Using a standardized model of uncontrolled hemorrhagic shock induced by massive splenic injury (MSI), we compared bolus infusion of Ringer's lactate (RL) and hypertonic saline (HTS), combined with splenectomy, to continuous infusion of these solutions and splenectomy in rats. ⋯ Continuous infusion of RL combined with splenectomy was followed by significantly less bleeding than bolus infusion of RL and improved survival time compared with untreated animals. Continuous HTS infusion and bolus infusion of HTS with splenectomy resulted in minimal blood loss and improved survival compared with untreated animals. No significant difference in blood loss or survival time was observed between bolus and continuous HTS infusion.

The purpose of this study was to determine the incidence of acute lung injury (ALI) in trauma patients with severe traumatic brain injury (TBI), to evaluate the impact of ALI on mortality and neurologic outcome after severe traumatic brain injury (TBI), and to identify whether the development of ALI correlates with the severity of TBI. ⋯ The development of ALI is a critical independent factor affecting mortality in patients suffering traumatic brain injury and is associated with a worse long-term neurologic outcome in survivors. The risk of developing ALI is not associated with specific anatomic lesions diagnosed by cranial CT scanning.

Many management schemes have incorporated mandatory head computed tomography (HCT) to evaluate a patient sustaining blunt head trauma with a history of loss of consciousness (LOC). Commonly, this is despite physical examination findings warranting such a workup. This study is intended to better identify the significance of selective criteria, a set of constitutional signs and symptoms (CSS) for head injury, to screen patients sustaining blunt head trauma and LOC. ⋯ The liberal use of HCT in patients without CSS for head injury did not influence patient care, with no increase in morbidity or mortality. These results suggest that LOC alone is not predictive of significant head injury and is not an absolute indications for HCT. More objective criteria, such as CSS, should be used before initiating a costly workup where further diagnostic and therapeutic intervention is unlikely after mild head injury.

The presence of a surgeon at the initial assessment and care of the trauma patient has been the focal point of trauma center designation. However, for Level I verification, the American College of Surgeons Committee on Trauma currently does not require the presence of an attending trauma surgeon in the hospital (IH), provided senior surgical residents are immediately available. Likewise, the state of Missouri does not mandate an IH presence of the attending trauma surgeon but requires senior (postgraduate year 4 or 5) level surgical residents to immediately respond, with a 20-minute response time mandated for the attending surgeon if IH or out of the hospital (OH). Nevertheless, some claim that IH coverage by attending surgeons provides better care for seriously injured patients. ⋯ As long as initial assessment and care is provided by senior level IH surgical residents and as long as the attending surgeon responds in a defined period of time (if OH) to guide critical decision-making, the IH presence of an attending surgeon has not been shown in this retrospective study to improve care of the critically injured patient.
