Splanchnic Hypoperfusion

Splanchnic hypoperfusion as reflected by gastric intramucosal acidosis has been recognized as an important determinant of outcome in shock. A comprehensive splanchnic hypoperfusion-ischemia reperfusion (IRP) protocol was evaluated against conventional shock management protocols in critical trauma patients. The study was a prospective randomized trial comparing three therapeutic approaches to hypoperfusion after severe trauma in 151 trauma patients admitted to the intensive care unit. Group 1 patients received hemodynamic support based on conventional indicators of hypoperfusion. In group 2, resuscitation was further guided by gastric tonometry-derived estimates of splanchnic hypoperfusion and included more invasive hemodynamic monitoring and additional administration of colloid or crystalloid solutions, or inotropic support. Group 3 patients additionally received therapies specifically aimed at optimizing splanchnic perfusion and minimizing oxidant-mediated damage from reperfusion. The three groups were similar based on age, Injury Severity Score, and Acute Physiology and Chronic Health Evaluation II Scores. There were no statistically significant differences in mortality rates, organ dysfunction, ventilator days, or length of stay between any of the interventions. Techniques of optimization of splanchnic perfusion and minimization of oxidant-mediated reperfusion injury evaluated in this study were not advantageous relative to standard resuscitation measures guided by conventional or tonometric measures of hypoperfusion in the therapy of occult and clinical shock in trauma patients.

Achieving adequate perfusion is a key goal of treatment in severe trauma; however, tissue perfusion has classically been measured by indirect means. Direct visualization of capillary flow has been applied in sepsis, but application of this technology to the trauma population has been limited. The purpose of this investigation was to compare the efficacy of standard indirect measures of perfusion to direct imaging of the sublingual microcirculatory flow during trauma resuscitation. Patients with injury severity scores >15 were serially examined using a handheld sidestream dark-field video microscope. In addition, measurements were also made from healthy volunteers. The De Backer score, a morphometric capillary density score, and total vessel density (TVD) as cumulative vessel area within the image, were calculated using Automated Vascular Analysis (AVA3.0) software. These indices were compared against clinical and laboratory parameters of organ function and systemic metabolic status as well as mortality. Twenty severely injured patients had lower TVD (X = 14.6 ± 0.22 vs 17.66 ± 0.51) and De Backer scores (X = 9.62 ± 0.16 vs 11.55 ± 0.37) compared with healthy controls. These scores best correlated with serum lactate (TVD R2 = 0.525, De Backer R2 = 0.576, P < 0.05). Mean arterial pressure, heart rate, oxygen saturation, pH, bicarbonate, base deficit, hematocrit, and coagulation parameters correlated poorly with both TVD and De Backer score. Direct measurement of sublingual microvascular perfusion is technically feasible in trauma patients, and seems to provide real-time assessment of micro-circulatory perfusion. This study suggests that in severe trauma, many indirect measurements of perfusion do not correlate with microvascular perfusion. However, visualized perfusion deficiencies do reflect a shift toward anaerobic metabolism.

Abstract Purpose The number of severely injured patients exceeding the age of 60 has shown a steep increase within the last decades. These patients present with numerous co-morbidities, polypharmacy, and increased frailty requiring an adjusted treatment approach. In this study, we establish an overview of changes we observed in demographics of older severe trauma patients from 2002 to 2017. Methods A descriptive analysis of the data from the TraumaRegister DGU® (TR-DGU) was performed. Patients admitted to a level one trauma center in Germany, Austria and Switzerland between 2002 and 2017, aged 60 years or older and with an injury severity score (ISS) over 15 were included. Patients were stratified into subgroups based on the admission: 2002–2005 (1), 2006–2009 (2), 2010–2013 (3) and 2014–2017 (4). Trauma and patient characteristics, diagnostics, treatment and outcome were compared. Results In total 27,049 patients with an average age of 73.9 years met the inclusion criteria. The majority were males (64%), and the mean ISS was 27.4. The proportion of patients 60 years or older [(23% (1) to 40% (4)] rose considerably over time. Trauma mechanisms changed over time and more specifically low falls (< 3 m) rose from 17.6% (1) to 40.1% (4). Altered injury patterns were also identified. Length-of-stay decreased from 28.9 (1) to 19.5 days (4) and the length-of-stay on ICU decreased from 17.1 (1) to 12.7 days (4). Mortality decreased from 40.5% (1) to 31.8% (4). Conclusion Length of stay and mortality decreased despite an increase in patient age. We ascribe this observation mainly to increased use of diagnostic tools, improved treatment algorithms, and the implementation of specialized trauma centers for older patients allowing interdisciplinary care.

