Study: NCT06257316

Intervention type: DRUG
Group type: ACTIVE_COMPARATOR
Intervention: EPHEDrine Hydrochloride 5 mg/ml
Description: In the present study, the expected rate of recovery of the internal carotid artery according to the dose of the inotropic agent was similar to that in a previous study in which the fraction maintaining mean arterial pressure within 80% of baseline by dose of inotropic agent was 0.9% for the ephedrine 0.1, 0.6, 0.8, 1. 0, 1.2, and 1.4 doses (mg/kg) were 9.9%, 21%, 41%, 47%, 65.5%, and 40%, respectively (Br J Anaesth. 2023 May;130(5):603-610), and it was assumed that the rate of internal carotid artery recovery by inotrope dose would be 90% of that result.~The study will randomize to dose in six cohorts and will include dose group and cohort variables in a logistic regression model to assess the trend between inotropic dose and rate of carotid revascularization after correcting for cohort effects on the outcome variable.
