RESUMO
Techniques of venoarterial-extracorporeal membrane oxygenation (VA-ECMO) have improved over the decades, with numerous applications.1 Those with reversible low cardiac output benefit most from this support.1 Case of 21-year-old male, history of congenital heart disease (severe right ventricle hypoplasia and pulmonary artery stenosis with extracardiac cavo-pulmonary shunt (Fontan surgery), and atrial septal defect). Brought to the Emergency Department due to a Mallory-Weiss syndrome, upper-endoscopy "laceration at esophagogastric junction (EGJ) with active bleeding", clips were applied. However, worsening shock, repeated melenas and hematemesis, hemoglobin drop, lactate 2.8mmol/L, and needing noradrenaline (1.21mcg/kg/min). Due to active blood loss and worsening shock, the patient was intubated to maintain airway protection. Repeated upper-endoscopy "voluminous live red clot at EGJ, 4-clips and active bleeding of mucosa between, injection of polidocanol". Despite the implemented strategy, high risk of rebleeding remained. Following invasive mechanical ventilation (IMV), sustained hypotension having to increase noradrenaline (1.52mcg/kg/min) and lactate (5.8mmol/l), despite fluid resuscitation. Echocardiogram evidenced severe ventricular dysfunction, and fixed inferior vena cava (IVC) of 20mm. The heart defect combined with positive intrathoracic pressure, contributed to the worsened shock, as Fontan circulation is dependent on low vascular resistance to maintain output2. Needing VA-ECMO and admitted to ICU, volemia optimization, adjusting ventilation to lower intrathoracic pressure and started on milrinone and sildenafil. Another upper-endoscopy showed laceration at EGJ, with placement of clips. Echocardiogram revealed "Normal left ventricle. Hypoplastic right ventricle. Mild mitral regurgitation; aortic VTi 19cm. IVC 22mm. RV/RA gradient 70mmHg. Interatrial bidirectional shunt". Favorable evolution permitted extubation, suspension of milrinone and sildenafil, followed by decannulation. With rescue ECMO, congenital heart disease are salvageable despite sudden decompensation3. This case, positive intrathoracic pressure impairs the Fontan circulation, dependent on preload and higher central venous pressure to maintain cardiac output, as the ventricle is unable to compensate increased demands2, and worsening shock.

Iatrogenic inferior vena cava (IVC)-left atrium (LA) shunt is a rare complication in atrial septal defect (ASD) surgery, caused by mistaking the Eustachian valve for the lower margin of the ASD. In this report, we describe the case of a 45-year-old woman who experienced circulatory collapse at termination of cardiopulmonary bypass during surgical IVC-LA shunt repair. Transesophageal echocardiography helped identify stenosis between the IVC and the right atrium, caused by a residual original incorrectly placed ASD patch. Removal of most of the patch led to improvement in circulatory failure.

Vasoplegia describes a constellation of low vascular resistance and normal cardiac output. Vasoplegia is common after cardiac surgery in general and in heart transplant recipients more specifically and occurs in over one-half of all heart transplant recipients with a varying degree of severity. The pathophysiology of vasoplegia is multifactorial and associated with a cascade of inflammatory mediators. Routine treatment of vasoplegia is based on medical vasopressor therapy, but in severe cases this may be insufficient to maintain adequate blood pressure and does not address the underlying pathophysiology. We report a case of severe vasoplegic shock in a heart transplant recipient who was successfully managed with a multimodal therapy combination of methylene blue, immunoglobulins enriched with immunoglobulin M, cytokine adsorption, and broad-spectrum antibiotics. This represents a promising therapeutic approach for heart transplant patients with vasoplegia.

The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64-14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826-0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma.

