Severe traumatic brain injury and hypotension is a frequent and lethal combination in multiple trauma patients in mountain areas \u2013 an analysis of the prospective international Alpine Trauma Registry

BackgroundHypotension is associated with worse outcome in patients with traumatic brain injury (TBI) and maintaining a systolic blood pressure (SBP) ≥110 mmHg is recommended. The aim of this study was to assess the incidence of TBI in patients suffering multiple trauma in mountain areas; to describe associated factors, treatment and outcome compared to non-hypotensive patients with TBI and patients without TBI; and to evaluate pre-hospital variables to predict admission hypotension.MethodsData from the prospective International Alpine Trauma Registry including mountain multiple trauma patients (ISS ≥ 16) collected between 2010 and 2019 were analysed. Patients were divided into three groups: 1) TBI with hypotension, 2) TBI without hypotension and 3) no TBI. TBI was defined as Abbreviated Injury Scale (AIS) of the head/neck ≥3 and hypotension as SBP < 110 mmHg on hospital arrival.ResultsA total of 287 patients were included. Fifty (17%) had TBI and hypotension, 92 (32%) suffered TBI without hypotension and 145 (51%) patients did not have TBI. Patients in group 1 were more severely injured (mean ISS 43.1 ± 17.4 vs 33.3 ± 15.3 vs 26.2 ± 18.1 for group 1 vs 2 vs 3, respectively, p < 0.001). Mean SBP on hospital arrival was 83.1 ± 12.9 vs 132.5 ± 19.4 vs 119.4 ± 25.8 mmHg (p < 0.001) despite patients in group 1 received more fluids. Patients in group 1 had higher INR, lower haemoglobin and lower base excess (p < 0.001). More than one third of patients in group 1 and 2 were hypothermic (body temperature < 35 °C) on hospital arrival while the rate of admission hypothermia was low in patients without TBI (41% vs 35% vs 21%, for group 1 vs 2 vs 3, p = 0.029). The rate of hypothermia on hospital arrival was different between the groups (p = 0.029). Patients in group 1 had the highest mortality (24% vs 10% vs 1%, p < 0.001).ConclusionMultiple trauma in the mountains goes along with severe TBI in almost 50%. One third of patients with TBI is hypotensive on hospital arrival and this is associated with a worse outcome. No single variable or set of variables easily obtainable at scene was able to predict admission hypotension in TBI patients.

The Impact of Monitoring Depth of Anesthesia and Nociception on Postoperative Cognitive Function in Adult Multiple Trauma Patients.

Background and Objectives: Patients with traumatic injuries have often been excluded from studies that have attempted to pinpoint modifiable factors to predict the transient disturbance of the cognitive function in the postoperative settings. Anesthetists must be aware of the high risk of developing postoperative delirium and cognitive dysfunction (POCD) in patients undergoing emergency surgery. Monitoring the depth of anesthesia in order to tailor anesthetic delivery may reduce this risk. The primary aim of this study was to improve the prevention strategies for the immediate POCD by assessing anesthetic depth and nociception during emergency surgery. Material and Methods: Of 107 trauma ASA physical status II–IV patients aged over 18 years undergoing emergency noncardiac surgery, 95 patients were included in a prospective randomized study. Exclusion criteria were neurotrauma, chronic use of psychoactive substances or alcohol, impaired preoperative cognitive function, pre-existing psychopathological symptoms, or expected surgery time less than 2 h. Entropy and Surgical Pleth Index (SPI) values were constantly recorded for one group during anesthesia. POCD was assessed 24 h, 48 h, and 72 h after surgery using the Neelon and Champagne (NEECHAM) Confusion Scale. Results: Although in the intervention group, fewer patients experienced POCD episodes in comparison to the control group, the results were not statistically significant (p < 0.08). The study showed a statistically significant inverse correlation between fentanyl and the NEECHAM Confusion Scale at 24 h (r = −0.32, p = 0.0005) and 48 h (r = −0.46, p = 0.0002), sevoflurane and the NEECHAM Confusion Scale at 24 h (r = −0.38, p = 0.0014) and 48 h (r = −0.52, p = 0.0002), and noradrenaline and POCD events in the first 48 h (r = −0.46, p = 0.0013 for the first 24 h, respectively, and r = −0.46, p = 0.0002 for the next 24 h). Conclusions: Entropy and SPI monitoring during anesthesia may play an important role in diminishing the risk of developing immediate POCD after emergency surgery.

