ObjectivesTo compare the effects of intranasal dexmedetomidine (DEX) and DEX-ketamine (KET) on hemodynamics and sedation quality in children with congenital heart disease.DesignA randomized controlled, double-blind, prospective trial.SettingA tertiary care teaching hospital.ParticipantsThe study comprised 60 children undergoing transthoracic echocardiography (TTE).InterventionsPatients were randomly allocated into the DEX group (group D [n = 30]) or the DEX-KET group (group D-K [n = 30]). Group D received 2 μg/kg of intranasal DEX; group D-K received 2 μg/kg of DEX and 1 mg/kg of KET intranasally.Measurements And Main ResultsThe primary outcome was the change in hemodynamics, measured using mean arterial pressure (MAP) and heart rate (HR). Secondary outcomes were onset time, wake-up time, and discharge time. No differences were found in mean arterial pressure or heart rate. The onset time was significantly shorter in group D-K than in group D (9.6 ± 2.9 minutes v 14.3 ± 3.4 minutes; p = 0.031). The wake-up time was longer in group D-K than in group D (52 ± 14.7 minutes v 39.6 ± 12.1 minutes; p = 0.017). The discharge time was longer in group D-K than in group D (61.33 ± 11.59 minutes v 48.17 ± 8.86 minutes; p < 0.001). No differences in hemodynamics were found between the 2 groups. Intranasal DEX was found to be as effective for TTE sedation as intranasal DEX-KET, with longer onset time and shorter recovery and discharge times.ConclusionNo differences in hemodynamics were found between the 2 groups. Intranasal DEX was found to be as effective for TTE sedation as is intranasal DEX-KET, with longer onset time and shorter recovery and discharge times.Copyright © 2020 Elsevier Inc.
