AbstractClinical data and computed tomographic (CT) scans for 1,486 children evaluated after blunt abdominal trauma were reviewed to determine whether peritoneal fluid is a reliable indicator of the presence and severity of associated intraabdominal injury and the need for laparotomy. The CT scans were assessed for presence, location, and severity of intraabdominal injury, and amount of peritoneal fluid. Type of management (surgical or nonsurgical), indications for surgical management, overall hospital course, and clinical outcome were recorded at the time of discharge. Of the 326 children with abdominal injuries detected by CT, 121 (37%) had no associated peritoneal fluid collections. Eighteen (15%) of these children had injury to more than one abdominal organ. Splenic injuries by CT criteria were more severe in children with associated peritoneal fluid than in those with no associated fluid (P < .003). There were no significant differences in CT grading of liver and renal injuries among those with and without associated peritoneal fluid (P > .67). Two hundred fifty-nine (17%) of the 1,486 children had peritoneal fluid demonstrated by CT. Eighty percent of these children had concomitant intraabdominal injury. Associated injuries included solid organ injuries (in 68% of patients) hollow viscus or mesenteric injury (11%), isolated pelvic fracture (4%), and hypoperfusion syndrome (5%). Thirty-one patients (12%) had injury to more than one abdominal organ. Only 27 (11%) patients had small "unexplained" collections of peritoneal fluid in which no associated injury was detected through CT or clinical follow-up. The authors conclude that (1) solid organ injury is frequently present in the absence of peritoneal fluid, and (2) the identification of peritoneal fluid after blunt trauma should lead one to suspect that a specific intraabdominal injury is the cause of the fluid.
