Cautery During Surgery

Patients with DBS occassionally need other operations. We are quite proud that many of our patients have gone on to require hip and knee replacements because of their increased mobilization after DBS. Surgeons should use bipolar cautery if possible. In an article in the British Journal of Anesthesia (2005)  95:424-427, Dr. Davies reported, “The manufacturers’ advice is to avoid electrocautery. If electrocautery is necessary, bipolar mode should be used. If unipolar electrocautery is essential, the ground plate should be kept as far away from the neurostimulator and leads as possible and positioned so that the pulse generator and leads are not situated between the surgical site and the ground plate.”

Patients with the new generation of Medtronic ACTIVA or PERCEPT products can have MRI investigations. There is a strict protocol to follow (see guidelines below). Patients with Boston Scientific or St. Jude/Abbott products have not yet been cleared for MRI. Our patients can call the DBS Clinic (604 875 4111 ext 69584) to find out what device they have implanted.
