eFAST – extended focused assessment with sonography in trauma.

When do you use eFAST?

1. Blunt and/or penetrating abdominal and/or thoracic trauma.
2. Undifferentiated shock and/or hypotension (as part of the Rapid Ultrasound for Shock and Hypotension (RUSH) exam).

What is a major benefit of FAST or eFAST?

The benefits of the FAST examination include the following: Decreases the time to diagnosis for acute abdominal injury in BAT. Helps accurately diagnose hemoperitoneum. Helps assess the degree of hemoperitoneum in BAT.

What is a positive eFAST scan?

Positive EFAST will have one of the added pulmonary findings: Anechoic area above the diaphragm between the diaphragm and lung. Absent lung sliding – lack of lung rockets seen under the pleural line.

How much fluid is needed for a positive FAST?

The volume of free fluid necessary to enable detection with FAST represents a limitation of FAST . Branney and colleagues determined that the mean minimum detectable free-fluid volume during FAST examination in 100 patients undergoing DPL was 619 mL in the Morison pouch (24).

What is lung sliding?

Lung sliding is the respirophasic shimmering to and fro movement of the visceral and parietal pleural surface. The presence of lung sliding indicates that the lung is fully inflated at the site of probe placement on the chest wall, so there is no pneumothorax at that examination site.

What is a limitation of a FAST exam?

The main limitation of the FAST examination is that the operator must be knowledgeable in its clinical use and be aware that it does not exclude all injuries. Limitations to the pericardial assessment for hemopericardium include pericardial fat pads, cysts, and preexisting pericardial fluid.

What is FAA eFAST?

eFAST is the FAA’s preferred contracting vehicle for small business contracts. eFAST streamlines the procurement process for all stakeholders using a web-based acquisition tool and automated workflows that are compliant with FAA standards. … Any FAA Program Management Office and Contracting Officer can use eFAST.

What is FAST medical?

The acronym FAST (Facial drooping, Arm weakness, Speech difficulties and Time) has been used by the National Stroke Association, American Heart Association and others to educate the public on detecting symptoms of a stroke. FAST was first introduced in the United Kingdom in 1998.

What is Morsion and Douglas pouch?

Morison’s pouch is an area between your liver and your right kidney. It’s also called the hepatorenal recess or right subhepatic space. Morison’s pouch is a potential space that can open up when fluid or blood enters the area. When these aren’t present, there’s no space between your liver and right kidney.

Which injury is associated with asymmetric movement in the lower chest wall?

Observe the lower chest for asymmetric chest wall movement, which may indicate lower rib fractures and liver, spleen or diaphragmatic injury.

What is diagnostic peritoneal lavage and why?

Diagnostic peritoneal lavage (DPL) is an invasive emergency procedure used to detect hemoperitoneum and help determine the need for laparotomy following abdominal trauma. A catheter is inserted into the peritoneal cavity, followed by aspiration of intraperitoneal contents, often after their dilution with crystalloid.

Which laboratory test is considered the best indicator of a pancreatic injury?

CT scanning In a patient who is hemodynamically stable, a CT scan provides the safest and most comprehensive means of diagnosis of pancreatic injury.

Which organs are injured most frequently?

The most commonly injured organs are the spleen, liver, retroperitoneum, small bowel, kidneys (see the image below), bladder, colorectum, diaphragm, and pancreas. Men tend to be affected slightly more often than women. Blunt abdominal trauma. Right kidney injury with blood in perirenal space.

Which injury causes decreased cardiac output?

Decreased cardiac output can be caused by the following: Heart failure. Pulmonary embolus. Acute myocardial infarction.

Can FAST detect retroperitoneal bleeding?

The FAST exam cannot reliably evaluate the retroperitoneal space. Treatment for retroperitoneal bleeding escalates with a worsening clinical presentation from nonoperative management to angioembolization to surgical intervention. The retroperitoneal zones determine management in traumatic retroperitoneal bleeding.

Why do a FAST exam?

Current indications for performing a FAST examination include blunt and penetrating cardiac and chest trauma, trauma in pregnancy, pediatric trauma, undifferentiated hypotension, and even evaluation of medical (non-trauma) patients for ascites.

Do you need to fast for abdominal ultrasound?

You typically need to avoid food and drinks (fast) for eight to 12 hours before an abdominal ultrasound. Food and liquids in your stomach (and urine in your bladder) can make it difficult for the technician to get a clear picture of the structures in your abdomen.

What is DPL in trauma?

One procedure used to determine whether blunt trauma victims require surgery is diagnostic peritoneal lavage (DPL). DPL helps determine whether an intra-abdominal injury exists and whether surgery is required. Using local anesthesia, the surgeon makes a small incision in the abdomen just below the umbilicus.

What is a lung pulse?

Lung pulse is the cardiophasic movement of the visceral parietal pleural surface (arrow). The presence of lung pulse indicates that the lung is fully inflated at the site of probe placement on the chest wall, so there is no pneumothorax at that examination site.

What do B lines mean?

The B-line is a kind of comet-tail artifact indicating subpleural interstitial edema. The relationship between anterior interstitial edema detected by lung ultrasound and the pulmonary artery occlusion pressure (PAOP) value was investigated.

What are B lines on ultrasound?

B lines, previously termed ”comet tails,” are vertical hyperechoic reverberations moving synchronously with the lung and represent key artifacts in interpreting pulmonary ultrasound findings [3,4]. The physiologic basis of B lines relates to decreased lung aeration [5], a finding that is nonspecific.

What are the early warning signs of a stroke?

• Weakness or numbness of the face, arm or leg, usually on one side of the body.
• Trouble speaking or understanding.
• Problems with vision, such as dimness or loss of vision in one or both eyes.
• Dizziness or problems with balance or coordination.
• Problems with movement or walking.
• Fainting or seizure.

What are the 5 warning signs of a stroke?

• Sudden numbness or weakness in the face, arm or leg (especially on one side of the body).
• Sudden confusion or trouble speaking or understanding speech.
• Sudden vision problems in one or both eyes.
• Sudden difficulty walking or dizziness, loss of balance or problems with coordination.

Why is a stroke called a stroke?

The hole in the artery wall means blood flow is reduced farther downstream. That causes blood to spill into the tissue surrounding the artery. Any time blood flow to a part of the brain is disrupted, the event is called a stroke.

What is strategic sourcing vehicles?

SSPO FAQs. Strategic sourcing is a collaborative and structured process of critically analyzing an organization’s procurement spend and using this information to make business decisions about acquiring and managing commodities and services more effectively and efficiently.

What is the FAA Saves contract?

The FAA-SAVES contract is the Federal Aviation Administration’s (FAA) method around Strategic Sourcing for the Acquisition of Various Equipment and Supplies (SAVES). The contract revolves around upgrading and smoothing out setups for government contracting IT equipment and expert administrations.

What causes ascites?

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. Different types of cancer can also cause this condition. Ascites caused by cancer most often occur with advanced or recurrent cancer.

What does minimal ascites mean?

‘Minimal’ ascites was defined, when the volume of ascites was estimated to be less than 50 mL, and ascites of 50-300 mL was defined as ‘mild’.

What does fluid in pouch of Douglas mean?

A small amount of fluid in the cul-de-sac is normal. But if the sample shows signs of pus or blood, the area may need to be drained. Blood in the fluid could mean a cyst has ruptured or there is a tear. It could also be a sign of an ectopic pregnancy. Pus could mean you have an infection.
