NCT06840756
Red blood cell (RBC) transfusions are selected based upon matching donor and recipient blood group: donor and recipient sex are not considered when selecting blood for transfusion. Hence, transfused patients can currently receive sex-matched and/or unmatched RBCs when transfusions are given. Sex-matched stem cell transplants, and some solid organ transplants, have shown that sex-matching donor to recipient improves patient outcomes. Recent exploratory studies have also suggested that patient outcomes could be improved by sex-matching for RBC transfusion. There is emerging evidence of underlying biologic mechanism(s) to support these observations. This study is designed as a randomized controlled trial and will explore the impact on patients who receive RBC transfusions from donors of the same sex ("sex-matched") compared with donors of the opposite sex ("sex-mismatched"). The trial will study adult patients admitted to the Intensive Care Unit who require an RBC transfusion. Patients will be assigned (through a process called randomization) to receive sex-matched RBCs or sex-mismatched RBCs to determine if there is a difference in mortality between those receiving matched versus mismatched RBCs. The results of this trial could have direct implications on resources, blood inventory, and RBC transfusion ordering practices.
NCT07448805
Researchers at the Department of Intensive Internal Medicine and the Department of Endocrinology and Diabetology will conduct a study to verify the accuracy and safety of the new Syai Tag system for continuous glucose monitoring in patients in intensive internal care. Almost 150,000 people in Slovenia have diabetes, so keeping a close eye on blood sugar levels is key to preventing complications. The new sensors for continuous monitoring are available over the counter and certified as medical devices. The study will include at least 100 patients who will need blood sugar monitoring during their stay in the intensive care unit. Each patient will have two small sensors placed on each upper arm to continuously measure their blood sugar levels, but these values will not be visible to medical staff. At the same time, healthcare professionals will perform routine blood sugar measurements, and researchers will then compare the accuracy of both methods. The procedure is safe and painless, and patients will receive the same quality of care as usual.
NCT07222007
The aim of this retrospective cohort study is to compare the safety and efficacy of induction agents for tracheal intubation in critically ill adult patients.
NCT04776486
Evaluation of glomerular filtration rate using iohexol plasma clearance in critically ill patients with augmented renal creatinine clearance
NCT07178626
When the subjects are admitted to the department, the researchers will monitor potential biomarkers of gastrointestinal injury before administering enteral nutrition (a small amount of blood is drawn, serum is separated by centrifugation, and the serum sample is frozen for final centralized biomarker detection), and measure the antral movement index under ultrasound (300ml of warm water is injected into the stomach before measurement, and then the antral movement is observed for 6 minutes) Then, monitor whether the patient has developed feeding intolerance within 7 days of the ICU
NCT07249749
ICU mortality indicates the severity of disease, healthcare quality, and the efficacy of interventions. The severity scores are tools to predict the risk of mortality in the ICU, and the APACHE II score is frequently used for this purpose. However, studies validating the score in Colombia are limited. There is uncertainty about the precision and discrimination capacity of the APACHE II score in a population that varies from the original, with varying diseases, and in a different timeline. The investigators determined to evaluate: 1. Evaluate the rate of mortality in the ICU by type of disease and type of admission. 2. The factors associated with mortality. 3. Validate the performance of the APACHE II score as a predictor of mortality.
NCT07093450
The goal of this clinical trial is to learn if an educational intervention with audit and feedback on physicians and health care professionals who participate in antimicrobial treatment decisions can reduce the use of antimicrobials in adult patients admitted to a sample of Brazilian intensive care units (ICUs). The educational intervention is based on a literature review of current recommendations for a more rational use of antimicrobials and microbiological tests in daily ICU practice. The main questions it aims to answer are: * Does the educational intervention reduce the antimicrobial consumption in the intensive care units? * Does this educational intervention aiming to reduce antimicrobial utilization in accordance with the latest guidelines have any safety signals regarding ICU mortality rates or ICU length-of-stay? Researchers will compare (1) ICUs sequentially randomized to this quality improvement educational intervention aimed at improving antimicrobial utilization to (2) the same ICUs at months where the educational intervention has not been delivered yet. Each participant ICU will transition to the quality improvement intervention approximately each month, starting at July, 2025. This quality improvement intervention is based on current recommendations for antimicrobial stewardship from regulatory agencies and medical societies, including cognitive aids for physicians to improve decision-making regarding the commencement of antimicrobials, their duration and antimicrobial time-outs. The investigators hypothesize that intensivists (ICU doctors) need to embrace antimicrobial stewardship as a core competence of their daily activities.
NCT07143695
Increased days of MV are not without hazards, including barotraumas and ventilator-associated pneumonia. Similarly, premature separation of MV is associated with increased mortality secondary to adverse cardiorespiratory events. Therefore, the time of weaning should be wisely evaluated. There is growing evidence concerning respiratory muscles dysfunction that contributes to difficulty or prolonged liberation from MV.
