Evisceration

A

The displacement of organs outside of the body

Never try to replace an organ; Keep the organ moist and warm, cover the injury site with a large, sterile, moist, bulky dressing (and an occlusive dressing if specified by local protocol)

Q

Injuries to the kidneys

A

May be difficult to detect because they are located in a well-protected region; be alert for bruising or a hematoma in the flank region

Q

Treatment for sexual assault or rape

A

Treat for shock if necessary and record all facts in detail; follow any crime scene policy established in your system to protect the scene and evidence; advise the patient not to wash, bathe, shower, douche or void until a physician has examined them

Do not examine the genitalia of the victim unless obvious bleeding must be controlled

25
Organs of the Left Upper Quadrant (LUQ)
Spleen and stomach, pancreas (mostly posterior region)
26
Organs of the Left Lower Quadrant (LLQ)
Large and small intestines, notably the descending colon and L half of the transverse colon
27
Organs of the Right Lower Quadrant (RLQ)
Appendix, large and small intestines, notably the ascending colon and R half of the transverse colon
28
Appendix rupture
Severe infection and septic shock may occur
29
Peritonitis
Caused by the leaking of stomach and/or intestinal fluids to the peritoneal cavity. May become life threatening First signs are severe abdominal pain, tenderness and muscular spasm; Later signs are diminished bowel sounds or function; nausea, vomiting, abdomen may be become distended
30
Small intestines
Duodenum, jejunum, ileum
31
Large intestines
Cecum, colon, rectum
32
Mesentery
Supplies blood to the intestines; a fold of tissue containing vessels, nerves and lymphatic tissues; it connects the small intestine to the posterior of abd. wall
33
Retroperitoneal region
Where many solid organs, great vessels, abdominal aorta, inferior vena cava, kidneys, ureters, pancreas and bladder are housed
34
Compression injuries
Typically caused by a poorly placed seatbelt; creates a pattern called a clasp-knife injury, an exaggerated resistance of muscles, resembling the opening of a penknife or clasp knife Can also be caused when a person is run over or rolled over
35
Deceleration injuries
Commonly occur when a person or vehicle the person is in strike a large immovable mass
36
Injury to the liver and spleen, and bleeding into the peritoneal space can result in pain that is
Pain is often referred (transferred) to the shoulder and can easily be overlooked
37
An abdominal aneurysm that is dissecting can result in pain that is
Tearing pain and describes it as going from the abdomen posteriorly
38
Damage to the kidneys or ureters can result in pain that is
Pain that is following the angle from the lateral hip to the midline of the groin
39
An inflamed or ruptured appendix can result in pain that is
Pain primarily located in the RLQ
40
Direct injury or inflammation of the gallbladder can result in pain that is
Pain that can be found just under the margin of the ribs on the right side or between the shoulder blades
41
Acute pain in the entire abdomen is
A common response to blood and fluid from damaged organs flowing into the peritoneal cavity; rebound tenderness may occur if exposed to any jarring motion
42
Abdominal distention or swelling between the xiphoid process and groin is often the result of
Free fluid, blood or organ contents spilling into the peritoneal cavity May also be the result of air or gases in the bowel or from infection
43
Lower rib fractures
If trauma was forceful enough to break ribs, it may have damaged internal organs
44
Because it make take several minutes to hours for contusion or hematoma to become present
Do not rule out serious abdominal injury based on the absence of bruising or discoloration
45
When worn properly, the seatbelt sits
Below the anterior superior iliac spines of the pelvis and against the hip joints
46
If a seatbelt is too high
It can squeeze abdominal organs or great vessels against the spine when the vehicle suddenly decelerates; occasionally fractures to the lumbar spine may occur
47
This anatomic change allows the normally protected bladder to become more susceptible to injuries from impacts and the seat belt
Later stages of pregnancy where the gravid uterus displaces the bladder to the anterior Pregnant patients who adjust the lap belt for comfort can sustain further injuries
48
When a patient sustains a penetrating injury to the abdomen, it is important to
Attempt to determine the velocity of the object because it can predict the amount of damage to tissue
49
Low-velocity injuries
Caused by hand-held or hand powered objects such as knives Bleeding at the entrance wound may hide how far the the object went into the body, which is especially important to remember when an injury occurs in the region of the diaphragm
50
Medium velocity injuries penetrating wounds
Caused by smaller caliber handguns and shotguns; has temporary wound channels (caused by cavitation) in addition to the exit and entrance wounds
51
High velocity injuries
Caused by larger weapons such as rifles and higher-power handguns; has temporary wound channels (caused by cavitation) in addition to the exit and entrance wounds
52
Cavitation
When a cavity forms as the pressure wave from a projectile is transferred to the tissues causing microscopic tears to blood vessels and nerves, expanding the width and length of the wound Can produce significant bleeding Higher velocity = larger amount of cavitation and tissue damage
53
Any time there is an injury at or below the xiphoid process
Assume both thoracic and peritoneal cavities have been affected
54
Signs of abdominal injury
Early sign - tachycardia | Later signs - signs of shock, decreased BP, pale, cool and moist skin, and changes to the abdomen
55
Free air in the peritoneal cavity
Abnormal and typically indicates that a hollow organ or loop of the bowel has been perforated; very painful
56
The liver
The largest organ in the abdomen and very vascular; Can contribute to hypoperfusion of injured Pain is commonly referred to the shoulder
57
Pancreas and spleen
Bleed heavily when affected by blunt or penetrating trauma Spleen often injured in MVA, especially with improper seatbelt placement, steering wheel impact, bike crashes; Pain may refer to shoulder
58
If the diaphragm is penetrated
The bowel may herniate into the thoracic cavity and patients will exhibit dyspnea; may be worsened when patients are placed in a supine position
59
In pediatric patients in MVA or car v. bike accidents
The chest and abdomen are less protected and may experience significant transfer of energy The ribcage is flexible and can lead to extreme compression in the chest and abdomen but very few outward signs of injury
60
Falls in geriatric patients may lead to
Risk of injury to the aorta, liver, spleen because the abdominal organs have lost some elasticity
61
Rectal bleeding
May occur after sexual assault, colitis, ulcers, etc. Significant rectal bleeding can occur after hemorrhoid surgery and can lead to significant blood loss and shock
62
``` The first signs of peritonitis include all of the following EXCEPT: Severe abdominal pain Tenderness Muscular spasms Nausea ```
Nausea
63
``` Late signs of abdominal injury include all of the following EXCEPT Distention Increased BP Change in mental status Pale, cool, moist skin ```
Increased BP