The CAST study protocol: a cluster randomized trial assessing the effect of circumferential casting versus plaster splinting on fracture redisplacement in reduced distal radius fractures in adults

BackgroundThere is no consensus concerning the optimal casting technique for displaced distal radius fractures (DRFs) following closed reduction. This study evaluates whether a splint or a circumferential cast is most optimal to prevent fracture redisplacement in adult patients with a reduced DRF. Additionally, the cost-effectiveness of both cast types will be calculated.Methods/designThis multicenter cluster randomized controlled trial will compare initial immobilization with a circumferential below-elbow cast versus a below-elbow plaster splint in reduced DRFs. Randomization will take place on hospital-level (cluster, n = 10) with a cross-over point halfway the inclusion of the needed number of patients per hospital. Inclusion criteria comprise adult patients (≥ 18 years) with a primary displaced DRF which is treated conservatively after closed reduction. Multiple trauma patients (Injury Severity Score ≥ 16), concomitant ulnar fractures (except styloid process fractures) and patients with concomitant injury on the ipsilateral arm or inability to complete study forms will be excluded. Primary study outcome is fracture redisplacement of the initial reduced DRF. Secondary outcomes are patient-reported outcomes assessed with the Disability Arm Shoulder Hand score (DASH) and Patient-Rated Wrist Evaluation score (PRWE), comfort of the cast, quality of life assessed with the EQ-5D-5L questionnaire, analgesics use, cost-effectiveness and (serious) adverse events occurence. In total, 560 patients will be included and followed for 1 year. The estimated time required for inclusion will be 18 months.DiscussionThe CAST study will provide evidence whether the type of cast immobilization is of influence on fracture redisplacement in distal radius fractures. Extensive follow-up during one year concerning radiographic, functional and patient reported outcomes will give a broad view on DRF recovery.Trial registrationRegistered in the Dutch Trial Registry on January 14th 2020.

یافته های سی تی سینه در بیماران با ترومای قفسه سینه مراجعه کننده به بیمارستان امام رضا (ع) تبریز در سال ۹۵: يك گزارش كوتاه

Introduction: Imaging technique plays an important role in management of chest trauma and chest x-ray, ultrasonography, and computed tomography (CT) scan are used to diagnose chest injuries. Chest CT scan is the Gold standard for diagnosing chest injuries. The aim of this study was to evaluate the positive findings of chest CT scan in patients referring to the emergency department of Imam Reza Hospital, Tabriz, in 2016-2017. Methods: This is a descriptive study performed on multiple trauma patients referring to Imam Reza Hospital in Tabriz from April 2016 to March 2017. The sampling method was census and all patients with multiple trauma and chest trauma who had referred to Imam Reza Hospital during the study period and had undergone a chest spiral CT were included in the study. Independent t-test was used to compare quantitative data and chi-square was used to compare qualitative data. Results: During the study period, 390 patients with chest trauma and multiple trauma had undergone chest CT. Of which, 296 were male (75.9%) and 94 (24.1%) were female. The mean age of the patients was 48.35 years. Traffic accidents were the most common cause of trauma. In nearly half of the patients there was no positive finding on chest spiral CT scan. However, there were multiple findings in 21 patients. The most common injuries were: rib fracture (11.3%), pneumothorax (12.3%), pneumomediastinum (2%), hemothorax (4.6%), and pulmonary contusion (4.9%). Conclusion: In patients with multiple trauma, the most common positive CT findings were rib fractures, followed by pneumothorax, subcutaneous emphysema and hemothorax. In cases where there is a fracture of the first three ribs or flail chest, or a fracture of the scapula and high-energy trauma, the rate of visceral damage inside the chest and abdomen is higher, and chest CT scan can diagnose hemothorax and minor pneumothorax, which are not detectable in chest x-ray.

