Trauma Flashcards
Signs and symptoms of shoulder dislocation
- Severe pain
- Flattened shoulder
- Guarding of affected limb by holding it towards the torso
- Numbness of the hand due to nerve damage
- Impaired range of motion
How much blood can a patient lose from a
- Individual rib fracture
- Tibial fracture
- Femur fracture
- Pelvic fracture
- 100-200 mL
- 300-500 mL of blood
- 800 - 1000 mL
- 2000 mL
If the fractures are open, the figures are doubled
What are the signs and symptoms of head and spinal injuries
altered level of consciousness, seizures, nausea, vomiting, decreased movement and numbness of extremities, unequal pupils, blood ore cerebrospinal fluid leaking from ears
What is Paraparesis
a partial paralysis or weakness in both lower extremities that can affect motor or sensory function.
Superficial (first-degree) burn
Involves only epidermis
Patient presents with erythema and pain at site without blistering
Describe the two types of second degree burns: superficial partial-thickness and deep partial thickness burns (second degree burns)
Superficial partial thickness: Involves epidermis and dermis resulting in thin-walled, fluid filled burns that appear pink, moist, soft and tender
Deep partial-thickness burns: Extend into reticular dermis, skin color is mixture of red and blanched white, capillary refill is slow
Full thickness burns
Burns are dry, dark brown, charred, and feel hard to the touch
If nerve endings are destroyed, sensation may be lacking
What is the Rule of 9s for children
18% for the head
18% for the chest
18% for the back
9% for each arm
13.5% for each leg
1% for genitalia
What are the characteristics of severe pediatric burn injuries
- partial-thickness burn > 10%
- any full-thickness burn
- circumferential burns
- electrical, chemical, or inhalation injury
- burns of critical areas such as face, hands ,feet or joints
What is the Rule of Nines for adults?
For an adult, the entire head is equal to 9% of the body’s surface area.
The front and back of each arm and hand equal 9% of the body’s surface area.
The anterior torso is equal to 18% (chest equals 9% and the abdomen equals 9%) of the body’s surface area.
The posterior torso is equal to 18% of the body surface area.
The front and back of each leg equal 18% of the body’s surface area.
The genitalia equal 1% of the body’s surface area.
Why are pelvic fractures life-threatening and how would you manage it.
Life-threatening due to a significant amount of blood loss
It can be managed by
- Stabilizing the pelvis with a pelvic binder (if protocols allow) or
- Tying a sheet around the pelvis
- Securing a long device such as a scoop stretcher or long spine board to prevent further injury during transport
- treating for shock,
- rapidly transporting to a trauma center
What patients do not require spinal motion restriction
- a normal level of consciousness (Glasgow Coma Score 15)
- no spine tenderness or anatomic abnormality
- no neurologic findings or complaints
- no distracting injury
- no intoxication
Crush syndrome
Can develop when an area of the body is trapped for longer than four hours and arterial blood flow is compromised
Primary blast injuries
Occur due to the pressure wave caused by the explosion. Common injuries are ruptured tympanic membrane, lung injury, and injury to hollow organs
Secondary blast injuries
result from being struck by the flying debris scattered from the explosion as projectiles.
Tertiary blast injuries
result from the patient’s body being displaced against stationary objects, such as trees, buildings, or the ground
