What are the venous access options during a Colonoscopy?

I always have a problem with the cannula. The last time I had surgery (gallbladder removal) they had to find different veins several times, ended up inserting it through my ankle after many failed attempts, which was all very uncomfortable. I dread this more than the procedures themselves. Is intravenous cannulation absolutely necessary during the colonoscopy? Are there any other options?

Not really if you want anesthesia. The alternative is doing a Cologuard test.
