Computerized bipolar diathermy with scissors and forceps in cutaneous surgery.
BACKGROUND
Bipolar diathermy coagulates tissue as effectively as monopolar with less lateral tissue injury and no risk of interference with cardiac pacemakers or joint prostheses.


OBJECTIVE
To test a novel computerized bipolar diathermy machine for combined cutting and coagulation in dermatologic surgery.


METHODS
A divided cable was used to deliver current from a computerized bipolar diathermy unit to both scissors and forceps. The bipolar diathermy unit senses tissue contact with the instruments and starts automatically; a built-in microcomputer measures tissue impedance and automatically terminates the current when tissue coagulation is achieved.


RESULTS
The equipment has been used successfully in more than 200 patients undergoing dermatologic surgery. The advantages were a reduced operating time and a more secure hemostasis. The microprocessor controlled bipolar diathermy unit minimized any tissue adherence to the instruments during use.


CONCLUSIONS
We recommend the use of insulated scissors and computerized bipolar diathermy for safe and efficacious coagulation and cutting in dermatologic surgery.
