Panamerican Trauma Society: The first three decades
Panamerican Trauma Society was born 30 years ago with the mission of improving trauma care in the Americas by exchange of ideas and concepts and expanding knowledge of trauma and acute illness. The authors, immediate-past leaders of the organization, review the evolution of this assembly of diverse cultures and nationalities
Obesity Does Not Increase Mortality after Emergency Surgery
Objective. The aim of this study is to evaluate the impact of obesity on patient outcomes after emergency surgery. Methods. A list of all patients undergoing emergent general surgical procedures during the 12 months ending in July 2012 was obtained from the operating room log. A chart review was performed to obtain the following data: patient characteristics (age, gender, BMI, and preexisting comorbidities), indication for surgery, and outcomes (pulmonary embolus (PE), deep venous thrombosis (DVT), respiratory failure, ICU admission, wound infection, pneumonia, and mortality). Obesity was defined as a BMI over 25. Comparisons of outcomes between obese and nonobese patients were evaluated using Fischer’s exact test. Predictors of mortality were evaluated using logistic regression. Results. 341 patients were identified during the study period. 202 (59%) were obese. Both groups were similar in age (48 for obese versus 47 for nonobese, ). Obese patients had an increased incidence of diabetes, (27% versus 7%, ), hypertension (52% versus 34%, ), and sleep apnea (0% versus 5%, ). There was a statistically significant increased incidence of postoperative wound infection (obese 9.9% versus nonobese 4.3%, ) and ICU admission (obese 58% versus nonobese 42%, ) among the obese patients. Obesity alone was not shown to be a significant risk factor for mortality. Conclusions. A higher BMI is not an independent predictor of mortality after emergency surgery. Obese patients are at a higher risk of developing wound infections and requiring ICU admission after emergent general surgical procedure
DVT Surveillance Program in the ICU: Analysis of Cost-Effectiveness
Background
Venous Thrombo-embolism (VTE – Deep venous thrombosis (DVT) and/or pulmonary embolism (PE) – in traumatized patients causes significant morbidity and mortality. The current study evaluates the effectiveness of DVT surveillance in reducing PE, and performs a cost-effectiveness analysis. Methods
All traumatized patients admitted to the adult ICU underwent twice weekly DVT surveillance by bilateral lower extremity venous Duplex examination (48-month surveillance period – SP). The rates of DVT and PE were recorded and compared to the rates observed in the 36-month pre-surveillance period (PSP). All patients in both periods received mechanical and pharmacologic prophylaxis unless contraindicated. Total costs – diagnostic, therapeutic and surveillance – for both periods were recorded and the incremental cost for each Quality Adjusted Life Year (QALY) gained was calculated. Results
4234 patients were eligible (PSP – 1422 and SP – 2812). Rate of DVT in SP (2.8%) was significantly higher than in PSP (1.3%) – p Conclusions
Surveillance of traumatized ICU patients increases DVT detection and reduces PE incidence. Costs in terms of QALY gained compares favorably with other interventions accepted by society

Predictors of mortality were evaluated using logistic regression. Results. 341 patients were identified during the study period. 202 (59%) were obese. Both groups were similar in age (48 for obese versus 47 for nonobese, P=0.42). Obese patients had an increased incidence of diabetes, (27% versus 7%, P<0.05), hypertension (52% versus 34%, P<0.05), and sleep apnea (0% versus 5%, P<0.05). There was a statistically significant increased incidence of postoperative wound infection (obese 9.9% versus nonobese 4.3%, P<0.05) and ICU admission (obese 58% versus nonobese 42%, P=0.01) among the obese patients. Obesity alone was not shown to be a significant risk factor for mortality. Conclusions. A higher BMI is not an independent predictor of mortality after emergency surgery. Obese patients are at a higher risk of developing wound infections and requiring ICU admission after emergent general surgical procedure

Military civilian partnerships: International proposals for bridging the Walker Dip.
The Walker Dip refers to the cycle of the improvement of care for the battle injured soldier over the course of a conflict, followed by the decline in the skills needed to provide this care during peacetime, and the requisite need to relearn those skills during the next conflict. As the operational tempo of the conflicts in Afghanistan and Iraq has declined, concerns have arisen regarding whether US military surgeons are prepared to meet the demands of future conflicts. This problem is not unique to the US military, and allied nations have taken creative steps to address the Walker Dip in their own surgical communities. A panel entitled "Military and Civilian Trauma System Integration: Where Have We Come; Where Are We Going and What Can We Learn from Our International Partners" at the 2018 American Association for the Surgery of Trauma meeting brought together a cadre of civilian and military surgeons with experience in this area. The efforts described involved the creation of a new trauma training program in Doha, Qatar, the military civilian partnership in the Netherlands, and the steps taken to address the deficit of penetrating trauma in Sweden. This article focuses on the lessons that can be learned from our allied partners to assure readiness for deployment among military surgeons.

Triage Protocol for Rib Fracture Patients: Clinical Function Is More Important Than Age and Anatomy
Who Needs to Be in the Intensive Care Unit? Potential Cost Savings with an Improved Triage Algorithm for Rib Fractures
Effects of a novel low volume resuscitation solutions on coagulation and platelet function.
BackgroundNovel crystalloid solutions containing polyethylene glycol polymers (PEG-20k) produce dramatic resuscitation effects but dose-dependently produce a hypocoagulative state. The objective of this study was to examine possible mechanisms of this effect. Based on previous thromboelastography data, we hypothesize the effect is largely due to platelet interactions with the polymers.MethodsWhole citrated blood from healthy volunteers was diluted ex-vivo 10% with crystalloids and tested for coagulation and platelet function. The specific tests included prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen and von Willebrand factor (vWf) activity, thrombin generation, thromboelastography with and without platelet mapping, platelet flow cytometry, and erythrocyte sedimentation rate.FindingsFibrinogen and vWF activities, PT, and aPTT were not affected by PEG-20k dilutions. Thrombin activity was mildly suppressed with PEG-20k (TTP- 20%). Platelet mapping demonstrated significantly greater % inhibition of both ADP and arachidonic acid-induced platelet aggregation with PEG-20k, but direct ADP-activated gpIIa/IIIb (PAC1) and P-selectin (CD62P) binding site expression was not altered. Mild dose-dependent suppression of TEG-MA was seen with PEG-20k using platelet poor plasma. Erythrocyte Sedimentation Rates (ESR) were dramatically accelerated after dilution with 10% PEG-20k, which was competitively blocked by smaller PEG polymers, suggesting nonspecific PEG-20k cell binding effects.ConclusionsPEG-20k creates a mild hypocoagulative state in whole blood at concentrations ≥10%, which may be due to platelet-PEG interactions at the IIb/IIIa interface with lesser effects on fibrin polymerization. This interaction may cause a functional thrombasthenia induced by nonspecific platelet surface passivation by the PEG polymer
