Effect of early bundle therapy on prognosis of patients with sepsis and septic shock / 中华急诊医学杂志

Objective To observe the effect of early bundle therapy on prognosis of patients with sepsis/septic shock and analyze the risk factors for death.Methods A retrospective cohort study was conducted to select patients with sepsis/septic shock at the Second Soochow University Hospital betweenJanuary 1,2016,and December 31,2016.Data pertaining to demographic variables,compliance rate of bundle therapy,and incidence of organ failure were collected.Patients were categorized into the nonsurvivor or survivor groups based on 28-day mortality.Logistic regression analysis was used to identify risk factors for 28-day mortality.Results Totally 118 sepsis/septic shock patients were included in the analysis;28-day mortality was 32.2％.Compared to the survivor group,patients in the non-survivor group were more likely to have chronic heart dysfunction and cerebrovascular disease,lower lactate clearance,lower 6-h compliance rate of bundle therapy and higher incidence of failure of one or ＞2 organs.Age,leukocyte,blood urea nitrogen,creatinine,brain natriuretic peptide,sequential organ failure score and acute physiological and chronic health scores Ⅱ on admission,and lactate after bundle therapy were higher than that of the survivor group.Logistical regression analysis showed that age ≥ 75 years [odds ratio (OR)1.012],6-h lactate clearance ＜30％ (OR=1.122),chronic heart failure (OR=1.741),failure of ＞2 organs (OR=1.769),and 6-h compliance rate of bundle therapy (OR=1.958) were independent risk factors for 28-day mortality.Conclusions Patients with sepsis/septic shock need early diagnosis and resuscitation to improve the compliance rate of bundle therapy and reduce the mortality.

Treatment of Severe Sepsis-Based on Surviving Sepsis Campaign Guideline / 대한내과학회지

Sepsis is a systemic, deleterious host response to infection. The term "severe sepsis" is used when sepsis is complicated by acute organ dysfunction, and "septic shock" as sepsis complicated by either hypotension that is refractory to fluid resuscitation or by hyperlactatemia. The number of cases with severe sepsis exceeds 750,000 per year in the United States and the mortality is now closer to 20 to 30% in these days. The principles of the initial management bundle are to provide sufficient hemodynamic resuscitation and early initiation of appropriate antibiotics to mitigate uncontrolled infection. Initial resuscitation requires the use of intravenous fluids and vasopressors. It is very important to achieve the target of initial resuscitation. The supportive cares in ICU are also significant such as blood component transfusion, glucose control, renal replacement therapy, deep vein thrombosis prophylaxis and stress ulcer prophylaxis. The goals of care and prognosis including end-of-life care should be discussed with patients and families as early as feasible.

Clinical studies of surviving sepsis bundles according to PiCCO on septic shock patients / 中华危重病急救医学

