Filter by:Lumbar vertebra surgery is one of the most common surgical procedures.Delirium is common in geriatric patients after lumbar spinae surgery.postoperative delirium usually occurs in the early postoperative period and delays patient mobilization and thus lengthens hospital stay. The aim of this study was to investigate the effect of this field block on postoperative delirium in patients undergoing ESP with lomber vertebra surgery and with ultrasound guidance for postoperative analgesia.
Postoperative delirium (POD) is a common and distressing complication after thoracic surgery. S-ketamine has neuroprotective properties as a dissociative anesthetic. Emerging literature has indicated that S-ketamine can reduce cognitive impairment in depressed patients. However, the role of S-ketamine in preventing postoperative delirium is still unknown. Therefore, this study aims to evaluate the effect of intraoperatively prophylactic S-ketamine compared to dexmedetomidine on the incidence of postoperative delirium in elderly patients undergoing non-cardiac thoracic surgery.
Postoperative delirium (POD) is a common perioperative complication, which can lead to adverse outcomes. Patients undergoing carotid endarterectomy (CEA) were elderly, complicated with vascular risk factors, cognitive dysfunction, some also had a history of stroke, and the circulation fluctuated greatly during the operation, often resulting in hypoperfusion of cerebral tissue and hypoxia. Therefore, they're the high-risk group of POD. Near-infrared Spectroscopy (NIRS) can continuously and noninvasively monitor local cerebral oxygen saturation (SctO2) to identify the mismatch of oxygen supply and demand in brain tissue. However, for CEA patients, the association between intraoperative SctO2 changes and POD remains unclear. This study intends to explore the association between them and determine the SctO2 threshold for predicting POD. We will monitor SctO2 intraoperatively, follow up and collect data postoperatively.
Postoperative delirium (POD) is a common complication in elderly patients and is associated with negative clinical outcomes, such as prolonged hospitalizations, cognitive impairment, and higher mortality rate. While the pathophysiology of delirium remains unknown, the cerebral hypoperfusion and neuroinflammatory response are considered to play an important role in the process of POD. The aim of the study is to determine the association between POD and biomarkers in elderly patients undergoing noncardiac and non-neurological surgery.
Postoperative delirium (POD) is a common surgical complication. The incidence is 10% to 22% in neurological procedures, and advanced age is a risk factor for neurological procedures. Many studies have shown that dexmedetomidine(DEX) may reduce the incidence of delirium in non-cardiac surgery patients and elderly patients. However, there are few studies focus on the effect of DEX on POD in elderly patients undergoing neurosurgery. The purpose of this study was to investigate the effect of DEX on POD in in elderly patients undergoing craniotomy.
Postoperative delirium is common and associated with significant adverse outcomes. Its etiology is unknown, and little is known about associated risk factors. The investigatorea aim to test whether providing emotional and orientation support can reduce the risk of postoperative delirium in elderly patients undergoing elective non-cardiac surgery. Specifically, the investigators will test whether allowing such patients to keep their hearing and visual aids and be escorted into the operating room by a family member until anesthesia induction reduces the incidence of postoperative delirium. Delirium will be actively screened as part of our institution's clinical practice starting at PACU admission and for a minimum of 2 postoperative days. The investigators will use a multiple cross-over design to enroll all eligible patients and alternate between the intervention and our common practice (removing sensorial aids in the preoperative area and not allowing patients' escort beyond that point) every 2 weeks for up to 2 years.
An investigation of the change in inflammation marker levels across hip fracture surgery and an exploration of any association with change in self reported health status and incidence of postoperative delirium
Patients undergoing cardiac surgery often complain of anxiety before a major operation and the resulting stress. This circumstance is a risk factor for mental problems that may occur after the operation (e.g., delirium or memory deficits). This study aims to prevent these discomforts by a preoperative relaxation intervention.
Postoperative delirium is one of the most frequent adverse events following elective non-cardiac surgery and is associated with cognitive impairment at discharge, as well as in-hospital and long-term mortality, however, despite being a well-recognized problem there is a dearth of effective interventions for prevention and management. A modifiable risk factor associated with postoperative delirium is poor postoperative pain control, and by improving the pain regimen the investigators may be able to decrease the incidence and/or severity of postoperative delirium. In this study, the investigators seek to study whether a postoperative intravenous infusion of lidocaine, known to improve pain control in other contexts, can decrease the risk of postoperative delirium and other opioid-related side effects, following major reconstructive spinal surgery.
The purpose of this study is to explorethe brain excitability in patients undergoing heart valve replacement surgery with cardiopulmonary bypass and the correlation with postoperative delirium
