Filter by:This study is a multicenter, prospective, randomized controlled clinical trial that aims to observe the impact of Transcutaneous Electrical Acupoint Stimulation (TEAS) on plasma TK/MMP3 in a randomized controlled setting. The intervention group received percutaneous acupoint electrical stimulation, whereas the control group underwent conventional treatment. The primary objective is to enhance the management of postoperative delirium, specifically focusing on the occurrence and severity of delirium following thoracoscopic pulmonary resection. Additionally, various perioperative inflammatory markers, cognitive function, recovery quality, pain levels, anxiety, sleep patterns, postoperative complications, and overall hospital stay duration were monitored to elucidate the mechanisms through which percutaneous acupoint electrical stimulation improves postoperative delirium.
This study aims to investigate the incidence of postoperative delirium (POD) in the PACU and analyze its influencing factors, in order to provide theoretical basis for early screening and intervention for high-risk POD population. Blood samples of some study subjects will be collected and analyzed using molecular detection methods to provide a basis and insights into the pathophysiological mechanisms of POD.
Investigating postoperative delirium in patients undergoing thoracoscopic lung resection surgery who have received or not received relevant transcutaneous acupoint electrical stimulation treatment preoperatively, observing postoperative recovery quality indicators, evaluating the necessity of treatment, and clarifying the potential mechanisms by which transcutaneous acupoint electrical stimulation may improve postoperative delirium.
Postoperative delirium (POD) is the most common complications (~50-60%) in elderly and major challenges to our rapidly growing aging population. Growing evidence suggests a possible role for neuroinflammation in the development of delirium, which is facilitated by a transient increase in blood-brain barrier (BBB) permeability. Lidocaine and dexmedetomidine, commonly used anesthetic adjuncts, have anti-inflammatory properties. Both drugs are reported to have modulatory effect on the intergrity of BBB and associated with a beneficial effect on postoperative neurocognitive dysfunction. In this regard, The investigators aimed to prospectively compare the modulatory effect of the intraoperative administration of dexmedetomidine or lidocaine with a sham control group (normal saline solution) on surgery-induced BBB disruption.
The goal of this prospective cohort study is to assess potential differences in sleep biomarkers in older adult patients undergoing major orthopedic surgery. The main questions it aims to answer are: 1. To define sleep/circadian biomarkers of delirium (sleep duration, regularity, stability and timing of rhythm) in a prospective observational study. 2. To determine if plasma Alzheimer's disease (AD) pathology/inflammatory burden interacts with or moderates the relationship between a sleep/circadian biomarker and post-operative delirium (POD) risk. 3. To determine whether sleep/circadian regulation interacts with the genetic risk of AD to influence POD/cognitive decline. Participants will be asked to: 1. Donate several blood samples both intraoperatively and postoperatively 2. Complete baseline and postoperative neurocognitive assessments 3. Wear an actigraphy data collection watch for the two weeks prior to their surgery
Although the incidence of delirium after cardiac surgery is high, it is not sufficiently recognized. The long-term effects of delirium are likely to be underestimated. In this study, the investigators aimed to examine the relationship between optic nerve sheath diameter and postoperative delirium in open hearth surgery.
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.
