Traumatic abdominal wall hernia and Morel-Lavallee lesion in a pediatric patient.

Traumatic abdominal wall hernias and abdominal Morel-Lavallee lesions rarely occur in blunt abdominal trauma. There are only a few documented cases of these occurring simultaneously, especially in the pediatric population. We report a case of a 15-year-old boy with a concomitant traumatic abdominal wall hernia and Morel-Lavallee lesions. Abdominal wall reconstruction was performed successfully via the collaboration of trauma, minimally invasive surgery, and plastic surgery teams.

Impact of Trauma-Certified Registered Nurse Anesthetists Team on Intra-Operative Resuscitation and Postoperative Outcomes of Trauma Patients.

A Trauma Certified Registered Nurse Anesthetists Team (TCT) was created and trained to provide trauma-focused anesthesia and resuscitation. The purpose of this study was to examine patient outcomes after implementation of TCT. We conducted retrospective analyses of trauma patients managed with surgical intervention from March to December 2015. During the first five months, patients managed before the development of TCT were grouped No-TCT, patients managed after were grouped TCT. To assess outcomes, we used hospital and intensive care unit length of stay, ventilator days, and a validated 10-point intraoperative Apgar score (IOAS). IOAS is calculated using the estimated blood loss, lowest heart rate, and lowest mean arterial pressure during surgery. Higher IOAS are associated with significantly decreased complications and mortality after surgery. We used t test and nonparametric tests for analyses. Fifty two patients were included (mean age 39 years, 75% male; 46.2% managed with TCT). Patients in the No-TCT group had significantly lower use of vasopressors (0.019), lower mean IOAS (P = 0.02), and spent more days on ventilator (P = 0.005) than patients in the TCT. These results suggest that trauma centers should take into consideration implementation of TCT to improve intraoperative and overall outcomes.

Implications of the Trauma Quality Improvement Project inclusion of nonsurvivable injuries in performance benchmarking.

BACKGROUND: The Trauma Quality Improvement Project (TQIP) uses an injury prediction model for performance benchmarking. We hypothesize that at a Level I high-volume penetrating trauma center, performance outcomes will be biased due to inclusion of patients with nonsurvivable injuries. METHODS: Retrospective chart review was conducted for all patients included in the institutional TQIP analysis from 2013 to 2014 with length of stay (LOS) less than 1 day to determine survivability of the injuries. Observed (O)/expected (E) mortality ratios were calculated before and after exclusion of these patients. Completeness of data reported to TQIP was examined. RESULTS: Eight hundred twenty-six patients were reported to TQIP including 119 deaths. Nonsurvivable injuries accounted 90.9% of the deaths in patients with an LOS of 1 day or less. The O/E mortality ratio for all patients was 1.061, and the O/E ratio after excluding all patients with LOS less than 1 day found to have nonsurvivable injuries was 0.895. Data for key variables were missing in 63.3% of patients who died in the emergency department, 50% of those taken to the operating room and 0% of those admitted to the intensive care unit. Charts for patients who died with LOS less than 1 day were significantly more likely than those who lived to be missing crucial. CONCLUSION: This study shows TQIP inclusion of patients with nonsurvivable injuries biases outcomes at an urban trauma center. Missing data results in imputation of values, increasing inaccuracy. Further investigation is needed to determine if these findings exist at other institutions, and whether the current TQIP model needs revision to accurately identify and exclude patients with nonsurvivable injuries. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

Multi-institutional analysis of neutrophil-to-lymphocyte ratio (NLR) in patients with severe hemorrhage: A new mortality predictor value.

BACKGROUND: The neutrophil/lymphocyte ratio (NLR) has been associated as a predictor for increased mortality in critically ill patients. We sought to determine the relationship between NLR and outcomes in adult trauma patients with severe hemorrhage requiring the initiation of massive transfusion protocol (MTP). We hypothesized that the NLR would be a prognostic indicator of mortality in this population. METHODS: This was a multi-institutional retrospective cohort study of adult trauma patients (≥18 years) with severe hemorrhage who received MTP between November 2014 and November 2015. Differentiated blood cell counts obtained at days 3 and 10 were used to obtain NLR. Receiver operating characteristic (ROC) curve analysis assessed the predictive capacity of NLR on mortality. To identify the effect of NLR on survival, Kaplan-Meier (KM) survival analysis and Cox regression models were used. RESULTS: A total of 285 patients with severe hemorrhage managed with MTP were analyzed from six participating institutions. Most (80%) were men, 57.2% suffered blunt trauma. Median (IQR) age, Injury Severity Score, and Glasgow Coma Scale were 35 (25-47), 25 (16-36), and 9 (3-15), respectively. Using ROC curve analysis, optimal NLR cutoff values of 8.81 at day 3 and 13.68 at day 10 were calculated by maximizing the Youden index. KM curves at day 3 (p = 0.05) and day 10 (p = 0.02) revealed an NLR greater than or equal to these cutoff values as a marker for increased in-hospital mortality. Cox regression models failed to demonstrate an NLR over 8.81 as predictive of in-hospital mortality at day 3 (p = 0.056) but was predictive for mortality if NLR was greater than 13.68 at day 10 (p = 0.036). CONCLUSIONS: NLR is strongly associated with early mortality in patients with severe hemorrhage managed with MTP. Further research is needed to focus on factors that can ameliorate NLR in this patient population. LEVEL OF EVIDENCE: Prognostic study, level III.