Objective. Pro-protein convertase subtilisin/kexin type 9 (PCSK9) is a circulating protein that impairs LDL clearance by promoting the LDL receptor (LDLR) degradation. Plasma lipid parameters (LDL-C and HDL-C) are related to severity of illness and survival in intensive care patients. Here, we aimed to determine whether circulating PCSK9 concentrations were correlated to the severity of illness in patients with multiple trauma. Methods/Results. Plasma PCSK9 were measured, at day 0 and 8 after admission, by ELISA in 111 patients hospitalized in ICU for severe trauma. Patients were included in the HIPOLYTE study and were randomly assigned to hydrocortisone therapy or placebo. Plasma PCSK9 levels were significantly increased by 161% at day 8 compared to day 0 (481 ± 227 vs 231 ± 117 ng/ml, P=0.0001). Hydrocortisone therapy did not alter PCSK9 concentrations at day 8 compared to placebo (451 ± 216 vs 511 ± 239ng/ml, P=0.33). In the whole population of the study, PCSK9 was positively associated with LDL-C (Pearson coefficient : 0.26, p=0.007) at day 0, but not with markers of severity illness. At day 8, an inverse correlation was found between PCSK9 and HDL-C (β =-653 ; P=0.004). Interestingly, PCSK9 concentrations at day 8 were related to markers of severity illness as injury severity score (β =6.17 ; P=0.0007), length of stay in ICU (β =6.14 ; P=0.0001), duration of both mechanical ventilation (β =8.26 ; P=0.0001) and cathecolamines infusion (β =18.57; P=0.015). Conclusion. PCSK9 appears as a late biomarker of severity illness in patients hospitalized for multiple trauma in ICU. These results open new perspectives for a role of PCSK9 in critical illness.

The purpose of this study was to determine the incidence of wound dehiscence after repeat trauma laparotomy. We performed a retrospective analysis of adult trauma patients who underwent laparotomy at an urban level 1 trauma center during the past 5 years. Patients were divided into single (SL) and multiple laparotomy (ML) groups. Demographic, clinical, and outcome data were collected. Data were analyzed using χ2, t testing, and ANOVA. Overall dehiscence rate was 0.7 per cent. Multiple laparotomy patients had damage control, staged management of their injuries, or abdominal compartment syndrome as the reason for reexploration. SL and ML patients had similar age and sex. ML patients had a higher rate of intra-abdominal abscess than SL patients (13.7% vs 1.2% P < 0.0001), but intra-abdominal abscess did not predict wound dehiscence in the ML group ( P = 0.24). This was true in spite of the fact that ML patients had a significantly higher Injury Severity Score (ISS) than SL patients (21.68 vs 14.35, P < 0.0001). Interestingly, wound infection did not predict dehiscence. Patients undergoing repeat laparotomy after trauma are at increased risk for wound dehiscence. This risk appears to be associated with intraabdominal abscess and ISS, but not wound infection. Surgeons should leave the skin open in the setting of repeat trauma laparotomy, which will allow serial assessment of the integrity of the fascial closure.

Life Sustaining Treatment

Introduction: Differences in health care between racial and ethnic groups exist. The literature suggests that African Americans and Hispanics prefer more aggressive treatment at the end of life. The aim of this study is to assess racial and ethnic differences in limiting life-sustaining treatment (LLST) after trauma. Study Design: We performed a 2-year (2013-2014) retrospective analysis of Trauma Quality Improvement Program database. Patients with age ≥16 and Injury Severity Score (ISS) ≥ 16 were included. Outcome measures were the incidence and the predictors of LLST. Multivariable logistic regression was performed to control for confounding variables. Results: A total of 97 024 patients were identified. Mean age was 49 (21) years, 68% were male, 68% were white, and 14% were Hispanic. The overall incidence of LLST was 7.2%. Based on race, LLST was selected as consistent with goals of care more often in white when compared to African American individuals who experience serious traumatic injury (8.0% vs 4.5%; P < .001). Based on ethnicity, LLST was more often selected in non-Hispanics (7.5% vs 5.2%, P < .001) when compared to Hispanics. On regression analysis, the independent predictors of LLST were white race (odds ratio [OR]: 2.7 [1.6–4.4], P = .02), non-Hispanic ethnicity (OR: 1.9 [1.4-4.6]; P = .03), severe head injury (OR: 1.7 [1.1-3.2]; P = .04), and ISS (OR: 3.1 [2.4-5.1]; P < .01). Conclusions: Differences exist in selecting LLST between different racial and ethnic groups in severe trauma. African Americans and Hispanics are less likely to select LLST when compared to whites and non-Hispanics. Further studies are required to analyze the factors associated with selecting LLST in African Americans and Hispanics.

Abstract Objective: To evaluate the association between diastolic blood pressure and massive transfusion in severe trauma. Methods: The retrospective study was conducted at a tertiary emergency medical centre in Gwangju , Republic of Korea, and comprised data of severe trauma patients with injury severity score >15 presenting between January 2016 and December 2017. Multivariate logistic regression analysis was performed to evaluate the association between diastolic blood pressure and massive transfusion. Receiver operating characteristic curve analysis was performed to estimate the prognostic performance of diastolic blood pressure. Data was analysed using SPSS 18. Results: Of the 827 patients, 64(7.7%) underwent massive transfusion. After adjusting the confounders, diastolic blood pressure was found to be an independent factor in predicting massive transfusion (odds ratio: 0.965; 95% confidence interval: 0.956–0.975). Conclusion: Initially low diastolic blood pressure was found to be an independent predictor for massive transfusion in severe trauma cases. Key Words: Trauma, Diastolic blood pressure, Massive transfusion.

