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

what are the principles of neonatal resuscitation

A

Q

what can you do to keep a new baby warm

A
  • get the baby dry as quickly as possible, vigorous drying also helps stimulate breathing
  • keep baby warm with warm delivery rooms and a heat lamp
  • babies under 28 weeks are placed in a plastic bag while wet and managed under a heat lamp

Q

how can you stimulate breathing in a new baby

A
  • stimulate the baby to prompt breathing, like vigorous rubbing with a towel
  • place babies head in a neutral position to keep the airway open
  • if gasping or unable to breath check for obstruction and consider aspiration

Q

how do you give inflation breaths in a neonate

A

two cycles of five inflation breaths (3 seconds each) to stimulate breathing and heart rate
if no response then 30 seconds of ventilation breaths
if still no response then chest compressions are used

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

  • blood cultures should be taken before antibiotics are given

Q

what is physiological jaundice

A

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

Q

why are breastfed babies more likely to get neonatal jaundice

A
  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

Q

when might haemolytic disease of the newborn occur

Q

what happens in haemolytic disease of the newborn

A

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

Q

what is phototherapy

A

phototherapy converts unconjugated bilirubin into isomers that can be excreted in the bile and urine without requiring conjugation

Q

how is phototherapy performed

A

  • 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

  • this leads to lung collapse (atelectasis) and it is more difficult for alveoli to expand

the baby will need an oesophagram several days after the surgery to look at what happens when fluid passes through their oesophagus

175
Q

what is bowel atresia

A

gap or narrowing in the bowel that leads to a segment of the bowel not developing correctly causing a complete blockage, not allowing fluid of food to pass through

176
Q

where is bowel atresia most common

A

in the small bowel - jejunum and ileum

177
Q

how common is bowel atresia

A

1/5000 babies

178
Q

how is bowel atresia diagnosed

A

in a few babies the diagnosis can be made on antenatal ultrasound scans

179
Q

how do babies with bowel atresia present

A

will present soon after birth with bilious vomiting
abdomen may be swollen
may be jaundiced
not passing meconium

180
Q

what is the initial management of bowel atresia

A

milk feeds stopped
NG tube to drain any fluid and air collecting in the stomach
IV fluids

181
Q

how is bowel atresia treated

A

surgery in the first few days of birth
- atresia cut away and bowel is joined together or a temporary stoma is made

182
Q

what will the bowel proximal to the atresia be like

A

may be dilated and dysmotile

183
Q

what is recovery like post bowel atresia surgery

A

dependent on type of atresia
- may be able to drink milk few days post operation
- those who have dilated bowel proximal to the atresia will take longer to get better
- may require parenteral nutrition

184
Q

what is the cause of bowel atresia

A

think it is due to reduced blood supply to sections of the bowel during development

185
Q

what is type 1 bowel atresia

A

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
Q

what is type 2 bowel atresia

A

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
Q

what is type 3 bowel atresia

A

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
Q

what is type 4 bowel atresia

A

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.

189

A

no
