PHTLS - Prehospital Trauma Life Support Spinal Trauma Management Questions and Answers

Question 1

A 22-year-old male is involved in a high-speed motorcycle collision. He is found wearing a full-face helmet. He is unconscious, breathing spontaneously, and has a strong radial pulse. According to PHTLS principles, what is the most appropriate action regarding the helmet?

Accepted Answer

Remove the helmet only if it interferes with airway management or breathing.

Answer

PHTLS guidelines recommend helmet removal when it prevents a thorough assessment or management of the airway and breathing. Since the patient is unconscious, the airway is at risk and cannot be fully assessed with the helmet on. Removal should be performed by two trained rescuers to maintain manual spinal stabilization.

Question 2

You are assessing a patient who fell 15 feet from a ladder. The patient is hypotensive with a blood pressure of 80/50 mmHg, has a heart rate of 58 bpm, and their skin is warm and dry. Which of the following conditions is MOST likely responsible for this presentation?

Accepted Answer

Neurogenic shock from a spinal cord injury.

Answer

The classic presentation of neurogenic shock is hypotension combined with bradycardia (or a normal heart rate) and warm, dry skin. This occurs due to the loss of sympathetic tone below the level of a high spinal cord injury (typically above T6), leading to vasodilation and an unopposed parasympathetic response on the heart. Hypovolemic shock would typically present with tachycardia and cool, clammy skin.

Question 3

Which of the following findings in a conscious adult patient with blunt trauma is an absolute indication for initiating spinal motion restriction (SMR)?

Accepted Answer

The presence of a painful and distracting long bone fracture.

Answer

A distracting injury is a condition thought to be producing pain significant enough to distract the patient from a second (e.g., spinal) injury. PHTLS guidelines, based on consensus statements, indicate that a distracting injury makes the spinal assessment unreliable, thus mandating the application of spinal motion restriction. While a significant MOI and intoxication are risk factors that increase suspicion, a distracting injury is a specific criterion that necessitates SMR in an otherwise assessable patient. SMR is generally not indicated for penetrating trauma without neurologic deficit.

Question 4

A 68-year-old female experiences a syncopal episode and falls down two stairs. She is now alert, oriented, and denies any neck pain. She has no palpable tenderness along her spine, no focal neurologic deficits, and no evidence of intoxication. However, she has a large, painful hematoma on her forehead. What is the most appropriate spinal management for this patient?

Accepted Answer

Apply a cervical collar and secure her to the ambulance cot.

Answer

This patient meets criteria for spinal motion restriction (SMR) due to a distracting injury (painful forehead hematoma) and age (>65), which make her clinical exam unreliable for ruling out a spine injury. Current PHTLS principles emphasize spinal motion restriction, which involves applying a cervical collar and securing the patient to the ambulance cot, rather than routine use of a long backboard for transport. The long backboard is primarily an extrication device.

Question 5

A patient involved in a rear-end motor vehicle collision is complaining of neck pain. Your assessment reveals marked weakness and numbness in both arms and hands, but he is able to move his legs and wiggle his toes with good strength. This pattern of neurologic deficit is most characteristic of which spinal cord injury syndrome?

Accepted Answer

Central Cord Syndrome

Answer

Central Cord Syndrome is the most common incomplete spinal cord injury and is often caused by a hyperextension injury. It characteristically results in motor weakness that is more pronounced in the upper extremities compared to the lower extremities, with variable sensory loss.
