I am super afraid of needles and i have to have an iv to put me to sleep for surgery. what can i expect can they give me laughing gas while they do it?

Emla (lidocaine and prilocaine) & clear cover: ~1 prior to planned IV likely=better option; greatly reduces local skin sensation; primary basis of discomfort. However, will need to plan & persistently request/insist on this in advance else rarely done or Emla (lidocaine and prilocaine) on hand plus must be applied to planned IV location & kept in position for about an hour prior using a clear cover; Opsite or clear plastic like food wrap.
