The purpose of this study was to determine the effect of inhaled nitric oxide (NO) on oxygenation, hemodynamics, and ventilation in patients with adult respiratory distress syndrome (ARDS). ⋯ Inhaled NO improves oxygenation and pulmonary hemodynamics in patients with ARDS. However, the improvement to NO is variable.

The presentation, diagnosis, and successful management of posttraumatic pseudoaneurysms of the intraparenchymal splenic artery after nonoperative therapy in an adult patient is described. Pseudoaneurysm formation of the intraparenchymal splenic artery is a rare complication of traumatic splenic injury, which is a potential mechanism of delayed splenic rupture and demonstrates the importance of follow-up in the nonoperative therapy of blunt injury to the spleen.

Nonoperative management of blunt splenic trauma is widely accepted; however, reported failure rates have ranged as high as 40%. There are few factors available to identify failures reliably. To characterize failures of nonoperative management better, we retrospectively reviewed 309 blunt splenic injuries treated at our level I trauma center over a 5-year period. ⋯ Upon review of the initial computed tomography scans, a hyperdense collection of contrast media in the splenic parenchyma, or "contrast blush," was noted in 8 of 12 (67%) patients who failed and in 5 of 77 (6%) of those who were successfully managed nonoperatively (p < 0.0001). These data suggest that the presence of a contrast blush is an important consideration when deciding the method for management of the splenic injury. If these results are confirmed in a prospective fashion, the failure rate of nonoperative management of blunt splenic trauma could be reduced by identification of the contrast blush.

The purpose of this study was to evaluate the sensitivity, specificity, and predictive value of diagnostic laparoscopy (DL) in a large group of stable patients with abdominal gunshot wounds (ABGSWs). ⋯ In stable patients with ABGSWs and questionable intra-abdominal injury, DL can be safely used. It is highly sensitive and specific. It can effectively reduce the incidence of negative and nontherapeutic laparotomies, and the overall morbidity and hospital stay in this group of patients.

This is a retrospective study of 173 patients with gunshot injuries of the major arteries of the extremities. A selective policy for the use of angiography was followed. The arterial repair was achieved by various means: primary end-to-end anastomosis, vein interposition graft, and polytetrafluoroethylene (Teflon) interposition grafts. ⋯ There were 3 preoperative deaths, 1 intraoperative death, and 5 postoperative deaths (overall perioperative mortality, 3.5%). We conclude that the results of vascular extremity gunshot injuries are satisfactory when standard methods of management are used. Morbidity and mortality can be further reduced by prompt admission to appropriate centers.
