Background. Achieving hemodynamic stabilization does not prevent progressive tissue hypoperfusion and organ dysfunction during resuscitation of septic shock patients. Many indicators have been proposed to judge the optimization of oxygen delivery to meet tissue oxygen consumption. Methods. A prospective observational study was conducted to evaluate and validate combining CO2 gap and oxygen-derived variables with lactate clearance during early hours of resuscitation of adults presenting with septic shock. Results. Our study included 456 adults with a mean age of 63.2 ± 6.9 years, with 71.9% being males. Respiratory and urinary infections were the origin of about 75% of sepsis. Mortality occurred in 164 (35.9%) patients. The APACHE II score was 18.2 ± 3.7 versus 34.3 ± 6.8 ( p < 0.001 ), the initial SOFA score was 5.8 ± 3.1 versus 7.3 ± 1.4 ( p = 0.001 ), while the SOFA score after 48 hours was 4.2 ± 1.8 versus 9.4 ± 3.1 ( p < 0.001 ) in the survivors and nonsurvivors, respectively. Hospital mortality was independently predicted by hyperlactatemia (OR: 2.47; 95% CI: 1.63–6.82, p = 0.004 ), PvaCO2 gap (OR: 2.62; 95% CI: 1.28–6.74, p = 0.026 ), PvaCO2/CavO2 ratio (OR: 2.16; 95% CI: 1.49–5.74, p = 0.006 ), and increased SOFA score after 48 hours of admission (OR: 1.86; 95% CI: 1.36–8.13, p = 0.02 ). A blood lactate cutoff of 40 mg/dl at the 6th hour of resuscitation (T6) had a 92.7% sensitivity and 75.3% specificity for predicting hospital mortality (AUROC = 0.902) with 81.6% accuracy. Combining the lactate cutoff of 40 mg/dl and PvaCO2/CavO2 ratio cutoff of 1.4 increased the specificity to 93.2% with a sensitivity of 75.6% in predicting mortality and with 86.8% accuracy. Combining the lactate cutoff of 40 mg/dl and PvaCO2 gap of 6 mmHg increased the sensitivity to 93% and increased the specificity to 98% in predicting mortality with 91% accuracy. Conclusion. Combining the carbon dioxide gap and arteriovenous oxygen difference with lactate clearance during early hours of resuscitation of septic shock patients helps to predict hospital mortality more accurately.

Background Extracorporeal cytokine adsorption is an option in septic shock as an additional measure to treat a pathological immune response. Purpose of this study was to investigate the effects of extracorporeal cytokine adsorption on hemodynamic parameters in patients with acute kidney injury (AKI) on continuous renal replacement therapy (CRRT) and septic shock after cardiac surgery. Methods In this retrospective study, a total of 98 patients were evaluated. Hemoadsorption was performed by the CytoSorb® adsorber. In all patients cytokine adsorption was applied for at least 15 hours and at least one adsorber was used per patient. To compare cumulative inotrope need in order to maintain a mean arterial pressure (MAP) of ≥ 65 mmHg, we applied vasoactive score (VAS) for each patient before and after cytokine adsorption. A paired t-test has been performed to determine statistical significance. Results Before cytokine adsorption the mean VAS was 56.7 points. This was statistically significant decreased after cytokine adsorption (27.7 points, p< 0.0001). Before cytokine adsorption, the mean noradrenalin dose to reach a MAP of ≥ 65 mmHg was 0.49 μg/kg bw/min, the mean adrenalin dose was 0.12 μg/kg bw/min. After cytokine adsorption, significantly reduced catecholamine doses were necessary to maintain a MAP of ≥ 65 mmHg (0.24 μg/kg bw/min noradrenalin; p< 0.0001 and 0.07 μg/kg bw/min adrenalin; p < 0.0001). Moreover, there was a significant reduction of serum lactate levels after treatment (p< 0.0001). The mean SOFA-score for these patients with septic shock and AKI before cytokine adsorption was 16.7 points, the mean APACHE II-score was 30.2 points. The mean predicted in-hospital mortality rate based on this SOFA-score of 16.7 points was 77,0%, respectively 73,0% on APACHE II-score, while the all-cause in-hospital mortality rate of the patients in this study was 59.2%. Conclusion In patients with septic shock and AKI undergoing cardiac surgery, extracorporeal cytokine adsorption could significantly lower the need for postoperative inotropes. Additionally, observed versus SOFA- and APACHE II-score predicted in-hospital mortality rate was decreased.

