1. Age shock index, shock index, and modified shock index for predicting postintubation hypotension in the emergency department. (PubMed)

Age shock index, shock index, and modified shock index for predicting postintubation hypotension in the emergency department. Hypotension after emergent ETI is a relatively common complication during and after emergency airway management. We aimed to evaluate SI, MSI, and age SI to predict PIH in patients who presented to the emergency department. Moreover, which factors would be better for predicting the event or similar to the others.A retrospective, standardized chart review of consecutive (...) for prediction of PIH was better than MSI and SI (p = 0.006 for age SI versus MSI, p = 0.005 for age SI versus SI).Preintubation age SI, MSI, and SI are all independent predictors of PIH in patients who need emergent intubation. Aong these parameters, age SI is the best marker to predict the outcome. Calculation of these indexes are simple and could be an guide of implement to prevent hypotension after ETI.Copyright © 2019 Elsevier Inc. All rights reserved.

2. Shock index and pediatric specific shock index

Shock index and pediatric specific shock index Shock index and pediatric specific shock index – All About Cardiovascular System and Disorders Now Trending: | June 6, 2018 | | Shock index and pediatric specific shock index Shock index is a simple bedside measure introduced by Allgower and associates [1] as early as 1967. Shock index is the ratio of heart rate to systolic blood pressure. Normal range of shock index is between 0.5 and 0.7 in healthy adults . Shock index of 1.0 or more indicates (...) a poor prognosis in acute circulatory failure. Shock index of >0.9 predicts mortality in adult trauma patients. Acker SN and colleagues have developed a pediatric specific shock index: SIPA: Shock index, pediatric age adjusted [2]. SIPA is defined by maximum normal heart rate and minimum normal systolic blood pressure by age. The cut off for children were: Age 4-6: >1.22 Age 7-12: >1.0 Age 13-16: >0.9 In their retrospective review of around five hundred and fifty children presenting with trauma, 50

3. Shock index and modified shock index for prediction of myocardial damage and clinical outcome of STEMI

Shock index and modified shock index for prediction of myocardial damage and clinical outcome of STEMI Shock index and modified shock index for prediction of myocardial damage and clinical outcome of STEMI – All About Cardiovascular System and Disorders Now Trending: | June 6, 2018 | | Shock index and modified shock index for prediction of myocardial damage and clinical outcome of STEMI is the ratio of heart rate to systolic blood pressure which allows rapid bedside risk stratification [1 (...) ]. Modified shock index is the ratio of heart rate to mean arterial pressure [2]. Reinstadler SJ et al [2] used these indices to predict the myocardial damage and clinical outcome of ST segment elevation myocardial infarction (STEMI). They found that STEMI patients with elevated shock index had more severe myocardial and microvascular damage and it was associated with major adverse cardiac events (MACE) at 1 year. This multicenter study analyzed around eight hundred patients dichotomized to an admission

6. Respiratory adjusted shock index for identifying occult shock and level of Care in Sepsis Patients. (PubMed)

Respiratory adjusted shock index for identifying occult shock and level of Care in Sepsis Patients. Early identification of shock allows for timely resuscitation. Previous studies note the utility of bedside calculations such as the shock index (SI) and quick sepsis-related organ failure assessment (qSOFA) to detect occult shock. Respiratory rate may also be an important marker of occult shock. The goal of our study was to evaluate whether using a modified SI with respiratory rate would improve (...) identification of emergency department sepsis patients admitted to an ICU or stepdown unit.A prospective, observational cohort study of the respiratory adjusted shock index (RASI), defined as HR/SBP × RR/10, was conducted. RASI was calculated from triage vital signs and compared to serum lactate. Primary outcome was admission to a higher level of care defined as ICU or stepdown unit. A multivariable logistic regression model including RASI, SI, lactate, age and sex was performed with disposition

7. Validation of the Shock Index, Modified Shock Index, and Age Shock Index for Predicting Mortality of Geriatric Trauma Patients in Emergency Departments (PubMed)

Validation of the Shock Index, Modified Shock Index, and Age Shock Index for Predicting Mortality of Geriatric Trauma Patients in Emergency Departments The shock index (SI), modified shock index (MSI), and age multiplied by SI (Age SI) are used to assess the severity and predict the mortality of trauma patients, but their validity for geriatric patients is controversial. The purpose of this investigation was to assess predictive value of the SI, MSI, and Age SI for geriatric trauma patients. We (...) used the Emergency Department-based Injury In-depth Surveillance (EDIIS), which has data from 20 EDs across Korea. Patients older than 65 years who had traumatic injuries from January 2008 to December 2013 were enrolled. We compared in-hospital and ED mortality of groups categorized as stable and unstable according to indexes.

20. Inferior Vena Cava Collapsibility Index is a Valuable and Non-Invasive Index for Elevated General Heart End-Diastolic Volume Index Estimation in Septic Shock Patients (PubMed)

Inferior Vena Cava Collapsibility Index is a Valuable and Non-Invasive Index for Elevated General Heart End-Diastolic Volume Index Estimation in Septic Shock Patients BACKGROUND This study aimed to investigate the relationship between the inferior vena cava respirophasic variation (IVC collapsibility index [IVCCI]) and the general heart end-diastolic volume index (GEDVI). By determining the above relationship, we could evaluate the utility of IVCCI as an indicator. MATERIAL AND METHODS Forty (...) illustrated the best area under the curve, with a sensitivity of 100% and specificity of 100%, and a cut-off value of 12.9% to predict GEDVI <600 ml/m2 in the PRG group. CONCLUSIONS IVCCI was a good predictor of low-volume state. The IVCCI appears to be a valuable and non-invasive index for the estimation of elevated GEDVI during fluid resuscitation in septic shock patients.