Se presenta a un paciente con liposarcoma mediastinal gigante con dolor torácico, disnea, cuyos estudios por imágenes revelaban la presencia de una gran tumoración de 42 cm en su diámetro mayor que abarcaba todo el mediastino, comprometía ambas cavidades torácicas, rechazaba los pulmones, corazón y grandes vasos. La biopsia con aguja cortante bajo guía ecográfica fue informada como liposarcoma. El paciente tuvo resección completa del tumor mediante la incisión Clamshell. En el post operatorio inmediato, presentó shock circulatorio más disfunción multiorgánica (DOMS): plaquetopenia, insuficiencia renal aguda con necesidad de soporte dialítico, injuria hepática. El soporte y monitoreo especializado en la Unidad de Cuidados Intensivos (UCI) permitió mejoría clínica y buena evolución. Salió de alta en buenas condiciones.
We present a patient with giant mediastinal liposarcoma with chest pain, dyspnea, whose imaging studies revealed the presence of a large tumor measuring 42 cm in its greatest diameter that covered the entire mediastinum, involved both thoracic cavities, rejected the lungs, heart and big glasses. The sharp needle biopsy under ultrasound guidance was reported as liposarcoma. The patient had complete resection of the tumor through the Clamshell incision. In the immediate postoperative period, he presented circulatory shock plus multiple organ dysfunction (DOMS): plateletopenia, acute renal failure with the need for dialytic support, liver injury. Specialized support and monitoring in the Intensive Care Unit (ICU) allowed clinical improvement and good evolution. He was discharged in good condition.

Hepatic portal venous gas is often referred to as the "sign of death" because it signifies a very poor prognosis if appropriate treatments are not promptly administered. The etiologies of hepatic portal venous gas are diverse and include severe complex abdominal infections, mesenteric ischemia, diving, and complications of endoscopic surgery, and the clinical manifestations are inconsistent among individual patients. Thus, whether emergency surgery should be performed remains controversial. In this report, we present three cases of hepatic portal venous gas. The patients initially exhibited symptoms consistent with severe shock of unknown etiology and were treated in the intensive care unit upon admission. We rapidly identified the cause of each individual patient's condition and selected problem-directed intervention measures based on active organ support, antishock support, and anti-infection treatments. Two patients recovered and were discharged without sequelae, whereas one patient died of refractory infection and multiple organ failure. We hope that this report will serve as a valuable reference for decision-making when critical care physicians encounter similar patients.

RATIONALE: Non-paroxysmal junctional tachycardia (NPJT) is a self-limiting supraventricular tachycardia associated with primary heart disease, cardiac surgery, digitalis toxicity, and metabolic or electrolyte imbalances. However, NPJT caused enhanced normal automaticity even in the absence of structural heart disease can be fatal if not managed properly. PATIENT CONCERNS: A 74-year-old hypertensive female patient was scheduled for transureteroureterostomy and right ureteroneocystostomy under general anesthesia. DIAGNOSIS: The patient developed NPJT without visible P wave and severe hypotension due to adrenergic stimulation in response to massive hemorrhage during surgery. INTERVENTIONS: NPJT with hypotension was initially converted to sinus rhythm with normotension with administration of adenosine and esmolol. However uncontrolled surgical hemorrhage and administration of large dose of vasopressors eventually perpetuated NPJT refractory to antiarrhythmic drugs. OUTCOMES: Despite intravenous fluid resuscitation and massive transfusion, the patient was deteriorated hemodynamically due to uncontrolled bleeding and persistent NPJT, which resulted in hypovolemic shock and fatal disseminated intravascular coagulation (DIC). LESSONS: NPJT can occur by enhanced automaticity due to increased catecholamine during severe surgical hemorrhage. Although NPJT is generally self-limiting, it can be refractory to antiarrhythmic agents and accelerate hypotension if the surgical bleeding is uncontrolled. Therefore, aggressive management of the primary pathologic condition is crucial for the management of NPJT and hemodynamic collapse even in the absence of structural heart disease.

BACKGROUND: Acute type A aortic dissection (ATAAD) is a critical cardiovascular emergency that requires prompt surgical intervention for preserving life, particularly in patients with critical preoperative status. This retrospective study aimed to investigate the clinical features, early and late outcomes, and prognostic factors in patients undergoing aortic repair surgery for ATAAD complicated with preoperative shock. METHODS: Between April 2007 and July 2020, 694 consecutive patients underwent emergency ATAAD repair at our institution, including 162 (23.3%) presenting with preoperative shock (systolic blood pressure <90 mm Hg), who were classified into the survivor (n = 125) and non-survivor (n = 37) groups according to whether they survived to hospital discharge. The clinical demographics, surgical information, and postoperative complications were compared. Five-year survival and freedom from reoperation rates of survivors were analyzed using the Kaplan-Meier actuarial method. Multivariate logistic regression analysis was used to identify independent risk factors for in-hospital mortality. RESULTS: The in-hospital surgical mortality rate in patients with ATAAD and shock was 22.8%. The non-survivor group showed higher rates of preoperative cardiopulmonary resuscitation, acute myocardial infarction, and cerebral infarction, and was associated with longer cardiopulmonary bypass time, higher rates of total arch replacement and intraoperative extracorporeal membrane oxygenation implementation. The non-survivor group had higher blood transfusion volumes and rates of malperfusion-related complications. Multivariate analysis revealed that preoperative cardiopulmonary resuscitation, prolonged cardiopulmonary bypass time, and total arch replacement were risk factors for in-hospital mortality. For patients who survived to discharge, the 5-year cumulative survival and freedom from aortic reoperation rates were 75.6% (95% confidence interval, 67.6%-83.6%) and 82.6% (95% confidence interval, 74.2%-91.1%), respectively. CONCLUSIONS: Preoperative shock in ATAAD is associated with a high risk of in-hospital mortality, particularly in patients who undergo cardiopulmonary resuscitation and complex aortic repair procedures with extended cardiopulmonary bypass. However, late outcomes are acceptable for patients who were stabilized through surgical treatment and survived to discharge.

