Tissue Oxygenation Does Not Predict Central Venous Oxygenation in Emergency Department Patients With Severe Sepsis and Septic Shock

ACADEMIC EMERGENCY MEDICINE, Issue 4 2010
Anthony M. Napoli MD
Abstract Objectives:, This study sought to determine whether tissue oxygenation (StO2) could be used as a surrogate for central venous oxygenation (ScVO2) in early goal-directed therapy (EGDT). Methods:, The study enrolled a prospective convenience sample of patients aged ,18 years with sepsis and systolic blood pressure <90 mm Hg after 2 L of normal saline or lactate >4 mmol, who received a continuous central venous oximetry catheter. StO2 and ScVO2 were measured at 15-minute intervals. Data were analyzed using a random coefficients model, correlations, and Bland-Altman plots. Results:, There were 284 measurements in 40 patients. While a statistically significant relationship existed between StO2 and ScVO2 (F(1,37) = 10.23, p = 0.002), StO2 appears to systematically overestimate at lower ScVO2 and underestimate at higher ScVO2. This was reflected in the fixed effect slope of 0.49 (95% confidence interval [CI] = 0.266 to 0.720) and intercept of 34 (95% CI = 14.681 to 50.830), which were significantly different from 1 and 0, respectively. The initial point correlation (r = 0.5) was fair, but there was poor overall agreement (bias = 4.3, limits of agreement = ,20.8 to 29.4). Conclusions:, Correlation between StO2 and ScVO2 was fair. The two measures trend in the same direction, but clinical use of StO2 in lieu of ScVO2 is unsubstantiated due to large and systematic biases. However, these biases may reflect real physiologic states. Further research may investigate if these measures could be used in concert as prognostic indicators.

The Use of Impedance Cardiography in Predicting Mortality in Emergency Department Patients With Severe Sepsis and Septic Shock

ACADEMIC EMERGENCY MEDICINE, Issue 4 2010
Anthony M. Napoli MD
Abstract Objectives:, Pulmonary artery catheterization poses significant risks and requires specialized training. Technological advances allow for more readily available, noninvasive clinical measurements of hemodynamics. Few studies exist that assess the efficacy of noninvasive hemodynamic monitoring in sepsis patients. The authors hypothesized that cardiac index, as measured noninvasively by impedance cardiography (ICG) in emergency department (ED) patients undergoing early goal-directed therapy (EGDT) for sepsis, would be associated with in-hospital mortality. Methods:, This was a prospective observational cohort study of patients age over 18 years meeting criteria for EGDT (lactate > 4 or systolic blood pressure < 90 after 2 L of normal saline). Initial measurements of cardiac index were obtained by ICG. Patients were followed throughout their hospital course until discharge or in-hospital death. Cardiac index measures in survivors and nonsurvivors are presented as means and 95% confidence intervals (CI). Diagnostic performance of ICG in predicting mortality was tested by receiver operating characteristic (ROC) curve and areas under the ROC curves (AUC) were compared using Wilcoxon test. Results:, Fifty-six patients were enrolled; one was excluded due to an inability to complete data acquisition. The mean cardiac index in nonsurvivors (2.3 L/min·m2, 95% CI = 1.6 to 3.0) was less than that for survivors (3.2, 95% CI = 2.9 to 3.5) with mean difference of 0.9 (95% CI = 0.12 to 1.71). The AUC for ICG in predicting mortality was 0.71 (95% CI = 0.58 to 0.88; p = 0.004). A cardiac index of < 2 L/min·m2 had a sensitivity of 43% (95% CI = 18% to 71%), specificity of 93% (95% CI = 80% to 95%), positive likelihood ratio of 5.9, and negative likelihood ratio of 0.6 for predicting in-hospital mortality. Conclusions:, Early, noninvasive measurement of the cardiac index in critically ill severe sepsis and septic shock patients can be performed in the ED for those who meet criteria for EGDT. There appears to be an association between an initial lower cardiac index as measured noninvasively and in-hospital mortality.

Implementing Early Goal-directed Therapy in the Emergency Setting: The Challenges and Experiences of Translating Research Innovations into Clinical Reality in Academic and Community Settings

ACADEMIC EMERGENCY MEDICINE, Issue 11 2007
Alan E. Jones MD
Research knowledge translation into clinical practice pathways is a complex process that is often time-consuming and resource-intensive. Recent evidence suggests that the use of early goal-directed therapy (EGDT) in the emergency department care of patients with severe sepsis and septic shock results in a substantial mortality benefit; however, EGDT is a time- and resource-intensive intervention. The feasibility with which institutions may translate EGDT from a research protocol into routine clinical care, among settings with varying resources, staff, and training, is largely unknown. The authors report the individual experiences of EGDT protocol development, as well as preimplementation and postimplementation experiences, at three institutions with different emergency department, intensive care unit, and hospital organization schemes.

The Utility of a Quality Improvement Bundle in Bridging the Gap between Research and Standard Care in the Management of Severe Sepsis and Septic Shock in the Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 11 2007
H. Bryant Nguyen MD
The research in the management of severe sepsis and septic shock has resulted in a number of therapeutic strategies with significant survival benefits. These results also emphasize the primary importance of early hemodynamic resuscitation, or early goal-directed therapy (EGDT), and place the emergency physician in the center of the multidisciplinary team caring for patients with this disease. However, in a busy emergency department, the translation of research into clinical practice is far from ideal. While the benefits are significant, the successful implementation of EGDT is filled with challenges and obstacles. In this article, we will discuss the steps taken at our institution to create, implement, measure, and improve on a six-hour severe sepsis and septic shock treatment bundle incorporating EGDT in the emergency department setting, resulting in significant mortality benefit.
