A Full English Breakfast
This patient was supposed to have starved for eight hours for her morning-scheduled breast surgery.
During the procedure, we were treated to the most disgusting sight—she regurgitated what can only be described as a partially digested English breakfast, with identifiable sausages, egg, beans, and possibly black pudding, up into her unprotected airway as she attempted to inhale the lot.
We managed to prevent the majority of it from going down, but she needed care for a day or so for her lungs to recover from the stomach acid. VolatileAgent81
