Clostridium (reclassified as " Clostridioides ") difficile infection (CDI) occurs as a chronic or an acute illness with intensity varying from mild to severe. Although most cases of CDI can be managed with antibiotics and supportive care, when the patient presents with fulminant disease, the early decision to perform surgery is imperative for survival. The current standard of care is the subtotal colectomy. However, loop ileostomy with vancomycin enemas delivered into the colonic mucosa has been described as a viable option on selected patients.
RESUMO
BACKGROUND: Smoke inhalation-associated acute lung injury (SI-ALI) is a major cause of morbidity and mortality in victims of fire tragedies. To date, there are no evidence-based guidelines on ventilation strategies in acute respiratory distress syndrome (ARDS) after smoke inhalation. We reviewed the existing literature for clinical studies of salvage mechanical ventilation (MV) strategies in patients with SI-ALI, focusing on mortality and pneumonia as outcomes. METHODS: A systematic search was designed in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Risk of bias assessment was performed using the Newcastle-Ottawa Quality Assessment Scale (NOS; 0 to 9 stars), with a score ≥7 being the threshold for inclusion in the meta-analysis. A systematic search strategy was used to search 10 databases. Clinical studies were included in which patients: (1) experienced smoke inhalation, (2) treated with MV, and (3) described a concurrent or historical control group. RESULTS: A total of 226 potentially relevant studies were identified, of which 7 studies on high-frequency percussive ventilation (HFPV) met inclusion criteria. No studies met inclusion for meta-analysis (NOS ≥ 7). In studies comparing HFPV to conventional mechanical ventilation (CMV), mortality and pneumonia incidence improved in 3 studies and remained unchanged in 3 others. No change in ventilator days or ICU length of stay was observed; however, oxygenation and work of breathing improved with HFPV. CONCLUSIONS: Mechanical ventilation in patients with SI-ALI has not been well studied. High-frequency percussive ventilation may decrease in-hospital mortality and pneumonia incidence when compared to CMV. The absence of "good" quality evidence precluded meta-analysis. Based upon low-quality evidence, there was a very weak recommendation that HFPV use may be associated with lower mortality and pneumonia rates in patients with SI-ALI. Given SI-ALI's unique underlying pathophysiology, and its potential implications on therapy, randomized controlled studies are required to ensure that patients receive the safest and most effective care. TRIAL REGISTRATION: The study was registered with PROSPERO International prospective register of systematic reviews (#47015).

