I thought we had difficult anesthetists, but "nothing compares to you".
No, we have not such a policy and even if we had, it would maximally be
4 hours. Specifically for the appendicitis situation, we don't use CT.
Can you direct me to some scientific evidence about sensitivity and
specificity of that method?
