RESUMEN
BACKGROUND: Management of cardiovascular implantable electronic devices (CIEDs), including pacemakers and implantable cardioverter defibrillators, for surgical procedures is challenging due to the increasing number of patients with CIEDs and limited availability of trained providers. At the authors' institution, a small group of anesthesiologists were trained to interrogate CIEDs, devise a management plan, and perform preoperative and postoperative programming and device testing whenever necessary. METHODS: Patients undergoing surgery between October 1, 2009 and June 30, 2013 at the University of Washington Medical Center were included in a retrospective chart review to determine the number of devices actively managed by the Electrophysiology/Cardiology Service (EPCS) versus the Anesthesiology Device Service (ADS), changes in workload over time, surgical case delays due to device management, and errors and problems encountered in device programming. RESULTS: The EPCS managed 254 CIEDs, the ADS managed 548, and 227 by neither service. Over time, the ADS providers managed an increasing percentage of devices with decreasing supervision from the EPCS. Only two CIEDs managed by the ADS required immediate assistance from the EPCS. Patients who were unstable postoperatively were referred to the EPCS. Although numerous issues in programming were encountered, primarily when restoring demand pacing after programming asynchronous pacing for surgery, no patient harm resulted from ADS or EPCS management of CIEDs. CONCLUSIONS: An ADS can provide safe CIED management for surgery, but it requires specialized provider training and strong support from the EPCS. Due to the complexity of CIED management, an ADS will likely only be feasible in high-volume settings.

Elderly patients are increasingly referred for complex surgery, but are at particular risk for coronary artery disease. One strategy to prevent perioperative cardiac events in elderly patients is to employ perioperative beta-blockade, but doing so has the potential to increase the incidence of congestive heart failure, perioperative hypotension, bradycardia, and stroke. This article examines common comorbidities in the elderly who may benefit from the chronic use of beta-blockers, prophylactic perioperative use of beta-blockers including timing, dosage, and choice of beta-blocker, the pharmacologic effects of aging, and recommendations on the use of beta-blockers.