BACKGROUND: Point-of-care sonography (POCS) has emerged as the screening modality of choice for suspected body trauma in many emergency departments worldwide. Its best known application is FAST (focused abdominal sonography for trauma). The technology is almost ubiquitously available, can be performed during resuscitation, and does not expose patients or staff to radiation. While many authors have stressed the high specificity of POCS, its sensitivity varied markedly across studies. This review aimed to compile the current best evidence about the diagnostic accuracy of POCS imaging protocols in the setting of blunt thoracoabdominal trauma. OBJECTIVES: To determine the diagnostic accuracy of POCS for detecting and excluding free fluid, organ injuries, vascular lesions, and other injuries (e.g. pneumothorax) compared to a diagnostic reference standard (i.e. computed tomography (CT), magnetic resonance imaging (MRI), thoracoscopy or thoracotomy, laparoscopy or laparotomy, autopsy, or any combination of these) in patients with blunt trauma. SEARCH METHODS: We searched Ovid MEDLINE (1946 to July 2017) and Ovid Embase (1974 to July 2017), as well as PubMed (1947 to July 2017), employing a prospectively defined literature and data retrieval strategy. We also screened the Cochrane Library, Google Scholar, and BIOSIS for potentially relevant citations, and scanned the reference lists of full-text papers for articles missed by the electronic search. We performed a top-up search on 6 December 2018, and identified eight new studies which may be incorporated into the first update of this review. SELECTION CRITERIA: We assessed studies for eligibility using predefined inclusion and exclusion criteria. We included either prospective or retrospective diagnostic cohort studies that enrolled patients of any age and gender who sustained any type of blunt injury in a civilian scenario. Eligible studies had to provide sufficient information to construct a 2 x 2 table of diagnostic accuracy to allow for calculating sensitivity, specificity, and other indices of diagnostic test accuracy. DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles, abstracts, and full texts of reports using a prespecified data extraction form. Methodological quality of individual studies was rated by the QUADAS-2 instrument (the revised and updated version of the original Quality Assessment of Diagnostic Accuracy Studies list of items). We calculated sensitivity and specificity with 95% confidence intervals (CI), tabulated the pairs of sensitivity and specificity with CI, and depicted these estimates by coupled forest plots using Review Manager 5 (RevMan 5). For pooling summary estimates of sensitivity and specificity, and investigating heterogeneity across studies, we fitted a bivariate model using Stata 14.0. MAIN RESULTS: We included 34 studies with 8635 participants in this review. Summary estimates of sensitivity and specificity were 0.74 (95% CI 0.65 to 0.81) and 0.96 (95% CI 0.94 to 0.98). Pooled positive and negative likelihood ratios were estimated at 18.5 (95% CI 10.8 to 40.5) and 0.27 (95% CI 0.19 to 0.37), respectively. There was substantial heterogeneity across studies, and the reported accuracy of POCS strongly depended on the population and affected body area. In children, pooled sensitivity of POCS was 0.63 (95% CI 0.46 to 0.77), as compared to 0.78 (95% CI 0.69 to 0.84) in an adult or mixed population. Associated specificity in children was 0.91 (95% CI 0.81 to 0.96) and in an adult or mixed population 0.97 (95% CI 0.96 to 0.99). For abdominal trauma, POCS had a sensitivity of 0.68 (95% CI 0.59 to 0.75) and a specificity of 0.95 (95% CI 0.92 to 0.97). For chest injuries, sensitivity and specificity were calculated at 0.96 (95% CI 0.88 to 0.99) and 0.99 (95% CI 0.97 to 1.00). If we consider the results of all 34 included studies in a virtual population of 1000 patients, based on the observed median prevalence (pretest probability) of thoracoabdominal trauma of 28%, POCS would miss 73 patients with injuries and falsely suggest the presence of injuries in another 29 patients. Furthermore, in a virtual population of 1000 children, based on the observed median prevalence (pretest probability) of thoracoabdominal trauma of 31%, POCS would miss 118 children with injuries and falsely suggest the presence of injuries in another 62 children. AUTHORS' CONCLUSIONS: In patients with suspected blunt thoracoabdominal trauma, positive POCS findings are helpful for guiding treatment decisions. However, with regard to abdominal trauma, a negative POCS exam does not rule out injuries and must be verified by a reference test such as CT. This is of particular importance in paediatric trauma, where the sensitivity of POCS is poor. Based on a small number of studies in a mixed population, POCS may have a higher sensitivity in chest injuries. This warrants larger, confirmatory trials to affirm the accuracy of POCS for diagnosing thoracic trauma.

INTRODUCTION: Limited transthoracic echocardiogram (LTTE) has been shown to be a useful tool in guiding resuscitation in adult trauma patients. Our hypothesis is that image-guided resuscitation in pediatric trauma patients with LTTE is feasible. METHODS: A retrospective chart review was performed on highest level pediatric trauma alerts (age 18 years or younger) at our level I trauma center during a 6-month period. Patients were divided into 2 groups as follows: those who had LTTE performed (LTTE group) and those who did not have LTTE performed (non-LTTE group). RESULTS: A total of 31 charts were reviewed; 4 patients were excluded because they died on arrival to the emergency department. Fourteen patients had LTTE performed (LTTE group); 13 patients did not have LTTE performed (non-LTTE group). There was no difference in mechanism of injury, age, injury severity score, weight, or intensive care unit admission between the groups. The LTTE group received significantly less intravenous fluid than the non-LTTE group (1.2 vs 2.3 L, P = 0.0013).Within the LTTE group, 8 patients had "full" inferior vena cava (IVC) and 6 patients had "empty" IVC. There was no difference in injury severity score between these subgroups (P = 0.1018). Less fluid was given in the group labeled with full IVC [1.1 L (0.8-1.2)] than the group with empty IVC [2.4 L (1.7-2.6)], P = 0.0005. Four of the 6 patients with "empty" IVC had a confirmed source of bleeding. CONCLUSIONS: Limited transthoracic echocardiogram can limit the amount of unnecessary crystalloid resuscitation given to pediatric trauma patients who are not hypovolemic.

