How to calculate a confidence interval from a single value?

How does one calculate a confidence interval of a single measurement?
Without a standard deviation (not reliable from a single measurement), it
does not seem possible to calculate a confidence interval.

Now I know what the standard deviation of this measurement is from a
history of this measurement (same method, instruments, operators, etc.).
Can I use the historical standard deviation as the standard deviation of
the current singlicate measurement to estimate the confidence interval of
the current measurement?