Background. Dysregulation of microRNAs may contribute to the progression of trauma-induced coagulopathy (TIC). We aimed to explore the biological function that miRNA-24-3p (miR-24) might have in coagulation factor deficiency after major trauma and TIC. Methods. 15 healthy volunteers and 36 severe trauma patients (Injury Severity Score ≥ 16 were enrolled. TIC was determined as the initial international normalized ratio >1.5. The miR-24 expression and concentrations of factor X (FX) and factor XII in plasma were measured. In vitro study was conducted on L02 cell line. Results. The plasma miR-24 expression was significantly elevated by 3.17-fold (P=0.043) in major trauma patients and reduced after 3 days (P<0.01). The expression level was significantly higher in TIC than in non-TIC patients (P=0.040). Multivariate analysis showed that the higher miR-24 expression was associated with TIC. The plasma concentration of FX in TIC patients was significantly lower than in the non-TIC ones (P=0.030) and controls (P<0.01). A negative correlation was observed between miR-24 and FX. miR-24 transduction significantly reduced the FX level in the supernatant of L02 cells (P=0.030). Conclusions. miR-24 was overexpressed in major trauma and TIC patients. The negative correlation of miR-24 with FX suggested the possibility that miR-24 might inhibit the synthesis of FX during TIC.

Abstract Backgrounds The COVID-19 pandemic drastically strained the health systems worldwide, obligating the reassessment of how healthcare is delivered. In Lombardia, Italy, a Regional Emergency Committee (REC) was established and the regional health system reorganized, with only three hospitals designated as hubs for trauma care. The aim of this study was to evaluate the effects of this reorganization of regional care, comparing the distribution of patients before and during the COVID-19 outbreak and to describe changes in the epidemiology of severe trauma among the two periods. Methods A cohort study was conducted using retrospectively collected data from the Regional Trauma Registry of Lombardia (LTR). We compared the data of trauma patients admitted to three hub hospitals before the COVID-19 outbreak (September 1 to November 19, 2019) with those recorded during the pandemic (February 21 to May 10, 2020) in the same hospitals. Demographic data, level of pre-hospital care (Advanced Life Support-ALS, Basic Life Support-BLS), type of transportation, mechanism of injury (MOI), abbreviated injury score (AIS, 1998 version), injury severity score (ISS), revised trauma score (RTS), and ICU admission and survival outcome of all the patients admitted to the three trauma centers designed as hubs, were reviewed. Screening for COVID-19 was performed with nasopharyngeal swabs, chest ultrasound, and/or computed tomography. Results During the COVID-19 pandemic, trauma patients admitted to the hubs increased (46.4% vs 28.3%, p < 0.001) with an increase in pre-hospital time (71.8 vs 61.3 min, p < 0.01), while observed in hospital mortality was unaffected. TRISS, ISS, AIS, and ICU admission were similar in both periods. During the COVID-19 outbreak, we observed substantial changes in MOI of severe trauma patients admitted to three hubs, with increases of unintentional (31.9% vs 18.5%, p < 0.05) and intentional falls (8.4% vs 1.2%, p < 0.05), whereas the pandemic restrictions reduced road- related injuries (35.6% vs 60%, p < 0.05). Deaths on scene were significantly increased (17.7% vs 6.8%, p < 0.001). Conclusions The COVID-19 outbreak affected the epidemiology of severe trauma patients. An increase in trauma patient admissions to a few designated facilities with high level of care obtained satisfactory results, while COVID-19 patients overwhelmed resources of most other hospitals.

Background Rapid identification of trauma severity is essential for the timely triage of multiple trauma patients. Tools such as the modified early warning score (MEWS) are used for determining injury severity. Although the conventional MEWS is a good predictor of mortality, its performance assessing injury severity is moderate. This study hypothesized that adding an injury site severity-related score (e.g., abdomen score) may enhance the capability of the MEWS for identifying severe trauma. Method To validate the hypothesis, we propose an improved modified early warning score called MEWS-A, which incorporates an injury site-specific severity-related abdomen score to MEWS. The utility of MEWS and MEWS-A were retrospectively evaluated and compared for identifying trauma severity in adult multiple trauma patients admitted to the emergency department. Results We included 1,230 eligible multiple trauma patients and divided them into minor and severe trauma groups based on the injury severity score. Results of logistic regression and receiver operating characteristic (ROC) curve analyses showed that the MEWS-A had a higher area under the ROC curve (AUC: 0.81 95% CI [0.78–0.83]) than did the MEWS (AUC: 0.77 95% CI [0.74–0.79]), indicating that the MEWS-A is superior to the MEWS in identifying severe trauma. The optimal MEWS-A cut-off score is 4, with a specificity of 0.93 and a sensitivity of 0.54. MEWS-A ≥ 4 can be used as a protocol for decision-making in the emergency department. Conclusions Our study suggests that while the conventional MEWS is sufficient for predicting mortality risk, adding an injury site-specific score (e.g., abdomen score) can enhance its performance in determining injury severity in multiple trauma patients.
