Randomized Controlled Trial Multicenter Study Comparative Study
Global differences in causes, management, and survival after severe trauma: the recombinant activated factor VII phase 3 trauma trial.
Little is known about international variation in mortality after severe trauma. This study examines variation in mortality, injury severity, and case management among countries from a recent prospective multinational trauma trial. ⋯ Considering international variation in mortality when designing or interpreting results from multinational trauma studies is important. Significant differences in mortality persisted between patients from different countries after case mix and case management adjustment. Adherence to clinical guidelines was associated with improved survival. Stratification, case mix adjustment, and use of guidelines on damage control surgery, transfusion, and ventilation may mitigate country-driven variation in mortality.

Smoking in trauma patients: the effects on the incidence of sepsis, respiratory failure, organ failure, and mortality.
There is a high percentage of smokers among trauma patients. Cigarette smoking has been associated with the development of acute lung injury and the adult respiratory distress syndrome in critically ill patients. It is also known that nicotine exerts immunosuppressive and anti-inflammatory effects with chronic use. Trauma patients who are smokers usually go through acute nicotine withdrawal after the traumatic event and during their stay in ICU. How the smoking status and acute nicotine withdrawal affect outcomes after trauma is unknown. This question was addressed in this study by analyzing the incidence of sepsis, septic shock and multiple organ dysfunction syndrome, and other outcomes in smoking and nonsmoking trauma patients. ⋯ The smoking status plays a minimal role in the outcome of healthy trauma patients. This suggests that the acute nicotine withdrawal that usually occurs in critically ill patients has no clinically significant implications after injury.

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.

Ever-increasing numbers of in-house acute care surgeons and competition for operating room time during normal daytime business hours have led to an increased frequency of nonemergent general and vascular surgery procedures occurring at night when there are fewer residents, consultants, nurses, and support staff available for assistance. This investigation tests the hypothesis that patients undergoing such procedures after hours are at increased risk for postoperative morbidity and mortality. ⋯ Patients undergoing nonemergent general and vascular surgery procedures at night in an academic medical center do not seem to be at increased risk for postoperative morbidity or mortality. Performing nonemergent procedures at night seems to be a safe solution for daytime overcrowding of operating rooms.

It remains to be determined whether spine-targeted computed tomography (thoracolumbar spine computed tomography [TLS-CT]) images and visceral organ-targeted CT (abdominopelvic [AP]-CT) images are comparable for the evaluation of thoracolumbar spinal fractures using 16-channel multidetector row CT. The elimination of an additional spine-targeted CT protocol would substantially reduce time, the storage burden, and potential patient radiation exposure. ⋯ Sixteen-channel multidetector row CT images reconstructed using a soft algorithm and a wide display FOV that cover the entire abdomen using a visceral organ-targeted protocol with 1.5-mm collimation are sufficient for the evaluation of spine fractures in trauma patients, given that multiplanar-reformatted images are provided.
