Time to Protein Target Using a High Whey Protein Enteral Nutrition in Critically Ill Patients
Critically IllThis study evaluates the feasibility of a high whey-protein enteral nutrition formula in 20 ventilated ICU patients. The primary endpoint of study is the feasibility to attain the individualized protein target (≥1.2 g/kg ideal body weight/day) 96-hours after ICU admission. Secondary endpoints include tolerance and efficacy in terms of the amino acid response in blood.
HbA1c and Outcomes in the Critically Ill
Critical IllnessBackground: Glycated hemoglobin A1c (HbA1c) has been linked to poor outcomes in the cardiac surgery, septic and critically ill patient population. It is a promising test to understand the complex relationship between glycemia, diabetes and outcomes in patients admitted to the intensive care unit. Hypothesis: An elevated HbA1c value on admission to an intensive care unit (ICU) is associated with poor outcomes.
New Stable Isotope Method to Determine Protein Requirements in Critically Ill Children
Critically IllThe 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.
Sedation in the Intensive Care Unit
Critical IllnessRespiratory FailureHigh-risk critically ill patients often require mechanical ventilation either to primarily support the respiratory function or when the ventilation is insufficient to maintain adequate gas exchanges as a result of other organ impairment. In order to tolerate this aggressive mechanical support, enhance patient synchrony with the ventilator, and relieve pain and anxiety, analgesia and sedation are provided. It is suggested that an inappropriate use of sedation and analgesia may prolong the duration of mechanical ventilation and increase the risk of specific adverse outcomes such as ventilator associated pneumonia. Despite the widespread use of sedation, little information is available concerning the effect of varying the level of sedation on patients' subsequent mental health. We designed a randomized controlled trial to investigate the efficacy of sedation with the goal of maintaining the patient cooperative and interactive compared to the administration of sedation with the goal of maintaining the patient sedated. The first goal will be achieved by a discontinuous injection of a sedative, while the second goal will be achieved by a continuous infusion of the same sedative. In both groups pain relief will be provided in the same fashion with equal endpoints on a pain scoring scale. Our primary aim is to investigate whether differences in the occurrence of post-traumatic stress disorders (PTSD), anxiety, and depression are related to the choice of sedation-analgesia strategies. Secondary endpoints include the length of ICU stay, as indicated by the time to discharge from the ICU, the time to separation from mechanical ventilation, the rates of pulmonary and extra-pulmonary complications, and hospital length of stay. These endpoints will be compared between the two groups.
Health and Quality of Life One Year After Discharge From the Intensive Care Unit (ICU)
Critically IllThe goal is to capture the Quality of life and survival of patients one year after the stay at ICU. Data will be collected during the stay in the ICU and evaluated. One year after the ICU stay patients will be send a Quality of Life questionnaire they need to fill out and return. All data will be evaluated together.

Indirect Calorimetry: SensorMedics Vmax vs GE Carescape - a Method Comparison Study
Nutrition AssessmentCritical Illness1 moreDosing of nutrition in PICUs is mainly based on patient weight and assumptions on clinical status. There is however poor correlation between these calculations and actual energy consumption measured with indirect calorimetry (IC). Available equipment for IC has however been too cumbersome to use in daily clinical practice. Of relative new date is IC integrated in modern ventilators. This functionality is easy to use, but we do not know if the results are reliable for children. This study is a method comparison study comparing measurements done with SensorMedics Vmax ("gold standard") vs GE Carescape (modern ventilator with Integrated IC) in children undergoing intensive care treatment.
Observational Study of Blood Pressure Measurements and Continuous Dialysis
Kidney FailureRespiratory Failure2 moreDialysis is used to control the fluid balance and metabolic state of patients with kidney disease. Control of the metabolic state, via electrolytes, can be monitored using labs that are routinely drawn from patients undergoing continuous hemodialysis. Control of fluid removal is much more difficult. This study aims to determine whether changes in the blood pressure associated with breathing correlate with or predict intolerance to fluid responsiveness with continuous dialysis. We hypothesize that a measurement of changes in blood pressure with breathing called arterial pulse pressure variation may be able to predict the ability to remove fluid during continuous renal replacement therapy.
FLOTRAC/VIGILEO in Acute Circulatory Failure
Critically IllAcute Circulatory Failure1 moreAcute circulatory failure may be related to hypovolemia. Fluid loading increases stroke volume in approximatively half of challenges. Determining fluid responsiveness prevents unnecessary fluid loading. Passive leg raising (PLR) provides a transient increase of 300 ml in venous return for a short time. The measurement of stroke volume (SV) before and after a PLR test allows physician to detect fluid responsiveness, when stroke volume increases is higher than 15 %. Beside thermodilution, the use of non invasive device to measure stroke volume becomes largely employed. Arterial Pressure based Cardiac Output (APCO), provided by the Flotrac/Vigileo system, does not required specific materials nor repeated calibration. The third generation software is believed to be more accurate and more precise for SV measurement. The aim of this study is to test the performance of the Flotrac/Vigileo device in a situation of rapid venous return changes induced by PLR and then by fluid loading. Patients will be classify posteriorly in responders and non responders, according to the magnitude of the fluid loading-induced SV changes measured by transthoracic echocardiography.