Predict Hospital Mortality

The ability to accurately adjust for the severity of illness in outcome studies of critically ill patients is essential. Previous studies have showed that Sequential Organ Failure Assessment (SOFA) score and Acute Physiology and Chronic Health Evaluation (APACHE) II score can predict hospital mortality of critically ill patients. The effects of combining these two scores to predict hospital mortality of critically ill patients has not been evaluated. This cohort study evaluated the performance of combining the APACHE II score with SOFA score in predicting hospital mortality of critically ill patients. A total of 1,311 consecutive adult patients admitted to a tertiary 22-bed multidisciplinary intensive care unit (ICU) in Western Australia were considered. The APACHE II, Admission SOFA, Delta SOFA and maximum SOFA score were all related to hospital survival in the univariate analyses. Combining Max SOFA (area under receiver operating characteristic curve 0.875 vs. 0.858, P=0.014; Nagelkerke R2: 0.411 vs. 0.371; Brier Score: 0.086 vs. 0.090) or Delta SOFA score (area under receiver operating characteristic curve 0.874 vs. 0.858, P=0.003; Nagelkerke R2: 0.412 vs. 0.371; Brier Score: 0.086 vs. 0.090) with the APACHE II score improved the discrimination and overall performance of the predictions when compared with using the APACHE II score alone, especially in the emergency ICU admissions. Combining Max SOFA or Delta SOFA score with the APACHE II score may improve the accuracy of risk adjustment in outcome studies of critically ill patients.

Introduction: In 2016, a new definition of sepsis and septic shock was adopted. Some studies based on the general population demonstrated that the Sequential Organ Failure Assessment (SOFA) score is more accurate than the systemic inflammatory response syndrome (SIRS) criteria to predict hospital mortality of infected patients requiring intensive care. Patients and Method: We have analyzed all the records of patients with cancer admitted for a suspected infection between January 1, 2013, and December 31, 2016, in our oncological intensive care unit (ICU). Sequential Organ Failure Assessment score and quick SOFA (qSOFA) score as well as SIRS criteria were calculated. We analyzed the accuracy of each score to predict hospital mortality in the setting of the new and old definitions of septic shock. Results: Our study includes 241 patients with a solid tumor and 112 with a hematological malignancy. The hospital mortality rate is 37% (68% in patients with septic shock according to the new definition and 60% according to old definition) between 2013 and 2016. To predict hospital mortality, the SOFA score has an area under the receiver operating characteristic curve of 0.74 (95% confidence interval [CI], 0.68-0.79), the qSOFA of 0.65 (95% CI, 0.59-0.70), and the SIRS criteria of 0.58 (95% CI, 0.52-0.63). In multivariate analysis, a higher SOFA score or a higher qSOFA score indicates poor prognosis: odds ratio (OR) per 1-point increase by 1.28 (95% CI, 1.18-1.39) and 1.48 (95% CI, 1.04-2.11), respectively. Complete remission is a good prognostic factor for hospital mortality: OR 0.39 (95% CI, 0.22-0.67). Conclusion: The new definition of sepsis and septic shock is applicable in an ICU oncological population with the same reliability as in the general population. The SOFA score is more accurate than qSOFA and SIRS criteria to predict hospital mortality.

