Abstract
A modified surgical procedure for creation of a carotid loop for repeated percutaneous sampling of arterial blood gas was performed on 8 Holstein heifers and 14 horses. This approach permitted sampling of blood gas via fine-needle aspiration (one to three times daily) and/or catheterization for extended periods. It offers several advantages over previously reported techniques, including greater accessibility, absence of postoperative complications such as hematoma formation, and absence of foreign materials supporting the loop.
