Effectiveness of Combined Application of Shock Index and Early Warning Scoring System in Patients with Acute Gastrointestinal Hemorrhage

Objective:To explore the effect of the combined application of the Shock Index(SI)and the Early Warning Score(EWS)in patients with acute gastrointestinal bleeding.Methods:Seventy patients with acute gastrointestinal bleeding admitted to a hospital from June 2022 to May 2024 were selected and randomly divided into two groups:the control group and the observation group,with 35 patients in each group.The control group received conventional emergency care measures,while the observation group received SI combined with NEWS emergency care measures.The treatment effects in both groups were compared.Results:The observation group had shorter waiting times for consultation(4.45±1.59 minutes),intravenous access establishment(6.79±2.52 minutes),hemostasis time(4.41±1.52 hours),and hospital stays(8.39±2.13 days)compared to the control group,which had times of 5.46±1.34 minutes,8.41±2.16 minutes,5.16±1.47 hours,and 10.26±2.98 days,respectively.The differences were statistically significant(P<0.05).Before management,there were no significant differences in the levels of hemoglobin,prealbumin,and serum protein between the two groups(P>0.05).However,after systematic emergency management,the serum indexes in both groups significantly improved,with the observation group showing greater improvement than the control group,and these differences were statistically significant(P<0.05).In the observation group,only one case of cardiovascular complications occurred during the rescue period,with an incidence rate of 2.86%.In contrast,the control group experienced eight cases of complications,including hemorrhagic shock,anemia,multi-organ failure,cardiovascular complications,and gastrointestinal rebleeding,with an incidence rate of 22.85%.The difference between the groups was statistically significant(P<0.05).Conclusion:The application of SI combined with EWS emergency care measures in patients with acute gastrointestinal hemorrhage can effectively improve serum indexes,shorten resuscitation time and hospital stay,and reduce the risk of complications such as hemorrhagic shock,anemia,infection,multi-organ failure,cardiovascular complications,acute renal failure,and gastrointestinal rebleeding.This approach has positive clinical application value.

Comparing 11 early warning scores and three shock indices in early sepsis prediction in the emergency department

BACKGROUND:This study aimed to evaluate the discriminatory performance of 11 vital sign-based early warning scores(EWSs)and three shock indices in early sepsis prediction in the emergency department(ED).METHODS:We performed a retrospective study on consecutive adult patients with an infection over 3 months in a public ED in Hong Kong.The primary outcome was sepsis(Sepsis-3 definition)within 48 h of ED presentation.Using c-statistics and the DeLong test,we compared 11 EWSs,including the National Early Warning Score 2(NEWS2),Modified Early Warning Score,and Worthing Physiological Scoring System(WPS),etc.,and three shock indices(the shock index[SI],modified shock index[MSI],and diastolic shock index[DSI]),with Systemic Inflammatory Response Syndrome(SIRS)and quick Sequential Organ Failure Assessment(qSOFA)in predicting the primary outcome,intensive care unit admission,and mortality at different time points.RESULTS:We analyzed 601 patients,of whom 166(27.6%)developed sepsis.NEWS2 had the highest point estimate(area under the receiver operating characteristic curve[AUROC]0.75,95%CI 0.70-0.79)and was significantly better than SIRS,qSOFA,other EWSs and shock indices,except WPS,at predicting the primary outcome.However,the pooled sensitivity and specificity of NEWS2≥5 for the prediction of sepsis were 0.45(95%CI 0.37-0.52)and 0.88(95%CI 0.85-0.91),respectively.The discriminatory performance of all EWSs and shock indices declined when used to predict mortality at a more remote time point.CONCLUSION:NEWS2 compared favorably with other EWSs and shock indices in early sepsis prediction but its low sensitivity at the usual cut-off point requires further modification for sepsis screening.

