BACKGROUND Electrosurgery for dissection and haemostasis should be associated with minimal thermal spread to surrounding tissues. This study investigated lateral thermal spread following ex vivo application of four commonly utilized instruments. METHODS Monopolar and bipolar diathermy (power settings 20, 30 and 40 W), the Harmonic Scalpel and Ligasure (power settings 1, 3 and 5) were studied after application to standardized porcine muscle cuts for 5, 10 or 15 s. Temperatures generated at the… CONTINUE READING