NCT05108441
A vast majority of children admitted to paediatric intensive care (PICU) present with faltering growth during their admission. Muscle mass loss is an early, intense and frequent phenomenon in this setting, which is associated with impaired outcomes. Recent international guidelines recommend monitoring both nutritional status and muscle mass throughout hospital stay. Recent studies have used quadriceps femoris (QF) measurements as a surrogate for lean mass assessment, and monitored them with bedside ultrasound (QF thickness and QF cross sectional area). However, ultrasound cross sectional area inter-operator reproducibility has not been validated so far, and none of these ultrasound measurements has been validated against their gold standard i.e. magnetic resonance imaging measurements. This validation process should be conducted to allow interpreting ultrasound muscle measurements, prior to the implementation of ultrasound measurments into clinical practice. We hypothesise that ultrasound measurements of QF thickness and cross sectional area are reliable compared to the magnetic resonance imaging gold standard, and that QF cross sectional area has a reliable inter-operator reproducibility.
NCT07124442
Intensive Care Units are specialized, technologically advanced hospital units that provide continuous monitoring and care from multiple healthcare disciplines for patients who are critically ill and face a high risk of death or serious health problems. Prolonged periods of immobility, which are common during treatment in these units, can cause serious complications such as muscle weakness, decline in physical function, and a lower quality of life. There are scoring systems designed to predict the severity of a patient's illness and their likely outcomes, such as the scoring system called the Acute Physiology and Chronic Health Evaluation version two. However, these scoring systems are not yet widely used as a regular part of patient care. Although weakness and wasting of muscles away from the center of the body are known to affect the recovery process of patients who survive intensive care treatment, the connection between how severe the illness is and the strength of the muscles used for breathing, the structure of peripheral muscles, and their biomechanical characteristics is still not fully understood. This study aims to explore these relationships to help improve physiotherapy and rehabilitation treatments for patients in intensive care.
NCT07108179
Whether diabetic or non-diabetic patients, blood glucose management during ICU hospitalization is essential. This study aims to evaluate the accuracy of the iCan Continuous Glucose Monitoring (CGM) System for detecting blood glucose levels in ICU patients, as well as its value in prognostic evaluation, to provide reference for blood glucose management in critically ill patients.
NCT07073508
This study aims to assess the clinical relevance of renal artery duplex ultrasound in critically ill patients with acute kidney injury (AKI) in terms of the renal resistive index (RRI).
NCT06495489
The management of septic shock patients includes the infusion of fluids, however fluids may be deleterious if the patient does not respond by increasing cardiac output. By consequence, it is now recommended to predict the fluid response (fluid or preload responsiveness) before infusing them. In this protocol, the investigators will include critically ill patients mechanically ventilated patients under a spontaneous mode, for whom the physician in charge has decided to test preload responsiveness. The investigators will collect from the continuous monitoring of arterial pressure of the patient the Pulse Pressure (PP) which is the difference between systolic arterial pressure and diastolic arterial pressure and the Pulse Pressure Variation (PPV) automatically displayed by the monitor in addition to other clinical (hemodynamic, respiratory) parameters. After one minute of Passive Leg Raising manoeuvre (PLR) the investigators collect the same parameters and the investigators will compare the changes of these parameters in patients who are preload responsive to patients who are not. Preload responsiveness will be defined by echocardiographic parameters before and during PLR. More exactly, a surrogate of cardiac output measured by echocardiography wich is VTI of the sub-aorti flow; an increase of more than 12% defines apreload responsive patient.

The mini fluid challenge (mini\_FC) is a functional hemodynamic test which has been used in different clinical contexts to assess fluid responsiveness. This test is performed by rapidly injecting a small aliquot of fluid (100 ml over 1 minute), which is followed by the infusion of the residual aliquot of fluid. Since the threshold of the mini\_FC identified by the literature is rather small (5% of stroke volume (SV) increase after the 100 ml bolus to discriminate between responder and non-responder), it is crucial that the hemodynamic tool assessing this change could be reliable. Moreover, the SV changes with inspiratory/expiratory movements and the increase after the mini\_FC should also consider the physiological fluctuations of the SV. In the literature this test has been performed by means of tolls with different least significant change of the SV. The least significant change (LSC) represents the smallest difference between successive measurements of SV that can be considered to be a real change and not attributable to chance. The purpose of this study is to assess the agreement among MOSTCARE system (4.5\& of SV LSC described in the literature) and the echocardiography (about 10% of SV LSC described in the literature) with the PICCO system (about 1% of SV LSC described in the literature - considered the gold standard) in discriminating fluid responsiveness after a mini\_FC
NCT07005258
Invasive candidiasis are the most common form of fungal infection in critically ill patients, particularly intra-abdominal candidiasis (IAC), which is associated with high morbidity and mortality. The current diagnostic gold standard relies on conventional fungal culture, which has a long turnaround time and may delay targeted antifungal therapy. Non-culture-based assays such as 1,3-β-D-glucan lack specificity for early and definitive diagnosis. Molecular diagnostics, including PCR, offer faster and more specific detection, but their clinical use remains limited. The CandID PLUS PCR assay targets major Candida species and has not yet been evaluated on peritoneal fluid. The CANDIDIAG study aims to assess the feasibility and diagnostic performance of the CandID PLUS PCR in detecting Candida spp. in peritoneal fluid from ICU patients with suspected IAC. This study constitutes a post-hoc analysis of the pBDG2 study (Prospective evaluation of the peritoneal 1.3 Beta-D-glucan for the diagnosis of intra-abdominal candidiasis in the critically ill patients) registered with the number NCT 03997929). Therefore, all patients have been already recruited. For the CANDIDIAG study, we will use the biological collection of peritoneal fluid issue from the pBDG2 study. All patients with confirmed intra-abdominal candidiasis are identified. We will test de CandID PCR, retrospectively, on their peritoneal fluid and compared the results with the fungal culture.
