However, the optimal anesthetic\u002Fsedation plan has not been determined for these procedures. Historically, common medications have included the use of pentobarbital and propofol, but in 2015, publication in the New England Journal of Medicine highlighted the accumulating evidence for the possible neurotoxic effects of these types of anesthetics in animal models and a collection of epidemiologic studies in humans. Although these initial possibilities have since been proven as less of a concern, in the interim, data has shown that alternative sedative agents, such as dexmedetomidine, may not have the same neurotoxic effect and could possibly even provide neuroprotection. Dexmedetomidine also possesses other beneficial traits such as reducing risks of pulmonary atelectasis or upper airway collapse, typically found with the administration of propofol.\n\nA concern raised by previous studies has been the possibility that the addition of dexmedetomidine could increase recovery times, leading to disruptions in workflow. Although it has been shown that large doses of dexmedetomidine exposure may lead to longer PACU stays, it is uncertain whether a small dose of dexmedetomidine would have such a significant impact. Based on the investigators' pilot trial6, the investigators found that a bolus of 1 mcg\u002Fkg dose of dexmedetomidine with a bolus of titrated propofol of 2-3 mg\u002Fkg and an infusion of propofol of 100 mcg\u002Fkg\u002Fmin provided adequate sedation for successful scans, reduced propofol (infusion) exposure by 60%, and did not significantly increase recovery times.\n\nFinally, there is a paucity in literature for studies examining a range of doses subsequently; often, a control group is compared to a single, self-selected dose of choice. Here, the investigators hope to provide a range of doses to minimize selection bias in our study design and determine the dose that would provide the optimal sedation for these scans and minimize excess anesthetic exposure.",[27,28,29,30,31,32],"MRI Sedation","Pediatric Sedation","Propofol Dosage","Emergence Delirium, Anesthesia","Recovery Time","Dexmedetomidine",[34,35,36,37,38],"pediatrics","sedation","dexmedetomidine","propofol","MRI","RECRUITING","2026-05-27",{"date":42,"type":43},"2026-05-29","ACTUAL",{"date":45,"type":21},"2026-06",{"date":47,"type":21},"2028-03",{"name":49,"class":50},"Boston Children's Hospital","OTHER",1,{"id":53,"slug":54,"hasResults":11,"nctId":55,"briefTitle":56,"officialTitle":57,"acronym":4,"eligibilityCriteria":58,"healthyVolunteers":11,"sex":16,"minAge":59,"maxAge":4,"enrollmentInfo":60,"targetDuration":4,"studyType":22,"phases":62,"briefSummary":64,"conditions":65,"keywords":74,"overallStatus":39,"whyStopped":4,"lastUpdateSubmitDate":78,"lastUpdatePostDateStruct":79,"startDateStruct":81,"completionDateStruct":83,"leadSponsor":85,"locationsCount":51},"100635703","dexmedetomidine-and-propofol-for-sedation-in-cataract-surgery-100635703","NCT07556133","Dexmedetomidine and Propofol for Sedation in Cataract Surgery.","Dexmedetomidine vs Propofol for Sedation in Cataract Surgery : a Prospective Randomized Controlled Trial.","Inclusion Criteria:\n\n* Adults undergoing cataract surgery\n\nExclusion Criteria:\n\n* Severe hepatic insufficiency\n* Third degree AV block\n* Patient refusal","18 Years",{"count":61,"type":21},1000,[63],"NA","The goal of this prospective, randomized, single-blinded is to learn if there is an ideal sedation protocol in cataract surgery in adults.\n\nThe main questions it aims to answer are:\n\n* Does the combination of Dexmedetomidine and Propofol affect significantly Ramsay sedation scale, compared to Dexmedetomidine and compared to Propofol?\n* How does each sedation protocol affect hemodynamics?
