Echoing what ninane said about prologue/epilogue and POV, I'll just add the following.
Are you trying for a feeling of immediacy? Tension? Maybe changing the rhythm of the prose, using hard sounding words and short sentences might help. What effect are you trying to set up in the scene? What do you want the reader to come away with after reading it?
Also, I've sometimes found that switching to a different character's POV sometimes helps a scene to gel better.
Hope this helps.
