Pamber

Hi all, just want some opinions as I'm kind of stressing out about this. This is the first time I've ever had anything like this happen but I placed an IV in a patient tonight (I work in the ED). The IV did not advance completely but I had good blood return and the patient stated they tasted the NS flush when I pushed it. I gave them the dilaudid for pain (kidney stones), and while flushing noticed a bit of resistance if I didn't hold the IV a certain way. Knowing the Phenergan would not go in via IVPB with the IV being positional I diluted the 25 mg Phenergan with 10 mL of NS and pushed over about 10 min. The patient did not complain of any pain or burning, but while flushing with another NS flush I noticed swelling above the IV site. I immediately stopped and pulled the IV, contacted the doctor and pharmacist, and followed directions by applying a cold compress, elevating the arm and watching the area. Patient still did not complain of any pain and the site was no longer swollen or red by the time the patient was discharged. The doctor and my coworkers did not seem worried but I'm stressing because I think it was the Phenergan that infiltrated and I know how damaging that can be to surrounding tissues so I'm wondering what other people think of this situation and what I could have done differently or how to prevent this from happening again.
