Trauma Flashcards
Most common spontaneous dislocation recurrence
Anterior shoulder
Spinal cord syndromes:
Anterior cord
Complete motor, pain and temperature loss below the lesion
Spinal cord syndromes:
Brown-Sequard
Ipsilateral loss of motor, position and vibration sense; contra lateral loss of pain and temperature perception
Spinal cord syndromes:
Central cord syndrome
Greater motor weakness in upper extremity than lower extremity with varying degrees of sensory loss
Spinal cord syndromes:
Autonomic days reflexes
Urinary retention, massive increase in sympathetic tone which can cause HTN, treated by insertion of foley
Death from crush injury due to?
Renal failure
Complications of crush injury
DIC, compartment syndrome, renal failure, hyperkalemia
Trauma and kinematics:
High velocity
Above 2000 FPS
Trauma and kinematics:
Medium velocity
1000-2000 FPS
Trauma and kinematics:
Low velocity
Under 1000 FPS
Chest/ABD trauma:
Chest tube location?
Fourth IC space, anterior-axillary
Chest/ABD trauma:
Needle thoracostomy?
Second ICS midclavicular or the fifth ICS anterior mid-axillary line
Chest/ABD trauma:
Suspect with fracture of first 3 ribs
Aortic disruption
Chest/ABD trauma:
Scaphoid abdomen indicates?
Diaphragmatic rupture
Bowel sounds in chest cavity?
Diaphragmatic rupture, most common in the left chest
Crunching sound heard over chest with auscultation, may be synchronized with heart beat?
Associated with tracheobronchial injury and is called Hamman’s sign
Preferred method for moving spinal injured patients
Scoop stretcher is preferred rather then performing a log roll
Blood loss in humerus fracture
750ml
Blood loss in femur fracture
1500ml
Burns:
Parkland formula
4 ml x kg x TBSA. 1/2 over 1st 8 hrs, rest over next 16 hours
Burns:
Consensus formula
2-4 ml x kg x TBSA. 1/2 over 1st 8 hrs, rest over next 16 hours
Volume for RBC administration
10 ml/kg
Volume for WBC
20ml/kg
Diving injuries:
ATM
1 ATM for every 33 feet descent
Add 1 if asking for total ATM versus water pressure
Most common dislocation
Hip
