I am terrified that I may have caused harm to a patient, but not know it. Some how I managed to give a patient IV BENTYL! I know how huge a mistake that is, and I have been upset, crying and going to pieces every since it happened. Some how in my head, I got Bently and Benadryl combined as one (dont know how), and diluted it, and give it. My patient got very light headed, I immediatly realized what I done. It passed within minutes, and the patient seemed to be ok. I told the doctor, and he didnt seem too concerned. He said that if the patient was ok after 20 minutes, it should be ok. The patient seemed to be ok, but how can I know if further damage will be done? Is it possible that something horrible will happen to this patient? I have been so worried sick over this. Can anyone elaborate on this? I have searched and searched for information on this and other than seeing it should not be given IV, and "may cause thrombosis" I cannot find out if it would be instant, or a week later or what. I am terrified for the patient. I just want to know if the patient is safe "now".
