Abstract
PURPOSE OF REVIEW: Evidence from retrospective studies suggests that regional anesthesia reduces the risks of major complications associated with carotid endarterectomy compared with general anesthesia, namely: stroke, stroke/death, death and myocardial infarction. RECENT FINDINGS: A superficial cervical plexus block is the regional anesthetic technique of choice. It is as efficacious as a combined (superficial and deep) cervical plexus block and carries substantially less risk of inducing a life-threatening complication from the block placement than a cervical epidural or a deep cervical plexus block. Lidocaine, mepivacaine, bupivacaine and ropivacaine are all suitable agents for this block but bupivacaine provides the longest duration of postoperative analgesia. The addition of epinephrine 1: 300,000 (3.75 microg/ml) reduces maximal blood concentrations of lidocaine and bupivacaine without inducing any adverse hemodynamic effects. SUMMARY: The anesthesiologist should learn how to place a superficial cervical plexus block. The technique is easy to master, effective and carries a low risk of inducing a serious complication.
