Abstract
Objective: The aim of this study was to evaluate the fire risks, associated with harmonic scalpel, in a established mechanical model of oropharyngeal/laryngeal surgery.
Methods: A standard PVC endotracheal tube (ETT) was inserted into a degutted, whole raw chicken through which 100% oxygen was piped at 10 L/min. The inflated cuff of the tube was grasped and sectioned with the jaws of a standard high-power ultrasonic dissection system Ultracision (Ethicon). Then the whole ETT was grasped and cut, leaving the device in contact with the ETT for 2 more minutes. In a second step under the same conditions an electrosurgical device was placed into the chicken cavity and activated at the chicken tissue near the ETT at a setting of 20 W. All trials were repeated to ensure accuracy.
Results: No ignition could be produced with the harmonic scalpel under any operation mode settings. In all cases the ETT was cut through by the high-power ultrasonic dissection system with some fumes and brown discoloration at the site of impact. The electrosurgical device easily caused flames within seconds.
Conclusions: Harmonic scalpel appears to be a safer tool than electrosurgical devices in the setting of open cavity surgery in oxygen-enriched environments with respect to the presence of flammable medical PVC devices as ETT or catheters.
