I am in my last semester of school and I have clinicals in ICU. Well my preceptor had me change the inner cannula on a trache. The patient had the trache for years (metal type) and they changed it to a plastic one a few days before. I was wearing clean gloves and was told not to touch the part that goes in. Well even though I knew not to touch it I somehow managed to while trying to insert it. I didnt even realize I did it until I put it in and thought about it. My preceptor never said a thing, but I feel like a complete idiot. My preceptor is really cool but I was hoping for a recommendation from him and I feel like I blew it. Any advice or words or wisdom would be appreciated.
