Active clinical trials for "Critical Illness"

This is a Randomized Controlled Trial . The purpose of this study is to assess the hypothesis that whether a high protein diet combined with a physical activity protocol in surgical cancer patients admitted to the ICU in the post operative period is associated with better physical function at the hospital discharge as well as a better quality of life.

The incidence of malnutrition in patients with severe neurological diseases is approximately 37%, among which hypoproteinemia is a common manifestation. It has been confirmed that serum albumin level is closely related to severity and mortality for patients. Protein is the basic component of tissue cells in the body, which plays an important role in the growth and development of senescent cells and the repair of damaged tissues. At present, the results of some randomized controlled studies show that it is difficult to achieve enough protein supplementation by commercial standard enteral nutrition agents alone, and additional protein supplementation is required. Commercial standard enteral nutrition preparations, whose whole protein components are casein and soy protein, do not achieve optimal uptake and utilization compared to whey proteins, which are more readily absorbed and utilized by the human gut. Whey protein and its hydrolyzed products have better nutritional quality than casein, which can provide high-quality nitrogen source for enteral nutrition and play an important role in correcting negative nitrogen balance, promoting wound healing and improving body immunity. Whether whey protein supplementation based on standard enteral nutrition preparation can improve serum albumin level and reduce the incidence of hypoproteinemia in patients with severe acute neurological disease has not been proved. In conclusion, we propose the hypothesis that compared with the standard enteral nutrition preparation regimen, the enteral nutrition regimen supplemented with whey protein in patients with severe neurological disease is more beneficial to improve the nutritional indicators of patients and reduce the occurrence of hypoproteinemia. It is expected that this randomized controlled trial will provide a new clinical basis for optimizing the enteral nutrition support program for patients with severe neurological diseases.

The aim of the study was to describe the feasibility of the nociception flexion reflex and the pupillary dilatation reflex as objective pain assessment tools in the Intensive Care Unit (ICU). Furthermore to describe the relationship between the responses and the standard of care pain evaluation in the critically ill sedated patients. Patients were under propofol / remifentanil or propofol / sufentanil sedation protocol during measurements in a stair-case increasing intensity model of standardized stimulations. (Stimulation intensity are similar to the stimulations of neuromuscular blocking agents monitoring.)

Hypotension and bradycardia are often observed following induction of dexmedetomidine or propofol sedation.Cardiac preload decrease by sedative agents was often considered as one of main causes for this hypotension.The investigators hypothesized that hypotension after induction of sedation is caused by decrease of preload by sedative agents,and passive leg raising (PLR)test could predict this event.Dexmedetomidine or propofol infusion in patients with circulatory failure decrease cardiac preload and enhance preload-dependency and fluid responsiveness.

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 pilot study designed to test feasibility of a psychotherapeutic intervention for the critically ill patients in intensive care units. Intervention is named Early Psychological Support for the Critically Ill (EPSCI)

The purpose of this study is to determine whether the environmental simulation of daytime and night time alternation as well as by the nutrition protocol corresponding to the daily rhythm are beneficially affect the recovery of patients treated in the Intensive Care Unit (ICU) requiring mechanical ventilation.

Purpose. Oral chemoprophylaxis has been advocated to reduce the incidence of Candida colonization and infection. However, Candida prophylaxis in intensive care unit (ICU) is still a matter of debate. Methods. Randomized, single-center trial studying single drug (nystatin) versus control in surgical ICU patients. Multiple-site testing for fungi were performed in each patient at ICU admission (T0) and subsequently every 3 days (T3, T6, T9…). The primary evaluation criterion was the time course of colonization index (CI) during ICU stay.

The purpose of this study is to evaluate the optimal technique for determination of the renal function of critically ill patients.

The investigators will evaluate the effects of of higher protein/amino acid dosing (≥2.2 g/kg/d) vs usual care of protein/amino acid dosing (≤1.2 g/kg/d) over muscle mass in nutritionally high risk ill patients.
