[Intrahepatic Hematoma and Pulmonary Embolism in a Young Woman with Oral Contraceptives Complicated by Type II Heparin Induced Thrombocytopenia Requiring ECMO-Therapy: a Case Report]. / Fulminante Lungenarterienembolie bei heparininduzierter Thrombozytopenie Typ II.

A 46-year-old woman on oral contraceptives developed an intrahepatic hematoma due to a benign hepatic tumor. As an incidental finding, a computed tomography showed a pulmonary embolism. Unfractionated heparin was given in a prophylactic dosing in an attempt to balance the risk of further intrahepatic bleeding with that of thrombosis. Ten days later, the patient developed a second pulmonary embolism along with acute right heart failure requiring cardiopulmonary resuscitation. As a sufficient circulation and oxygenation could not be reestablished, a veno-arterial extracorporeal membrane oxygenation (ECMO) was installed. An ELISA-Test, detecting PF4-Heparin associated antibodies, resulted in a positive result for a type II heparin induced thrombocytopenia even in the absence of thrombocytopenia. After hemodynamic and pulmonary stabilization, six days after ECMO-support the cannula was scheduled to be removed. On removal of the venous cannula the patient developed another massive pulmonary embolism with cardiac arrest which led to immediate reinstallation of va-ECMO. Under therapeutic anticoagulation using argatroban the ECMO support continued until the patient was on day 17 successfully weaned.

Elimination Rates of Electrolytes, Vitamins, and Trace Elements during Continuous Renal Replacement Therapy with Citrate Continuous Veno-Venous Hemodialysis: Influence of Filter Lifetime.

BACKGROUND/AIMS: During continuous renal replacement therapy, relevant losses of nutritional substrates, vitamins, and trace elements via the filter may occur. We investigated filter lifetime efficiency during a 72-h treatment period. METHODS: This prospective study included 40 patients undergoing citrate continuous veno-venous hemodialysis (CVVHD). The elimination rates were measured at 24, 48, and 72 h. To assess the influence of filter lifetime, we determined substrate loss every 24 h over a 72-h interval. RESULTS: Filter lifetime did not affect the loss of ionized calcium, inorganic phosphate, magnesium, zinc, folic acid, and vitamin B12. Nevertheless, we did observe clinically significant loss of ionized calcium and inorganic phosphate during CVVHD that required supplementation. CONCLUSIONS: CVVHD leads to significant loss of ionized calcium and inorganic phosphate that is independent of the filter lifetime.

[Risk factors for adverse reactions after protamine administration in adult patients undergoing cardiac surgery- a case report and literature review]. / Kasuistik mit Literaturübersicht - Protamingabe bei Patientin mit Fischeiweißallergie.

Protamine is a protein mainly used to reverse anticoagulant effects of heparin during cardiac or vascular surgery with extracorporeal circulation. Adverse events after protamine administration are rare but if they occur they can be catastrophic. Based on a case report with an elective cardiac surgery patient with known allergy to fish, we discuss the related events and risk factors for an adverse reaction after protamine. The patient management and its outcome are presented.

Hemoadsorption in the critically ill-Final results of the International CytoSorb Registry.

The aim of the current paper is to summarize the results of the International CytoSorb Registry. Data were collected on patients of the intensive care unit. The primary endpoint was actual in-hospital mortality compared to the mortality predicted by APACHE II score. The main secondary endpoints were SOFA scores, inflammatory biomarkers and overall evaluation of the general condition. 1434 patients were enrolled. Indications for hemoadsorption were sepsis/septic shock (N = 936); cardiac surgery perioperatively (N = 172); cardiac surgery postoperatively (N = 67) and "other" reasons (N = 259). APACHE-II-predicted mortality was 62.0±24.8%, whereas observed hospital mortality was 50.1%. Overall SOFA scores did not change but cardiovascular and pulmonary SOFA scores decreased by 0.4 [-0.5;-0.3] and -0.2 [-0.3;-0.2] points, respectively. Serum procalcitonin and C-reactive protein levels showed significant reduction: -15.4 [-19.6;-11.17] ng/mL; -17,52 [-70;44] mg/L, respectively. In the septic cohort PCT and IL-6 also showed significant reduction: -18.2 [-23.6;-12.8] ng/mL; -2.6 [-3.0;-2.2] pg/mL, respectively. Evaluation of the overall effect: minimal improvement (22%), much improvement (22%) and very much improvement (10%), no change observed (30%) and deterioration (4%). There was no significant difference in the primary outcome of mortality, but there were improvements in cardiovascular and pulmonary SOFA scores and a reduction in PCT, CRP and IL-6 levels. Trial registration: ClinicalTrials.gov Identifier: NCT02312024 (retrospectively registered).