Application of pulse index continuous cardiac output system in elderly patients with acute myocardial infarction complicated by cardiogenic shock: A prospective randomized study

BACKGROUND Cardiogenic shock (CS) secondary to acute myocardial infarction (AMI) complicates management of the condition, and often leads to poor prognosis. Prompt and accurate monitoring of cardiovascular and accompanying hemodynamic changes is crucial in achieving adequate management of the condition. Advances in technology has availed procedures such as pulse index continuous cardiac output (PiCCO), which can offer precise monitoring of cardiovascular functions and hemodynamic parameters. In this study, PiCCO is evaluated for its potential utility in improving management and clinical outcomes among elderly patients with AMI complicated by CS. AIM To assess whether use of the PiCCO system can improve clinical outcomes in elderly patients with AMI complicated by CS.METHODS Patients from emergency intensive care units (EICU) or coronary care units (CCU) were randomized to receive PiCCO monitoring or not. The APACHE II score, SOFA score, hs-TnI, NT-proBNP, PaO2/FiO2 ratio and lactate levels on day 1, 3 and 7 after treatment were compared. The infusion and urine volume at 0-24 h, 24-48 h and 48-72 h were recorded, as were the cardiac index (CI), extravascular lung water index (EVLWI), intrathoracic blood volume index (ITBVI) and global end diastolic volume index (GEDVI) at similar time intervals. RESULTS Sixty patients with AMI complicated by CS were included in the study. The PiCCO group had a significantly lower APACHE II score, SOFA score, hs-TnI and NT-proBNP levels on day 1, 3 and 7 after treatment. The infusion and urine volume during 0-24 h in the PiCCO group were significantly greater, and this group also showed significantly higher ADL scores. Furthermore, the PiCCO group spent lesser days on vasoactive agents, mechanical ventilation, and had a reduced length of stay in EICU/CCU. Additionally, the CI was significantly higher at 48 h and 72 h in the PiCCO group compared with that at 24 h, and the EVLWI, ITBVI and GEDVI were significantly decreased at 48 h and 72 h. CONCLUSION Applying the PiCCO system could improve the clinical outcomes of elderly patients with AMI complicated by CS.

Modified shock index and mortality rate of emergency patients

BACKGROUND:This study aimed to determine whether modified shock index(MSI)is associated with mortality that is superior to heart rate,blood pressure,or the shock index(SI).in emergency patients.METHODS:A retrospective database review was performed on 22 161 patients who presented to Peking Union Medical College Hospital Emergency Department and received intravenous fluids from January 1 to December 31,2009.We gathered data of the patients on age,gender,vital signs,levels of consciousness,presenting complaints,and SI and MSI were calculated for all patients.RESULTS:Multivariate regression analysis was performed to determine the correlation between risk factors and outcome.There is a significant correlation between emergency patient mortality rate and patient's vital signs obtained at the triage desk(HR>120 beats/min,systolic BP<90 mmHg,diastolic BP<60 mmHg).MSI is a stronger predictor of emergency patient mortality compared to heart rate and blood pressure alone,whereas SI does not have a significant correlation with emergency patient mortality rate.CONCLUSION:MSI is a clinically significant predictor of mortality in emergency patients.It may be better than using heart rate and blood pressure alone.SI is not significantly correlated with the mortality rate of the emergency patient.

Correlation of Inferior Vena Cava Respiratory Variability Index with Central Venous Pressure and Hemodynamic Parameters in Ventilated Pigs with Septic Shock

Septic shock is a common critical condition, for which effective early fluid resuscitation is the therapeutic focus. According to the 2008 international guidelines for management of severe sepsis and septic shock, resuscitation should achieve a central venous pressure （CVP） of 8-12 mmHg within the first 6 h. However, it is still uncertain about the sensitivity and specificity of CVP in reflecting the cardiac preload. Ultrasonography is a simple, rapid, non-invasive, and repeatable method for the measurement of sensitivity and specificity of CVP and has thus gradually attracted the increasing attention of physicians. It was reported that ultrasonography can show the inferior vena cava diameter, respiratory variability index, and blood volume in patients with sepsis or heart failure.

