Randomized Controlled Trial Comparative Study Clinical TrialHemodynamic and blockade effects of high/low epinephrine doses during axillary brachial plexus blockade with lidocaine 1.5%: A randomized, double-blinded study.
Although epinephrine commonly is added to local anesthetics for regional anesthesia, rarely it may cause undesirable hemodynamic side effects. This study compared the hemodynamic and blockade effects of 25 and 200 microg epinephrine during axillary brachial plexus blockade with lidocaine 1.5%. ⋯ Low-dose epinephrine offers more stable hemodynamics and similar blockade, and thus may be beneficial for patients undergoing forearm and hand surgery who are at risk for tachycardia and/or hypertension.
