Blunt Force Trauma

Although the liver is the most frequently injured abdominal organ, the spleen is the most frequently injured intra-abdominal organ from sports accidents.

• YES

• NO

Compressive, shearing or stretching, and acceleration/deceleration forces impact the abdominal cavity and structures leading to abdominal wall, solid

organ, or hollow viscous injuries.

• YES

• NO

Regarding abdominal trauma, please Mark the FALSE option.

• The most common mechanism for blunt abdominal trauma is a motor vehicle collision.

• Gunshot wounds create secondary missiles such as fragmented bone that may increase the traumatic

  burden.

• Young, healthy patients are not able to compensate for intra-abdominal hemorrhage before clinical signs become overt.

• Clinical signs may be obvious (such as evisceration) or occult.

In blunt abdominal trauma, the incidence of blunt bowel and mesenteric injuries is frequent.

• YES

• NO

The underlying premise of the FAST exam is that many clinically significant injuries will be associated with free intraperitoneal fluid.

• YES

• NO

Regarding FAST in abdominal trauma, one of this options is FALSE, please mark it:

• The FAST examination is accurate, rapid, noninvasive, repeatable, and portable, and involves no nephrotoxic contrast material or ionizing radiation.

• Massive hemoperitoneum is quickly detected with a single view of Morison’s pouch.

• The main advantage of US compared to CT is the ability to identify the exact source of free intraperitoneal fluid.

• FAST also evaluates for free pericardial or pleural fluid and for

  pneumothorax.

Regarding CT in abdominal trauma, please mark the FALSE option:

• Abdominopelvic CT with IV contrast is the invasive gold standard study for the evaluation of abdominal injury .

• The major advantage of IV contrast CT over other diagnostic modalities is that the precise location(s) of specific injury can be identified.

• CT can quantify and differentiate the amount and type of free fluid in the abdomen.

• CT is the ideal study for assessment of the duodenum, pancreas, and vascular and renal systems.

Despite the reproducibility and prospectively validated sensitivity of Diagnostic Peritoneal Lavage (DPL) to diagnose intraperitoneal injury, the advent and acceptance of other diagnostic modalities have significantly reduced the frequency of DPL.

• YES

• NO