Objective To explore the effect of early goal-directed therapy (EGDT) according to pulse indicated continuous cardiac output (PiCCO) on septic shock patients.Methods Eighty-two septic shock patients in Subei People's Hospital of Jiangsu Province from January 2009 to December 2012 were enrolled and randomly divided into two groups using a random number table,standard surviving sepsis bundle group (n=40) and modified surviving sepsis bundles group (n =42).The patients received the standard EGDT bundles in standard surviving sepsis bundle group.PiCCO catheter was placed in modified surviving sepsis bundles group.Fluid resuscitation was guided by intrathoracic blood volume index (ITBVI) with the aim of 850-1 000 mL/m2.Dobutamine was used to improve the heart function according to left ventricular contractile index (dPmax) and stroke volume index (SVI).The mean arterial blood pressure (MAP) was maintained 65 mmHg (1 mmHg=0.133 kPa) or above with norepinephrine.Extra-vascular lung water was monitored for the titration of liquid and diuretics.The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,sequential organ failure assessment (SOFA) score,the number of patients needed vasopressor,serum procalcitonin (PCT),lactic acid and lactate extraction ratio,the amount of fluid resuscitation,duration of mechanical ventilation,duration of intensive care unit (ICU) stay,hospital mortality were recorded in both groups.Results After treatment,the APACHE Ⅱ score,SOFA score and the number of patients needed vasopressor were gradually reduced in both groups,and those in modified surviving sepsis bundle group were significantly lower than those of standard sepsis bundle group at 72 hours (APACHE Ⅱ score:13.1 ± 6.5 vs.20.9 ± 7.5,SOFA score:8.8 ± 4.3 vs.14.6 ± 4.9,the number of patients needed vasopressor:8 vs.17,all P＜0.05).Arterial blood lactate clearance rate was gradually increased after treatment in both groups.Lactate clearance rate in modified surviving sepsis bundle group was significantly higher than that of standard surviving sepsis bundle group [6 hours:(18.2 ± 8.3)％ vs.(10.8 ± 7.5)％,t=-6.036,P=0.001 ; 12 hours:(22.6 ± 7.3)％ vs.(12.4 ± 8.1)％,t=-4.536,P=0.001 ; 24 hours:(27.8 ± 5.6)％ vs.(16.4 ± 9.5)％,t=-5.882,P=0.000].The amount of fluid resuscitation within 6 hours in modified surviving sepsis bundle group increased significantly compared with standard surviving sepsis bundle group (mL:3 608 ± 715 vs.2 809 ± 795,t=-3.865,P=0.033).The amount of fluid resuscitation within 24,48 and 72 hours in modified surviving sepsis bundle group was significantly less than that of standard modified surviving sepsis bundle group with the nadir at 72 hours (mL:918 ± 351 vs.1 805 ± 420,t=5.907,P=0.037).Duration of mechanical ventilation (hours:98.4 ± 20.3 vs.143.3 ± 29.6,t=9.766,P=0.001) and ICU stay (days:7.1 ± 3.1 vs.9.5 ± 2.5,t=2.993,P=0.004) were significantly reduced in modified surviving sepsis bundle group compared with standard surviving sepsis bundle group.The hospital mortality in modified surviving sepsis bundle group was slightly lower than that in standard surviving sepsis bundle group [16.7％(7/42)比 17.5％(7/40),x2=0.010,P=0.920].Conclusions Modified surviving sepsis bundle treatment according PiCCO can reduce the severity of disease in patients with septic shock,can make more accurately guide fluid resuscitation,and can reduce lung water and duration of mechanical ventilation and ICU stay.It has great clinical significance.

Surviving Sepsis Campaign Bundles Adherence and Their Limits in Surgical Patients with Septic Shock in an ICU.

Aims: The Surviving Sepsis Campaign (SSC) guidelines aimed to reduce heterogeneity of conventional therapy and mortality. The present study was performed in septic shock to describe the adherence to the 2008 SSC guidelines, confounding factors, and limitations. Study Design: Prospective observational study. Place and Duration of Study: Clinic of Anaesthesiology, University Hospital Medical School, and Clinical Economics at the Institute of History, Philosophy and Ethics in Medicine, University of Ulm, between January 2008 and June 2009. Methodology: The adherence to 36 items of the 6-hour and 24-hour bundles of the 2008 SSC guidelines was investigated in 98 surgical patients with septic shock. Results: The adherence to the 36 items varied between 0% and 95%. Besides the categories “adherent“ and “nonadherent“, additional categories “partially adherent“, “notapplicable“ and “unknown“ were used. None of the single items alone was essential for survival. Patients with septic shock on admission (n=68) had significantly higher SOFA scores (degree of organ dysfunctions) compared to patients developing septic shock in the ICU (n = 30). Conclusion: As many confounders are limiting the adherence to complex guidelines, the complete adherence will hardly be possible in severe diseases such as septic shock. Our results suggest that efforts associated with early diagnosis and active encouragement outside the ICU are necessary to improve applicability and adherence to the SSC guidelines in patients with septic shock in order to reduce the time lag of diagnosis and treatment, which may be reached by focusing on few essential points.
