Abstract

BackgroundDexmedetomidine (DEX) is an alpha-2 adrenergic drug used for short sedation and as an alternative to diazepam (DZP) in the treatment of alcohol withdrawal syndrome (AWS). PurposeThis study aims to compare the hemodynamic effect of DZP versus DEX on heart rate (HR) and blood pressure in patients with AWS. MethodsProspective randomized clinical trial that includes 40 patients with AWS from Mérida, Yucatán, México. ResultsForty patients were randomly divided into two groups: one group DZP (n=20) patients received diazepam (doses 5–20mg IV) and the other group (n=20) received DEX (dexmedetomidine infusion .2–.7mcg/kg/min). We obtained statistical significance in sedation with the DEX group in the degree of traumatic brain injury I/II (p=.003). The DEX group remained haemodynamically stable in the first 24h, the mean HR (73.85±8.39) was significant comparing both groups (p=.002). In the comparison of the figures for the DEX group with the DZP (143.85±2.30–137.95±5.62) the SBP was significant with a (p=.0001). Furthermore, DEX treatment was shorter. ConclusionAlthough DEX is not indicated for the routine treatment of AWS, this study proposes a positive effect on HR, SBP and fewer days of treatment compared to the standard DZP treatment for AWS.Clinical Trials.gov ID: NCT03877120—https://clinicaltrials.gov/ct2/show/NCT03877120.
