Advice for runs of dry cards during MTT?

Hey,

I just started playing more MTTs lately, as I have mainly played (and play SNGs). I was able to cash in three out of the 4 tourneys that I played recently. However, I ran into some trouble during the second hour or so as the blinds increased. I went card dead for a period during each of these tourneys, as I'm sure is expected for most toruneys. The problem was that as the blinds increased, both aggressive chipleaders and desperate short stacks made it so that nearly every hand was raised. I was wondering if anyone has any good advice regarding how to maintain or even build your chip stack when the blinds are getting up there and every pot seems to be raised. What tactics do you all take? Is it simply a matter of being patient and riding the storm out? Any replies are welcome and appreciated.
