Continuous long-term intra-arterial infusion in the unrestrained rabbit
Laboratory Animal Science
|October 1, 1978
Summary
Researchers developed a new technique for continuous common carotid artery infusion in rabbits. This method allowed for prolonged intra-arterial drug delivery in unrestrained animals for up to 61 days.
Area of Science:
- Veterinary medicine
- Surgical techniques
- Pharmacology
Background:
- Continuous intra-arterial infusion is crucial for drug delivery studies.
- Previous methods for rabbit carotid artery catheterization were invasive or limited in duration.
Purpose of the Study:
- To describe a novel technique for chronic catheterization and intra-arterial infusion of the rabbit common carotid artery.
- To enable prolonged drug delivery studies in unrestrained rabbits.
Main Methods:
- A technique utilizing a swivel apparatus, acrylic head mount, and silicone rubber sleeve was developed.
- The method facilitated catheterization and infusion into the common carotid artery of rabbits.
Main Results:
- The technique was successfully applied to 29 unrestrained rabbits.
- Continuous intra-arterial infusion was maintained for periods extending up to 61 days.
Conclusions:
- This technique provides a reliable method for long-term intra-arterial infusion in rabbits.
- It supports advanced research in pharmacology and drug delivery using the rabbit model.
