16
Q

what is TIPS and when should it be offered

A

Transjugular intrahepatic portocystemic shunt

offered after giving terlipressin & band ligation of varices

17
Q

mechanism of terlipressin

A

synthetic vasopressin analogue. causes vasoconstriction of vessels in splanchnic circulation –> reducing portal pressure

18
Q

adverse effects of terlipressin

A
  • low cardiac output
  • AF
  • MI
  • HF
  • GI upset
  • low sodium
19
Q

3 steps of progression of alcohol affecting liver

A

1) Alcohol related fatty liver
2) Alcoholic hepatitis
3) Cirrhosis

20
Q

what is recommended alcohol consumption

A

no more than 14 units in a week, should be spread evenly over 3 days or more
& no more than 5 units a day

21

Q

signs of liver disease

  • spider naevi
  • ascites
  • capat medusae
  • asterixis
  • palmar erythema
  • gynaecomastia
  • bruising
24
Q

markers for reduced synthetic function of the liver

A

low albumin

elevated prothrombin time

25
Q

when do alcohol withdrawal symptoms begin to occur and what are these

A

6-12 hours

tremor, sweating, headache, craving, anxiety

26
Q

at what time frame of alcohol withdrawal do hallucinations and seizures occur

A

12-24 hours: hallucinations

24-48 hours: seizures

27
Q

what time frame does ‘delirium tremens’ tend to occur at

A

24-72 hours after abstaining from alcohol consumption

28
Q

mechanism of action of alcohol withdrawal causing delerium tremens

A

Alcohol Stimulates GABA receptors & inhibits glutamate receptors. therefore in chronic alcoholics the GABA system is upregulated & Glutamate receptors are downregulated

in alcohol withdrawal, GABA under functions & glutamate overfunctions –> causing extreme excitability of the brain with excess adrenergic activity

29
Q

presentation of delerium tremens

A
  • acute confusion
  • severe agitation
  • delusions/hallucinations
  • tremor
  • tachycardia
  • HTN
  • ataxia
  • arrhythmia
30
Q

management of alcohol withdrawal

A

chlordiazepoxide (Librium)

31
Q

3 features of wernicke’s encephalopathy

A
  • confusion
  • ataxia
  • occulomotor disturbances
32
Q

what can wernicke’s encephalopathy progress into

A
Korsakoff syndrome 
(memory impairment &amp; behavioural changes)
33
Q

management of wernickes encephalopathy

A

Thiamine (Vit B1)
