Agnikarma (Thermal Cautery) is an Ancient Medical Technique derived from the Indian system of medicine, Ayurveda. The technique of Agnikarma
has been designed to relieve various muscular and joint disorders.
The most important procedure of the Shalya Chikitsa (surgical treatment). It comprises of two words i.e Agni and Karma. “When Samyaka
Dagdha Vrana produced by Agni with the help of various Dravyas called as Agnikarma”. The Agnikarma (Thermal Cautery) involves a procedure
whereby heat is transferred to the affected parts of the body using a metal Shalaka (metal rod) in various procedure heat is used directly
or indirectly all these are come under the Agnikarma. Agnikarma is effective and superior among all surgical procedure. Agnikarma has important
role in the Vataj and Kaphaj Vyadhi involving the Dhatu that are predominant with Pṛuthvi and Aap Mahabhuta. On the basis of Lok Puruṣa Samnaya
Sidhant Agni that exit in the body (Bhutagni, Dhatwagni, etc.) have similar properties that exit outside the body. Agni (fire) is better than
alkali in action of burning; it is said so, because disease treated by burning will not recur again and also because, those diseases which are
incurable by the use of medicines, sharp instruments and alkalis may be cured by Agnikarma. Dalhana has mentioned Agnitapta Shastras that prevent
sepsis in surgical procedure. Agnikarma is also useful after Shastra Karma to avoid recurrence for eg. Kadara
Sastrakarma. Due to these properties Agnikarma is accepted as superior than other procedures. Cauterization was used to stop heavy bleeding, especially during amputations. The procedure is simple: a piece of metal will be heated over fire and applied to the wound
Agnikarma as Tau-Dam
Tau-dam is a basically a traditional Himalayan therapy practiced by the rural Himalayan people for liver troubles, stomach troubles, backache, etc. Tau therapy is generally practiced by the older people of village and is compulsory for 6 month to 1-year old children. A 45- 60 cm long iron rod is called the tau, which is sharply curved at one end and has one or two holes depending upon the diseases. In this therapy, tau device is placed on burning fire till it gets red-hot. And after branding it, they massage the affected area with the mustard or olive
oil. In the dam technique, fresh seeds of Terminalia chebula or Anaphalis araneosa are burned on fire and touched on the required part of the body for only few seconds. After this, like tau, the effective area is massaged with the mustard or olive oil.[1]

Inspection of defective Agnikarma and management
1) Plushtha Dagdha
If the Shalaka is not properly heated then it will produce this type of Dagdha.
If the Shalaka is not properly heated then it will produce this type of Dagdha.
Management
For Plushtha Dagdha (burns of the first degree),warming of the body (increasing the body temperature)and administration of drugs / medicines of hot propertiesshould be given; when the temperature of the body becomes increased, the blood becomes liquefied; water by nature is cold in potency and hence makes the blood thick to coagulate, so that, only heat gives comfort.

2) Durdagdha
When the physicians are unskilled hand or patient is shaking his body parts due to fear of burn then Durdagdha can occur.
Management
In Durgagdha (burns of the second degree) the physician should resort to both warm and cold therapies, application of Ghee, poultices and bathing the body should be done in cold state only.
3)Ati-Dagdha (burn of the fourth degree)
This complication is produced due to more heat which is transferred from the red hot Shalaka to the diseased part. In Ati Dagdha the torn (hanging loose) muscles should be removed followed by cold therapies, then the physician should apply the paste of rice, bark of Tinduki
mixed with ghee or cover the wound with leaves of Guduchi or aquatic plant (like lotus etc.). All the treatments which are similar to that of Visarpa of Pitta origin should be done. Madhuchhisthadi Ghrita contains Madhuchhistha, Madhuka, Lodhra, Sarjarasa, Manjishtha, Chandana and Murva, should be macerated together and then cooked with Ghee, is best for healing of wound in all kinds of burns.
4)Daha (Burning pain)
More or less burning pain is experienced by each andevery patient who uses to take Agnikarma Chikitsa. Thismay be treated by Ghrutakumari Patra Swarasa.
Dushtha Vranata (Sepsis of wound)
After Agnikarma, it should be observed for anycomplications. If there is any sign of sepsis, treat the patient accordingly.
Pashchat Karma
Pathya Apathya
In Agnikarma procedure, it is necessary that it should be healed without any complications. So, all the Pathya- Apathyas which have been described by Acharya Sushruta are advised here. It is utmost advisable to the patient that “Do not allow water to touch the SamyakDagdha Vrana site for one Ahoratra (24 hours)”. The complete Ropana (healing) of theVrana should be observed. Agnikarma Chikitsa can be repeated after 7 days.
Agnikarma In Moden Era
In modern medicine era, there is no use of therapeutical burn i.e. Samyak Dagdha vrana. But on the other hand, use of Agnikarma for other way around is used nowdays. There are procedures as mimic to Agnikarma aren practiced in modern era.
Electrocautery
It is a most useful instrument in surgical procedure which consists of platinum wire can be heated to red hot by using an electric current. Use of this electric cautery to cut the tissue or to coagulate the bleeding points, so this application of electro cautery is ideal for removing small skin tags, papiloma and also to control the bleedingduring surgical procedures.
Diathermy
The basic principle is to deliver high frequency current to the human body by means of active electrode and this after passing through the tissue to be diathermied returns via a return electrode. The intense heat produced by thepassage of current destroys it in different ways depending on the type of current used cutting current is undamped and produce cutting effect secondary to intense heat generation within the tissue. It is hemostatic and no bleeding can occur. Blended current is a combination of two types of waves introducing both cutting and coagulating effects. Most new surgical units deliver low voltage cutting or blended current from a solid state generating unit through an isolated bipolar system which is considered the safest.
