Filter by:Delirium, an acute change in mental status, is a serious medical complication among hospitalized patients. Syndrome of delirium involves agitation, sleep disturbance, affective disorders and cognitive disruptions. One vulnerable period for developing delirium is in the postoperative days. Postoperative delirium often initiates a cascade of adverse consequences including an increase in length of stay and hospital costs, and greater mortality. The investigators have observed that the incidence of postoperative delirium in patients after renal transplantation is about 20-30% in our hospital. Several studies have revealed that dexmedetomidine, as a widely used sedative during anesthesia, can decrease the incidence of postoperative delirium after cardiac surgery. The investigators aim to examine whether administration of dexmedetomidine can reduce postoperative delirium after living donor renal transplantation in adult patients.
Emergence delirium which is a phenomenon seen commonly in preschool kids anesthetized with Sevoflurane. Restless recovery from anesthesia may not only cause injury to the child or to the surgical site, but may also lead to the accidental removal of surgical dressings, IV catheters, and drains. is one of the The purpose of the study is to find whether duration of exposure to Sevoflurane has any effect on the incidence of Emergence Delirium.
The purpose of the study is to determine the relationship between the degree of neuromuscular block, the release of cytokines and clinical outcomes in elderly patients undergoing orthopedic surgery. Investigators hypothesize that deep neuromuscular blockade decreases the release of cytokine and the incidence of postoperative delirium in elderly patients undergoing orthopedic surgery, compared with moderate neuromuscular blockade.
The purpose of this study is to determine whether the incidence of emergence delirium will be reduced when end-tidal concentration of sevoflurane decreases.
The study is a substudy of the Enigma2 trial (NCT00430989) which aims at investigating the effectiveness and safety of nitrous oxide (N2O) in anaesthesia.The substudy focus is on postoperative cognitive disorders. Substudy Hypothesis: In patients undergoing anaesthesia for major surgery, administration of N2O will reduce postoperative cognitive disorders when compared with otherwise identically managed surgical patients not receiving N2O as a component of their anaesthesia.
The investigators hypothesize that critical care trained registered nurses and physicians can perform measurements of cognitive impairment in critically ill pediatric patients in a reliable and valid manner. To test this hypothesis, the investigators will incorporate an instrument (psCAM-ICU) to assess both components of consciousness, arousal and content, in critically ill pediatric patients at least 6 months to children 5 years of age, both on and off mechanical ventilation, and compare these assessments to those of the reference standard.
Postoperative delirium is an important problem in patients undergoing major cardiac surgery and associated with more complicated hospital course, increased hospital length of stay and total postoperative cost. A study shows that a low preoperative cerebral oximetry (rSO2) is associated with postoperative delirium after on-pump cardiac surgery. Another study showed that patients who underwent cardiac surgery with reduced cerebral blood flow (CBF) velocity in the left middle cerebral artery (MCA) preoperatively are at greater risk for postoperative cognitive dysfunction (POCD). Therefore, the investigators hypothesize that lower perioperative rSO2 and reduced preoperative mean flow velocity (MFV) of MCA are good predictors of the postoperative delirium in the patients undergoing the on-pump cardiac surgery.
This study is developed for assessing the pharmacodynamic and pharmacokinetic properties of intravenous (IV) clonidine in critically ill patients on the ICU, and to estimate the optimal dosing strategy for IV clonidine.
Delirium, as a common complication of hospitalization, poses significant health problems in hospitalized patients. Though about a third of delirium cases can benefit from intervention, detecting and predicting delirium is still very limited in practice. A common characterization of delirium is change in activity level, causing patients to become hyperactive or hypoactive which is manifested in facial expressions and total body movements. This pilot study is designed to test the feasibility of a delirium detection system using movement data obtained from 3-axis wearable accelerometers and commercially available camera with facial recognition video system in conjunction with electronics medical record (EMR) data to analyze the relation of whole-body movement and facial expressions with delirium.
The purpose of this study is to find out whether postoperative delirium can be more properly prevented by the combination of determined preventive agents in past studies. Further on the investigators measure pre- and postoperative cortisol, neuron specific enolase (NSE) and S-100beta levels.
