Question about securement of ETT in burn patients

Thank you for the info. Our PICU just opened doors to burn patients and we are in the process of developing a protocol to secure ETT and decrease the occurence of accidental extubation in these patient population considering, not only the risk of extubation, but also the difficulty in re-intubating them. One of my follow-up questions to your method is about the frequency of tie changes. How often does that majority of the time? BID, every 2 days? We use most often than not Bacitracin ointment on facial burns. Does this method withstand the concoction of ointment, secretions & serous drainage? Do you have other guideline special to your unit like mandatory nasal intubation for all burn patients, cuffed ETT, RT practices? Quite a number of questions here..hope you won't tire out. Thanks a bunch!