NCT06779331
Hypophosphatemia is a common disorder in critically ill patients, appearing in 15-35% of Intensive Care Unit (ICU) admissions. Its reasons are multifactorial, including sepsis, refeeding syndrome, and continuous renal replacement therapy. Hypophosphatemia is generally accepted as a predictor of poor outcomes, such as prolonged ventilation and higher mortality. However, conflicting evidence exists and several works demonstrated no effect on length of ventilation, nor mortality. We have recently demonstrated no effect of hypophosphatemia on mortality and length of ventilation. However, both parameters were affected by energy delivery to the patient, with higher energy delivery associated with lower mortality and longer length of ventilation, suggesting a complex interaction between energy delivery to the patient, hypophosphatemia appearance, and patient outcomes. This raised hypothesis that hypophosphatemia is a marker of recovery, as in fulminant hepatic failure, or recovery after hepatectomy. Phosphate is mainly an intracellular anion, with only 1% of its total body amount is extracellular. It is absorbed from the small intestine, mainly at the jejunum, both through passive para-cellular and active trans-cellular process. Phosphate is excreted in the urine, after being filtered in the glomeruli, and reabsorbed mainly in the proximal tubule (less than 10% of the reabsorption occurs in the distal nephron), by sodium-phosphate co-transporters. Phosphate regulation in the body is complex. It is regulated by vitamin D, parathyroid hormone (PTH), and fibroblast growth factor 23 (FGF-23). Therefore, phosphate regulation is affected both from intestine dysfunction and kidney injury. Although hyperphosphatemia in various kidney injury is well described, the effect of kidney function regarding phosphate excretion in critically ill patients with hypophosphatemia has been scarcely described. French and Bellomo described 7 patients who had decreased phosphate kidney reabsorption during hypophosphatemia. Charrone et. al demonstrated increased phosphate excretion after IV phosphate infusion to 47 critically ill patients with hypophosphatemia. Dickerson et. al demonstrated higher rates of hypophosphatemia in 20 thermally injured patients (compared to 20 multiple trauma patients) despite greater phosphate delivery through nutrition, along with increased (although insignificant) phosphate urinary excretion in this group. This might suggest that increased renal phosphate loss has a role in hypophosphatemia development. Better understanding these processes is important, with regard to the effect of nutritional support and hypophosphatemia effects on patients' outcomes. This study aims to describe urinary phosphate excretion in critically ill patients with regard to kidney function, phosphate serum level, and phosphate intake.
NCT06705374
Intensive care is directed towards patients with severe illness or risk of serious outcomes following, for example, surgery. Central venous pressure (CVP) is an important part of the hemodynamic assessment of patients in surgery and the intensive care unit (ICU). CVP is normally measured via a central venous catheter (CVC) inserted through the subclavian or internal jugular vein, with the tip placed at the junction to the right atrium. A pressure tubing is connected to one of the branches of the CVC and then connected to a pressure sensor that sends a digital signal to the monitoring screen where CVP can be read in mmHg. To accurately read CVP, the pressure sensor must be positioned at the level of the right atrium. Different external reference points are used nationally and internationally to locate the correct height for the pressure sensor. This study aims to investigate the most commonly used external reference points for CVP measurement in various body positions compared to CVP measured via a solid state pressure catheter in the right atrium (RAP).
NCT06557629
Enteral nutrition intolerance, manifested in delayed gastric emptying and high gastric residual, is a common problem in critically ill patients in intensive care, with adverse consequences on patients' outcomes. A decrease in the levels of the ghrelin hormone in these patients may contribute to this problem. The gastric residual test (GRV) is used to assess enteral absorption and gastric motility, but the traditional methods can lead to inaccuracy and waste of resources. In recent years, the use of ultrasound (PoCUS) to assess GRV has developed, but its effect on the rate of reaching the caloric goal has not yet been evaluated.
