Exploring the effectiveness of Vacuum-Assisted Closure (VAC) therapy in dermatology: A single-arm prospective interventional study.

After screening, all patients with chronic ulcer will be chosen.

Before starting treatment, detailed history, clinical examination of patients will be done.

The patient will be informed about the treatment given and need for hospital stay during the procedure.

Informed written consent will be taken from each patient.

Data will be collected by a single examiner and recorded in case proforma.

Pus culture was taken from the wound prior to the start of dressing.

The wound is first debrided and irrigated with normal saline, ensuring adequate hemostasis, and the peri-wound skin is dried.

A sterile foam dressing is applied to evenly distribute negative pressure across the entire wound bed.

A Ryle’s tube is placed within the foam and connected to a vacuum pump via suction tube.

The wound is then sealed with an adhesive drape, covering the foam, tubing, and extending 3–5 cm beyond the wound margins to ensure a watertight and airtight seal.

This is followed by gamjee dressing and crepe bandage application.

The dressing is typically changed on the third day.

The negative pressure is maintained at 75 to 125mmHg.

Depending on the wound depth and size, number of vac dressing is decided to a maximum of 4 weeks.

Later the patient was followed up with betadine dressing.

After 4 weeks, digital photographs will be taken and compared with the baseline.

The efficacy of VAC therapy will be assessed by improvement in wound area, circumference, length, width, microbial clearance and presence of granulation tissue.

This measurement will be made by imitoMeasureTMapp, granulation tissue presence will be assessed using visual photographs and microbial clearance by culture reports.

Patient’s assessment of improvement will be recorded by visual analogue scale.

The safety of VAC therapy will be assessed by the side effects associated with the therapy.
