Filter by:Record the renal resistive index and hemodynamic parameters ( record the cardiac output and stroke volume if the patient's next to kin agree to undertake a PiCCO monitoring ) before and after resuscitation for severe sepsis or septic shock patients, to determine whether the changes of resistive index or hemodynamic parameters, especially the cardiac output can be a better parameter to predict AKI
An early and efficient enteral nutritional support could improve the clinical outcomes of brain injured critically ill patients. Gastrointestinal feeding intolerance defined as an increased gastric residual volume frequently occurs in these patients. Previous experimental studies have suggested that a small-peptide enteral feeding formula could promote the gastric emptying compared to a whole-protein formula. An improved gastrointestinal tolerance of enteral nutrition should allow a rapid increase in the daily caloric intake and enhance nutritional support of brain injured critically ill patients.
Compared with AN69 hemofilter, AN69 ST hemofilter may prolong the time of hemofilter and decrease the quantity of heparin during continuous renal replacement therapy in critically ill.
This is a study of plasma HBP -levels of a previously published trial of G-CSF in critically ill patients (Pettila et al. Critical Care Medicine 2000). The original study was a prospective, randomised, double-blind, placebo-controlled trial of filgrastim in patients with acute respiratory failure requiring intubation. In this substudy, the investigators evaluated the effect of filgrastim on HBP -concentrations in critically ill patients.
A total of ninety patients (52men and 38women) were included in the study. Forty five patients developed septic complication during ICU stay (sepsis group). Forty five patients were critically ill without evidence of infectious organism (SIRS group). At admission, Patients data include clinical status; SOFA score; central venous pressure; laboratory analysis and arterial blood gas analysis were measured. Routine cultures were obtained. The attending physician evaluated the patients for sepsis, severe sepsis, or septic shock as long as their stay in ICU. A serum level of TNF-a and SOFA score was monitored.
The main purpose of the study is to examine if changes in pharmacokinetics of important antiinfectives in Critically Ill patients in need of continuous renal replacement therapy (CRRT), causes inadequate concentrations in plasma. The effect of different modus of CRRT: CVVH and CVVHD will be compared, as well as type of filter, filter lifetime etc. Hypothesis: The risk of incorrect dosage of antiinfectives - to low/ to high- is increased in critically ill patients receiving CRRT. Inadequate plasma concentrations of antiinfectives may contribute to increased mortality in this group.
Specifically designed enteral formulations may improve the gastrointestinal tolerance during early enteral nutrition in the critically ill patient. This pilot trial will permit testing the design of the full-scale study providing valuable data on the expected effect of the formulation, the variability, thus helping to better estimate the required sample size.
Critically-ill patients who have long stays in the hospital often face prolonged periods of bed rest. It is known that these patient develop profound weakness and debilitation. The effectiveness of existing muscle activation devices that could otherwise prevent the onset of debilitation in an immobilized patient has not been demonstrated widely in this cohort. It is hypothesized that using thermal methods to augment existing muscle activation techniques may demonstrate improved performance with no corresponding change in the safety profile.
The aim of this study is to compare two nutritional regimes in critically ill patients. Patients will be randomized to standard care (25 kcal per kg) or to hypocaloric nutrition (15 kcal per kg). The main outcome will be the SOFA (sequential organ failure assessment) score. The hypothesis is that hypocaloric hyperproteic diet decreases the incidence of organic failure in these patients.
The need for certain components of food (i.e. protein) for critically ill children is not clear. It is important to have critically ill children fed adequately to prevent that their condition becomes worse or that recovery takes longer. Research methods used in the past to investigate the need for protein (Nitrogen Balance calculations), were not sensitive enough in severely ill children. The purpose of this study is to develop a new research method to determine the need for protein in severely ill children. In order to develop this new method, more information is needed on the way the body of these children uses protein in 24-hours. In the present study during 24-hours 8 children of age less than 18 years who are admitted to either the Pediatric ICU or the Cardiovascular ICU. Subjects will receive a standard nutrition, providing an age specific amount of protein (age ≤ 3: 2.52 protein g/kg BW.d; age 4-6: 1.8 protein g/kg BW.d; age > 10: 1.44 protein g/kg BW.d) via tube feeding. They will also receive a mixture of stable isotopes of amino to investigate protein behavior in the body (protein kinetics) both by infusion in their blood and together with the nutrition. Blood will be drawn every 60 minutes during the 24-hour period and the behavior of protein and the concentrations in blood of amino acids and urea will be measured. Urine will be collected to measure nitrogen balance. The investigators will compare the results of this nitrogen balance method with the results of the stable isotope method. PIM2, PRISM, SIRS criteria will be used to get information on the severity of illness of the subjects. Also body weight and length as well as body composition of the subjects will be measured at the start and after the 24-hour period. Body composition will be measured by Bioelectrical Impedance Spectroscopy. Endpoints of the study are net whole-body protein synthesis (protein balance), 24-hour pattern of protein balance, 24-hour urea production, 24-hour nitrogen balance, 24-hour contribution of arginine kinetics to whole body protein breakdown, 24-hour muscle protein breakdown, splanchnic amino acid extraction and plasma amino acid concentrations.
