Favorable tissue effects of quantum molecular resonance device (Vesalius) compared with standard electrocautery. A novel paradigm in lung surgery.
BACKGROUND
Electrosurgical devices are largely employed in thoracic surgery but their use is burdened by extensive necrosis and second intention healing.


METHODS
A rat model of thoracotomy was performed on 46 adult male rats using a standard electrocautery or a new quantum molecular resonance (QMR) instrument called Vesalius. Skin, muscle and lung specimens were obtained immediately and 2 weeks after surgery to evaluate acute and late effects.


RESULTS
Both in the short- and long-term study, Vesalius produced less severe tissue damage than that of standard electrocautery.


CONCLUSIONS
The use of the QMR device may provide an alternative to gold-standard electrosurgical devices in thoracic surgery.
