The next morning the patient was unable to pass his water, and had to be catheterized. Aside from this no ill effects were seen, and his temperature and pulse remained practically at the same place. At the end of 48 hours the drains and dressings were changed and the patient was doing well and the wound draining profusely. At no time was the bed elevated and at no time was a stimulant administered, with the exception of a hot normal salt enema on the day following the operation. Several times during his stay a dose of castor oil was given, but no other medication was necessary. As the dressings were reapplied and drains introduced daily the wounds were found to be granulating up, and gradually these closed, first the one in the lumbar region and then the one in the abdomen. By the tenth day a normal temperature was present, and he sat up on the twelfth. The child went on to an uneventful recovery, and went home on January 21st fully cured. This was undoubtedly one of those cases of gangrenous appendicitis where, owing either to the intensity of the infection or to a thrombosis of the vessels supplying the appendix, the vitality of the tissues is lost and gangrene results. Now, "even in this, the gravest form of appendicitis, the general peritoneal cavity is often protected against infection by walling off the pus, and the appendix, detached in the form of a slough, is often found on opening the localized abscess." But "in other cases there is from the beginning the symptoms of peritoneal sepsis and peritonitis." Now, it seems to me that a great deal depends on the kind of infection--or, rather, the kind of organism infecting--and often the difference between a localized abscess and a general peritonitis is really the difference between a colon and a streptococcus infection. Again, should a general peritonitis develop, I have noticed from a number of cases in the wards that the prognosis practically depends on the organism, although we all know that a general peritonitis is a mighty grave condition, no matter what it is due to. Another point in favor of the child was the fact that the gangrenous process seemed to start in the tip of the appendix, and it seems that when it starts there, there is greater likelihood of localization, and when it starts in the base a greater likelihood of general peritonitis.
