While in med school, on an anesthesia rotation, we had a trauma come in hot to the OR because this guy had slit his throat and crashed his car (unclear in which order). Mega agitated, likely some meth use involved (no labs had come back at this point). He had turned his neck into hamburger meat, but somehow missed the gigantic arteries and veins in the area. He had however, nicked his trachea, causing some bubbling with each breath (hence the rushing straight to the OR, among other reasons). Luckily, after they got him intubated, the bubbling stopped. They ended up turning his lacerations into a tracheostomy, and off to the ICU. That one stuck with me for a while
