Pulseless electrical activity (PEA) secondary to both blunt and penetrating trauma is associated with minimal survival. The pericardial view of the focused abdominal sonography for trauma (p-FAST) can differentiate between patients with and without organized cardiac activity and may assist in the decision to terminate ongoing resuscitation. ⋯ The presence of PEA at any time during initial resuscitation is a grave prognostic indicator. p-FAST is a useful test to identify contractile cardiac activity. p-FAST may identify those patients with potential for survival.

Acute respiratory distress syndrome (ARDS) has been shown to increase morbidity but not mortality in trauma patients; however, little is known about the effects of ARDS in nontrauma surgical patients. The purpose of this study is to evaluate the risk factors for and outcomes of ARDS in nontrauma surgical patients. ⋯ Unlike trauma patients, ARDS was an independent predictor of ICU mortality in nontrauma surgical patients, independent of age and disease severity. Nontrauma surgical patients who developed ARDS were older, sicker, and had a longer ICU stay. Independent predictors of ARDS included use of pressors, sepsis, and obesity.

The purpose of this study was to prospectively evaluate a protocol that assesses the efficacy and sensitivity of clinical examination in complement with computed tomographic (CT) scan in screening for cervical spine (c-spine) injury. ⋯ In awake and alert blunt trauma patients, clinical examination is a sensitive screening method for c-spine injury. Clinical examination allows for the majority of blunt trauma patients to have their c-spines cleared safely without radiologic screening. Clinical examination in complement with CT scan is a sensitive and an effective method for identification of c-spine injury in awake and alert patients with symptoms of c-spine injury. CT scan is the sensitive and effective test for screening and diagnosis of c-spine injury in blunt trauma patients with altered mental status.

Currently, specific triage criteria, such as blood pressure, respiratory status, Glasgow Coma Scale, and mechanism of injury are used to categorize trauma patients and prioritize emergency department (ED) and trauma team responses. It has been demonstrated in previous literature that an abnormal shock index (SI = heart rate [HR]/systolic blood pressure, >0.9) portends a worse outcome in critically ill patients. Our study looked to evaluate the SI calculated in the field, on arrival to the ED, and the change between field and ED values as a simple and early marker to predict mortality in traumatically injured patients. ⋯ Trauma patients with SI >0.9 have higher mortality rates. An increase in SI from the field to the ED may predict higher mortality. The SI may be a valuable addition to other ED triage criteria currently used to activate trauma team responses.

The objective of this study was to analyze autopsy findings after blunt traumatic deaths to identify the incidence of cardiac injuries and describe the patterns of associated injuries. ⋯ Cardiac injury is a common autopsy finding after blunt traumatic fatalities, with the majority of deaths occurring at the scene. Patients with cardiac injuries are at significantly increased risk for associated thoracic and intra-abdominal injuries.
