Ascites Flashcards
What i the pathophysiology behind ascites
Increased portal htn increases hepatic resistance, increased portal pressure, vasodilation of splanchnic arteries, increase in portal venous inflow. The hemodynamic changes result in an increase in Na retention by activation of RAAS and hyperaldosteronism. Retained fluid leaks out into peritoneal cavity. Reduction in albumin and oncotic pressure increases the problem.
What is the most common cause of ascites
Portal htn
Symptoms of ascites
Increased abdominal girth, SOB, hepatothorax, malnourished, fatigue, weakness, muscle wasting
Diagnostics for ascites
Physical exam, abdominal fluid shift
CXR: hepatothorax
Diagnostics for ascites
Physical exam
ABD imaging
CXR: hepatothorax
Treatment for minimal, moderate, and severe ascites
Minimal: Na restriction
Moderate: Aldactone or lasix
Severe: Refractory to other treatments, will need repeat paracentesis, possible TIPS procedure
