Liver Flashcards
What are causes of unconjugated prolonged jaundice
Breastmilk infection Haemolytic anaemia Hypothyroidism High GI obstruction Crigler-Najjar syndrome
What are causes of conjugated prolonged jaundice
Bile duct obstruction (biliary atresia, cholechodal cyst)
Neonatal hepatitis syndrome (infection, error of metabolism, alpha-1-antitrypsin, galactosaemia)
How do you determine what kind of intervention a baby needs for jaundice?
using bilirubin threshold table
When do you consider intensified phototherapy
if serum bilirubin levels are rising rapidly
if bilirubin fails to repost to phototherapy
How do you assess for underlying disease in jaundice
- measure serum bilirubin
- Htc
- Blood group
- DAT
- Find out if mother received prophylactic anti D
- FBC, blood film
- blood G6PD
- LFT
- Sepsis screen if infection suspected
When do you perform exchange transfusion
If above threshold on graph OR baby shows signs of bilirubin encephalopathy
What must you NOT stop during exchange transfusipn
Phototherapy
What resources can you give for neonatal jaundice
NHS Choices Neonatal Jaundice Factsheet
The Breastfeeding Network (information and support for breastfeeding mothers)
Bliss (premature/sick babies)
What is biliary atrasi
Progressive fibrosis and obliteration of extra hepatic and intrahepatic biliary tree
What is the cause of biliary atrasia
UNKNOWN
What is the outcome for untreated biliary atresia
death within TWO years
What is the presentation for biliary atresia
jaundice pale stools normal BW faltering groeth hepatomegaly, splenomegaly
What are investigations for biliary atrasia
Raised conjugated bilirubin abnormal LFT Fasting abdo ultrasound Cholangiogram Liver biopsy
What is management for biliary atrasia
Kasai hepatoportoenterosotomy
Liver transplant
Surgical intervention is recommended within 60 days of life
What are complications of biliary atresia
growth failure
portal hypertension
cholangitis
ascitis
How do you manage complications of biliary atresia
ursodeoxycholic acid (promote bile flow)
fat soluble vitamins
prophylactic antibiotics e.g. co-trimoxazole to prevent cholangitis
What is a choledochal cyst
Cystic dilatation of extra hepatic biliary system
How does choledochal cyst present
neonate: jaundice
older children: abdo pain, palpable mass, jaundice, cholagitis
How do you diagnose choledochal cyst
USS /MRCP
How do you treat choledochal cyst
surgical excision of cyst with Roux en Y anastomosis to biliary duct
What is neonatal hepatitis syndrome
Prolonged neonatal jaundice
Hepatic inflammation
LBW, faltering growth
What is Alagille Syndrome - clinical its
Rare autosomal dominan
Clinica fts:
- triangular facies