Hemoadsorption in 'Liver Indication'-Analysis of 109 Patients' Data from the CytoSorb International Registry.

BACKGROUND: Our aim is to report the results of the 'liver indication' subset of patients in the CytoSorb International Registry. METHODS: Structured data were recorded. Treatment characteristics and changes from T1 (start of hemoadsorption) to T2 (termination) were evaluated with a special focus on bilirubin, C-reactive protein, procalcitonin, interleukin-6, platelet levels, SOFA scores, mortality, and subjective assessment by the attending physicians. RESULTS: Until January 2021, from the total 1434 patients, 109 (age: 49.2 ± 17.1 years, 57.8% males) received treatment for hyperbilirubinemia. APACHE II-predicted mortality was 49.6 ± 26.8%. In the study, 91% of patients were alive at the termination of hemoadsorption and improvement was observed by the physicians in 75 cases. Overall, 65 (59.6%) patients died in the hospital, and 60 (55.0%) died in the ICU. Patients received a median of two treatments for a median of 43 h (interquartile range: 24-72 h) in total. Serum bilirubin levels reduced significantly to -4.6 (95% CI: -6.329 to -2.8) mg/dL. Thrombocytopenia was reported in four patients as an adverse event. CONCLUSIONS: We report the largest case series on hemoadsorption for 'liver indication' from the CytoSorb International Registry. The finding of significant bilirubin removal observed in our study could have substantial impact in designing and executing further studies on the effects of hemoadsorption in liver dysfunction, which are certainly warranted.

Hemoadsorption treatment with CytoSorb® in patients with extracorporeal life support therapy: A case series.

INTRODUCTION: Extracorporeal life support is an increasingly used technique for respiratory and cardiocirculatory support. Besides primary organ dysfunction, an excessive systemic hyperinflammatory response can be the underlying cause for acute organ failure necessitating extracorporeal life support therapy, or it may be associated with the extracorporeal life support itself. Controlling this overwhelming inflammatory response using CytoSorb® hemoadsorption has been shown to be associated with improved hemodynamics and restored metabolic balance resulting in preserved organ functions. METHODS: In this retrospective case series, we describe 23 patients undergoing extracorporeal life support therapy and CytoSorb hemoadsorption. Cytokine levels were monitored, hemodynamic and metabolic variables were recorded, and outcome measures such as duration of organ support, intensive care unit mortality, and hospital mortality were noted. RESULTS: CytoSorb treatment was associated with a trend toward a reduction in plasma cytokine levels (first treatment median interleukin-6 pre 595 vs post 350 pg/mL (n.s.); second treatment median interleukin-6 317 vs 108 pg/mL, p < 0.05), a reduced vasoplegic response resulting in a reduction in vasopressor requirements (first treatment median norepinephrine pre 0.15 vs post 0.02 µg/kg/min (n.s.); second treatment median norepinephrine 0.1 vs 0.02 µg/kg/min, p < 0.05) as well as rebalancing of deranged metabolic parameters (first treatment median lactate pre-treatment 6 vs post-treatment median lactate 2 mmol/L, p < 0.05). The hemoperfusion treatment was well tolerated and safe, without the occurrence of any CytoSorb device-related adverse events. CONCLUSION: Hemoadsorption may offer a potentially promising therapeutic option for critically ill patients undergoing extracorporeal life support therapy, with cytokine reduction and a consecutively mitigated inflammatory response, decreased vasoplegia, and improved organ function as seen in our patients.

CytoResc - "CytoSorb" Rescue for critically ill patients undergoing the COVID-19 Cytokine Storm: A structured summary of a study protocol for a randomized controlled trial.

