Abstract
BACKGROUND: The introduction of broad spectrum antibiotics has substantially decreased rates of mortality and morbidity associated with complicated appendicitis in children. The generally recommended therapy for children with complicated (gangrenous or perforated) appendicitis is administration of postoperative antibiotics for 3 to 14 days, but the decision as to the specific duration of treatment lies with the treating physician. AIM: This study evaluates whether the recommendation that the combination of the patient's being afebrile and eating and having a normal white blood cell (WBC) count and < or = 3% band forms can be used to decide when sufficient antibiotics have been given and can be safely discontinued. METHODS: Thirty-three consecutive patients seen in the pediatric surgical service with perforated or gangrenous appendicitis were studied prospectively. All patients received a standard protocol of resuscitation, appendectomy and broad spectrum antimicrobial therapy to be continued until they were eating, afebrile and had normal white blood cell counts with < or = 3% immature neutrophils (band forms). RESULTS: Thirty-two children were treated until they met all criteria when antibiotics were stopped and the patients were discharged. Of these patients 31 had unremarkable courses of recovery with no development of intraabdominal abscess or wound infection [predictive value of criteria, 97% (31 of 32)]. The remaining patient who met the criteria required rehospitalization for treatment of intraabdominal abscess. Another patient was discharged prematurely when he failed to meet the criterion of afebrility. Although he was eating and his WBC count was normal, he had a temperature of 38.5 degrees C during the 24 h before discharge. He was readmitted for surgical drainage of an intraabdominal abscess, yielding a 100% predictive value for the criterion mismatch (1 of 1). CONCLUSION: Based on our observations, when a patient with complicated appendicitis is afebrile for 24 h (temperature < 38 degrees C), is eating and has a WBC count with < or = 3% band forms, antibiotics can be safely discontinued with small risk of recurrent intraabdominal abscess.