Shock index of patients with sepsis after continuous blood purification treatment and its relationship with systemic inflammatory response syndrome and immune response

Objective:To study the shock index of patients with sepsis after continuous blood purification (CBP) treatment and its relationship with systemic inflammatory response syndrome and immune response.Methods:A total of 88 patients with sepsis who underwent continuous blood purification treatment in our hospital between June 2012 and May 2016 were chosen as research subjects, shock index (SI) was compared before and after the treatment, and according to the level of SI after treatment, all patients were divided into shock group (n=27) with SI>0.5 points and no shock group (n=61) with SI≤0.5 points. Serum contents of inflammatory mediators, Th1/Th2 cellular immunity indexes, immunoglobulin and complement were compared between two groups of patients after treatment.Results: The level of SI in patients with sepsis was significantly lower than that before treatment. Serum contents of inflammatory mediators PCT, CRP and HMGB1 in no shock group were lower than those in shock group, contents of Th1 cytokines IL-2 and IFN-γ were higher than those in shock group, contents of Th2 cytokines IL-10 and IL-13 were lower than those in shock group, and contents of IgG, IgM, IgA, C3 and C4 were higher than those in shock group.Conclusion: The level of SI decreases in the patients with sepsis after CBP treatment, and SI level is directly correlated with the systemic inflammatory response syndrome and immune response levels.

Validation of the age-adjusted shock index for pediatric casualties in Iraq and Afghanistan

Background: Pediatric casualties account for a notable proportion of encounters in the deployed setting based on the humanitarian medical care mission. Previously published data demonstrates that an age-adjust shock index may be a useful tool in predicting massive transfusion and death in children. We seek to determine if those previous findings are applicable to the deployed, combat trauma setting.Methods: We queried the Department of Defense Trauma Registry(DODTR) for all pediatric subjects admitted to US and Coalition fixed-facility hospitals in Iraq and Afghanistan from January 2007 to January 2016. This was a secondary analysis of casualties seeking to validate previously published data using the shock index, pediatric age adjusted. We then used previously published thresholds to determine patients outcome for validation by age grouping, 1–3 years(1.2), 4–6 years(1.2), 7–12 years(1.0), 13–17 years(0.9).Results: From January 2007 through January 2016 there were 3439 pediatric casualties of which 3145 had a documented heart rate and systolic pressure. Of those 502(16.0%) underwent massive transfusion and 226(7.2%) died prior to hospital discharge. Receiver operating characteristic(ROC) thresholds were inconsistent across age groups ranging from 1.0 to 1.9 with generally limited area under the curve(AUC) values for both massive transfusion and death prediction characteristics. Using the previously defined thresholds for validation, we reported sensitivity and specificity for the massive transfusion by age-group: 1–3(0.73, 0.35), 4–6(0.63, 0.60), 7–12(0.80, 0.57), 13–17(0.77, 0.62). For death, 1–3(0.75, 0.34), 4–6(0.66–0.59), 7–12(0.64, 0.52), 13–17(0.70, 0.57). However, negative predictive values(NPV) were generally high with all greater than 0.87.Conclusions: Within the combat setting, the age-adjusted pediatric shock index had moderate sensitivity and relatively poor specificity for predicting massive transfusion and death. Better scoring systems are needed to predict resource needs prior to arrival, that perhaps include other physiologic metrics. We were unable to validate the previously published findings within the combat trauma population.

Application and Nursing of Pulse Index Continuous Cardiac Output (PiCCO) Volume Monitoring in Early Fluid Resuscitation in Patients with Septic Shock

