Despite research linking chemical and physical restraints to negative outcomes including unplanned intubations and psychological distress, there is little guidance for their use in the care of trauma patients. We used institutional data to describe recent trends in chemical and physical restraint in the emergency department evaluation and treatment of trauma patients and to identify characteristics associated with their use. ⋯ In this institutional study, nearly one-in-twelve trauma patients were restrained during emergency department evaluation and treatment. Restraint utilization increased during the study driven primarily by increases in ketamine and restraints utilized during trauma bay evaluation and resuscitation. Future research should assess the generalizability of these findings. It is important that rigorous guidelines are established to ensure the safe and effective use of restraints in trauma.

Older patients are expected to comprise 40 % of trauma admissions in the next 30 years. The use of whole blood (WB) has shown promise in improving mortality while lowering the utilization of blood products. However, the use of WB in older trauma patients has not been examined. The objective of our study is to determine the safety and efficacy of a WB first transfusion strategy in injured older patients. ⋯ The use of WB in the older trauma patient appears safe, with mortality and complication rates comparable to component therapy. Blood product utilization is significantly less in those that are resuscitated with WB first.

Background : New strategies are needed to mitigate further tissue injury during traumatic limb ischemia in cases requiring damage control resuscitation (DCR). Little is known about the pathophysiology and injury course in acute limb ischemia (ALI) with DCR in polytraumatized casualties. We therefore investigated the effects of therapeutic limb hypothermia in a swine model of ALI and DCR. ⋯ Mean nerve histology scores did not differ between the 5°C and paired control limbs, or between the mean muscle and nerve histology scores of the 15°C and paired control limbs. Conclusion : Cooling to 15°C significantly reduced local tissue metabolites compared to paired controls, while producing no significant increase in histologic damage, whereas cooling to 5°C increased histologic muscle damage. These results suggest an approach to prevention of ischemic injury through local hypothermia but warrant further functional testing.
