Effective Date: October, 2005 Approval: See Authorization
Supersedes Protocol: None Contact: Clinical Staff Education
Reviewed Jan. 2008 May 2009 November 2011
PURPOSE: To provide guidelines for set-up and operations of the Hyfrecator at a UWMF
DEFINITION: A Hyfrecator is an electrocautery
unit used for the removal of lesions from the skin.
And for cautery during procedures.
SETTINGS FOR HYFRECTOR UNIT:
High control setting is 1-30, with a normal setting at
8-12; Low control setting is 1-20 with a normal setting of 1-5.
The provider will set and adjust the control setting as needed during the procedure.
POLICY: The clinical staff will utilize the following guidelines to properly set-up and assist with
a Hyfrecator procedure on a UWMF patient.
SUPPLIES: Provider order, Patient record, Cautery Unit - Tip & Cautery Handle
Needle (provider preference), Sterile and Non-sterile handle sheaths
Cotton Tipped Applicators, Gauze, Alcohol pads
1. Check provider’s order and clarify any inconsistencies.
2. Wash hands and gather equipment.
3. Introduce yourself, identify the patient and provide privacy.
4. Explain procedure to the patient.
5. Assess the patient and surroundings for potential hazards.
Note: No grounding of patient is necessary with the CONMED single polar cautery unit,
but be sure patient is not touching any metal such as on the arm rests of chairs.
Caution: Cautery should not be used in the presence of oxygen or with patients with
pacemakers and internal defibrillators.
6. Use sterile or non-sterile handle sheath (as appropriate for procedure on Hyfrecator handle).
Place tip into top of sheath.
7. Turn Unit on to setting determined by provider (low or high).
8. Provider will check that power light is on and a low "buzz" is heard when holding the "on"
switch of the handle.
9. Assisting the provider (as needed)
Using a cotton tip applicator, roll back and forth over the bleeding wound, cauterizing as
you isolate the "bleeders", using a steady hand and pinpoint touch.
Active bleeders are cauterized, followed by the skin edges. If bleeding is minimal, a
topical hemostatic agent may be used instead of cautery.
10. If wound is large, or excessive cautery is required, you may rinse the area with sterile saline
11. After use the entire unit is wiped down with disinfectant so it is ready for next patient use.
Handle is placed back into unit, tip is discarded (if disposable),
12. When completed, remove gloves and wash hands.
13. Document in the patient’s record:
Care given to the patient, including vital signs (if taken)
Post care instructions given to the patient of family
Patient questions or concerns, along with future appointments (if needed).
