Q

what is the function of surfactant

A

to reduce the surface tension of the fluid in the lungs, and keeping alveoli inflated and maximising the surface area of the alveoli
- increases lung compliance

Q

what are issues surrounding neonatal resuscitations

A
  • babies have a large surface area to weight ratio and get cold easily
  • babies are born wet so loose heat rapidly
  • babies are born through meconium which may enter their mouth and airway

Q

why is it important to give vitamin K after birth

A

babies are born with a deficiency of vitamin K. As it is required for normal clotting of blood vitamin K is given to all babies via IM injection as standard practice
- Can also give it orally as drops but takes longer to act and requires three doses

60
how do you treat presumed sepsis
- if one risk factor or clinical feature then monitor the obs and condition for >12 hours - if two or more risk factors start antibiotics - antibiotics should be given if there is a single red flag - antibiotics need to be given within 1hr of deciding to give them - blood cultures should be taken before antibiotics are given - check baseline FBC and CRP -perform LP if meningitis suspected
61
what do nice recommend as first line antibiotics in presumed sepsis
benzylpenicillin and gentamycin alternatively given third generation cephalosporin (cefotaxime) may be given as an alternative in lower risk babies

72
what is the intention of therapeutic hypothermia
to reduce inflammation and neurone loss after hypoxic injury - reduces the risk of cerebral palsy, developmental delay, learning difficulties, blindness and death
73
what causes jaundice
high levels of bilirubin in the blood
74
what are the two ways conjugated bilirubin is excreted
via the biliary system into GI tract urine
75
what is physiological jaundice
fetal red blood cells break down more rapidly than normal RBC releasing lots of bilirubin normally this is excreted via the placenta however after birth this is no longer available this leads to a normal rise in bilirubin after birth, it normally resolves completely by 10 days old
76
what are symptoms of physiological jaundice
mild yellowing of the skin and sclera from 2-7 days otherwise normal healthy baby
77
what are causes of neonatal jaundice
increased production: haemolytic disease of the newborn, ABO incompatibility, haemorrhage, intraventricular haemorrhage, cephalo-oedema, polycythaemia, sepsis and DIC. G6PD deficiency decreased clearance of bilirubin: prematurity, breast milk jaundice, neonatal cholestasis, biliary atresia, endocrine disorders (thyroid/pituitary) and gilbert syndrome
78
is jaundice in the first 24 hours of life normal?
no it is pathological - needs urgent investigations and managed (think sepsis)
79
why might premature babies get jaundice
due to the immature liver - the process of physiological jaundice is exaggerated
80
what is Kernicterus
brain damage due to high bilirubin levels
81
who are more likely to get jaundice, those who are bottle fed or breastfed
those who are breastfed
82
why are breastfed babies more likely to get neonatal jaundice
1. components of breast milk inhibit the ability of the liver to process the bilirubin 2. breastfed babies are more likely to become dehydrated if not feeding adequately 3. inadequate breast feeding may lead to slow passage of stools, increasing absorption of bilirubin in the intestines
83
what is haemolytic disease of the newborn
it is caused by incompatibility between the rhesus antigens on the surface of the red blood cells of the mother and the fetus
84
when might haemolytic disease of the newborn occur
when a woman is rhesus negative and her baby is rhesus negative - mother becomes sensitised to the resus D antigens and will normally cause issues in the second + pregnancy
85
what happens in haemolytic disease of the newborn
the mothers anti-D antibodies can cross the placenta into the fetus, and if that fetus is rhesus positive this can cause the immune system of the fetus to attack their own cells this leads to haemolysis, anaemia and high bilirubin levels
86
when is jaundice considered prolonged
more than 14 days in full term babies more than 21 days in premature babies
87
what can cause prolonged jaundice
biliary atresia hypothyroidism G6PD deficiency
88
what investigations should be done in neonatal jaundice
FBC and blood film - polycythaemia or anaemia conjugated and unconjugated bilirubin blood type testing direct coombs test for haemolysis thyroid function blood and urine cultures if infection suspected G6DP levels
89
what is the management for neonatal jaundice
- monitor total bilirubin levels and plot on treatment threshold charts - if total bilirubin reaches threshold then they will be commenced on treatment - phototherapy - exchange transfusion
90
what is phototherapy
phototherapy converts unconjugated bilirubin into isomers that can be excreted in the bile and urine without requiring conjugation
91
how is phototherapy performed
- remove clothing down to nappy and eye patches to protect eyes - baby is put into a light box which shines blue light onto the babies skin - bilirubin is monitored during treatment - once phototherapy is complete rebound bilirubin should be measured 12-18 hours after stopping to ensure levels dont rise again
92
how does kernicterus present
less responsive, floppy, drowsy baby with poor feeding
93
what is the long term issues with kernicterus
the damage to the nervous system is permanent - cerebral palsy - learning difficulties - deafness

103
how is apnoea of prematurity managed

it affects premature neonates, born before the lungs start to produce adequate surfactant
105
what is seen on chest Xray in respiratory distress syndrome

106
what is the pathophysiology of respiratory distress syndrome
- inadequate surfactant leads to high surface tension within alveoli - this leads to lung collapse (atelectasis) and it is more difficult for alveoli to expand - this leads to inadequate gaseous exchange resulting in hypoxia, hypercapnia and respiratory distress
107
what is the management of respiratory distress syndrome
1. antenatal steroids given to mothers with suspected or confirmed preterm labour 2. intubation and ventilation to assist breathing 3. endotracheal surfactant which is an artificial surfactant delivered into the lungs via an endotracheal tube 4. continuous positive airway pressure to keep lungs inflated while breathing 5. supplementary oxygen to maintain between 91-95% in neonates

120
are babies born with bronchopulmonary dysplasia
no the condition results from damage to the lungs usually caused by mechanical ventilation and long term use of oxygen
121
what can cause bronchopulmonary dysplasia
can occur when newborns lungs are underdeveloped at birth, requiring the use of a ventilator or oxygen therapy. because their lungs are vulnerable high amounts of inhaled oxygen and pressure may overstretch the alveoli causing inflammation and damage to the inner lining of the airways, alveoli and blood vessels surrounding them

184
what is the cause of bowel atresia
think it is due to reduced blood supply to sections of the bowel during development
185
what is type 1 bowel atresia
The blockage, which can be partial or complete, is caused by a web-like membrane that forms inside the intestine while the baby is developing in the womb. The baby’s intestine usually grows to normal length.
186
what is type 2 bowel atresia
The blockage results when one or more segments of the intestine forms a “blind end.” The blind ends are connected by a cord of fibrous tissue, and the baby’s intestine usually grows to normal length.
187
what is type 3 bowel atresia
the segments that end in blind ends are not connected by a fibrous cord. As a result, the blood supply within the intestine is interrupted, and the baby’s intestine usually fails to grow to a normal length. If the end of the intestines below the blockage is not coiled, the blockage is called a type IIIa atresia. Sometimes, however, that end forms a spiral “apple-peel” shape. Such a blockage is known as a type IIIb atresia.
188
what is type 4 bowel atresia
The blockage involves many obstructions, giving the intestine a “string-of-sausages” appearance. The blockages may include various combinations of types I, II and III atresia. The baby’s intestine is significantly shorter than normal.
