What can surgical staff do to reduce influence of electrosurgical interference on adjacent electronic instrument?
Interference produced by the HF surgical equipment may adversely influence the operation of adjacent electronic instruments. If you see abnormal situation in the adjacent equipment, note that it can be because of the action of the HF surgical equipment. The simplest and most effective method to reduce interference is a spatial separation of the two pieces of equipment. For example; if a video monitor during electrosurgery is grainy, snowy, or has lines running through the screen, it should be placed as far away as possible from the ESU and it’s connecting cables. √ Some other suggestions include: • Check all connections to the generator, patient plate, and active accessory to look for possible metal-to-metal sparking. • Interference is usually greatest during high voltage mode such as blend or spray (fulguration). The amount of interference can be reduced by using lower power setting or using a lower voltage mode such as pure cut or soft coag or swift coag. • Plug the power cord of the
