In 1899 Austrian chemist von Zaynek determined the rate of heat production in tissue as a function of frequency and current density, and first proposed using high-frequency currents for deep heating therapy. [7] In 1908 German physician Karl Franz Nagelschmidt coined the term diathermy, and performed the first extensive experiments on patients. [8]
Cyclodestruction by diathermy was first performed by Weve in 1933. [11] In 1949, Berens et al. described cyclo-electrolysis. [11] Cyclocryotherapy was first described by Bietti in 1950. [12] Cyclodestruction by cyclophotocoagulation was first performed by Beckman et al., in 1972, using a ruby laser. [13] ECP was developed by Martin Uram in 1992 ...
Diathermy is electrically induced heat or the use of high-frequency electromagnetic currents as a form of physical therapy and in surgical procedures. The earliest observations on the reactions of the human organism to high-frequency electromagnetic currents were made by Jacques Arsene d'Arsonval .
The use of the bipolar option does not require the placement of a return electrode because the current only passes between tines of the forceps or other bipolar output device. Electrosurgery should only be performed by a physician who has received specific training in this field and who is familiar with the techniques used to prevent burns.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
The pores on a standard surgical mask are 5-15 μm in diameter, which is inadequate in completely protecting operating room personnel from the harms of surgical smoke. [3] [5] Due to studies evaluating particles passing through standard surgical masks, some suggested that more effective masks such as HEPA-filters and N95 should be used to provide better protection from cellular debris. [3]
Pneumatic retinopexy is an office-based procedure often used for small and uncomplicated retinal detachments, particularly those involving a single tear in the superior part of the retina. [9] [10] A gas bubble is injected into the vitreous cavity to push the retina back into place against the back of the eye.
