It has been reported that exhaled carbon monoxide (CO) concentrations and arterial carboxyhemoglobin (CO-Hb) concentration in blood may be increased in critically ill patients. However, there was no study that examined correlation among amount of CO in exhaled air, CO-Hb concentrations in erythrocytes, and bilirubin IX alpha (BR) in serum, i.e., the three major indexes of heme catabolism, within the same subject. Here, we examined CO concentrations in exhaled air, CO-Hb concentrations in arterial blood, and BR levels in serum in 29 critically ill patients. Measurements of exhaled CO, arterial CO-Hb, and serum total BR have been done in the intensive care unit. As control, exhaled CO concentration was also measured in eight healthy volunteers. A median exhaled CO concentration was significantly higher in critically ill patients compared with control. There was significant correlation between CO and CO-Hb and CO and total BR level. We also found CO concentrations correlated with indirect BR but not direct BR. Multivariate linear regression analysis for amount of exhaled CO concentrations also showed significant correlation with CO-Hb and total BR, despite the fact that respiratory variables of study subjects were markedly heterogeneous. We found no correlation among exhaled CO, patients' severity, and degree of inflammation, but we found a strong trend of a higher exhaled CO concentration in survivors than in nonsurvivors. These findings suggest there is an increased heme breakdown in critically ill patients and that exhaled CO concentration, arterial CO-Hb, and serum total BR concentrations may be useful markers in critically ill conditions.

Introduction The choice of invasive systemic haemodynamic monitoring in critically ill patients remains controversial as no multicentre comparative clinical data exist. Accordingly, we sought to study and compare the features and outcomes of patients who receive haemodynamic monitoring with either the pulmonary artery catheter (PAC) or pulse contour cardiac output (PiCCO) technology.
Methods We conducted a prospective multicentre, multinational epidemiological study in a cohort of 331 critically ill patients who received haemodynamic monitoring by PAC or PiCCO according to physician preference in intensive care units (ICUs) of eight hospitals in four countries. We collected data on haemodynamics, demographic features, daily fluid balance, mechanical ventilation days, ICU days, hospital days, and hospital mortality. We statistically compared the two techniques.
Results Three hundred and forty-two catheters ( PiCCO 192 and PAC 150) were inserted in 331 patients. On direct comparison, patients with PAC were older ( 68 versus 64 years of age; p = 0.0037), were given inotropic drugs more frequently 37.3% versus 13%; p < 0.0001), and had a lower cardiac index (2.6 versus 3.2 litres/ minute per square meter; p < 0.0001). Mean daily fluid balance was significantly greater during PiCCO monitoring (+ 659 versus + 350 ml/day; p = 0.017) and mechanical ventilation-free days were fewer ( 12 for PiCCO versus 21 for PAC; p = 0.045). However, after multiple regression analysis, we found no significant effect of monitoring technique on mean daily fluid balance, mechanical ventilation-free days, ICU-free days, or hospital mortality. A secondary multiple logistic regression analysis for hospital mortality which included mean daily fluid balance showed that positive fluid balance was a significant predictor of hospital mortality ( odds ratio = 1.0002 for each ml/day; p = 0.0073).
Conclusion On direct comparison, the use of PiCCO was associated with a greater positive fluid balance and fewer ventilator-free days. After correction for confounding factors, the choice of monitoring did not influence major outcomes, whereas a positive fluid balance was a significant independent predictor of outcome. Future studies may best be targeted at understanding the effect of pursuing different fluid balance regimens rather than monitoring techniques per se.

We investigated whether perioperative extensive epidural block (C3-L) affects postoperative immune response in patients undergoing radical esophagectomy. Patients undergoing radical esophagectomy were randomly assigned to either general anesthesia with continuous epidural infusion via 2 epidural catheters that was continued for postoperative analgesia (group E, n = 15) or intraoperative general anesthesia and postoperative IV morphine analgesia (group G, n = 15). Plasma levels of stress hormones, cytokines, C-reactive protein (CRP), leukocyte counts, and distribution of lymphocyte subsets were assessed before and after surgery and on postoperative days (PODs) 1 and 3. In comparison with group E, significant increases in plasma epinephrine level at the end of surgery (P < 0.05) and norepinephrine level at the end of surgery (P < 0.01) and on POD1 (P < 0.01) and POD3 (P < 0.01) and significant decrease in cluster of differentiation (CD4/CD8 ratio) at the end of surgery (P < 0.05) were observed in group G. However, there were no significant differences in other variables between groups. In both groups, plasma cortisol, adrenocorticotropic hormone, interleukin (IL)-1 beta, IL-6, IL-10, and CRP levels were increased after surgery (each group P < 0.01) and IL-1 beta, IL-6, IL-10, and CRP were still increased on POD1 and POD3 (each change, each group P < 0.01). Leukocyte counts were increased on PODI (each group P < 0.05) and POD3 (each group P < 0.01). The proportion of lymphocytes decreased from the end of surgery to POD3 (each group P < 0.01). The proportion of B cells was increased on POD1 (each group P < 0.01); that of natural killer cells was decreased at PODI and POD3 (each group P < 0.01). We conclude that tissue damage and inflammation apparently overcome the effects of extensive epidural block on stress response and immune function in radical esophagectomy.