Hemorrhagic shock leads to cell and tissue swelling and no reflow from compressed capillaries. Cell impermeants, including polyethylene glycol-20,000 (PEG-20k), reverse ischemia-induced cell swelling, extend low-volume resuscitation (LVR) time after shock, and increase tolerance to the low-volume state. The purpose of this study was to explore the mechanisms of action of PEG-20k containing LVR solutions. We hypothesized that PEG-20k acts as both an oncotic agent and an impermeant in the microcirculation, which moves water out of the space and into the capillaries to affect peripheral capillary filling and enhanced perfusion during the low-volume state. Rats were hemorrhaged until arterial lactate reached 9-10 mM/liter. Then, saline-based LVR solutions containing various impermeant materials were administered (10% blood volume). The LVR times for these solutions were determined by measuring the amount of time required for plasma lactate to climb back to 9 to 10 mM after LVR administration (low-volume tolerance). Capillary blood flow was measured by colored microspheres, and blood volume was measured by fluorescein isothiocyanate-labeled albumin dilution. Gluconate (impermeant), albumin (colloid), and PEG-20k (hybrid) increased LVR time over saline by 4-, 3-, and 8-fold, respectively. The combination of impermeant + albumin produced a biologic effect that was similar to PEG-20k alone. Capillary blood flow and plasma volume were decreased after shock with saline LVR but increased with PEG-20k, relative to saline. These data are consistent with the hypothesis that PEG-20k may act by establishing multiple osmotic gradients in the microcirculation to drive cell-to-capillary water transfer during hypovolemic shock.

INTRODUCTION: Endovascular technology during the past decade has introduced innovative strategies to manage vascular trauma. The purpose of this study was to evaluate the current use catheter-based endovascular damage-control techniques (CDET) in North, Central, and South America. METHODS: A survey was sent to the presidents of local societies in Latin America, members of the board, and past presidents of the Pan-American Trauma Society. The survey was sent using the Research Electronic Data Capture collection tool. RESULTS: A total of 67 surveys were sent with an 85 % response rate. Surgeons from 15 countries participated in the survey. All of the centers in North America had capabilities to perform these procedures. In none of these centers, however, were they performed by trauma and acute care surgeons. In Central and South America, 64 % of the surgeons responded that they have an interventional radiology service, and in 56 % of the cases, trauma and acute care surgeons were already performing CDET. Eight-eight percent of those surveyed thought that the addition of CDET to trauma would improve patient care; 86 % would be interested in further training in this technique if such programs were available. Finally, 68 % thought that the addition of CDET would help the field of acute care surgery and trauma financially. CONCLUSIONS: CDET is being performed already by trauma and acute care surgeons in Latin American countries. More research is necessary to evaluate the role of the trauma surgeon in the endovascular suite as well as training requirements.

OBJECTIVES: Limited transthoracic echocardiography (LTTE) has been introduced as a hemodynamic tool for trauma patients. The aim of this study was to evaluate the utility of LTTE during the evaluation of nonsurviving patients who presented to the trauma bay with traumatic cardiac arrest. METHODS: Approval by the Institutional Review Board was obtained. All nonsurviving patients with traumatic cardiac arrest who reached the trauma bay were evaluated retrospectively for 1 year. Comparisons between groups of patients in whom LTTE was performed as part of the resuscitation effort and those in whom it was not performed were conducted. RESULTS: From January 2012 to January 2013, 37 patients did not survive traumatic cardiac arrest while in the trauma bay: 14 in the LTTE group and 23 in the non-LTTE group. When comparing the LTTE and non-LTTE groups, both were similar in sex distribution (LTTE, 86% male; non-LTTE, 74% male; P = .68), age (34.8 versus 24.1 years; P= .55), Injury Severity Score (41.0 versus 38.2; P= .48), and percentage of penetrating trauma (21.6% versus 21.7%; P = .29). Compared with the non-LTTE group, the LTTE group spent significantly less time in the trauma bay (13.7 versus 37.9 minutes; P = .01), received fewer blood products (7.1% versus 31.2%; P = .789), and were less likely to undergo nontherapeutic thoracotomy in the emergency department (7.14% versus 39.1%; P < .05). The non-LTTE group had a mean of $3040.50 in hospital costs, compared with the mean for the LTTE group of $1871.60 (P = .0054). CONCLUSIONS: In this study, image-guided resuscitation with LTTE decreased the time in the trauma bay and avoided nontherapeutic thoracotomy in nonsurviving trauma patients. Limited TTE could improve the use of health care resources in patients with traumatic cardiac arrest.

