Hepatic jaundice in the context of cardiac failure arises due to impaired liver blood flow, leading to hepatic congestion and subsequent liver dysfunction. When the heart cannot effectively pump blood, it causes increased pressure in the hepatic veins, resulting in hepatocyte damage and impaired bilirubin processing. This dysfunction leads to the accumulation of bilirubin in the blood, manifesting as jaundice. Additionally, reduced hepatic perfusion can impair bile production and excretion, further contributing to the jaundiced appearance.
What else can I help you with?
Why does urine becomes dark in post hepatic jaundice?
Due to bilirubin buildup in the urine
Does any hepatic failure produce jaundice?
Mostly yes, since the necrosis of hepatocytes (liver cells), decreases the ability of the liver to process bilirubin produced from hemoglobin breakdown when RBCs die. Thus, it can accumulate in the blood stream and give rise to jaundice.The severity of jaundice depends on the extent of liver damage.
Liver cirrhosis with hepatic encephalopathy nursing care plan?

What is the treatment for pre-hepatic jaundice?

What is post-hepatic jaundice and how is it caused?
Post-hepatic jaundice, also known as obstructive jaundice, occurs when there is an obstruction in the bile ducts preventing bile from flowing from the liver to the intestine. This obstruction can be caused by conditions such as gallstones, tumors, or strictures in the bile ducts. As a result, bilirubin accumulates in the bloodstream, leading to the yellowing of the skin and eyes characteristic of jaundice. Timely diagnosis and treatment are essential to relieve the obstruction and prevent complications.
What are the causes of hepatic jaundice?
Starvation, circulating infections, certain medications, hepatitis, and cirrhosis can all cause hepatic jaundice, as can certain hereditary defects of liver chemistry, including Gilbert's syndrome and Crigler-Najjar syndrome.
What is prehepatic Jaundice and posthepatic jaundice?
Jaundice is a condition where the skin turns yellow because of excess bilirubin in the bloodstream. It happens when your liver is not functioning properly, which can be due to a number of factors. Hepatitis is a virus which can cause liver disease, and thus cause Jaundice.
What is the difference between renal and hepatic circulation?
Renal circulation, receiving about 20% of cardiac output, branches from the abdominal aorta and returns to the ascending vena cava. Hepatic circulation is the system of veins made of the hepatic portal vein and its tributaries.
What is severe hepatic impairment?
Severe hepatic impairment refers to a significant reduction in liver function, typically classified as Child-Pugh Class C in the Child-Pugh scoring system. This condition can result from chronic liver diseases such as cirrhosis, hepatitis, or liver failure, leading to complications like jaundice, ascites, and coagulopathy. Patients with severe hepatic impairment often require careful monitoring and management, as their ability to metabolize drugs and toxins is greatly diminished, increasing the risk of adverse effects.
Why direct bilirubin increased in hepatic jaundice?
In hepatic jaundice, direct bilirubin levels increase due to impaired liver function, which affects the liver's ability to conjugate and excrete bilirubin. When liver cells are damaged or inflamed, such as in hepatitis or cirrhosis, they may not effectively process unconjugated bilirubin into its conjugated form. Consequently, both direct (conjugated) and indirect (unconjugated) bilirubin can accumulate in the bloodstream, leading to jaundice. The increase in direct bilirubin specifically indicates that the liver is attempting to process bilirubin but is unable to eliminate it adequately.
What is the pathophysiology of Anorexia and heart failure?
i think anorexia occure in HF due to portal and hepatic congestion
What does it mean liver parenchyma is homogeneous?
A homogeneous liver is one that has the same texture throughout.
