Filter by:The aim of the present study is to assess the effect of postoperative remifentanil infusion on the incidence of emergence agitation in preschool-aged children undergoing strabismus surgery with sevoflurane anaesthesia.
It is well known that ICU patients need sedation. Now no ideal sedation drug existed and every sedation drug has its advantage and disadvantage,so combined sedation may use the advantage and avoid the disadvantage of the sedation drug according to the patients'condition. Until now, there is rare study about the combined sedation or sequenced sedation of different sedation drug.The purpose of the study is to explore the value of combined sedation with midazolam and dexmedetomidine compared to single drug sedation in ICU, so as to seek an ideal sedation protocol that could reduce the cost of treatment,obtain the appropriate sedation not under sedation or over sedation,reduce the incidence of delirium, reduce the adverse event of sedation.
to evaluate the incidence of delirium in patients with acute coronary syndrome and its correlation with adverse events
Objective: Delirium is an important and frequently occurring complication in intensive care patients. However, screening and treatment of delirium is not in accordance with current national and international guidelines. The first objective of this prospective study is to describe the barriers and facilitators for guideline adherence. Second, investigators will develop a tailored implementation strategy. Finally, investigators will describe the effects of the tailored implementation on the adherence of the guideline in a pilot study. Design: Current practices, attitudes and deviations from a national (Dutch) delirium guideline will be assessed in a prospective before-measurement. Barriers and facilitators will be identified with surveys and focus group interviews. Adherence to the guideline will be studied in a before-after study in 7 ICUs in the Southwest of the Netherlands. Further, the effect of a multifaceted implementation strategy-guided implementation will be assessed with regard to important clinical outcomes, such as mortality and delirium incidence. Population: Professionals (Physicians/intensivists, nurses' and psychiatrists) and ICU patients. Intervention: The delirium guideline of the Netherlands Society of Intensive Care (NVIC) is implemented in this study. Implementation strategies: Barriers and facilitators will be determined in focus group interviews (n=7) with health care professionals resulting in a tailored guideline implementation strategy. In the development of the strategies specific attention will be paid to sustaining the guideline adherence. Main outcome: 1. Current practices; 2. Barriers and facilitators for guideline adherence; 3. Tailored implementation strategy; 4. Percentage of adherence to the guideline (early screening, prevention and treatment of delirium); 5. Effects of implementation on outcomes (economic, mortality, delirium incidence). Data analysis / power: The main effects, guideline adherence, will be evaluated by comparing the before and after measurements. Calculating from 90% power,2-sided alpha=0.01, 231 patients per periods will be sufficient to test the proposed adherence of 85%. Economic evaluation: The economic analysis will be performed from a health care perspective. Investigator will calculate and compare the direct medical costs of usual care (before) and care after implementation of the guideline. Additionally, the cost of the tailored guideline implementation process will be calculated. The economic analysis will be a cost-minimalization analysis.
Cerebral desaturations occur frequently in patients undergoing non-cardiac surgery. The definition of what constitutes a cerebral desaturation, the incidence of the phenomenon, the association between desaturations and perioperative outcome, and the mechanistic explanations of cerebral desaturations remain unexamined. This study seeks to identify the true incidence and magnitude of cerebral desaturations in high-risk non-cardiac surgical patients and the association between desaturations and perioperative outcome. The investigators will attempt to determine the following (1) The proper definition, incidence and severity of decreased cerebral saturation (rSO2) in high-risk non-cardiac surgical patients (2) the mechanisms surrounding decreases in rSO2 by correlating it with alterations in physiologic parameters (such as blood pressure, cardiac output, hemoglobin concentration, and carbon dioxide levels) and (3) to correlate the incidence and severity of decreased rSO2 with relevant perioperative. The investigators will also analyze a panel of inflammatory biomarkers to determine if these biomarkers have the ability to predict postoperative complications. The investigators will study 200 high-risk patients undergoing high-risk non-cardiac surgery. The investigators will determine the incidence and severity of decreases in rSO2, the associated factors with the occurrence of decreased rSO2, and the relationship between decreases in rSO2 and adverse perioperative outcome with a composite of well defined perioperative complications such as death, myocardial infarction, cerebrovascular accident, acute kidney injury, delirium, postoperative infections, and the need for mechanical ventilation.
The purpose of this study is to find out if using bright light sessions during bone marrow transplant can prevent people from developing confusion also known as delirium.
The typical delirium study between 1989 and 2005 compared delirium management in a specialty unit such as geriatric medicine with delirium management in general medicine (in most cases the research diagnosis of delirium was not communicated to the general medicine group). This study will provide open diagnosis of delirium by the CAM to both the geriatric medicine and general medicine groups (medical staff, patients, families) plus daily monitoring of delirium using digit span and delirium index which is reported to both patient groups. It will also compare confusion assessment method (CAM)to a novel diagnostic system of Paul Regal with respect to hard endpoints (survival and return home). Hypotheses: 1) General medicine can manage delirium as well as geriatric medicine when delirium is openly diagnosed and monitored daily (even in speciality units it is rare to find daily measurement of tools such as delirium index); 2) The Regal diagnostic system will be superior to the CAM in predicting hard endpoints (survival and return home rate for patients living in the community).
A study will be conducted to determine if there is any cognitive benefit in elderly patients having open versus minimally invasive colon cancer surgery.
Our purpose of this study is to determine whether bright light therapy is effective for reducing the incidence and the duration of delirium compared to the usual treatment in patients at the Intensive Care Unit. Our hypothesis is that bright light therapy is effective for reducing the incidence and duration of delirium in patients at the Intensive Care Unit Patients will be assigned to a chamber with or without bright light therapy. This assignment is based on occupation of ICU beds and availability of nurses and is therefore independent from patients characteristics. Patients will be included following the inclusion criterion and exclusion criteria. Patients assigned to a chamber with bright light therapy will receive light therapy for three hours in the morning, from eight o'clock till eleven o'clock. The Confusion Assessment Method-score (CAM-score) and the Richmond Agitation Sedation Scale-score (RASS-score) will be performed three times at one day by ICU nurses, this is according to the existing routine. Besides this, an extra CAM-score and a clinical assessment will be performed once a day by a trained non-clinician, to determine the presence of delirium. The use of sedatives, haldol and fixation will be registered to determine the occurrence, duration and severity of delirium. Eventually the most important outcomes will be the clinical assessment of the patients, the CAM-score and the use of haldol. The primary outcome of this study is the duration of delirium, defined in number of days.
Postoperative agitation (hyperactive delirium) is common following major surgery(incidence was about 20% in our pilot study). Dexmedetomidine was related to a reduced delirium rate when comparing with midazolam in many clinical settings. It is not clear if dexmedetomidine is useful on reducing postoperative delirium. The hypothesis of present study: intraoperative application of dexmedetomidine (0.2ug/kg/h) is is effective (50% reduce) than placebo for reducing of early postoperative delirium and increase postoperative quality of recovery within 24 postoperative hours.
