Percutaneous, ultrasonographically guided technique of catheterization of the abdominal aorta in calves for serial blood sampling and continuous arterial blood pressure measurement.
The study describes a technique of ultrasonographically guided transcutaneous catheter implantation into the abdominal aorta of 29 6- to 8-week-old German Holstein calves. Catheters were implanted between the left transverse processes of L3 and L4, left in place for 2 days and used for serial blood sampling and continuous measurement of blood pressure. Complete cell counts and clinical examination were performed before, as well as 1 and 5 days after implantation. Catheterization was successful in all calves. The catheter was patent for blood sampling and pressure recordings at all times. A significant decrease in red blood cells was found in all animals after catheterization, which remained reduced for 5 days. Clinical signs of anaemia were absent. In conclusion, ultrasonographically guided catheterization of the abdominal aorta provides a continuous arterial access in calves, whereby the minimal invasive technique and the ultrasonographical guidance reduces accidental tissue trauma and pain for the animal.