The association of hand and wrist injuries with other injuries in multiple trauma patients. A retrospective study in a UK Major Trauma Centre

BackgroundApproximately 20,000 major trauma cases occur in England every year. However, the association with concomitant upper limb injuries is unknown. This study aims to determine the incidence, injury pattern and association of hand and wrist injuries with other body injuries and the Injury Severity Score (ISS) in multiply injured trauma patients. MethodsSingle centre retrospective study was performed at a level-one UK Major Trauma Centre (MTC). Trauma Audit and Research Network (TARN) eligible multiply injured trauma patients that were admitted to the hospital between January 2014 and December 2018 were analysed. TARN is the national trauma registry. Eligible patients were: a trauma patient of any age who was admitted for 72 h or more, or was admitted to intensive care, or died at the hospital, was transferred into the hospital for specialist care, was transferred to another hospital for specialist care or for an intensive care bed and whose isolated injuries met a set of criteria. Data extracted included: age, gender, mode of arrival, location of injuries including: hand and/or wrist and mechanism of injury. We performed a logistic regression analysis to assess the association between hand/wrist injury to ISS score of 15 points or above/below and to the presentation of other injuries. Results107 patients were analysed. Hand and wrist injuries were the second most common injury (26.2%), after thoracic injuries. Distal radial injuries were found in 5.6%, carpal/carpometacarpal in 6.5%, concurrent distal radius and carpometacarpal in 0.9%, phalangeal injuries in 4.7%, tendon injuries in 0.9% and concurrent hand and wrist injuries in 7.5% cases. There was a significant association between hand or wrist injuries and lower limb injuries (Odds Ratio (OR): 3.84; 95% confidence intervals (CI): 1.09 to 13.50; p = 0.04) and pelvic injuries (OR: 4.78; 95% CI: 1.31 to 17.44; p = 0.02). There was no statistical association between hand and wrist injuries and ISS score (OR: 0.80; 95% CI: 0.11 to 5.79; p = 0.82). ConclusionsHand and wrist injuries are prevalent in trauma patients admitted to MTCs. They should not be under-estimated but routinely screened for in multiply injured patients particularly those with a pelvic or lower limb injury.

P119 The association of hand and wrist injuries with other skeletal injuries in multiple trauma patients in a UK Major Trauma Centre

BackgroundThere are 20,000 major trauma cases in England annually yet the association with concomitant upper limb injuries is unknown. Injuries of the hand and wrist can cause serious functional impairment, decreased quality of life and confer a significant economic burden to healthcare systems. The aim of this study was to determine the incidence, injury pattern and association of hand/wrist injuries with other injuries and the ISS score in multiple trauma patients in the UK.MethodsA single centre retrospective cohort study was performed at a level one trauma centre. Trauma Association & Research Network (TARN) eligible patients during a 5-year period were included.ResultsA total of 107 patients were included in this study. Seventy patients had an ISS<15 and 37: had an ISS>15. The majority were male (70.1%) and the mean age was 45 Years. Hand and wrist injuries were the second most common injury found in 26.2% of patients.There was a significant association between hand/wrist injuries and lower limb injuries (p = 0.04) and pelvic injuries (p = 0.02). The association between hand and wrist injuries with ISS score was found to be not significant (p = 0.82).ConclusionHand and wrist injuries should be screened for in multiply injured patients with a pelvic or lower limb injury.

