I'd like to ask you some questions:
1.- What kind of peritonitis? For example, do you use it in an appendicular peritonitis?
2.- When? Primarily? or in second or third looks?
3.-Is there any difference with the sole use of saline solution?
I may say that the use of the antibiotic irrigation is going to act in the consecuence place not in the cause. It may produce loosing time, for meanwhile one might expect good results, NOT treating the fountain.
