As a CNA with a very heavy assignment I have found a few ways to make the brief changes a bit easier and faster. Again make sure the bed is at a comfortable height for you, Of course unfasten the front and tuck the front of it between the legs, if your person can moderately assist you sometimes raising the foot of the bed will help them to get a little more leverage to push from and help the turning process, cloth chucks and draw sheets will be your best friend use them, get the patients body to the opposite side you rolling to and give a count 1,2,3 and roll helping them along the way, Once rolled take the back side of the brief and chuck and roll it into itself, do your peri-care, layer your new brief and chuck and place it in the appropriate position, I put the clean stuff under the soiled stuff, have them roll back onto their back, go to the the side of the bed, position them in the same ready to roll position, roll them on your count, the soiled stuff i there ready to be pulled out, if there is anymore cleaning to do now is the time, apply cream/barrier lotion ect.., unroll the clean stuff and roll the resident back to there back, pull the new stuff through he legs and fasten, and re-position your resident!! I know it seems complicated but once you get the hang of it it will be second nature!! Good luck hang in there and do the very best you can by your residents and you'll be fine!!! Practice makes perfect and remember someone else way will not always work for you... find your way while keeping your people safe and happy!!!
