Comparative Study
Motion in the unstable cervical spine during hospital bed transfers.
Hospital bed transfers, moves to examination room, X-ray, hospital bed, and/or surgery, have the potential of causing harm to a patient with an unstable cervical spine. This study evaluated motion generated in an unstable segment of the cervical spine during hospital bed transfers. A secondary goal purpose was to assess reduction in cervical motion using three collars and a no collar condition. ⋯ Bed transfers made with a lateral transfer device seem to be as safe as those made by the lift and slide manual transfer. None of the collars tested were significantly better at preventing cervical spine motion during a transfer, but each allowed less movement than no collar.

Arterialized venous flaps can be useful for hand/digit reconstruction, providing very thin skin coverage. However, their popularity has been limited by concerns over poor peripheral perfusion and severe congestion, which may be to be due to unrestricted arteriovenous shunting and pressurization of the efferent vein. To mitigate these problems, we design our flaps to restrict shunting. This report describes our clinical experience with these techniques. ⋯ Restriction of arteriovenous shunting enhances peripheral perfusion and decreases congestion of venous flaps, thereby improving reliability and utility for hand/digit reconstruction.

Trauma center designation correlates with functional independence after severe but not moderate traumatic brain injury.
The mortality of traumatic brain injury (TBI) continues to decline, emphasizing functional outcomes. Trauma center designation has been linked to survival after TBI, but the impact on functional outcomes is unclear. The objective was to determine whether trauma center designation influenced functional outcomes after moderate and severe TBI. ⋯ ACS trauma center designation is significantly associated with FI and IE after severe, but not moderate TBI. Prospective study is warranted to verify and explore factors contributing to this discrepancy.

Cranioplasty after postinjury decompressive craniectomy: is timing of the essence?
The appropriate timing of cranioplasty after decompressive craniectomy for trauma is unknown. Potential benefits of delayed intervention (>6 weeks) for reducing the risk of infection must be balanced by persistent altered cerebrospinal fluid dynamics leading to hydrocephalus. We reviewed our recent 5-year experience in an effort to improve patient throughput and develop a rational decision making plan. ⋯ In our experience, the prior practice of delayed cranioplasty (3-6 months postdecompressive craniectomy), requiring repeat hospital admission, does not seem to lower postcranioplasty infection rates nor the need for cerebrospinal fluid diversion procedures. Our current practice emphasizes cranioplasty during the initial hospital admission, as soon as there is resolution on computed tomography scan of brain swelling outside of the cranial vault with concurrent clinical examination. This occurs as early as 2 weeks postcraniectomy and should lower the overall cost of care by eliminating the need for additional hospital admissions.

Two prospective randomized trauma trials have shown recombinant factor VIIa (rFVIIa) to be safe and to decrease transfusion requirements. rFVIIa is presently used in 22% of massively transfused civilian trauma patients. The US Military has used rFVIIa in combat trauma patients for five years, and two small studies of massively transfused patients described an association with improved outcomes. This study was undertaken to assess how deployed physicians are using rFVIIa and its impact on casualty outcomes. ⋯ In military casualties, rFVIIa is used in the most severely injured patients based on physician selection rather than on guideline criteria. Use of rFVIIa is not associated with an improvement in survival or an increase in complications. The undetected bias of physician selection of patients for treatment with rFVIIa, likely, has an impact on case matching to achieve equivalence similar to that of randomized control studies. This inability to match populations, thus, prevents definitive interpretation of this study and others studies of similar design. This problem emphasizes the need to develop entry criteria to identify patients who could potentially benefit from use of rFVIIa and the need to subsequently perform efficacy studies.
