ascitic fluid

Testing for fluid wave

ask patient or assistant to press edges of both hands firmly down midline of abdomen. this pressure helps to stop the transmission wave through fat. while you tap one flank sharply with your fingertips, feel on opposite flank for impulse transmitted through fluid. unfortunately this sign is often negative until ascites is obvious and is sometimes positive in people without ascites

This pain is felt in more distant sites which are innervated at approximately the same spinal levels as the disordered structures.

Referred pain

This type of pain often develops as the initial pain becomes more intense and seems to radiate or travel from the initial site. It may be palpated superficially or deeply but is usually localized

Referred pain

Percuss the abdomen where and what should you hear?

all 4 quadrants, liver (midclavicular line from umbilicus and nipple line) and splenic (lowest interspace, anterior axillary line) margins; should hear mostly tympany due to gas in the GI tract but scattered areas of dullness from fluid and feces are common.

Distention may be localized or generalized. Causes tympanitic percussion note. Selected foods may cause mild distention from increased intestinal production of this. More serious causes are intestinal obstruction and paralytic ileus. Note location of distention. If more marked, obstruction in colon more likely vs small bowel.

Gas

Postexposure prophylaxis Hepatitis A

Healthy unvaccinated should receive Hep A vaccine or single dose immune globulin (preferred for age >40) within 2 weeks of exposure (applies to close personal contact of those with confirmed dx)

When RUQ pain and tenderness suggest cholecystitis, assess for what sign

Murphy

This is a steady, aching pain that is usually more severe than visceral pain and more precisely localized over the involved structure. It is typically aggravated by movement or coughing. Patients typically prefer to lie still.

Parietal pain

This type of pain originates from inflammation of the parietal peritoneum, called peritonitis

Parietal pain

Explain the progression of appendicitis pain

Periumbilical pain from distention of an inflamed appendix which gradually changes to parietal pain in the RLQ from inflammation of the adjacent parietal peritoneum

Tenderness associated with this is more severe than visceral tenderness. Muscular rigidity and rebound tenderness are frequently but not necessarily present. If generalized causes exquisite tenderness throughout the abdomen, together with board like muscular rigidity. Signs on palpation especially abdominal rigidity double likelihood of this

Tenderness of peritoneal inflammation

Mucosal inflammation typically extending proximally from the rectum (proctitis) to varying lengths of the colon (colitis to pancolitis) with microulcerations and if chronic inflammatory polyps

UC

Cramping with urgency, tenesmus fever, fatigue, weakness, abdominal pain if complicated by toxic megacolon; may include episcleritis, uveitis, arthritis, erythema nodosum VS Cramping periumbilical right lower quadrant or diffuse pain with anorexia, fever, and or weight loss, perianal or peri rectal abscess and fistulas may cause small or large bowel obstruction

UC; Crohn's

Which inflammatory bowel disease will cause frequent watery and bloody stools vs small soft to loose or watery stools with bleeding or obstructive sx

UC; Crohns

Best method for determining hepatomegaly

US

Acute abdominal processes in the older adult as far as signs and sx

aging often blunts manifestations of acute abdominal disease. pain may be less severe, fever often less pronounced, signs of peritoneal inflammation such as guarding and rebound tenderness may be diminished or even absent

When does a GERD patient warrant endoscopic evaluation

Uncomplicated GERD that fails empiric therapy, age >55 years, and "alarm" sx

Ischemia stimulates this pain

Visceral pain

This pain occurs when hollow abdominal organs such as intestine or biliary tree contract unusually forcefully or are distended or stretched. Solid organs such as the liver can also become painful when their capsules are stretched. This pain may be difficult to localize. It is typically palpable near the midline at levels that vary according to structure involved.

Visceral pain

This type of pain varies in quality and may be gnawing, burning, cramping, or aching. When it becomes severe, sweating, pallor, nausea, vomiting and restlessness may follow

Visceral pain

Usually this discomfort is dull with no muscular rigidity or rebound tenderness

Visceral tenderness

Why is it important to ask about the color of stool with jaundice?

When excretion of bile into intestine is completely obstructed, stools become gray or light colored or acholic without bile

Abdominal changes in the older adult

abdominal muscles tend to weaken decreased activity of lipoprotein lipase and fat may accumulate in lower abdomen and near hips even if weight stable-this change in abdominal fat distribution increases risk of CVD. changes often produce softer more protruding abdomen which patients may interpret as fluid or evidence of disease

Confined inflammatory process usually in LLQ that involves sigmoid colon. If sigmoid colon is redundant, there may be suprapubic or right sided pain. Look for peritoneal signs and a tender underlying mass. microperforation abscess and obstruction may ensue

acute diverticulitis

LLQ pain with cramping, steady pain with gradual onset. May have associated fever, constipation, nausea, vomiting, abdominal mass with rebound tenderness

acute diverticulitis

May children present with abdominal pain from ? Despite pain,physical exam is relatively normal except for increased bowel sounds on auscultation and mild tenderness on palpation

acute gastroenteritis

Abdominal pain and tenderness may result from this. When unilateral, can mimic acute cholecystitis or appendicitis. Rebound tenderness and rigidity are less common; chest signs usually present

acute pleurisy

This is a strikingly yellowish discoloration of the skin and sclerae from increased levels of bilirubin, a bile pigment derived chiefly from the breakdown of hemoglobin. Normally hepatocytes conjugate unconjugated bilirubin with other substances making the bile water solube, and then excrete the conjugated bilirubin into the common bile duct which also drains the extrahepatic ducts from the liver. More distally, the common bile duct and the pancreatic ducts empty into the duodenum at the ampulla of vater.
