In patients with implanted electrical devices, electrocautery has the potential to burn tissue around the device or to reprogram it; thus, use of bipolar electrocautery is preferred. However, focal use of bipolar electrocautery during scalp reconstruction is usually time-consuming because of the abundant vascularity and the frequent retraction of vessels after the incision, and insufficient hemostasis often results. Optimization of hemostasis is needed in these patients.
