Advances in critical care medicine have dramatically improved the survival of critically ill patients requiring prolonged mechanical ventilation. However, there are no systematic follow-up, rehabilitation, or psychoeducational interventions for these vulnerable patients or their family caregivers who contribute to survivor recovery and rehabilitation. Major barriers to developing these programs for survivors of prolonged mechanical ventilation and their caregivers include the following: 1. There is inadequate information about the determinants of long-term functional outcomes for a diverse group of survivors of prolonged mechanical ventilation. 2. There is inadequate information about the needs of survivors of prolonged mechanical ventilation and their family caregivers across the trajectory of illness (i.e., from the ICU to the community). 3. There is a poor understanding of the development of ICU-acquired muscle injury. Towards RECOVER is the very first study to identify survivors of prolonged mechanical ventilation who are at-risk for poor functional outcomes, to identify elements of the care-giving situation that put caregivers at risk for poor quality of life and mental health, to catalogue the rehabilitative needs of patients and family caregivers across the illness trajectory, and to evaluate the mechanism of critical illness associated muscle injury. The RECOVER Program consists of Four Phases: - Phase I: Towards RECOVER - Phase II: RECOVER development and pilot testing - Phase III: RECOVER randomized controlled trial - Phase IV: Long-term implementation of RECOVER
Fluid therapy is an important part of the management of patients with hemodynamic instability in the intensive care unit. By increasing cardiac preload, it aims at elevating cardiac output (CO) and thus restoring hemodynamic conditions in patients who are preload responsive. By contrast, volume administration can be deleterious in terms of pulmonary edema formation or other manifestations or fluid overload, especially in patients who are not preload responsive. Functional dynamic parameters that use heart-lung interactions, such as pulse pressure variation (PPV) and stroke volume variation (SVV) are considered accurate predictors of preload responsiveness in patients receiving fully controlled mechanical ventilation. However, in cases of spontaneous breathing activity where heart-lung interaction indices fail to predict fluid responsiveness, one needs parameters able to reliably predict the hemodynamic response of fluid administration. A new index that could indicate fluid responsiveness, so-called the fluid responsiveness index (FRI), has been elaborated. The advantage is that it could be used in patients who are not in control mechanical ventilation as well as in patients who are fully adapted to mechanical ventilation. The FRI is based upon the analysis of continuous arterial and continuous central venous pressure. The FRI is determined by the relation of cardiac and respiratory activity; both are evaluated by means of power spectrum analysis of the pressures recorded. The aim of this study is to test the value of the FRI to predict the hemodynamic response to fluid infusion in patients with hemodynamic instability not receiving fully controlled mechanical ventilation.
Glutamine is a major fuel for the intestinal tract and immune cells and therefore affects the intestinal permeability (IP) and infection rate at critically ill patients. The preferential route of glutamine supplementation at critically ill patients still remains open. Therefore the researchers will investigate IP, infection rate and treatment outcome at patients supplemented with either parenteral or enteral glutamine. A prospective randomized single blind study is performed at mechanically ventilated. Patients were randomly assigned to either parenteral (group P) or enteral (group E) glutamine supplemented group. Early enteral feeding is started in both groups. Patients are/will be treated with glutamine for five days. IP will be measured using lactulose/mannitol test (L/M) on the fourth day.
Critically ill patients frequently undergo contrast enhanced computed tomography (CT) to establish diagnoses and direct management. Contrast agents can disturb kidney function and result in kidney dysfunction. The investigators investigated the effects of high dose N-acetylcysteine (NAC) or placebo, in addition to hydration, in preventing kidney dysfunction following contrast enhanced CT) in critically ill adults in the intensive care units of two teaching hospitals.
In patients with high gastric residual volumes jejunal feeding is recommended. Jejunal feeding tubes can be placed in different ways. The endoscopic technique yields a success rate between 90 and 98% for a correct jejunal placement. However, it requires endoscopic equipment and trained staff. In contrast in small uncontrolled trials different unguided techniques resulted in success rates up to 75%, only. In this prospective randomized trial the success rate of a correct jejunal placement with the endoscopic technique is compared with the unguided frictional technique. The investigators hypothesize that the success rate of the unguided frictional placement method will be lower than the success rate of the endoscopic method.
Rationale: Enteral nutrition (EN) in the intensive care (ICU) patients is recommended as a standard of care. However, EN alone is often associated with insufficient energy intakes and increased complication rates. Recently the investigators proposed to decrease this deficit by combining EN and supplemental parenteral nutrition (SPN) whenever EN is insufficient (< 60% of their predicted energy needs) at day 3 after admission in the ICU. Objective: This study aims at: a/ investigating if the delivery of optimal nutrition support (100 % of predicted energy targets) in ICU patients by the combined administration of SPN and EN optimizes their clinical outcome; b/ implementing the new ICU nutrition guidelines. Study design: Prospective, controlled, randomized clinical study. Study site: Service of Intensive Care, Geneva University Hospital. Patient population: 220 ICU patients to be included: expected length of stay > 5 days, expected survival > 7 days, no contraindication to EN, obtained informed consent from themselves or their next of keen. Exclusion criteria: refusal of consent, age < 18 years, short bowel syndrome, significant persistent gastrointestinal dysfunction with ileus, high output proximal fistula (> 1,5 liter/d), patients receiving PN. Nutrition: At day 3 after admission, if energy input is < 60%; patients are randomized into either the "Control group" (EN alone) or the "SPN group" (EN + PN) to reach 100% of their predicted energy needs. Tight glycaemic control (target 6.0 to 8.3 mmol/l) to be achieved according to our local practice by insulin administration. Study endpoints: - Primary: nosocomial infections (CDC criteria) - Secondary: Mechanical ventilation duration, ICU and hospital length of stay, antibiotic free days, ICU complications (extra-renal epuration, neurological, cardiac and respiratory complications), energy and protein balance, 28 days clinical outcome.
The goal of this present proposal is to examine the efficacy of GLP-1 administered to control blood glucose in critically ill patients.
Animal studies showed that controlled mechanical ventilation (CMV) can induce dysfunction of the diaphragm, resulting in an early-onset and progressive decrease in diaphragmatic force-generating capacity, called ventilator-induced diaphragmatic dysfunction (VIDD).
The purpose of this study is to find out whether acute renal failure is associated with BK virus reactivation in postoperative/posttraumatic critically ill patients with severe SIRS/sepsis and shock.
