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.

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.

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 examine the occurrence of hypotensive episodes in patients with severe traumatic brain injuries that are not of hypovolemic origin and to investigate possible neurogenic or iatrogenic causes of such episodes. ⋯ (1) Some episodes of severe traumatic brain injury-related hypotension may be of neurogenic origin. (2) The risk/benefit ratio of early diuretic use in patients with severe traumatic brain injuries may be too high to support liberal use. These data strongly support the need for a study involving prospective collection of data describing the early blood pressure courses in such patients.
