Evaluation of efficacy, satisfaction, and complication of fractional carbon dioxide laser treatment with platelet-rich plasma in comparison with fractional carbon dioxide laser alone in the treatment of burn scars

Protocol summary

Study aim
Evaluation of the effectiveness and satisfaction of fractional co2 laser and Platelet-rich plasma (PRP) in the treatment of burn scar
Design
The clinical trial, with parallel groups, double-blind, simple randomized by sealed envelopes, phase 3 on 20 patients
Settings and conduct
The intervention will be performed at the Skin and Stem Cell Research Center. In this study, 20 patients with burn scars will be selected. Patients will receive 3 sessions of fractional CO2 laser treatment with an interval of one month. At the end of the first and third sessions, the SVF will be injected into the selected scar as the treatment group and the physiological serum will be injected at the other scar as the control group.
Participants/Inclusion and exclusion criteria
Inclusion criteria: skin type 1-4, atrophic burn scars in more than one limb from five years ago to the last 3 months. Exclusion criteria: Age under 18 years, Laser treatment in the last three months, Active colloidal scar at the injection site, Coagulation and platelet disorders or a history of taking anticoagulants, Underlying diseases such as diabetes and autoimmune connective tissue disease that affect the wound healing process, Active viral infections, History of malignancy or receiving chemotherapy, Pregnancy, Lactation
Intervention groups
In each patient, three sessions of fractional carbon dioxide laser will be performed on each burn scar every one month. At the end of the first and third session, the platelet-rich plasma will be injected into one of the scars as the treatment group, another scar of the same patient will be injected the physiological serum as the control group.
Main outcome variables
The effectiveness of treatment, patient satisfaction, physician satisfaction

Sample size
Target sample size: 20
More than 1 sample in each individual
Number of samples in each individual: 2
At the end of the first and third session of laser treatment, the stromal vascular fraction will be injected into a scar of the patient as the treatment group. In another scar of the same patient, the physiological serum will be injected as the control group.
Randomization (investigator's opinion)
Randomized
Randomization description
In this study, 20 patients with inclusion and exclusion criteria are selected. In each patient by simple randomization method, one burn scar is selected as the intervention group and another scar of the same patient is selected as the control group. For each burn scar, one envelope is randomly selected from two sealed envelopes. The letter a or b is written on each envelope. Envelopes a belong to the intervention group and envelopes b belong to the control group. The patient does not know to which group each envelope is assigned
Blinding (investigator's opinion)
Double blinded
Blinding description
In this study, the patient is unaware of the type of intervention performed on each burn scar. To blind the patient, a paper cover with the patient's name is attached to the body of the injection syringes. The outcome assessor is a dermatologist who has only images and biometric information of each scar for Vancouver scoring and he does not know the type of intervention. The data analyzer also is a statistician who has only the data to analyze and is not aware of the type of intervention.

Intervention groups

1

Description
Intervention group: Patients will receive three sessions of fractional carbon dioxide laser treatment at one-month intervals. Deka fractional carbon dioxide laser device will be used to perform the laser treatment. Its setting will be determined based on the thickness of the scar and the patient's skin type. At the end of the first and third sessions of laser treatment, the platelet-rich plasma injection will be performed in one of the patients' scars. To prepare it, 20 ccs of blood is taken from the patient. Then, after centrifugation and processing, the Platelet-rich plasma is isolated. It will be injected into the scar with an insulin syringe.

Description
Control group: Patients will receive three sessions of fractional carbon dioxide laser treatment at one-month intervals. Deka fractional carbon dioxide laser device will be used to perform the laser treatment. Its setting will be determined based on the thickness of the scar and the patient's skin type. At the end of the first and third sessions of laser treatment, in another scar of the patient as the control group, 5cc of the physiological serum will be injected with an insulin syringe.
