About this study

Official title: Effectiveness Comparison Between the Use of Skin Micro-grafts vs Meshed Split Thickness Skin Grafts in Cutaneous Defects: A Randomized Controlled Clinical Trial

This is a double-blind randomized controlled clinical trial, that compares the percentage of epithelialization of skin defects using the conventional meshed split thickness skin grafts vs skin micro grafts.

Two techniques will be applied in the same patient. The skin defect will be divided in two parts, and with a randomized method each half of this defect will be assigned to one of the two techniques.

Read the detailed description

Split thickness skin graft is the standard technique in skin defects reconstruction.

The etiology of this problem is diverse (burns, infections, trauma, cancer) however, many times the availability of donor areas are insufficient and morbidity and complications that may arise make prohibitive the use of this technique in many situations.

Skin micro grafts technique consists in using a very small part of skin (0.8x 0.8 mm) and keratinocyte growth-factor solution that allows a 1:50- 1:100 skin expansion. It has many advantages: it can be performed with local anesthesia and donor area is tiny.

The study consists in using the conventional and the new technique in the same patient. The skin defect will be divided in two parts, and with a randomized method each half of this defect will be assigned to one of the two different techniques. The result variable will be the "percentage of epithelialization" and will be compared in the two halves. This variable will be measured at day 14 using clinical and image software methods. The patient and the investigator that record the outcome variable will be blinded to the type of technique.

The investigators will take skin biopsies of two halves and will perform pathology studies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Skin micro GraftsProcedure or surgery

    Also called Xpansion micro auto grafting system, micro grafts

    0.8 x 0.8 skin micro graft with graft to graft distance of 4 cm (1:50 expansion) bathed with keratinocyte growth factor solution ( 1.5 ml for each 14 square centimeters of wound)

  • Standard skin graftProcedure or surgery

    Also called split thickness skin graft, skin grafting, skin grafts, medium split thickness skin graft

    Standard split thickness (0.3-0.5mm) skin graft

Study groups in NCT02813213
Study groupRoleWhat they receive
Standard skin graftActive comparatorThis group is comprised of patients' wound halves that will receive meshed (1:3) split thickness skin graft (0.3-0.5mm thickness). This half will be covered with a standard "tie over" dressing. The dressing will be removed at day 5, and then it will be removed every 3 days up to the 14th day.
Receives: Procedure: Standard skin graft
Skin micro graftExperimentalThis group is comprised of the patients' wound halves that will receive skin micro grafts. To obtain this grafts the investigators will use "Xpansion micro-autografting" system. They will use 0.8 x 0.8 mm skin grafts with a graft to graft distance of 4mm (1:50 expansion).This half will be covered with a special hydrogel dressing with keratinocyte growth factor (Epilife medium with calcium) 1.5ml for each 14 square centimeters of the wound. This half will be covered with a wet adhesive foam dressing and then it will be covered up with a non-adherent interface dressing (tegaderm). The dressing will be removed at day 5, and then it will be removed every 3 days up to the 14th day. Each time of dressing change only the non-adherent interface dressing will be removed, and the area will be bathed with keratinocyte growth factor solution.
Receives: Procedure: Skin micro Grafts

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of epithelialization

    It will be measured with imaging software (comparing color density) in order to calculate the percentage of epithelialization at day 14 compared with the initial wound area

    Measured: 14th day

Secondary outcomes (2)
  1. Histological study

    Study of the histological characteristics of the skin under microscope

    Measured: 14th day

  2. Clinical percentage of epithelialization

    It will be measured with the "irregular patterns" technique that uses different sizes of geometric patterns in order to calculate the area of a irregular surface. Epithelialization will be compared at day 14 compared with the initial wound area.

    Measured: 14th day

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Alejandro Cruz, MD (5534242197, alejandrocruzsegura@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of epithelialization (time frame: 14th day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02813213, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2018.