A case of massive overdose of sustained release bupropion tablets is described. The patient presented with GCS 3, tachycardic and in vasoplegic shock. ECHO and EKG were initially normal. The hemodynamic situation was stabilised with vasopressors, but 18 h after presentation the patient deteriorated with wide complex arrhythmias rapidly progressing to cardiac arrest. The patient was put on VA-ECMO after 35 minutes of CPR. Circulation could be stabilized and ECMO was discontinued after 36 h. The patient was extubated on day 6 and made a complete recovery on discharge two weeks after presentation. At 34h, with ongoing ECMO, 236 tablets (with visible print identifying them as bupropion) were evacuated from the patient's stomach by gastroscopy. The tablets were analysed by NMR (nuclear magnetic resonance) but no longer contained any active substance. Blood levels of bupropion and hydroxybupropion at 36h were 790 and 1300 µg/l. The case illustrates a worrying surge in serious bupropion poisonings as noted by the Swedish Poisons Information Centre during the last 5 years.

Objetivos: Millones de pacientes con COVID-19 fueron internados en terapia intensiva en el mundo, la mitad desarrollaron síndrome de dificultad respiratoria aguda (SDRA) y recibieron ventilación mecánica invasiva (VMI), con una mortalidad del 50%. Analiza-mos cómo edad, comorbilidades y complicaciones, en pacientes con COVID-19 y SDRA que recibieron VMI, se asociaron con el riesgo de morir durante su hospitalización.Métodos: Estudio de cohorte observacional, retrospectivo y multicéntrico realizado en 5 hospitales (tres privados y dos públicos universitarios) de Argentina y Chile, durante el segundo semestre de 2020.Se incluyeron pacientes >18 años con infección por SARS-CoV-2 confirmada RT-PCR, que desarrollaron SDRA y fueron asistidos con VMI durante >48 horas, durante el se-gundo semestre de 2020. Se analizaron los antecedentes, las comorbilidades más fre-cuentes (obesidad, diabetes e hipertensión), y las complicaciones shock, insuficiencia renal aguda (IRA) y neumonía asociada a la ventilación mecánica (NAV), por un lado, y las alteraciones de parámetros clínicos y de laboratorio registrados.Resultados: El 69% era varón. La incidencia de comorbilidades difirió para los diferentes grupos de edad. La mortalidad aumentó significativamente con la edad (p<0,00001). Las comorbilidades, hipertensión y diabetes, y las complicaciones de IRA y shock se asociaron significativamente con la mortalidad. En el análisis multivariado, sólo la edad mayor de 60 años, la IRA y el shock permanecieron asociados con la mortalidad. Conclusiones: El SDRA en COVID-19 es más común entre los mayores. Solo la edad >60 años, el shock y la IRA se asociaron a la mortalidad en el análisis multivariado.
Objectives: Millions of patients with COVID-19 were admitted to intensive care world-wide, half developed acute respiratory distress syndrome (ARDS) and received invasive mechanical ventilation (IMV), with a mortality of 50%. We analyzed how age, comor-bidities and complications in patients with COVID-19 and ARDS who received IMV were associated with the risk of dying during their hospitalization.Methods: Observational, retrospective and multicenter cohort study carried out in 5 hospitals (three private and two public university hospitals) in Argentina and Chile, during the second half of 2020.Patients >18 years of age with SARS-CoV-2 infection confirmed by RT-PCR, who devel-oped ARDS and were assisted with IMV for >48 hours, during the second half of 2020, were included. History, the most frequent comorbidities (obesity, diabetes and hyper-tension) and the complications of shock, acute renal failure (AKI) and pneumonia as-sociated with mechanical ventilation (VAP), on the one hand, and the alterations of re-corded clinical and laboratory parameters, were analyzed.Results: 69% were men. The incidence of comorbidities differed for different age groups. Mortality increased significantly with age (p<0.00001). Comorbidities, hyper-tension and diabetes, and complications of ARF and shock were significantly associat-ed with mortality. In the multivariate analysis, only age over 60 years, ARF and shock remained associated with mortality.Conclusions: ARDS in COVID-19 is more common among the elderly. Only age >60 years, shock and ARF were associated with mortality in the multivariate analysis