Comparing the Short-Term Outcome after Polytrauma and Proximal Femur Fracture in Geriatric Patients

Because of demographic change, geriatric patients are becoming a major challenge for traumatology. Multiple trauma patients and patients with proximal femoral fractures are important groups of patients in geriatric traumatology. This retrospective study compares two patient groups with different severities of injuries, and analyzes their patient characteristics and short-term outcomes, focusing on functionality upon discharge. The investigation aims to present the characterizing features of both patient groups, and to identify the potential risk factors for early functionality after trauma. The patient collective comprises two patient groups: a polytrauma group with 91 patients, and a femoral fracture group with 132 patients. Under the control of potential influencing factors, the present study showed no significant influence of belonging to either of the patient groups (multiple trauma or proximal femoral fracture) on the mobility status at discharge. Age, known dementia, pre-clinical intubation, and the lowest Hb value were identified as significant influencing factors. Despite their old age and vulnerability, the majority of geriatric patients survive accidents. Further prospective investigations concerning the maintenance or restoration of functionality after an accident are therefore desirable.

A cross-sectional study on the prevalence of electrolyte abnormalities in multiple trauma patients in Hamedan, Iran.

IntroductionEvaluation of electrolyte status and homeostasis is one of the most important components of evaluation and treatment of critically ill patients, especially those with multiple trauma. Electrolyte imbalance can be associated with a bad prognosis and the need of specialized consultancy.AimThe aim of this study was to evaluate and determine the electrolyte status of patients with multiple trauma and evaluate the relationship of electrolyte disorders with patient outcome.MethodsIn this cross‐sectional study, 370 patients who were referred to the emergency department of Besat Hospital in Hamadan, Iran with multiple trauma were studied. Demographic parameters clinical characteristics such as blood pressure, heart rate, respiratory rate, consciousness score and body temperature, paraclinical characteristics including radiographic status, ultrasound, and electrocardiography and serum levels of sodium, potassium, creatinine, hemoglobin, hematocrit, and BUN and urine analysis was performed. Data regarding the discharge from emergency department or referral to other units were also complete in a questionnaire for each patient. Statistical analyses were performed using SPSSv24.ResultsThree hundred seventy patients with multiple trauma were studied where 73% of patients were men and 27% were women. One hundred ninety‐six patients were discharged from the emergency department, and 174 patients were referred to other units of the hospital. The most common electrolyte abnormalities were hypotension (62.7%), hypernatremia (9.5%), hypokalemia (6.8%), and hypercreatinine (4.6%). The results of independent t‐test showed that heart rate and potassium level were significantly higher in patients referred to other units than in patients discharged from the emergency department and respiratory rate and hematocrit were significantly lower in patients referred to other units.ConclusionHypotension, hypernatremia, hypokalemia, hypercreatinine, and abnormal urine analysis were more frequent in patients referred to other units than in patients discharged from the emergency department. These variables can be considered in predicting patient status for referral to other units and delayed hospital discharge.

Comparison of Trauma Severity Scores (ISS, NISS, RTS, BIG Score, and TRISS) in Multiple Trauma Patients.

Trauma severity scoring systems are routinely used to monitor trauma patient outcomes. Yet, the most accurate scoring system remains an elusive target. We aim to compare trauma severity scales (ISS, NISS, RTS, TRISS, and BIG) in multitrauma patients and investigate BIG as one of the new trauma severity scoring systems. The demographic data of the patients, vital signs, injury mechanisms, body regions exposed to trauma, final diagnosis, the injury severity scales-Injury Severity Score (ISS), New Injury Severity Score (NISS), Revised Trauma Score (RTS), base deficit, international normalized ratio, and Glasgow Coma Scale (BIG), and Trauma and Injury Severity Score (TRISS)-the length of stay in hospital, and the progress of the patients were examined. A total of 426 cases were included in the study. The best performing score in determining mortality was TRISS (area under the curve [AUC]: 0.93, sensitivity 97.1% and specificity 76.7%). This was followed by the NISS, BIG, ISS, and RTS, respectively. For the prediction of intensive care unit admission, the NISS was the most successful with an AUC value of 0.81. There was a significant relationship in terms of the length of stay in all trauma scores (p < .05). The most successful score in predicting mortality in trauma patients was the TRISS, whereas the NISS was the most successful in predicting intensive care unit admission. The newly developed BIG score can be used as a strong scoring method for predicting prognosis in trauma patients.

