Cards

Term
Infant Respiratory Rate
Definition
30-60 BPM

Babies have short periods of apnea. If these periods are >15 seconds they must be evaluated.

If RR <30 may be analgesis or anesthesics. Apenea can be related to rapid heating or cooling

If RR>60 may be aspiration or diaphragmatic hernia

Term
Infant Heart Rate
Definition
80-100 BPM when sleeping

120-160 BPM when awake

Assess PMI at 4th ICS in the L MCL

Term
Infant Blood pressure
Definition
Systolic btween 60-80mmHg; Diastolic 40-50mmHg

4 point BP's are in all 4 extremities

Don't usually do infant BP

Term
Infant Hematocrit
Definition
Between 40-75. It's increased because fetal RBC's don't hold as much oxygen or live as long, so they need more.

Jaundice occurs when RBC's are broken down

Term
Infant WBC
Definition
9000-30000/mm3. Not a good way to look for infection. Instead look for left shift or temp instabilities.
Term
Convection
Definition
Flow from body surface to air. Change this by turning up the temp in the delivery room, getting the baby dry and covered
Term
Radiation
Definition
Heat goes to a cooler surface not directly touching the baby--like the sides of a warmer
Term
Evaporation
Definition
Like sweating
Term
Conduction
Definition
heat to a direct contact surface. It's vital that warming table preheats and that wet blankets are taken away.
Term
Cold Stress in Infants
Definition
Increased respiratory rate

Acidosis, blood is shunteda way from the periphery, so there's a decrease in O2 which causes a decrease in pH leading to acidosis

Term
Hyperthermia
Definition
Babies can't sweat. Overheating can result in dehydration, heat stroke and death
Term
Rental System
Definition
Should have one diaper in 1st 24 hours. Number of diapers= number of days old until there are 6-8 diaper changes perday.
Term
Weight loss
Definition
Child should not lose more than 10%. Will lose some in the first 3-5 days of life, but should gain it back in the next 10 days (be minimally back at birthweight)
Term
Glucose
Definition
Test all babies of diabetic moms, >4000g, <2500g and premies for glucose levels.

Babies of diabetic moms tend to have lower glucose because their pancreases have worked harder in utero.

Term
Unconjugated bilirubin
Definition
Insoluable and bound to circulating abumin, can leave the vascular system and permeate other tissues resulting in jaundice. It can also cross the BBB and result in kernicterious.

The liver conjugates bilirubin so that it can be excreted through meconioum. Increased fluids promotes this. Phototherapy also conjugates bilirubin.

Levels should be between 12-15mg. We treat once levels are above 12. Bili should increasel ess than 5mg/day.

Term
Kernicterous
Definition
Most serious complication of excess bili.

Can be found with conjugated bilirubin is >20mg/dl.

In this condition bili enters neuronal cells and destroys them==>CP, epilepsy, MR or death.

Term
Acrocyanosis
Definition
Common up to the first week. Hands and feet are blue when the baby is at rest. This is because the baby has immature circulation and the skin is the last thing that needs to be perfused.
Term
Caput Succedanum
Definition
Generalized easily idenitifide swolle, fluid filled area on teh scalp which extends accross the suture line of teh skull. Resolves by itself.

Sustained pressure on the presenting part (by something like vaccume pressure) causes compression of local vessels and slows venus return

Resolves in 3-4 days.

Term
Cephalohematoma
Definition
Collection of blood between the skull and periosteum. **does not cross the suture line!**

Appears after brith and spontaneously resolves after birth. (Hemolysis of RBCs as it resolves, so look for bilirubin levels).

Term
Subglial
Definition
Most dangerous hematoma! Between periosteum and gleal. Blood does cross teh suture line. Looks like caput, but you can see blood.

These are CONTINUING hemorrhages.

Term
Tremmors
Definition
Common and see in all infants when the child is upset. You should NOT see it when the infant is not crying. IF you DO see it when the baby is at rest, it could indicate hypoglycemia.
Term
Apgar score
Definition
Based on HR, RR, muscle tone, reflex irritability and color.

If less than 6, you need interentions!

Term
Low birth weight
Definition
<2500g
Term
Very low birth weight
Definition
<1500 g
Term
IUGR
Definition
Intrauterine growth restriction

Child follows a growth curve in utero and then suddenly falls off

Caused by a sucky placenta

Term
Eye prophylaxis
Definition
Goal: Prevent opthalmia neonatorum (gonnorrhea of the eye)

Erythromycin or tetracycline opthalmic ointment

Term
Umbilical cord
Definition
Want to prevent/detect hemorrhage or infection.

Assess for bleeding, edema, redness, purulent drainage. Clamp removed at 24-48 hours when it's dry.

Term
Circumcision
Definition
With no dressing put a glob of vasciline in the diaper. Check dressing every 15 minutes for the 1st hour. A drop of blood is normal, an active bleed is not.

With an active bleed you do surgicel (and do not vascelene)

After 24 hours a yellow pus is common. DO NOT touch. It's healing.

Term
Growth Spurts
Definition
Occur at 10 days, 3 weeks, 6 weeks, 3 months, and 4-6 months.

Require more feedings. Seem like you're feeidng all the time

Term
Signs of Adequate Intake
Definition
Infant feeds 8X per day

After latch, infant feeds 15-20 minutes (not more than 30 because this is burning more calories than it's taking in).

Infant appears satisfied

Infant has adequate out put

Infant has adequate weight gain

Mom has tugging feeling at nipple/warm feelings

Term
Frequency of feedings
Definition
Infants need 8-12 feedings per day

They should wake the child up q3h during the day and q4h during the night to feed.
