Successful cannulation is typically indicated by the absence of pain or complications following the procedure. When cannulation is performed correctly, the patient should not experience persistent pain or discomfort at the site of cannulation, and there should be no complications such as bleeding or hematoma formation. This outcome suggests that the access site is functioning as intended, allowing the procedure to proceed safely and effectively.

While immediate blood flow and clear catheterization under fluoroscopy are also positive indicators, they may not fully encompass the overall assessment of the patient's response to the procedure. Immediate blood flow can suggest that the cannula is in the correct vascular structure, but it doesn’t provide information about potential complications. Clear catheterization observed through fluoroscopy is valuable for confirming that the catheter is properly positioned, yet again, it doesn't account for the patient's pain response or any complications that may arise. Therefore, the absence of pain or complications is a more holistic indicator of successful cannulation.
