My 14 year old niece was to get an anesthesia IV in her arm, but the nurse missed the vein and the IV instead entered the arm. They then redid the IV in the other arm, but told none of the adults there what happened. We only knew they made a mistake when my neice told us later on. Is there anything we should watch for, any side effects of the missed IV and the second IV in the other arm? They used Fentanyl, and Versed.
