About this study
Official title: Characterization of the Repair Process and the Effects of Photobiomodulation in a Donor Area of Partial Thickness Skin Graft After Burn
This is a clinical study with a controlled series of cases, whose objectives were: to evaluate the effects of FBM, using LED, on the repair process of the skin graft donor area treated with Membracel® and LED versus Membracel ®; to evaluate the evolution of the quality of the aspects of the skin donor area, through the score obtained by the modified Bates-Jensen Scale; the intensity of the pain reported by the participants; the size of the wound area until the 7th postoperative (PO) period and the time for re-epithelialization of the donor area. Data collection was performed at the Burn Unit of the General Hospital "Dr. José Pangella", from Vila Penteado, São Paulo, Brazil. The sample consisted of 21 participants and 25 donor areas, 13 of which were from the control group, which received only conventional treatment (Membracel®) and 12 from the experimental group: Membracel® and LED. Data collection instruments were used: medical records of the participants, anamnesis and physical examination, the scales: pain (Visual Analogic Scale - VAS) and Bates-Jensen to accompany the re-epithelialization process and the measurement of donor skin areas in the postoperative period. Quantitative variables were represented by the mean, standard deviation and the median and interquartile range. The comparison of the distributions of these variables between groups was performed using the Mann-Whitney test.
Read the detailed description
The use of FBM, showing beneficial effects on wounds, is well described in the literature. The reported findings include anti-inflammatory action, better tissue organization, acceleration of angiogenesis, stimulation of leukocyte chemotaxis and reduction of donor area size in animals and humans. This is a clinical study with a controlled series of cases, whose objectives were: to evaluate the effects of FBM, using LED, on the repair process of the skin graft donor area treated with Membracel® and LED versus Membracel ®; to evaluate the evolution of the quality of the aspects of the skin donor area, through the score obtained by the modified Bates-Jensen Scale; the intensity of the pain reported by the participants; the size of the wound area until the 7th postoperative (PO) period and the time for re-epithelialization of the donor area. Data collection was performed at the Burn Unit of the General Hospital "Dr. José Pangella", from Vila Penteado, São Paulo, Brazil, from December 2018 to January 2020. The sample consisted of 21 participants and 25 donor areas, 13 of which were from the control group, which received only conventional treatment (Membracel®) and 12 from the experimental group: Membracel® and LED. Data collection instruments were used: medical records of the participants, anamnesis and physical examination, the scales: pain (Visual Analogic Scale - VAS) and Bates-Jensen to accompany the re-epithelialization process and the measurement of donor skin areas in the postoperative period. Participants were identified by Arabic numbers, according to the order of arrival at the Hospital. Quantitative variables were represented by the mean, standard deviation and the median and interquartile range. The comparison of the distributions of these variables between groups was performed using the Mann-Whitney test.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Membracel and LED photobiomodulationRadiation
Participants were positioned so that the skin graft donor area was accessible. A light-emitting diode (LED) plate was covered with sterile transparent and waterproof film to prevent contamination when in contact with the donor area. The application was in contact, with full coverage of the surgical wound and was irradiated with radiant exposure of 1.53J / cm2 and irradiance of 2.55 mW / cm2 for 10 minutes. It is worth mentioning that the LED plate was applied in direct contact with the skin graft donor area in the immediate postoperative period and on the primary cover used (Membracel®) on the 1st, 3rd, 5th and 7th postoperative days. Coverage remained until spontaneous departure. The researcher and the participants used specific goggles for this procedure.
MembracelOther
This group did not receive LED application, remaining with the skin donor area covered by Membracel® and were evaluated under the same conditions.
| Study group | Role | What they receive |
|---|---|---|
| LED group | Experimental | The study had two groups of participants: the LED group (GL) and the control group (GC), both with Membracel®, a porous membrane that regenerates crystalline cellulose, as the primary cover in the donor area of the skin graft (no secondary cover was used) ). In one of the groups (GL), a light-emitting diode (LED) plate was applied, which was covered with sterile waterproof and transparent film to prevent contamination. The participant was positioned so that the skin graft donor area was accessible. The LED plate covered the entire skin donor area and was irradiated with a radiant exposure of 1.53J / cm2 and irradiance of 2.55 mW / cm2 for 10 minutes. The LED plate was applied in contact with the skin graft donor area in the immediate postoperative period and on Membracel® on the 1st, 3rd, 5th and 7th postoperative days. The primary coverage remained until spontaneous removal. Receives: Radiation: Membracel and LED photobiomodulation |
| Control group | Other | The participants remained and were evaluated under the same conditions. The only difference between the groups is that no LED photobiomodulation session was applied to the control group. Receives: Other: Membracel |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the Bates-Jensen Wound Assessment Tool (BWAT)
This scale evaluates size, depth, edges, detachment, type and amount of necrotic tissue, type and amount of exudate, edema and hardening of the peripheral tissue, skin color around the wound, granulation tissue and epithelization. The measurement scale is of the Likert type, with five points, with 1 indicating the best condition of the wound and 5, the worst condition. The total score is obtained with the sum of all the items and can vary from 13 to 65 points, with the highest scores indicating the worst conditions of the wound. The items: size, depth, edges, and detachment should be scored with zero when the lesions are healed. The instrument contains two items: location and form - which are not part of the total score.
Measured: Every two days until wound reepithelialization
Change in the Analogic visual scale
The scale allows for "validation" by the participant, as he or she experiences pain and is therefore an expert on the pain pattern, location, intensity and nature.
Measured: Every two days, until the 7th day after the procedure.
Time for donor area reepithelialization
The LED Group and Control Group donor areas were evaluated for time to reepithelialization. They were considered completely reepithelized when no exudate was noted, the participant reported no pain with exposure of the wound to ambient air and was completely devoid of Membracel coverage and hematic crusts.
Measured: Once a week

Time frame: Every two days until wound reepithelialization
This scale evaluates size, depth, edges, detachment, type and amount of necrotic tissue, type and amount of exudate, edema and hardening of the peripheral tissue, skin color around the wound, granulation tissue and epithelization. The measurement scale is of the Likert type, with five points, with 1 indicating the best condition of the wound and 5, the worst condition. The total score is obtained with the sum of all the items and can vary from 13 to 65 points, with the highest scores indicating the worst conditions of the wound. The items: size, depth, edges, and detachment should be scored with zero when the lesions are healed. The instrument contains two items: location and form - which are not part of the total score.
Change in the Analogic visual scale
Time frame: Every two days, until the 7th day after the procedure.
The scale allows for "validation" by the participant, as he or she experiences pain and is therefore an expert on the pain pattern, location, intensity and nature.
Time for donor area reepithelialization
Time frame: Once a week
The LED Group and Control Group donor areas were evaluated for time to reepithelialization. They were considered completely reepithelized when no exudate was noted, the participant reported no pain with exposure of the wound to ambient air and was completely devoid of Membracel coverage and hematic crusts.