We aimed to explore the association between FFP transfusion and outcomes of DC patients with significant coagulopathy. A total of 693 DC patients with significant coagulopathy were analyzed with 233 patients per group after propensity score matching (PSM). Patients who received FFP transfusion were matched with those receiving conventional therapy via PSM. Regression analysis showed FFP transfusion had no benefit in 30-day (HR: 1.08, 95% CI 0.83-1.4), 90-day (HR: 1.03, 95% CI 0.80-1.31) and in-hospital(HR: 1.30, 95% CI 0.90-1.89) mortality, associated with increased risk of liver failure (OR: 3.00, 95% CI 1.78-5.07), kidney failure (OR: 1.90, 95% CI 1.13-3.18), coagulation failure (OR: 2.55, 95% CI 1.52-4.27), respiratory failure (OR: 1.76, 95% CI 1.15-2.69), and circulatory failure (OR: 2.15, 95% CI 1.27-3.64), and even associated with prolonged the LOS ICU (ß: 2.61, 95% CI 1.59-3.62) and LOS hospital (ß: 6.59, 95% CI 2.62-10.57). In sensitivity analysis, multivariate analysis (HR: 1.09, 95%CI 0.86, 1.38), IPTW (HR: 1.11, 95%CI 0.95-1.29) and CAPS (HR: 1.09, 95% CI 0.86-1.38) showed FFP transfusion had no beneficial effect on the 30-day mortality. Smooth curve fitting demonstrated the risk of liver failure, kidney failure and circulatory failure increased by 3%, 2% and 2% respectively, for each 1 ml/kg increase in FFP transfusion. We found there was no significant difference of CLIF-SOFA and MELD score between the two group on day 0, 3, 7, 14. Compared with the conventional group, INR, APTT, and TBIL in the FFP transfusion group significantly increased, while PaO2/FiO2 significantly decreased within 14 days. In conclusion, FFP transfusion had no beneficial effect on the 30-day, 90-day, in-hospital mortality, was associated with prolonged the LOS ICU and LOS hospital, and the increased risk of liver failure, kidney failure, coagulation failure, respiratory failure and circulatory failure events. However, large, multi-center, randomized controlled trials, prospective cohort studies and external validation are still needed to verify the efficacy of FFP transfusion in the future.

In order to analyze the clinical characteristics of death cases in the oral emergency department of the stomatological hospital, and to improve the first aid technique before and in hospitals, we collected the clinical data of death cases in the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2010 to January 2023 for retrospective analysis. General cha-racteristics, such as the patients' gender, age, chief complaint, maxillofacial diseases, systemic underlying diseases, rescue situation, cause of death and seasonal distribution of death were summarized. The results showed that a total of 8 death cases (5 males and 3 females) occurred during the 13-year period, ranging in age from 40 to 86 years, with a median age of 66 years. Among the 8 patients, 5 reported bleeding from oral cancer, 1 reported chest tightness and dyspnea after oral cancer surgery, 1 reported loss of consciousness after maxillofacial trauma, and 1 reported oral erosion and aphagia. All the 8 patients had one or more underlying diseases, such as hypertension, coronary heart disease, diabetes, renal failure, and cerebral infarction, etc. and 2 of them showed dyscrasia. Among them, the cause of death in 5 cases was respiratory and circulatory failure caused by oral cancer rupture and hemorrhage or poor surgical wound healing and hemorrhage; 1 case was uremia and hyperkalemia leading to circulatory failure; 1 case was asphyxia caused by swelling of oral floor tissue after maxillofacial trauma; and the other case was acute myocardial infarction caused circulatory failure after oral cancer surgery. According to the vital state at the time of treatment, 6 patients had loss of consciousness, respiratory and cardiac arrest before hospital, and 2 patients suffered from loss of consciousness, respiratory and cardiac arrest during treatment. All the patients received cardiopulmonary resuscitation and some advanced life support measures, and the average rescue time was 46 min. Due to the low incidence of death in the oral emergency department, medical personel have little experience in first aid. First aid training and drills and assessment should be organized regularly. First aid facilities should be always available and regularly maintained by special personnel, such as electrocardiogram (ECG) monitor, defibrillator, simple breathing apparatus, oxygen supply system, negative pressure suction system, endotracheal intubation and tracheotomy equipment. The death cases mainly occurred in the elderly patients with oral cancer bleeding and systemic underlying diseases. Education of emergency awareness for the elderly patients with oral cancer after surgery should be enhanced. Medical staff should strengthen first aid awareness and skills.

