8.4.4.4. Electrode Placement for Surgical Patients
While placing electrodes for a surgical patient, the type of surgery should be
considered, for instance, as to a chest surgery, the chest lead electrodes can be placed at
sides or backside of chest. Moreover, while using a surgical electrotome, in order to
reduce the influence of artifacts to ECG waveform, the electrodes can be placed at left and
right shoulders, close to left and right sides of abdomen; the chest lead electrodes can be
placed at left side of chest midst. Do not place the electrodes on the upper arm. Otherwise,
the ECG waveform will be very small.
WARNING：
To reduce the hazard of burns during use of electrosurgical units (ESU), the
ECG electrodes should not be located between the surgical site and the ESU
negative electrode
plate.
Never entangle the ESU cable and the ECG cable together.
When using ESU, never place ECG electrodes near to the negative electrode
plate of the ESU, as this can cause a lot of interference on the ECG signal.
