Complications/ Limitations / Risk
  • Not recommended for routine blood collection. (B601.2.w2)
  • Not suitable for administration of medication. (B601.2.w2)
  • Failure to apply sufficient pressure, for a sufficient time (several minutes) over the collection site after the catheter or needle has been removed may cause significant haemorrhage and haematoma formation. (B601.2.w2)
  • Ischemic necrosis may result if the central auricular artery is used. (B601.2.w2)
Equipment / Chemicals required and Suppliers
  • Over-the-needle catheter recommended, particularly for serial samples.
  • A 24-gauge 3/4 inch catheter can be used in the central auricular artery. (J213.1.w1)
Expertise level / Ease of Use
  • This procedure should only be carried out by an individual with appropriate clinical training and practical experience. This would usually be an experienced veterinarian or experienced veterinary technician/nurse
Cost / Availability
  • Costs are those of consumables (EMLA cream, catheter etc.) and personnel time.
Legal and Ethical Considerations In some countries there may be legislation restricting the use of this type of technique to licensed veterinarians. For example in the UK: "The Veterinary Surgeons Act 1966 (Section 19) provides, subject to a number of exceptions, that only registered members of the Royal College of Veterinary Surgeons may practice veterinary surgery." (See: LCofC1 - RCVS Guide to Professional Conduct 2000 - Treatment of Animals by Non-Veterinary Surgeons).
