interference (EMI) and electromagnetic disturbance from electrosurgery/electrocautery devices, apex locators, lasers, electric handpieces, radiation, and other electronic sources. Additionally, vasoactive drugs, such as epinephrine-containing local anesthetics and other sympathomimetics that may be administered during anesthetic management, may have significant effects upon patients who suffer from tachyarrhythmias. Several guidelines have already been promulgated for surgeons and anesthesia providers in the medical field, and parallel treatment decisions can also be

scientific literature and analysis of expert opinion, clinical feasibility data, open forum commentary, and consensus surveys. This updated advisory focuses on the perioperative management of the patient who has a pre-existing cardiac implantable electronic device (CIED) for the treatment of a bradyarrhythmia, tachyarrhythmia, or heart failure. It applies to all patients with a CIED receiving general or regional anesthesia, sedation, or monitored anesthesia care. Both inpatient and outpatient procedures are addressed by this update.

performed for disuse syndrome, and was later discharged without sequelae. DISCUSSION Pilsicainide is an antiarrhythmic drug classified as Vaughan-Williams class Ic. Because it selectively blocks Na + channels and does not affect K + and Ca 2+ channels, it inhibits conduction to the atrial muscles, the conduction system tissues below the His bundle, and the ventricular muscles. 14 Pilsicainide has arrhythmogenic and negative inotropic effects and is indicated for ventricular and supraventricular tachyarrhythmias that are not associated with

an unknown period of time. Two of these cases presented somnolence and 1 with a seizure. Additional signs and symptoms reported upon presentation included twitches, tachyarrhythmia, or perioral tingling. Comment: The authors of this article note that the maximum safe dose of lidocaine that can be used for airway topicalization is unknown. The maximum recommended dose varies across nations, with most ranging between 3 and 5 mg/kg. A lack of consensus also exists for the body weight type that should be used for calculations.