A man in his late 70s with chronic myelomonocytic leukaemia presented for evaluation of acute leukaemic transformation and initiation of cytoreductive therapy after being found to have asymptomatic hyperleucocytosis. Within 24 hours, the patient developed vasopressor-refractory shock, severe lactic acidosis and multiorgan failure. Serial echocardiographic assessments revealed interval enlargement of the right ventricle with development of the McConnell's sign, and abdominal CT showed diffuse bowel wall thickening, likely due to ischaemia. CT angiography excluded pulmonary embolism or occlusion of intra-abdominal arteries. Despite aggressive care, the patient died from cardiovascular collapse within 8 hours of the onset of hypotension. An autopsy revealed extensive infiltration of early myeloid cells in pulmonary, myocardial, hepatic and intestinal microvasculature. This case illustrates different mechanisms by which leucostasis causes acute cardiovascular collapse and stresses the emergent nature of this diagnosis.

BACKGROUND: Hemorrhage control is a time-critical task, and recent studies have demonstrated that a shorter time to definitive care is positively associated with patient survival and functional outcomes. The concept of direct transport to the operating room was proposed in the 1960s to reduce treatment time. Some trauma centers have developed protocols for direct-to-operating room resuscitation (DOR) programs. Moreover, few studies have reported the clinical outcomes of DOR in patients with trauma; however, their clinical effect in improving the efficiency and quality of care remains unclear. In this systematic review, we aimed to consolidate all published studies reporting the effect of DOR on severe trauma and evaluate its utility. METHODS: The PubMed, EMBASE, and Cochrane databases were searched from inception to April 2023, to identify all articles published in English that reported the effect of direct-to-operating room trauma resuscitation for severe trauma. The articles were reviewed as references of interest. RESULTS: We reviewed six studies reporting the clinical effect of operating room trauma resuscitation. A total of 3232 patients were identified. Five studies compared the actual mortality with the predicted mortality using the trauma score and injury severity score, while one study compared mortality using propensity matching. Four studies reported that the actual survival rate for overall injuries was better than the predicted survival rate, whereas two studies reported no difference. Some studies performed subgroup analyses. Two studies showed that the survival rate for penetrating injuries was better than the predicted survival rate, and one showed that the survival rate for blunt injuries was better than the predicted survival rate. Five studies reported the time to surgical intervention, which was within 30 min. Two studies time-compared surgical intervention, which was shorter in patients who underwent DOR. CONCLUSION: Implementing DOR is likely to have a beneficial effect on mortality and can facilitate rapid intervention in patients with severe shock. Future studies, possibly clinical trials, are needed to ensure a proper comparison of the efficiency.

