  4. Sepsis (pneumonia / septicaemia)
  5. Hypoglycaemia
23
Q

What are the CF of Portal HTN (complication of Cirrhosis)? (4 things)

Study These Flashcards
A
  1. Oesophageal varices
  2. Splenomegaly
  3. Ascites
  4. Caput medusae (periumbilical vein dilation)
24
Q

Where does the Portal Vein come from? (2 things)

Study These Flashcards
A
  1. Superior mesenteric vein

2. Splenic vein

25
Where does the Portal Vein deliver blood to?
Liver
26
How does Portal HTN cause Varices in Cirrhosis? (4 steps)
1. Fibrosis affects blood flow thru liver 2. This increases resistance of blood flow in liver 3. Increased back-pressure into Portal System --> Portal HTN 4. Vessels where Portal System anastomoses w Systemic Venous System become Swollen = Varices
27
Where do Varices in Cirrhosis occur? (4 locations)
1. Gastro-Oesophageal junction 2. Anterior abd wall via umbilical vein (Caput Medusae) 3. Ileocaecal junction 4. Rectum
28
When do Varices cause symptoms or problems?
Only when they start bleeding, which is common bc high blood flow thru them
29
What are the treatment options for Stable Varices in Cirrhosis? (4 things)
1. Propranolol (reduced Portal HTN) 2. Elastic band ligation of Varices 3. Injection of Sclerosant (less effective than band ligation) 4. Transjugular Intra-Hepatic Portosystemic Shunt (TIPS) (done by interv. radiologist)
30
How should a pt w bleeding Oesophageal Varices be managed? (2 things)
1. Resus | 2. Urgent endoscopy
31
How should a pt w bleeding Oesophageal Varices be Resuscitated? (4 things)
1. Vasopressin analogies (cause vasoconstriction --> slow bleeding) 2. Vit K + Fresh Frozen Plasma (correct coagulopathy) 3. Prophylactic Broad spec Abx 4. Consider intubation / ICU
32
What is done in Urgent Endoscopy of bleeding Oesophageal Varices in Cirrhosis? (2 things)
1. Sclerosant injected (causes inflammatory obliteration of vessel) 2. Elastic band ligation
33
How does Ascites happen in Cirrhosis? (2 steps)
1. Increased pressure in Portal System | 2. Fluid leaks out of capillaries in liver + bowel --> Peritoneal Cavity
34
How does Ascites from Cirrhosis affect the kidney? (5 steps)
1. Fluid loss into Peritoneal cavity --> drop in circulating volume 2. Drop in circulating volume --> reduction in BP entering kidneys 3. Kidney sense low BP --> release Renin 4. Renin --> causes Aldosterone secretion (via RAAS system) 5. Renin --> reabsorbtion of fluid + Na in kidneys
35
How should Ascites from Cirrhosis be managed? (5 things)
1. Low sodium diet 2. Diuretics (e.g spironolactone) (to oppose aldosterone) 3. Paracentesis (drain fluid) 4. Prophylactic abx (vs Spontaneous Bacterial Peritonitis) 5. Consider TIPS / transplant
36
What is Spontaneous Bacterial Peritonitis?
Infection dev in Ascites fluid + Peritoneal lining
37
What are the CF of Spontaneous Bacterial Peritonitis? (6 things)
1. Can be asymptomatic 2. Fever 3. Abd pain 4. Deranged bloods (raised WBC, CRP, Creatinine) 5. Ileus (lack of movement in intestines) 6. Hypotension
38
What is the most common organism that causes Spontaneous Bacterial Peritonitis?
E. coli
39
How is Spontaneous Bacterial Peritonitis managed? (2 things)
1. Take ascitic culture before abx | 2. IV cephalosporin
40
Why does Malnutrition / Muscle wasting happen in Cirrhosis? (2 steps)
1. Cirrhosis --> reduces protein available / synth. | 2. Body uses muscle tissue as fuel
41
How does Cirrhosis lead to reduced protein available? (2 things)
1. Reduced protein produced in liver | 2. Reduced protein available for muscle growth
42
Why does the body use muscle tissue as fuel in Cirrhosis?
Cirrhosis disrupts the ability for liver to store glucose as Glycogen and release it when needed
43
What is the management of Malnutrition / muscle wasting in Cirrhosis? (4 things)
1. Reg meals (every 2-3 hrs) 2. Low sodium diet (to min. fluid retention) 3. High prot + calories 4. Avoid alcohol
44
How does Hepatorenal Syndrome happen in Cirrhosis? (8 steps)
1. Increased pressure in Portal System 2. Fluid leaks out of capillaries in liver + bowel --> Peritoneal Cavity 3. Fluid loss into Peritoneal cavity --> drop in circulating volume 4. Drop in circulating volume --> reduction in BP entering kidneys 5. Kidney sense low BP --> release Renin --> activates RAAS system 6. RAAS system --> Renal vasoconstriction 7. Renal vasoconstriction + low circ volume = blood starvation of kidney 8. Leads to rapidly deteriorating kidney
45
How long does it take for Hepatorenal Syndrome to kill you?
1 week
46
What is the treatment for Hepatorenal Syndrome?
Liver transplant
47
How does Cirrhosis cause Hepatic Encephalopathy?
Cirrhosis causes ammonia build up --> ammonia = toxin that affects brain
48
Why does Ammonia build up in Cirrhosis? (2 things)
1. Functional impairment of liver cells --> X metabolise ammonia into harmless waste products 2. Collateral vessels between Portal n Systemic circ --> ammonia bypasses liver --> ammonia enters systemic system directly
49
What are the precipitating factors for Hepatic Encephalopathy? (6 things)
1. Constipation 2. Elec imb 3. Infection 4. GI bleed 5. High prot diet 6. Sedative meds
50
What are the CF of Hepatic Encephalopathy? (6 things)
1. Confusion + Coma 2. Drowsiness 3. Fetor hepaticus (stanky breath) 4. Hyperventilation 5. Asterexis 6. Changes in personality n memory n mood (CHRONICALLY)
51
How should you manage a pt with Hepatic Encephalopathy? (3 things)
1. Laxatives (e.g lactulose) (to promote ammonia excretion) 2. Abx (e.g rifaximin) (reduces number of intestinal bac producing ammonia) 3. Nutritional support (may need NG feeding)
