Yesterday afternoon, I was just getting set to leave from work, and my wife called. I could hear my 4 year old son crying very loudly in the background as my wife asked if I was on my way home yet. She told me that he had injured his finger pretty badly on his bike somehow, and wanted me to meet her at the emergency room. I wasn't sure if insurance would cover the one we wanted to go to, so I had to call my agency to find out if it would and call her back (it did, so we were okay).
It sounded like he had really injured the tip of his pinkie. While on the way there, she told me that she had put a washcloth over the finger, but when she had pulled it off to look at it, she had seen something come off of the tip. She wasn't sure if it was just skin or if it was more, but he wouldn't let her keep the washcloth off long enough to see (plus, she was too squeamish to look for too long). She asked if she could call an ambulance, but I said no way. When I was doing my ER stint while I was getting my EMT-B, AMR brought in a kid who had sliced his finger, and the paramedics had made a comment about how there was no way that required an ambulance. Plus, as an EMT and firefighter, I've taken waaaay too many people to the ER who didn't need an ambulance, and I knew one wasn't needed this time.