PURPOSE: Shock Index is used to predict injury severity and adverse outcomes in trauma patients, but pediatric age-adjusted shock index (SIPA) has superior performance in pediatric patients older than 1 year. Pediatric age-adjusted shock index scores younger than 1 year have not been well studied. This project aimed to establish and evaluate SIPA cut point data points for patients younger than 1 year. METHODS: Using age-based vital signs, we developed cut point values for patients younger than 1 year using our institutional trauma data. All trauma patients younger than 12 months were included, and clinical outcomes were recorded. Pediatric age-adjusted shock index cut points were defined using age-specific vital sign limits (SIPA-VS) and tested against optimal cut points defined by receiver operating characteristic analysis (SIPA-ROC) and a cut point of 1.2 (SIPA-Nordin), which is used for patients aged 1 to 4 years. Student's t test, χ 2 tests, analysis of variance, and test characteristics were used to analyze groups. RESULTS: A total of 609 pediatric trauma patients younger than 12 months were identified from 2018 to 2022. Pediatric age-adjusted shock index scores were calculated for 483 patients. There were 406 patients with blunt trauma and 17 with penetrating. SIPA-Nordin was elevated in 81.6% (n = 397) of patients, compared with SIPA-VS 21% (n = 101) and SIPA-ROC 31% (n = 150). In comparison with SIPA-Nordin, both SIPA-VS and SIPA-ROC score exhibited superior specificity and negative predictive values for multiple outcomes. Elevated SIPA-ROC scores had statistically significant associations with intensive care unit admission, mechanical ventilation, severe anemia, transfusion during hospital admission, and in-hospital mortality. CONCLUSION: Pediatric age-adjusted shock index is a useful tool in identifying patients at risk for several complications of severe traumatic injury. Pediatric age-adjusted shock index cut points had high negative predictive value and specificity for many outcomes. This study proposes cut point values that may aid in clinical decision making for trauma patients younger than 1 year. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level IV.

PURPOSE: Vital signs are important for predicting clinical outcomes in patients with trauma. However, their accuracy can be affected in older adults because hemodynamic changes are less obvious. This study aimed to examine the usefulness of changes in vital signs during transportation in predicting the need for hemostatic treatments in older patients with trauma. METHODS: This retrospective cohort study was conducted using data from the Japan Trauma Data Bank (2004-2019). Patients aged ≥ 65 years who were hemodynamically stable at the scene were included in this study. The incidence of emergency surgery within 12 h after hospital arrival was compared between patients with delta Shock Index (dSI) > 0.1 and those with dSI ≤ 0.1. Predicting ability was examined after adjusting for patient demographics, comorbidities, vital signs at the scene and on hospital arrival, Injury Severity Score, and abbreviated injury scale in each region. RESULTS: Among the 139,242 patients eligible for the study, 3,701 underwent urgent hemostatic surgery within 12 h. Patients with dSI > 0.1 showed a significantly higher incidence of emergency surgery than those with dSI ≤ 0.1 (871/16,549 [5.3%] vs. 2,830/84,250 [3.4%]; odds ratio (OR), 1.60 [1.48-1.73]; adjusted OR, 1.22 [1.08-1.38]; p = 0.001). The relationship between high dSI and a higher incidence of intervention was observed in patients with hypertension and those with decreased consciousness on arrival. CONCLUSION: High dSI > 0.1 was significantly associated with a higher incidence of urgent hemostatic surgery in older patients.

BACKGROUND: Timely identification of high-risk pediatric trauma patients and appropriate resource mobilization may lead to improved outcomes. We hypothesized that reverse shock index times the motor component of the Glasgow Coma Scale (GCS) (rSIM) would perform equivalently to reverse shock index times the total GCS (rSIG) in the prediction of mortality and the need for intervention following pediatric trauma. METHODS: The 2017-2020 National Trauma Data Bank data sets were used. We included all patients 16 years or younger who had a documented prehospital and trauma bay systolic blood pressure, heart rate, and total GCS. We excluded all patients who arrived at the trauma center without vital signs and interfacility transport patients. Receiver operating characteristic curves were used to model the performance of each metric as a classifier with respect to our primary and secondary outcomes, and the area under the receiver operating characteristic curve (AUROC) was used for comparison. Our primary outcome was mortality before hospital discharge. Secondary outcomes included blood product administration or hemorrhage control intervention (surgery or angiography) <4 hours following hospital arrival and intensive care unit admission. RESULTS: After application of exclusion criteria, 77,996 patients were included in our analysis. Reverse shock index times GCS-motor and rSIG performed equivalently as predictors of mortality in the 1- to 2- ( p = 0.05) and 3- to 5-year-old categories ( p = 0.28), but rSIM was statistically outperformed by rSIG in the 6- to 12- (AUROC, 0.96 vs. 0.95; p = 0.04) and 13- to 16-year-old age categories (AUROC, 0.96 vs. 0.95; p < 0.01). Reverse shock index times GCS-motor and rSIG also performed similarly with respect to prediction of secondary outcomes. CONCLUSION: Reverse shock index times GCS-total and rSIM are both outstanding predictors of mortality following pediatric trauma. Statistically significant differences in favor of rSIG were noted in some age groups. Because of the simplicity of calculation, rSIM may be a useful tool for pediatric trauma triage.
