Abdominal cavity
Abdominal cavity is divided into what two regions?
Peritoneal cavity
Retroperitoneal space
“True Abdomen”
- Solid organs
- Portions of the large intestine
- Most of the small intestines
- Female reproductive organs
Peritoneal cavity
Area located behind the peritoneum and contains:
- Kidneys
- Ureters
- Inferior vena cava
- Aorta
- Pancreas
- Much of the duodenum
- Ascending descending colon and rectum
Retroperitoneal
The acids, enzymes and bacteria from the GI tract in an injury can result in:
Peritonitis and sepsis
Most commonly injury:
- Small bowel (50%)
- Colon (40%)
- Liver (30%)
- Abdominal vessels (25%)
GSW
___% of GSW will require surgery for definitive intervention
85%
__% of stab wounds will require surgery for definitive intervention
15%
Injuries most often involved in blunt abdominal trauma include
- Spleen 40-55%
- Liver 35-45%
- Small bowel 5-10%
The most reliable indicator of intra-abdominal bleeding is the:
Presence of hypovolemic shock from an unexplained source
Indicates sudden force from deceleration (20% chance of intra-abd injury in adults) bowel
Seat Belt Sign
Distended abdomen may result from greater than ___ L of blood or a stomach filled with air
1.5 L
Historically thought to be a strong indicator of peritonitis. Controversial – performed by deeply palpating then quickly releasing. If more pain is felt when releasing then this is a positive test.
Rebound tenderness
Auscultation
Hemorrhage or spillage of contents may result in:
Ileus (cessation of peristalsis)
Bowel sounds are heard over the thorax
Diaphragmatic injury
