fluid |