Objective. Several different severity scoring systems specific to acute renal failure have been proposed. However, most validation studies of these scoring systems were conducted in a single center or in a small number of centers, often the same ones used for their development. Therefore, it is not known whether such severity scoring systems may be widely applied.
Design: Prospective clinical investigation.
Setting: Intensive care units.
Patients: One thousand seven hundred and forty-two intensive care unit patients with acute renal failure who were either treated with renal replacement therapy or fulfilled predefined criteria.
Interventions: Demographic and clinical information and outcomes were measured.
Measurements and Main Results. Scores for four acute renal failure-specific scoring systems and two general scoring systems (Simplified Acute Physiology Score II and Sequential Organ Failure Assessment) were calculated, and their discrimination and calibration were tested with receiver operating characteristic curves and Hosmer-Lemeshow goodness-of fit-tests. For the receiver operating characteristic curves, blood lactate levels were also used as a reference. All scores had an area under the receiver operating characteristic curve < 0.7 (Mehta 0.670, Liano 0.698, Chertow 0.610, Paganini 0.643, Simplified Acute Physiology Score II 0.645, Sequential Organ Failure Assessment 0.675, lactate 0.639). For scores that can calculate predicted mortality, the Hosmer-Lemeshow goodness-of-fit test showed poor calibration.
Conclusions: None of the scoring systems tested had a high level of discrimination or calibration to predict mortality for patients with acute renal failure when tested in a broad cohort of patients from multiple countries. A large, multiple-center database might be needed to improve the discrimination and calibration of acute renal failure scoring system.

Context Although acute renal failure (ARF) is believed to be common in the setting of critical illness and is associated with a high risk of death, little is known about its epidemiology and outcome or how these vary in different regions of the world.
Objectives To determine the period prevalence of ARF in intensive care unit (ICU) patients in multiple countries; to characterize differences in etiology illness severity, and clinical practice; and to determine the impact of these differences on patient outcomes.
Design, Setting, and Patients Prospective observational study of ICU patients who either were treated with renal replacement therapy (RRT) or fulfilled at least 1 of the predefined criteria for ARF from September 2000 to December 2001 at 54 hospitals in 23 countries.
Main Outcome Measures Occurrence of ARF, factors contributing to etiology, illness severity, treatment, need for renal support after hospital discharge, and hospital mortality.
Results Of 29 269 critically ill patients admitted during the study period, 1738 (5.7%; 95% confidence interval [CI], 5.5%-6.0%) had ARF during their ICU stay, including 1260 who were treated with RRT. The most common contributing factor to ARF was septic shock (47.5%; 95% Cl, 45.2%-49.5%). Approximately 30% of patients had preadmission renal dysfunction. Overall hospital mortality was 60.3% (95% Cl, 58.0%-62.6%). Dialysis dependence at hospital discharge was 13.8% (95% Cl, 11.2%-16.3%) for survivors. Independent risk factors for hospital mortality included use of vasopressors (odds ratio [OR], 1.95; 95% Cl, 1.50-2.55; P<.001), mechanical ventilation (OR, 2.11; 95% Cl, 1.58-2.82; P<.001), septic shock (OR, 1.36; 95% Cl, 1.03-1.79; P=.03), cardiogenic shock (OR, 1.41; 95% Cl, 1.05-1.90; P=.02), and hepatorenal syndrome (OR, 1.87; 95% Cl, 1.07-3.28; P=.03).
Conclusion In this multinational study; the period prevalence of ARF requiring RRT in the ICU was between 5% and 6% and was associated with a high hospital mortality rate.

A quantitative analysis of the acidosis of cardiac arrest: a prospective observational study

CRITICAL CARE 9 ( 4 ) R357 - R362 2005年8月

記述言語：英語出版者・発行元：BIOMED CENTRAL LTD

Introduction Metabolic acidosis is common in patients with cardiac arrest and is conventionally considered to be essentially due to hyperlactatemia. However, hyperlactatemia alone fails to explain the cause of metabolic acidosis. Recently, the Stewart Figge methodology has been found to be useful in explaining and quantifying acid - base changes in various clinical situations. This novel quantitative methodology might also provide useful insight into the factors responsible for the acidosis of cardiac arrest. We proposed that hyperlactatemia is not the sole cause of cardiac arrest acidosis and that other factors participate significantly in its development.
Methods One hundred and five patients with out-of-hospital cardiac arrest and 28 patients with minor injuries ( comparison group) who were admitted to the Emergency Department of a tertiary hospital in Tokyo were prospectively included in this study. Serum sodium, potassium, ionized calcium, magnesium, chloride, lactate, albumin, phosphate and blood gases were measured as soon as feasible upon arrival to the emergency department and were later analyzed using the Stewart - Figge methodology.
Results Patients with cardiac arrest had a severe metabolic acidosis ( standard base excess - 19.1 versus - 1.5; P < 0.0001) compared with the control patients. They were also hyperkalemic, hypochloremic, hyperlactatemic and hyperphosphatemic. Anion gap and strong ion gap were also higher in cardiac arrest patients. With the comparison group as a reference, lactate was found to be the strongest determinant of acidosis (- 11.8 meq/ l), followed by strong ion gap (- 7.3 meq/ l) and phosphate (- 2.9 meq/ l). This metabolic acidosis was attenuated by the alkalinizing effect of hypochloremia (+ 4.6 meq/ l), hyperkalemia (+ 3.6 meq/ l) and hypoalbuminemia (+ 3.5 meq/ l).
Conclusion The cause of metabolic acidosis in patients with out-of-hospital cardiac arrest is complex and is not due to hyperlactatemia alone. Furthermore, compensating changes occur spontaneously, attenuating its severity.
