One-step method for catheterising the jugular vein of cats to enable repeated blood sampling

Area of Science:

• Veterinary Medicine
• Animal Science
• Surgical Techniques

Background:

• Jugular vein catheterization is crucial for diagnostics in cats.
• Previous methods may be invasive or less efficient for serial sampling.
• Optimizing catheter length is essential for patient safety and sample quality.

Purpose of the Study:

• To develop and evaluate a one-step method for jugular vein catheterization in cats.
• To determine the optimal internal catheter length for adult cats using radiography.
• To assess the impact of serial blood sampling and heparin flushes on feline haematocrit and total solids.

Main Methods:

• A novel one-step catheterization technique was employed for feline jugular veins.
• Radiography was utilized to ascertain appropriate internal catheter dimensions.
• Serial blood samples were collected over 48-hour periods, with intermittent heparin flushes.
• Haematocrit and total solids were measured to evaluate physiological effects.

Main Results:

• A 97% success rate was achieved in collecting blood samples using a 19 G, 30.5 cm catheter.
• The catheter was successfully maintained in situ for two 48-hour periods.
• Significant decreases in haematocrit and total solids were noted in all cats.
• No clinically significant blood loss or coagulation abnormalities were detected.

Conclusions:

• The developed one-step jugular catheterization is an effective method for serial blood sampling in cats.
• The technique is safe, with minimal adverse effects on feline haematological parameters.
• This method provides a reliable approach for intensive monitoring and research in feline medicine.
