protocol
while i cannot say for sure without asking some one hiding in some office, i can safely say that i think that there is no protocol in this regard. i have worked in four hospitals in the uk and more in my country sri lanka. in this time i must have easily worked with atleast a hundred different anesthetists , senior and junior. yet never have i encountered anyone mention a protocol . we do have protocols for emergency situations such as cardiac arests and failled getting a pateint to breath etc , but never seen one with this regard.
