What is an eFAST exam

E-FAST (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 included in a FAST scan?

Focused assessment with sonography for trauma (FAST) should include views of (1) the hepatorenal recess (Morison pouch), (2) the perisplenic view, (3) the subxiphoid pericardial window, and (4) the suprapubic window (Douglas pouch).

What is a positive eFAST scan?

Positive FAST will have one of the following: Anechoic area within the pericardial space. Anechoic areas between the liver and kidney. Anechoic areas between the diaphragm and spleen. Anechoic areas between the spleen and kidney.

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 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 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 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.

What is a negative FAST exam?

A negative FAST Exam does not have adequate sensitivity (especially in blunt Trauma) to reassure. A negative FAST Exam should not dissuade CT Abdomen or exploratory surgery in Abdominal Trauma.

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.

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.

What is ample trauma?

The mnemonic AMPLE (A llergies, M edications, P ast medical history, L ast meal or other intake, and E vents leading to presentation) is often useful as a means of remembering key elements of the history.

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?

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 B lines on ultrasound?

The A-line is a horizontal artifact indicating a normal lung surface. 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 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 is the rectouterine pouch?

The rectouterine pouch is a bag-shaped extension of the peritoneum. … The rectouterine pouch is the lowest point of the abdominal cavity. In women, it is situated between the rectum and the uterus; in men, between the rectum and the bladder.

Is it normal to have no fluid in the pouch of Douglas?

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.

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.

Is flail chest life threatening?

Prognosis and outlook. Immediate treatment for flail chest is required to prevent it from threatening your life. It’s an extremely serious condition. Younger people who are in good health can usually recover without experiencing further complications, if the correct treatment is administered promptly.

Which organ is most likely to be injured blunt trauma?

Blunt abdominal trauma usually results from motor vehicle collisions (MVCs), assaults, recreational accidents, or falls. The most commonly injured organs are the spleen, liver, retroperitoneum, small bowel, kidneys (see the image below), bladder, colorectum, diaphragm, and pancreas.

What causes blunt chest trauma?

Blunt chest trauma is usually caused by motor vehicle accident, falling from height, blunt instrument injury and physical assault. As a result of chest trauma, many injuries may occur, such as pulmonary injuries, and these require urgent intervention.

How is peritoneal lavage performed?

Peritoneal lavage is a bedside procedure for evaluating bleeding in the abdominal cavity or a ruptured organ. In this procedure, a needle connected to a catheter, a tube-like structure, is inserted into your abdominal cavity. It is commonly known as diagnostic peritoneal lavage (DPL).

What is peritoneal toilet?

lized material from the peritoneal cavity. Although “peritoneal toilet” is a more. general term that refers to any method that cleans out the peritoneal cavity, such. as placement of a drain, the terms “debridement” and “toilet” will be used inter- changeably.

Listen to pronunciation. (PAYR-ih-toh-NEE-ul WAH-shing) A procedure in which a salt-water solution is used to wash the peritoneal cavity and then is removed to check for cancer cells. The peritoneal cavity is the space in the abdomen that contains the intestines, stomach, and liver.

What ultrasound interaction causes B lines?

In the presence of extravascular lung water (EVLW), the ultrasound beam finds subpleural interlobular septa thickened by edema. The reflection of the beam creates some comet-tail reverberation artifacts, called B-lines or ultrasound lung comets.

What does free fluid on ultrasound look like?

Collections of peritoneal free fluid appear black, or anechoic, on ultrasound imaging. Although ultrasound is sensitive to detect small amounts of peritoneal free fluid, it cannot accurately differentiate types of peritoneal free fluid.

Can I eat before an 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.
