Comparative Study
Predicting survival, length of stay, and cost in the surgical intensive care unit: APACHE II versus ICISS.
Risk stratification of patients in the intensive care unit (ICU) is an important tool because it permits comparison of patient populations for research and quality control. Unfortunately, currently available scoring systems were developed primarily in medical ICUs and have only mediocre performance in surgical ICUs. Moreover, they are very expensive to purchase and use. We conceived a simple risk-stratification tool for the surgical ICU that uses readily available International Classification of Diseases, Ninth Revision, codes to predict outcome. Called ICISS (International Classification of Disease Illness Severity Score), our score is the product of the survival risk ratios (obtained from an independent data set) for all International Classification of Diseases, Ninth Revision, diagnosis codes. ⋯ Because ICISS is both more accurate and much less expensive to calculate than APACHE II score, ICISS should replace APACHE II score as the standard risk stratification tool in surgical ICUs.

To evaluate the functional outcome and return to work after suture of upper extremity nerves after low-velocity missile injury. ⋯ Nerve suture between the wrist and axilla and supplemental techniques achieve functional recovery in the majority of patients after missile injury with good expectations for return to work, except in combined median and ulnar nerve injuries.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Partial liquid ventilation decreases the inflammatory response in the alveolar environment of trauma patients.
Perflubron is a perfluorocarbon with unique physical characteristics. It has twice the density of water, allows free diffusion of O2 and CO2, is easily dispersed, and is insoluble. Thus, it can act as "liquid positive end-expiratory pressure" to recruit collapsed alveoli and improve oxygenation. Results of laboratory studies suggest that perflubron exerts an anti-inflammatory effect on alveolar cells. Limited clinical data in neonates and adults with severe acute respiratory distress syndrome are promising. We present a single institution's experience with partial liquid ventilation (PLV) in trauma patients compared with conventional mechanical ventilation (CMV) with particular attention to the alveolar inflammatory response. ⋯ Early institution of partial liquid ventilation is effective at reducing the alveolar inflammatory response. Perflubron exhibits an anti-inflammatory effect in the alveolar environment with reduction of proinflammatory IL-1 and IL-6 (possibly removing a stimulus for IL-10), white blood cell count, and protein capillary leak. PLV also reduces alveolar neutrophils independent of IL-8. Further characterization of this altered inflammatory response is necessary.

Review Case Reports
Seat belt-related injury to the common iliac artery: case report and review of the literature.
Blunt trauma to the common iliac artery is a rare phenomenon. Although seat belt injuries to the abdominal aorta and the carotid artery have been reported, there is only one previous report in the literature of seat belt injury to the common iliac artery. We report a case of common iliac arterial injury directly related to use of the lap belt and not associated with pelvic or lumbar fractures. The literature related to blunt trauma of the common iliac artery is reviewed.

The failure of therapies aimed at modulating systemic inflammatory response syndrome and decreasing multiple organ failure (MOF) has been attributed in part to the inability to identify early the population at risk. Our objective, therefore, was to develop predictive models for MOF at admission and at 12, 24 and 48 hours after injury. ⋯ Postinjury MOF can be predicted as early as 12 hours after injury. The APS-APACHE III added little to the predictive power of tissue injury, shock and host factors.