INTRODUCTION: Hemorrhage is a major cause of preventable trauma deaths, and the ABC approach is widely used during the primary survey. We hypothesize that prioritizing circulation over intubation (CAB) can improve outcomes in patients with exsanguinating injuries. METHODS: A prospective observational study involving international trauma centers was conducted. Patients with systolic blood pressure below 90 who were intubated within 30 min of arrival were included. Prioritizing circulation (CAB) was defined as delaying intubation until blood products were started, and/or bleeding control was performed before securing the airway. Demographics, clinical data, and outcomes were recorded. RESULTS: The study included 278 eligible patients, with 61.5% falling within the "CAB" cohort and 38.5% in the "ABC" cohort. Demographic and disease characteristics, including age, sex, ISS, use of blood products, and other relevant factors, exhibited comparable distributions between the two cohorts. The CAB group had a higher proportion of penetrating injuries and more patients receiving intubation in the operating room. Notably, patients in the CAB group demonstrated higher GCS scores, lower SBP values before intubation but higher after intubation, and a significantly lower incidence of cardiac arrest and post-intubation hypotension. Key outcomes revealed significantly lower 24-hour mortality in the CAB group (11.1% vs. 69.2%), a lower rate of renal failure, and a higher rate of ARDS. Multivariable logistic regression models showed a 91% reduction in the odds of mortality within 24 h and an 89% reduction at 30 days for the CAB cohort compared to the ABC cohort. These findings suggest that prioritizing circulation before intubation is associated with improved outcomes in patients with exsanguinating injuries. CONCLUSION: Post-intubation hypotension is observed to be correlated with worse outcomes. The consideration of prioritizing circulation over intubation in patients with exsanguinating injuries, allowing for resuscitation, or bleeding control, appears to be associated with potential improvements in survival. Emphasizing the importance of circulation and resuscitation is crucial, and this approach might offer benefits for various bleeding-related conditions.

INTRODUCTION: Complex duodenal trauma is a rare injury with an incidence of 1-4.7% of all abdominal trauma. Historically, varied approaches have been used in the management of these complex injuries and the prevention of complications. This is a review of the current management methodology of complex duodenal injury. METHODS: A review of the medical literature to include the past and current management of duodenal trauma was performed. Google scholar (1970-2022) and PubMed (1970-2022) were searched using the keywords: complex duodenal trauma, surgical management, and duodenal complications. DISCUSSION: Complex duodenal trauma can be classified using the AAST grading scale as those encompassing grades III-V. Multiple studies and review articles characterize the difficulty in managing complex duodenal injuries. The tenets of operative management of duodenal trauma include the decision for damage control, resection of non-viable tissue, restoring gastrointestinal continuity, diversion of gastrointestinal contents, bile and pancreatic enzymes, allowing the repair to heal, and providing feeding access. The variety of both historic and current approaches attempt to address these tenets. The incidence of complications are as high as 65% with the most common complications including abscess formation, suture line dehiscence and fistula formation. The overall mortality ranges from 5 to 30%. CONCLUSIONS: Many different approaches and strategies have been proposed to repair complex duodenal injuries, all of which address important tenets of its management. The risk of complications remains high, therefore, it is vital to have a thoughtful and multidisciplinary approach when treating these injuries.

