Filter by:The aim of this study is to compare the analgesic effects of different doses of dexmedetomidine as an adjuvant in external oblique intercostal plane block (EOIPB) in splenectomy.
Dexmedetomidine is a selective α -2 agonist widely used in anesthesia for its sympatholytic, sedative and analgesic effects . Favorable respiratory effects in animals , and in selected human patient groups have been reported when using this agent .we investigated the effects of different doses of dexmedetomidine infusion on oxygenation
The aim of this study is to evaluate the role of intraoperative dexmedetomidine infusion in endovascular intervention for aneurysmal subarachnoid hemorrhage.
The aim of this study is to compare the role of dexmedetomidine and ketamine as an adjuvant in external oblique intercostal plane block for post thoracotomy pain.
Dexmedetomidine bolus dose may provide similar or less hemodynamic changes (less bradycardia and less hypertension) than infusion dose during induction of anaesthesia and tracheal intubation.
The aim of this study is to compare the analgesic effect of bilateral US-guided ESPB using bupivacaine alone versus bupivacaine and DEX in lumbar fusion surgeries.
in our study, we will investigate the impact of adding dexmedetomidine to bupivacaine for the potency of the obturator nerve block and prevention of the postoperative pain associated with transurethral surgery in comparison of obturator nerve block with bupivacaine alone
The objective of this study is to evaluate the effect of adding dexmedetomidine on evoked potentials in adult patients undergoing spinal surgery under intravenous anesthesia
Studies have shown that intravenous infusion and nebulized dexmedetomidine can improve lung function in mechanically ventilated patients, including those with preoperative COPD, exerting lung protection. However, these studies are based on mechanical ventilation patients under general anesthesia, and more intuitive research is needed on whether dexmedetomidine can also exercise pulmonary precaution in awake patients. Pulmonary function monitoring is the most direct way to evaluate changes in lung function in awake patients. Portable pulmonary function machines can assess lung function in a variety of settings. In addition, compared with intravenous administration, nebulized inhalation administration directly acts on the mucosa of the respiratory tract, does not involve invasive operations, and has higher safety and comfort. Therefore, this study intends to use portable pulmonary function instruments and non-invasive ambulatory respiratory monitors to evaluate the effect of nebulized dexmedetomidine on lung function in COPD patients to guide the perioperative management of COPD patients.
Perioperative anesthesia can affect postoperative cognitive function. In our previous study, intraoperative dexmedetomidine (Dex) infusion reduced the incidence of delirium within the first 5 days after brain tumor. However, the mechanism is still unclear. With the development of neuroimaging, multimodal neuroimaging technology provide a new method to explore the underlying mechanism. Therefore, the purpose of this study is to analyze the alterations of brain network under sedation and anesthesia by different anesthetics in patients with supratentorial glioma and their association with cognition.
