People Also Ask
What does ED 50 / SFU 50 mean?
It's a coded, tongue-in-cheek request to anaesthesia staff to sedate a patient who has become disruptive, punning on the pharmacology term ED50 ('effective dose 50').
Where does the term come from?
It plays on 'ED50,' the median effective dose in pharmacology, crossed with 'SFU' (a euphemism for 'shut up').
Is it a real medical order?
No. It's dark hospital slang used informally among staff, not an actual clinical prescription.
