Filter by:Patients over the age of 65 years are at increased risk for developing delirium and cognitive complications in the immediate postoperative period after noncardiac surgeries, resulting in increased morbidity and mortality. Previous small studies have shown beneficial effects of desflurane on postoperative cognitive recovery, which has been explained by the more rapid onset and offset of anesthesia as compared to sevoflurane. However, there are very limited data on the effect of desflurane on postoperative recovery and time until criteria for discharge from post-anesthesia care unit (PACU) are fulfilled in elderly patients undergoing minor-to moderate-risk noncardiac surgery. Therefore, the investigators will test the primary hypothesis that general anesthesia with desflurane significantly reduces the time between discontinuation of volatile anesthetics after the end of surgery and reaching ready for discharge from PACU criteria, which are defined as reaching a modified Aldrete score ≥ 12, as compared to sevoflurane in patients ≥ 65 years of age undergoing minor-to moderate-risk noncardiac surgery.
In the PATHFINDER 2 trial, the study investigators will test the intraoperative EEG-guided multimodal general anesthesia (MMGA) management strategy in combination with a postoperative protocolized analgesic approach to: 1. reduce the incidence of perioperative neurocognitive dysfunction in cardiac surgical patients 2. ensure hemodynamic stability and decrease use of vasopressors in the operating rooms 3. reduce pain and opioid consumption postoperatively
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.
To determine whether continuous theta burst stimulation can cure postoperative delirium in senior patients.
There is lack of attention to preoperative cognitive function and delirium in elderly who underwent surgery. The investigators are investigating different tools that can help to screen for cognitive dysfunction and delirium in the future.
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, and the incidence of POD after deep brain stimulation(DBS) implementation ranges from 10% to 40%. Previous studies suggested that aging and existing non-motor symptom were independent risk factors for POD after supratentorial tumor resections. Therefore, patients undergoing DBS are high-risk populations for POD. A lot of trials show that dexmedetomidine might help to reduce the incidence of delirium in patients undergoing non-cardiac surgery. However, the impact of dexmedetomidine on POD for patients undergoing DBS was seldom reported. The purpose of this study was to investigate the effect of dexmedetomidine on POD in patients with Parkinson' Disease undergoing DBS.
Surgery or trauma may cause serious problem to patients, especially for senile ones, like postoperative delirium or more postoperative complications. Here, we conduct a investigation of SFI for preventing the happening of POD or postoperative complications.
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.
