Blunt SBI is infrequent and its diagnosis may be difficult, especially in the face of confounding variables. The purpose of this study was to evaluate methods for making the diagnosis of blunt SBI. ⋯ Alone or in combination, current diagnostic approaches lack sensitivity in the diagnosis of perforated SBI. Improvements in diagnostic methods and approaches are needed to ensure the prompt diagnosis of this uncommon but potentially devastating injury.

There is an absence of prospective data evaluating the impact of prehospital intubation in adult trauma patients. Our objectives were to determine the outcome of trauma patients intubated in the field who did not have an acutely lethal traumatic brain injury (death within 48 hours) compared with patients who were intubated immediately on arrival to the hospital. ⋯ Prehospital intubation is associated with a significant increase in morbidity and mortality in trauma patients with traumatic brain injury who are admitted to the hospital without an acutely lethal injury. A randomized, prospective study is warranted to confirm these results.

Blunt hollow viscus injury (HVI) is uncommon. No sufficiently large series has studied the prevalence of these injuries in blunt trauma patients. This study defines the prevalence of blunt HVI, in addition to the associated morbidity and mortality rates for this diagnosis on the basis of a series of over 275,000 trauma admissions. ⋯ HVI is a rare but deadly phenomenon. The high mortality rates reflect the severity of the HVI and associated injuries. HVI patients should be carefully monitored for related injuries and complications.

Comparative Study
Tissue oxygen monitoring during hemorrhagic shock and resuscitation: a comparison of lactated Ringer's solution, hypertonic saline dextran, and HBOC-201.
The ideal resuscitation fluid for the trauma patient would be readily available to prehospital personnel, universally compatible, effective when given in small volumes, and capable of reversing tissue hypoxia in critical organ beds. Recently developed hemoglobin-based oxygen-carrying solutions possess many of these properties, but their ability to restore tissue oxygen after hemorrhagic shock has not been established. We postulated that a small-volume resuscitation with HBOC-201 (Biopure) would be more effective than either lactated Ringer's (LR) solution or hypertonic saline dextran (HSD) in restoring baseline tissue oxygen tension levels in selected tissue beds after hemorrhagic shock. We further hypothesized that changes in tissue oxygen tension measurements in the deltoid muscle would reflect the changes seen in the liver and could thus be used as a monitor of splanchnic resuscitation. ⋯ HBOC-201 can be administered safely in small doses and compared favorably to resuscitation with HSD and LR solution in this prehospital model of hemorrhagic shock. HBOC-201 is significantly more effective than HSD and LR solution in restoring MAP and systolic blood pressure to normal values. Deltoid muscle PO2 reflects liver PO2 and thus may serve as an index of the adequacy of resuscitation in critical tissue beds.

Domestic violence (DV) has received increased recognition as a significant mechanism of injury. To improve awareness about DV at our institution, an educational program was presented to the departments of surgery and emergency medicine. Pre and posttests were given and improvement in knowledge was demonstrated. In addition, a screening question for DV was added to the trauma history and physical (H & P) form. This study was done to determine the long-term efficacy of these efforts in increasing recognition of DV and referral to social services in patients admitted to the trauma service. Recognition of DV and appropriate referral should be increased after education and change in H & P form. ⋯ DV is unrecognized and underreported. Efforts to improve recognition and reporting of DV events need to be ongoing. Screening for DV is not effectively done as part of the initial evaluation. Assessment for DV may be more appropriate as part of the tertiary survey.
