Filter by:Objective: Test the ability of vibration to produce physiologic, biochemical, and anatomic changes consistent with exercise that would help prevent the development of muscle weakness that occurs when patients are immobile for long periods of time.
The objective of this study is to obtain the absolute bioavailability of voriconazole in critically ill ICU patients, because pharmacokinetics can be different in critically ill patients due to alterations in function of various organs and body systems compared with healthy volunteers.
Patients with liver cirrhosis are at risk for development of renal failure, usually after a precipitating event such as infection or bleeding. This form of renal failure has a high morbidity and mortality and may be partly caused by increased intra-abdominal pressure secondary to ascites. Recent studies have shown that paracentesis (and the resulting decreased IAP) can increase urinary output and decrease renal arterial resistive index in patients with hepatorenal syndrome (a very pronounced form of renal failure in cirrhosis patients). The aim of this study is to evaluate the influence of Paracentesis on intra-abdominal pressure and kidney function in critically ill patients with liver cirrhosis and ascites across a wider range of kidney function. Kidney function will be evaluated using several estimates of glomerular filtration rate and measures of kidney injury i.e. cystatin C, serum NGAL, creatinine clearance, urinary output and renal arterial resistive index.
Intra- abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are a cause of organ dysfunction in critically ill patients. IAH develops due to abdominal lesions (primary IAH) or extra-abdominal processes (secondary IAH). Secondary IAH arises due to decreased abdominal wall compliance and gut edema caused by capillary leak and excessive fluid resuscitation. Decreasing intra-abdominal pressure (IAP) using decompressieve laparotomy has been shown to improve organ dysfunction. However, laparotomy is generally avoided in patients with secondary IAH due to the risk of abdominal complications. Acute kidney injury (AKI) is one of the first and most pronounced organ failures associated with IAH and many patients with AKI in the ICU require renal replacement therapy (RRT). Fluid removal using continuous RRT (CRRT) has been demonstrated to decrease IAP in small series and selected patients. The aim of this study is to evaluate whether fluid removal using CVVH in patients with IAH, fluid overload and AKI is feasible and whether it has a beneficial effect on organ dysfunction (compared to CVVH without net fluid removal).
Sleep is disrupted in the PICU. This disruption has been reported in studies that have used: (a) observation of sleep-wake cycles (b) self-reports by children themselves , and (c) objective measures (e.g., electroencephalograph( EEG). Noise and light levels have been correlated with profound sleep disruption in the PICU . Sleep disruption is known to have a profound impact on the overall health of a child, both from a physiological and a psychological standpoint . In addition, sleep disruption has been shown to change cortisol levels, cause impaired immune responses and impair cognitive function in both children and adults . Disruption in sleep also is known to impair healing through these many complex connections with other homeostatic processes in the human body. What is the effect of wearing earplugs in critically ill children admitted to the PICU on: 1. Sleep states 2. Physiological stability (e.g. melatonin, cortisol and immune status) 3. Sleep habits after discharge from the PICU (on the general pediatric unit, 2 weeks and 2 months after discharge), and 4. Child behavior at 2 weeks and 2 months after discharge from the PICU by parent report on the Child Behavior Checklist (CBCL).
