What is shifting dullness test?

The shifting dullness test is a physical exam technique to detect ascites, or excess fluid in the abdomen, by listening for changes in percussion sounds as a patient moves, revealing fluid shifting from sides to the dependent area (like the flank) and then becoming resonant as air-filled bowels float up when the patient rolls over, indicating significant fluid (usually >500ml).

What does shifting dullness indicate?

A change in the level of dullness is termed shifting dullness and usually indicates more than 500 ml of ascitic fluid. Another physical sign of ascites is demonstration of a transmitted fluid wave. The patient or an assistant presses a hand firmly against the abdominal wall in the umbilical region.

How accurate is the shifting dullness test?

The positive predictive values of shifting dullness and prominent fluid waves were low (51% and 73%).

What is the most accurate test for ascites?

Traditionally, computed tomography has been regarded as the imaging modality of choice to demonstrate ascites and diagnose the underlying cause. However, ultrasound can reliably detect small volumes of fluid and is a useful first-line imaging modality for clinical triage.

How long to wait for shifting dullness?

Shifting dullness, present in ascites, should be demonstrated by percussing from the midline to the flank till the note changes from dull to resonant and then having the patient roll over on their side towards the examiner and wait for 10 seconds. This maneuver allows any fluid, if present, to move downwards.

Assessment for Abdominal Ascites

How to tell if a horse is using the hind end?

To determine if your horse is engaged, look at the articulation and the activity of the hind end and whether that energy is transmitted through an elastic back toward the bit. Engagement should feel like the horse propels you without effort.

What are the 5 F's of ascites?

The traditionally taught five causes of generalised abdominal distension (the 'five Fs') are: flatus, fluid, faeces, fetus and fat. To this list should be added a sixth: massive organomegaly or 'filthy big tumour'.

What confirms ascites?

Diagnosing ascites involves a physical exam (checking for swelling, dullness, fluid thrill), blood tests (liver/kidney function, SAAG), and imaging like ultrasound or CT to confirm fluid and assess the liver. A key step is paracentesis, where a needle draws fluid for analysis (cell count, cytology, SAAG, cultures) to find the cause, often cirrhosis, heart failure, kidney issues, or cancer.
 

What can be confused with ascites?

Many people confuse abdominal fat with ascites because both cause a swollen belly. But the difference between ascites and belly fat can be the difference between a harmless condition and a serious medical issue.

What medication is used for ascites?

Firstline treatment of ascites should be spironolactone alone, increasing from 100 mg/day to a dose of 400 mg/day. If this fails to resolve ascites, frusemide should be added in a dose of up to 160 mg/day, but this should be done with careful biochemical and clinical monitoring.

What is the confirmatory test for ascites?

A diagnosis of ascites is suspected on the basis of history and physical examination, but the final confirmation is based on successful abdominal paracentesis. Sampling ascitic fluid in all patients with new-onset ascites is necessary.

What stage of liver disease is ascites?

Ascites, the buildup of fluid in the abdomen, signals a progression to decompensated cirrhosis, which is the severe, late stage of liver disease, indicating the liver can no longer function adequately, leading to complications and a poorer prognosis. It's a key sign of end-stage liver disease (ESLD) and marks a significant milestone in the disease's natural history, often leading to other serious issues like portal hypertension.
 

What are the red flags for abdominal assessment?

Other red flags include:

Abdominal distension. Bilious (green) or blood-stained vomit. Blood in stool. Palpable abdominal mass.

What are four signs of peritonitis?

They may include:

• Severe belly pain that gets worse with any motion.
• Nausea and vomiting.
• Fever.
• Sore or swollen belly.
• Fluid in the belly.
• Not being able to have a bowel movement or pass gas.
• Less urine than normal.
• Thirst.

What cancers commonly cause ascites?

Certain cancers, such as ovarian, pancreatic, liver, and colon cancers, are more likely to cause ascites. What Are the Symptoms and Complications of Ascites? Patients can experience swelling and tightness of the abdomen, feeling full when eating, nausea, or shortness of breath.

What is the main cause of fluid in the abdomen?

The most common cause of ascites is cirrhosis of the liver. Drinking too much alcohol is one of the most common causes of cirrhosis of the liver. Some types of cancer, like ovarian or bladder cancer, can also cause it. Ascites caused by cancer most often occurs with advanced or recurrent cancer.

What is the best test for ascites?

The best tests for ascites start with abdominal ultrasound for quick, accurate fluid detection, followed by a paracentesis (fluid withdrawal) for analysis, which is crucial for finding the cause, often using the Serum-Ascites Albumin Gradient (SAAG) to check for portal hypertension. A physical exam, blood/urine tests, CT/MRI scans also help determine underlying liver/kidney issues. 

Which virus causes ascites?

Infection With the Hepatitis A Virus Associated With Ascites in Children.

How does your body get rid of ascites?

Water tablets (diuretics)

Your doctor may give you a water tablet (diuretic), such as spironolactone. This may help the body get rid of excess fluid as urine (pee). Your doctor or nurse might advise you to reduce the amount of salt in your diet. Taking a water tablet can help slow the build-up of the ascitic fluid.

What organ failure causes ascites?

Ascites (ay-SITE-eez) is when too much fluid builds up in your abdomen (belly). This condition most often happens in people who have cirrhosis (scarring) of the liver.

What is the 1/2/3 rule in horses?

Post Parturition Guidelines: The 1-2-3 Rule The foal should stand within one hour of delivery, nurse within two hours, and the placenta should pass within three hours. If there are any delays, a call to your veterinarian is crucial, as this is a critical time for the mare and foal.

How does a horse say "I love you"?

Much like other pets, horses use licking as a way to show their love! Breathing on you, licking, and kissing are all ways a horse may be trying to tell you how much you mean to them. They also may grasp you with their lips to pull you in, and then lick.

What are the first signs of EPM in a horse?

The first signs of EPM in horses are often subtle and vague, including mild incoordination (ataxia), asymmetric muscle wasting (atrophy), mild lameness, or strange gait, easily mistaken for other issues like injury, but also can present as head tilt, difficulty eating/swallowing, or minor behavior changes. Early detection is crucial, so look for subtle one-sided weakness, stumbling, or muscle loss, especially in the hindquarters or topline.
