Peritoneal fluid on abdominal computed tomographic (CT) scan in the absence of solid-organ injury suggests a bowel injury. We sought to determine the significance of peritoneal fluid as the sole finding on abdominal CT scans obtained to evaluate injured pediatric patients. ⋯ Intra-abdominal fluid as the sole finding on abdominal CT scan does not mandate immediate celiotomy in the bluntly injured pediatric patient. The patient with fluid in more than one location has a 50% chance of bowel injury. We also conclude that extravasated enteral contrast is rarely present to aid in the diagnosis of bowel injury in children.

To analyze the parameters measured in the field, during transport, and upon arrival of the physiologic condition of patients sustaining penetrating cardiac injuries, along with the Cardiovascular Respiratory Score (CVRS) component of the Trauma Score, the mechanism and anatomical site of injury, operative characteristics, and cardiac rhythm as predictors of outcome. We also set out to identify a set of patient characteristics that best predict mortality outcome and to correlate cardiac injury grade as determined by the American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS) with mortality. ⋯ Parameters measuring physiologic condition, CVRS, and mechanism of injury are significant predictors of outcome in penetrating cardiac injuries. AAST-OIS injury grades I-III are rare in penetrating cardiac trauma. AAST-OIS Injury grades IV-VI are common in penetrating cardiac trauma and accurately predict outcome.

By using abdominal computed tomographic scans in the evaluation of blunt splenic trauma, we previously identified the presence of vascular blush as a predictor of failure, with a failure of nonoperative management of 13% in that series. This finding led to an alteration in our management scheme, which now includes the aggressive identification and embolization of splenic artery pseudoaneurysms. ⋯ Aggressive surveillance for and embolization of posttraumatic splenic artery pseudoaneurysms improved the rate of successful nonoperative management of blunt splenic trauma to 61%, with a nonoperative failure rate of only 6%. In comparison with our previous work, this reduction in failure of nonoperative management is a significant improvement (p < 0.03).

Increased intestinal permeability (IP) and the release of toxic intraluminal materials have been implicated in the systemic inflammatory response syndrome (SIRS) and multiple organ failure (MOF) observed in patients after severe trauma. Previous studies of intestinal permeability have failed to demonstrate a correlation between early measurements of IP and indicators of injury severity. This study examines the relationship between standard measures of injury severity and the early (day 1) and delayed (day 4) changes in IP. Associations between IP and the development of SIRS, MOF, and infectious complications were also studied. ⋯ These observations demonstrate that the increased IP observed after trauma correlates with severity of injury only after 72 to 96 hours and not within the initial 24 hours of injury. A large increase in IP is associated with the development of SIRS, multiple organ dysfunction, and an increased incidence of infectious complications.

To define the incidence, prophylaxis, and treatment of intra-abdominal hypertension (IAH) and its relevance to gut mucosal pH (pHi), multiorgan dysfunction syndrome, and the abdominal compartment syndrome (ACS). ⋯ IAH is frequent after major abdominal trauma. It may cause gut mucosal acidosis at lower bladder pressures, long before the onset of clinical ACS. Uncorrected, it may lead to splanchnic hypoperfusion, ACS, distant organ failure, and death. Prophylactic mesh closure of the abdomen may facilitate the prevention and bedside treatment of IAH and reduce these complications.
