The medical practice or technique of Cauterization is a medical term describing the burning of the body to remove or close off a part of itin a process called Cautery which destroys some tissue
>, in an attempt to mitigate damage, remove an undesired growth, or minimize other potential medical harmful possibilities such as infections, when antibiotics are not available. The practice was once widespread and is still used in remote regions of the world such as within the wild lands of places such as central Africa for treatment of wounds. Its utility before the advent of antibiotics was effective on several levels of utility: useful in stopping severe blood-loss, to close amputations, useful in preventing infections, including complications from septicaemia.
The main forms of cauterization used today in the first world are electrocautery and chemical cautery— where both are for example prevalent in the removal of unsightly warts. Cautery can also mean the branding of a human, either recreational or forced. Accidental burns can be considered cauterization as well.
History
Cauterization was used to stop heavy bleeding, especially during amputations. The procedure was simple: a piece of metal was heated over fire and applied to the wound. This would cause tissues and blood to heat rapidly to extreme temperatures in turn causing coagulation of the blood thus controlling the bleeding, at the cost of extensive tissue damage.
Cautery is described in the Hippocratic Corpus. The cautery was employed for almost every possible purpose in ancient times: as a ‘counter-irritant’, as a haemostatic, as a bloodless knife, as a means of destroying tumours, etc. Later, special medical instruments called cauters were used to cauterize arteries. These were first described by Abu al-Qasim al-Zahrawi (Abulcasis) in his Kitab al-Tasrif. Abu al-Qasim al-Zahrawi also introduced the technique of ligature of the arteries as an alternative to cauterization. This method was later improved and used more effectively by Ambroise Paré.
Electrocautery
Electrocauterization is the process of destroying tissue using heat conduction from a metal probe heated by electric current (much like a soldering iron). The procedure is used to stop bleeding from small vessels (larger vessels being ligated) or for cutting through soft tissue. Unlike electrocautery, Electrosurgery is based on generation of heat inside tissue, using electric current passing through the tissue itself.
Electrocauterization is preferable to chemical cauterization because chemicals can leach into neighbouring flesh and cauterize outside of the intended boundaries.
Ultrasonic coagulation and ablation systems are also available.
Chemical cautery
Many chemical reactions can destroy tissue and some are used routinely in medicine, most commonly for the removal of small skin lesions (i.e. warts or necrotized tissue) or hemostasis. The disadvantages are that chemicals can leach into areas where cauterization was not intended. For this reason, laser and electrical methods are preferable, where practical. Some cauterizing agents are:
- Silver nitrate: Active ingredient of the lunar caustic, a stick that traditionally looks like a large match-stick. It is dipped into water and pressed onto the lesion to be cauterized for a few moments.
- Cantharidin: An extract of the blister beetle that causes epidermal necrosis and blistering; used to treat warts.
Nasal cauterization
If a person has been having frequent nose bleeds, it is most likely caused by an exposed blood vessel in their nose. Even if the nose is not bleeding at the time, it is cauterized to prevent future bleeding. The different methods of cauterization include burning the affected area with acid, hot metal, lasers, or silver nitrate. Such a procedure is naturally quite painful. Sometimes liquid nitrogen is used as a less painful alternative, though it is less effective. In the few countries that permit the use of cocaine for medicinal purposes, it is occasionally used topically to make this procedure less uncomfortable, cocaine being the only local anesthetic which also produces vasoconstriction, making it ideal for controlling nosebleeds.
Religious beliefs
Some followers of Islam believe that cauterization is prohibited, as can be found in Sahih Bukhari.
Volume 7, Book 71, Number 584
Narrated Ibn 'Abbas:
(The Prophet said), "Healing is in three things: A gulp of honey, cupping, and branding with fire (cauterizing)." But I forbid my followers to use (cauterization) branding with fire."
Volume 7, Book 71, Number 587:
Narrated Jabir bin Abdullah:
I heard the Prophet saying, "If there is any healing in your medicines, then it is in cupping, a gulp of honey or branding with fire (cauterization) that suits the ailment, but I don't like to be (cauterized) branded with fire."
In spite of the above, several cases of thermal cauterization are seen in some Muslim countries.
