Comparative Study
Computed tomography in the management of blunt thoracic trauma.
Computed tomographic (CT) scanning has proved to be valuable in evaluating the head and abdomen of victims of blunt trauma; CT scans of the thorax often are obtained on patients with blunt torso trauma, but their value for this purpose is unclear. We conducted a prospective study to evaluate the role of chest CT scanning in thoracic trauma. Hemodynamically stable patients at least 18 years old with an estimated Abbreviated Injury Scale--Thorax score of 2 or greater underwent a contrast-enhanced CT scan of the chest, usually in conjunction with CT scans of the head, abdomen, or both. ⋯ Four patients died (6%), three from head injury and one from multiple organ dysfunction. Chest roentgenography (CXR) was superior to CT scanning in identifying rib fractures, but CT scanning was more sensitive than CXR for pneumothorax, fluid collections, and infiltrates (p < 0.001); CT scanning also was more specific for aortic injury. Despite this quantitative superiority, the abnormalities missed by CXR but identified by CT scanning infrequently led to a change in management.(ABSTRACT TRUNCATED AT 250 WORDS)

Two different hypertonic (2400 mOsm/L) isochloremic dextran solutions (sodium acetate, HAD; and sodium lactate, HLD; in 0.9% NaCl + 6% dextran 70) were compared with HSD (2400 mOsm/L NaCl + 6% dextran 70) as initial treatment for severe uninterrupted arterial bleeding. The substitution of dextran 70 for lactated Ringer's solution as the maintenance isotonic infusion fluid was also analyzed. ⋯ A recently developed model, pressure-driven hemorrhage (PDH), which mimics uninterrupted arterial bleeding, was employed. It was found that (1) the substitution of dextran 70 for lactated Ringer's as isotonic fluid makes no difference in hemodynamic terms; (2) isochloremic hypertonic solutions are similar in their hemodynamic resuscitative effect, representing an improvement over hypertonic NaCl in terms of cardiac output, O2 delivery and O2 consumption; (3) HAD proved superior to HLD in terms of O2 consumption and correction of pH/base excess.

From 1980 through 1990 14 patients with severely complicated unstable fractures of the pelvis were treated. There were 13 men and one women (mean age, 28 years). Eight fractures also involved the acetabulum. ⋯ At last follow-up examination all patients were continent for feces. It is concluded that early internal stabilization of these complex injuries achieves a low mortality rate and good functional results. Immediate repair of urogenital and sphincter lesions, with concomitant divergent stoma and lavage of the distal colon, gives good results notwithstanding the risk of infectious complications.

Case Reports
Endoscopic retrograde cholangiography in the nonsurgical management of blunt liver injury.
Injury to the intrahepatic bile duct has not been routinely examined in patients with blunt liver injury, despite the risk of formation of a biloma and hemobilia. In this study we examined the role of endoscopic retrograde cholangiography (ERC) in the evaluation of blunt liver injuries. ⋯ Patients with hepatic parenchymal injuries that were observed on the CT scans were at greatest risk for injury to the intrahepatic bile duct, and our data suggested that the incidence of injury to the intrahepatic bile duct after blunt hepatic trauma is higher than previously reported. Patients with serious hepatic parenchymal injuries who are candidates for nonsurgical management should be considered for ERC to exclude the possibility of injury to the bile duct.
