What Would You Do?
You are called to the grandstands near the "start/finish" line. A 60-year-old spectator was not wearing ear protection during the "loudest lap" of the race. He suddenly felt a sharp pain in his ear and noticed "liquid" draining from it.
Patient Presentation: The patient is dizzy (vertigo) and says his hearing is "muffled" in the left ear. You see a small amount of clear/bloody fluid draining from the ear canal.
1. A sudden, loud noise that causes pain and fluid drainage from the ear often indicates:
A. A common ear infection.
B. A ruptured tympanic membrane (eardrum).
C. A migraine.
D. Cauliflower ear.
2. How should an EMR manage fluid draining from the ear after a loud noise or trauma?
A. Plug the ear tightly with a cotton swab or finger.
B. Cover the ear loosely with a sterile dressing to catch the fluid, but do not apply pressure or block the flow.
C. Pour hydrogen peroxide into the ear to clean it.
D. Tell the patient to "pop" his ears by blowing his nose.
3. Why should you avoid plugging the ear or stopping the flow of fluid?
A. Because it is uncomfortable for the patient.
B. Because stopping the flow can increase pressure inside the ear or head, and the fluid might be Cerebrospinal Fluid (CSF) if there is an underlying skull fracture.
C. Because the fluid needs to evaporate.
D. Because it makes the dressing too wet.
Answers:
1. B. The acoustic energy of a stock car engine can reach 140+ decibels, which is enough to physically tear the tympanic membrane.
2. B. Never block the flow. If the fluid is CSF (indicating a "Basilar Skull Fracture"), blocking it can lead to a dangerous buildup of pressure or infection in the brain.
3. B. If the drainage is clear and "halo-like" on a dressing, it suggests a skull fracture. Loosely covering it protects the area without creating dangerous back-pressure.
