Prenatal Flashcards
Prenatal History
consists
-review of pregnancy
-past pregnancies
-mothers and fathers medical and genetic histories
Pregnant History
-determine is mother used any foreign substances
-xenobiotics
-medications
-any health problems the mother experienced during pregnancy (placenta previa, abruptio placentae, gestational diabetes, HTN)
Review of past pregnancies
-hx of congenital anomalies, still birth, genetic disorders
Perinatal History
-newborns weight, height, and Apgar score
-duration of labor
-use of analgesia or anesthesia
-type of delivery
-complications
-prolonged labor, meconium, staining or aspiration, use of forceps or vacuum
Apgar Score
-recored at 1 min and 5min after birth
-total of 10 points
-each test receives 0, 1, or 2
-repeat test every 5 min for 20min or until scores are above 7 in two consecutive tests

best out comes for newborns. at what gestational age?
born at 37-41 weeks
Premature and post-term gestational age?

LGA (large for gestation age)
-genetic risk factors: Beckwith-Wiedemann syndrome, Simpson-Golabi Behmel syndrome
-Maternal risk factors include maternal diabetes, and maternal obesity.
SGA (small for gestation age)
-intrauterine growth restrictions (IUGR)
caused by:
-maternal, placental, or neonatal factors
-maternal starvation, medical disorders, substance abuse, and intrauterine infection
-Placental injuries and structural anomalies
-Neonatal factors are inborn errors of metabolism, genetic syndromes, karyotypic abnormalities
2 types of SGA ?
Asymmetric IUGR
-head and length WNL
-Weight below 10th percentile
Symmetric IUGR
-reducation in both body and head growth
-intrinsic factors are the cause
Asymmetric IUGR
reductions of fetal nutrients:
-chronic HTN
-pre-eclampsia
-renal or cyanotic heart disease
-hemoglobinopathies
-abruptio placentae
-multiple gestation
-high altitude
Symmetric IUGR
intrinsic causes:
-chromosomal abnormalities
-congenital infections
New Born Vitals
temp: 36.1-37C
respirations: 30-60breaths per min
heart rate: 120-160bpm
check bp if cardio or renal problems suspected
below 112/74 is normal
Newborns skin
-turns red when crying
-when cold extremities turns bluish with a mottled tint
Macular stains may be associated with extracutaneous disorders, such as spinal dysraphism or Beckwith-Wiedmann syndrome
Hemangiomas
-strawberry marks (red/crimson macules)
-vascular neoplasm
-disappear by age 5
Milia
