Summary

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.

Conditions

  • Intraoperative Bradycardia

Interventions

DRUG

Giving atropine at heart rates below 60 beats per minute

In patients assigned to the atropine therapy at heart rates below 60 beats per minute, atropine will be given at a dose of 0.5 mg when heart rate is below 60 beats per minute for one continuous minute. A second and third atropine dose of 0.5 mg will be given if heart rate remains or again drops below 60 beats per minute for one continuous minute. Patients will not be given more than 1.5 mg atropine.

DRUG

Giving atropine at heart rates below 30 beats per minute

In patients assigned to atropine therapy at heart rates below 30 beats per minute, atropine will be given at a dose of 0.5 mg when heart rate is below 30 beats per minute for one continuous minute. A second and third atropine dose of 0.5 mg will be given if heart rate remains or again drops below 30 beats per minute for one continuous minute. Patients will not be given more than 1.5 mg atropine.
