RESUMO
BACKGROUND: Prolonged emergency department (ED) stays correlate with negative outcomes in critically ill nontrauma patients. This study sought to determine the effect of ED length of stay (LOS) on trauma patients. MATERIALS AND METHODS: Two hundred forty-one trauma patients requiring direct intensive care unit (ICU) admission were identified. Patients requiring immediate operative intervention were excluded. Odds ratios (ORs) of outcomes for patients transferred to ICU in ≤90 min were compared with patients transferred in >90 min, adjusting for Injury Severity Score (ISS). RESULTS: One hundred two of 241 patients (42%) were transferred to the ICU in ≤90 min. Increased ED LOS was associated with decreased complications (OR 0.545, 95% confidence interval 0.312-0.952). Although the result was not statistically significant, patients with an ISS >15 were less likely to have long ED stays (OR 0.725, 95% CI 0.407-1.290). No significant difference was seen in mortality. No difference in duration of intubation was observed for patients intubated in the ED versus the ICU. For the subgroup with ISS ≤15, there was a significant decrease in ICU LOS for patients who remained in the ED >90 min (5.5 d versus 2.7 d, P = 0.02). No other differences in LOS were identified. CONCLUSIONS: In a mature trauma center with standardized activation protocols and focused resource allocation in the ED trauma bay, trauma activation and subsequent management appear to mitigate the negative effects of prolonged ED LOS seen in other critically ill populations.

BACKGROUND: This pilot assessed transfusion requirements during resuscitation with whole blood followed by standard component therapy (CT) versus CT alone, during a change in practice at a large urban Level I trauma center. METHODS: This was a single-center prospective cohort pilot study. Male trauma patients received up to 4 units of cold-stored low anti-A, anti-B group O whole blood (LTOWB) as initial resuscitation followed by CT as needed (LTOWB + CT). A control group consisting of women and men who presented when LTOWB was unavailable, received CT only (CT group). Exclusion criteria included antiplatelet or anticoagulant medication and death within 24 hours. The primary outcome was total transfusion volume at 24 hours. Secondary outcomes were mortality, morbidity, and intensive care unit- and hospital-free days. RESULTS: Thirty-eight patients received LTOWB, with a median of 2.0 (interquartile range [IQR] 1.0-3.0) units of LTOWB transfused. Thirty-two patients received CT only. At 24 hours after presentation, the LTOWB +CT group had received a median of 2,138 mL (IQR, 1,275-3,325 mL) of all blood products. The median for the CT group was 4,225 mL (IQR, 1,900-5,425 mL; p = 0.06) in unadjusted analysis. When adjusted for Injury Severity Score, sex, and positive Focused Assessment with Sonography for Trauma, LTOWB +CT group patients received 3307 mL of blood products, and CT group patients received 3,260 mL in the first 24 hours (p = 0.95). The adjusted median ratio of plasma to red cells transfused was higher in the LTOWB + CT group (0.85 vs. 0.63 at 24 hours after admission; p = 0.043. Adjusted mortality was 4.4% in the LTOWB + CT group, and 11.7% in the CT group (p = 0.19), with similar complications, intensive care unit-, and hospital-free days in both groups. CONCLUSION: Beginning resuscitation with LTOWB results in equivalent outcomes compared with resuscitation with CT only. LEVEL OF EVIDENCE: Therapeutic (Prospective study with 1 negative criterion, limited control of confounding factors), level III.

BACKGROUND: Whole blood (WB) transfusion is a promising alternative to component therapy in hemostatic resuscitation. Use of banked WB requires filtration of white blood cells (leukoreduction) and an established shelf life during which WB retains coagulant capacities. The goal of this study was to define the time course of coagulation stability in leukoreduced compared to unfiltered WB under standard refrigeration conditions. METHODS: Twelve WB units were donated by healthy volunteers after routine screening. Five units underwent standard leukocyte filtration and five did not. Two units were aliquoted into filtered and unfiltered samples, with platelets added to each sample on day 14. Units were stored at 4°C and sampled on days 0, 1, 2, 3, 4, 5, 6, 7, 10, 14, 21, 28, and 35 for immediate thromboelastography (TEG) analysis, and centrifuged and stored at -80°C for later calibrated automated thrombogram and coagulation factor assays. RESULTS: K-dependent factors and fibrinogen were low normal, decreased slightly over 35 days and were similar between unfiltered and filtered units. Labile factors were better preserved in filtered units, although unfiltered units did not show impaired coagulation over 35 days. Filtered blood had delayed clot initiation on days 0, 1, and 2 as measured by TEG R (p < 0.021); slower clot progression (TEG α-angle) on days 0, 1, 2, 3, 4, 5, and 6 (p < 0.023); weaker final clot (TEG MA) on all days (p < 0.0001). Thrombin generation was delayed on day 28 (p = 0.046) and decreased on days 10, 21, 28, and 35 (p < 0.034). Addition of platelets to filtered WB rescued TEG MA. CONCLUSION: Filtered WB had decreased functional clotting capacity and thrombin generation and may not be suitable for hemostatic resuscitation as the sole blood product. LEVEL OF EVIDENCE: Therapeutic, level IV.

The objective of this study was to evaluate usage and outcomes of emergency laparoscopic versus open surgery at a single tertiary academic center. Over a three-year period 165 patients were identified retrospectively using National Surgical Quality Improvement Program results. Appendectomies and cholecystectomies were excluded. Open and laparoscopic approaches were compared regarding preoperative and operative characteristics, the development of postoperative complications, 30-day mortality, and length of hospital stay. Indications for operation were similar between groups. Patients who underwent open surgery had more severe comorbidities and higher ASA class. Laparoscopy was associated with reduced complication rates, operative time, length of stay, and discharges to skilled nursing facilities on univariate analysis. In a multivariate model, surgical approach was not associated with the development of complications. Older age, dependent status, and dyspnea were predictors of conversion from attempted laparoscopic to open approaches.