Development and prospective validation of a novel risk score for predicting the risk of lower extremity deep vein thrombosis among multiple trauma patients

IntroductionTrauma patients have an increased risk of deep vein thrombosis (DVT). Early identification of patients with a high risk of DVT after trauma is crucial for thromboembolism prophylaxis. We aimed to develop and prospectively validate a novel risk score based on a nomogram to predict lower extremity DVT among multiple trauma patients. Materials and methodsClinical data were collected from 281 multiple trauma patients who were admitted to our trauma center within 24 h of admission from January 2016 to September 2019 to develop a novel DVT risk score. The DVT risk estimates were then calculated prospectively based on the score in a new study cohort from October 2019 to July 2020. The technique of least absolute shrinkage and selection operator (LASSO) was used to select variables for the early prediction of DVT in multiple trauma patients. The DVT risk assessment score (DRAS) was constructed by incorporating related features based on the LASSO analysis and nomogram prediction model. Further, the multiple trauma patients were divided into various risk groups according to the DRAS. The incidence of lower extremity DVT was compared between groups and the discrimination of the DRAS was assessed using the area under the curve (AUC). ResultsBased on the LASSO method, seven variables (age, injury severity score, body mass index, lower extremity fracture, D-dimer level, fibrin degradation products, and prothrombin time) were included in the DRAS. A total of 166 multiple trauma patients were enrolled in the prospective study. Increased risk of DVT after trauma was related to higher DRAS. The area under the receiver operating characteristic (ROC) curve for the DRAS was 0.890 (0.841–0.940) in the validation cohort. Moreover, the discriminatory capacity of the DRAS was superior to that of each variable independently and the TESS score (P < 0.05). ConclusionsWe developed and prospectively validated the DRAS as a reliable tool for predicting the risk of lower extremity DVT among patients with multiple trauma. This may help guide trauma surgeons in making sound decisions in the administration of DVT prophylaxis.

Practical tips for performing resuscitative endovascular balloon occlusion of the aorta

Background: Hemorrhage is the leading cause of death in trauma settings. Non-compressible torso hemorrhage, which is caused by abdominopelvic and thoracic injuries, is an important cause of subsequent organ dysfunction and poor outcomes in multiple trauma patients. The management of hemodynamically unstable patients with non-compressible torso hemorrhage has changed, and the concept of damage control resuscitation has been developed in the last decades. Currently, resuscitative endovascular balloon occlusion of the aorta (REBOA) as a method of temporary stabilization is the modern evolution of bleeding control, and it is in the middle of a paradigm shift as a treatment for non-compressible torso hemorrhage. Despite its effectiveness in patients with hemorrhagic shock, the application of REBOA remains limited because of lack of experience and troubleshooting guidelines. Objectives: The aim of study was to provide useful tips for the implementing a step-by-step procedure for REBOA in various hospital settings and capabilities. Methods: We introduced REBOA procedures using a REBOA-customized 7 Fr balloon catheter through the animation models or radiography from preparation to access, catheter management, and device removal after procedure completed. Results: We have described REBOA procedures as follows: identification of the common femoral artery, arterial access for placement of a guidewire, precautions during a sheath insertion, guidewire and balloon positioning in the aorta, occlusion zones and adjustment of balloon location, REBOA strategy for extending the occlusion time, balloon deflation and removal, sheath removal, and medical records. Conclusion: We believe that the practical tips mentioned in this article will help in performing the REBOA procedure systematically and developing an effective REBOA framework.

