Trial Outcomes & Findings for The Pharmacology and Hemodynamics of Dexmedetomidine in Children With Congenital Heart Disease (NCT NCT00480740)

NCT ID: NCT00480740

Last Updated: 2015-06-26

Results Overview

Non-inferiority was shown when differences at steady-state (dexmedetomidine + sevoflurane) compared to baseline (sevoflurane alone) and its associated 95% confidence interval fell completely within the range of plus or minus 20%.The 95% confidence interval was normalized by subtracting the baseline values. Bispectral Index: monitors electroencephalographic and electromyographic parameters to monitor the depth of anesthesia.

Participant Flow

Patients were recruited from cardiology outpatient clinic. The study is anticipating to enroll 104 patients.

74 subjects assessed for eligibility, 9 were excluded; 12 did not meet inclusion criteria; 12 refused to enroll; resulting in 41 subjects enrolled
