mainlined? without a heplock?
Forgive my ignorance, but I think I'm not understanding what you mean by "mainlined."
An ER pt. who presents with n/v nearly always has an IV started (a lock), labs drawn, and then a bag of NSS hung to rehydrate them. Reglan, Zofran, Anzemet, Compazine or any other med can be administered IV push through this line.
If the pt. is going to have a reaction, then certainly it will have a faster onset w/an IV med than w/a med given by mouth.
You also mentioned IV Valium ... I've seen Ativan used more instead, except pre-op. Some days in the ER, I'm giving Ativan constantly ...
