Multicenter Study Clinical Trial
Surgeon-performed bedside organ assessment with sonography after trauma (BOAST): a pilot study from the WTA Multicenter Group.
Although nonoperative management of solid organ injuries is a well-accepted practice, a rapid method to assess the progression of the injury, the early development of organ-related complications, and the frequency with which follow-up computed tomography (CT) scans are needed has yet to be determined. The use of ultrasound in this setting may provide information that would improve the rate of organ salvage and decrease the patient's morbidity. The objectives of this study were to determine whether surgeons could successfully use a bedside organ assessment with sonography after trauma (BOAST) examination to: (1) detect a solid organ injury; and (2) assess for changes in the size of the organ injury, an increase or decrease in hemoperitoneum, and the development of organ-related complications. ⋯ (1) BOAST has limitations in identifying solid organ injuries, especially those that are lower grade; (2) the US heme score is a valuable adjunct to the clinical examination in following patients with high-grade solid organ injuries and a dropping hemoglobin; and (3) although uncommon, organ-related complications may be identified using BOAST.

Recovery at one year following isolated traumatic brain injury: a Western Trauma Association prospective multicenter trial.
Age has been shown to be a primary determinant of survival following isolated traumatic brain injury (TBI). We have previously reported that patients > or =65 years who survived mild TBI have decreased functional outcome at 6 months compared with younger patients. The purpose of this study was to further investigate the effect of age on outcome at 1 year in all patients surviving isolated TBI. ⋯ Older patients following isolated TBI have poorer functional status at discharge and make less improvement at 1 year compared with all other patients. These worse outcomes occur despite what appears to be less severe TBI as measured by a higher GCS upon admission. Differences in outcome begin to appear even in patients between 45 and 59 years. Further investigations with more detailed outcome instruments are required to better understand the qualitative limitations of a patient's recovery and to devise strategies to maximize functional improvement following TBI. Age is an exceedingly important parameter affecting recovery from isolated TBI.

The classical "Kellie-Monroe" doctrine considering the intracranial volume to be a closed system that is confined within the nearly rigid skull, conserves different mass, and has equal vascular inflow and outflow. Several experimental and clinical studies have given evidence that this is not entirely true from the (patho)physiologic point of view, even so our understanding of this phenomenon is incomplete. ⋯ This has the advantage of great practical use on the one hand and allows the demonstration of relevant intercompartimental intracranial pressure differences. In addition, these ICP differences can be revealed to different ICP compartments and to its relationship to CBF. Special reference is given to determine appropriate forms for the nonconstant resistance and compliance parameters.

The failure of nonoperative management in pediatric solid organ injury: a multi-institutional experience.
Nonoperative management (NOM) is the accepted treatment of most pediatric solid organ injuries (SOI) and, is typically successful. We sought to elucidate predictors of, and the time course to, failure in the subset of children suffering SOI who required operative intervention. ⋯ Failure of NOM is un common (5%) and typically occurs within the first 12 hours after injury. Failure is associated with injury severity and multiplicity, as well as isolated pancreatic injuries.

Cervical spinal cord injury (SCI) has a well-established association with a high risk of respiratory complications. We sought to determine whether high-thoracic (HT) SCI was associated with a similar increased risk of respiratory complications and death. ⋯ Compared with patients with low thoracic SCI or thoracolumbar fractures, patients with HT-SCI have an increased risk of pneumonia and death. Respiratory complications significantly increase the mortality risk in less severely injured patients. The current findings suggest that HT-SCI patients warrant intensive monitoring and aggressive pulmonary care and attention, similar to that given for patients with cervical SCI.