Surgeons in their daily practice are at the forefront in preventing and managing infections. However, among surgeons, appropriate measures of infection prevention and management are often disregarded. The lack of awareness of infection and prevention measures has marginalized surgeons from this battle. Together, the Global Alliance for Infections in Surgery (GAIS), the World Society of Emergency Surgery (WSES), the Surgical Infection Society (SIS), the Surgical Infection Society-Europe (SIS-E), the World Surgical Infection Society (WSIS), the American Association for the Surgery of Trauma (AAST), and the Panamerican Trauma Society (PTS) have jointly completed an international declaration, highlighting the threat posed by antimicrobial resistance globally and the need for preventing and managing infections appropriately across the surgical pathway. The authors representing these surgical societies call all surgeons around the world to participate in this global cause by pledging support for this declaration for maintaining the effectiveness of current and future antibiotics.

BACKGROUND: Patients with traumatic brain injury (TBI) are at high risk of venous thromboembolism events (VTE). We hypothesized that early chemical VTE prophylaxis initiation (≤24 hours of a stable head CT) in severe TBI would reduce VTE without increasing risk of intracranial hemorrhage expansion (ICHE). METHODS: A retrospective review of adult patients 18 years or older with isolated severe TBI (Abbreviated Injury Scale score, ≥ 3) who were admitted to 24 Level I and Level II trauma centers from January 1, 2014 to December 31 2020 was conducted. Patients were divided into those who did not receive any VTE prophylaxis (NO VTEP), who received VTE prophylaxis ≤24 hours after stable head CT (VTEP ≤24) and who received VTE prophylaxis >24 hours after stable head CT (VTEP>24). Primary outcomes were VTE and ICHE. Covariate balancing propensity score weighting was utilized to balance demographic and clinical characteristics across three groups. Weighted univariate logistic regression models were estimated for VTE and ICHE with patient group as predictor of interest. RESULTS: Of 3,936 patients, 1,784 met inclusion criteria. Incidences of VTE was significantly higher in the VTEP>24 group, with higher incidences of DVT in the group. Higher incidences of ICHE were observed in the VTEP≤24 and VTEP>24 groups. After propensity score weighting, there was a higher risk of VTE in patients in VTEP >24 compared with those in VTEP≤24 (odds ratio, 1.51; 95% confidence interval, 0.69-3.30; p = 0.307), however was not significant. Although, the No VTEP group had decreased odds of having ICHE compared with VTEP≤24 (odds ratio, 0.75; 95% confidence interval, 0.55-1.02, p = 0.070), the result was not statistically significant. CONCLUSION: In this large multi-center analysis, there were no significant differences in VTE based on timing of initiation of VTE prophylaxis. Patients who never received VTE prophylaxis had decreased odds of ICHE. Further evaluation of VTE prophylaxis in larger randomized studies will be necessary for definitive conclusions. LEVEL OF EVIDENCE: Therapeutic Care Management; Level III.

BACKGROUND: Tourniquet use for extremity hemorrhage control has seen a recent increase in civilian usage. Previous retrospective studies demonstrated that tourniquets improve outcomes for major extremity trauma (MET). No prospective study has been conducted to date. The objective of this study was to evaluate outcomes in MET patients with prehospital tourniquet use. We hypothesized that prehospital tourniquet use in MET decreases the incidence of patients arriving to the trauma center in shock. METHODS: Data were collected prospectively for adult patients with MET at 26 Level I and 3 Level II trauma centers from 2015 to 2020. Limbs with tourniquets applied in the prehospital setting were included in the tourniquet group and limbs without prehospital tourniquets were enrolled in the control group. RESULTS: A total of 1,392 injured limbs were enrolled with 1,130 tourniquets, including 962 prehospital tourniquets. The control group consisted of 262 limbs without prehospital tourniquets and 88 with tourniquets placed upon hospital arrival. Prehospital improvised tourniquets were placed in 42 patients. Tourniquets effectively controlled bleeding in 87.7% of limbs. Tourniquet and control groups were similarly matched for demographics, Injury Severity Score, and prehospital vital signs (p > 0.05). Despite higher limb injury severity, patients in the tourniquet group were less likely to arrive in shock compared with the control group (13.0% vs. 17.4%, p = 0.04). The incidence of limb complications was not significantly higher in the tourniquet group (p > 0.05). CONCLUSION: This study is the first prospective analysis of prehospital tourniquet use for civilian extremity trauma. Prehospital tourniquet application was associated with decreased incidence of arrival in shock without increasing limb complications. We found widespread tourniquet use, high effectiveness, and a low number of improvised tourniquets. This study provides further evidence that tourniquets are being widely and safely adopted to improve outcomes in civilians with MET. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

