This video appears to be a veterinary student drawing blood from the external jugular vein. Her technique is poor. She does check her landmarks to verify needle placement. The alcohol was applied but somewhat randomly. I’m not sure if the needle stick site is the same as the alcohol. She didn’t scrub the site with alcohol either. She had difficulty finding the vein too. She had to “dig” for it: It’s something frowned upon in nursing and painful to the patient.
Personally, I don’t think drawing blood from the external jugular is safe because they could puncture the carotid artery or lung especially when they’re digging around.
