What is anaphylaxis
You answer Mr Brown’s buzzer and when you enter his room he is obviously distressed and is thrashing around on his bed. He complains of difficulty breathing and has an audible stridor (high pitched wheezing sound). You know that he commenced his first dose of intravenous penicillin 10 minutes ago via an infusion pump. You suspect that Mr Brown is having an anaphylactic reaction.
