Randomized Controlled Trial
Optimal doses of intranasal esketamine plus dexmedetomidine for sedating toddlers during transthoracic echocardiography: a prospective, double-blind, randomized trial.
Esketamine has unique advantages in combination with dexmedetomidine for sedation in young children, owing to its sympathetic activity and mild respiratory depression. However, the optimal dose is yet to be determined. In this study, we compared the different doses of intranasal esketamine combined with dexmedetomidine for sedation during transthoracic echocardiography in toddlers. ⋯ ChiCTR2200060976, 2022/06/14 (trail from August 2022 to January 2023).

Randomized Controlled Trial
Effects of Sub-Anesthetic Oro-Mucosal Dexmedetomidine on Sleep in Humans: A Randomized, Controlled Pharmacokinetics-Pharmacodynamics Study.
The locus coeruleus noradrenergic system may provide a potential new target for pharmacologic insomnia treatment, particularly in patients suffering from elevated distress. The selective α 2 -noradrenergic agonist dexmedetomidine attenuates locus coeruleus activity in subanesthetic doses, yet no adequate nonparental delivery systems of dexmedetomidine are currently available. To examine the feasibility of oromucosal dexmedetomidine administration, the authors developed two distinct-one sublingual and one buccal-oromucosal, fast-disintegrating dexmedetomidine formulas tailored for self-administration. Here, the authors established the formulas' pharmacokinetic and pharmacodynamic profiles. ⋯ The favorable pharmacokinetic and pharmacodynamic profile of oromucosal dexmedetomidine delivery warrants further dose-finding and clinical studies to establish the exact roles of α 2 receptor agonism in pharmacologic sleep enhancement and as a possible novel mechanism to alleviate stress-related insomnia.

Randomized Controlled Trial Comparative StudyComparison of plasma concentration and sedative effect of sublingual and intranasal dexmedetomidine in children: A double-blind randomised controlled study.
Pharmacokinetics and sedative effects of sublingual dexmedetomidine have not been established in children. The primary aim was to compare peak plasma concentration, time to reach peak plasma concentration and area under the curve with 2 μg/kg sublingual and intranasal dexmedetomidine. The secondary aims were to compare the depth of sedation, parental separation anxiety, mask acceptance, heart rate changes, analgesic requirements and recovery time with 2 μg/kg sublingual and intranasal dexmedetomidine in children. ⋯ This study compared the pharmacokinetics and sedative effects of sublingual versus intranasal dexmedetomidine in children, finding that intranasal administration resulted in significantly higher peak plasma concentration and faster time to peak concentration. Both routes achieved comparable sedation, parental separation anxiety scores and mask acceptance, with no significant adverse effects observed.

Review Meta Analysis Comparative Study
Postoperative delirium under general anaesthesia by remimazolam versus propofol: A systematic review and meta-analysis of randomised controlled trials.
Remimazolam, an ultra-short-acting benzodiazepine, has similar clinical effects to propofol for sedation in general anaesthesia. However, it remains uncertain whether remimazolam could increase postoperative delirium (POD) compared with propofol. ⋯ Perioperative remimazolam administration did not increase POD and reduced the risk of intraoperative hypotension compared to propofol. Further large-scale RCTs are warranted to explore the association of remimazolam and POD. Systematic review protocol: PROSPERO CRD42024544122.

Multicenter Study
The effect of intraoperative midazolam on postoperative delirium in older surgical patients: a prospective, multicentre cohort study.
Midazolam is a short-acting benzodiazepine frequently used in the perioperative setting. This study aimed to investigate the potential impact of intraoperative midazolam on postoperative delirium in older patients undergoing noncardiac surgery. ⋯ Intraoperative administration of midazolam may not be associated with an increased risk of postoperative delirium in older patients undergoing noncardiac surgery.
