IDENTIFICATION OF SURGICAL SMOKE

摘要

In one aspect, a method is provided for assessing tumor margins during surgery in a subject undergoing resection by cauterizing along visual boundaries of a tumor to generate gaseous tissue particles; analyzing the gaseous tissue particles to determine a compositional make-up of the gaseous tissue particles; and comparing the compositional make-up of the gaseous tissue particles to a predetermined value of the compositional makeup of one or more non-tumor tissues. In such methods, the surgeon will discontinue cauterization when the compositional make-up of the gaseous tissue particles corresponds to the compositional make-up of one or more non-tumor tissues. The method may use a thermal cautery or a radiofrequency bipolar cautery to resect tumor tissue.
