Week 5 - D - The sick term infant - Infection, Pregnancy/birth complications, Congenital Anomalies, Metabolic diseases Flashcards
How long does the neonatal period last? How long does the puerperal period last?
The neonatal period lasts 4 weeks - the first 28 days of life
The peuperal period lasts approx 6 weeks - this is the time it takes for the mothers body, including hormones and uterus levels - to return completely to their non-pregnant state
What is the most common cause of death in children under 5 years in the neonatal period?
This would be prematurity The neonatal period is the transitional time from intrauterine to independent existence
A neonate might become unwell at delivery, first few hours of life or days, or up to 28 days post delivery What is the scoring system used to quickly summarise the health of the newborn? When is it carried out?
This is the Apgar Score It is assessed at 1 minute and 5 minute post delivery
What are the 5 different sections assessed when using the apgar scoring system?
Appearance - colour Pulse Grimace - reflex irritability (cough/cry) Activity - muscle tone Respiration (breathing / crying)
When the baby is born, a newborn clinical assessment is carried out Inspect tone (activity), level of arousal (grimace), colour (appearance) and vital signs (heart rate and respiration) - basically APGAR What is the normal resp rate and heart rate of the newborn?
Normal resp rate of a newborn is 40-60 breaths per minute Normal heart rate of newborn is 120-160 bpm
In the intial management of the sick term infant, it is important to assess the infants temperature, ensure the infant has proper airway control and ventilate if required, also assess the infants circulation and give fluid if required What do you have to be careful of when giving fluids to the infant?
Do not want to cause central pontine myelinosis
WHat is the chest compression to ventilation rate in a neonatal resuscitation? Should the neonate be commenced on 100% oxygen initially?
Resuscitation of term infants should commence in air.
The recommended compression: ventilation ratio for CPR remains at 3:1 for newborn resuscitation.
Use 21-30% oxygen concentration initially in preterm infants
If the child happens to go into arrest - it is important to be aware of how to carry out the CPR Is arrest in infants more commonly due to respiratory or cardiac arrest? What is the difference when opening the infnt and adult airway?
Respiratory arrest is more common in infants
Cardiac arrest is more common in adults
- When opening the adult airway - it is important to tilt the head/chin
- In infants the airway is open when the head is in neutral so no need to tilt
After ensuring the airway is patent, what is the difference between adults and infant for listening feeling for breathing for 10 seconds and chcecking for signs of life ie carotid pulse?
- Adults
- * Ensure airway is patent - head/chin tilt
- * The look and feel for signs of breathing/signs of life (carotid pulse) for 10 seconds
- * Then proceed to carry out chest compressions
- Infant
- * Ensure airway is patent - head in neutral
- * Look and feel for signs of breathing for 10 seconds
- * Deliver 5 rescue breaths
- * Look & feel for signs of life 10secs- cough/gagging
Infants After looking for signs of life - start chest compression What is the rate of rescue breaths to chest compressions in infants/adults? What is the depth of the compression? Is CPR in a child carried out in the same way as in an adult or infant?
Infant - 15 chest compressions to 2 rescue breaths - 1/3rd of the chest depth for the chest compressions
Adult - 30 chest compressions to 2 rescue breaths - 5-6cm depth for chest compression at a rate of 100-120 compressions per minute
CPR in a child is done the same way as in an adult apart from the chest compressions remain as 1/3rd of the chest
Ongoing management of the sick term infant can include further support if necessary The sick baby is usually down to any of 4 different disturbances * Congenital anomalies * Infection * Pregnancy/birth related * Metabolic disturbances What are the three types of infectants?
Viral bacterial and fungal
What are the two common types of bacterial infection within the first 48 hours of birth in the neonate?
Within the first 48 hours Group B strep and E.coli are the common infectants
- Group B strep - colonises mothers vagina
E-coli - bowel commensal
What is the common causes of meninigits in a neonate?
What is the most common cause of meningitis in children? (up to 10 years of age)
Mneingiits in neonates - GroupB strep, Listeria monocytogenase, E.coli
- Group B strep - colonises vaginal flora
- E.coli - gut commensal
- Listeria monocytogenase - eating cheese and pate etc during pregnancy (bacteria found in these that can cross the placenta)
Staph aureus and staph epidermis are other causes of bacterial infections in neonates What is the acronym used to sum up the viral infections that can cause congenital defects in babies?
TORCH T - toxoplasmosis O - others R - rubella C - cytomegalovirus H - herpes
Sick baby Infection Pregnancy /birth related problems Congenital anomalies Metabolic disturbances What pregnancy.birth related problem can cause neonatal seiazures?
This could be hypoxic ischaemic encephalopathy