To determine the relation between the proposed ACCP/SCCM Consensus Conference classification of sepsis and hospital outcomes, we conducted a single-center, prospective observational study at Barnes Hospital, St. Louis, MO, an academic tertiary care hospital. A total of 324 consecutive patients admitted to the medical intensive care unit (ICU) were studied for prospective patient surveillance and data collection. The main outcome measures were the number of acquired organ system derangements and hospital mortality. Fifty-seven (17.6%) patients died during the study period. The proposed classifications of sepsis (e.g., systemic inflammatory response syndrome [SIRS], sepsis, severe sepsis, septic shock) correlated with hospital mortality ( r = 0.330; p < 0.001) and development of an Organ System Failure Index (OSFI) of 3 or greater ( r = 0.426; p < 0.001). Independent determinants of hospital mortality for this patient cohort ( p < 0.05) were development of an OSFI of 3 or greater (adjusted odds ratio [AOR], 13.9; 95% confidence interval [CI], 6.4–30.2; p < 0.001); presence of severe sepsis or septic shock (AOR, 2.6; 95% CI, 1.2–5.6; p = 0.002), and an APACHE II score ≥ of 18 or greater (AOR, 2.4; 95% CI, 1.0–5.8; p = 0.045). Intra-abdominal infection (AOR, 19.1; 95% CI, 1.6–230.1; p = 0.011), an APACHE II score ≥ of 18 or greater (AOR, 8.9; 95% CI, 4.2–18.6; p < 0.001), and presence of severe sepsis or septic shock (AOR, 2.9; 95% CI, 1.5–5.4; p = 0.001) were independently associated with development of an OSFI of 3 or greater. These data confirm that acquired multiorgan dysfunction is the most important predictor of mortality among medical ICU patients. In addition, they identify the proposed ACCP/SCCM Consensus Conference classification of sepsis as an additional independent determinant of both hospital mortality and multiorgan dysfunction.

Background: Little data exists guiding clinicians on how or when to initiate and discontinue the second vasoactive agent in the setting of septic shock refractory to norepinephrine monotherapy. Methods: This retrospective cohort study evaluated patients with a primary diagnosis of septic shock admitted to the intensive care unit receiving norepinephrine in addition to concomitant vasopressors. The primary endpoint was the incidence of all-cause in-hospital mortality when adding adjunctive vasopressors to norepinephrine either before the dose reached 2 mcg/kg/min (early adjunctive vasopressor) or after (late adjunctive vasopressor). Secondary endpoints included the incidence of clinically significant hypotension when discontinuing norepinephrine before or after vasopressin in the same population. Results: Forty-six patients were included (early adjunctive vasopressor [n=36]; late adjunctive vasopressor [n=10]), with a median age of 69 years and APACHE II score of 27. Fewer patients in the early adjunctive vasopressor cohort had malignancy prior to admission (16.7% vs. 60%, p=0.0117), however, more patients were managed in the surgical ICU (44.4% vs. 0%, p=0.0202) with intra-abdominal infection (33.3% vs. 0%, p=0.0439). The primary endpoint of all-cause in-hospital mortality was not statistically different between the early and late adjunctive vasopressor groups (75% vs. 90%, respectively, p=0.4203). Longer ICU and hospital length of stay in the early adjunctive vasopressor cohort was observed (9 days vs 3 days, p=0.0061; 11 days vs 3 days, p=0.0026, respectively). Twenty-two patients were included in analysis of vasopressor discontinuation sequence with no significant differences in mortality, incidence of hypotension, or ICU/hospital length of stay. Conclusion: Among patients with septic shock on multiple vasopressors, addition of adjunctive vasopressor before reaching a norepinephrine dose of 2 mcg/kg/min was associated with longer in-hospital and ICU survival but exhibited no difference in overall mortality. Discontinuation of vasopressin before norepinephrine led to longer total vasopressor duration without a difference in rates of hypotension. Future prospective studies are warranted.

