RESUMO
PURPOSE: To determine the effectiveness of vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) in patients undergoing open abdomen management (OAM). METHODS: Data from cases with OAM for at least five days who were admitted to our institution between January 2011 and December 2020 were included. We compared the patient's age, sex, medical history, indication for initial surgery, APACHE II scores, indication for OAM, operative time, intraoperative blood loss, intraoperative transfusion, success of primary fascial closure (rectus fascial closure and bilateral anterior rectus abdominis sheath turnover flap method), success of planned ventral hernia, duration of OAM, and in-hospital mortality between patients undergoing VAWCM (VAWCM cases, n = 27) and vacuum-assisted wound closure (VAWC) alone (VAWC cases, n = 25). RESULTS: VAWCM cases had a significantly higher success rate of primary fascial closure (70% vs. 36%, p = 0.030) and lower in-hospital mortality (26% vs. 72%, p = 0.002) than VAWC cases. A multivariate logistic regression analysis showed that VAWCM was an independent factor influencing in-hospital mortality (odds ratio, 0.14; 95% confidence interval: 0.04-0.53; p = 0.004). CONCLUSION: VAWCM is associated with an increased rate of successful primary fascial closure and may reduce in-hospital mortality.
RESUMO
INTRODUCTION: Disasters and accidents have occurred with increasing frequency in recent years. Primary disasters have the potential to result in mass casualty events involving crush syndrome (CS) and other serious injuries. Prehospital providers and emergency clinicians stand on the front lines of these patients' evaluation and treatment. However, the bulk of our current knowledge, derived from historical data, has remained unchanged for over ten years. In addition, no evidence-based treatment has been established to date. OBJECTIVE: This narrative review aims to provide a focused overview of, and update on, CS for both prehospital providers and emergency clinicians. DISCUSSION: CS is a severe systemic manifestation of trauma and ischemia involving soft tissue, principally skeletal muscle, due to prolonged crushing of tissues. Among earthquake survivors, the reported incidence of CS is 2-15%, and mortality is reported to be up to 48%. Patients with CS can develop cardiac failure, kidney dysfunction, shock, systemic inflammation, and sepsis. In addition, late presentations include life-threatening systemic effects such as hypovolemic shock, hyperkalemia, metabolic acidosis, and disseminated intravascular coagulation. Immediately beginning treatment is the single most important factor in reducing the mortality of disaster-situation CS. In order to reduce complications from CS, early, aggressive resuscitation is recommended in prehospital settings, ideally even before extrication. However, in large-scale natural disasters, it is difficult to diagnose CS, and to reach and start treatments such as continuous administration of massive amounts of fluid, diuresis, and hemodialysis, on time. This may lead to delayed diagnosis of, and high on-site mortality from, CS. To overcome these challenges, new diagnostic and therapeutic modalities in the CS animal model have recently been advanced. CONCLUSIONS: Patient outcomes can be optimized by ensuring that prehospital providers and emergency clinicians maintain a comprehensive understanding of CS. The field is poised to undergo significant advances in coming years, given recent developments in what is considered possible both technologically and surgically; this only serves to further emphasize the importance of the field, and the need for ongoing research.

AIM: This study aimed to measure the influence of wearing face masks on individuals' physical status in a hot and humid environment. METHODS: Each participant experienced different physical situations: (i) not wearing a mask (control), (ii) wearing a surgical mask, (iii) wearing a sport mask. An ingestible capsule thermometer was used to measure internal core body temperature during different exercises (standing, walking, and running, each for 20 min) in an artificial weather room with the internal wet-bulb globe temperature set at 28°C. The change in the participants' physical status and urinary liver fatty acid-binding protein (L-FABP) were measured. RESULTS: Six healthy male volunteers were enrolled in the study. In each participant, significant changes were observed in the heart rate and internal core temperatures after increased exercise intensity; however, no significant differences were observed between these parameters and urinary L-FABP among the three intervention groups. CONCLUSION: Mask wearing is not a risk factor for heatstroke during increased exercise intensity.
RESUMO
AIM: Alcohol-related problems, including trauma, are a great burden on global health. Alcohol metabolism in the Japanese population is genetically inferior to other races. This study aimed to evaluate the effects of alcohol use among a Japanese severe blunt trauma cohort. METHODS: This retrospective observational study analyzed the data of trauma patients registered in the Japan Trauma Data Bank between 2004 and 2019. The primary outcome of this study was in-hospital mortality. The lengths of hospital and intensive care unit stay were the secondary outcomes. Propensity score matching was used to adjust the anatomical severity and patient background to reduce the potential alcohol use bias. RESULTS: We analyzed 46,361 patients categorized into nondrinking (n = 37,818) and drinking (n = 8,543) groups. After a 1:1 propensity score matching (n = 8,428, respectively), despite the Glasgow Coma Scale and Revised Trauma Score scores being significantly lower in the drinking group (14 vs. 13 and 7.84 vs. 7.55, P < 0.001, respectively) and intensive care unit length of stay being significantly longer in the drinking group (6 vs. 7 days, P = 0.002), in-hospital mortality was significantly lower in the alcohol group (11.8% vs. 9.0%, P < 0.001) and there were no differences in the duration of hospital stay (19 vs. 19 days, P = 0.848). CONCLUSION: Despite increasing physiological severity on admission, after adjusting for anatomical severity, alcohol consumption could be beneficial in severe blunt trauma patients as regards in-hospital mortality.
RESUMO
PURPOSE: This study investigated the advantages of performing urgent resuscitative surgery (URS) in the emergency department (ED); namely, our URS policy, to avoid a delay in hemorrhage control for patients with severe torso trauma and unstable vital signs. METHODS: We divided 264 eligible cases into a URS group (n = 97) and a non-URS group (n = 167) to compare, retrospectively, the observed survival rate with the predicted survival using the Trauma and Injury Severity Score (TRISS). RESULTS: While the revised trauma score and the injury severity score were significantly lower in the URS group than in the non-URS group, the observed survival rate was significantly higher than the predicted rate in the URS (48.5 vs. 40.2%; p = 0.038). URS group patients with a systolic blood pressure (SBP) <90 mmHg and a Glasgow coma scale (GCS) score of ≥9 had significantly higher observed survival rates than predicted survival rates (0.433 vs. 0.309, p = 0.008), (0.795 vs. 0.681, p = 0.004). The implementation of damage control surgery (DCS) was found to be a significant predictor of survival (OR 5.23, 95% CI 0.113-0.526, p < 0.010). CONCLUSION: The best indications for the URS policy are an SBP <90 mmHg, a GCS ≥9 on ED arrival, and/or the need for DCS. By implementing our URS policy, satisfactory survival of patients requiring immediate hemostatic surgery was achieved.

PATIENT: A healthy 37-year-old man who bruised his chest with a steel frame developed ventricular fibrillation, pulseless ventricular tachycardia, and temporary torsade de pointes, and was resuscitated with emergency medical treatment. Thallium 201 scintigraphy 7 days later revealed a defect only in a small area of the apex, whereas 123 I-beta-methyl iodophenyl pentadecanoic acid scintigraphy showed defects in a larger area of the apex, ventricular septum, and inferior wall, indicating perfusion-metabolism mismatch. Follow-up dual myocardial scintigraphy on day 49 showed that the scintigraphic defects persisted only at a small area of the apex. CONCLUSION: Blunt external force appeared to have caused perfusion-metabolism mismatch and subsequent life-threatening arrhythmias in this patient.
