OB High Risk Flashcards
High Risk NB
What is AGA, SGA, LGA and LBW stand for?
AGA is Appropriate for Gestational Age
SGA is Small for Gestational Age
LGA is Large for Gestational Age
LBW is Low Birth Weight
What are SGA babies at risk for?
Asphyxia, hypoglycemia, hypothermia, hypocalcemia
What are LGA babies at risk for?
Hypoglycemia, hypothermia, hypocalcemia, polycythemia and trauma
Define premature
anything after 20 weeks but before 37th week COMPLETED regardless of weight
“red gummy bears” red sticky skin, floppy, no fat, poor suck, and a big head
At risk for RDS, anemia, neuro and cardiac problems
Define Post-mature
anything beyond completion of 42nd weeks of gestation
“panteen babie” Long and skinny, long finger nails, no vernix, wrinkly leathery skin.
At risk for trauma, hypoglycemia (check CBG immediately), maconium aspiration (suction, dry, warm, then stimulate after airway clear)
*Why do we give SGA and preterm babies gavage feedings?
So that the GI doesn’t die.
*Clarification.
list 4 factor that affect the growth of the baby
Maternal: smoking alcohol Maternal age Nutritional factors Diabetes Substance Abuse Hypertension Poor utero-placental insufficiency Mulit para's
Fetal: genetic anomalies congenital anomalies multiple gestation IUGR
Define Asphyxia
Anything that prevents O2 delivery
Hypoxia, low O2, acidosis, hypercapnia (high CO2 levels)
can happen in utero or at birth; must get the baby breathing within 2 mins of being delivered
List three common risk factors for asphyxia
uteroplacental insufficiency-this could be previa, abprution
in utero maconium passage
maternal drugs during labor
congenital anomalies
Anything that can cause fetal distress to baby.
what is the difference between CPR and PALS
CPR- Cardio Pulmonary Resuscitation
PALS- Pediatric Advanced Life Support (AMBU Bag/ bag valve mask)
Describe respiratory distress syndrome and how it happens
leading cause of problem in premies
Deficiency in lung surfactant causing progressive atelectasis (alveoli collapse)
If C-Section think Squeeze
If Vag delivery think immature lungs
Name three symptoms of RDS
Grunting cynaosis on RA tychpnea pallor retractions nasal flaring
What are three GOALS for treating RDS
Improve oxygenation
Maintain lung volume
Minimize O2 consumption-by minimizing 02 consumption it helps with maintaining temp, maintaining B/P, maintaining blood sugar
If mother given Mag Sulfate to slow labor we want to give steroids to help the baby’s produce more lung surfactant
culture to rule out pneumonia
Describe maconium aspiration
Aspiration of maconium at birth in post mature, IUGR (intrauterine growth restriction), or stressed infants.
what three things can cause a NB to get pneumonia
Aspiration of infected amniotic or cervical fluids
Blood borne infections
Infections from poor hand hygiene
(GBS- Group Beta )
S/S: tachypnea, pallor, grunting, flaring of the nostrils, tachy/bradycardia, hypothermia
Culture everything, and broad spec antibiotics
Describe TTN (transient tachypnea of NB)
Delayed resorption of lung fluid d/t c-sections (no squeeze)
s/s: tychpnea, hypoxia
tx: may need ventilation or O2 support, keep baby crying to get fluid out
what is NEC (Necrotizing Enterocolitis)
Necrotizing Enterocrolitis
ischemia and necrosis of the GI tract leading to perforation of the intestine
s/s: similar to a bowel obstruction, big belly, no appetite, bloody stools
TX: NPO, rest gut, blood transfusion, TPN feeding, possible temporary colostomy
what are the three C’s to asses in a NB that has a TEF
Chocking
Coughing
Cyanosis
Use pacifier to promote gastric juices
montior respers, HOB up, NPO and suction
what is the difference between gastroschisis and omphalosele
gastroschisis usually occurs to the right of the umbilicus
omphalosele occurs through the umbilical cord (starts with an O- round like a belly button)
For both we are going to put in plastic bag above baby, and use moist sterile gauze around opening
which side would you place a NB who is post of for treatment of gastroschisis and omphalosele
Make sure the baby has a pacifier in mouth with NG tube feedings
Lay on right side to ensure digestion
what is an umbilical hernia
a protrusion of part of an organ through ABD opening
how does retinopathy of prematurity happen
this happens when there is a high o2 concentration for a long period of time causing vasoconstriction and causing retinopathy (blindness)
what is the difference between cyanotic and acyanotic defects of the heart
cyanotic: Transportation of great vessels, tetrology of fallot and Tricpsid atresia. (tacypnea and tachycardia. count HR for one full minute- no half stepping)
acyanotic: left ventricle doesn’t develop. give prostaglandin E to help close
describe why the RH factor of a mother is so important
If mom is Rh- it can cause the moms antibodies to attack the fetal cells. Therefor, if mom is RH- Rogham must be give at 28 weeks, 72 hours after birth and anytime any trama has happened during pregnancy.
