Outcome Measures

Primary Outcomes (1)

  • Incidence of Atrial Fibrillation events in routine ECG and continous HOLTER ECG for the length of the hospital stay.

    Patients are randomized to a treatment or a sham group. The corresponding device is prepared by a third person according to the double-blind setting for the surgeon. The DUCEST Neurostimulator V needle-electrodes are applied post-operatively to stimulate the R.auricularis of the vagus nerve located at the Fossa triangularis. Connecting the needle-electrode cables to the Neurostimulator V activates the device. (The stimulation intensity can be adjusted from 0,05mA to 1,2mA, default value is 0,4mA). The starting stimulation intensity will be adjusted to 1mA and takes place at 1Hz continuously for 40 minutes, followed by a 20 minute break. After 7 days the electrodes are replaced and applied to the other ear of the patient. A plaster with a plastic mounting clip is attached on the shoulder of the patient. The Neurostimulator is connected to the mounting clip. After 14 days or at hospital discharge of the patient, the device is unmounted and the needle-electrodes are removed.

    07-14 days post operative

Secondary Outcomes (1)

  • Measurement of postoperative inflammation markes, using plasma values of CRP, TNF-alpha, IL-6, and IL-10

    07-14 days post operative

Interventions

The DUCEST Neurostimulator V needle-electrodes are applied post-operatively to stimulate the R.auricularis of the vagus nerve located at the Fossa triangularis. Connecting the needle-electrode cables to the Neurostimulator V activates the device. (The stimulation intensity can be adjusted from 0,05mA to 1,2mA, default value is 0,4mA). The starting stimulation intensity will be adjusted to 1mA and takes place at 1Hz continuously for 40 minutes, followed by a 20 minute break. The built-in 3V battery lasts for approx. 14 days. After 7 days the electrodes are replaced and applied to the other ear of the patient. A plaster with a plastic mounting clip is attached on the shoulder of the patient. The Neurostimulator is connected to the mounting clip. After 14 days or at hospital discharge of the patient, the device is unmounted and the needle-electrodes are removed.

DUCEST Neurostimulator V Group A

The DUCEST Neurostimulator V needle-electrodes are applied post-operatively at the Fossa triangularis. Connecting the needle-electrode cables to the Neurostimulator V activates only the signal lamp but not the device.

DUCEST Neurostimulator V Group B
