I applaud the authors' emphasis on the importance of a thorough anesthetic and family history. Furthermore, as the authors stated, the increased incidence of malignant hyperthermia in patients with such muscular defects as strabismus and ptosis must be appreciated, as well as the fact that local anesthetics of the "-amide" variety (eg, lidocaine hydrochloride, mepivacaine hydrochloride, bupivacaine hydrochloride, and others) may be mild triggering agents.

Isolated masseter muscle spasm after succinylcholine must be assumed to portend malignant hyperthermia