Early myocardial damage (EMD) and valvular insufficiency result in impaired cardiac function after multiple trauma in pigs

One third of multiple trauma patients present abnormal echocardiographic (ECHO) findings. Therefore, ECHO diagnostic after trauma is indicated in case of hemodynamic instability, shock, after chest trauma and after cardiac arrest. 20 male pigs underwent multiple trauma. Blood samples were collected 4 and 6 h after trauma and concentrations of heart-type fatty acid binding protein (HFABP) as a biomarker for EMD were measured. Myocardial damage was evaluated by scoring Hematoxylin–Eosin stained sections. At baseline, 3 and 6 h after trauma, transesophageal ECHO (TOE) was performed, invasive arterial and left ventricular blood pressure were measured to evaluate the cardiac function after multiple trauma. Systemic HFABP concentrations were elevated, furthermore heart injury score in multiple trauma animals was increased determining EMD. A significant decrease of blood pressure in combination with a consecutive rise of heart frequency was observed. Ongoing depression of mean arterial pressure and diastolic blood pressure were accompanied by changes in ECHO-parameters indicating diastolic and systolic dysfunction. Furthermore, a valvular dysfunction was detected. In this study complex myocardial and valvular impairment after multiple trauma in pigs has been observed. Therefore, detection of EMD and progressive valvular dysfunction might be crucial and therapeutically relevant.

Multivariate analysis of early surgical management factors affecting posttraumatic penoscrotal avulsion injury: a level I trauma center study

BackgroundTo conduct an accurate evaluation of patients presenting with posttraumatic penoscrotal injuries, and to formulate a treatment algorithm based on this assessment.MethodsWe conducted a retrospective chart review study. Patients with penoscrotal defects admitted to our level I trauma center from 2017 to 2019 were evaluated. The Braden scale score was used for wound evaluation and the Korean patient classification system (KPCS) was used for assessment of severity. Univariate and multivariate analyses were performed for potential risk factors associated with early surgical management.ResultsIn total, there were 58 male patients, and the average Braden scale score was 12.08 ± 2.54, with the scrotum (36.20%), and the penile shaft (32.76%) being popular sites for injuries. The wounds requiring surgical treatment were 20.68% (n = 12), with local flaps (33.33%) being most commonly used. The significant predictors of advanced wounds which required surgical treatment were old age (p = 0.026, odds ratio [OR] 8.238), orthopedic combined injuries (p = 0.044, OR 1.088), intubation (p = 0.018, OR 9.625), restraint (p = 0.036, OR 0.157) and blood transfusion (p < 0.001, OR 2.462).ConclusionIn multiple trauma patients, penoscrotal defects caused by high-speed trauma are an important matter of concern. Specifically, patients with combined skeletal injuries or requiring respiratory care were prone to advanced wounds. We proposed a five-category algorithm to manage such patients, which included severity of the patient’s condition, respiration, hemodynamic status, comorbidity, and immobilization. Additionally, inter-departmental cooperation and active intervention by plastic surgeons is needed for the comprehensive treatment of such injuries.Trial registration This study was performed in line with the principles of the Declaration of Helsinki. The study and all its protocols were approved by the institutional review board of Ajou Medical Center (approval no. AJIRB-MED-MDB-17-254). The need for informed consent was waived by the institutional review board of our hospital due to the retrospective design of the study.

Predictive value of prognostic factors at multiple trauma patients in intensive care admission

Purpose We aimed to evaluate the relationship between trauma patients' mortality and neutrophil/lymphocyte ratio (NLR) at intensive care units admission. Methods We examined 107 ICU trauma patients. Patients were divided into two groups as those who survived (Grup I) and deceased (Grup II). Patients' age, NLR, mean platelet volume (MPV), lactate value, length of stay in the intensive care unit, acute physiology and chronic health evaluation 2 (APACHE II) scores were examined. The effects of these factors on mortality were examined. Results 83 (77.58 %) patients were male, 24 (22.42 %) patients were female. The patients' mean age was 46.89 ± 19.06 years. The mean value of the lactate level was 3.25 ± 2.92, the mean value of MPV was 10.34 ± 1.02, the average value of NLR was 8.23 ± 8.11, the average score of APACHE II was 22.8 ± 8.75, and the average length of stay in the ICU was 11.33 ± 22.98 days. The relationship with mortality was evaluated between the groups, there was a statistically significant difference in APACHE II scores. There was no statistically significant difference between other variables. Conclusions NRL, MPV, lactate levels were not suitable for the evaluation of trauma patients as an early prognostic factor like APACHE II during admission to ICU (Tab. 2, Fig. 1, Ref. 23).

