BACKGROUND Electrosurgical units are the most common type of electrical equipment in the operating room. A basic understanding of electricity is needed to safely apply electrosurgical technology for patient care. METHODS We reviewed the literature concerning the essential biophysics, the incidence of electrosurgical injuries, and the possible mechanisms for injury. Various safety guidelines ...

Use of electrosurgery or laser surgery in the presence of metallic implants has been implicated in generating heat-induced injury to peri-implant bone, with the subsequent loss of osseointegration. Studies involving lasers offer conflicting results, while in the case of the electrosurg, little research has been published supporting or refuting these claims. This study measured local heat effect...

Electrosurgery which can also be called as radiosurgery has been used in dentistry for more than 50years. Electrosurgery is a controlled precise application of radiofrequency electrical current to the soft tissue site to be cut which is achieved by means of carefully designed electrodes. Electrosurgery is used in almost all branches of dentistry. Electrosurgery is a continuously evolving field ...

If you saw a low-lying cloud that was labeled clearly with its contents, and the label contained the words benzene, carbon monoxide, formaldehyde, hydrogen cyanide, methane, phenol, styrene, and toluene, would you go out of your way to walk through that cloud and inhale those toxic chemicals? Of course not. But you expose yourself to these same toxic chemicals each time you participate in a sur...

A 62-year-old man with a chronic cough presented with atelectasis of the left upper lobe on chest X-ray. Chest computed tomography showed an atelectasis in the left upper lobe with bronchial wall thickening, stenosis, dilatation, and mucoid impaction. We performed bronchoscopy and found a well-circumscribed mass on the left upper lobe bronchus. The mass was removed by flexible bronchoscopy usin...

The dermal electrosurgical shave excision is a fast and inexpensive method of removing epidermal and dermal lesions. The procedure is ideally suited for pedunculated lesions raised above the level of the surrounding skin. It consists of repetitive, unidirectional, horizontal slicing of a cutaneous lesion with a no. 15 blade followed by electrosurgical feathering to smooth out the wound edges. A...
