Active clinical trials for "Emergence Delirium"

Delirium are common after orthopedic surgery in the elderly and are directly associated with loss of independence, reduction in the quality of life and increased mortality. The cause of postoperative delirium still remains unclear and may be multifactorial. The aim of this retrospective study is to examine prevalence of postoperative delirium according to the use of dexmedetomidine or propofol in elderly patients undergoing orthopedic surgery under regional anesthesia.

The purpose of this study is to determine the incidence, long term outcome and factor related to postoperative delirium in elderly patients after non-cardiac surgery.

To explore the correlation between tear metabolomics and POD. The purpose of this study was to compare the results of tear metabolomics between POD and non-POD elderly patients undergoing abdominal surgery, to clarify the correlation between tear metabolomics and POD, and to find tear markers related to POD.

Preoperative cognitive impairment (PCI) may increase the incidence of postoperative delirium (POD), yet screening for cognitive impairment is rarely performed. This study hypothesized that Mini-Cog for preoperative cognitive impairment screening predicts postoperative delirium. Elderly patients (65 years or older) attending Henan Provincial People's Hospital during the trial period who required elective thoracic surgery were recruited into the study.

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.

The aim of this study is to compare the risk factors and the incidence of delirium following orthopedic surgery under the general or regional anesthesia in elderly patients.

This study investigates electrical acupoint stimulation (EAS) administered in peri-operation for improving postoperative recovery in elder patients, who accept knee arthroplasty. the surgery cause to change of stress response, which might be associated with postoperative recovery of patient Totally, three groups are created, 1/3 participants receive transcutaneous electrical acupoint stimulation, 1/3 participants receive electroacupuncture, the rest 1/3 will use sham transcutaneous electrical acupoint stimulation.

Emergence agitation (EA) is highly prevalent in children after surgery. Risk factors for EA are Eye, nose and throat (ENT) surgery, preoperative anxiety, postoperative pain. There are several preventive strategies but none of them completely prevent EA. Topical application of ropivacaine can reduce post-tonsillectomy pain. Therefore, it might reduce the incidence of postoperative EA.

The purpose of this research is to study pre-operative sleep problems and delirium in Hispanic/Latino patients after heart and lung surgery.

Delirium is known to be one of the most common postoperative complications in elderly patients undergoing surgery. Because postoperative delirium can affect the length of hospital stay and prognosis significantly, it is important to identify the risk factors for postoperative delirium in advance. However, there have been few reports concerning intraoperative modifiable risk factors, such as postoperative pain, for postoperative delirium.
