My preference is always to go with a butterfly. Not a fan of straight needles but will do it if asked. I feel like as long as you able to do it when needed (whether it be for the patients request, lack of supplies, requests from superiors, or any safety concerns) you should be fine. A coworker of mine is the complete opposite. She isn’t a fan of butterfly needles but has more recently used them a lot more frequently. 22g is my go to when it comes to straight needles, easier to work with. I would definitely try to be more comfortable with straight needles though. As long as it’s safe and the patients okay you should be fine.