OBJECTIVES: Approximately 8 - 10 % of COVID-19 patients present with a serious clinical course and need for hospitalization, 8% of hospitalized patients need ICU-treatment. Currently, no causal therapy is available and treatment is purely supportive. The main reason for death in critically ill patients is acute respiratory failure. However, in a number of patients a severe hyperinflammatory response with excessively elevated proinflammatory cytokines causes vasoplegic shock resistant to vasopressor therapy. A new polystyrene-based hemoadsorber (CytoSorb®, Cytosorbents Inc., New Jersey, USA) has been shown to adsorb effectively cytokines and other middle molecular weight toxins this way reducing their blood concentrations. This has been routinely used in clinical practice in the EU for other conditions where a cytokine storm occurs and an observational study has just been completed on COVID-19 patients. We hypothesized that the extracorporeal elimination of cytokines in critically ill COVID-19 patients with suspected hyperinflammation and shock may stabilize hemodynamics and improve outcome. The primary endpoint is time until resolution of vasoplegic shock, which is a well implemented, clinically relevant endpoint in critical care studies. TRIAL DESIGN: Phase IIb, multicenter, prospective, open-label, randomized, 1:1 parallel group pilot study comparing the additional use of "CytoSorb" to standard of care without "CytoSorb". PARTICIPANTS: Patients are recruited from the Intensive Care Units (ICUs) of 7 participating centers in Germany (approximately 10 ICUs). All patients aged 18- 80 with positive polymerase chain reaction (PCR) test for SARS-CoV-2, a C-reactive protein (CRP) ≥ 100 mg/l, a Procalcitonin (PCT) < 2 ng/l, and suspected cytokine storm defined via a vasoplegic shock (Norepinephrine > 0.2 µg/min/kg to achieve a Mean Arterial Pressure ≥ 65mmHg). Patients are included irrespective of indication for renal replacement therapy. Suspected or proven bacterial cause for vasoplegic shock is a contraindication. INTERVENTION AND COMPARATOR: Within 24 hours after meeting the inclusion criteria patients will be randomized to receive either standard of care or standard of care and additional "CytoSorb" therapy via a shaldon catheter for 3-7 days. Filter exchange is done every 24 hours. If patients receive antibiotics, an additional dose of antibiotics is administered after each change of "CytoSorb" filter in order to prevent underdosing due to "CytoSorb" treatment. MAIN OUTCOMES: Primary outcome is time to resolution of vasoplegic shock (defined as no need for vasopressors for at least 8 hours in order to sustain a MAP ≥ 65mmHg) in days. Secondary outcomes are 7 day mortality after fulfilling the inclusion criteria, mortality until hospital discharge, Interleukin-6 (IL-6) measurement on day 1 and 3, need for mechanical ventilation, duration of mechanical ventilation, duration of ICU-stay, catecholamine dose on day 1/2/3 after start of "CytoSorb" and acute kidney injury. RANDOMIZATION: An electronic randomization will be performed using the study software secuTrial® administered by the Clinical Study Center (CSC) of the Charité - Universitätsmedizin Berlin, Germany. Randomization is done in blocks by 4 stratified by including center. BLINDING (MASKING): The trial will be non-blinded for the clinicians and patients. The statistician will receive a blinded data set, so that all analyses will be conducted blinded. NUMBERS TO BE RANDOMIZED (SAMPLE SIZE): As this is a pilot study with the goal to examine the feasibility of the study design as well as the intervention effect, no formal sample size calculation was conducted. A total number of approximately 80-100 patients is planned (40-50 patients per group). Safety assessment is done after the inclusion of each 10 patients per randomization group. TRIAL STATUS: Please see the study protocol version from April 24 2020. Recruitment of patients is still pending. TRIAL REGISTRATION: The study was registered on April 27 2020 in the German Registry of Clinical Trials (DRKS) under the number DRKS00021447. FULL PROTOCOL: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol.

Extracorporeal membrane oxygenation and cytokine adsorption.

Extracorporeal membrane oxygenation (ECMO) is an increasingly used technology for mechanical support of respiratory and cardio-circulatory failure. Excessive systemic inflammatory response is observed during sepsis and after cardiopulmonary bypass (CPB) with similar clinical features. The overwhelming inflammatory response is characterized by highly elevated pro- and anti-inflammatory cytokine levels. The excessive cytokine release during the overwhelming inflammatory response may result in multiple organ damage and failure. During ECMO therapy activation of complement and contact systems occur which may be followed by cytokine release. Controlling excessively increased cytokines may be considered as a valuable treatment option. Hemoadsorption therapy may be used to decrease cytokine levels in case of excessive inflammatory response and due to its unspecific adsorptive characteristics also substances like myoglobin, free hemoglobin or bilirubin. Controlling pro-inflammatory response with hemoadsorption may have positive impact on the endothelial glycocalix and also may be advantageous for maintenance of the vascular barrier function which plays a pivotal role in the development of tissue edema and oxygen mismatch. Hemoadsorption therapy seems to offer a promising new option for the treatment of patients with overwhelming inflammatory response leading to faster hemodynamic and metabolic stabilization finally resulting in preserved organ functions.

