Comparison of Platelet-Rich Plasma Dressing and Normal Saline Dressing for Wound Healing in Patients With Chronic Diabetic Wounds

After obtaining approval from the institutional review board and obtaining informed consent from study participants, all patients fulfilling the inclusion criteria were included in the study from the surgery indoor department of Gulab Devi Hospital, Lahore. Baseline characteristics, including age (in years), gender (male/female), and history of comorbidities (hypertension/ischemic heart disease/smoking), were assessed by reviewing previous medical records and taking a detailed history. The duration of diabetes (in years), duration of the wound (weeks), size of the wound (measured using a millimeter scale along the longest axis), and class of chronic diabetic wound (III/IV) were documented.

After wound debridement, patients were randomized into two equal groups by block randomization as follows:

Group A: Patients were managed with normal saline dressing. Group B: Patients were managed with PRP dressing. In this technique, the wound was washed with normal saline, and platelet-rich plasma (prepared from the patient's own blood by the hematology department) was injected into the surrounding wound area twice weekly, followed by the placement of a gauze over it.

Dressing was continued for a period of 6 weeks or until wound healing was achieved, whichever was shorter. To assess healing, all patients in both groups were followed up weekly until 6 weeks (study endpoint). The duration required to achieve wound healing was also documented. Additionally, 6 weeks post-therapy, wound size was reassessed. In cases of non-healing, alternative therapy was provided based on the wound condition and the consultant surgeon's advice. All data were recorded in a predesigned proforma and kept confidential.
