High-level falls are associated with multiple injuries and are often difficult to evaluate. Age may be an important factor determining the anatomic distribution and severity of injuries and outcome. There is little work published on this subject. Our objective was to evaluate the effect of age on the incidence and severity of specific organ injuries and survival outcome after high-level falls. ⋯ Age is an important variable in determining the nature and severity of injuries after high-level falls. Spinal injuries are very common in all age groups older than 14 years.

Orbital fractures associated with head trauma are not always easy to diagnose. The real incidence of such fractures is unknown. The aim of this study was to evaluate the usefulness of routine primary computed tomographic (CT) scanning for diagnosis of orbital fractures in head trauma patients. ⋯ CT scan of the orbits is indicated for any head trauma patient who presents either one or more symptoms directly related to an orbital fracture or just isolated blepharohematoma. CT scan of the orbits is not indicated in asymptomatic head trauma patients. Inclusion of the orbits in the scanning is recommendable only if a CT scan is already being obtained for a head injury. Clinical follow-up is important to detect any late-appearing symptoms. Accurate clinical examination still plays a crucial role in the diagnosis of orbital fractures.

Controversy and speculation exist regarding intracranial pressure (ICP) changes produced by various combinations of rapid sequence intubation (RSI) agents. In this pilot study, we sought to develop a swine model to investigate these changes in classic RSI. ⋯ The model is effective. It enables investigators to examine the aggregate ICP effects of combinations of RSI medications. RSI regimens with paralysis produced threefold increases in peak ICP change compared with the sedation-only regimen. Pretreatment agents did not affect ICP changes. Future investigations can examine other agents and add experimental manipulation of ICP to simulate head injury physiology. Additional parameters including cerebral metabolism and/or oxygenation may also be explored.
