child health Flashcards
preterm
a birth that occurs before 37 completed weeks of gestation
term
a birth between 37 weeks and 42 weeks of gestation
post-term
a birth that occurs after 42 weeks of gestation
normal weight for a baby
2.5-4kg
what happens in the 3rd trimester
- Daily weight gain of 24g during 3rd trimester
- Approx. 7g of fat per day in last 4 weeks
- Transplacental transfer - iron, vitamins, calcium, phosphate and antibodies
what vitamin should be given at birth
Vitamin K given in the newborn period given to prevent haemorrhagic disease of the newborn - clotting (vitamin K dependent)
list some complications of a pre-term pregnancy
- hypothermia
- Neonatal sepsis
- Respiratory distress syndrome
- Retinopathy of prematurity - usually 6-8 weeks after delivery
a higher apgar score is worse for babys
false - high score is good
give respiratory complications of the newborn

- Tracheo-oesophageal fistula
- Diaphragmatic hernia
give cardiac complications of the newborn
Hydrops foetalis - rhesus disease, chromosomal
persistent pulmonary hypertension of the newborn (PPHN)

give initial management of a sick newborn
- Stabilise temperature - 36.5-37.4℃
- Airway and breathing - gentle support (e.g. open airway), consider oxygen as needed
- Circulation - fluids, inotropes
- Metabolic homeostasis - glucose management, correction of acid-base balance
- Antibiotics
give causative organisms of early onset sepsis of the newborn
gram negative group B streptococcus
give causative organisms of LATE onset sepsis of the newborn (after birth)
- Gram negatives
- Staph. aureus
- Coagulase negative staphylococci
management of neonatal sepsis
- Prevention - hand washing, vigilance, infection screening
- Antibiotics
- Supportive measures
which type of jaundice can be Both physiological and pathological
unconjucated
conjugated is always pathological
define prolonged jaundice
over 14 days in a term baby or 21 days in a preterm baby
give investigations for early jaundice
FBC/SBR/DCT, investigate underlying cause
give investigations for prolonged jaundice
FBC/LFTs/SBR/TFTs, further investigation if required
give management for early and prolonged jaundice
early
- Phototherapy
- Adequate hydration
- Resolve underlying cause
prolonged
- Resolve underlying cause
outline NRDS
Affects 75% of infants born before 29 weeks - born before the lungs start producing adequate surfactant
pathophysiology of NRDS
- Inadequate surfactant leads to high surface tension within alveoli
- This leads to atelectasis (lung collapse)
- This leads to inadequate gaseous exchange
clinical presentation of NRDS
- Respiratory distress - tachypoea, grunting, intercostal recessions, nasal flaring, cyanosis
- Worsens over minutes to hours til 2-4 days then gradual improvement
management for NRDS
- Maternal steroid
- Surfactant replacement
- Ventilation (non-invasive preferred over invasive)
define neonatal abstinence syndrome
Refers to the withdrawal symptoms that happens in neonates of mothers that used substances in pregnancy
clinical presentation of NAS
- CNS: irritability, tremors, seizures
- Vasomotor and respiratory: sweating, unstable temperature, tachypnoea
- Metabolic and GI: poor feeding, regurgitation/vomiting, hypoglycaemia
management for NAS
notes should have an alert which allows for extra monitoring and management
kept in hospital for 3 days on a NAS chart to monitor for withdrawals
support in a quiet and dim environment
what BGL defines neonatal hypoglycaemia
BGL < 2.6 mmol/l
presentation of neonatal hypoglycaemia
- Lethargy
- Jitteriness
- Seizure activity
management of neonatal hypoglycaemia
keep baby warm
feed
if unsafe to feed IV glucose
define birth asphyxia
Occurs when a baby doesn’t receive enough oxygen before, during or just after birth
causes of birth asphyxia
- Maternal shock
- Intrapartum haemorrhage
- Prolapsed cord, causing compression of the cord during birth
- Nuchal cord, where the cord is wrapped around the neck of the baby
give a major complication of birth asphyxia
Hypoxic Ischaemic Encephalopathy - Multi-organ damage due to tissue hypoxia
what can babies with HIE benefit from
therapeutic hypothermia - reduces the risk of cerebral palsy, developmental delay, learning disability, blindness and death
describe hydrocephalus
> Describes cerebrospinal fluid (CSF) building up abnormally within the brain and spinal cord
- Result of either over-production of CSF or a problem with draining or absorbing CSF
clinical presentation of hydrocephalus
- Enlarged and rapidly increasing head circumference
- Bulging anterior fontanelle
- Poor feeding and vomiting
- Poor tone
- Sleepiness
Investigations and management of hydrocephalus
transcranial ultrasound
Ventriculoperitoneal shunt
define necrotising enterocolitis
> Disorder affecting premature neonates, where part of the bowel becomes necrotic
- Serious intestinal injury to a relatively immature gut (e.g. premature baby being fed too early) resulting in perforation
clinical presentations of necrotising enterocolitis
- Intolerance to feeds
- Vomiting, particularly with green bile
- Generally unwell
- Distended, tender abdomen
- Absent bowel sounds
- Blood in stools
what is the investigation of choice for necrotising enterocolitis and what will it show
AXR
- Dilated loops of bowel
- Bowel wall oedema
- Gas in bowel wall
- Gas in peritoneal cavity (pneumoperitoneum) indicates perforation
management of necrotising enterocolitis
- Nil by mouth, clindamycin and cefotaxime
- Immediate referral to the neonatal surgical team
describe intraventricular heamorrhage
Bleeding into the ventricles inside the brain; in neonates occurs mainly in premature infants
what is the most common type of intraventricular haemorrhage
Germinal matrix is the most common type - related to perinatal stress affecting the highly vascularised germinal matrix
define jejunal atresia
Congenital anomaly characterised by obliteration of the lumen of the jejunum
clincial presentation of jejunal atresia
Neonates typically present with abdominal distension and bilious vomiting within the first 24 hours of birth
management of jejunal atresia
surgical correction
define malrotation
Congenital anatomical anomaly that results from an abnormal rotation of the gut as it returns to the abdominal cavity during embryogenesis
clinical presentation of malrotation
- Most common presentation in the infant is midgut volvulus - presents with bilious (green) vomiting
- Up to 40% of patients with malrotation show signs within the first week of life
give investigations and management for malrotation
upper GI contrast and followthrough
surgical correction
outline meconium ileus (BUBBLY APPEARANCE)
> Refers to a neonatal bowel obstruction of the distal ileum due to abnormally thick and impacted meconium
