Multiple cannulation of the primate superficial lateral coccygeal vein

Area of Science:

• Veterinary Medicine
• Primate Research
• Surgical Techniques

Background:

• The superficial lateral coccygeal veins are crucial for vascular access in non-human primates.
• Effective cannulation techniques are vital for physiological monitoring and experimental procedures in Macaca fascicularis.

Purpose of the Study:

• To describe a surgical method for cannulating the superficial lateral coccygeal veins in Macaca fascicularis.
• To evaluate the utility of this cannulation for continuous infusions and blood sampling.

Main Methods:

• Surgical exposure of the superficial lateral coccygeal veins in Macaca fascicularis.
• Cannulation using polyethylene tubing for vascular access.
• Administration of continuous infusions and collection of serial blood samples.
• Cannula removal 12-18 hours post-insertion.

Main Results:

• Successful surgical cannulation of the superficial lateral coccygeal veins was achieved.
• The cannulation facilitated both continuous intravenous infusions and serial blood sample acquisition.
• The indwelling cannula remained functional for the 12-18 hour experimental duration.

Conclusions:

• Surgical cannulation of the superficial lateral coccygeal veins provides a reliable method for vascular access in Macaca fascicularis.
• This technique supports extended experimental protocols requiring infusions or repeated blood sampling in this primate model.
