October 17, 2024 updated by: Aya Gamal Fawzy El-Sayed, Cairo University

Electromotive Drug Administration of Magnesium Sulphate on Hypertrophic Scar Post-Burn

In this study 80 patients will be randomly assigned into two equal groups (40 patients for each group):

  1. Group A: Experimental: Magnesium Sulphate Iontophoresis for Postburn Hypertrophic Scar The study group includes 40 postburn hypertrophic scar patients will receive Magnesium Sulphate iontophoresis twice a week for 4 weeks; in addition to their traditional physical therapy program (deep friction massage, stretching and pressure therapy).
  2. Group B: Control: Traditional physical therapy for postburn hypertrophic scar This group includes 40 patients with postburn hypertrophic scar who will receive only the traditional PT (deep friction massage, stretching and pressure therapy) 2 sessions per week for 4 weeks

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  1. Assessment measures and procedures:

    1. High resolution ultrasonography [Time Frame: Change of hypertrophic scar thickness from the beginning of treatment to the end of treatment (after 4 and 12 weeks from the beginning of treatment).

      High frequency ultrasound is the most common used technique for scar assessment. Its inferior resolution compared to optical equivalents is mitigated by its superior penetration depth allowing thickness analysis, even in severe scar thickening. The working mechanism is based on refection of sound waves of structures with different acoustic impedances and the analysis of the refection time to determine the depth of the structure. The penetration depth ranges from the upper dermal layers to full-thickness skin and subcutaneous structures, depending on the employed frequency (Elrefaie et al., 2020).

    2. Patient and observer scar assessment scale [Time Frame: Assessing the change of patient and observer scar assessment scale score from baseline (beginning of treatment) to 4 and 12 weeks after treatment.

    The scar will be rated numerically on a ten-step scale by both the patient and doctor on six items: vascularity, pigmentation, thickness, relief, pliability, and surface area on the Observer Scale. The Patient Scale consists of pain, itchiness, color, stiffness, thickness, and irregularity of the scar. Minimal score means good progression and maximum score means the scare is worse (Lenzi et al., 2019).

  2. Treatment procedures:

Iontophoretic drug delivery system (phoresors II auto model PM850 IOMED) The phoresors II auto model PM850 IOMED allows the user to deliver a specific dose from 0 to 80 mA/min, control the current from 0 to 4 mA and automatically calculates required time for the selected dose. Current ramp-up and down, shut-off, error messages and safety checks are also performed automatically. The builtin option for manual current shut-off is an added safety feature (Teslim et al., 2013).

  • Electrodes: Active-Anode (Drug Delivery).
  • Drug Used: MgSO4 Aqueous Solution.
  • Drug Ion Polarity: Positive Polarity. Prior to intervention, skin sensation will be assessed using warm water in a test-tube (temperature), pin prick (pain) and cotton wool (light touch) to ascertain the skin sensitivity.

Before each treatment, the surface area of the scar will be cleaned with cotton wool and alcohol to reduce skin resistance. 2.5 ML MgSO4 will be applied to the active positive electrode via a syringe with concentration 100 mg/cm2 (it's available in hospitals and not found in pharmacies), active electrode will be placed directly over the hypertrophic scar. The dispersive electrode will be applied to the skin 6 inch distal from the active electrode (Evans et al., 2001).

The dose needed will be selected in the device which is 75 mA/min (Teslim et al., 2013) then the current will be increased gradually depending on subject tolerance, ranging from 2 to 4 mA, the device will automatically calculate the required time for the selected dose. The interventions will be repeated twice a week for 4 weeks (Teslim et al., 2013). If a subject reports any sensation other than tingling, the treatment will be stopped, the electrodes will be removed and the skin will be inspected (Evans et al., 2001).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria
