Comparative Study
Immunologic function in the elderly after injury--the neutrophil and innate immunity.
Aging is associated with a decline in immune function. This may contribute to decreased ability of an elderly patient to mount an appropriate innate inflammatory response when injured. This study examined elderly trauma patients to determine whether there was a difference in neutrophil response to injury when compared with controls. ⋯ Injury results in differences in innate immune function in the elderly when compared with controls. The clinical significance of this is uncertain and warrants further investigation.

Femoral shaft fractures are associated with acute respiratory distress syndrome (ARDS). The idea that primary intramedullary nailing increases the incidence of ARDS has theoretical support. Our approach to treating femoral fractures in patients with multiple traumatic injuries is to perform reamed nailing after adequate resuscitation has been shown by normalizing lactate plus optimized ventilatory and hemodynamic parameters. Damage control orthopedics (DCO) with primary external fixation usually is reserved for those rare patients who do not respond to resuscitation. Our hypothesis was that this approach yields a low rate of ARDS. ⋯ In the context of resuscitation before reamed intramedullary nailing of femoral shaft fractures, our rate of ARDS was lower (p < 0.001) than that of a similar study reported in the literature in which the DCO approach was used in up to 36% of patients (p < 0.001) and was more in keeping with previously reported rates of ARDS. This remained true despite frequent use of early reamed femoral nailing and infrequent use of DCO. An explanation for the discrepancy between the centers might be differences in preoperative resuscitation or medical care provided to treat shock.

Hyperglycemia is associated with increased mortality in the severely injured; intensive insulin protocols reduce mortality, improve wound healing, and decrease susceptibility to infection. High glucose variability creates challenges to glycemic control and may be a marker of poor outcome. We wondered whether glycemic variability alone might identify patients at higher risk of death. ⋯ High glucose variability (>50% of values outside 80-110 mg/dL) is associated with increased mortality in the severely burned. Individuals with frequent excursions outside the glucose target range of 80 mg/dL to 110 mg/dL are at greater risk of death.

Injuries sustained while skiing or snowboarding are commonly encountered in emergency departments near winter resorts. The purpose of this study is to identify and compare the types of injuries likely to be found in the skier or snowboarder patient. An additional goal of this study is to provide a description of the demographics and hospitalizations for these patients. ⋯ Patients injured while skiing or snowboarding are predominantly men, and participants in both sports are at risk for sustaining major injuries. The types of injuries differ and are dependent on the sport. An awareness of these differences will help skiers and snowboarders minimize their risk of injury by altering their riding strategies and by choosing appropriate protective equipment.

In trauma patients, elevated body temperature is a common and noninfective procedure soon after injury. We hypothesized that the absence of this febrile response is associated with failure to meet metabolic demands and results in adverse outcomes. ⋯ A febrile response until day 4 after injury did not increase morbidity, and a low AUC is independently associated with adverse outcomes. These findings show that a nonfebrile response soon after injury results in poor prognosis.
