Q

What is the treatment of meconium aspiration?

A

Do suction, intubate and ventalate (if v unwell)

Q

How do you investigate a blue baby?

A

Sepsis screen

Blood gas and glucose

CXR, ECG, ECHO

Pulse oximetry

Hyperoxia Test- breathe 100% o2 for 10 mins. Does this improve blood gas? If not cardiac problem

Twins- twin to twin transfusion- smaller one doesn’t have glycogen

Q

What do you do for severe jaundice in a baby?

A

Incubate and IV fluids

Phototherapy and rarely exchange transfusion

17
Q

What is brith asphyxia?

A

Lack of oxygen at birth leads to multi organ dysfunction

18
Q

What are the causes of birth asphyxia?

A

Placental problem

Long difficult delivery

Umbilical cord prolapse

Infection

Neonatal airway problem

Neonatal anaemia (rhesus negative)

19
Q

What are the two stages of hypoxic damage in birth asphyxia?

A

Stage 1- within minutes, cell damage due to lack of blood flow and O2

Stage 2- repercussion injury, can last days or weeks, toxins released form damaged cells

20
Q

What is hypoxic ischemic encephalopathy?

A

Damage to the baby due to birth asphyxia

Loss of reflexes

Clonus

21
Q

What is the management of hypoxic ischemiac encephalopathy

A

Rectal thermometer

Intubator- for morphine

Kept at 33-34 degrees then gradually rewarmed

Manage seizures, cardio and resp problems

Fluid restriction (cerebral oedema)

22
Q

What surgical problems should we know about

A

Oesophageal atresia

Duodenal atresia and other GI atresias (polyhydraminos)

Failure to pass stool

Abdo wall defects

Diaphragmatic hernia

23
Q

What are the causes of failure to pass stool (48 hours no poo)

A

Constipation

Large bowel atresia

Imperforate anus (+/- fistula)

Hirschprungs disease- not enough nerves is lower bowel

Meconium ileum (think CF)

24
Q

What are the common abdo wall defects they get

A

Exophalemous hernia?- hernia into umbilical cord (multiple defects)

Gastrochesis- abdo wall doesn’t close property (isolated)

25
Q

What are the complications of abdo wall defects?

A

Heat loss

Need fluid

26
Q

Discuss a diaphragmatic hernia?

How is it treated?

A

Usually occurs on left

Bowel (or abdo organs) move through diaphragm causes lung problems

Need intubated, surgery,

27
Q

What is neonatal abstinence syndrome

A

Withdrawl from maternal addictive substances

Usually opioids, benzodiazepines, cocaine, amphetamine

28
Q

How do you treat neonatal abstinence sydrome?

A

Monitor/ diagnosis

Finnegan score

Urine toxicology

Give Morphine or Phenobarbitone

Discharge planning

Babies may have BBV or other diseases
