Filter by:This study measures the cardioventilatory coupling in critically ill patients during mechanical ventilation in controlled mode (pressure controlled) and in patient-driven mode (pressure support and neurally adjusted ventilatory assist).
Enteral alimentation is the preferred modality of support in critical patients who have acceptable digestive function and are unable to eat orally, but the advantages of continuous versus intermittent administration are surrounded by controversy. This prospective, randomised study was designed to compare two enteral feeding methods with respect to changes in levels of leptin and ghrelin in ICU.
During weaning the work of breathing is transferred from the ventilator back to the patient. Approximately 40% of the time on ventilators is spent weaning. Studies support the use of screening protocols and tests of patient's ability to breathe spontaneously (SBTs) to identify weaning candidates. The investigators work demonstrates that once daily screening is the current standard of care. The conduct of daily ward rounds and once daily screening in ICUs is poorly aligned with the rapidly changing clinical status of critically ill patients. With respiratory therapists (RTs) in Canadian intensive care units (ICUs), a significant opportunity exists to screen patients more often, conduct more SBTs, and reduce the time spent on ventilators and in the ICU. Only one mechanical ventilation trial has focused on the elderly and no trial has evaluated weaning outcomes in the elderly and very elderly which may be influenced by the presence of comorbidities, frailty, malnutrition and treatment limitations. The investigators propose to conduct a pilot randomized trial in 100 elderly (>/= 65 years) critically ill adults comparing 'once daily' screening to 'at least twice daily' screening in 8 adult ICUs. In the proposed trial, the investigators will (i) evaluate their ability to recruit elderly (>/= 65 years) critically ill patients into a weaning trial and (ii) assess whether protocols can be adhered to similarly between elderly (65 to 80 years) and very elderly (>80 years) trial participants. Moreover, they will also address generalizability issues in the conduct of mechanical ventilation research by evaluating potential biases associated with exclusion criteria and consent between elderly and very elderly patients and obtain preliminary estimates of differences in important clinical outcomes between elderly and very elderly participants.
Rationale: A higher citrate dose during continuous venovenous hemofiltration provides better anticoagulation but possibly a higher risk of citrate accumulation in case of metabolic limitations. A higher citrate dose also increases magnesium loss in ultrafiltrate, while a negative magnesium balance is unwanted. Objective: Aim of this study is to determine the magnesium balance of citrate-based continuous veno-venous hemofiltration (CVVH) and to determine whether and to which extent the magnesium balance depends on citrate dose. Study design and methods: A prospective randomized study conducted in critically ill patients with acute kidney injury (AKI), treated with CVVH, with either low dose citrate (2.5 mmol/L blood flow in the filter) or high dose citrate (4.5 mmol/L blood flow in the filter) as anti-coagulant, targeting a postfilter ionized Calcium (iCa) of resp. 1.3-1.6 mg/dL (0.325-0.4 mmol/L) and 0.8-1.1 mg/dL (0.2-0.275 mmol/L). Post-filter blood as well as effluent aliquots and bloodconcentrations in the patient are tested for the following variables: (0 , 2 , 4, 6, 12 and 24 hrs): Total Magnesium (tMg) and total Calcium (tCa), ionized Ca (iCa)(bloodgas analyzer). In addition, hematocrit, albumin, total protein, ureum and creatinine and parathormone (PTH) are determined in arterial blood at 0 and 24 hrs or at the time of protocol exit and citrate concentrations in postfilter and arterial blood at 1 and 24 hrs or at protocol exit. Sample sites: arterial line, postfilter port (after postdilution and calcium compensation), effluent sample. All flow rates to be noted. Study population: Twenty patients admitted to intensive care, requiring continuous renal replacement therapy (CRRT) for AKI. Intervention: Anti-coagulation with either low dose citraat (2.5 mmol/L blood flow) or high dose citraat (4.5 mmol/L blood flow) targeting postfilter iCa of resp. 1.3-1.6 and 0.8-1.1 mg/dL. Both regimens are within standard protocolled CVVH treatment in the intensive care department.
The purpose of this study, in mechanically ventilated septic shock patients, is to determine whether a fluid loading strategy based on parameters derived from the transpulmonary thermodilution technique may lead to more ventilator free days compared to a fluid loading strategy based on the surviving sepsis guidelines.
The purpose of this project is to test an innovative method for managing pain in acutely ill hospitalized patients who are not able to report their pain verbally to health care professionals. Nurses will use a Pain Assessment and Intervention for the Non-communicative (PAIN) Algorithm to guide assessment of pain, selection of pain medications, and management of medication side effects. The researchers will evaluate whether patients who are managed with the PAIN Algorithm have less severe pain and increased use of pharmacologic pain management strategies than those who are not managed with the PAIN Algorithm. The study design is a non-randomized quasi-experimental cohort design with two cohorts who will be sequentially studied. In phase 1, patients will comprise the usual care group (UCG), or control cohort, defined as receiving pain assessment and management practices that nurses are currently performing on the study units. In phase 2 the PAIN Algorithm coupled with analgesic order sets will be introduced to nurses and physicians on all participating units as the intervention. Patients enrolled in this phase will be considered the intervention group (IG), also called the experimental cohort. Nurses will be enrolled from the participating inpatient units to provide data on the clinical utility of the PAIN Algorithm
The purpose of this study is to test the efficacy of a novel cleaning device in keeping silver-coated endotracheal tubes free from bacterial colonization.
This is part 2 of the #NCT01618240 under the same IRB protocol #2010P001919. The primary objective of this study is to examine factors that are related to sleep-disordered breathing and upper airway patency in critically ill patients who have been recently mechanically ventilated. Our primary hypothesize is that sedatives and neuromuscular blocking agents given in the ICU prior to extubation and during the first night following extubation are associated with sleep-disordered breathing. The secondary hypotheses are that duration of mechanical ventilation, BMI, and muscle strength are associated with sleep-disordered breathing during the night after extubation. The secondary objective is to evaluate if sleep-disordered breathing in the ICU can be predicted by standard pulmonary function testing in the ICU.
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.
The patients with sepsis are in high risk of malnutrition, which could contribute to infection, difficulty in weaning from ventilators. The investigators speculate whether nutrition therapy with high nitrogen could attenuate the malnutrition status and improve the outcome in these sepsis patients. In this prospective Randomized Controlled Trial, the investigators aim to compare high nitrogen intake with conventional nitrogen supply which were recommended in guidelines.
