What is a significant negative aspect of using monopolar cautery in surgeries involving IPGs?

Using monopolar cautery in surgeries involving implantable pulse generators (IPGs) presents a significant risk because it may negatively interact with the device. Monopolar cautery works by passing an electrical current through the body, which can inadvertently affect the functioning of the IPG. This could lead to unintended changes in stimulation, potential damage to the device, or even interference with its intended therapeutic effects. This interaction raises safety concerns, as it can impact patient outcomes and the reliability of the IPG.

Other options do not capture the direct risk posed to the IPG. While increased battery usage, longer procedure times, or limitations on surgical options could also be considerations, they do not directly address the primary concern regarding the interaction between the cautery device and the implanted system. Hence, the interaction with the IPG stands out as the most significant negative aspect in this context.
