In this video, we demonstrate the procedure for the installation of an automated periodic stimulation electrode on the vagus nerve for monitoring nerves during thyroid surgeries in a porcine model. This helps in the correct identification of the target nerve during surgical procedures.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Surgical procedure Begin with an anesthetized pig intubated with an electromyography (EMG) tube. Wear sterile surgical gloves and use povidone iodine with cotton swabs to disinfect the neck surgical site. Make a transverse collar incision about 10-15 cm in length with a scalpel to expose the neck and the larynx. Rais…

Materials
| Criticare systems | nGenuity | 8100E | physiologic monitoring, including capnography, electrocardiography (ECG) and monitoring of oxygenation (SaO2) |
| Intraoperative NIM nerve monitoring systems | Medtronic | NIM-Response 3.0 | monitor EMG activity from multiple muscles. If there is a change in nerve function, the NIM system may provide audible and visual warnings to help reduce the risk of nerve damage. |
| Standard Prass Flush-Tip Monopolar Stimulator Probe | Medtronic | 8225101 | Tips and Handles. For locating and mapping cranial nerves in the surgical field, the single-use Standard Prass Monopolar Stimulating Probe features a flush 0.5 mm tip diameter. The probe is insulated to the tip to prevent current shunting. Individually sterile packaged. |
| APS (Automatic Periodic Stimulation) Electrode* | Medtronic | 8228052 / 8228053 | 2 mm/ 3mm. The APS Electrode offers continuous, real-time monitoring. The electrode is placed on the nerve and can provide early warning of a change in nerve function. |