Treatment dose and the elimination rates of electrolytes, vitamins, and trace elements during continuous veno-venous hemodialysis (CVVHD).

INTRODUCTION: During continuous renal replacement therapy, achievement of recommended treatment dose is important. However, relevant substrate loss may occur and recommended nutrition during critical illness could not be sufficient for higher dialysis doses. We investigated the correlation of dialysis dose and substrate loss for a broad range of dialysis doses. METHODS: Forty critically ill patients with acute kidney injury undergoing citrate CVVHD were included in this prospective study. Three different corresponding blood flow (BF) and dialysate flow (DF) rates were applied (BF/DF: 100 ml/min, 2000 ml/h; 80 ml/min, 1500 ml/h; 120 ml/min, 2500 ml/h). Delivered effluent flow rate (DEFR) was calculated and correlated with losses of vitamins, electrolytes, and trace elements during recommended nutritional supplementation. RESULTS: For folic acid, vitamin B12, zinc, inorganic phosphate, and magnesium, no correlation of losses and DEFR was detected. For ionized calcium, a correlation was observed and additional substitution was required. CONCLUSION: Clinically relevant loss of folic acid, vitamin B12, zinc, inorganic phosphate, and magnesium was not observed for differently used dialysis doses of CVVHD, and the loss was covered sufficiently by daily recommended nutritional supplementation. Increased loss of ionized calcium for higher dialysis doses occurred during citrate CVVHD. Therefore, a strict protocol must maintain calcium homeostasis to avoid calcium depletion.

Hemoadsorption treatment of patients with acute infective endocarditis during surgery with cardiopulmonary bypass - a case series.

INTRODUCTION: Infective endocarditis is a serious disease condition. Depending on the causative microorganism and clinical symptoms, cardiac surgery and valve replacement may be needed, posing additional risks to patients who may simultaneously suffer from septic shock. The combination of surgery bacterial spreadout and artificial cardiopulmonary bypass (CPB) surfaces results in a release of key inflammatory mediators leading to an overshooting systemic hyperinflammatory state frequently associated with compromised hemodynamic and organ function. Hemoadsorption might represent a potential approach to control the hyperinflammatory systemic reaction associated with the procedure itself and subsequent clinical conditions by reducing a broad range of immuno-regulatory mediators. METHODS: We describe 39 cardiac surgery patients with proven acute infective endocarditis obtaining valve replacement during CPB surgery in combination with intraoperative CytoSorb hemoadsorption. In comparison, we evaluated a historical group of 28 patients with infective endocarditis undergoing CPB surgery without intraoperative hemoadsorption. RESULTS: CytoSorb treatment was associated with a mitigated postoperative response of key cytokines and clinical metabolic parameters. Moreover, patients showed hemodynamic stability during and after the operation while the need for vasopressors was less pronounced within hours after completion of the procedure, which possibly could be attributed to the additional CytoSorb treatment. Intraoperative hemoperfusion treatment was well tolerated and safe without the occurrence of any CytoSorb device-related adverse event. CONCLUSIONS: Thus, this interventional approach may open up potentially promising therapeutic options for critically-ill patients with acute infective endocarditis during and after cardiac surgery, with cytokine reduction, improved hemodynamic stability and organ function as seen in our patients.

Cytokine Reduction in the Setting of an ARDS-Associated Inflammatory Response with Multiple Organ Failure.

