This is a brief video on fetal growth abnormalities, including babies and fetuses that are too small and too large. • I created this presentation with Google Slides. • Images were created or taken from Wikimedia Commons • I created this video with the YouTube Video Editor. • ADDITIONAL TAGS: • Fetal • growth • abnormalities • By Yehudamalul - Own work, CC BY-SA 3.0, https://commons.wikimedia.org/w/index... • LGA = weight above 90th% • Diagnosed with fetal ultrasound • Risk factors: (gestational) diabetes, obesity, maternal weight gain, advanced maternal age, male female, genetic disorders of overgrowth (Beckwith– Wiedemann syndrome) • Macrosomia (literally big body) - baby weighing over 4000-4500 g • Complications include shoulder dystocia and other birth trauma, jaundice, poor APGAR, hypoglycemia in neonatal period • SGA = weight below 10th% • Intrauterine growth restriction (IUGR) = fail to achieve potential size • Symmetric:asymmetric → 20%:80% • Asymmetric = abdomen smaller than head • Fundal height 3 cm smaller than expected • Risk factors: maternal htn, diabetes, SLE, CVD; placental infarction, abruption, velamentous cord (insert into fetal membranes, travel between amnion and chorion • Causes: teratogens, smoking, alcohol, cocaine, htn, preeclampsia, infections (CMV, rubella, etc), anemia, multiple gestations, genetic/chromosomal abnormalities, poor placental perfusion, poor nutrition, anatomic abnormalities. • Identify cause with karyotype, ultrasound, infection screens • Monitor baby with ultrasounds, nonstress tests, doppler velocimetry • Bed rest not found to improve outcomes • Induce delivery if fetus in distress, mom’s health is in danger, baby continues to drop off growth curve • Smaller infant has greater morbidity and mortality • Birth weights: • LBW low birth weight - less than 2500 g (5 lb 8 oz) • very low birth weight VLBW - less than 1500 g (3 lb 5 oz) • extremely low birth weight ELBW - less than 1000 g (2 lb 3 oz)
