Automated blood pressure (BP) determinations by oscillometry are reported to be as accurate as invasive monitoring for systolic pressures as low as 80 mm Hg. Automated BP devices are widely used by prehospital providers and in hospital operating rooms, emergency departments, and intensive care units, although the accuracy of automated BP has not been demonstrated in trauma patients. We hypothesized that automated BP is less accurate than manual BP in trauma patients. The purpose of this study was to determine the accuracy of automated BP versus manual BP in trauma patients. ⋯ Injury severity, degree of acidosis, and resuscitation volume were more accurately reflected by manual BP. Automated BP determinations were consistently higher than manual BP, particularly in hypotensive patients. Automated BP devices should not be used for field or hospital triage decisions. Manual BP determinations should be used until systolic blood pressure is consistently > or = 110 mm Hg.

Blunt injury to the colon is rare. Few studies of adequate size and design exist to allow clinically useful conclusions. The Eastern Association for the Surgery of Trauma Multi-institutional Hollow Viscus Injury (HVI) Study presents a unique opportunity to definitively study these injuries. ⋯ Colonic injury after blunt trauma is rare and difficult to diagnose. No diagnostic test or combination of findings reliably excluded blunt colonic injury. Despite the inadequacy of current diagnostic tests, almost all patients with colonic injury were taken to the operating room within 24 hours. Even with relatively prompt surgery, patients with colon injury were at significantly higher risk for serious complications and increased length of stay. In contrast to small bowel perforation, delay in operative intervention appears to be less common but is still associated with serious morbidity.

The purpose of this study is to compare techniques for the diagnosis of suspected ventilator-associated pneumonia in the trauma patient. Per the literature, bronchoscope protected brushings and bronchoalveolar lavage were set as the standards for comparison because of their high specificity and sensitivity. We hypothesized that blind protected brushings were equivalent to bronchoscope-directed techniques and that endotracheal aspirates (ETA) were not. ⋯ A quantitative analysis of bacteriologic cultures obtained by four standard sampling techniques has demonstrated with statistical significance that no difference exists between modality of sampling in reliability or in obtaining clinically significant pathogens. In reviewing the literature, this study is the first assessment of agreement for cultured pathogens between the four different sampling modalities and the largest to assess the efficacy of the blind protected brush technique.

Recombinant coagulation factor VIIa (FVIIa) is approved for treating hemophiliacs with inhibitors. High-dose FVIIa has also been used off-label to manage hemorrhage in trauma and surgical patients, many of whom also develop hypothermia and acidosis. ⋯ FVIIa should be effective in enhancing hemostasis in hypothermic patients. However, because the activity of FVIIa is so dramatically affected by pH, its efficacy may be reduced in acidotic patients.
