So I work in a family practice, being trained on vaccines. Have done 100 so far, minimal issues. 18 month is in for his 12 month shots (delayed), first injection went bad... child flung free from fathers grip with needle still in arm, lost some vaccine, some mild bleeding. Wait and then go in for last 2 injections. Did subcutaneous first. Kid again jerked his arm, lost some vaccine and again bleeding. Nurse supervising told father he needs to get a better grip and advised me to just do last one. I tried but the kid kept squirming. Needle went in then slipped back out. Had to quickly do it again.
Child's arm was red, Puffy, Slightly swollen at injection site. Advised parent to wait 20 minutes to check for reaction they declined. Explained the doctor should assess the injection site as it was a rough injection and it looked puffy. They declined. I told the doctor and noted in the chart. I feel like I never want to do pediatric injections again. The nurse said it happens sometimes but unless we get someone else to restrain the child I feel I cannot trust the parents to secure them.