Abstract Background: Doppler snuffbox resistive index (SBRI) can be a accurate parameter at the bedside to evaluate the status of peripheral vascular. We evaluated whether SBRI could relate to tissue hypoperfusion and could predict lactate clearance in septic patients. Methods: We conducted a prospective observational study in a tertiary general and teaching hospital in China.From July 2019 to Decemeber 2019,all consecutive adult patients with septic shock who required ICU admission were included. At the same time,postoperative patients were studied as a control group.we recorded the hemodynamic parameters including SBRI and PI which were measured simultaneously after involved . Results: We evaluated 44 patients with septic shock in study group and 20 stable postoperative patients in control group. Patients with septic shock had higher SOFA scores,PCT, CI and lactate than patients in control group.The SBRI was correlated with PI and lactate. The CI was not correlated with lactate in all patients.Based on Lactate clearance in first 6 hours, the septic shock patients were divided into the Lactate clearance ≥20% or the Lactate clearance <20% group.CI is no significal difference between two groups.SBRI of the Lactate clearance <20% group is higher than Lactate clearance≥20% group and control group.PI of the Lactate clearance <20% group is lower than Lactate clearance≥20% group and control group.The cutoff of the SBRI value was ≥1.09 for predicting 6h-lactate clearance after resuscitation, resulting in a sensitivity of 68.8% and a specificity of 85.7%. The cutoff of the PI value was ≤0.99 for predicting 6h-lactate clearance after resuscitation, resulting in a sensitivity of 64.3% and a specificity of 81.2%. The SBRI was significantly better than the PI for predicting 6h-lactate clearance after resuscitation. Conclusions: SBRI is correlated with tissue perfusion parameters in critical ill patients. Abnormal SBRI was better than PI in suggesting disorder of lactate clearance of septic patients. SBRI is a better indicator of abnormal tissue perfusion than CI. Further investigations are required to determine whether the correction of abnormal SBRI and PI may improve success rate of resuscitation of septic shock.

Objective: Predicting prognosis is a complex process, particularly in patients with severe sepsis or septic shock. This study aimed to determine the relationship between the Sequential Organ Failure Assessment (SOFA) scores for individual organs during the first week of admission and the in-hospital mortality in patients with sepsis. Methods: This study was a post hoc evaluation of the Japan Septic Disseminated Intravascular Coagulation study and included patients admitted to 42 intensive care units in Japan for severe sepsis or septic shock, between January 2011 and December 2013. We assessed the relationship between the organ and total SOFA scores on days 1, 3, and 7 following admission and the in-hospital mortality using logistic regression analysis. Results: We evaluated 2732 patients and found the in-hospital mortality rate was 29.1%. The mean age of the patients (standard deviation) was 70.5 (14.1) years, and the major primary site of infection was the abdomen (33.6%). The central nervous system (CNS) SOFA score exhibited the strongest relationship with mortality on days 1 (adjusted odds ratio [aOR]: 1.49, 95% confidence interval [CI]: 1.40-1.59), 3 (aOR: 1.75, 95% CI: 1.62-1.89), and 7 (aOR: 1.93, 95% CI: 1.77-2.10). The coagulation SOFA scores showed a weak correlation with mortality on day 1, but a strong correlation with mortality on day 7 (aOR: 2.04, 95% CI: 1.87-2.24). Conclusions: The CNS SOFA scores were associated with mortality in patients with severe sepsis on days 1, 3, and 7 following hospitalization. The coagulation SOFA score was associated with mortality on day 7. In clinical situations, the CNS SOFA scores during the acute phase and the CNS SOFA and coagulation SOFA scores during the subsequent phases should be evaluated in order to determine patient prognosis.

AbstractLactate clearance is affected by hepatic function. However, it is unclear whether the association between hepatic dysfunction and lactate clearance can act as a prognostic marker of clinical outcomes in patients with septic shock. We aimed to evaluate the association between lactate clearance and mortality in two cohorts of septic shock patient who had hepatic dysfunction based on their total serum bilirubin levels (TBIL). Lactate clearance at 24 h after the onset of septic shock was analyzed using two cohorts, sub-categorized into two groups based on TBIL: < 2 mg/dL and ≥ 2 mg/dL. In the derivation cohort, lactate clearance was lower in non-survivors than in survivors with TBIL ≥ 2 mg/dL, while there was no significant difference in lactate clearance between non-survivors and survivors with TBIL < 2 mg/dL. Multivariate logistic regression analysis revealed that increased lactate clearance was significantly associated with decreased 28-day mortality in the TBIL ≥ 2 mg/dL group (10% lactate clearance, adjusted odds ratio [OR]: 0.88, 95% confidence interval (CI): 0.80–0.97, P = 0.0075), Creatinine level ≥ 2 mg/dL group (adjusted OR: 0.88, 95% CI: 0.81–0.95, P = 0.00069) and APACHE II score ≥ 35 group (adjusted OR: 0.93, 95% CI: 0.87–0.98, P = 0.013). In the validation cohort, lactate clearance was lower in non-survivors than in survivors with TBIL ≥ 2 mg/dL, while no significant difference in lactate clearance was observed between non-survivors and survivors with TBIL < 2 mg/dL. Increased lactate clearance was significantly associated with decreased 28-day mortality in the TBIL ≥ 2 mg/dL group (10% lactate clearance, adjusted OR: 0.89, 95% CI: 0.83–0.96, P = 0.0038) and the association was just about significant in APACHE II score ≥ 35 group (adjusted OR: 0.86, 95% CI: 0.74–1.00, P = 0.051). In conclusion, increased lactate clearance in septic shock patients with hepatic dysfunction (TBIL ≥ 2 mg/dL) or high severity (APACHE II score ≥ 35) was associated with decreased 28-day mortality.

