Young man was brought to the ED w/ sudden pain in right eye after cutting weeds w/ power trimmer. Opening eye or moving it makes pain worse. Thoughts?
The nail is embedded in the center of the right globe, & there is bleeding. Vital signs & remainder of exam, including peripheral neuro exam, were normal.
The nail traversed the right orbit, narrowly missed the globe, and penetrated the ethmoid and sphenoid bones; its tip rested against the clinoid portion of the contralateral internal carotid artery.
70-year-old man was stabbed in the left neck by three tines and he was fully conscious and w/o neurological deficits. Paramedics cut down the tines. What structures are you worried about?
Imaging showed a tine penetrated transverse foramen, obstructed left vertebral artery V2 segment, & oozing from VA beside the metal tine. His epiglottis was swollen but there was no air leak. Plan?
So how to manage airway, oozing and obstructed vertebral artery, risk of stroke, and risk of bleeding out? What do you do first?
Warning Sensitive Clinical Image: Total Scalp Avulsion. Young patient was working in a factory when machinery caught her hair removing her entire scalp. Fortunatey, w/ urgent reconstitution of superficial temporal vessels flow the scalp was salvagable & she had a great outcome.
Miracle Outcome: Two-year-old boy was enjoying his meal, fell down, and a single chopstick penetrated though his mouth and went intracranially passing right by his brainstem. 🧵
On admit, his vital signs were stable and he was breathing well. Neurologically, eyes opened to pain, he was confused, and he did localize symmetrically. Thoughts on management? (not my case, reference to follow).
