The number of days to complete burn wound healing (≥95% reepithelialization), calculated via clinical judgment from the consultant.

The pain evaluation via the FPS-R was performed by the patient himself or herself if aged 5 years or more, or by their caregiver in patients under 5 years of age. The scale consists of six faces, presented horizontally, that depict different degrees of pain, from "no pain" to "most pain possible". A numerical value from 0 to 10 is assigned to each face.

The pain evaluation via CONFORT-B Scale was performed by the physician responsible and assessed the pain based in a behavioral that consisted in six factors: alertness, calmness/agitation, respiratory response (or crying), physical movement, muscle tone, and facial tension.Each factor was scored with values ranging between 1 and 5, generating scores between 6 and 30 points.

The pain evaluation via FLACCr scale was performed by the physician responsible and answered five evaluation categories based on behavioral parameters with combined scores ranging from zero to ten (classified the scores as follows: zero to three (mild pain); four to six (moderate pain) and seven to ten (severe pain).

In the test group, a dressing change was defined as the act of replacing the tilapia skin that did not adhere properly and/or replacing gauze and bandage that is full of exudate, after an evaluation of the dressing (performed every 48 hours). In the control group, a dressing change was defined as the daily act of cleaning the wound and reapplying the silver sulfadiazine cream 1%, which is then covered with new gauze and bandage.
