11.2.2.3 Electrode Placement for Surgical Patients
Electrode placement during surgery is dependent on the type of surgery being
performed. For example, with open chest surgery, the electrodes might be placed
laterally on the chest or on the back. In the operating room, artifact can sometimes
affect the ECG waveform due to the use of electrosurgery equipment. To help reduce
this, place the electrodes on the right and left shoulders, the right and left sides near
the stomach, and place the chest lead on the left side at mid-chest. Avoid placing the
electrodes on the upper arms. This will cause the ECG waveform to be too small.
WARNING
z
When using Electrosurgery equipment, patient leads should be placed in
a position that is equal distance from the Electrosurgery electrotome
and the grounding plate to avoid burns to the patient. The
Electrosurgery equipment wire and the ECG cable must be kept
separated and not allowed to tangle.
z
When using Electrosurgery equipment, never place the ECG electrodes
near the grounding plate of the Electrosurgery device. This will cause a
great deal of interference with the ECG signal.