A 45-year-old male was admitted to our hospital with a small bowel obstruction due to torsion and was immediately scheduled for surgical intervention. At anesthesia induction, the patient aspirated and subsequently developed a severe SIRS with ARDS and multiple organ failure requiring the use of ECMO, CRRT, antibiotics, and low dose steroids. Due to a rapid deterioration in clinical status and a concurrent surge in inflammatory biomarkers, an extracorporeal cytokine adsorber (CytoSorb) was added to the CRRT blood circuit. The combined treatment resulted in a rapid and significant reduction in the levels of circulating inflammatory mediators. This decrease was paralleled by marked clinical stabilization of the patient including a significant improvement in hemodynamic stability and a reduced need for norepinephrine and improved respiratory function as measured by PaO2/FIO2, ventilator parameters, lung mechanics, and indirect measures of capillary leak syndrome. The patient could be discharged to a respiratory weaning unit where successful respiratory weaning could be achieved later on. We attribute the clinical improvement to the rapid control of the hyperinflammatory response and the reduction of inflammatory mediators using a combination of CytoSorb and these other therapies. CytoSorb treatment was safe and well tolerated, with no device-related adverse effects observed.

Treatment of post-cardiopulmonary bypass SIRS by hemoadsorption: a case series.

The use of cardiopulmonary bypass (CPB) in cardiothoracic surgery results in a well-known activation of the immunologic response. In some cases, however, this triggered immunologic response may be excessive, leading to a severe systemic inflammatory response syndrome (SIRS) and induced organ dysfunction. For example, patients frequently develop hemodynamic instability with hypotension and low systemic vascular resistance. To date, different therapeutic approaches, such as steroids, have been tried to control this maladaptive postoperative SIRS response, yet definitive proof of clinical efficacy is missing. A new cytokine adsorber device (CytoSorb; CytoSorbents) may be a useful approach to control hyperinflammatory systemic reactions by reducing a broad range of proinflammatory cytokines and other inflammatory mediators. This may, in turn, help to reestablish a physiologic immune response and help to restore deranged clinical parameters in these patients. In this retrospective case series study, we describe 16 cardiac surgery patients following prolonged CPB with post-CPB SIRS and subsequent acute kidney injury, who were then treated with hemoadsorption using CytoSorb in combination with continuous renal replacement therapy (CRRT). Treatment of patients with CytoSorb who presented with severe post-CPB SIRS resulted in a reduction of elevated cytokine levels, which was associated with a clear stabilization of deranged hemodynamic, metabolic, and organ function parameters. Treatment was well tolerated and safe, with no device-related adverse events occurring. CytoSorb therapy combined with CRRT is a potentially promising new treatment approach to achieve hemodynamic stability, cytokine reduction, and improved organ function in cardiac surgery patients who develop post-CPB SIRS.

Validation of portal vein flow measurement by color flow Doppler sonography in a porcine model of septic shock.

OBJECTIVE: To compare portal vein flow values gained by color flow Doppler sonography with simultaneously derived data from an ultrasound transit time flow probe. DESIGN: Repeated, simultaneous flow measurements were performed in a prospective study investigating the effect of various drugs on hepatosplanchnic perfusion and energy balance in a long-term model of stable, hyperdynamic endotoxin shock. SETTING: Investigational animal laboratory. SUBJECTS: Domestic pigs. INTERVENTIONS: Alterations in respirator setting were studied with regard to their effect on the quality of color flow Doppler data in comparison to flow probe data. Additional experiments included variation in PEEP level in conjunction with volume resuscitation. MEASUREMENTS AND RESULTS: Respiratory rates of 14-18/min led to color Doppler flow values consistently 20-40% above simultaneously measured flow probe data. Temporary apnea led to enhanced agreement of data. Reduction in respiratory rate to 8/min with increase in tidal volume consistently led to color Doppler data within 10% of the corresponding flow probe values. CONCLUSIONS: A short-term period of respirator-dependent, constant portal vein inflow enables color Doppler sonography to detect correct values in a clinically relevant setting of hyperdynamic endotoxin shock.

Implementation of continuous renal replacement therapy with regional citrate anticoagulation on a surgical and trauma intensive care unit: impact on clinical and economic aspects-an observational study.

