Murray,

There are a host of articles on how to prolong vase life,
particularly in carnations.  Most of these are in the
horitculture journals.  Fundamentally, blocking ethylene
production and/or ethylene responses is one aspect,
controlling the proliferation of microorganisms is a second,
maintaining decent transpiration flow is a third, and
providing substrate (sucrose etc) is a fourth.  There
may be others, but these top the list in my opinion.
There are good articles on each of these almost every
year.
