I take off my armor and use it to wedge the door so it can't be fully opened. Then I start banging my helmet against the wall until the guards can't stand it any more and come in to make me stop. Because I wedged the door they have to come in one at a time, and I stun the first one as he comes in. Then I can grab his sword and fight the other one. Since he's in chainmail and I'm not, I'm lighter and I just need to run past him towards the exit. I'm not too worried about hurting them a little, because they can't be that chivalrous if they were planning to torture me.
