Filter by:Biofilm is a microstructure organised into aggregates of microbiological species within a polymeric matrix. As early as the 2000s, the Centers for Disease Control and Prevention (CDC) recognised the possible role of the biofilm lining endotracheal endotracheal tubes in the development of ventilator-associated pneumonia (VAP) , the most common infection in intensive care, with a high morbidity and mortality rate and a significant increase in hospital costs. Targeting biofilm therefore now appears to be a new area of interest for limiting the risk of VAP, and this rationale has led to the development of an intraluminal for abrading biofilm deposited on the inside of the intubation probe . Evaluation of this type of strategy nevertheless justifies the introduction of more precise methods for characterisation of the biofilm. To this end, the investigator carried out an initial clinical study describing the biofilm on intubation probes, BIOPAVIR 1, showing the existence of several biofilm structures, each associated with a specific microbiological signature. Several limitations including a lack of power due to an insufficient number of patients and the use of number of patients, and the use of a confocal microscopy technique with poor axial without the possibility of acquiring metabolic images of the biofilm. Based on the previous description of biofilm by optical coherence tomography (OCT), and a recent experience with an optimised form of high-resolution OCT, called full-field OCT, the investigator hypothesise that full-field OCT will allow more accurate characterisation of biofilm, due to its high spatial resolution and its potential ability to capture metabolic activity in the biofilm BIOPAVIR 2 proposes to use the performance of full-field OCT to better characterise the biofilm lining endotracheal tubes in patients undergoing mechanical ventilation in intensive care units. This project represents a first step towards understanding the link between the development of biofilm on intubation and the occurrence of VAP
The Analgesia Nociception Index (ANI) reflects the balance between sympathetic and parasympathetic tone. It is based on a specific interpretation of the R-R interval variation. During fluid removal by net ultrafiltration in patients with fluid overload and continuous renal replacement therapy, some data suggest that haemodynamic variation could be induced by the autonomic nervous system. The study aims to investigate ANI variations in this context and their association with the haemodynamic variations observed.
Rapid and accurate determination of body weight in adult intensive care patients is very important for both calculating target tidal volume during invasive mechanical ventilation support and dose dependent drug administration. In this patient group, measuring actual body weight with a calibrated scale by standing the patient up is often impossible due to acute illness. Instead, estimated body weight determined by health care personnel or estimated body weights calculated according to anthropometric measurements are used. These calculations have some limitations in showing actual body weight, and there is some controversial information in current literature regarding their validity in critically ill patients. There is newly developed patient transfer scale called Marsden M-999® manufactured by Marsden Weighing Machine Group Ltd, which has the advantage of being used in patients who are unable to stand up, in rapidly and accurately measuring the current body weight in critically ill patients. This study aimed to evaluate the validity of these methods by comparing the body weights calculated by visual estimation and various anthropometric methods in critically ill Turkish patients with the actual weight measured by the mentioned scale.
This study explores the significance of body temperature monitoring in hospitalized patients, particularly in critical care environments. With body temperature exhibiting considerable variability, fever, defined at a central temperature of 38.3°C, serves as a pertinent indicator across diverse medical conditions. Temperature measurement methods in Intensive Care Units (ICUs) range from routine peripheral measurements to more invasive central temperature monitoring. Critical patients with fever often receive antibiotic treatment, even without conclusive evidence of infection, as early intervention is linked to improved survival in septic patients. However, the complexity of individual variability, circadian rhythms, medication effects, and methodological limitations underscores the impracticality of defining fever with a singular temperature value. The thermal curve, representing the temporal evolution of temperature, emerges as a nuanced parameter in this context. This study seeks to establish the correlation between axillary temperature measurements, a conventional method, and temperatures recorded by thermal imaging cameras. Widely employed during the Covid-19 pandemic, these cameras offer non-invasive and contactless measurement, mitigating pathogen transmission risks, particularly in patients colonized by multidrug-resistant microorganisms or those with compromised skin integrity. The study also endeavors to evaluate the diagnostic validity of thermal imaging cameras for fever and hypothermia. The integration of thermal imaging cameras into a system capable of automated, real-time peripheral temperature acquisition suggests a potential paradigm shift in ICU temperature monitoring practices. Beyond immediate clinical applications, the amassed data from this system holds promise for training intelligent systems through machine learning algorithms. This strategic integration aims to predict critical events, such as the onset of fever, nosocomial infections, or shock, marking a forward-looking approach to patient management.
This study aims to evaluate the efficiency of the urea/creatinine ratio as a catabolism marker compared to indirect calorimetry to optimize nutritional support in critically ill patients.
Acute kidney injury is a common complication in critically ill patients. This condition can significantly prolong the length of hospital stay, increase the cost of hospitalization, and have a high mortality rate and a poor prognosis. Early assessment of patients' prognosis with acute kidney injury is vital for clinical treatment. Point-of-care ultrasound and renal injury biomarkers can be used to evaluate kidney injury at different levels. Therefore, it is speculated that dynamic monitoring can accurately predict the prognosis of patients with kidney injury.
The goal of this clinical trial is to investigate the effects of nutrition therapy guided by indirect calorimetry and nitrogen balance among critically ill patients with acute kidney injury. The main question it aims to answer whether nutrition therapy guided by indirect calorimetry and nitrogen balance could improve 28 days mortality among critically ill patients with acute kidney injury or not. type of study: clinical trial Participants will be provided enteral or parenteral nutrition after randomization(48-72 days after admissions) with total energy guided by indirect calorimetry measurements and total protein by nitrogen balance with maximum of 1.3 gram per kilogram per day for total of 14 days If there is a comparison group: Researchers will compare with the control groups (nutrition therapy provided by physician using clinical equation of choice or judgements to see if participants were provided with these interventions, their 28 days mortalities would be better
In a retrospective observational study, critically ill COVID-19 patients admitted to the ICU with the CoV-2 delta-variant between august 2021 and february 2022 were evaluated (ethics application nr. 129/22 of the ethics commssion of the university Ulm.
29.3% of bacteremias in intensive care units (ICU) are linked to vascular devices, with a significant proportion related to central venous catheters, and an influence on both morbility and mortality. It is now accepted that microbiological biofilm plays a key role on both bacterial and fungal development on inner surface of vascular devices but there is yet a lack of clinical relevant data documenting a causal relation between biofilm formation and bacteremias. We assume that a more precise characterization of central venous catheter-deposited biofilm could help us better understand invasive medical device-related healthcare infections in critically ill patients.
