Assessment & Management of Hepatic Disorders Flashcards
How many lobes make up the liver?
Which one is larger?
What separates them?
Two lobes
Right is larger
Falciform ligament
How many different functions does the liver have?
Around 8 or so
What does the liver metabolize?
Carbs
Proteins
Fats
What does the liver store and filter?
The liver stores and filters blood.
What do the hepatocytes or liver cells make?
Bile
What form of glucose is stored in the liver?
What does the liver do when the glycogen is depleted?
Glycogen
Liver can convert protein and fat to glucose. This is called gluconeogenesis.
Which proteins are formed in the liver?
Plasma proteins.
Albumin is a big one for oncotic pressure.
But there are others:
globulin, prothrombin, fibrinogen, etc.
Which vitamins are stored in the liver?
B2, B6, B12
A, D, E, K, folic acid
What does bile contain that causes jaundice?
What does bile do to fat before it goes to intestines?
Bilirubin
Bile emulsifies the fat
What hormones does the liver have to do with?
Sex hormones
Aldosterone
Which enzyme stimulates gallbladder contraction, Oddi sphincter to open, and releases pancreatic juices all in order to secrete bile?
CCK-PZ
cholecystokin-pancroenzymin
What is ammonia converted to by the liver?
Urea
What are the liver serum enzyme labs we should pay attention to?
AST ALT GGT GGTP LDH
What other serum values should we look out for with the liver?
Ammonia Alkaline Phosphate Protein Bilirubin (urine as well tho) Creatinine & BUN
Other lab values?
Cholesterol Prothrombin time CBC WBC platelets
Why would they do a biopsy of the liver?
Cancer
What diagnostics could be done for the liver?
CT
MRI
EGD
TIPS or Transjugular intrahepatic portosystemic shunt (it helps relieve portal hypertension)
What side should we place the patient on if they are having hepatic pressure?
Their right side for hepatic issues.
What is Jaundice?
What substance is the cause of Jaundice?
Yellow/green colored body tissue & possible discoloration of the sclera or eyes. (could also be deep orange)
Bilirubin accumulation
Four types of Jaundice?
Hemolytic
Heptocellular
Intrahepatic obstruction
Hereditary hyperbilirubinemia
T/F
Immature kidneys cause jaundice in newborns.
False.
It is the immature LIVER that will cause this to occur in newborns.
Main cause of Hepatocellular Jaundice?
Damaged Liver cells cause Hepatocellular jaundice.
Hepatocellular Jaundice symptoms
How ill will they present?
What will their weight look like?
What will energy levels be like?
What will an infectious origin appear as?
Hepatocellular Jaundice:
They will present mild or severely ill.
Due to loss of appetite, they will appear thin.
They will be very tired and fatigued.
If infectious: headache, chills, and fever.
(Intrahepatic) Obstructive Jaundice Symptoms
UO appearance? Stool appearance?
GI symptoms?
Skin?
How to treat the jaundice?
Obstructive Jaundice:
UO orange-brown in color. Stool is clay colored.
GI will have impaired digestion; especially of fat.
Pruritus of the skin
Remove the stone
How can you help pruritus?
Warm bath or fan
Benadryl.. but pay attention to liver enzymes.
Topical meds are much better.
What is portal hypertension?
What does it contribute to?
High BP in veins that carry blood from intestines to liver
Ascites
Varices: rectal or esophageal. Up or down really.
Management of portal hypertension?
Not anti-hypertensives bc this is not a systemic problem.
Do re-routing with stents or correct underlying cause.
Ascites results from?
- The increased portal hypertension causing increased capillary pressure and and obstruction of venous blood.
- Aldosterone changes also increase retention of fluid.
- Albumin gets pulled into peritoneal cavity
How to monitor ascites?
Measure girth
Takes weight daily
Percuss and fluid shift checks
Monitor F&E
How to specifically treat ascites?
Diet
Meds
Activity
Procedure
Ascites Treatment:
Put them on a low sodium diet
Meds like Diuretics & salt poor albumin (they need to give them protein to improve oncotic pressure but not anymore salt)
Bedrest
Paracentesis, TIPS
What is a TIPS?
TIPS is an ascites procedure that can be done. Stands for transjugular intrahepatic portosystemic + shunt
Putting a stent in liver where the hepatic and portal veins connect in order to reroute the blood flow.
Placing the shunt decreases congestion.
What will ascites look like?
Striae (sort of like stretch marks)
Distended veins
Umbilical hernia from extra pressure
What are esophageal varices?
Essentially collateral circulation developing due to portal hypertension. Rupture and bleed easily.
Esophageal varices symptoms?
Esophageal varices symptoms:
Hematemesis (bleeding)
Melana (dark tarry stool)
Decrease BP – shock or vascular collapse can occur.
How to manage esophageal varices: give the explanation
Lavage?
Tamponade?
Shock complications?
Managing esophageal varices explanation:
Saline Lavage (taking fluids out or washing out something) or ice saline due to vasoconstriction
Balloon Tamponade to provide internal pressure
BUT the tissue is fragile so be aware of possible damage. Don’t leave in too long bc it can cause necrosis.
Shock can happen due to bleeding. Need to administer oxygen, IVF, and blood transfusions to return back to normal.
How to manage esophageal varices: give the explanation
Check VS
H&H
Cognitive status
Why might you check UO?
Maintain airway
Managing esophageal varices explanation:
Check Vitals for a good baseline especially since this involves someone possibly losing blood.
Check the H&H bc this lab is associated with blood loss
Alterations in cognition can indicate lack of perfusion to the cerebral areas.
UO is an indicator that the kidneys are at least being perfused.
Maintain the airway because with the tamponade, this is a balloon going down the esophagus. It can make breathing difficult for this with breathing patterns or anxiety. Can also make breathing hard if placed incorrectly.
You can reposition the patient, check the tubing, and GI suctioning if they need it.
How to manage esophageal varices: give explanation
Why might they give vasoconstricting medications?
Managing esophageal varices explanations:
Vasoconstriction meds help the varices constrict so that BP goes back up and control bleeding
Surgical methods for esophageal varices?
TIPS
Endoscopic sclerotherapy
Esophageal Band
Shunt
TIPS to reduce the portal hypertension that caused the varices in the first place
Endoscopic sclerotherapy will help stop bleeding by using a sclerosing agent.
Esophageal Banding cuts off blood flow.
Shunt is for drainage and decongesting
What is portal encephalopathy?
What dietary food group can make this worse?
Other problems that can occur?
Loss of neurological from liver not being able to remove ammonia and other toxins from the blood
Protein can make it worse.
all sorts of issues. Could have GI bleed or ascites
Neurological symptoms to look for with portal encephalopathy?
Confusion
Lethargic
LOC alterations
