Filter by:This prospective study aims to evaluate the effectiveness of intraoperative DEX for postoperative analgesia and recovery after non-intubated VATS. In addition, the investigators observe the impact of DEX on anesthetic requirements, hemodynamic parameters, and adverse events during non-intubated VATS.
The aim of this study will be to compare the effects of morphine versus dexmedetomidine when used as adjuvants to local anesthetic (Ropivacaine) in Erector Spinae Plane Block under ultrasound guidance. A group without an adjuvant will also be compared to the groups.
Sleep disturbances are prevalent in older patients with osteoarthrosis or fracture scheduled for knee or hip replacement surgery. The occurrence of sleep disturbances is associated with worse outcomes including increased risk of delirium and cardiac events, and worsened functional recovery. Dexmedetomidine is a highly selective α2-adrenergic agonist with sedative, anxiolytic, and analgesic properties. It exerts sedative effects via activating the endogenous sleep pathways and produces a state like non-rapid eye movement sleep, which is different from opioid- and benzodiazepine-induced sedation. Night-time infusion of low-dose dexmedetomidine may improve sleep quality. However, evidence in this aspect is limited.
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.
Studies have shown that the use of dexmedetomidine before and during surgery has a good sedative, analgesic and circulatory stabilizing effect. The use of dexmedetomidine in thoracoscopic lung resection has been proven to be safe and feasible, and it has a certain degree of improvement in postoperative lung function. Combining the advantages of thoracoscopy and the previous experience of combined acupuncture and drug anesthesia technology, our team pioneered cardiopulmonary surgery without endotracheal intubation and combined needle and drug anesthesia, so that the patient was in a state of light sleep and spontaneous breathing without tracheal intubation. After completing the operation, it was found that this technical method can effectively reduce the amount of intraoperative anesthetics, improve intraoperative lung ventilation, improve lung oxygenation, achieve intraoperative organ protection, and significantly reduce complications caused by tracheal intubation , Postoperative analgesic drugs have reduced the amount of 20%, accelerate the time of exhaust and defecation, and its postoperative rehabilitation is better than conventional treatment. These results suggest that the combination of acupuncture and medicine is not only suitable for anesthesia, it can be used scientifically and rationally in postoperative analgesia, immune regulation and even the entire perioperative organ protection, creating more possibilities for patients' ERAS. In combined acupuncture and drug anesthesia, the core goal is to use acupuncture to reduce the insufficiency of anesthetics in terms of analgesia, sedation, stable circulation, and protection of organs. However, the mechanism of action behind this type of combination has not yet been improved. Efficacy kinetics or pharmacokinetics has been explained convincingly, or it is not well recognized. For example, is there a specific target in the body of acupuncture? If there is a specific target, where is the effect target? If the combined application of acupuncture and medicine produces a synergistic effect through a pharmacokinetic mechanism, its specific mechanism still needs to be clarified.
This study will investigate the effect of dexmedetomidine on the incidence of postoperative acute kidney injury in patients undergoing EVAR under general anesthesia
The hypothesis is whether perineural dexamethasone and dexmedetomidine prolonged the duration of analgesia as compared with either perineural dexamethasone or perineural dexmedetomidine after TPVB.
This study is to evaluate The analgesic effect of intrathecal versus intravenous dexmeditomedine in transurethral resection of the prostate
A continuous infusion of Dexmedetomidine (DEX) will be administered to 80 patients admitted to Critical Care because of signs of Respiratory Insufficiency requiring non-invasive ventilation. Measurements of respiratory performance and quantification of cellular and molecular inflammatory mediators. The primary outcome will be the avoidance of mechanical ventilation with secondary outcomes duration of mechanical ventilation, avoidance of delirium after sedation and association of mediators of inflammation to outcomes. Outcomes will be compared to a matched historical control (no DEX) series
The brain protection effect of dexmedetomidine has been approved in several studies. Basically, the anti-inflammatory effects and reducing catecholamines are thought to be a main role of the protection effect. In many studies reported the advantage of dexmedetomidine as a substitution of other sedative drugs for anesthesia. The anesthesia of intra-cranial aneurysmal clipping operation commonly use intravenous anesthetic agents combined with inhalation anesthesia for neuroprotection, and mostly propofol is used. The aim of this study is to examine the effects of dexmedetomidine on serum inflammatory markers and research the hemodynamic stability of dexmedetomidine compared to propofol in aneurysmal clipping operation.
