Flashcards in Neonatal Resuscitation Deck (25)
What is a baby a newborn?
First few hours of life
When is a baby considered a neonate?
The first 28 days of life
When is a baby considered an infant?
1 month to 1 year
What is the ductus arteriosus?
The bridge that connects the left pulmonary artery and the aorta in neonates
It temporarily reroutes oxygenated blood from the mother away from the lungs of the fetus and into the baby's circulatory system
What are three physiological changes a fetus undergoes during the fetal transition process?
Fluid in alveoli is absorbed into lung tissue and replaced with oxygen
Umbilical cord is clamped
Alveoli become distended and blood vessels dilate which causes increased blood pressure
What is prostaglandin-E2?
Hormone that causes the ductus arteriosus to remain open
When does the fetus no longer receive prostaglandin-E2?
When the umbilical cord is clamped
What are four causes of fetal distress?
Neonates initial respiratory efforts are inadequate to force fluid from alveoli
Foreign material (meconium) blocks airway
Excessive blood loss (maternal trauma)
What are the five initial steps of neonatal resuscitation?
What is vernix caseosa?
Slippery substance covering newborns
What are the two methods for tactile stimulation?
Slapping/flickering soles of feet
Gently rubbing the back,trunk, or extremities
What are the three key assessment parameters for determining further neonatal resuscitation?
When should the apgar score be performed?
At 1 minute and 5 minutes after birth
What is the respiratory rate for a newborn?
40-60 breaths a minute
When will primary apnea reverse?
With simple stimulation by touching and suctioning
When will secondary apnea reverse?
Only with assisted ventilations
At what rate should you start compressions on a newborn?
Less than 60 beats
Even though there is a pulse it's not adequate enough for metabolic needs
What is acrocyanosis?
Cyanosis of extremities
Common finding with new horns. No therapy required
How much fluid do you give to a new born with hypovolemia?
10 mL/kg of normal saline over 5-10 minutes
Wha four drugs are used for neonatal resuscitation?
What amount defines neonatal hypoglycemia?
Blood glucose less than 40mg/dL
What is diaghragmatic hernia?
A hole in the diaphragm that allows bowels to move into the thoracic cavity
How can you tell if there was identical twins during birth?
There are two cords coming out of one placenta
How can you tell there are fraternal twins during birth?
There's 2 placentas each with one cord
