Filter by:Background: After mechanical ventilation, 5-20% of patients with acute respiratory failure would depend on ventilator support more than 14 days because of critical-illness weakness and their underlying diseases such as heart failure and chronic obstructive pulmonary disease. Hypothesis: Electric muscle stimulation(EMS) will improve their muscle strength and shorten their ventilator days. Design: Randomized controlled trial. Adult patients with mechanical ventilation more than 14 days are eligible. EMS would be applied in experimental group 32 minutes/day on their bilateral thigh.
Critical illness polyneuropathy and/or myopathy (CIPNM) is a severe complication of critical illness. Retrospective data suggest that early application of IgM-enriched intravenous immunoglobulin (IVIG) may prevent or mitigate CIPNM. Therefore, the primary objective was to assess the effect of early IgM-enriched IVIG versus placebo to mitigate CIPNM in a prospective setting.
Brief Summary Cerebral Autoregulation is a well known physiological response to blood pressure changes to maintain the cerebral perfusion. The critically ill patients are submitted to different situations that can impair the cerebral autoregulation as sepsis, sedation drugs and mechanical ventilation. The delirium on ICU has been described as a bad prognosis factor, increasing the mortality and length of stay. The physiopathology of delirium has been related to cerebral perfusion. The delirium has been related to long term cognitive impairment. Material and Methods: This is a physiological prospective study that will be done in a 14 bed medical-surgical ICU. The investigators will enroll 100 ventilated patients, septic and non-septic. The investigators will measure cerebral autoregulation every 48-72 hours from admission on ICU. Neurological biomarkers (Neurological Specific Enolase, S100 beta and Vascular Endothelial Growing Factor) will be done at inclusion, 72 hours and 7 days. Clinical data, delirium presence, analytic data and ventilatory parameters will be registered every day. At hospital discharge, a psychologist will do a cognitive evaluation using specific tests. The cognitive evaluation will be repeated at 3, 6 and 12 months. Anticipate results: Some items like mechanical ventilation, sepsis and sedation can impair cerebral autoregulation. The impairment of cerebral autoregulation is related to delirium in ICU and long cognitive impairment.
The purpose of this study is to determine whether the use of different sedatives affect the weaning process from mechanical ventilation in intensive care patients.
Severe sepsis and septic shock are life threatening medical emergencies and are among the most significant challenges in critical care. Case reports and case series suggest that plasma-derived protein C concentrate may improve the outcome of patients with acquired protein C deficiency. Evidence has accumulated on the clinical relevance of the PC pathway in modulating overwhelming inflammation and preventing coagulation derangements, two key mediators of organ damage, and thus of mortality and morbidity, in sepsis. The experience collected through these studies shows that PC is safe, in that it is not associated with bleeding or severe allergic complications,and possibly useful, at least to improve the coagulation abnormalities brought about by sepsis. Unfortunately, however, all we know comes from case series or case reports or an underpowered randomized controlled study. A randomized clinical trial, adequately powered for mortality or clinically relevant outcome, is necessary to confirm PC efficacy.The aim of this study is to demonstrate that Protein C zymogen has clinically relevant implications in terms of reduction of thromboembolic events, 30 days mortality, length of intensive care and hospital stay, time on mechanical ventilation, length of ICU and hospital stay. The study will also confirm that there is no bleeding concern with the use of Protein C concentrates.The study drug will be administered in the Intensive Care Unit for 72 hours and the patients observed till ICU discharge. Telephone followup will be performed at 30 days and at one year.
The premise of this study is that enteral tranexamic acid will help to maintain small bowel integrity, which is often compromised by critical illness due to inadequate cardiovascular perfusion (i.e., shock), and that maintenance of small bowel integrity will decrease morbidity in critically ill patients.
It has been shown that the stress that occurs during trauma, infection and/or shock depletes many of the body's resources such as Vitamin C (ascorbic acid) which may contribute to further complications. The purpose of this study is to determine the effectiveness of high doses of Vitamin C in critically ill patients.
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.
To determine whether specialized enteral nutrition support can improve oxygenation status in critically ill patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) comparing to a standard enteral nutritional formula.
Hypomagnesemia (low magnesium) is an electrolyte imbalance commonly found in up to 65% of critically ill patients. Possible consequences of hypomagnesemia include neuromuscular and neurologic dysfunction, heart arrhythmias, and alterations in other electrolytes. Data has shown that critically ill patients with hypomagnesemia have a significantly higher mortality rate than patients with a normal magnesium level. The most simple and commonly used test to diagnose hypomagnesemia is a serum magnesium level. Based on the magnesium level and symptoms of hypomagnesemia, patients may be replaced with either oral or intravenous (IV) magnesium. When replacing magnesium via the IV route, approximately half of the dose is retained by the body while the remainder is excreted in the urine. The low retention rate is due to the slow uptake of magnesium by cells and decreased magnesium reabsorption by the kidneys in response to the delivery of a large concentration of magnesium. The purpose of this study is to determine whether an eight hour compared to a four hour infusion of IV magnesium sulfate results in a greater retention of the magnesium dose.
