I am a newer peds nurse who works on a peds heme onc unit and primarily deal with central lines and ports. I have recently been floated several times to different units which primarily have IV access. I am able to identify IV infiltrates on the older kiddos but have been having difficulty identifying infiltrates on the babies,especially if they are a little chubby. Obviously if it will not flush, the baby cries when flushing ect then I know its bad but other wise I have a hard time telling. I recently had a baby who didn't cry when flushing or touching around the side and the surrounding site was not cool to touch as it sometimes is with infiltrates however when we looked at the IV at change of shift the nurse thought it was slightly swollen. I didn't think it was however after removing the armboard and dressing it clearly was. I felt horrible that I didn't notice it but her arms were so chubby I really didn't see it. It was not a bad infiltrate however I do not want this to happen again. Any tips/tricks advice? thanks.