The accuracy of various types of urinalysis in terms of predicting intra-abdominal injury in emergency trauma patients: A diagnostic accuracy study

Background and Objectives: Given the importance and prevalence of trauma patients in the emergency department and the questioning of urinalysis value in predicting intra-abdominal injury, this study was conducted to examine the accuracy of various types of this test. Methods: This diagnostic accuracy study was conducted on adult patients with abdominal trauma. Data gathering were performed retrospectively until sample size completion using a preprepared checklist. Required data, including demographic characteristics, diseases confounding urinalysis, trauma mechanism, important associated injuries, vital signs, etc., were recorded. Accuracy of urinalysis (including macroscopic, microscopic and dipstick) results was compared with findings of patients' enhanced computed tomography (CT) scan findings that was considered as the gold standard, reported by a radiologist. Results: Totally, 152 multiple trauma patients with the mean age of 37.9 ± 17.7 years were enrolled (90.8% males), of whom 66 (43.42%) patients had hematuria and the CT scan was abnormal in 30 (19.73%) cases. There was a significant correlation between gross hematuria and abnormal CT scan (P 0.05). Based on the findings, the highest sensitivity was for dipstick and microscopic equally and highest specificity, positive predictive value, negative predictive value, positive and negative likelihood ratios, NLR and accuracy were for the gross test. Conclusions: Microscopic hematuria and dipstick had no significant correlation with abnormal CT scan findings and cannot predict the intra-abdominal injuries in multiple trauma patients. But, macroscopic hematuria could be valuable in this regard.

A comparison between modified early warning score, worthing physiological scoring system, national early warning score, and rapid emergency medicine score in predicting inhospital mortality in multiple trauma patients

A comparison between modified early warning score, worthing physiological scoring system, national early warning score, and rapid emergency medicine score in predicting inhospital mortality in multiple trauma patients

Utility of ETCO2 to predict hemorrhagic shock in multiple trauma patients.

For identifying hemorrhagic shock in trauma patients, some objective data are needed. The use of base excess (BE) and lactate values have been originated. In this study, it was aimed to determine the usability of end tidal carbon dioxide (ETCO₂) in patients with multiple trauma for recognizing hemorrhagic shock. Patients who were admitted to the emergency department between June 2019 and February 2020 with highenergy multiple trauma were included in the study. ETCO₂ and BE values were measured. Correlation coefficients were calculated to determine correlations between ETCO₂ and BE levels. One hundred and twenty-two patients were included in the study. Eighty-nine (73%) were men and 33 (27%) were women, and the mean age of the study population was 38.70 ± 19.18. The mortality rate was 14.8% in the study population. The correlation between ETCO₂ and BE values was significant (r: 0.27) and in the same range in the Bland-Altmann analysis. ETCO₂ levels above 35 were specific for stage 1 hemorrhagic shock. ETCO2 levels below 30 were sensitive for stage 2 and 3 hemorrhagic shocks and when the levels were measured below 22 it was found specific for stage 4 shock. The specificity increased to 99% at levels below 18. The sensitivity for ETCO₂ values below 22 for predicting mortality was 33.33%, the specificity was 89.42%, the positive predictive value was 35.29% and the negative predictive value was 88.57%. The sensitivity for BE values below -10 for predicting mortality was 50%, the specificity was 93.27%, the positive predictive value was 56.25% and the negative predictive value was 91.51%.

Diagnostic value of intravenous oxygen saturation compared with arterial and venous base excess to predict hemorrhagic shock in multiple trauma patients.