Background: Septic shock is a rapidly changing and fatal syndrome that can cause comprehensive deterioration of cardiopulmonary and renal function and multiple organ failure. At the same time, septic shock has the complex clinical manifestations and hemodynamics. PiCCO can accurately monitor blood flow, physical and volume indicators, and active and effective fluid resuscitation are important measures to reduce the fatality rate of septic shock and improve the prognosis of patients. Objectives: To explore the application and nursing of PiCCO in early fluid resuscitation in patients with septic shock. Methods: This was a retrospective observational study. The observation group and the control group each had 30 cases. The observation group used PiCCO to guide fluid resuscitation;the control group used conventional methods to guide fluid resuscitation. The changes in CVP, HR, MAP, and urine volume per hour were observed in the two groups. The changes of various indicators before and after fluid resuscitation, the length of stay in ICU and the mortality rate were compared between the two groups. All the outcomes were collected from the electronic medical case system after patients’ discharge from the hospital. Results: APACHE II, CVP, HR, MAP were compared between the observation group and the control group, and the differences were statistically significant (P < 0.05). The blood volume of patients in the observation group was significantly improved after fluid supplementation (P < 0.05). Compared with the control group, the length of stay in ICU in the observation group was significantly shorter, and the mortality rate was also significantly reduced (P < 0.05). Conclusion: PiCCO can be better used in early fluid resuscitation of patients with septic shock.

Diagnostic Performance of Serial bedside Capillary Lactate, Hemoglobin, and Shock Index for Severe Postpartum

Objective: To assess the diagnostic capacity of bedside capillary lactate (CLact), capillary Haemoglobin (CHb), and shock index (SI) for severe postpartum haemorrhage (SPPH > 2000 ml) at diagnosis, 15 minutes and 30 minutes later. Method: A cohort study was carried out in a reference hospital in San Luis Potosi, Mexico from February 2020 to March 2021, and included sixty women in vaginal labor or c-section who presented PPH (≥500 ml in labor or ≥1000 ml in c-section) measured by the gravimetric method. CLact, SI, and CHb concentrations were analyzed at diagnosis of PPH, 15 minutes, and 30 minutes. Patients who presented total blood loss of >2000 ml were considered SPPH. A T-test or Wilcox test was performed to compare the groups of non-severe and severe. Sensitivity, specificity, and performance were calculated by A Receiver Operating Curve. Results: A CLact measurement at 30 minutes was significantly different between the non-severe and severe groups (4.0 + 1.9 vs 4.8 + 1.15 P-value 0.001, with an optimal cut point of 4.3 mmol/dl at AUC 0.75, sensitivity 0.85, and specificity of 0.62. With a cut-point of 1.17, an AUC of 0.76, sensitivity of 0.43, and specificity of 0.98, SI at diagnosis was significantly different between the non-severe and severe groups (0.70 + 0.20 vs. 0.90 + 0.38 P-value 0.0228). Conclusion: SI is an early sign of SPPH;CLact can significantly identify SPPH after 30 minutes.

Correlation between shock index and inflammation, oxidative stress as well as target organ damage in patients with sepsis

Objective:To study the correlation between shock index and inflammation, oxidative stress as well as target organ damage in patients with sepsis.Methods: A total of 70 patients with sepsis treated in our hospital between March 2013 and May 2016 were collected and divided into no shock group (SI<0.5) (n=11), general shock group (0.5 SI 2) (n=42) and severe shock group (SI>2.0) (n=17) according to the shock index (SI). Immediately after admission, serum levels of inflammatory factors, oxidative stress indexes and liver function indexes were detected.Results:Serum interleukin-1β (IL-1β), interleukin-8 (IL-8), tumor necrosis factor (TNF-α), advanced oxidation protein products (AOPPs), total bilirubin (TB),γ-glutamyl transpeptidase (GGT) and alanine aminotransferase (ALT) levels of severe shock group and general shock group were higher than those of no shock group while anti-inflammatory factors interleukin-10 (IL-10), interleukin-13 (IL-13), soluble tumor necrosis factor receptorⅠ(sTNF-RI), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) and catalase (CAT) levels were lower than those of no shock group;serum IL-1β, IL-8, TNF-α, AOPPs, TB, GGT and ALT levels of severe shock group were higher than those of general shock group while IL-10, IL-13, sTNF-RI, CAT, GSH-Px and SOD levels were lower than those of general shock group.Conclusion:The higher the shock index in patients with sepsis, the more severe the inflammation, oxidative stress and target organ damage, and the two are positively correlated.

