This CODE BROWN word was devised by one of my group members when we were doing our emergency rotation. I don't really remember the exact circumstances but I think we were somehow trying to get to this cubicle where we thought there was something exciting going on. But even before we managed to step in, we were hit right in the face with this most offensive odour. That's when the guy in front immediately turned around and announced: "Code Brown!" And in no time the ED was more spacious with the disappearance of 5 guys. And the other thing - we were told when we were doing our nephrology rotation that sometimes drug addicts would present to the ED with "renal colic" which in genuine cases results in the worst pain ever hence requiring the administration of a potent analgesia such as morphine.
