Treating Intraoperative Bradycardia in Non-cardiac Surgery Patients With Atropine at Heart Rates Below 60 Versus 30 Beats Per Minute and Norepinephrine Requirements

NCT06922097

CompletedNA

Sponsor: University of Hamburg-Eppendorf

Conditions: Intraoperative Bradycardia

Interventions: Giving atropine at heart rates below 60 beats per minute, Giving atropine at heart rates below 30 beats per minute

Countries: Germany

The RAPID trial is a randomized, single-center trial investigating whether giving atropine at heart rates below 60 beats per minute versus giving atropine only at heart rates below 30 beats per minute reduces the amount of norepinephrine needed to keep MAP above 65 mmHg in non-cardiac surgery patients with intraoperative bradycardia.
