Randomized Controlled Trial Clinical TrialPlasma bupivacaine concentrations and effects of epinephrine after superficial cervical plexus blockade in patients undergoing carotid endarterectomy.
To determine if epinephrine (EPI) added to a solution of bupivacaine (BUP) injected for use in superficial cervical plexus blockade (SCPB) lowers plasma BUP concentrations after injection and whether this addition of EPI resulted in tachycardia, cardiac arrhythmias, or both. ⋯ BUP 0.25% consistently produced the lowest plasma BUP concentrations, particularly when EPI was added to the solution. BUP 0.5% without EPI can produce plasma BUP concentrations previously reported to be associated with central nervous system effects. The use of EPI in this setting does not produce untoward cardiac side effects.

Randomized Controlled Trial Comparative Study Clinical TrialSevoflurane versus isoflurane in patients undergoing coronary artery bypass grafting: a hemodynamic and recovery study.
To determine if sevoflurane provides comparable hemodynamics and recovery characteristics to isoflurane in cardiac anesthesia. ⋯ At MAC equivalent doses, sevoflurane showed comparable hemodynamics to isoflurane. Both agents when used as the primary anesthetic showed similar recovery characteristics, with no statistical difference between them at any stage of the study.
