Certain surgical and procedural scenarios require specific considerations for patients with pacemakers or ICDs due to the potential impact on device function:
- Ablation Procedures: During cardiac ablation, the proximity of the ablation catheter to the pacemaker or ICD leads can cause damage to the device or its leads. This risk necessitates close coordination with the electrophysiology team, which will typically involve reprogramming the device before and after the procedure to ensure its proper function.
- Cardioversion: For patients requiring cardioversion, it is crucial to ensure that the pacemaker or ICD is appropriately managed. The energy from cardioversion can potentially reset or damage the device. The device should be interrogated both before and after the procedure to confirm it is functioning correctly, and adjustments may be necessary to prevent inappropriate shocks or pacing. When external cardioversion or defibrillation is required, place the pads in an anterior-posterior orientation, keeping them well away from the generator.
- Radiation Therapy: When radiation therapy is planned, especially if the treatment field includes the area near the pacemaker or ICD, special precautions must be taken. Radiation can interfere with the device’s function or even cause permanent damage. The radiation oncology team should collaborate with the electrophysiology team to plan and execute the treatment safely. Shielding the device and possibly relocating the treatment field away from the device are common strategies to mitigate these risks.
- Endoscopy and Colonoscopy: Procedures involving electrocautery, such as those performed during endoscopy or colonoscopy, can interfere with pacemakers or ICDs. It is essential to assess the need for reprogramming or magnet application based on the type of electrocautery used and the proximity to the device.
In the app: the Master Anesthesia app's Defibrillation calculator (Calculators, then Defib) returns weight-based defibrillation and cardioversion energies, handy when planning backup pads and energy for a patient with a device.
Understanding the specific risks associated with these procedures allows anesthesia providers to take appropriate precautions, ensuring both the safety of the patient and the continued proper functioning of their pacemaker or ICD.
| Procedure | Device concern and precaution |
|---|---|
| Cardiac ablation | Proximity of the ablation catheter can damage the device or its leads; coordinate closely with electrophysiology, typically reprogramming before and after the procedure |
| Cardioversion | Cardioversion energy can reset or damage the device; interrogate before and after, pads anterior-posterior and well away from the generator |
| Radiation therapy | Radiation can interfere with device function or cause permanent damage; radiation oncology and electrophysiology plan together, commonly shielding the device or relocating the treatment field |
| Endoscopy and colonoscopy | Electrocautery used during these procedures can interfere with the device; assess the need for reprogramming or magnet application based on the type of cautery and proximity to the device |
