7.3.3 Preparing the Patient's Skin Prior to Placing Electrodes
The skin is a poor conductor of electricity. Therefore preparation of the patient's skin is important
to facilitate good electrode contact to skin.
A
Shave hair from sites, if necessary.
A
Wash sites thoroughly with soap and water (Never use ether or pure alcohol, because this
increases skin impedance).
A
Rub the skin briskly to increase capillary blood flow in the tissues and remove skin scurf and
grease.
7.3.4 Directions for Use of Fetal Spiral Electrode
1)
Remove the fetal spiral electrode from package, leaving the electrode wires locked in the
handle notch.
2)
Gently bend the guide tube to the desired angle.
3)
With the patient in the dorsal lithotomy position, perform a vaginal examination and clearly
identify the fetal presenting part.
4)
Holding the drive handle, ensure the spiral electrode is retracted approximately one inch (2.5
cm) from the distal end of the guide tube.
5)
Place the guide tube firmly against the identified presenting part.
6)
Maintain pressure against the fetal presenting part with guide and drive tubes. Turn the drive
tube by rotating the drive handle clockwise until gentle resistance is encountered. Resistance
to further rotation and recoil of the drive handle indicates attachment. This will usually occur
after one complete rotation.
7)
Release the electrode wires from the handle notch and straighten them. Slide the drive and
guide tubes off the electrode wires.
8)
Insert the safety cap into DECG cable.
