Incidence, treatment, and outcome of severe sepsis in ICU-treated adults in Finland: the Finnsepsis study.

OBJECTIVE: To determine the incidence and outcome of severe sepsis in the adult Finnish population and to evaluate how treatment guidelines in severe sepsis are applied in clinical practice. STUDY DESIGN: A prospective study in 24 closed multidisciplinary ICUs in 21 hospitals (4 university and 17 tertiary hospitals) in Finland. PATIENTS: All 4,500 consecutive ICU admission episodes were screened for severe sepsis during a 4-month period (1 November 2004 - 28 February 2005). The referral population was 3,743,225. RESULTS: The severe sepsis criteria were fulfilled in 470 patients, who had 472 septic episodes. The incidence of severe sepsis in the ICUs in Finland was 0.38/1000 in the adult population (95% confidence interval 0.34-0.41). The mean ICU length of stay was 8.2+/-8.1 days. ICU, hospital, and 1-year mortality rates were 15.5%, 28.3%, and 40.9%, respectively. Respiratory failure requiring ventilation support was the most common organ failure (86.2%); septic shock was present in 77% and acute renal failure in 20.6% of cases. Activated protein C was given to only 15 of the 55 patients with indication (27%) and low-dose corticosteroids to 150 of 366 (41%) patients with septic shock. CONCLUSIONS: This prospective study found the incidence of ICU-treated severe sepsis in Finland to be 0.38 per 1,000 of the population. The ICU and hospital mortalities were also lower than earlier reported in United States or Australia. Evidence-based sepsis therapies were not used as often as recommended.

Mixed venous oxygen saturation cannot be estimated by central venous oxygen saturation in septic shock.

OBJECTIVE: Central venous oxygen saturation (ScvO2) in initial resuscitation is included in the Surviving Sepsis Campaign guidelines. ScvO2 monitoring has also been suggested to be comparable to mixed venous oxygen saturation (SvO2) for clinical purposes. The aim of our study was to assess the correlation and agreement of ScvO2 and SvO2 and compare ScvO2-SvO2 difference to lactate, oxygen-derived and hemodynamic parameters in early septic shock in ICU after initial resuscitation. DESIGN AND SETTING: Prospective clinical study with 16 patients with septic shock at two university hospital ICUs. A dose of norepinephrine over 0.1 microg/kg/min was required for inclusion. MEASUREMENTS AND RESULTS: Five paired ScvO2 and SvO2 samples at 6-h intervals, altogether 72 samples, were collected during 24 h. The mean SvO2 was below the mean ScvO2 at all time points. Bias of difference was 4.2% and 95% limits of agreement ranged from -8.1% to 16.5%. The difference correlated significantly to CI and DO2. CONCLUSIONS: The difference between paired ScvO2 and SvO2 varies highly. Therefore, SvO2 may not be estimated on the basis of ScvO2 in treatment of septic shock after resuscitation period in ICU.

Association of carotid intima-media thickness with angiographic severity and extent of coronary artery disease.

The present study examined the association between carotid intima-media thickness (IMT) and severity and extent of coronary artery disease (CAD). B-mode ultrasound and quantitative coronary angiography were used to assess carotid and coronary artery atherosclerosis in 108 patients with known or suspected CAD who had been referred for cardiac catheterization. Maximum and mean IMT values of carotid arteries were measured and expressed as mean aggregate values. To evaluate anatomic severity and extent of CAD, several quantitative coronary angiographically derived parameters were incorporated into indexes. These quantitative coronary angiographic measurements reflected CAD severity, extent, and overall "atheroma burden" and were calculated for the entire coronary tree and separately for different coronary segments (i.e., left main, proximal, mid, and distal segments). Maximum and mean IMT values were significantly correlated with CAD severity (p = 0.004 and 0.005, respectively), extent (p = 0.022 and 0.016, respectively), and atheroma burden (p = 0.008 for the 2 values). Further, carotid IMT was correlated with quantitative angiographic indexes for mid and distal segments but not with the proximal segments of coronary vessels. In conclusion, our study shows an association between carotid IMT and severity and extent of CAD as assessed by quantitative coronary angiography. Carotid IMT seems to be a weaker predictor of coronary atherosclerosis in the proximal parts of the coronary tree than in the mid and distal parts.

Hemodynamic variables related to outcome in septic shock.

OBJECTIVE: To assess the impact of hemodynamic variables on the outcome of critically ill patients in septic shock and to identify the optimal threshold values related to outcome with special reference to continuously monitored mean arterial pressure (MAP) and mixed venous oxygen saturation (SvO2). DESIGN AND SETTING: Retrospective cohort study in a university hospital intensive care unit (ICU). PATIENTS: All consecutive 111 patients with septic shock treated in our ICU between 1 Jan. 1999 and 30 Jan. 2002. MEASUREMENTS AND RESULTS: The data on the hemodynamic and respiratory monitoring and circulation-related laboratory tests over the first 48 h of treatment in the ICU were collected from the clinical data management system. Data from 6 h and 48 h were analyzed separately. The 30-day mortality rate was 33% (36 of 111). Univariate analysis and forward stepwise logistic regression analysis were performed using the 30-day mortality as the primary endpoint. Mean MAP and lactate on arrival during 6 h, while mean MAP, the area of SvO2 under 70%, and mean CVP during 48 h were independently associated with mortality. MAP level of 65 mmHg and SvO2 of 70% had the highest areas under receiver characteristics curves. CONCLUSIONS: MAP, SvO2, CVP, and initial lactate were independently associated with mortality in septic shock, with threshold values supporting those published in recent guidelines.
