Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the efficacy of pulsed dye laser (PDL) and carbon dioxide (CO2) laser in conjunction with usual care (MED) for the treatment of hypertrophic burn scars and will determine the optimal sequence and timing of lasers and usual care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigator will compare usual care (MED), which will be offered to all patients, to two types of laser treatment (PDL and CO2), which the investigators hypothesize to be beneficial. The timing and sequence of therapy will be randomized, but all patients will receive some form of laser treatment. If the investigators simply stopped at the end of Aim 1, the investigators would complete a traditional randomized control trial (RCT), with some patients potentially receiving laser treatment. However, the investigators are interested in determining whether the sequence of laser treatments is beneficial; therefore, the investigators will be employing a sequential multiple assignment randomized trial (SMART) design. Because of the nature of the study and SMART design, the investigators will offer all patients some form of laser therapy.
