Neutral electrodes (NE) are used in electro surgery for the return of the current to the ESU (electrosurgical unit); they are placed on the patient and monitored by a CQM (Contact Quality Monitoring) safety system that is incorporated in the ESU. In the paper the benefits and drawbacks of different CQM system are described. The Standard IEC 60601-2-2 requests volunteer experiments for NE testin...

Pigmentation of gingiva is most often a physiologic phenomenon resulting from deposition of endogenous melanin by melanin granules of melanocytes in the epithelium. Although not a medical problem or a disease entity, it is a major concern among young individuals as it hampers esthetics. To restore the ‘pinkness’ of the gums, various techniques such as scalpel method, bur abrasion, electrosurger...

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...

Laparoscopic minilaparotomy in 6 patients using the Maher abdominal elevator facilitated both quicker enucleation and morcellation of the myoma and suture of the myoma cavity. Myoma reduction in 12 patients by electrosurgery resulted in a 60% reduction in myoma diameter with failure in 2 patients. This technique may avoid myomectomy and be particularly useful in patients with infertility or nea...

Electrosurgery is broadly used in a wide variety of surgical procedures, yet its underlying mechanisms of interaction are poorly characterized. Fundamentals of electrosurgery have not changed much since the 1930s—cutting is still performed using continuous RF waveforms, leaving a collateral damage zone of hundreds of micrometers in depth. Pulsed waveforms with variable duty cycle are used mostl...

Since the electrosurgical instruments are commonly used in a wide variety of surgical specialties, understanding of the properties of these instruments is very important to prevent the potential complications. We report the case of a patient who sustained a third-degree dermal burn caused by contact with the ground plate of the electrosurgical system. This burn healed with surgical treatment. S...
