Blood inflow into vascular catheters following injection of saline solution and contrast medium. Model experiments. 1979

M Dahlborn, and U Söderlund

Using an experimental model of the arterial system, inflow of blood into polyethylene catheters following injection of two contrast media, isotonic and hypertonic saline solutions was investigated. The experiments included an analysis of the influence of the density of the solutions and the orientation of the catheter as well as the effect of single fluid injection and continuous flushing of the catheter.

UI	MeSH Term	Description	Entries
D008793	Metrizamide	A solute for density gradient centrifugation offering higher maximum solution density without the problems of increased viscosity. It is also used as a resorbable, non-ionic contrast medium.	Amipak,Amipaque
D008794	Metrizoic Acid	A diagnostic radiopaque that usually occurs as the sodium salt.	Metrizoate,Benzoic acid, 3-(acetylamino)-5-(acetylmethylamino)-2,4,6-triiodo-,Isopaque,Metrizoate Sodium,Triosil
D008954	Models, Biological	Theoretical representations that simulate the behavior or activity of biological processes or diseases. For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.

D001775	Blood Circulation	The movement of the BLOOD as it is pumped through the CARDIOVASCULAR SYSTEM.	Blood Flow,Circulation, Blood,Blood Flows,Flow, Blood
D002404	Catheterization	Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.	Cannulation,Cannulations,Catheterizations
