ch 57 amniotic fluid exercise 1& 2 Flashcards
Produced by the umbilical cord and membranes, the fetal lung, skin, and kidney
Amniotic fluid
Sonographer surveys uterine cavity for visual determination of amniotic fluid present
Subjective assessment of fluid
Each of the four uterine quadrants is evaluated with transducer perpendicular to the table in the deepest vertical pocket without fetal parts; the four quadrants are added together to determine this.
Amniotic fluid index (AFI)
Too little amniotic fluid; associated with intrauterine growth restriction, renal anomalies, premature rupture of membranes, postdate pregnancy, and other factors.
Oligohydramnios
Fatty material found on fetal skin and in amniotic fluid late in pregnancy
Vernix caseosa
Method used to determine the amount of amniotic fluid
Maximum vertical pocket
Structure that forms early in gestation and surrounds the embryo
Amniotic cavity
Too much amniotic fluid
Polyhydramnios
Inability of the placenta to provide adequate blood/nutrient supply to the fetus because of underlying maternal disease.
Placental insufficiency
Condition in which the amniotic bag breaks, labor has not begun, and the pregnancy is less than 37 weeks gestation
Premature rupture of membranes (PROM)
Condition in which the amniotic bag breaks with labor or just after labor begins
Spontaneous premature rupture of membranes
Scars within the uterus secondary to previous gynecological surgery
Uterine syncechiae
Abnormal serous fluid collection found in the abdomen or pelvis
Ascites
Accumulation of abnormal fluid collection caused by rhesus incompatibility
Immune hydrops fetalis
Generalized swelling and edema of skin throughout the body
Anasarca
Abnormal collection of fluid surrounding the heart measuring greater than 2 mm
Pericardial effusion
Multiple fibrous strands of amnion that develop in utero that may entangle fetal parts to cause amputations or malformations of the fetus
Amniotic band syndrome
Bacterial infection of the fetal membranes usually due to upward ascent of a vaginal infection
Chorioamnionitis
Accumulation of abnormal fluid collection not caused by rhesus incompatibility
Nonimmune hydrops fetalis
Abnormal fluid collection in the thoracic cavity
Pleural effusion
Administered to pregnant woman to help accelerate fetal lung maturity
Corticosteroid therapy
Abnormal accumulation of fluid or edema found in at least two fetal areas
Hydrops fetalis
Acquired uterine condition characterized by the presence of intrauterine scars
Asherman’s syndrome
