You are performing an epidural on a patient in labor. As you begin to administer your test dose you see pts heart rate go up. She is now breathing deeply and rubbing her stomach. Is it OK to proceed?
No, elevated HR is a sign of intravascular injection. Stop injection.
Elevated HR is an expected side effect and It is OK to proceed.
This is a sign of accidental dural puncture, just give a smaller dose.
She is probably having a contraction, wait a few minutes and see.
