(1) Avoid contact between the patient's skin and metal objects, wet objects and their own skin.

(2) When using flammable anesthesia machine, alcohol disinfectant or gas in the gastrointestinal tract of the patient, use an electric knife with caution.

(3) Use high-quality negative plates. Use disposable soft polar plates as much as possible, and prohibit cutting, folding and heating the negative plate.

(4) Negative plate area: The effective conductive area of the general polar plate is 65cm2 for children and 129cm2 for adults.

(5) Paste the negative plate at the site where the muscles and blood vessels are abundant, avoid sticking to bone bulges, scars, skin folds or defects, thick fat, near metal grafts, and places where liquid can accumulate; and ensure that the skin at the pasted site is clean and dry 3. Partially no hair.

(6) The negative electrode plate is more than 15cm away from the ECG electrode to avoid that the ECG electrode is in the same path as the electric knife current. For patients with pacemakers, disable or cautiously use high-frequency electrocautery (can be used under the guidance of the manufacturer or cardiologist), or switch to a bipolar electrocautery.

(7) Try to be as close as possible to the surgical incision site (but less than 15cm), avoid crossing the body's cross line, in order to make the shortest path for the current to pass.

(8) The skin area of infants and young children is small, and flat muscle areas such as thighs, backs, and abdomen should be selected for the negative electrode.

(9) Check the integrity of the electrocautery head, handle and wire before the operation, and remove the eschar on the electrocautery head in time during the operation. When the use is stopped, the handle is placed in the pen cover.

(10) Adjust the output power according to the needs of the operation, and do not increase the output power blindly.

(11) The generated smoke and particles are harmful to the human body and should be absorbed in time.

(12) After the operation, slowly remove the entire negative plate horizontally from the patient's skin along the direction of the dermatoglyph and observe the skin condition at the negative plate.

(13) The instrument should be regularly tested and maintained to prevent electric leakage from burning patients and medical staff.
