Do You Need to Do a Colon Culture?

If the patient had perforated bowel, this is the first time they're hoping, would you want them to culture like a wash out fluid? In many of these situations, you really don't need to perform a culture because again, you know what's going to be there. A lot of times in these intra-abdominal infections, you start the patient on something and you know, that's probably what they're going to get for three or four or five days.