BACKGROUND: Regional citrate anticoagulation (RCA) is being increasingly used during continuous renal replacement therapy (CRRT) in intensive care units as an alternative to systemic heparin anticoagulation. However, due to its availability in a variety of solutions and dialysis systems, RCA is still considered a complex intervention, possibly leading to confusion and pitfalls in everyday practice. We therefore tested retrospectively if the introduction of RCA as a new anticoagulation strategy for CRRT was feasible and had not negatively impacted efficacy, safety, metabolic stability, filter lifetime, and cost-effectiveness compared to well-established systemic heparin. METHODS: This observational, retrospective study was performed on a non-cardiac surgical and trauma intensive care unit (ICU) in a university hospital. All charts of patients receiving one of the CRRT techniques from May 2006 to April 2010 were reviewed. The first 60 consecutive patients receiving CRRT with regional citrate anticoagulation after its implementation in February 2008 (continuous veno-venous haemodialysis, Multifiltrate® with integrated CiCa® system, AV 1000 S® filter, n = 60) were included in the study. The last 50 consecutive patients with systemic heparin anticoagulation therapy (continuous veno-venous haemodiafiltration, PRISMAFLEX®, AN69® filter, n = 50), treated immediately before the introduction of RCA, were used as a historic control group. RESULTS: Both treatment modalities were effective in terms of uraemia control. Patients in the citrate group presented with significantly higher pH levels, lower ionized calcium levels, and higher sodium levels compared with the heparin treated group, however, without notable adverse clinical events. Interestingly, mean circuit lifetime was significantly longer in the citrate group (48.6 ± 24.2 h vs. 18.8 ± 13.5 h; p < 0.0001). Both treatment modalities were cost-effective. CONCLUSIONS: Our results suggest that the implementation of regional citrate anticoagulation was safe and effective. Due to the retrospective design of the study and inherent limitations therein concerning several baseline parameters, i.e. different filters, modes of dialysis, and flow parameters not having been standardized, we were unable to draw a causative effect relationship. Nonetheless, our results warrant further study.

Metabolic effects of norepinephrine and dobutamine in healthy volunteers.

The objective of the present study was to evaluate the effects of norepinephrine (n = 9) and dobutamine (n = 7) on carbohydrate and protein metabolism in healthy volunteers in comparison with a control group (n = 9). Norepinephrine (0.1 microg/kg min), dobutamine (5 microg/kg min), or placebo was infused for 240 min. The plasma concentration of glucose, lactate, epinephrine, norepinephrine, insulin, and glucagon were determined. Glucose and urea production and leucine flux were measured using a tracer technique. Norepinephrine caused a persisting rise in plasma glucose concentration, whereas the increase in glucose production was only transient. A minor increase in plasma lactate concentration was observed, but it did not exceed the physiological range. No change in leucine flux, urea production, or plasma concentration of insulin, glucagon, or epinephrine was found. Dobutamine slightly decreased glucose production, whereas the plasma concentration of glucose and lactate did not change. The reduction in leucine flux was paralleled by a decrease in urea production. No change in the plasma concentration of insulin, glucagon, or the catecholamines was observed. In conclusion, both norepinephrine and dobutamine have only minor metabolic effects. Because glucose production is enhanced by alpha1- and beta2-adrenoceptor stimulation, we conclude that dobutamine is only a weak agonist at these adrenoceptors. These minor metabolic actions may make both compounds suitable for critically ill patients because no further increase in metabolic rate should be caused.

How to treat esophageal perforations when determinants and predictors of mortality are considered.

BACKGROUND: Published lethality rates of esophageal perforation (EP) vary depending on patient- and disease-related factors. This study was designed to evaluate how these factors impact death. Furthermore, we calculated the predictive accuracy of the Mortality Prediction Model (MPM II) and the Simplified Acute Physiology Score (SAPS II) for in-hospital death. Conclusions about treatment decisions were drawn based on our data and analysis of recent literature. METHODS: Every patient who was treated for EP at our department from December 2001 to July 2008 is included in this study. Logistic regression analyses of various risk factors, such as etiology, time interval, size, comorbidities, localization, type of treatment, and preexisting pathologies of the esophagus on death, were performed. RESULTS: Of the 41 patients diagnosed with EP, nine died (21%). The most important risk factor concerning death was cirrhosis of the liver (0 vs. 89% mortality; odds ratio, 208; P<0.001). Accuracy for lethality risk prediction was calculated with MPM II and SAPS II on admission, and afterward the characteristic increase that occurred was evaluated by using receiver operator characteristic curves. Optimal results were achieved by using a characteristic SAPS II increase (AUC 0.86; P: 0.009) after the patient was admitted to the intensive care unit. CONCLUSIONS: Our study was the first to demonstrate that a rapid or continuous increase more than 40 of the daily SAPS II clearly indicates that a high risk of death is imminent. This should be used as a reevaluation factor when choosing a treatment strategy.
