To compare accelerational forces to the head in high school-level football, hockey, and soccer athletes. ⋯ Peak accelerations as measured at the surface of the head were 160 to 180% greater from heading a soccer ball than from routine (noninjurious) impacts during hockey or football, respectively. The effect of cumulative impacts at this level may lead to neurologic sequelae.

Prehospital resuscitation with phenylephrine in uncontrolled hemorrhagic shock and brain injury.
Hypotension doubles the adverse outcome of severe brain injury (BI). This finding is thought to be due to secondary ischemia caused by cerebral hypoperfusion. Aggressive prehospital fluid resuscitation in BI is advocated to maintain mean arterial pressure (MAP). Increasing MAP by prehospital fluid resuscitation before control of hemorrhage is thought to increase blood loss and reduce survival. We hypothesized that vasoconstrictor treatment of uncontrolled hemorrhage would increase MAP, reduce hemorrhage volume, and decrease the extent of BI compared with delayed fluid resuscitation (DR) or resuscitation with Ringer's lactate (RL). ⋯ Phen improves MAP and systemic and cerebral perfusion pressure in the prehospital phase but does not reduce secondary neuronal ischemia. RL restores cerebral blood flow earlier and is associated with less secondary ischemia than either Phen or DR in this model. These data suggest that prehospital infusion of RL in patients with BI and shock is warranted and decreases secondary ischemia.

Death from trauma frequently comes without forewarning. Relating the news of death to the family is often the responsibility of trauma surgeons. The purpose of this study was to investigate the key characteristics and methods of delivering bad news from the perspective of surviving family members. ⋯ The attitude of the news-giver, combined with clarity of the message and the time, privacy, and knowledge to answer questions are the most important aspects of giving bad news. This information should be incorporated into resident training.

Comparative Study
Comparison of various hemoglobin polyoxyethylene conjugate solutions as resuscitative fluids after hemorrhagic shock.
Previous research suggested that splanchnic hypoperfusion occurs after resuscitation with certain acellular hemoglobin solutions. We examined the influence of maltose content and oxygen affinity on resuscitation with various hemoglobin polyoxyethylene conjugate solutions after hemorrhage. ⋯ Vasoconstriction occurred in all groups but was more severe in the low P50 + 8% maltose group. Maltose-containing solutions caused respiratory acidosis, decreased pHi, and histologic evidence of mucosal injury. Pyridoxalated hemoglobin polyoxyethylene conjugate without maltose was a superior resuscitation solution in this swine model.