Testing the Proposed Municipality Resilience Index to Climate Change Shocks and Stresses in Mbale Municipality in Eastern Uganda

Since climate change shocks and stresses cannot be fully prevented, building resilient urban areas is gaining more attention in the global community. By building resilience, the negative impacts of climate change shocks and stresses can be alleviated. Several indices have been developed to measure urban resilience. Yet, most of these indices focus more on objective methods which require robust bio-physical and socio-economic data sets which are generally lacking in many developing countries. To reduce this challenge, the use of subjective methods has recently been suggested. This study proposed and tested a Municipality Resilience Index (MRI) which employed a subjective method to assess the resilience of Mbale municipality in Eastern Uganda against climate change shocks and stresses. The proposed MRI includes 46 variables describing the physical, social, economic and institutional dimensions. The MRI can be applied in any municipality in developing countries facing climate related shocks and stresses and with limited survey data. The application of this index to Mbale municipality shows that the municipality has a low resilience index of 0.2. Similarly, most variables in the four dimensions of resilience reflected very low resilience scores with other divisions being more resilient than the others. Furthermore, the social dimension has the lowest score as compared to the physical, economic and institutional dimensions. The findings indicate a spatial variability in the contribution of the resilience dimensions within this small geographic confine. Moreover, the findings show the strengths and weaknesses in the different dimensions of the proposed MRI. This can act as a guide for policy and practitioners on which sectors to target in order to enhance the resilience of Mbale municipality.

Wearable Smart Sensor System for Medical Monitoring with an Assessment of the Level of Blood Loss and Pain Shock Because of Trauma or Injury

Blood loss in peacetime is mainly due to the normal menstrual cycle in women or diseases with surgical intervention. In wartime, blood loss in military personnel is a characteristic sign of a closed or open injury of the body during internal or external bleeding. Access to clinical care for wounded military personnel injured on the battlefield is limited and has long delays compared to patients in peacetime. Most of the deaths of wounded military personnel on the battlefield occur within the first hour after being wounded. The most common causes are delay in providing medical care, loss of time for diagnosis, delay in stabilization of pain shock and large blood loss. Some help in overcoming these problems is provided by the data in the individual capsule, which each soldier of the modern army possesses;however, data in an individual capsule is not sufficient to provide emergency medical care in field and hospital conditions. This paper considers a project for development of a smart real-time monitoring wearable system for blood loss and level of shock stress in wounded persons on the battlefield, which provides medical staff in field and hospital conditions with the necessary information to give timely medical care. Although the hospital will require additional information, the basic information about the victims will already be known before he enters the hospital. It is important to emphasize that the key term in this approach is monitoring. It is tracking, and not a one-time measurement of indicators, that is crucial in a valid definition of bleeding.

目的探讨并分析急诊多发伤患者rSIG休克指数、初始血乳酸及D二聚体(D-D)变化。方法选取本院2021年6月至2023年7月接诊的68例急诊多发伤患者的病历资料,根据治疗结局分为死亡组7例、存活组61例。根据损伤严重程度评分(ISS)对68例急诊多发伤患者进行划分,其中轻中度伤组55例(ISS评分≤25分)、重伤组13例(ISS评分>25分)。比较死亡组和存活组、轻中度伤组和重伤组急诊多发伤患者rSIG休克指数、初始血乳酸及D-D水平变化,采用Pearson相关分析法分析急诊多发伤rSIG休克指数、初始血乳酸及D-D水平与预后及损伤严重程度的相关性。结果死亡组患者的rSIG休克指数、初始血乳酸及D-D水平均明显高于存活组(P<0.05);重伤组患者的rSIG休克指数、初始血乳酸及D-D水平均明显高于轻中度伤组(P<0.05);经Pearson相关分析结果显示,急诊多发伤的rSIG休克指数、初始血乳酸及D二聚体水平与预后及损伤严重程度均呈正相关(P<0.05)。结论r SIG休克指数、初始血乳酸及D-D变化均与急性多发伤患者的死亡风险和不良预后密切相关。在急诊救治中,监测这些指标可以为医生提供重要的参考依据,有助于评估患者的病情和预后,从而制定更加合理的治疗方案。