<b><i>Introduction:</i></b> Polymyxin B-immobilized fiber column direct hemoperfusion (PMX-DHP) is used for patients with septic shock, and the recommended hemoperfusion period is 2 h. However, it remains unclear whether the optimal duration is 2 h or longer. The purpose of this study was to compare the effects of PMX-DHP between conventional and longer duration of PMX-DHP. <b><i>Methods:</i></b> We retrospectively investigated 103 patients with sepsis who underwent PMX-DHP. The demographic data, routine biochemistry, microbiological data, and primary infection site were reviewed in the medical chart. The acute physiology and chronic health evaluation (APACHE) II score, sequential organ failure assessment (SOFA) score, heart rate, mean arterial pressure (MAP), vasoactive-inotropic score (VIS), and PaO<sub>2</sub>/FiO<sub>2</sub>, at baseline and day 3, were compared between the standard group (2 h of PMX-DHP) and the extended group (&#x3e;2 h of PMX-DHP). <b><i>Results:</i></b> Median MAP was significantly lower and median VIS was significantly higher in the extended group at baseline (<i>p</i> &#x3c; 0.05, 0.01, respectively) There were no significant differences in APACHE II score, SOFA score, and PaO<sub>2</sub>/FiO<sub>2</sub> at baseline between the 2 groups. The increase of MAP and the decrease in VIS from baseline to day 3 were significantly greater in the extended group (<i>p</i> &#x3c; 0.01, respectively). In the extended group, increase in PaO<sub>2</sub>/FiO<sub>2</sub> was significantly larger in the patients who underwent ≥8 h duration than that in patients who underwent &#x3c;8 h duration (<i>p</i> &#x3c; 0.01). The ventilator-free days, the incidence of continuous renal replacement therapy, and the 28-day mortality were not different between the groups. <b><i>Discussion/Conclusions:</i></b> Longer duration of PMX-DHP was associated with the improved MAP and decreased volume of vasoactive-inotropic agents compared with the conventional duration. Eight and longer hours duration of PMX-DHP was associated with the improvement in the pulmonary oxygenation. Further studies are needed to confirm the efficacy of longer duration of PMX-DHP in patients with septic shock.

Objective To compare outcomes between elderly (≥65 years old) and non-elderly (<65 years old) resuscitated severe sepsis and septic shock patients and determine predictors of death among elderly patients.Methods Retrospective cohort study including 848 severe sepsis and septic shock patients admitted to the intensive care unit between January 2006 and March 2012.Results Elderly patients accounted for 62.6% (531/848) and non-elderly patients for 37.4% (317/848). Elderly patients had a higher APACHE II score [22 (18-28)versus 19 (15-24); p<0.001], compared to non-elderly patients, although the number of organ dysfunctions did not differ between the groups. No significant differences were found in 28-day and in-hospital mortality rates between elderly and non-elderly patients. The length of hospital stay was higher in elderly compared to non-elderly patients admitted with severe sepsis and septic shock [18 (10-41)versus 14 (8-29) days, respectively; p=0.0001]. Predictors of death among elderly patients included age, site of diagnosis, APACHE II score, need for mechanical ventilation and vasopressors.Conclusion In this study population early resuscitation of elderly patients was not associated with increased in-hospital mortality. Prospective studies addressing the long-term impact on functional status and quality of life are necessary.
