To determine whether physical examination alone or in combination with biochemical markers can accurately diagnose hypoperfusion. ⋯ Combining physical examination with serum bicarbonate and arterial lactate identifies patients with hypoperfusion as defined by low Svo2 and cardiac index. Hypoperfusion may occur despite supranormal cardiac indices. Patients with cool extremities and elevated lactate levels may benefit from a pulmonary artery catheter to guide but not initiate therapy.

The effect of age and infection on outcome after trauma is unknown. We evaluated the incidence and impact that nosocomial infection (NI) and age have on morbidity and mortality. Several risk factors were identified and analyzed for correlation with infection. ⋯ NI significantly increases hospital LOS, ICU LOS, and mortality after injury. Age increases risk of infection matched for injury severity, with a significantly higher hospital LOS, ICU LOS, and mortality. Once infected, however, younger patients with penetrating trauma have the greatest risk of mortality. Chronic obstructive pulmonary disease in elderly trauma patients was found to be an independent predictor of infection.

The purpose of this study was to determine the safety of early weight-bearing after statically locked reamed nailing of comminuted fractures of the femoral diaphysis, and to assess the rate of implant failure and fracture healing. ⋯ This study showed that early weight-bearing after reamed static interlocking nailing of Winquist type II, III, and IV femoral fractures is a safe and effective method, and the risk of implant failure does not preclude the procedure.

Prone positioning and inhaled nitric oxide: synergistic therapies for acute respiratory distress syndrome.
Inhaled nitric oxide (INO) and prone positioning have both been advocated as methods to improve oxygenation in patients with acute respiratory distress syndrome (ARDS). This study was designed to evaluate the relative contributions of INO and prone positioning alone and in combination on gas exchange in trauma patients with ARDS. ⋯ INO and prone positioning can contribute to improved oxygenation in patients with ARDS. The two therapies in combination are synergistic and may be important adjuncts to mechanical ventilation in the ARDS patient with refractory hypoxemia.

Traumatic brain injury poses a serious public health challenge. Treatment paradigms have dramatically shifted with the introduction of the American Association of Neurologic Surgeons (AANS) Guidelines for the Management of Severe Head Injury. Implementation of the AANS guidelines positively affects patient outcomes and can be successfully introduced in a community hospital setting. ⋯ Implementation of a traumatic brain injury protocol in a community hospital setting is practical and efficacious. Appropriate invasive monitoring of systemic and cerebral parameters guides care decisions. The protocol results in an increase in resource usage, but it also results in statistically improved outcomes justifying the increase in expenditures.
