Active clinical trials for "Critical Illness"

A randomized controlled clinical trial. 24 adult ICU patients will be recruited upon decision to administer fluid bolus of 500ml of crystalloid. The fluid will then be randomized to be infused at controlled room temperature or warmed to body temperature. Hemodynamic measurements will be made for 2 hours following the bolus, and laboratory values will be noted. The hypothesis is that part of the hemodynamic response will differed in response to cooling, and be larger in the cold group.

The aim of this study is too determine the effect of enteral protein supplementation on biochemical measures of inflammation and protein metabolism in critically ill surgical patients. The investigators will also collect data on important clinical outcomes, including infectious complications, duration of mechanical ventilation and other measures of recovery from critical illness. Hypothesis: That early supplemental protein will increase serum concentrations of transthyretin at three weeks after the onset of illness or injury. Secondarily, the investigators will test whether supplementation, reduces infectious complications and increases ventilator-free days.

A 2x2 factorial randomized study to evaluate the effect of a balanced crystalloid solution compared with 0.9% saline, and of rapid vs. slow infusion on clinical outcomes of critically ill patients

The purpose of this study is to assess the efficacy of calcifediol (25-hydroxyvitamin D) and calcitriol (1,25-dihydroxyvitamin D) in preventing and reducing the severity of acute kidney injury (AKI) in critically ill patients.

This study was to determine efficacy of the non-returning catheter valve for reducing catheter associated urinary tract infection compared with conventional urine bag in critically ill patients.

Background: Few studies have addressed the situation of procedural pain and the use of preemptive analgesia for turning in patients under mechanical ventilation. Aim: Evaluation effect of preemptive fentanyl on the incidence of pain during turning maneuvers in critically ill patients under mechanical ventilation. Design: Single-center clinical trial, national, randomized, double-blind, with a parallel group, and two arms of treatment: saline placebo and fentanyl. Primary Endpoint: Incidence of pain during the turning procedures that are carried out by nurses measured by means of the Behavioral Pain Scale (BPS). Study Population: Critically ill patients, age > 18 years, admitted to ICU and expected to require mechanical ventilation for at least 24 h. Sample Size: 80 patients divided into the two groups (40 patients each). Statistical Analysis: A preliminary descriptive analysis will be carried. Later, results of primary end point will be comparing after the eventual corrections of corresponding variables using a multivariable approach. The AUC variable will be analyzed by a t-test for unpaired data. A second analysis using a multivariate approach will be carried out for those factors considered as clinically relevant in relation to pain and therefore a logistic regression will be used. Ethical Considerations: The study will be strictly conducted following the Declaration of Helsinki and the protocol and Standard Operating Procedures (SOPs) to ensure compliance with the Good Clinical Practice (GCP) standards. It is the responsibility of the researcher to obtain the valid informed consent from the guardian / legal representative, as the patient's condition will not allow to consent. Before obtaining the consent the investigator will explain to each guardian / legal representative the nature of the study, its purpose, the procedures, the estimated duration, the potential risks and benefits associated with the participation, as well as any inconvenience that this may involve. Duration of Treatment: The treatment has a maximum duration of 60 min for each patient. The follow-up includes visits and has duration of 6 consecutive days. Safety Assessment: Potential side effects of treatments will be recorded. Frequent adverse effects of fentanyl administration include respiratory depression, apnea, muscle rigidity, bradycardia and transient hypotension.

Continuous enteral nutrition is used to feed patients in intensive care who are unable to eat normally. The goal of this observational study is to learn about the uptake of nutrients from feeding formula. The study method will first be applied in healthy persons to establish workability and normal values, then in patients in the intensive care unit to learn how nutrient uptake is affected by critical illness. The main questions this study aims to answer are: what is the time course of uptake of phenylalanine (an amino acid) and glucose (a sugar) from enteral feeding formula given continuously over several hours what is the time course of the filling volume of the stomach during continuous enteral feeding Participants receive feeding formula through a nasogastric feeding tube and blood samples are taken at short intervals to analyse uptake of nutrients into blood. Simultaneously, the filling volume of the stomach is measured by gastric ultrasound.

The goal of this woldwide observational study is to investigate various aspects of fluid and vasopressor therapy in critically ill invasively ventilated patients. The main questions it aims to answer are: What is the global current practice of fluid and vasopressor therapy? What are associations between this practice and clinical outcomes? Participating intensive care units will gather detailed information about fluid and vasopressor therapy prescribed to participants. Participating intensive care units will also gather information about participant outcomes such as duration of invasive ventilation, length of stay and mortality

High flow nasal cannula administration in critically ill patients is frequently used to improve acute respiratory failure or to prevent respiratory failure after extubation. It acts generating a mild positive pressure in the airways and by reducing respiratory effort of patients. However to the best of our knowledge, no study to date has directly measured the amount of positive pressure generated in the trachea of patients. The primary aim, therefore, of this study measures this positive pressure after extubation in critically ill patients.

Vascular dysfunction is an important mechanism involved in organ failure, in the setting of sepsis condition, with different types of circulating endothelial cells.Transcriptom analysis via RNAseq in different types of circulating endothelial cells, comapring critically ill patients with or without sepsis will allow determining differential gene expression for signal pathways in endothelial alteration and restoration associated with sepsis.
