Q

What is an electrocautery used for?

A
  • for coagulation of small blood vessels in the skin.
  • A probe with a metal loop which has a direct current (electrons flowing in one direction) is used. The heated wire comes in contact with the tissue

Q

Cryosurgical equipment?

A
  • Cryogens or refrigerants are the bases or liquids applied to tissues via probes in order to extract heat from tissues. Liquid nitrogen is the most commonly used refrigerant

Q

What is Diathermy?

A
  • use of a high frequency alternating electrical current which produces local heat at the site of application. It is used for cutting through tissues as well as causing coagulation (haemostasis)

Q

What is bipolar diathermy?

A

Two separate electrodes are applied across the tissue. The handpiece looks like a pair of tissue forceps and can only be used for coagulation. This type gives the greatest control over the location of coagulation.

Q

What is monopolar diathermy?

A

used for both cutting and coagulation. With monopolar coagulation, there is a flow of electrical current from the handpiece (active electrode) through the animal’s body to a ground plate.

Q

Precautions for diathermy?

A
  • Patients have to be properly grounded or earthed
  • ground plate must be in contact with the animal: a dampened laparotomy sponge or electrosurgical conduction gel is used to facilitate contact with the plate
  • Improper earthing may lead to burning to the patient.