BACKGROUND: A transthoracic focused rapid echocardiographic evaluation (FREE) was developed to answer specific questions about treatment direction regarding the use of fluid versus ionotropes in trauma patients. Our objective was to evaluate the clinical utility of the information obtained by this diagnostic test. METHODS: The FREE was performed by an ultrasonographer or an intensivist and interpreted by a surgical intensivist using a full service portable echo machine (Vivid i; GE Healthcare). The clinical team ordering the examination was surveyed before and after the test was performed. RESULTS: During a 9-month study period, the FREE was performed in 53 patients admitted to our trauma critical care units. In 80% of patients, an estimated ejection fraction was obtained. Moderate and severe left ventricular dysfunction was diagnosed in 56% of patients, and right heart dysfunction was found in 25% of the patients. Inferior vena cava (IVC) diameter and IVC respiratory variation was visualized in 80% of patients. In 87% (46 of 53), the FREE was able to answer the clinical question asked by the primary team. Strikingly, in 54% of patients, the plan of care was modified as a result of the FREE examination. CONCLUSIONS: IVC diameter and IVC respiratory variation was able to be obtained in the majority of cases, giving an estimate of fluid status. Estimation of ejection fraction was useful in guiding the treatment plan regarding the requirement of fluid boluses versus ionotropic support. We conclude that the FREE can provide meaningful data in difficult to image critically ill trauma patients.

BACKGROUND: Biliary leak after severe hepatic trauma is a complex problem requiring multidisciplinary care. We report on our experience with endoscopic management of posttraumatic bile leaks and clarify the role of endoscopic retrograde cholangiopancreatography (ERCP). METHODS: A retrospective analysis was performed on all patients who sustained liver injury and underwent ERCP from September 2003 to September 2009. Patients who had associated biliary leak were identified. Patient demographics, injury characteristics, liver operations, endoscopic treatment, and success of endoscopic intervention were reviewed. Liver injury was managed in an interdisciplinary fashion, including immediate or delayed operation or angiography or both for primary or adjunctive hemostasis. ERCP with stenting and sphincterotomy was used to treat biliary fistulae. Sequelae of liver injury including biloma or other perihepatic fluid collection were also managed by computed tomography scan-guided or ultrasound-guided drainage. RESULTS: A total of 26 patients underwent ERCP for the management of biliary fistula as a result of severe hepatic trauma. There were 14 (54%) blunt injuries. In every patient (100%), ERCP with stenting and sphincterotomy was successful in controlling bile leak. All patients eventually had removal of stents and drains, with resolution of leak. Two patients had concomitant treatment of associated pancreatic ductal injury. CONCLUSION: ERCP is useful as both a diagnostic and therapeutic tool for the safe treatment of biliary ductal injuries after severe liver trauma and should be part of a multidisciplinary treatment algorithm.

