Initially we usually change ties with every dressing change - twice a day. Our patients use primary silvadene to the face, unless grafted then they have sulfamylon soln with exudrys. If they are grafted all over the face they will sometimes anchor the tube to the jaw then no ties are needed. Our patients are rarely nasally intubated. They are typically intubated about 3 to 4 weeks & then trach. We have our own respiratory therapists designated to our unit. They handle the cuffs, only peds under 8 are not cuffed ett. We both take turns suctioning patients. I love caring for burns! Bring on the questions.
