Arterial Blood Pressure-complexity in Septic Patients
SepsisArterial blood pressure (ABP) is regulated by multiple, interconnected feedback loops resulting in a variable and complex time course. According to the "decomplexification theory of illness", disease is characterised by a loss or impaired function of feedback loops resulting in a decreased complexity of the ABP-time course and an impaired adaptability of the cardiovascular system. Decomplexification of physiologic parameters has been shown to occur in coronary heart disease, Parkinson's and Hodgkin's disease, and in subarachnoid hemorrhage, but has not been evaluated in sepsis. This study is intended to test the hypothesis that complexity of ABP is lower in cardiac surgery versus non-cardiac surgery septic patients, decreases as severity of sepsis increases to severe sepsis and septic shock, is associated with outcome three month after sepsis.
Early Warning System for Clinical Deterioration on General Hospital Wards
Escalation of CareCardiopulmonary Arrest3 moreThe goal is to develop a two-tiered monitoring system to improve the care of patients at risk for clinical deterioration on general hospital wards (GHWs) at Barnes-Jewish Hospital (BJH). The investigators hypothesize that the use of an automated early warning system (EWS) that identifies patients at risk of clinical deterioration, with notification of nurses on the GHWs when patients are identified, will reduce the risk of ICU transfer or death within 24 hrs of an alert. As a substudy, the investigators will pilot the use of a wireless pulse oximeter to establish feasibility and to develop algorithms for a real-time event detection system (RDS) in these high-risk patients.
Respiratory Variations for Predicting Fluid Responsiveness
SepsisRespiratory Physiological Phenomena1 moreHypovolemia and acute circulatory failure affects more than 60% of patients hospitalized in intensive care or resuscitation. The volume expansion (VE) by fluid replacement therapy is the first treatment improve circulatory function. However, too much VE can be harmful. So, the use of dynamic predictive indicators of fluid responsiveness is recommended in patients with sepsis.In patients with spontaneous ventilation, few studies have evaluated these parameters. In mechanical ventilation, indices based on the respiratory variation of the diameters of vena cava have been studied and validated to predict the response to VE. However there is no similar study in spontaneously breathing patients without ventilatory support. The investigators hypothesize that the respiratory variations in the IVC diameters and femoral artery flow during standardized respiratory cycles are predictive factors of fluid responsiveness in spontaneously breathing patients with sepsis, acute circulatory failure, and regular cardiac rhythm.
the Influence of Prophylactic and Empirical Anti-fungal Treatment in Severe Sepsis Patients With...
Intra-abdominal PerforationThis prospective intended to observe the influence of prophylactic and empirical anti-fungal treatment on Severe Sepsis patients with perforations. With the consent of patients' legal guardian for prophylactic use of antifungal agents, patients were divided into two groups: prophylactic group and Empirical group.
Assessment of a Proposed Microbiological Alert and Its Impact on a Sepsis Campaign
SepsisThe aim of the present study was to evaluate the ability of health-care professionals in addressing sepsis, and the impact of a telephone call upon receival of blood cultures in the clinical microbiology department, from a clinical microbiologist, in the early management of sepsis.
Central Venous Catheter Replacement Strategies in Adult Patients With Major Burn Injury
Catheter-related Bloodstream InfectionComplication of CatheterThe aim of this project is to answer the following questions: To determine the incidence of catheter related bacteremia (CRB) with three strategies of central venous catheter exchange in critically ill adult patients with major burn and to determine the regimen that will minimize the risk of bacteremia. To determine the incidence rate of catheter colonization in adult patients with major burns. The scientific knowledge to be acquired through this project is of likely benefit to the care of critically ill patients with burns injury as follows: The intention is to improve the outcomes in critically ill patients by minimizing one of the most frequent causes of infection in the Burn Intensive Care Unit, those from central venous catheters. Decreasing infections will decrease morbidity, decrease length of stay, decrease costs, and decrease mortality.
Outcome Following Vitamin C Administration in Sepsis
Severe SepsisThis study is designed to determine if Vitamin C administration to septic patients will result in an improvement in organ dysfunction which occurs during a septic illness. Hypothesis: 1. Vitamin C in sepsis will reduce the injury to organs 2. Vitamin C will reduce the length of time on a ventilator, length of stay in the intensive care unit and in hospital.
Clinical Trial With Catheter Locking TauroSept® (Taurolidine 2%) or Saline Solution 0,9%
Catheter Related Blood Stream InfectionsThe purpose of this study is to determine if TauroSept® taurolidine 2% is more efficient than saline solution 0.9% as a catheter lock solution in preventing catheter related blood stream infections in patients with home parenteral nutrition.
Diagnosis of Septicaemia by Detection of Microbial DNA in Blood in Severe Infections
Febrile NeutropeniaEndocarditis1 moreThe primary purpose is to improve and quicken the microbial diagnosis in severe infections, since only one third of the cases are documented by blood cultures and adequate anti-infective therapy in the 48 hours reduced mortality and morbidity. Our hypothesis is that detection of microbial DNA in blood by real time PCR may increase the number of cases diagnosed for bacteraemia or fungemia and shorten the time to positive results, which will provide information for an adequate anti-infectious therapy.
The Only Blood Culture for Diagnosis of Bacteremia - Comparative Study of Practice
Bloodstream InfectionCurrent recommendations for the diagnosis of bacteremia based on the embodiment February-March blood cultures separated by a minimum interval of 30 minutes. Each blood culture comprises seeding a pair of aerobic and anaerobic vials inoculated each with 5 to 10 ml of blood. The sensitivity and specificity of this technique depends essentially on the amount of blood removed since there is a direct relationship between the volume of blood inoculated into each flask and the efficiency of the technique. A preliminary study conducted at the University Hospital of Caen found that 14-30% of patients depending on the services had received only one blood culture. In addition, at least four blood cultures in 24 hours were taken for 10 to 20% of patients. The practice of a single blood culture reduces the sensitivity of the analysis due to insufficient total amount of blood collected. The practice of too many blood cultures increases the risk of false positive (presence of contaminating bacteria), generates extra work for healthcare personnel (and laboratory) and represents a significant cost for an unproven benefit. The investigators propose to evaluate a single blood culture sampling technique with seeding 4 vials (2 aerobic and anaerobic 2).
