& Management / Disease
Investigation & Management / Techniques:
- Central auricular artery. (B601.2.w2)
- Useful to measure blood pressure in the severely ill rabbit. (J213.1.w1)
- Femoral artery (rabbit under general anaesthesia). (B601.2.w2)
- Medial saphenous artery - prominent, running along the medial aspect
of the hind limb. (P113.2005.w2)
- Clip or shave over the artery.
- Apply EMLA cream and wait 45-60 minutes if using the central
auricular artery in a conscious rabbit. (B601.2.w2,
30 minutes. (B601.16.w16)
- Wipe the skin with 70% isopropyl
- Slowly insert the catheter or needle into the artery.
- Gently pull back on the syringe to collect blood.
- Remove the catheter or needle, and apply pressure over the site
for several minutes. (B601.2.w2,
|Appropriate Use (?)
- Blood gas analysis.
- Acid-base status evaluation.
- Arterial blood pressure measurement and monitoring.
(B601.2.w2, B602.33.w33, J83.20.w1,
|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
- Ischemic necrosis may result if the central auricular artery is
|Equipment / Chemicals required and Suppliers
- Over-the-needle catheter recommended, particularly for serial
- A 24-gauge 3/4 inch catheter can be used in the central auricular
|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
- Costs are those of consumables (EMLA cream, catheter etc.) and
|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).