BACKGROUND: Limited transthoracic echocardiogram (LTTE) represents an attractive alternative to formal transthoracic echocardiogram (TTE), because it does not require an echocardiogram machine. Our hypothesis is that trauma attendings can learn LTTE effectively with minimal training. METHODS: Seven attendings at a Level I trauma center received didactic and hands-on training in LTTE and performed this test on hypotensive patients to evaluate for contractility, fluid status, and pericardial effusion. Therapy to improve perfusion (administration of fluids, ionotropes, or vasopressors) was guided by LTTE findings. Perfusion status was determined by serum lactate level before and 6 hours after LTTE. Findings were compared with cardiology-performed TTE. RESULTS: Range of postresidency training was 1 year to 29 years. LTTE teaching entailed 70 minutes of didactics and 25 minutes of hands-on. In all, 52 LTTEs were performed; two patients were excluded due to blunt trauma arrest. Age ranged from 22 years to 89 years with an average of 55 years. Admission diagnosis was blunt trauma (n = 34), penetrating trauma (n = 3), and intra-abdominal sepsis (n = 13). Average time for LTTE was 4 minutes 38 seconds. Cardiology-performed TTE was obtained in all patients, and correlation with LTTE was 100%. A total of 37 patients received intravenous fluid, 9 received vasopressors, and 4 received ionotropes as guided by LTTE findings, with lactate reduction in all patients (p < 0.00001). Attendings scored a mean of 88% in a written test after training. CONCLUSIONS: Trauma attendings can successfully learn LTTE with minimal training and use the technique as a resuscitation tool in the hypotensive patient.

BACKGROUND: Social media is increasingly used in surgery, facilitating the dissemination of knowledge. Social media can potentially aid networking, education, and information exchange. This study explored the impact of tweet components and tweeter characteristics during a large surgical congress to inform recommendations for optimizing social media use at future surgical conferences. METHODS: Twitter activity was monitored during the American College of Surgeons Clinical Congress 2018 using NodeXL to extract tweets containing the conference hashtag #ACSCC18 (or #ACSCC2018). Multivariable logistic regression analysis was performed to identify independent predictors of retweet activity, also testing for multicollinearity and interactions among variables. RESULTS: There were 4386 tweets that contained #ACSCC18 (or #ACSCC2018) posted from 1023 Twitter accounts. A larger group of Twitter accounts just retweeted. Other Twitter accounts with a stake in the conference neither tweeted nor retweeted. In a multivariable analysis of original tweets, the following were all independently associated with retweets, in decreasing order of effect size: mention of other tweeters, multimedia, inclusion of other hashtags, and the number of followers. In contrast with other conferences, the inclusion of a weblink (URL)-for example, link to paper or blog-was not associated with retweets. DISCUSSION: This study helps understand social media impact at surgical conferences. Engage by tweeting and retweeting. Mention other tweeters, add multimedia, include congress hashtags and topic-specific hashtags, and build your followers. Although not associated with retweet activity in this study, the inclusion of URLs can still contribute in substantiating the disseminated content based on findings at other conferences.

ABSTRACT: Trauma-induced coagulopathy is associated with very high mortality, and hemorrhage remains the leading preventable cause of death after injury. Directed methods to combat coagulopathy and attain hemostasis are needed. The available literature regarding viscoelastic testing, including thrombelastography (TEG) and rotational thromboelastometry (ROTEM), was reviewed to provide clinically relevant guidance for emergency resuscitation. These tests predict massive transfusion and developing coagulopathy earlier than conventional coagulation testing, within 15 min using rapid testing. They can guide resuscitation after trauma, as well. TEG and ROTEM direct early transfusion of fresh frozen plasma when clinical gestalt has not activated a massive transfusion protocol. Reaction time and clotting time via these tests can also detect clinically significant levels of direct oral anticoagulants. Slowed clot kinetics suggest the need for transfusion of fibrinogen via concentrates or cryoprecipitate. Lowered clot strength can be corrected with platelets and fibrinogen. Finally, viscoelastic tests identify fibrinolysis, a finding associated with significantly increased mortality yet one that no conventional coagulation test can reliably detect. Using these parameters, guided resuscitation begins within minutes of a patient's arrival. A growing body of evidence suggests this approach may improve survival while reducing volumes of blood products transfused.

ABSTRACT: In recent years there has been a tremendous increase in hemorrhage control by endovascular methods. Traumatic and non-traumatic hemorrhage is being more frequently managed with endografts, embolization agents, and minimal invasive methods. These methods initially were used in hemodynamically stable patients only, whereas now these are being implemented in acute settings and hemodynamically unstable patients. The strategy of using endovascular and combined open-endo methods approach for hemodynamic instability in trauma and non-trauma patients has been named EVTM- EndoVascular resuscitation and Trauma Management. The EVTM concept will be presented in this article, describing how it is developed and used, as well as its limitations and future aspects.
