Active clinical trials for "Critical Illness"

Variable PSV is a new ventilatory mode which delivered a pressure support "variable" from 0 to 100% variation of the set PSV level.This study aimed to compare the ventilatory behavior, sleep quality and gas exchange between VARIABLE (or Noisy)-PSV and "standard" (or fixed)-PSV during the weaning phase of critically ill patients who required mechanical ventilation.

The primary objective is to assess the effect of fish oil-enriched enteral and parenteral nutrition on blood oxygenation in critically ill patients.

The impact of fever and its management in different medical and surgical populations of critically ill patients has not been explained to date. The current study aims to assess the safety and efficacy of treatment of critically ill patients with a permissive versus aggressive fever treatment strategy.

The study will examine the effect of amino acid supplements and enhanced physiotherapy on physical recovery following critical illness in intensive care.

The principal research question to be answered by this study is whether an exercise based rehabilitative intervention following critical illness can generate improvements in exercise capacity and quality of life beyond current (usual) care. The investigators will also aim to demonstrate that such an intervention is both practical and cost-effective.

The central purpose of this proposal is to study the short-term effects of sedation with sympatholysis, using α2 adrenergic agent Dexmedetomidine, on sleep and inflammation in critically ill patients with Acute Lung Injury and Acute Respiratory Disorder Syndrome (ALI/ARDS). An additional objective is to determine the effect of Dexmedetomidine sedation on the in-vitro production of sleep-modulating inflammatory cytokines by peripheral blood mononuclear cells of critically ill patients with ALI/ARDS.

Almost all critically ill children who are mechanically ventilated require sedation and analgesia. Providing effective sedation for children in the PICU requires careful balancing of the need for sedation with the adverse effects associated with sedative medications. Clonidine is often used as an adjunctive sedative and analgesic in children but a well designed and adequately powered randomized trial is required to test the effect of clonidine-based sedation. Because there are no large randomized trials of sedation related interventions among critically ill children there are many unknown factors. This pilot trial, focussing on feasibility outcomes will assess the feasibility of, and inform the design of, a larger randomized controlled trial which will focus on clinically important outcomes.

The main objective of this proof-of-concept study is to demonstrate that the only administration of L-arginine, based on a suspected deficit monitored by nasal nitric oxide measurement, can improve immune functions in critically ill patients at high risk of nosocomial infection.

The purpose of this study is to determine if naso-jejunal feeding (feeding beyond the stomach) improves the efficacy of enteral feeding (feeding into the gut) in critically ill patients. The study hypothesis is that in patients who fail to establish enteral feeding via the nasogastric route, introduction of nasojejunal feeding will lead to more effective enteral feeding than the current regime involving staged introduction of promotility agents.

Sleep disruptions are extremely common in high-risk critically ill patients. The investigators want to analyse oral melatonin potentialities as a sedative and a free-radicals scavenger for critically ill patients, and secondarily for preventing Delirium during their ICU stay and post-traumatic stress disorders after ICU discharge.
