Help!!! I drew up 1gm of Rocephin per Dr's order. Mixed it correctly with 3.6 ml's of sterile saline. Told the Dr. I thought it should be given in split doses. Dr. said he didn't want it split. Wanted it given in one dose. Went into the room (I work in a Dr's office), had the pt. stand (no tables just exam chairs in rooms), administered in Rt. hip. Pt. had tensed leg muscle bracing for injection and immediately got a cramp in the hip. He hobbled around the room, was in a lot of pain. I got him an ice pack and stayed with him. Within 5 mins he was somewhat better but I could tell it still bothered him. I told him 1 gm of rocephin is a hefty dose because of the abcess he had. He said that was okay, whatever the Dr. wanted him to have. I have worried myself sick since yesterday about this. I told the Dr. and he said it was fine. Has anyone else had this type of reaction? Was 3+ ml's too much to inject into the ventrogluteal area? In pediatrics we always did 1ml in each vastus lateralis muscle - 2 injections. Help!!
