The most commonly stated mode of diathermy used was cutting and coagulation together. However, only 44% accurately defined the difference between monopolar and bipolar diathermy with only 4% able to define the differences in modes. Thirty-six percent of surgeons did not know the reason for pad placement when using monopolar diathermy. Operative Principles Surgical diathermy produces radio frequency( 300kHz- 3MHz), alternating current, and patient’s body forms part of an electric circuit The passage of current through the tissue produces a heating effect beneath each electrodes A high frequency current flows through active electrode Cell ruptured-fumes or evaporates. Return path through dispersive electrode RF generation can be activated by a foot switch or finger switch on the surgical handle.

1. Over a well vascularised site. 2. surgical disciplines. A diathermy machine converts elec-tricity of the main supply (240V; 50 Hz) into high fre-quency current (>100,000 Hz) to minimize the risk of elec-trical shocks. In monopolar mode, the current from the diathermy enters the patient through the active electrode and exits through the grounding pad.

Use an adult size pad where possible; otherwise, a paediatric size. Never cut or fold a pad to fit a site. The ideal application site must consider the procedure, patient position and current flow away from ECG electrodes. Avoid placement near scars or implants sites, and consult a cardiologist when a patient is wearing a pacemaker.

Before using the endoscope, we found a burn on patient's left calf, where the grounding pad had been placed. Hand-controlled diathermy units have been used for monopolar diathermy for many years, but the unique movements necessary for bipolar forceps have meant that a hand-held solution has been trickier. When undertaking extremely fine work, any change in pressure or hand position could cause inadvertent movement of the forceps, and so any solution requires careful ergonomic design. Diathermy usage in patients with either a pacemaker or an ICD can result in electrical interference that may initiate inappropriate shock, inhibition, reprograming, or damage to the device. 5–7 Preventative strategies include programing the PPM to asynchronous VOO or DOO mode (ie, pulse generator delivers a pacing stimulus at a fixed rate without sensing capabilities), application of a Monopolar diathermy used for correction of ankyloglossia Tuli A, Singh A 1 Assistant professor, Department of Pedodontics and Preventive Dentistry, Assistant professor Department of Periodontics1, Place the film with the pads back inside the plastic bag, squeeze the excess air out of the bag, and then completely seal it for storage. Proper Pad Placement Ensures the Best Results. In order to achieve the best results from your Compex, you will need to know the proper muscle stimulation pad placement.
In urology, diathermy can destroy tumors or infected tissue, treat obstructions, remove tissue for observation and cauterize blood vessels to prevent excessive bleeding.

Power settings can be adjusted from the surgical field with the use of the electrosurgical pencil. Conmed uses their Aspen Return Monitor (ARM) for the utmost in patient safety. ARM monitors the pad placement and automatically shuts off the power outfut if it senses an alarm situation.

Bipolar cautery is favored.
This is due to its versatility and clinical effectiveness. In monopolar electrosurgery, the active electrode is in the surgical site.

The patient return electrode is somewhere else on the patient’s body. AN ELECTROCAUTERY PAD, EQUIPMENT SET UP AND FOR CORRECT PLACEMENT. A. B. 9 Best Practices: Grounding Pad Monopolar Electrocautery Skin Pad Required For the high power surgical uses during anesthesia the monopolar modality relies on a good electrical contact between a large area of the body (Typically at least the entire back of the patient) and the return electrode or pad (also known as dispersive pad or patient plate). Severe burns (3rd degree) can occur if the contact with the return electrode is insufficient, or when a patient comes into contact with metal objects serving as an unintended (capacitative) leakage path to Earth/Ground. Positive steps towards diathermy safety DON’Ts in placing patient plates DON’T allow fluids to pool at the patient site.
