Thermoregulation
Heat loss due to conversion of fluid on skin to air vapor
What is evaporation?
Reduced by
- throughly drying newborn
- removing wet linens
-delaying initial bath between 6 & 24 hrs
APGAR is assessed at _____ & _____.
What is 1 minute & 5 minutes?
Tool used to perform gestational age assessment
Ballard Scale
37- 41 6/7 weeks of gestation
What is term?
When initial newborn screen (PKU) should be performed?
What is 24-48 hours of life?
Heat transfers from newborn's body to the surrounding air and influnenced by:
-amount of skin exposed to air
- air temp
- speed or turbulence of air movement
What is convection?
-reduced by swaddling and using a hat
-eliminating sources of drafts
-maintaining a warm room temp
Cyanosis of the hands, feet and sometimes oral area despite being pink centrally
What is acrocyanosis?
Serves as the fetal lungs and is responsible for oxygen and CO2 exchange as well as waste removal
What is placenta?
2 years or when they exceed weight/length allowed by car seat manufacturer
Heat loss generated by contact between cool surfaces and newborn's body
What is Conduction?
Reduced by
-skin to skin
-preheating radiant warmers
You just delivered a baby boy. His body is pink, but his hands and feet are blue. Vital Signs are P 110, R rapid and irregular. He has a weak cry when stimulated and resits attempts to straighten his leg
What is 7?
A1 P2 G1 A1 R2
Pink, macular lesions located located on the eyelids, forehead, neck, nose and upper lip
Most common vascular birthmarks seen in 30-50% of newborns
WHat are nevus simplex lesions or stork bites?
Compression of chest during birth removes _______ from newborns lungs. _____ replaces the ____ in the lungs with chest reexppansion at birth
Compression of chest during birth removes FLUID from newborns lungs. AIR replaces the FLUID in the lungs with chest reexpansion at birth
Indications for Car Seat Study
< 37 weeks or <2500 grams.
Heat Loss transferred from solid objects not in direct conflict with the neonate
What is radiation?
Reduced by
-using prewarmed radiant warmers
- moving cribs away from cooler exterior walls
It has been 5 minutes since your patient delivered her baby. The infant is crying weakly ans is curling his arms and legs. He is pink all over with a pulse of 90 and weak respirations. WHat is the APGAR Score?
6
A2 P1 G1 A1 R1
Sound produced on expiration when air passes through a partially closed glottid
What is grunting?
What is 32-34 weeks
2 nonivasive measured to screen newborns for hearing loss
What are Automatic Acoustic Brainstem Response (ABR) & Evoked Otoacoustic Emmisssions (OAE)?
ABR: This test records activity of the cochlea and auditory brainstem pathway. Electrodes are placed on skin surface of newborn's head
OAE: Records acoustic responses in the ear canal to indicate the outer hair cell function. Small microphones placed in the newborn's ear
Newborns have limited ability to shiver, therefore heat must be genersted through ___________
What is nonshivering thermogenesis?
Newborns experiencing nonshivering thermogeneis utilize higher amounts of oxygen and glucose.
A neonatal patient has pink color, a pulse rate of 102, respiration rate o 27. SHe grimaces in repsonse to stimuli, has limited muscle movement. This patient has an APGAR score of?
A2 P2 G2 A0 R1
Vibrations heard due turbulent blood flow.
They are common in ____ ____ ___ ____ ___
What is murmur?
What is first 48 hours of life?
Describe neonatal cardiovascular changes.
- With the first breaths, the fetal pulmonary vascular bed dilates and blood flow to the newborn's lung increases
- Pressure in R atrium decreases
-Pressure in L atrium decreases
- Foramen ovale, ductus arteriosis and ductus venosus close spontaneously as a result of these changes
5 AAP recommendations for Safe Sleep
1. Back to sleep 2. Roomsharing without bedsharing 3. Keep soft objects, pillows and loose bedding out the the crin to reduce risk of SIDS, suffocation, entrapment and strangulation. 4. Infant sleep clothing prefereable to blnakets 5. No bumpers 6. Never leave baby on a sofa, armchair or in a sitting device to sleep 7. Firm sleep surface with a fitted sheet and firm crib mattress
