Failure of an epinephrine test dose to elicit tachycardia after intravascular epidural catheter placement.
A 58-year-old woman who was not taking beta-adrenergic block medication had a lumbar epidural catheter placed intravascular unintentionally. Epinephrine 15 micrograms in 3 ml saline or 2% lidocaine caused an increase in blood pressure and a decrease in heart rate. Observation of the patient for other signs of intravascular injection besides an increase in heart rate is discussed.