Introduction:In this study, with the help of peripheral vein sampling, Spvo2, and peripheral artery and vein sampling, we examined base excess (BE) in trauma patients and determined its diagnostic value for hemorrhagic shock.Methods:In this cross-sectional study, from 64 patients with abdominal, pelvic and chest Blunt trauma who have a score of 2 or higher trauma during treatment, blood samples were taken from peripheral vein to measure oxygen saturation and peripheral vein and artery for BE measurements and were compared in order to assess their diagnostic value in predicting the occurrence of hemorrhagic shock.Results:Out of 60 examined patients, 43 (71.67%) patients were diagnosed with hemorrhagic shock. The correlation for the percentage of oxygen saturation of the peripheral blood and the rate of arterial and venous BE for these r2 patients were 17.0 and 09.0, respectively, with a P value greater than 0.005. In the case of the percentage of oxygen saturation of the peripheral blood, the sensitivity and specificity were 93.03 and 11.76%, respectively. The positive and negative likelihood ratios were 1.05 and 0.59, respectively. The positive and negative predictive values were 72.73 and 40%, respectively.Conclusion:In general, the results of this study showed that arterial and venous excess base levels had a proper correlation, specificity and sensitivity for diagnosing and predicting hemorrhagic shock, while the percentage of oxygen saturation of peripheral blood and BE arterial and venous levels had not proper correlation to detect and predict hemorrhagic shock.

Surgical treatment in hepatic trauma: factors associated with hospitalization time.

the aim of this study was to identify associated factors with the increased length of hospital stay for patients undergoing surgical treatment for liver trauma, and predictors of mortality as well as the epidemiology of this trauma. retrospective study of 191 patients admitted to the Cajuru University Hospital, a reference in the treatment of multiple trauma patients, between 2010 and 2017, with epidemiological, clinicopathological and therapeutic variables analyzed using the STATA version 15.0 program. most of the included patients were men with a mean age of 29 years. Firearm injury represents the most common trauma mechanism. The right hepatic lobe was injured in 51.2% of the cases, and hepatorraphy was the most commonly used surgical correction. The length of hospital stay was an average of 11 (0-78) days and the length of stay in the intensive care unit was 5 (0-52) days. Predictors for longer hospital stay were the mechanisms of trauma, hemodynamic instability at admission, number of associated injuries, degree of liver damage and affected lobe, used surgical technique, presence of complications, need for reoperation and other surgical procedures. Mortality rate was 22.7%. the study corroborated the epidemiology reported by the literature. Greater severity of liver trauma and associated injuries characterize patients undergoing surgical treatment, who have increased hospital stay due to the penetrating trauma, hemodynamic instability, hepatic packaging, complications and reoperations.

Predictive value of the glasgow coma scale, age, and arterial blood pressure and the new trauma score indicators to determine the hospital mortality of multiple trauma patients

Background: Authoritative trauma scoring systems can quickly assess the damage and show its severity plus prognosis. The purpose of this study was to investigate the predictive value of the new Glasgow Coma Scale, age, and systolic blood pressure (GAP) and the new trauma score (NTS) indicators to determine the mortality of trauma patients in hospitals in Sirjan in 2019. Materials and Methods: In a descriptive-analytical study, 2570 patients with multitrauma caused by traffic accidents transferred by the prehospital emergency were enrolled in the study. Demographic variables of patients as well as GAP and NTSs were collected and calculated, with the outcome of patients followed up and recorded during hospitalization. The predictive value of these scores was determined in clarifying the outcome of patients using SPSS software. Results: Of the total number of patients studied, 14 (0.5%) patients died during hospitalization. The mean GAP and NTS scores in dead patients were 12.78 ± 6.92 and 11.64 ± 7.36, respectively. Furthermore, in surviving patients, they were 22.19 ± 1.12 and 22.30 ± 1.22, respectively, with a P < 0.05 in each case. Based on the above tools with 95% confidence level, the area under the curve for the mortality was 0.932 for the GAP system and 0.944 for the NTS (P > 0.001). Conclusions: Both indicators could predict the mortality of patients with multitrauma. It could also be used to determine the priority of dispatch at the scene of the accident and the triage of the injured (people). Based on the results of the receiver operating characteristic curve, the NTS score has a higher accuracy.
