Epinephrine test dose in children: is it interpretable on ECG monitor?

Abstract

An increase in T-wave amplitude can easily be detected by carefully observing the ECG monitor or an ECG printout within a minute following the accidental i.v. administration of 0.1 ml x kg(-1) of 1% lidocaine-epinephrine (0.5 microg x kg(-1)) regional anesthetic test dose in children under sevoflurane anesthesia.
